In order to more accurately realize function control on the back splint side, the application provides a control circuit on the back splint side, and referring to fig. 5, fig. 5 exemplarily provides a schematic diagram of a control circuit on the back splint side in an embodiment of the application.

Data transmission is carried out between the terminal and the back clip, and in the embodiment of the application, the terminal is connected with the back clip in a working environment, and the implementation mode of function control provided by the application is realized based on the connected terminal and the back clip; therefore, the present application provides a schematic diagram of an overall control circuit for connecting a terminal and a back clip, and refers to fig. 6 to implement a function control method based on the overall control circuit shown in fig. 6.

Referring to fig. 7, fig. 7 exemplarily provides a flowchart of a specific implementation manner of function control in an embodiment of the present application, where the method includes:

and S700, the terminal is successfully connected with the back clip.

In the embodiment of the application, data interaction can be carried out between the terminal and the back clip only after the terminal is successfully connected with the back clip. Therefore, the terminal and the back clip should be guaranteed to be successfully connected before the terminal sends a control command to at least one entity component in the back clip and/or receives data information associated with at least one entity component sent by the back clip.

In step S701, the terminal sends a control command to at least one entity component in the back clip.

Step S702, after receiving a control command sent by the terminal for at least one entity component, the back clip transmits data information associated with the at least one entity component to the terminal.

Illustratively, a terminal sends a radio frequency tag reading instruction to a radio frequency identification component in a back splint, and after receiving the radio frequency tag reading instruction sent by the terminal, the back splint acquires tag data through the radio frequency identification component and transmits the acquired tag data to the terminal;

the terminal sends a positioning data reading instruction to a positioning component in the back clip, and the back clip acquires positioning data through the positioning component after receiving the positioning data reading instruction sent by the terminal and transmits the acquired positioning data to the terminal.

Similarly, the above manner can be adopted for other solid components in the back clip, and the details are not repeated herein.

Step S703, when the back-end determines that the back-end meets the data transmission condition associated with the at least one entity component, transmitting the data information associated with the at least one entity component to the terminal.

Illustratively, when monitoring that the concentration of the gas acquired by the gas detection component reaches a concentration threshold value, the back clip determines that a data transmission condition associated with the gas detection component is met, and sends an interrupt notification to the terminal;

transmitting the connection state of the Bluetooth headset determined by the Bluetooth component connected with the talkback component to the terminal in real time, wherein the connection state of the Bluetooth headset is used for representing whether the Bluetooth headset is accessed into the back splint or not;

regularly transmitting the label data acquired by the radio frequency identification component to a terminal;

and transmitting the positioning data acquired by the positioning component to the terminal at regular time.

Step S704, after receiving the data information, the terminal controls the working state of at least one functional device associated with the terminal based on the data information.

Exemplarily, after receiving a bluetooth headset access notification sent by a back clip, the terminal is controlled to be disconnected from the talkback component, so as to realize the talkback of the bluetooth headset; or the terminal receives a notice that the Bluetooth headset sent by the back clip is not accessed, and controls the microphone of the wired headset to be connected with the output end of the talkback component after monitoring the notice that the wired headset is accessed, and the microphone of the wired headset is connected with the input end of the talkback component so as to realize the talkback of the wired headset; or the terminal receives the notice that the Bluetooth headset sent by the back clip is not accessed, and controls the loudspeaker to be connected with the output end of the talkback component and the microphone to be connected with the input end of the talkback component after monitoring the notice that the wired headset is not accessed, so as to realize hands-free talkback.

For another example, after receiving the tag data returned by the folder, the terminal displays the tag data in the display unit.

For another example, after receiving the positioning data returned by the back clip, the terminal uploads the positioning data to the server.

In another example, after the terminal receives the interrupt notification, the terminal controls the current limiting unit to start the current limiting operation.

The contents described in steps S701 to S702 and step S703 are implemented in two ways, and may be executed independently or synchronously, or step S703 may be executed first and then step S701 to step S702 may be executed during the execution.

In step S700, in order to ensure that the terminal is successfully connected to the back clip and the connection accuracy is ensured, a method for determining that the terminal is successfully connected to the back clip is provided in this embodiment of the present application, and referring to fig. 8, fig. 8 exemplarily provides a flowchart of a method for determining that the terminal is successfully connected to the back clip in this embodiment of the present application.

Step S800, after the terminal monitors a terminal startup instruction, an interface for monitoring a back clip access identification signal is set to be in an input pull-down state.

The interface for monitoring the back splint access identification signal is a DET monitoring interface, and the back splint access identification signal between the back splint and the back splint is set to be in an input pull-down state at the moment, wherein the input pull-down state indicates that the monitoring interface inputs low level under the default condition.

In a possible implementation manner, after the terminal monitors a terminal power-on instruction, except that the back clip access identification signal is set to be in an input pull-down state, other signals are set to be in an output low level through the processor, so that the outer leakage contact is prevented from being electrified.

Step S801, after the back clip monitors a back clip power-on instruction, the back clip of the connection terminal is connected to the interface of the identification signal, and is set to output a high level.

Wherein, the interface of the back clip access identification signal of the connecting terminal is a GPIO2 output interface.

In the embodiment of the application, after the power-on detection component of the back clip detects that the power-on key of the back clip is pressed, the detected power-on instruction of the back clip is confirmed, and the power-on instruction of the back clip is transmitted to the power management component of the back clip, after the power management component receives the power-on instruction of the back clip, power is supplied to the back clip controller, and at the moment, the back clip controller enters a working state.

When the back clip controller enters the working state, the controller configures each interface signal to control and manage the working state of each entity component in the back clip.

Illustratively, besides setting the GPIO2 output interface for connecting the folder access identification signal of the terminal to output high level, each entity component in the folder is controlled and managed according to a default mode:

configuring the GPIO6 output interface enabled by the radio frequency identification component to output low level so as to control the radio frequency identification component in the back clip not to start;

configuring the GPIO3 output interface enabled by the talkback component to output low level so as to control the talkback component in the back clip not to be started;

starting a positioning component through a TXD3 interface and an RXD3 interface to enable the positioning component to be in a working state and obtain positioning data;

initializing an ADC (analog to digital converter) channel for gas transmission, starting a gas detection component, enabling the gas detection component to be in a working state, and detecting the concentration of gas;

the bluetooth enable (BT _ EN) interface is set to output low to control the bluetooth feature in the back clip not to activate.

Step S802, the back clip sends back clip access notice to the terminal.

Illustratively, the back clip sends a high-level signal to the DET monitoring interface of the terminal through the GPIO2 output interface, that is, the back clip sends a back clip access notification to the terminal.

Step S803, after receiving the folder access notification, the terminal determines that there is folder access.

For example, after monitoring a high level input through the DET monitoring interface, the terminal confirms that a back-clip access notification sent by the back clip is received, and determines that the back clip is accessed.

Step S804, the terminal configures and initializes a communication interface with the folder. Wherein, the communication interface is a UART communication interface.

In step S805, the terminal sends a handshake packet to the folder through the communication interface.

Illustratively, the terminal sends the handshake packet to the back-clip through a TXD interface in the UART communication interface.

Step 806, after receiving the handshake data packet sent by the terminal, the back clip feeds back a handshake response data packet to the terminal.

For example, after receiving the handshake data packet sent by the terminal through the RXD0 interface in the UART communication interface, the back splint feeds back a handshake response data packet to the terminal through the TXD0 interface in the UART communication interface.

And step S807, after receiving the handshake response data packet sent by the back clip, the terminal determines to complete the identification and configuration with the back clip.

Illustratively, the terminal receives a handshake response data packet sent by the back clip through an RXD interface in the UART communication interface.

At this time, the terminal and the back clip are successfully accessed, and the terminal can send any instruction to the back clip and receive data information sent by the back clip so as to call at least one entity component in the back clip to realize a corresponding extended function.

In the embodiment of the present application, the back clip includes an intercom component, a radio frequency identification component, a gas detection component, a positioning component, a bluetooth component, and the like, and different physical components are controlled in different manners.

In order to realize accurate control for each entity component, in the embodiment of the application, a set of interaction command packet and data format packet of the terminal and the back folder is customized, so that after the controller of the back folder receives data sent by the terminal, the received data is identified according to the appointed interaction command packet and data format packet, which entity component is controlled is determined, and then distribution and corresponding control are performed on the entity component.

The following embodiments are described in detail with respect to specific implementations of control of each physical component.

Firstly, a control flow of a radio frequency identification function:

referring to fig. 9, fig. 9 exemplarily provides a control flow diagram of an rfid function in an embodiment of the present application, including the following steps:

and step S900, after monitoring that the RFID APK application installed on the terminal is started, the terminal sends a radio frequency identification component starting instruction to the back clamp.

Illustratively, the terminal sends the rfid component start instruction to the back-clip through the TXD interface in the UART communication interface.

In step S901, after the back clip receives a radio frequency identification component start instruction sent by the terminal, the back clip starts the radio frequency identification component.

For example, the controller of the back clip receives a radio frequency identification component start instruction sent by the terminal through an RXD0 interface in the UART communication interface, identifies the radio frequency identification component start instruction, and sets the GPIO6 output interface to output a high level to start the radio frequency identification component after determining that the command is a command for controlling the radio frequency identification component, that is, the radio frequency identification component is in an on state to wait for reading the radio frequency identification tag.

It should be noted that, the back cover may also start the rfid component when the back cover is powered on, and at this time, the steps S900 to S901 do not need to be executed.

Step S902, the back clip feeds back a radio frequency identification component start notification to the terminal to notify that the radio frequency identification component of the terminal has been started successfully.

Illustratively, the controller of the back clip feeds back the rfid component activation notification to the terminal via the TXD0 interface in the UART communication interface.

And step S903, after receiving the starting notice of the radio frequency identification component, the terminal sends a radio frequency tag reading instruction to the back clamp.

Illustratively, the terminal receives a radio frequency identification component start notification through an RXD interface in the UART communication interface; and after monitoring the pressing operation of a soft key for reading the tag in the RFID APK application, the terminal sends a radio frequency tag reading instruction to the controller of the back clamp through a TXD interface in the UART communication interface.

Step S904, after receiving the rf tag reading instruction sent by the terminal, the back clip obtains tag data.

For example, the controller of the back-pack receives a radio frequency tag reading instruction sent by the terminal through an RXD0 interface in the UART communication interface, identifies the radio frequency tag reading instruction, and after determining that the radio frequency tag reading instruction is an instruction for controlling the radio frequency identification component, the controller of the back-pack distributes the radio frequency tag reading instruction to the radio frequency identification component through a TXD2 interface, so that the radio frequency identification component acquires tag data.

And step S905, the back clip feeds the acquired tag data back to the terminal.

Illustratively, the controller of the back clip receives the tag data acquired by the rfid component via the RXD2 interface, and then the controller feeds the tag data back to the terminal.

Step S906, after receiving the tag data, the terminal displays the tag data in the display unit.

Illustratively, the terminal receives the tag data through an RXD interface in the UART communication interface.

Secondly, a control flow of the positioning function:

referring to fig. 10, fig. 10 exemplarily provides a control flow diagram of a positioning function in an embodiment of the present application, including the following steps:

and step S1000, the terminal sends a positioning data reading instruction to the back clip.

For example, the mobile terminal sends the positioning data reading instruction to the back clip through the TXD interface in the UART communication interface at regular time.

Step S1001, after the back clip receives a positioning data reading instruction sent by the terminal, positioning data is obtained.

For example, the controller of the back splint receives a positioning data reading instruction sent by the terminal through an RXD0 interface in the UART communication interface, recognizes the positioning data reading instruction, and after determining that the positioning data reading instruction is an instruction for controlling the positioning component, the controller of the back splint distributes the positioning data reading instruction to the positioning component through a TXD3 interface, so that the positioning component acquires the positioning data.

It should be noted that the positioning component is already set to the activated state according to the default mode when the back clip is powered on. In another possible implementation manner, the positioning component may also be activated together with the rfid component after receiving an activation instruction sent by the terminal.

And step S1002, the back clip feeds back the acquired positioning data to the terminal.

For example, the controller of the back clip receives the positioning data acquired by the positioning component through RXD3, and then the controller feeds back the positioning data to the terminal through TXD0 interface in the UART communication interface.

And step S1003, the terminal reports the positioning data to the server.

Illustratively, the terminal receives the positioning data through a TXD interface in the UART communication interface, and reports the positioning data to the server in time when receiving the positioning data; or periodically reporting the received positioning data to the server.

The positioning data is accurate positioning information obtained through an RTK positioning mode, the accurate positioning information is reported to the server, the position information of the detecting personnel can be accurately monitored in real time, the emergency positioning rescue effect is achieved, and the safety of the detecting personnel is guaranteed.

In a possible implementation manner, the back clip can feed back the positioning data to the terminal at regular time without instruction triggering of the terminal.

Thirdly, a control flow of the gas detection function:

referring to fig. 11, fig. 11 is a control flow chart for providing a gas detection function in the embodiment of the present application, including the following steps:

step S1100, the back clip detects the gas concentration.

Illustratively, the controller of the back clip acquires the gas concentration detected by the gas detection component through the ADC interface.

It should be noted that the gas detection component may be started in a default mode when the back clip is started; the back clip may be activated after receiving an opening instruction for the gas detection unit sent from the terminal.

In step S1101, the back clip compares the detected gas concentration with a preset concentration threshold.

Step S1102, when it is determined that the monitored gas concentration exceeds the concentration threshold, the back clip sends an interrupt notification to the terminal.

Illustratively, when the controller of the back clip determines that the monitored gas concentration exceeds the concentration threshold, an interrupt notification is sent to the terminal through the GPIO1 output interface.

Step S1103, after receiving the interrupt notification sent by the back clip, the terminal controls the current limiting unit to start current limiting operation.

In a possible implementation manner, the interruption notification carries warning information that the gas concentration exceeds the concentration threshold, and when the terminal determines that the interruption notification carries the warning information that the gas concentration exceeds the concentration threshold, the terminal controls the current limiting unit to start the current limiting operation.

In another possible implementation manner, after receiving the interrupt notification, the terminal sends interrupt source reading information to the back-clip through a TXD interface in the UART communication interface, and receives an alarm, which is returned by the back-clip and is caused by the gas concentration exceeding a concentration threshold, through an RXD interface in the UART communication interface, and then controls the current limiting unit to start current limiting operation.

In the application, the terminal controls the current limiting unit to start the current limiting operation, so that the current limiting unit works in a current limiting working state, the maximum power consumption of the terminal is limited, a flash lamp and high-power-consumption applications are limited, and the terminal works in an explosion-proof state.

In another implementation, the current limiting unit is placed in a normal operation mode when the terminal determines that the gas concentration does not exceed the concentration threshold.

It should be noted that, in the embodiment of the present application, the terminal may periodically send a gas concentration reading instruction to the back clamp, and when it is determined that the gas concentration exceeds the concentration threshold, the current limiting unit is controlled to start the current limiting operation; or, the back clip periodically sends the gas concentration to the terminal, and when the terminal determines that the gas concentration exceeds the concentration threshold, the current limiting unit is controlled to start the current limiting operation.

Fourthly, controlling the talkback function:

referring to fig. 12, fig. 12 is a control flow chart for providing an intercom function in the embodiment of the present application, including the following steps:

and step S1200, after monitoring that the talkback APK application installed on the terminal is started, the terminal sends a talkback component starting instruction to the back clip.

Illustratively, the terminal sends the talkback component start instruction to the back clip through a TXD interface in the UART communication interface.

In a possible implementation manner, after the terminal is successfully connected with the back clip, the terminal waits for public network communication or talkback voice, specifically, after the terminal monitors that the talkback APK application installed on the terminal is started, the terminal determines to enter the talkback voice, if the talkback APK application is not monitored to be started, the terminal switches an audio channel to a public network communication channel, and switches the audio to a corresponding channel according to the monitored connection state of the wired earphone and the bluetooth earphone.

And step S1201, after the back clip receives the talkback part starting instruction sent by the terminal, starting the talkback part and the Bluetooth part.

Illustratively, a controller of the back splint receives an intercom component starting instruction sent by a terminal through an RXD0 interface in a UART communication interface, identifies the intercom component starting instruction, and sets an output interface of a GPIO3 to output high level to start the intercom component after determining that the intercom component starting instruction is an instruction for controlling the intercom component, namely the intercom component is in an on state; meanwhile, BT _ EN is set to be high level so as to start the Bluetooth component, and the Bluetooth component is in a state of waiting for connection of the Bluetooth headset after being started.

It should be noted that, the back clip may also start the intercom component and the bluetooth component when the device is powered on, and at this time, the steps S1200 to S1201 do not need to be executed.

And step S1202, the back clip sends the connection state of the Bluetooth headset to the terminal.

Illustratively, the controller of the back splint transmits the connection state of the bluetooth headset determined by the bluetooth component connected with the intercom component to the terminal in real time through the TXD0 interface in the UART communication interface, so that the terminal controls the connection mode of the terminal and the intercom component, wherein the connection state of the bluetooth headset is used for representing whether the back splint has the bluetooth headset to be connected.

Step S1203, the terminal determines the earphone access condition based on the received connection status of the bluetooth earphone and the monitored wired earphone access status.

At this time, there are three access situations, namely bluetooth headset access, wired headset access, and no bluetooth headset or wired headset access, and the connection modes between the terminal and the intercom component are all different under the three access situations, which refer to steps S1204 to S1205 specifically.

And step S1204, the terminal monitors that the earphone is not accessed to notify, controls the loudspeaker to be connected with the output end of the talkback part of the back clip, and controls the microphone to be connected with the input end of the talkback part of the back clip.

The earphone is not accessed to inform the representation terminal that no wired earphone is accessed, and the back clip is not accessed to the Bluetooth earphone.

When the terminal does not monitor the access of the wired earphone and does not receive the notice of the back clip that the Bluetooth earphone is accessed or does not receive the notice of the back clip that the Bluetooth earphone is accessed, the speaker and the microphone of the terminal are adopted to realize the talkback voice.

At the moment, the terminal sets the output interface of the GPIO12 to output low level, controls the COM1 and NC1 in the analog switch U2 to be connected and controls the COM2 and NC2 to be connected; the GPIO10 is set to be high level, COM1 in the analog switch U1 is controlled to be connected with NO1, and COM2 is controlled to be connected with NO 2; at this time, the speaker of the terminal is switched to the output voice (AU _ OUT) path of the intercom component on the back clip for receiving the intercom voice. Meanwhile, the GPIO14 is set to be low level, the COM1 in the analog switch U2 is controlled to be connected with the NC1, and the COM2 is controlled to be connected with the NC 2; the GPIO11 is set to be high level, COM1 in the analog switch U6 is controlled to be connected with NO1, and COM2 is controlled to be connected with NO 2; at this time, the microphone of the terminal is switched to the audio input (AU _ IN) path of the intercom component on the back clip for sending the intercom voice. Referring to fig. 13, fig. 13 exemplarily provides a schematic diagram of a control circuit when a back clip implements a talk-back function through a speaker and a microphone in an embodiment of the present application.

And S1205, the terminal monitors the wired earphone access notification, and the Bluetooth earphone does not access the notification, so that the microphone of the wired earphone is controlled to be connected with the output end of the talkback part, and the microphone of the wired earphone is connected with the input end of the talkback part.

When the terminal monitors that the wired earphone is accessed, and does not receive the back clip to inform that the Bluetooth earphone is accessed, or receives the back clip to inform that the Bluetooth earphone is not accessed, the microphone and the microphone of the wired earphone are adopted to realize the talkback voice.

At the moment, the terminal sets the output interface of the GPIO12 to output high level, and controls the COM1 and the NO1 in the analog switch U2 to be connected and controls the COM2 and the NO2 to be connected; the GPIO13 is set to be high level, COM1 in the analog switch U3 is controlled to be connected with NO1, and COM2 is controlled to be connected with NO 2; at this time, the microphone of the wired earphone is switched to the output voice (AU _ OUT) path of the intercom component on the back clip for receiving the intercom voice. Meanwhile, GPIO14 is set to be high level, COM1 in the analog switch U5 is controlled to be connected with NO1, and COM2 is controlled to be connected with NO 2; the GPIO15 is set to be high level, COM1 in the analog switch U4 is controlled to be connected with NO1, and COM2 is controlled to be connected with NO 2; at this time, the microphone of the wired earphone is switched to the audio input (AU _ IN) path of the intercom component on the back clip for sending the intercom voice. Referring to fig. 14, fig. 14 exemplarily provides a schematic diagram of a control circuit when a back clip implements a talk-back function through a wired headset in an embodiment of the present application.

And step S1206, if the terminal monitors the Bluetooth headset access notification, the terminal is controlled to be disconnected with the talkback component of the back clip.

When monitoring that the Bluetooth component on the back clip has standard Bluetooth headset access, the Bluetooth component automatically pairs with the Bluetooth headset, namely, the Bluetooth headset model preset through a Bluetooth chip, and after the Bluetooth component successfully pairs, the Bluetooth component informs the controller of the back clip through a BT _ LINK signal, the controller transmits the information of the Bluetooth headset connection back clip to the terminal through a TXD0 interface, and the terminal monitors the Bluetooth headset access notification at the moment. And after monitoring the Bluetooth headset access notification sent by the back clip, closing the analog switch U2 and the analog switch U5, namely connecting COM1 and COM2 IN the analog switches U2 and U5 with NO1 and NO2, and connecting NC1 and NC2 to cut off audio channels of the talkback component and the terminal, wherein the output audio (AU _ OUT) of the talkback component is connected to LINE _ IN (input audio) of the Bluetooth component, the input audio (AU _ IN) of the talkback component is connected to LINE _ OUT (output audio) of the Bluetooth component, and the talkback voice is transmitted through the Bluetooth headset. Referring to fig. 15, fig. 15 exemplarily provides a schematic diagram of a control circuit when a back clip implements a talk-back function through a bluetooth headset in an embodiment of the present application.

It should be noted that, after the terminal receives the bluetooth headset access notification sent by the folder, the terminal is notified that the bluetooth module is not connected to the bluetooth headset, so as to avoid voice collision. When it is determined that the talk-back function is not used, the bluetooth module of the terminal may be connected to the bluetooth headset.

In a possible implementation manner, after the bluetooth component of the back clip is connected to the bluetooth headset, the connection state of the bluetooth headset is also monitored in real time, and after the disconnection of the bluetooth headset is determined, the bluetooth component sends a notification to the controller of the back clip, and the controller sends a notification that the bluetooth headset is not connected or the bluetooth headset is disconnected to the terminal. When the terminal receives the notice that the Bluetooth headset is not connected or the Bluetooth headset is disconnected, which is sent by the back clip, the analog switch U2 and the analog switch U5 are turned on, and the default state is restored.

In the embodiment of the application, the talkback PTT key is placed on the terminal, when the talkback function is used, the PTT key is pressed down when talkback voice is to be sent, the terminal monitors that the information of the key is pressed down by a serial port after the PTT key is pressed down, the GPIO4 is set to be low level after the information is received by the controller of the back clip, the terminal is used for starting the talkback voice sending, and if the terminal is in the talkback mode of the Bluetooth headset, the controller of the back clip synchronously sets the PTT (BT) to be low level to inform the Bluetooth component of starting the talkback voice sending path.

Set up the high level with the SQ signal when the effectual speech signal is received to the module of talkbacking, the back splint passes through the controller and gives the terminal with this information transfer, and the terminal is opened speaker or earphone and is enabled for receive the pronunciation of talkbacking. If the Bluetooth headset is in the talkback mode, the controller on the back clip sets SQ (BT) to high level for informing the Bluetooth component to start a voice receiving path.

In the application, at least one expansion function of a talkback function, a radio frequency identification function and a gas detection function is realized in the back clip; the back clip performs data interaction with the terminal, and transmits data information associated with at least one entity component to the terminal when monitoring a control instruction sent by the terminal aiming at the at least one entity component and/or determining that the back clip meets a data transmission condition associated with the at least one entity component, so that the terminal controls the working state of at least one functional device associated with the terminal based on the data information; when detecting the during operation, only need carry back splint and terminal, conveniently carry, and can carry out data interaction when satisfying data transmission between terminal and the back splint, realize the operation unified to the extended function in the back splint, the lifting means ease of use guarantees terminal operating condition's accuracy, provides work efficiency.

Fifthly, upgrading the Bluetooth part and controlling the process:

referring to fig. 16, fig. 16 exemplarily provides a control flow chart for upgrading a bluetooth component in a back clip in an embodiment of the present application, including the following steps:

and step S1600, after the terminal monitors that the upgrading APK application of the Bluetooth component installed on the terminal is started, upgrading a control instruction to the back clip Bluetooth.

Illustratively, the terminal sends a bluetooth upgrade control command to the cradle through a TXD interface in the UART communication interface.

Step S1601, after receiving the Bluetooth upgrading control instruction sent by the terminal, the back splint switches the working mode of the Bluetooth component from the master mode to the slave mode.

For example, the controller of the folder receives a folder bluetooth upgrade control instruction sent by the terminal through an RXD0 interface in the UART communication interface, recognizes the folder bluetooth upgrade control instruction, and sets the BT _ DL signal to a high level after determining that the folder bluetooth upgrade control instruction is an instruction for controlling the bluetooth component to upgrade, so that the bluetooth component changes the operating mode from the master mode to the slave mode when monitoring the high level.

And step S1602, the terminal is connected with the back clip in a Bluetooth mode.

At this moment, the working mode of the Bluetooth module in the terminal is a master mode, the terminal can be connected to the Bluetooth component of the back splint through Bluetooth, and at this moment, the software of the Bluetooth component of the back splint can be upgraded through Bluetooth connection.

Step S1603, the terminal transmits a Bluetooth upgrading data instruction to the back folder in a Bluetooth mode.

At this moment, the terminal directly transmits the Bluetooth upgrading data instruction to the Bluetooth component of the back splint in a Bluetooth mode.

And step S1604, the back clip upgrades the Bluetooth component based on the Bluetooth upgrade data instruction.

It should be noted that, after the back clip switches the working mode of the bluetooth component from the master mode to the slave mode, the back clip may feed back a notification that the working mode has been switched to the terminal, so as to notify the terminal that the back clip can be connected in a bluetooth manner; the terminal can also not be fed back with the notification that the working mode is switched, and the terminal determines whether the Bluetooth of the back clip can be connected or not in a self-scanning mode and directly connects after the connection is determined.

Still realized bluetooth function in the back splint to support bluetooth headset pronunciation of talkbacking, still need upgrade the bluetooth part in the back splint in order to guarantee the accuracy of bluetooth part work in the back splint simultaneously. After monitoring a Bluetooth upgrading control instruction sent by the terminal, the controller switches the working mode of the Bluetooth component from a master mode to a slave mode, and when monitoring a Bluetooth upgrading data instruction transmitted by the terminal in a Bluetooth mode when the Bluetooth component is in the slave mode, the controller upgrades the Bluetooth component based on the Bluetooth upgrading data instruction to realize the upgrading operation of the Bluetooth component and ensure the working accuracy of the Bluetooth component in the back splint.
