[0028] Multiple serial communication interfaces are reserved, facilitating the expansion of the function board. When new communication functions need to be added or new serial devices need to be connected, there is no need for large-scale modifications to the function board, reducing the cost and difficulty of system upgrades.
[0029] The design adopts a modular approach, separating power supply, communication, control, and interface functions into independent units. This design facilitates production, debugging, and maintenance, improving product reliability and maintainability.
[0030] The use of signal isolation and level conversion circuits in the communication unit effectively enhances the stability and anti-interference capability of communication, ensuring accurate and reliable transmission of commands even in complex electromagnetic environments.
