基于RS485单片机多机串行通信的电子开关设计
Design of electronic switch for multiple MCUs serial communication based on RS 485
摘要
Abstract
In order to test the position of the large or medium-sized conveyor belt in transmission process, the electronic switch for multiple MCUs serial communication based on RS 485 was designed. The overall scheme and the hardware circuit are mainly introduced. The electronic switch based on RS485 communication has better anti-interference ability, realizes the long distance communication and avoids the data communication conflict when multiple slaves communicate with the master at the same time. Experiment indicates that the electronic switch has simply structure and powerful stability and can be used in industrial control, testing and other fields.关键词
