DETAILED DESCRIPTION

The present application will be further described in detail in conjunction with the drawings and the embodiments. It is to be understood that the embodiments set forth below are only intended to illustrate the present application, rather than limiting the present application. Additionally, it is also to be noted that for ease of description, only part, not all, of structures related to the present application are illustrated in the drawings.


The embodiments of the present application provide a cinema chair control system. FIG. 1 is a structure diagram of a cinema chair control system according to an embodiment of the present application. With reference to FIG. 1, the cinema chair control system includes multiple near-end controllers 100, a gateway 300, and a first remote control apparatus 400.


The near-end controllers 100 are configured on cinema chairs 200. As shown in FIG. 2, each near-end controller 100 is configured with a communication module 110 and a drive module 120, and communication modules 110 may communicate with each other. The drive module 120 receives a control instruction sent from the communication module 110 to control the cinema chair 200. As shown in FIG. 3, each cinema chair 200 may be considered as one node, the nodes are connected to each other to form a mesh channel, and the control instruction may be freely transmitted in the mesh channel. The above communication is similar to a mesh networking function. The nodes can communicate with each other, and when the control instruction sent from the gateway 300 cannot cover the whole cinema hall, the control instruction may be forwarded through the nodes to ensure that the whole cinema hall can receive the complete instruction. The above communication also has a self-repair function, and when one of the nodes fails, the whole system may automatically preform re-networking. The near-end controller 100 may be considered as a cinema control box. For example, the control on the cinema chair 200 may be controlling the cinema chair 200 to adjust its angle, controlling the cinema chair to perform pressure induction to count a chair occupancy rate, or the like, which is not limited in the present application. For example, the angle of the cinema chair 200 includes a seatback angle, a cushion angle, a rotation angle, and the like, and an angle between a viewer and the screen of the cinema hall may be adjusted or a sitting posture of the viewer may be adjusted by angle adjustment.


In conjunction with FIGS. 1 and 2, the gateway 300 is in a communication connection with the communication module 110 in the near-end controller 100, and the gateway 300 is connected to the Ethernet. For example, the range covered by the gateway 300 is part or all of the chairs 200 within the cinema hall, then all the chairs 200 in the cinema hall form a private wireless local area network, communication may be performed between the gateway 300 and the chairs 200 and between the chairs 200, and the communication between the gateway 300 and the chairs 200 and the communication between the chairs 200 may be performed in a wired connection manner (for example, by a network cable) or in a wireless connection manner (for example, by wireless fidelity (Wi-Fi) or Bluetooth). In an embodiment, the communication is performed in a wireless communication manner, and such wireless communication adopts a cinema protocol such that the near-end controllers 100 can exchange data over the wireless connection. For example, the communication is implemented based on an nrf51832-based radio frequency (RF) wireless communication and a private communication protocol.


In an embodiment, the communication module may be a chip module in the related art, and the chip module may perform communications operations.


With continued reference to FIG. 1, the first remote control apparatus 400 sends a control instruction to the near-end controller 100 through the gateway 300. For example, the cinema chairs 200 access a cinema chair online platform through the gateway 300 so that all chairs 200 in the cinema hall can be connected to the network. For example, the first remote control apparatus 400 is a smart terminal such as a computer, a mobile phone, and a tablet computer. The smart terminal communicates with the gateway 300 in a wireless communication manner such as a Wi-Fi or Bluetooth connection or in a wired communication manner such as a network cable connection. The smart terminal is configured with a client (for example, a browser, a cinema application (APP) or a third-party APP), the control instruction is received through the interface of the client, and the control instruction is sent through the client. Thus, the status of the cinema chair 200 can be viewed and controlled through the client. In an embodiment, a master server 500 is further configured in the Ethernet, the objective of the master server 500 is to drive the near-end controller 100 in each cinema chair 200 to exchange data, and at the same time, the master server 500 is configured to send data and receive a command from an external device such as a smart terminal.


In an embodiment, the master server 500 may also be denoted as a server.


For example, a working process of the cinema chair control system is as follows: the gateway 300 and the communication modules of the near-end controllers 100 constitute a mesh channel, the first remote control apparatus 400 sends a control instruction to the gateway 300, the control instruction is transmitted in the mesh channel, and a communication module of at least one near-end controller 100 receives the control instruction to drive at least one cinema chair 200 to adjust the angle. It is to be understood that since the gateway 300 is connected to the Ethernet, status data of the cinema chairs 200 can be sent to the master server 500 and a cloud 600.


In summary, in the embodiment of the present application, the near-end controller 100 is configured on the cinema chair 200, the communication modules of the near-end controllers 100 can communicate with each other, the gateway 300 is set to be in a communication connection with the communication modules, the gateway 300 is connected to the Ethernet, and the first remote control apparatus 400 is set to be capable of sending the control instruction to the near-end controller 100 through the gateway 300. The setting of the gateway 300 and the setting of the communication module in the near-end controller 100 enable the cinema chair 200 to have a networking function for making the cinema chair 200 join a private network of all cinema chairs 200 in the cinema hall. The remote control apparatus such as a smart terminal may be locally driven through a switch configured within the cinema or may be remotely driven through the Ethernet or the like. Through the setting in the embodiment of the present application, the functions of the cinema chairs 200 are enriched, and the cinema chairs 200 can be interconnected with each other through a communication connection. The managing staff can adjust the cinema chairs collectively through the first remote control apparatus 400 with a one-button operation after viewers leave the cinema hall or before a movie starts, thereby reducing the labor strength of the managing staff.


With continued reference to FIG. 1, on the basis of the preceding embodiments, in an embodiment, the cinema chair control system further includes a second remote control apparatus 700. The second remote control apparatus 700 is in a communication connection with the communication modules 110 of the near-end controllers 100 and sends the control instruction to the communication modules 110 of the near-end controllers 100. For example, the second remote control apparatus 700 is a remote control or the like. Compared with the first remote control apparatus 400, the second remote control apparatus 700 such as a remote control has fewer functions and is unable to selectively control part of the cinema chairs 200 to perform angle adjustment through the network platform, but it can control the angles of all the cinema chairs 200 in the cinema hall to return to a default angle, thereby collectively adjusting the cinema chairs 200 in a simple and convenient manner and facilitating the operation of the managing staff.


On the basis of the preceding embodiments, in an embodiment, if a wireless communication manner is used for the connection between the gateway and the near-end controllers, the cinema chair control system further includes a wireless communication power amplifier to enhance communication strength between the gateway and the near-end controllers, thereby reducing transmission time of the control instruction and improve the working efficiency. Especially for a relatively large cinema hall, the setting of the wireless communication power amplifier can enable signals of the gateway to be transmitted over a further distance, thereby facilitating the connection between the gateway and more near-end controllers.


On the basis of the preceding embodiments, in an embodiment, the near-end controller further includes a call button. The call button is connected to the communication module of the near-end controller, and the communication module of the near-end controller transmits a call signal to the first remote control apparatus through the gateway. Through the above setting, working personnel may receive a call from a customer at a corresponding position through a reminder apparatus such as a display or an alarm of the first remote control apparatus and then make a rapid response to a problem and a service requirement raised by the customer during movie watching.


On the basis of the preceding embodiments, in an embodiment, the drive module includes a cushion inductive sensor. The cushion inductive sensor is configured to induce pressure to generate an induction signal, and the communication module of the near-end controller transmits the induction signal to the first remote control apparatus through the gateway. For example, after the cushion inductive sensor receives the control instruction, the cushion inductive sensor induces whether the chair is occupied and generates an induction signal, and the generated induction signal is transmitted to the first remote control apparatus through the communication module and the gateway. Through the above setting, working personnel may count an actual chair occupancy rate through the first remote control apparatus, and the actual number of viewers and the number of tickets sold can be counted.


In an embodiment, the drive module includes a human body detection device. For example, the human body detection device is a human body inductive cushion, and the human body inductive cushion may include the cushion inductive sensor.



FIG. 4 is a structure diagram of a drive module according to an embodiment of the present application. With reference to FIG. 4, on the basis of the preceding embodiments, in an embodiment, the drive module includes a single-chip microcomputer 121, a driver chip 122, a metal-oxide-semiconductor field-effect transistor (MOSFET) circuit 123 and a motor 124 that are connected in sequence. The driver chip 122 drives the MOSFET circuit 123. For example, the model of the driver chip 122 is vnh7100as. In the embodiment of the present application, the MOSFET circuit 123 is used to control the operating of the motor, instead of a relay. The MOSFET circuit 123 consists of a MOSFET, and compared with the relay, the MOSFET has a faster switch response speed and is in a silent state. Through the above setting, an operating voltage (or an operating speed) of the motor 124 can be better controlled, and the control process is performed in a muted manner. The driver chip 122 may acquire an operating current of the motor. When the motor 124 initiates, the driver chip 122 lowers an initiation voltage to make the motor 124 operate slowly, then the motor 124 operates at full speed, and a large current generated when the motor 124 just initiates can be avoided, thereby effectively reducing a burden on the power supply when the driver chip 122 initiates.



FIG. 5 is a structure diagram of another drive module according to an embodiment of the present application. With reference to FIG. 5, on the basis of the preceding embodiments, in an embodiment, the drive module further includes a ripple acquisition and amplification circuit 125. The ripple acquisition and amplification circuit 125 is serially connected between the motor 124 and the single-chip microcomputer 121. The ripple acquisition and amplification circuit 125 is configured to acquire and amplify a specific ripple generated during an operating process of the motor 124 and transmit the specific ripple to the single-chip microcomputer 121. The motor 124 generates specific ripple data for each operating circle. In the embodiment of the present application, the amplitude of the ripple generated by the motor 124 is amplified by the ripple acquisition and amplification circuit 125 such that the ripple can be acquired and computed by the single-chip microcomputer 121, and the number of ripples generated when the motor 124 operates over a specific distance is recorded to enable the motor 124 to have a position memory function. Therefore, when the motor 124 is controlled to operate over a specific distance, only the number of ripples needs to be controlled to match the specific distance, and no distance acquisition is needed, thereby reducing distance acquisition difficulty. Through the setting in the embodiment of the present application, the operating of the motor 124 can be accurately controlled by setting a new control algorithm and a control circuit.


In the preceding embodiments, the ripple acquisition and amplification circuit is set in a variety of manners. The setting of the ripple acquisition and amplification circuit is described below, which does not limit the present application.

An output terminal of the second amplification module 1253 is electrically connected to the single-chip microcomputer and outputs a signal M3Taks. Through the above setting, the acquisition and amplification of the signal M3shunt are achieved. For example, a waveform of the output signal M3Taks is a square wave with a voltage of 3.3 V, the number of pulses of the square wave corresponds to the number of ripples generated during the operating of the motor, and the voltage of 3.3 V may be recognized and calculated by the single-chip microcomputer.

It is to be noted that FIG. 6 exemplarily shows that two-stage amplification is performed on the signal M3shunt, which does not limit the present application. In other embodiments, the amplification stage may be set according to requirements.


On the basis of the preceding embodiments, in an embodiment, the cinema chair control system further includes a database including information related to all cinema chairs. The first remote control apparatus displays information to the working personnel according to the information in the database. For example, parameters of all near-end controllers are scanned periodically to obtain data and update the database. The database is thus kept up-to-date. The information in the database is set according to requirements to meet demands of different customers.


The embodiments of the present application further provide a cinema chair control method. The control method is applied to the cinema chair control system provided by any of the embodiments of the present application and is based on a cinema chair network platform. For example, the cinema chair network platform includes the hardware structure and/or the software program in the cinema chair control system. FIG. 7 is a flowchart of a cinema chair control method according to an embodiment of the present application. With reference to FIG. 7, the cinema chair control method includes S110, S120, and S130.


In S110, a mesh channel is constituted by a gateway and communication modules of near-end controllers.


The cinema chair control system has a networking function for making the cinema chairs join the private network of all cinema chairs in the cinema hall. In S120, a first remote control apparatus sends a control instruction to the gateway.


The control instruction of the first remote control apparatus may be generated according to playback progress of the movie or an operation of the working personnel. For example, when the movie is finished playing, the first remote control apparatus automatically generates a control instruction. Alternatively, the control instruction typed by a user is received through an interface of a client of the first remote control apparatus.


In S130, the control instruction is transmitted in the mesh channel, and a communication module of at least one near-end controller receives the control instruction to control a cinema chair.


In the embodiment of the present application, based on the cinema chair network platform, the first remote control apparatus sends the control instruction to the gateway, the control instruction is transmitted in the mesh channel, and the communication module of at least one near-end controller receives the control instruction to control the cinema chair. Through the setting in the embodiment of the present application, the function of the cinema chair is enriched, and the cinema chairs can be interconnected with each other through a communication connection. The control on the cinema chair may be controlling the cinema chair 200 to adjust its angle, controlling the cinema chair to perform pressure induction to count the chair occupancy rate, or the like, which is not limited in the present application. For example, the managing staff may adjust the cinema chairs collectively through the first remote control apparatus with a one-button operation after viewers leave the cinema hall or before a movie starts, thereby reducing the labor strength of the managing staff. Alternatively, the working personnel can count the actual chair occupancy rate through the first remote control apparatus to count the actual number of viewers and the number of tickets sold.


On the basis of the preceding embodiments, in an embodiment, the cinema chair control method further includes that a second remote control apparatus sends the control instruction to the communication modules of the near-end controllers to enable all the drive modules to drive all the cinema chairs to perform angle adjustment. Compared with the first remote control apparatus, the second remote control apparatus such as a remote control has fewer functions and is unable to selectively control part of the cinema chairs to perform angle adjustment through the network platform, but it can control angles of all the cinema chairs in the cinema hall to return to the default angle, thereby collectively adjusting the cinema chairs in a simple and convenient manner and facilitating the operation of the managing staff.


On the basis of the preceding embodiments, in an embodiment, the transmission of the control instruction in the communication modules of the near-end controllers includes modifying a communication parameter to enable the control instruction to be transmitted through a channel whose data packet loss rate is less than a preset value. The preset value may be, for example, one thousandth to five thousandths, and the value is small enough to make the channel whose data packet loss rate is less than the preset value be considered as the idlest channel. The communication parameter may be freely modified, and through the above setting, the communication efficiency is improved, thereby facilitating the rapid response of the cinema chair.


On the basis of the preceding embodiments, in an embodiment, the step in which the control instruction is transmitted through the channel whose data packet loss rate is less than the preset value includes the following: if a data packet loss rate of the current channel within at least two frames for transmitting the control instruction is greater than the preset value, the communication parameter is modified, and the channel for transmitting the control instruction is changed; otherwise, the current channel is maintained to transmit the control instruction. For example, there are ten channels available for transmitting the control instruction, and the control instruction is transmitted through one of these channels. Within one hundred frames, the data packet loss rate for transmitting the received control instruction is less than one thousandth, or even if no data packet loss occurs, the current channel is considered as the idlest channel, and the current channel continues being used for transmitting the control instruction. If the data packet loss rate of the received control instruction is greater than one thousandth, the current channel is not considered as the idlest channel, and another channel is selected for transmitting the control instruction by automatically modifying the communication parameter. The communication parameter may be automatically modified in a variety of manners. For example, channel re-selection is achieved by adding 1 to the channel serial number. Through the setting in the embodiment of the present application, the channel selection and the transmission of the control instruction are achieved by automatic trial and error so that the control instruction can be transmitted through the idlest channel, thereby enhancing the communication efficiency and facilitating the rapid response of the cinema chair.


On the basis of the preceding embodiments, in an embodiment, the transmission of the control instruction in the communication modules of the near-end controllers includes that multiple communication modules receive the control instruction and return feedback signals, respectively, and the multiple feedback signals are returned to the gateway at time intervals. For example, FIG. 8 is a schematic diagram of a communication slot according to an embodiment of the present application. FIG. 8 exemplarily illustrates slot0, slot1, slot2, and slot3. In a transmission process of the control instruction, the gateway transmits the control instruction to the communication module of a closer cinema chair in slot0, the communication module of the closer cinema chair transmits the control instruction to the control module of a farther cinema chair, and so on. After the communication module of the cinema chair receives the control instruction, the communication module gives feedback to the node (the communication module of another cinema chair or the gateway) sending the control instruction, a feedback signal is sent to the node, and the feedback signal is then returned through a reverse sending path of the control instruction. In the embodiment of the present application, a time interval is set for the feedback signals returning to the gateway to prevent the feedback signals from being blocked at the location of the gateway node, thereby enhancing smoothness of the channel for transmitting the control instruction and the feedback signal.


In an embodiment, the time interval may be set to 10 ms+random number, and for example, the random number is 1 ms to 10 ms. Through the above setting, the smoothness of the transmission channel can be guaranteed, and a network delay caused by an excessively long waiting time of the feedback signals can be avoided.


On the basis of the preceding embodiments, in an embodiment, the cinema chair control method further includes the following: if a near-end controller fails, the communication module of the near-end controller sends a fault signal to the first remote control apparatus through the gateway. A failure of the near-end controller may be, for example, motor stalling and a sudden increase in current. Since the motor stalling may cause a change in the operating parameter, a failure of the motor is determined. For example, when the motor is in poor contact or is blocked by an external force, the motor stalls, and the current suddenly increases. An anti-clamping function may also be achieved by sending the fault signal. When a hand of a movie viewer is clamped, the current suddenly increases, a fault signal is generated, and the first remote control apparatus may send the control instruction according to the fault signal to control the motor to be powered off, thereby preventing the hand from being clamped. Through the above setting, once the chair fails, the working personnel can be notified timely, thereby facilitating timely maintenance and treatment.


On the basis of the preceding embodiments, in an embodiment, the cinema chair control method further includes the following: after a call signal of a near-end controller is triggered, the communication module of the near-end controller sends the call signal to the first remote control apparatus through the gateway.

Embodiment Two


FIG. 10 is a structure diagram of a motorized chair system according to embodiment two of the present application. In the embodiment, the cinema motorized chair parameter can be controlled, and the motorized chair system includes an upper computer 201, a server 500, a gateway 300, and a motorized chair 200.


The upper computer 201 is in a communication connection with the server 500 and is configured to receive a motorized chair control operation, send a control instruction corresponding to the motorized chair control operation to the server 500, and receive and display a motorized chair working parameter sent from the server 500. The server 500 is in a communication connection with the gateway 300 and is configured to send the control instruction to the gateway 300 and receive the motorized chair working parameter sent from the gateway 300. The gateway 300 is in a wireless connection with the motorized chair 200 and is configured to send the control instruction to the motorized chair 200 and forward the motorized chair working parameter to the server 500.


The upper computer 201 may be a web page, a computer application, a mobile phone application or a tablet application, which is not limited in the embodiment and may be flexibly set by those skilled in the art according to requirements. The upper computer 201 may be used for controlling a single motorized chair, part of the motorized chairs, or all the motorized chairs in the cinema hall. The motorized chair working parameter may be information such as an unfolding angle of each structure, a seat occupancy rate, and a chair serial number. For example, the motorized chair system has a built-in function such as overcurrent detection and stroke detection and is configured to obtain working parameter information of the motorized chair and send the working parameter information of the motorized chair to the gateway 300 by using a preset timing function. The gateway summarizes working parameter information of the motorized chairs in the cinema hall and sends the summarized working parameter information to the server 500. The server 500 forwards the working parameter information to the upper computer 201 and displays the working parameter information of the motorized chair by using an external display device. The display device may be a display screen.


The upper computer 201 further includes a permission system which may provide the corresponding function according to a level of a user login account.


The gateway 300 may include a Raspberry Pi 2.4G radio frequency (RF) wireless dongle, and the gateway 300 and the dongle communicate with each other through a universal serial bus (USB) serial port. For example, the gateway 300 may be manually configured with a signal channel and a signal address. The gateway 300 may be connected to the server 500 by means of a wired signal or a wireless signal. The gateway 300 may also be connected to the motorized chair 200 in a wireless connection manner such as a Wi-Fi, ZigBee protocol, and Bluetooth connection for assigning a chair serial number to the motorized chair. The gateway may be installed at a suitable location in the cinema hall according to requirements so that 2.4G RF signals can cover all the motorized chairs. The 2.4G technology may be implemented by a new mobile phone smart card that has an internally integrated 2.4G RF communication module and also includes functions of an ordinary smart card.


In one embodiment, the motorized chair control operation includes any operation performed by the user on the motorized chair. For example, through the second control signal corresponding to the wire control switch signal, the drive motor is controlled to drive the motorized chair to perform actions such as seatback adjustment, chair unfolding, and chair armrest extension and contraction, or the peripheral device is controlled to perform actions such as the heating cushion performs heating, the motor massage performs massage, and the like.


In an embodiment, the motorized chair system further includes a remote control 701. The remote control 701 is configured to configure wireless module information of the gateway and the motorized chair and complete a pairing connection with the gateway and the motorized chair based on the wireless module information. A key panel of the remote control may include multiple control buttons and a liquid crystal display screen, and the managing staff may perform an operation on the remote control 701. The remote control 701 may be used for controlling a single motorized chair, part of the motorized chairs, or all the motorized chairs in the cinema hall to be unfolded or folded.


In an embodiment, the upper computer 201 may be denoted as the first remote control apparatus 400.


In an embodiment, the gateway 300, the remote control, and the motorized chair 200 may communicate with each other via 2.4G RF wireless communication and may be configured to the same signal channel and the same address. The motorized chair 200 and the gateway 300 are set to be in a pairing state, and the remote control 701 is configured to send a pairing instruction and pairing information. The motorized chair 200 and the gateway 300 receive a pairing signal, then change their own signal channels and addresses, return a signal of successful pairing to the remote control 701, and then exit the pairing state.


In an embodiment, the remote control 701 of the motorized chair system also has a sniff function. If the remote control 701 is damaged and needs to be replaced, the signal channel and address of the motorized chair 200 or the signal channel and address of the gateway 300 may still be obtained through the sniff function without re-pairing all the motorized chairs with the gateway. FIG. 11 shows a flowchart of a remote control using a sniff function. As shown in FIG. 11, a slave or the host may exit the sniff mode when the time for the slave or the host being in the sniff mode exceeds a preset time. When the slave (the near-end controller or the gateway) receives a sniff instruction sent from the host (the remote control), the slave may feed back its own 2.4G RF wireless communication information including its channel and address, etc. When the host (the remote control) successfully obtains the 2.4G RF wireless communication information of the slave, the host changes its own original 2.4G RF wireless communication information to the obtained 2.4G RF wireless communication information and saves the new 2.4G RF wireless communication information. After the new 2.4G RF wireless communication information is successfully saved, the host and the slave exit the sniff mode at the same time. If the host does not obtain the 2.4G RF wireless communication information of the slave within a preset obtaining time, the host considers the slave being in a timeout state, and then the host still uses the last obtained 2.4G RF wireless communication information.


In an embodiment, the motorized chair system further includes a wireless communication power amplifier. The wireless communication power amplifier is configured to enhance communication strength between the gateway 300 and the motorized chair 200 to reduce the transmission time of the control instruction, thereby improving the working efficiency. Especially for a relatively large cinema hall, the setting of the wireless communication power amplifier can enable the signal of the gateway to be transmitted over a further distance, thereby facilitating the enhancement of the signal of the gateway.


In an embodiment, the motorized chair system further includes a call device. The call device is configured to transmit a call signal to the upper computer 201. The advantage of the setting is that the user can send an alert to the working personnel through the call device when encountering a problem so that the problem faced by the user during movie watching can be solved timely.


In an embodiment, the call device may be a call button configured in the near-end controller.


In the embodiment, the present application can be used to solve the problem in which the motorized chair in the related art is limited in function, and can neither automatically sense the seating information of the human body nor execute the corresponding control actions, thereby implementing the control function on the motorized chair, improving the user experience, and improving the intelligence of the motorized chair.


The present application provides a motorized chair and system to implement the control function on the motorized chair, enrich the function diversity of the motorized chair, improve user experience, and improve the intelligence of the motorized chair.
