The program updating interface and the 485 communication interface of the conventional AGV main control board are arranged on the main control board of the AGV, and the AGV panel is arranged on the outer side of the main control board.

When updating the firmware program, an operator needs to open the AGV panel and toggle the dial switch, and then the program updating interface of the AGV main control board and the computer are connected through the data line, so that the program of the main control board can be updated through the computer. As shown in fig. 2, the specific scheme is as follows: the main control board is provided with an MCU module based on an STM32F103 chip, and when a program is updated, a BOOT0 signal pin of the MCU chip needs to be set high first, and then the MCU chip is electrified, so that the 'download' mode updating program can be entered; after the update is completed, the BOOT0 needs to be pulled down and powered on again, and the MCU chip can be started normally, otherwise, the MCU chip will continue to enter the "download" mode to wait for the update program but cannot be started normally. Therefore, the operating mode of the main control board can be switched to a program downloading mode or a normal operating mode by setting the dial switch and operating the dial switch to set the BOOT0 signal pin high or low.

When the AGV manual operator needs to be connected, the AGV panel also needs to be opened, the 485 communication interface is connected with the interface of the manual operator through a data line, and the AGV can be controlled through the manual operator.
