AI Technical Summary
The lack of license plates on mine dump trucks makes management and safety issues difficult to resolve.
Design a control circuit for an external license plate display screen for mining dump trucks, including a main control circuit and an LED driver circuit. Utilize an STM8 and GD32A microcontroller control circuit via serial communication to realize the display of license plate numbers and digital management of vehicle information. In the event of an STM8 communication failure, automatically switch to the redundant LED control pin to output control signals.
It enables the display and information management of license plates for mining dump trucks, meets the requirements for license plate settings, solves the problem of license plate management, and also reserves the function of load weight display, thereby improving the informatization level of vehicle management.
