[0002] When producing smart transmitters, the accuracy of parameters needs to be calibrated. Before leaving the factory, it is necessary to check whether the communication of the product is normal. When using it, the operating parameters of the transmitter need to be adjusted. However, the premise for performing the above operations is that the smart transmitter establishes a communication connection with the computer, that is, the terminals of the transmitter are connected to the computer serial port with a cable, and then the above operations are performed on the transmitter through the computer. However, these operations are cumbersome, and if the cables are connected incorrectly, the computer and the transmitter cannot communicate, and the correct wiring sequence needs to be adjusted, which makes the configuration of smart transmitter parameters inefficient.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The present application embodiment discloses a Bluetooth communication module for configuring smart transmitter parameters. Figure 1 The Bluetooth communication module for configuring the parameters of the smart transmitter includes a master Bluetooth module 2 and a slave Bluetooth module 3, wherein the master Bluetooth module 2 is set on the computer 1, and the slave Bluetooth module 3 is set on the transmitter 4. The master Bluetooth module 2 is connected to the slave Bluetooth module 3 by searching, and the computer 1 exchanges information with the transmitter 4 through the communication channel established between the master Bluetooth module 2 and the slave Bluetooth module 3, and configures the parameters of the transmitter 4.

[0033] The master Bluetooth module 2 is integrated on the computer 1 and controlled by the APP program in the computer 1. In this example, the master Bluetooth module 2 is a PCBA board with integrated Bluetooth function originally on the computer 1, which is mainly used to automatically search for the slave Bluetooth module 3 and realize short-range wireless communication with the slave Bluetooth module 3. The slave Bluetooth module 3 is connected to the transmitter 4 through a detachable connection. When the transmitter 4 has a configuration parameter requirement, the slave Bluetooth module 3 is installed on the transmitter 4. The computer 1 configures the parameters of the transmitter 4 through the communication channel established between the master Bluetooth module 2 and the slave Bluetooth module 3. After the configuration is completed, the slave Bluetooth module 3 is unplugged and can be reused, which improves the configuration efficiency and reduces the configuration cost.

[0034] Reference Figure 2, the slave Bluetooth module 3 includes a transceiver unit 31 and a transparent transmission unit 32 integrated on a PCB, and a first speed plug terminal and a second speed plug terminal are provided on the PCB, which are represented by A and B respectively. The transmitter 4 is provided with a first wiring terminal corresponding to the first speed plug terminal, and the transmitter 4 is also provided with a second wiring terminal corresponding to the second speed plug terminal. USB can be used as the interface hardware between the slave Bluetooth module 3 and the transmitter 4, and the first speed plug terminal and the first wiring terminal are connected in series by the USB interface, and the second speed plug terminal and the second wiring terminal are connected in series. The first wiring terminal and the second wiring terminal can also be set between the slave Bluetooth module 3 and the transmitter 4 to be located in different embedded grooves, and the first speed plug terminal is inserted into the embedded groove where the first wiring terminal is located so that the two are abutted against each other, and the second speed plug terminal is inserted into the embedded groove where the second wiring terminal is located so that the two are abutted against each other, so as to achieve the purpose of installing the slave Bluetooth module 3 on the transmitter 4, and when disassembling, directly unplugging the first speed plug terminal and the second speed plug terminal can achieve separation from the Bluetooth module 3 and the transmitter 4, and the disassembly is simple and efficient.

[0035] Among them, the transceiver unit 31 includes a max3485 chip and a circuit breaker. The max3485 chip has 8 pins, and pin 1 is an output pin, which is connected to the transparent transmission unit 32. Pins 2 and 3 are enable terminals, which have the function of controlling the max3485 chip to send data to the transmitter 4 or receive data from the transmitter 4. Specifically, when pins 2 and 3 are both low levels, data enters from pin 1 and is transmitted to the transmitter 4. When pin 2 is low and pin 3 is high, the max3485 chip receives data from the transmitter 4 and outputs it. Pin 4 is also connected to the transparent transmission unit 32. Pin 4 is used to output the data on the transmitter 4 to the transparent transmission unit 32 when pin 2 is low and pin 3 is high. Pin 5 is a ground pin, pin 6 is the in-phase output terminal of the max3485 chip, pin 6 is connected to the first speed plug terminal through the circuit on the PCB board, pin 7 is the inverting output terminal of the max3485 chip, pin 7 is connected to the second speed plug terminal through the circuit on the PCB board. In order to ensure the safety of the max3485 chip when connected to the transmitter 4 and prevent the instantaneous current on the transmitter 4 from damaging the max3485 chip, a circuit breaker is set on the line connecting pin 6 to the first speed plug terminal, and a circuit breaker is also set on the line connecting pin 7 to the second speed plug terminal. For easy distinction, FW1 represents the circuit breaker on the line connecting pin 6 to the first speed plug terminal, and FW2 represents the circuit breaker on the line connecting pin 7 to the second speed plug terminal. Pin 8 is the power supply terminal of the max3485 chip. A charging port corresponding to pin 8 is set on the PCB board. The charging port is connected to an external power supply device or a battery on the PCB board. The charging port can convert the received voltage into the working voltage of the max3485 chip, such as converting it into a 3.3V voltage and then transmitting it to pin 8, so that the max3485 chip obtains the required working voltage and ensures the safe and stable operation of the max3485 chip.

[0036] In addition, in order to further ensure the security of the max3485 chip, the transceiver unit 31 also includes a bidirectional voltage regulator diode. Figure 2 In the figure, it is represented by T1. One end of the bidirectional voltage regulator diode is located on the line connected to pin 6 and the first fast plug terminal, and the other end is located on the line connected to pin 7 and the second fast plug terminal. At the same time, a capacitor is also arranged in parallel on pin 8, and the capacitor is represented by C1. The end of the capacitor away from the charging port is grounded to ensure the safe power-on of the max3485 chip.

[0037] The transparent transmission unit 32 includes a HM-BT4531 chip and a driver. The HM-BT4531 chip has 12 pins. Pin 1 is an interrupt pin. Pin 1 is connected to a single-chip microcomputer. The single-chip microcomputer is used to control pin 1 to switch between a high level and a low level. In order to visually check whether pin 1 is a high level or a low level, an indicator light, such as an LED light, is connected in series on the line connecting the single-chip microcomputer and pin 1. In order to ensure that the indicator light correctly indicates whether the light is on or off, a first resistor is connected in series on the power supply line between the indicator light and the power supply for the indicator light. The first resistor is represented by R1 to improve the impedance matching between the indicator light and the power supply. Pins 2, 3, and 4 are all ground pins.

[0038] Pin 5 and pin 6 are connected to the driver, which consists of two parallel electric switches. In this example, the driver is also connected to the charging port through the circuit on the PCB board, so that the voltage on the driver is also 3.3V. Specifically, the two electric switches are the first switch and the second switch, respectively represented by S1 and S2. Pin 5 is connected to the second switch, and the end of the second switch away from pin 5 is grounded. The common end of pin 5 connected to the second switch is also connected to a second resistor, and the second resistor is represented by R2; pin 6 is connected to the first electric switch, and the end of the first electric switch away from pin 6 is also grounded, and the common end of pin 6 connected to the first switch is also connected to a third resistor, and the third resistor is represented by R3.

[0039] Pin 7 is the power supply terminal of the HM-BT4531 chip, which is connected to the battery on the PCB board. The battery supplies power to the HM-BT4531 chip, and the battery is represented by BAT.

[0040] Pin 8 of the HM-BT4531 chip is connected to pin 1 of the max3485 chip, and pin 9 of the HM-BT4531 chip is connected to pin 4 of the max3485 chip. Pin 8 and pin 9 of the HM-BT4531 chip are both universal asynchronous receivers and transmitters, which are used to realize bidirectional data transmission between the HM-BT4531 chip and the max3485 chip.

[0041] Pin 10 of the HM-BT4531 chip is the ground terminal, and pin 11 is an extension pin, which can be used to connect to an external programming computer 1 to achieve customized design of each pin, and pin 12 is the input pin of the clock signal. Pin 12 of the HM-BT4531 chip is respectively connected to pin 2 and pin 3 of the max3485 chip. The line connecting pin 12 of the HM-BT4531 chip to pin 2 and pin 3 of the max3485 chip is also connected to a single-chip microcomputer. The single-chip microcomputer controls pin 2 and pin 3 of the max3485 chip to switch between high level and low level, thereby driving the max3485 chip to switch between receiving mode and sending mode.

[0042] In actual application, after the HM-BT4531 chip is powered on through pin 7, the first switch and the second switch are closed to drive the HM-BT4531 chip into the working mode, and at the same time drive the max3485 chip into the receiving mode. The master Bluetooth module 2 searches for the slave Bluetooth module 3, and establishes a communication connection after finding the slave Bluetooth module 3. After the connection is successful, data transmission is performed or the specified AT command is output to configure the serial port baud rate of the transmitter 4, the connection interval of the master Bluetooth module 2 and the slave Bluetooth module 3 and other parameters. The AT command is a string starting with "TTM:" and ending with "\r\n\0".

[0043] In a specific example, the AT command includes TTM:CIT-Xms, TTM:NAM-?, TTM:BPS-?, TTM:REN-x, TTM:BPS-x, where TTM:CIT-Xms indicates changing the connection interval between the master Bluetooth module 2 and the slave Bluetooth module 3, and X in TTM:CIT-Xms indicates a specific time interval in ms. TTM:NAM-? indicates querying the name of the slave Bluetooth module 3. TTM:BPS-? indicates querying the serial port baud rate of the transmitter 4. TTM:REN-x indicates changing the name of the slave Bluetooth module 3, and x indicates the name of the set Bluetooth module. TTM:BPS-k means setting the serial port baud rate of transmitter 4, k means the baud rate to be set, and the baud rates that can be set are 9600, 19200, 38400, 57600, 115200, 250000, 500000. For example, TTM:BPS-115200 means setting the serial port baud rate of transmitter 4 to 115200.

[0044] It should be noted that after the master Bluetooth module 2 and the slave Bluetooth module 3 establish a communication connection, if the second switch is disconnected, the master Bluetooth module 2 and the slave Bluetooth module 3 automatically disconnect the communication connection, and if the first switch and the second switch are disconnected at the same time, the slave Bluetooth module 3 maintains the working mode and automatically forwards the data output by the computer 1 to the transmitter 4. At this time, the indicator light also remains on. When the data forwarding work is completed, the indicator light goes out.

[0045] It can be seen from this that the Bluetooth communication module for configuring the parameters of the smart transmitter of the present application can not only enable the computer 1 and the transmitter 4 to communicate using wireless communication, reducing the limitations of physical lines, such as reducing the need to ensure the correct interface installation sequence, prevent interface aging, and ensure the appropriate cable length. The complicated process, the computer 1 and the transmitter 4 can quickly establish a communication connection through the main Bluetooth module 2 and the slave Bluetooth module 3, and after the communication connection is established, the specified instructions can be sent to quickly complete the parameter configuration of the transmitter 4, thereby improving the efficiency of configuring the transmitter 4.
