摘要
介绍了一种基于RS-485总线的分布式测控系统,给出了系统结构、通讯协议和测控模块的通讯程序。上位机用VisualBasic6 0的MSComm控件编程实现了数据采集与控制。运行结果表明:系统工作可靠,具有很好的效果。
A means of distributed measurement and control system was introduced.The system structure,communication protocol and program of the measurement & control modules were given.The data acquisition and control of the supervisor was implemented with MSComm ActiveX of the Visual Basic6.0 program language.Application results show that it is a cheap and reliable system.
