摘要
介绍基于RS485总线构建半双工主从式上下位机多机通信网络,完成仓房粮温监控系统设计.以PC机为主机,单片机为从机,使用Delphi的CPort控件实现PC机与单片机的多机通信,给出了RS485通信网络接口的硬件设计和软件设计,分析了通信的可靠性问题,并给出相关的解决方法.
A Half-Duplex Master-Slave multi-communication network system based on RS485 bus is presented. A barn grain temperature monitoring system is designed. The master is PC while the slave is Micro Controller. The communication between them is realized by using the CPort control in Delphi. The hardware design and software design of RS485 communication network interface is given. Analysis about the reliability of communication is presented and some methods and suggests are given.
