One example of the wireless area networks is a wireless personal area networks.
In some embodiments, another mobile terminal (which may be configured similarly to mobile terminal 100) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the mobile terminal 100 (or otherwise cooperate with the mobile terminal 100). The short-range communication module 114 may sense or recognize the wearable device, and permit communication between the wearable device and the mobile terminal 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the controller 180, for example, may cause transmission of data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114.

As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.
The input unit 120 may be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input, image and video input is often obtained using one or more cameras 121. Such cameras 121 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode.

In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal 100. As another example, the cameras 121 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.

As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.
The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.
The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.
The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor.
The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like).
In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the mobile terminal 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.
A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.
As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.
When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180, the controller 180, and combinations thereof.
In some embodiments, the controller 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.
The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.
If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.
The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.
Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.
The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images.
A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.
The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.
A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.
Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.
The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the users fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the mobile terminal 100.
An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.
A signal output by the optical output module 154 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.
The interface unit 160 serves as an interface for external devices to be connected with the mobile terminal 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to such external device. The interface unit 160 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.
The identification module may be a chip that stores various information for authenticating authority of using the mobile terminal 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 160.
When the mobile terminal 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.
The memory 170 can store programs to support operations of the controller 180 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.
The memory 170 may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The mobile terminal 100 may also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.
The controller 180 may typically control the general operations of the mobile terminal 100. For example, the controller 180 may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.
The controller 180 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller 180 can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein.
The power supply unit 190 receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging.
The power supply unit 190 may include a connection port. The connection port may be configured as one example of the interface unit 180 to which an external charger for supplying power to recharge the battery is electrically connected.
As another example, the power supply unit 190 may be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit 190 can receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance.
Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.
Referring now to
The terminal body may be understood as at least one assembly of the mobile terminal 100.
The mobile terminal 100 will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case 101 and a rear case 102. Various electronic components are incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally positioned between the front case 101 and the rear case 102.
The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151a of the display unit 151 may be mounted to the front case 101 to form the front surface of the terminal body together with the front case 101.
In some embodiments, electronic components may also be mounted to the rear case 102. Examples of such electronic components include a detachable battery 191, an identification module, a memory card, and the like. Rear cover 103 is shown covering the electronic components, and this cover may be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is detached from the rear case 102, the electronic components mounted to the rear case 102 are externally exposed.
As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 is partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. In some embodiments, the rear cover 103 may include an opening for externally exposing a camera 121b or an audio output module 152b.
The cases 101, 102, 103 may be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like.
As an alternative to the example in which the plurality of cases form an inner space for accommodating components, the mobile terminal 100 may be configured such that one case forms the inner space. In this example, a mobile terminal 100 having a uni-body is formed in such a manner that synthetic resin or metal extends from a side surface to a rear surface.
If desired, the mobile terminal 100 may include a waterproofing unit (not shown) for preventing introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, to hermetically seal an inner space when those cases are coupled.
The mobile terminal may be provided with a display unit 151, first and second audio output modules 152a, 152b, a proximity sensor 141, an illumination sensor 142, an optical output module 154, first and second cameras 121a, 121b, first and second manipulation units 123a, 123b, a microphone 122, an interface 160, etc.
Hereinafter, as shown in
However, it is to be understood that alternative arrangements are possible and within the teachings of the instant disclosure. Some components may be omitted or rearranged. For example, the first manipulation unit 123a may be located on another surface of the terminal body, and the second audio output module 152b may be located on the side surface of the terminal body.
The display unit 151 outputs information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
The display unit 151 may be implemented using one or more suitable display devices. Examples of such suitable display devices include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, an e-ink display, and combinations thereof.
The display unit 151 may be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units 151 may be arranged on one side, either spaced apart from each other, or these devices may be integrated, or these devices may be arranged on different surfaces.
The display unit 151 may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180, for example, may generate a control command or other signal corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes.
The touch sensor may be configured in a form of a film having a touch pattern, disposed between the window 151a and a display on a rear surface of the window 151a, or a metal wire which is patterned directly on the rear surface of the window 151a. Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display.
The display unit 151 may also form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit 123 (see
The first audio output module 152a may be implemented in the form of a speaker to output voice audio, alarm sounds, multimedia audio reproduction, and the like.
The window 151a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152a to pass. One alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window 151a and the front case 101). In this case, a hole independently formed to output audio sounds may not be seen or is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal 100.
The optical output module 154 can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller can control the optical output unit 154 to stop the light output.
The first camera 121a can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit 151 or stored in the memory 170.
The first and second manipulation units 123a and 123b are examples of the user input unit 123, which may be manipulated by a user to provide input to the mobile terminal 100. The first and second manipulation units 123a and 123b may also be commonly referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units 123a and 123b may also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like.
Input received at the first and second manipulation units 123a and 123b may be used in various ways. For example, the first manipulation unit 123a may be used by the user to provide an input to a menu, home key, cancel, search, or the like, and the second manipulation unit 123b may be used by the user to provide an input to control a volume level being output from the first or second audio output modules 152a or 152b, to switch to a touch recognition mode of the display unit 151, or the like.
As another example of the user input unit 123, a rear input unit (not shown) may be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal 100. The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules 152a or 152b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit may be configured to permit touch input, a push input, or combinations thereof.
The rear input unit may be located to overlap the display unit 151 of the front side in a thickness direction of the terminal body. As one example, the rear input unit may be located on an upper end portion of the rear side of the terminal body such that a user can easily manipulate if using a forefinger when the user grabs the terminal body with one hand. Alternatively, the rear input unit can be positioned at most any location of the rear side of the terminal body.
Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit 123a in the rear input unit. As such, in situations where the first manipulation unit 123a is omitted from the front side, the display unit 151 can have a larger screen.
As a further alternative, the mobile terminal 100 may include a finger scan sensor which scans a user's fingerprint. The controller 180 can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor may also be installed in the display unit 151 or implemented in the user input unit 123.
The microphone 122 is shown located at an end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds.
The interface unit 160 may serve as a path allowing the mobile terminal 100 to interface with external devices. For example, the interface unit 180 may include one or more of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 180 may be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage.
The second camera 121b is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit 121a. If desired, second camera 121a may alternatively be located at other locations, or made to be moveable, in order to have a different image capturing direction from that which is shown.
The second camera 121b can include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. The cameras may be referred to as an “array camera.” When the second camera 121b is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.
As shown in
As shown in
At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module 111 may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover 103, or a case that includes a conductive material.
A power supply unit 190 for supplying power to the mobile terminal 100 may include a battery 191, which is mounted in the terminal body or detachably coupled to an outside of the terminal body. The battery 191 may receive power via a power source cable connected to the interface unit 160. Also, the battery 191 can be recharged in a wireless manner using a wireless charger. Wireless charging may be implemented by magnetic induction or electromagnetic resonance.
The rear cover 103 is shown coupled to the rear case 102 for shielding the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from an external impact or from foreign material. When the battery 191 is detachable from the terminal body, the rear case 103 may be detachably coupled to the rear case 102.
An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal 100 can also be provided on the mobile terminal 100. As one example of an accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal 100 may be provided. The cover or pouch may cooperate with the display unit 151 to extend the function of the mobile terminal 100. Another example of the accessory is a touch pen for assisting or extending a touch input to a touch screen.
As previously described with regard to
A typical NFC module provided at the mobile terminal supports short-range wireless communication, which is a non-contactable type of communication between mobile terminals and generally occurs within about 10 cm. The NFC module may operate in one of a card mode, a reader mode, or a P2P mode. The mobile terminal 100 may further include a security module for storing card information, in order to operate the NFC module in a card mode. The security module may be a physical medium such as Universal Integrated Circuit Card (UICC) (e.g., a Subscriber Identification Module (SIM) or Universal SIM (USIM)), a secure micro SD and a sticker, or a logical medium (e.g., embedded Secure Element (SE)) embedded in the mobile terminal. Single Wire Protocol (SWP)-based data exchange may be performed between the NFC module and the security module.
In a case where the NFC module operates in a card mode, the mobile terminal may transmit card information on a general IC card to the outside. More specifically, if a mobile terminal having card information on a payment card (e. g, a credit card or a bus card) approaches a card reader, a short-range mobile payment may be executed. As another example, if a mobile terminal which stores card information on an entrance card approaches an entrance card reader, an entrance approval procedure may start. A card such as a credit card, a traffic card, or an entrance card may be included in the security module in the form of applet, and the security module may store card information on the card mounted therein. Card information for a payment card may include any of a card number, a remaining amount and usage history, and the like. Card information of an entrance card may include any of a user's name, a user's number (e.g., undergraduate number or staff number), an entrance history, and the like.
When the NFC module operates in a reader mode, the mobile terminal can read data from an external tag. The data received from the external tag by the mobile terminal may be coded into the NFC Data Exchange Format defined by the NFC Forum. The NFC Forum generally defines four record types. More specifically, the NFC Forum defines four Record Type Definitions (RTDs) such as smart poster, text, Uniform Resource Identifier (URI), and general control. If the data received from the external tag is a smart poster type, the controller may execute a browser (e.g., Internet browser). If the data received from the external tag is a text type, the controller may execute a text viewer. If the data received from the external tag is a URI type, the controller may execute a browser or originate a call. If the data received from the external tag is a general control type, the controller may execute a proper operation according to control content.
In some cases in which the NFC module operates in a P2P (Peer-to-Peer) mode, the mobile terminal can execute P2P communication with another mobile terminal. In this case, Logical Link Control Protocol (LLCP) may be applied to the P2P communication. For P2P communication, connection may be generated between the mobile terminal and another mobile terminal. This connection may be categorized as a connectionless mode which ends after one packet is switched, and a connection-oriented mode in which packets are switched consecutively. For a typical P2P communication, data such as an electronic type name card, address information, a digital photo and a URL, a setup parameter for Bluetooth connection, Wi-Fi connection, etc. may be switched. The P2P mode can be effectively utilized in switching data of a small capacity, because an available distance for NFC communication is relatively short.
Reference will now be made in detail to the preferred embodiments of a control method of a mobile terminal according to the present invention, examples of which are illustrated in the accompanying drawings. It will also be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention.
A mobile terminal of the present invention which may include at least one of the components described above may control an unmanned aerial vehicle 1000.
Hereinafter, the unmanned aerial vehicle 1000 related to the present invention will be described in detail with reference to
The unmanned aerial vehicle (UAV) 1000 related to the present invention is a flying object manufactured to perform a designated mission without carrying a pilot (person). The unmanned aerial vehicle 1000 may be called a drone, an unmanned aerial equipment, a unmanned aerial object, or the like.
Hereinafter, the description of the UAV 1000 may be inferred and applied to an apparatus that is operated on the ground or operated at sea, as well as an apparatus (object equipment) that performs flight, in the same or similar manner.
Also, hereinafter, the description of the UAV 1000 may be inferred and applied to an object in which a pilot (human) is aboard, such as a manned aircraft, a vehicle, or the like, in the same/similar manner.
The UAV 1000 (or a drone) related to the present invention may include at least one of the components described in
For example, the UAV 1000 may include a wireless communication unit. The UAV 1000 may exchange (transmit and receive) data through the wireless communication unit 110 and the wireless communication unit 110 included in the mobile terminal 100.
The UAV 1000 may include an upper case 1001 a lower case 1002, a receiving part 1004, a wing part 1210, a camera 1121, and a controller. Hereinafter, a reference numeral 1180 will be used for the controller of the UAV 1000.
The upper case 1001 and the tower case 1002 provide a space for various components for implementing the UAV 1000. At least one of the components described in
The receiving part 1004 is formed between the upper case 1001 and the lower case 1002 and the wing part 1210 is received in the receiving part 1004. The wing part 1210 may include at least one wing unit. Although the wing 1210 is illustrated as including four wing units, the number of wing units is not limited thereto.
The wing part 1210 may be formed of a propeller 1211 and a main body 1212 including the propeller 1211. The main body 1212 may include at least one of a connection part 1212a connected to the body part and a fixing part 1212b to which the propeller 1211 is rotatably fixed. The wing part 1210 Includes a movable shaft (not shown) for rotatably connecting the connection part 1212a included in the main body 1212.
One area of the main body 1212 is curved so as to be continuously formed with outer surfaces of the upper and lower cases 1001 and 1002 in a receiving mode. When the receiving mode is switched to a flight mode, the movable shaft rotatably moves the connection part 121a so that the wind unit protrudes to the outside of the body part and the fixing part 1212b is disposed on the outside. When the propeller 1211 rotates in the flight mode, the body part flies.
The controller 1180 of the UAV 1000 may control the wing part 1210 based on a request from the mobile terminal 100. Specifically, when a signal requesting movement in one direction is received from the mobile terminal 100, the controller 1180 of the UAV 1000 may control the wing part 1210 so that the UAV 1000 may move in the one direction.
In addition, the UAV 1000 related to the present invention may be equipped with a camera 1121. At least one camera 1121 may be provided.
The controller may transmit a preview image received through the camera 1121 to an external device through a wireless communication unit. For example, the external device may be the mobile terminal 100 related to the present invention.
Here, the preview image refers to an image which is continuously output after received through the camera 1121 according to the flow of time.
The controller 1180 of the UAV 1000 may transmit the preview image received through the camera 1121 to the mobile terminal 100 through the wireless communication unit based on a request from the mobile terminal 100. Accordingly, a preview image received through the camera 1121 of the UAV may be displayed on the mobile terminal 100.
In addition, the UAV 1000 may transmit the preview image to a plurality of mobile terminals 100 through a wireless communication unit. The plurality of mobile terminals 100 may be determined based on terminal information transmitted from the mobile terminal 100 capable of controlling the UAV 1000. In this case, the preview images may be displayed on the plurality of mobile terminals 100, respectively.
The controller 1180 of the UAV 1000 may control the camera 1121 based on a request from the mobile terminal 100. For example, when a request to perform a zoom-in function of the camera is received from the mobile terminal 100, the controller 1180 of the UAV 1000 may control the camera 1121 to perform the zoom-in function and transmit a preview image changed by the zoom-in function to the mobile terminal 100.
Here, it is obvious that the UAV 1000 may be controlled not only based on a request of the mobile terminal 100 but also by a remote controller, a mobile terminal, a fixed terminal, etc., which may control the UAV 1000.
Meanwhile, the mobile terminal 100 related to the present invention may control the UAV 1000 described in
The UAV 1000 related to the present invention may be controlled by at least one mobile terminal 100 or 200. Specifically, the UAV 1000 is controlled by one of a plurality of mobile terminals and may be controlled by another mobile terminal different from the mobile terminal based on a user request or a preset algorithm. As another example, the UAV 1000 may be simultaneously controlled by a plurality of mobile terminals 100.
Hereinafter, at least one mobile terminal capable of controlling the UAV 1000 will be referred to as a first mobile terminal 100, a second mobile terminal 200, and the like.
The first mobile terminal 100 and the second mobile terminal 200 may include at least one of the components described in
In addition, the configurations and features of the first and second mobile terminals 100 and 200 may be performed in one mobile terminal related to the present invention.
Referring to
The mobile terminal 100 related to the present invention may be provided with (installed) an application associated with a function of controlling the UAV 1000. The application may include various functions related to the UAV 1000, for example, a function of connecting the UAV 1000 and the mobile terminal 100 to each other to perform wireless communication, a function of outputting a preview image to the display unit 151 of the mobile terminal 100, a function of controlling the UAV based on a user control command (or user input) input to the mobile terminal 100, or the like.
In addition, the mobile terminal 100 may generate at least one terminal information capable of controlling the UAV 1000 through an application.
Hereinafter, a method for generating the at least one terminal information will be described in more detail with reference to
As shown in (a) of
For example, the first screen information 400 may include an icon 402 associated with a function of generating at least one terminal information and an icon 404 associated with a function of transmitting information of the mobile terminal 100 so that an external terminal may generate the terminal information by using the information of the mobile terminal 100.
When the icon 402 associated with the function of generating at least one terminal information is selected, the controller 180 may output second screen information 410 related to the application on the display unit 151 as illustrated in (b) of
The second information 410 may include information of a UAV to be controlled (that is, a control object) (e.g., a name of the UAV, a unique number, a product number, etc.), an icon 142 associated with a function of selecting (searching) the UAV to be controlled, a group name representing the at least one terminal information, an icon 414 associated with a function of searching for a mobile terminal, at least one searched terminal information, and a graphic object for setting priority of the at least one mobile terminal.
For example, as shown in (b) of
As illustrated in (a) of
For example, if the icon 404 is selected in the second mobile terminal and the third mobile terminal, the second mobile terminal and the third mobile terminal may transmit respective mobile terminal information through the communication unit.
The first mobile terminal 100 activates the communication unit 110 based on selection of the icon 414 associated with the function of searching for the mobile terminal and receives the mobile terminal information through the communication unit. Then, the controller 180 may output the received mobile terminal information to the display unit 151.
Returning to
In the display unit 151 (for example, in the vicinity of the received mobile terminal information), a graphic object for setting priority of the received mobile terminal information may be displayed. The controller 180 may set priority of the received mobile terminal information based on user input applied to the graphic object.
Also, as illustrated in (b) of
When the selection and prioritization of the received mobile terminal information are completed, the controller 180 may generate at least one terminal information capable of controlling the UAV. The at least one terminal information may be grouped into one group.
When prioritization of the received mobile terminal information is completed, third display information 420 related to an application associated with the function of controlling the UAV 1000 may be output to the display unit 151. As shown in (c) of
Returning to
Here, connection between the mobile terminal and the UAV 1000 to perform wireless communication means that a control right that may control the UAV 1000 is set (registered, designated) in the mobile terminal.
For example, the controller 180 of the first mobile terminal 100 may control the communication unit 110 to perform wireless communication with the UAV 1000 based on a user request.
As shown in (c) of
Specifically, when the icon 422 is selected, the controller 180 may activate the communication unit 110 and emits a signal for connection with the UAV. When a response signal is received from the UAV that receives the signal, the first mobile terminal 100 and the UAV 1000 may be connected to each other to perform wireless communication.
In a state where the first mobile terminal 100 and the UAV 1000 are connected to each other, a signal for maintaining the connection may be transmitted and received periodically or at predetermined time intervals.
Also, the icon 422 may be associated with at least one terminal information capable of controlling the UAV. The controller 180 of the first mobile terminal 100 may transmit the at least one terminal information associated with the icon 422 to the UAV 1000 when the icon 422 is selected.
Also, the controller 180 of the first mobile terminal 100 may transmit a control signal for controlling the UAV 1000 to the UAV 1000 through the communication unit 110 (or through wireless communication).
The UAV 1000 receiving the control signal may perform a function corresponding to the control signal based on the control signal received from the first mobile terminal 100. For example, the controller 1180 of the UAV 1000 may control movement of the UAV and a camera and the like provided on the UAV, based on the control signal received from the first mobile terminal 100.
The controller 1180 of the UAV 1000 may transmit a preview image received through the camera 1121 to the first mobile terminal 100 in a state where the first mobile terminal 100 and the UAV 1000 are connected to perform wireless communication.
As illustrated in (d) of
A preview image 432 received from the UAV 1000 and at least one terminal information transmitted to the UAV 1000 may be displayed on the fourth screen information 430. Also, an indicator 434 indicating a mobile terminal currently controlling the UAV 1000 may be displayed in any one of the at least one terminal information.
For example, when the indicator 434 is displayed in the first mobile terminal information, the UAV 1000 may be controlled by the first mobile terminal 100 corresponding to the first mobile terminal information. Being controlled by the first mobile terminal 100 may mean performing a function corresponding to a control signal received from the first mobile terminal 100.
In addition, information indicating priority of the at least one terminal information may be displayed in the fourth screen information 430. The priority means order of transmitting a signal requesting control by the UAV 1000 to a mobile terminal different from the first mobile terminal when it is determined that the UAV 1000 cannot be controlled by the first mobile terminal 100.
Meanwhile, the priority may be changed by the controller 1180 of the UAV 1000. Specifically, the controller 1180 of the UAV 1000 may change priority set for at least one terminal information received from the first mobile terminal 100, based on a preset algorithm (or method).
For example, the controller 1180 of the UAV 1000 may transmit a response request signal (e.g., RF (radio frequency) signal) to mobile terminals corresponding to the at least one terminal information. Thereafter, the controller 1180 of the UAV 1000 may change the priority based on strength of a response signals (e.g., RF signals) transmitted from the mobile terminals. For example, the controller 1180 may set a higher priority from mobile terminal information corresponding to a mobile terminal having a greater strength of the response signal.
As another example, the controller 1180 of the UAV 1000 may change priority set in at least one terminal information transmitted from the first mobile terminal 100 based on an image (preview image) received through the camera 1121 included in the UAV 1000.
Hereinafter, a method of changing priority based on an image received through the camera 1121 will be described with reference to
In
As shown in (a) of
Thereafter, the controller 1180 of the UAV 1000 may change the priority based on the recognized image. Specifically, an image related to the face may be associated with the at least one terminal information.
The controller 1180 may extract an image 440 related to the face included in the image based on an image 432 received through the camera 1121. The controller 1180 may extract (determine) terminal information associated with the image 440 related to the extracted face in the at least one terminal information, based on the extracted image 440 related to the face. Thereafter, the controller 1180 may change the priority order based on the extracted terminal information.
For example, as shown in
For example, in a state that lie second mobile terminal information 200a has a first priority and the third mobile terminal information 300a has a second priority, when the image 440 related to the face recognized in the image 432 received through the camera corresponds to the image related to the face associated with the third mobile terminal information 300a, the controller 1180 may change the third mobile terminal information 300a to a first priority and the second mobile terminal 200a to a second priority.
The controller 1180 of the UAV 1000 may transmit information related to the priority order (for example, information related to the changed priority) to the mobile terminal corresponding to at least one mobile terminal information. In this case, as shown in (c) of
Also, when a priority is not set in at least one terminal information transmitted from the first mobile terminal 100, the controller 1180 of the UAV 1000 may set a priority based on an image received through camera 1121 of the UAV or determine a second mobile terminal to transmit a control request signal.
Through the configuration, in the present invention, a priority may be set based on an image received through the camera of the UAV or a second mobile terminal to transmit a control request signal may be determined, thereby remarkably enhancing reliability and accuracy related to transmission of a control request signal.
Meanwhile, the fourth screen information 430 may be displayed together in at least one mobile terminal corresponding to the at least one terminal information, as well as in the first mobile terminal 100. For example, when the first mobile terminal 100 and the UAV 1000 are connected to perform wireless communication, the fourth screen information 400 may also be displayed on the display unit 151 of at least one mobile terminal (e.g., the second mobile terminal, the third mobile terminal) corresponding to the at least one terminal information.
Meanwhile, the mobile terminal (for example, the first mobile terminal) connected for the first time to perform wireless communication with the UAV 1000 among the at least one mobile terminal may have a higher (greater) control right (grade, level, etc.) than the mobile terminal. That is, the first connected mobile terminal (or the mobile terminal that transmitted at least one terminal information) may be referred to as a master terminal and the remaining mobile terminals (for example, the second mobile terminal and the third mobile terminal) may be referred to as slave terminals.
The master terminal may be the first connected mobile terminal or may have previously been set in at least one terminal information transmitted to the UAV 1000. Also, the master terminal may be changed based on a user request. In addition, the control right of the master terminal may be withdrawn without an approval (acceptance), while the UAV 1000 is being controlled by the slave terminal (the related contents will be described in more detail with reference to
Although not shown, a graphic object associated with a function of controlling movement of the UAV 1000 and a graphic object associated with a function of controlling the camera of the UAV 1000 may be displayed on the display unit 151. For example, when a graphic object associated with a function of moving the UAV 1000 in the left direction is selected, the controller 180 of the first mobile terminal 100 may transmit a control signal associated with the graphic object, that is, a control signal for moving the UAV 1000 in the left direction, to the UAV 1000. The UAV 1000 may control the wing part so that the UAV 1000 may move in the left direction based on the control signal.
Returning to
Thereafter, in the present invention, when it is detected that the UAV enters the predetermined state, a signal requesting control to a terminal other than the first mobile terminal is transmitted based on at least one terminal information transmitted from the first mobile terminal 100 (S420).
Specifically, the controller 1180 of the UAV 1000 may detect that the UAV 1000 enters the preset state, in a state of being connected to perform wireless communication with the first mobile terminal 100.
The preset state may mean a state in which it is impossible to control by the first mobile terminal 100 connected to perform the wireless communication. For example, the preset state may be related to the connected signal.
For example, when strength of a connection signal connected to the first mobile terminal 100 to perform the wireless communication becomes weaker than a reference strength, the controller 1180 of the UAV 1000 may detect that the UAV enters the preset state.
The connection signal may be a signal connected to enable the UAV 1000 and the first mobile terminal 100 to be connected to perform wireless communication, and may be a signal transmitted/received periodically or at preset time intervals as described above.
For example, the strength of the connection signal may become weak when a distance between the first mobile terminal 100 and the UAV 1000 is increased or a factor (e.g., fog, dust, wind, etc.) disturbing wireless communication between the first mobile terminal 100 and the UAV 1000 is increased.
As another example, when a control signal is not received from the first mobile terminal 100 for a predetermined time, when the connection with the first mobile terminal 100 is cut off, or when a connection signal periodically transmitted and received to and from the first mobile terminal 100 is not received by a predetermined number of times (e.g., a state that it is impossible to control by the first mobile terminal), the controller 1180 of the UAV 1000 may detect that the UAV enters the preset state.
As another example, the controller 1180 of the UAV 1000 may detect that the UAV enters the preset state based on receiving a predetermined control signal from the first mobile terminal 100.
The preset control signal may be a control signal transmitted from the controller 180 of the first mobile terminal 100 when the first mobile terminal 100 enters a state in which control of the UAV 1000 is impossible.
For example, the first mobile terminal 100 may include a sensing unit 140 for sensing movement of the mobile terminal 100. When a preset movement is sensed through the sensing unit 140 in a state that the first mobile terminal 100 is connected to perform wireless communication with the UAV 1000, the controller 180 of the first mobile terminal 100 may transmit a preset control signal related to control to the UAV.
For example, the preset movement may correspond to a movement of separating the mobile terminal by the user. That is, the preset movement may be a movement in which the first mobile terminal moves by a predetermined distance or greater within a reference time.
Also, the preset control signal related to the control may be a signal informing that it is impossible to control the UAV 1000 by the first mobile terminal.
In summary, in a state that the UAV 1000 is connected to perform wireless communication with the first mobile terminal 100, the controller 1180 of the UAV 1000 may transmit a control request signal a second mobile terminal different from the first mobile terminal based on at least one of the connected signal strength and received predetermined control signal (or based on entering a predetermined state).
For example, as illustrated in
Thereafter, when the control approval signal is received from the second mobile terminal 200, the UAV 1000 may perform a function corresponding to the control signal transmitted from the second mobile terminal 200. That is, the UAV 1000 may be controlled by the second mobile terminal 200 rather than the first mobile terminal 100.
As described above, when the UAV is connected to the first mobile terminal 100 to perform wireless communication, the controller 1180 of the UAV may receive at least one terminal information capable of controlling the UAV 1000 from the first mobile terminal 100.
The second mobile terminal 200 may be determined based on the at least one terminal information. Priority information may be set in the at least one terminal information. The controller 1180 of the UAV 1000 may transmit the control request signal based on the priority.
For example, when the at least one terminal information includes the second mobile terminal information and the third mobile terminal information and a first priority is set in the second mobile terminal information and a second priority is set in the third mobile terminal information, the controller 1180 of the UAV 1000 may transmit the control request signal to the second mobile terminal corresponding to the second mobile terminal information.
When a control approval signal for the control request signal is received from the second mobile terminal, the controller 1180 may not transmit the control request signal to the third mobile terminal corresponding to the third mobile terminal information, On the other hand, if the control approval signal is not received within a reference time from the second mobile terminal, the controller 1180 may transmit the control request signal to the third mobile terminal.
On the other hand, the controller 1180 of the UAV 1000 may recognize an image related to a face included in the image, based on the image received through the camera 1121 of the UAV. Thereafter, the controller 1180 may determine a second mobile terminal different from the first mobile terminal, based on terminal information associated with the recognized image. Specifically, the controller 1180 may recognize (extract) an image related to a face included in the image using the image received through the camera 1121, and compare the image related to the recognized face and the image related to the face associated with at least one terminal information transmitted from the first mobile terminal. Thereafter, the controller 1180 may extract terminal information associated with the image related to the face corresponding to the image related to the recognized face and transmit the control request signal to the mobile terminal corresponding to the extracted terminal information.
As described above, when at least one terminal information is received from the first mobile terminal 100 and the priority is set in the at least one terminal information, the controller 1180 of the UAV 1000 may determine a second mobile terminal 200 different from the first mobile terminal 100 based on the recognized image and the priority.
As illustrated in
Thereafter, the controller 1180 of the UAV 1000 may transmit a control request signal to the mobile terminal (third mobile terminal) corresponding to the changed terminal information (e.g., third mobile terminal information).
Thereafter, referring to
Thereafter, the second mobile terminal 200 and the UAV 1000 may be connected to each other to perform wireless communication. At this time, the connection between the UAV 1000 and the first mobile terminal 100 may be cut off, and the controller 180 of the UAV 1000 may periodically transmit a signal requesting connection to the first mobile terminal.
When the control approval signal for the control request signal is received from the second mobile terminal 200, the controller 1180 of the UAV 1000 may control the wireless communication unit to connect with the second mobile terminal 200 to perform wireless communication (S440).
The controller 1180 of the UAV 1000 may perform a function corresponding to the control signal based on a control signal received from the second mobile terminal 200 instead of the first mobile terminal 100.
At this time, when the controller 1180 of the UAV 1000 may control the wing part 1210 so that flight is maintained at a point where the UAV is located at the time of transmitting the control request signal until the control approval signal is received. Here, maintaining flight of the UAV 1000 at one point may be referred to as hovering or a hovering mode (function, operation).
Specifically, when it is detected that the UAV enters a preset state in which it is impossible to control the UAV by the first mobile terminal 100, from a state that the UAV 1000 is connected to the first mobile terminal through wireless communication, the controller 1180 of the UAV 1000 may transmit the control request signal to the second mobile terminal 200. Here, the detection point and the point at which the control request signal is transmitted may be the same or may have a predetermined time difference.
When the control request signal is transmitted (or when it is detected that the UAV enters the preset state in which it is impossible to control the UAV), the controller 1180 may maintain flight at the flight point (position) at the transmission time (or detection time). The flight at the corresponding point may be maintained until a control approval signal is received.
Thereafter, in the present invention, referring to
For example, as illustrated in (a) of
Specifically, when the control request signal is received from the UAV 1000, the controller 180 of the second mobile terminal 200 may display screen information 500a corresponding to the control request signal on the display unit 151. Also, the controller 180 of the second mobile terminal 200 may control the communication unit to transmit the control approval signal for the control request signal to the UAV based on a user request.
When the control approval signal is transmitted, the communication unit may be connected to perform wireless communication with the UAV. In addition, screen information received from the UAV 1000 may be displayed on the display unit 151.
As illustrated in (b) of
When the UAV is connected to the second mobile terminal 200 different from the first mobile terminal 100 to perform wireless communication, the controller 1180 of the UAV 1000 may transmit a preview image 510 received through the camera 1121 of the UAV 1000 and at least one image 520 captured through the camera 1121 to the second mobile terminal 200.
In this case, the preview image 510 and the at least one image 520 received from the UAV 1000 may foe displayed on the display unit 151 of the second mobile terminal 200. The at least one image 520 may be an image captured in a state of being connected to the first mobile terminal 100 to perform wireless communication. The at least one image 520 may be displayed on or disappear from the display unit 151 based on applying of a predetermined type of touch (e.g., long touch, multi-touch, drag touch, double touch, etc.).
In the present invention, the UAV 1000 transmits an image (at least one image) captured in a state of being connected to the first mobile terminal 100 to perform wireless communication to the second mobile terminal 200, so that the user of the second mobile terminal 200 may easily recognize the captured image.
As described above, in the present invention, in a state that a control right for controlling the UAV is set in the first mobile terminal, when the first mobile terminal enters an uncontrollable state, a control method for setting a control right to the second mobile terminal different from the first mobile terminal in an optimized manner may be provided.
On the other hand, in the present invention, in addition to that the UAV 1000 enters the preset state (for example, the connected signal strength becomes weaker than the reference strength or a preset control signal related to the control is received from the mobile terminal), the mobile terminal capable of controlling the UAV 1000 may be changed (i.e., the control right may be changed to another terminal).
In a state that the first mobile terminal 100 and the UAV 1000 are connected to each other so that they may communicate wirelessly, a preview image received from the UAV 1000 and at least one terminal information capable of controlling the UAV 1000 may be displayed on the display unit 151 of the first mobile terminal 100 as illustrated in (a) of
When any one of the at least one terminal information is selected, the controller 180 of the first mobile terminal 100 may transmit the selected terminal information to the UAV 1000 so that the UAV may transmit a control request signal corresponding to the selected terminal information to the mobile terminal corresponding to the selected terminal information.
For example, as shown in (a) of
The icon 612 may be output to the display unit 151 based on selection of a graphic object 610 associated with an output function of the icon 612.
When any one icon 612a among the icons 612 is selected, the controller 180 of the first mobile terminal 100 may transmit the terminal information associated with the any one of the icon 612a to the UAV 1000.
The UAV 1000 may transmit a control request signal to the mobile terminal corresponding to the terminal information based on the terminal Information received from the first mobile terminal 100. For example, when the selected terminal information is the second mobile terminal information 200a, the controller 1180 of the UAV 1000 may transmit a control request signal to the second mobile terminal 200 corresponding to the second mobile terminal information 200a.
Screen information corresponding to the control request signal may be displayed on the display unit 151 of the second mobile terminal 200. Thereafter, when a control approval signal for the control request signal is received from the second mobile terminal 200, the UAV 1000 may be connected to perform wireless communication with the second mobile terminal 200. That is, the mobile terminal capable of controlling the UAV 1000 may be changed from the first mobile terminal 100 to the second mobile terminal 200.
At this time, when the UAV 1000 is connected to perform wireless communication with the mobile terminal (second mobile terminal) corresponding to the selected terminal information, the controller 1180 of the UAV 1000 may transmit notification information indicating that the mobile terminal capable of controlling the UAV 1000 has been changed, to a mobile terminal (for example, first to third mobile terminals) corresponding to at least one terminal information transmitted from the first mobile terminal 100.
Also, as shown in (c) of
Meanwhile, as the first mobile terminal 100 is first connected to the UAV 1000, the first mobile terminal 100 may be set as a master terminal. In this state, when the second mobile terminal information is received from the first mobile terminal 100, the communication unit of the UAV 1000 may transmit a control request signal to the second mobile terminal.
When the control approval signal is received from the second mobile terminal 200, the communication unit of the UAV 1000 may be connected to perform wireless communication with the second mobile terminal 200.
At this time, in a state that the UAV 1000 is connected to perform wireless communication with the second mobile terminal 200, when a control right request signal is received from the first mobile terminal 100, the controller 1180 of the UAV 1000 may release the connection to the second mobile terminal 200 and control the communication unit of the UAV so that the UAV may be connected to the first mobile terminal 100. That is, when the control right request signal is received from the first mobile terminal 100, the controller 1180 of the UAV may change the mobile terminal capable of controlling the UAV from the second mobile terminal 200 to the first mobile terminal 100.
In this case, when the control right request signal is received from the third mobile terminal 300 different from the first mobile terminal 100, the connection with the second mobile terminal 100 may be released based on an approval signal received from the second mobile terminal. On the other hand, the connection with the second mobile terminal may be released without the approval signal when the control right request signal is received from the first mobile terminal 100.
For example, when the second mobile terminal 200 (slave terminal) and the UAV 100 are connected to each other, the icon 620 associated with a function of requesting (withdrawing) a control right may be displayed on the display unit 151 of the first mobile terminal 100 (master terminal).
When the icon 820 is selected, the controller 180 of the first mobile terminal 100 may transmit a control right request (withdrawal) signal to the UAV 1000. In this case, based on the transmission of the control right request (withdrawal) signal from the first mobile terminal 100 as a master terminal, the controller 180 of the UAV 1000 may release the connection with the second mobile terminal 200 and may be connected to the first mobile terminal 100 (that is, the control right may be changed from the second mobile terminal to the first mobile terminal) although an approval signal of the second mobile terminal is not received.
In this case, as shown in (b) of
Meanwhile, in a state that the second mobile terminal 200 (slave terminal) and the UAV 100 are connected, a control right request signal from the third mobile terminal 300 (another slave terminal) is received to the UAV 1000. In this case, the controller 1180 of the UAV 1000 may transmit to the second mobile terminal 200 information indicating that the control right request signal has been received from the third mobile terminal 300. When an approval signal for the control right request signal is received from the second mobile terminal 200, the controller 180 of the UAV 1000 may release the connection with the second mobile terminal 200 and may be connected for wireless communication with the third mobile terminal 300.
Meanwhile, if the approval signal for the control right request signal is not received, the connection between the UAV 1000 and the second mobile terminal 200 may be maintained.
Meanwhile, in the present invention, the master terminal may be changed. For example, as shown in (a) of
As shown in (c) of
Through this configuration, the present invention may provide an optimized UI/UX that may change the mobile terminal that controls the UAV more conveniently.
Hereinafter, a method for landing a UAV related to the present invention will be described in more detail with reference to the accompanying drawings.
As illustrated in (a) of
When the icon 710 is selected, the controller 180 may be output map information 720 and a menu (or graphic object) 730 for selecting landing position information, to the display unit 151.
The map information 720 may include a graphic object 722 indicating a position of the UAV and a graphic object 724 indicating a position of the mobile terminal 100.
Also, the menu 730 may include preset landing position information, current position information of the mobile terminal 100, current position information of the UAV 1000, and the like, and may further include an item 730a for selecting position information by the user.
After the item 730a is selected, when a touch is applied to one point 740 of the map information displayed on the display unit 151 as shown in (c) of
Meanwhile, as illustrated in (a) of
More specifically, the controller 1180 of the UAV 1000 may transmit the notification information 800 to the mobile terminal 100 based on a case where a flight available distance according to an amount of the battery is shorter than a distance between the current UAV and a preset landing position information or a case where the flight available distance is shorter than a distance between the current UAV and the current mobile terminal.
When the notification information 800 is selected, map information 810, information 820 relating to the UAV, an icon 814 indicating a position of the UAV 1000, an icon 812 indicating a current position of the mobile terminal, and an icon 816 indicating preset landing position information may be displayed on the display unit 151 of the mobile terminal 100. Also, an indicator 830 for guiding a flight available range (or maximum range) of the UAV 1000 with respect to a current battery amount may foe displayed on the display unit 151. Also, an icon 860 capable of selecting an operation of the UAV 1000 may be displayed on the display unit 151.
The information 820b related to the UAV may include a distance (time) from the preset landing position information 820a and information 820b on a distance (time) from a current position of the UAV 1000 to a position corresponding to the landing position information.
In this state, when a touch is applied to one point in the indicator 830, the controller 180 may output a notification window 850 for guiding whether to change a landing position of the UAV to a position corresponding to the one point.
If the change for the landing position is accepted, the controller 180 may change a landing position of the UAV 1000 to a position corresponding to the one point and display an icon 816 for guiding the changed position at the one point, as shown in (c) of
Meanwhile, when the icon 860 is selected, a menu 862 associated with an operation of the UAV 1000 may be output on the display unit 151.
The menu 862 may include an item 862a associated with an operation of maintaining (hovering) flight at a point where the UAV 1000 is currently positioned, an item 862b associated with an operation of landing the UAV 1000 at a point where the UAV 1000 is currently located, and an item 862c associated with an operation of landing the UAV to a position corresponding to the landing position information, and the like.
After the landing position is changed, if the item 862c associated with the operation of landing to the position corresponding to the landing position information is selected among the stems, the controller 180 may transmit a control signal for landing to the changed position, to the UAV 1000.
Through the configuration, the present invention may provide a control method capable of landing the UAV in a more optimized manner.
A setting screen 900 for setting a specific function of an application related to control of the UAV 1000 may be displayed on the display unit 151 in the mobile terminal 100 according to the present invention. The setting screen 900 may be output based on a user request.
Also, the setting screen 900 may include an item 910a for selecting whether to output a preview image received from the UAV 1000, an item 910a for selecting whether to receive a control request signal from the UAV 1000, and an item 910c for selecting whether to receive at least one image captured while the UAV 1000 is being controlled by another mobile terminal in case where the UAV was controlled by the other mobile terminal and is currently controlled by the mobile terminal 100 (or in case where the mobile terminal controlling the UAV is changed from the other mobile terminal to the present mobile terminal).
As described above, the present invention may provide an optimized control method for controlling the UAV using the second mobile terminal different from the first mobile terminal, when a connection signal strength between the first mobile terminal controlling the UAV and the UAV becomes weak or when the first mobile terminal enters a state in which it is impossible to control the UAV.
Further, the present invention may provide a control method for selecting the second mobile terminal capable of controlling the UAV more stably by selecting the second mobile terminal based on not only the priority set by the user but also an image captured by the UAV, when the second mobile terminal different from the first mobile terminal is selected.
In addition, in the present invention, when the mobile terminal capable of controlling the UAV is changed from the first mobile terminal to the second mobile terminal, an image captured by the control of the first mobile terminal may be checked in the second mobile terminal. Accordingly, the user may more easily and simply recognize a previously photographed region and a region to be photographed in the future.
In addition, the present invention may provide a UI/UX capable of more simply changing a mobile terminal capable of controlling the UAV according to a user's request.
