摘要
基于单片机的串行通信原理,设计了一种RS485通信接口的主从分布式串行多机通信系统.搭建了在PC机控制下的多个步进电机运转的硬件电路,设计了VC++的人机交互界面和主从机通信软件.系统具有性能稳定、运行可靠、扩展性强的特点,可用于远距离通信,适用于工业控制系统.
According to serial communication theory, a master-slave distributive serial multi- computer communication system based on RS485 communication interface is proposed. The hardware circuit is constructed based on multi stepping motors under the control of PC. Human- computer interaction interface based on VC ＋ ＋ and software of communication between master and slave computer are designed. The system has the character of steadiness, reliability and extensibility. It can be used for industrial control system of remote communication.
