This design configures the corresponding parameters through the host computer. After receiving the configuration parameters, the microcontroller unit selects the corresponding input and output hardware channels, and then initializes the corresponding peripherals according to the hardware channel selection configuration parameters, calls the matching data parsing program, and waits for data to be received and sent.

[0014] The DCDC power switching module is connected in parallel with the high-speed one-to-multi-way analog switch switching module, RS232 module, RS485 module, RS422 module, CAN module, high-speed one-to-two-way analog switch switching module, microcontroller unit, TRDP module, MVB module, and DC power input terminal through wiring. A wide voltage is input to the DC power input terminal to provide working power for the entire system. The input voltage range is: DC40V~DC160V. The microcontroller unit is connected to the program download port through wiring, and the program download port is used to connect to the host computer. The host computer configures corresponding parameters and inputs them into the microcontroller unit.

[0015] The microcontroller unit includes a central processing unit (CPU) and an EEPROM memory, wherein the CPU is connected to the EEPROM memory via wiring, and the EEPROM memory is connected to a DCDC power switching module via wiring for power supply, wherein the EEPROM memory is used to store data and save parameters configured by the host computer.

[0016] An RS232 module is connected in series between the microcontroller unit and the program download port, and the RS232 module is connected to the DCDC power switching module through wiring. After the host computer configures the parameters, the program is downloaded through the RS232 module. After receiving the configuration parameters, the microcontroller unit selects the corresponding input and output hardware channels and selects the corresponding data parsing program to complete data reception and transmission.

[0017] according to Figure 2 As shown, the program operation process is divided into two parts: 1. Power-on initialization; 2.

[0018] Normal system operation stage: After the initialization is completed, the system runs normally. The system runs in the original parameter configuration mode. After receiving the configuration command transmitted by the parameter configuration tool, it responds to the parameter (channel configuration, baud rate and other parameter configuration) configuration program and then saves the configuration parameters; For example: in the original input channel selection RS232 module, output channel selection TRDP mode, you need to switch to input channel CAN module, output channel TRDP mode, then the input hardware circuit channel is switched from RS232 hardware channel to CAN hardware channel, the input data parsing program calls the CAN data parsing program, and the output data parsing program continues to call the TRDP data parsing program; Parse the data received by the input and output channels and forward them.
