摘要
本文介绍了一种ＰＣ机与单片机组成分布式多机实时通信系统的方法。讨论了通信的实现原理及监控软件的设计思想。通过引入ＲＳ２３２总线管理方法，克服了以往分布式系统中主机长时间处于“等待”状态的弱点，提高了系统的可扩展性和可维修性。
In this paper , we introduce a real-time communication method between PC and single-chip microcomputers in a distributed control system . The principle of implementation and the method of software design is detailed. There is not “waiting”state in the PC running , The extensibility and maintainability of the system have been improved.
