The present disclosure relates to the field of communication and, more specifically, to a method and a device for automatic pairing.
Current mobile terminals (e.g., mobile phones, tablets, etc.) include a variety of features including image capturing, etc. As an auxiliary device to the mobile terminals, a handheld gimbal may provide a stable image capturing condition for the mobile terminals and may also provide a variety of control functions for the mobile terminals to facilitate user operations. To control the mobile terminal through the handheld gimbal, a reliable communication connection needs to be established between the handheld gimbal and the mobile terminal. Conventional communication connections between the handheld gimbal and the mobile terminal are mainly established a wired connection and a wireless connection.
However, the wired connection requires the use of a wire to connect the mobile terminal and the gimbal, which can be a cumbersome task. The wire may get tangled easily and bring inconvenience to the user. Further, the wireless connection between the mobile terminal and the gimbal also requires a complicated configuration and pairing process. For example, the user needs to adjust the mobile terminal and the gimbal to a pairable state respectively, then connect the mobile terminal with the gimbal, and then open an application on the mobile terminal that controls the gimbal to begin the interaction between the mobile terminal and the gimbal. This series of steps is cumbersome and time consuming, and not every user is able to successfully pair the mobile terminal with the gimbal.
One aspect of the present disclosure provides a method for an automatic pairing of a first device with a second device. The method includes identifying the second device using a first communication method and establishing a pairing relationship with the identified second device using a second communication method. The second communication method has a larger communication range than the first communication method.
Another aspect of the present disclosure provides a first device for automatically pairing with a second device. The first device includes a first communication component configured for a first communication method; a second communication component configured for a second communication method; and a processor. The processor is configured to perform: identifying the second device via the first communication component using the first communication method; and establishing a pairing relationship with the identified second device using the second communication method via the second communication component. The second communication method has a larger communication range than the first communication method.
For a more complete understanding of the present disclosure and its advantages, reference is now made to the following description taken in conjunction with the accompanying drawings, in which:
The exemplary embodiments of the present disclosure will be described below in conjunction with the accompanying drawings, other aspects, advantages and salient features of the present disclosure will be become apparent to those skilled in the art.
In the present disclosure, the terms “include” and “comprise,” as well as derivatives thereof, mean inclusion without limitation.
In the present disclosure, various embodiments are merely used to describe the principle of the present disclosure and should not be construed as limiting the scope of the present disclosure. Further, the following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness. Furthermore, throughout the drawings, the same reference numerals are used for the same or similar functions and operations.
Before describing the embodiments of the present disclosure in detail, the meaning of some of the technical terms used in the present disclosure will be explained first.
Near field communication (NFC), which is also called as a short-range wireless communication, is a short-range high frequency wireless communication technology that allows electronic devices to perform contactless point-to-point data transmission to exchange data within a short distance such as 10 cm (3.9 inches). The technology evolved from the contactless Radio Frequency Identification (RFID) technology and was developed by Philips Semiconductors (now NXP Semiconductors), Nokia, and Sony on the basis of RFID and interconnect technologies. NFC is a short-range high frequency radio technology that operates at 13.56 MHz within 10 cm with three transmission rates at 106 Kbit/s, 212 Kbit/s and 424 Kbit/s. At present, NFC has become the ISO/IEC IS 18092 international standard, the EMCA-340 standard and the ETSI TS 102 190 standard, and devices that support NFC can use both the active and passive read modes.
Bluetooth (BT) is a wireless technology standard that allows fixed and portable devices to exchange data over a short distance to form a Personal Area Network (PAN). BT uses Ultra High Frequency (UHF) radio wave to communicate via the 2.4 to 2.85 GHz ISM band. This technology was developed by Ericsson in 1994, and it was originally designed to create a wireless alternative of the RS-232 data cables. BT can connect to multiple devices to overcome synchronization problems.
The present disclosure provides a technical solution that allows a handheld gimbal and a mobile terminal (e.g., a mobile phone, a tablet, etc.) to quickly identify and pair with each other. Various embodiments may allow two devices to mutually determine the presence of each other and the identity of the other device using a first communication method, including a first communication technology having a smaller communication range (e.g., NFC, RFID, etc.), then a second communication method, including a second communication technology having a relatively larger communication range. Higher transmission speed (e.g., Bluetooth, Wi-Fi, etc.) may be used to establish a communication connection or pairing relationship based on the identified information (e.g., an identifier of the other device, the network address, etc.) to facilitate the interactions (e.g., control, data transfer, etc.) between the two devices. Hence, using the first communication technology with a smaller communication range, most of the other devices that may cause interference within the communication range of the second communication technology may be excluded, so the devices that need to be paired may be quickly identified. Subsequently, a communication connection between the two (or more) devices may be established using the second communication technology with larger communication range and higher communication rate.
It should be noted, however, that although in the following embodiments of the present disclosure, the description has been made by taking a handheld gimbal and a mobile terminal as an example, the present disclosure is not limited thereto. In fact, the present disclosure is also applicable to pair between various devices. For example, both devices can be mobile terminals, or both devices can be fixed devices or devices that move relatively infrequently. In fact, the technical solution provided in the present disclosure can be employed between any two or more devices that support two different communication technologies.
Further, although in the following embodiments of the present disclosure, the description is made using the distance as an example of the communication range, the concept of the communication range is not limited thereto. In fact, the present disclosure is also applicable to communication technologies having different communication frequencies, transmission powers, communication rates, etc. For example, the first communication technology may be a communication technology with a narrower communication band, and the second communication technology may be a communication technology with a wider communication band. In this case, using the communication technology with the narrow communication band, relatively fewer connection candidates can be determined in the relatively narrow communication band, so a connection target can be quickly identified, then the second communication technology with the wider communication band may be used to establish a communication connection with higher transmission rate and wider range to enable to pairing between devices.
Hereinafter, the first device of the present invention will be described in detail with reference to
As shown in
As shown in
In the embodiment shown in
As shown in
It can be understood that a device identification module is not limited to the NFC area 111 and may be other modules such as a RFID module.
Although not shown in
Next, a schematic diagram of a mobile phone having an NFC function will be described in detail with reference to
As shown in
In one embodiment of the present disclosure, the transmission of the identity information may be active or passive. For example, the NFC chip 210 of the mobile phone 200 may periodically transmit its identity information to indicate its presence to the surrounding NFC devices. In another example, the NFC chip 210 may transmit its own identity information in response to a query (e.g., polling, broadcasting) message from other NFC devices.
When the NFC chip 113 of the handheld gimbal 100 detects the identity information from the mobile phone 200, a Bluetooth module (not shown) of the handheld gimbal 100 can establish a Bluetooth communication connection with the mobile phone 200 based on the identity information of the mobile phone 200, and thereby achieving a quick pairing relationship between the handheld gimbal 100 and the mobile phone 200.
The Bluetooth module of the handheld gimbal 100 may be in a constant working state to find a connectable device. Or, the Bluetooth module of the handheld gimbal 100 may be triggered to start working when the handheld gimbal 100 detects the identity information of the mobile phone 200, so the Bluetooth module may not be activated before the identity information of the connectable mobile phone 200 is acquired, thereby reducing power consumption.
In some embodiments, after the handheld gimbal 100 establishes a pairing relationship with the mobile phone 200, the handheld gimbal 100 may automatically trigger an opening of an operation interface on the mobile phone 200, such as, but not limited to, the operation interface of the camera application. In other embodiments, after the handheld gimbal 100 establishes a pairing relationship with the mobile phone 200, the mobile phone 200 can also automatically open an operation interface thereon, such as, but not limited to, the operation interface of the camera application without the triggering from the handheld gimbal 100.
The structures of the handheld PTZ assembly 100 and the mobile phone 200 according to the embodiments of the present disclosure have been described in detail with reference to
