摘　　要：本文介绍了 ModBus 协议的原理和在信号无线监控系统上的应用,提出了可有效延长通信距离的中继地址编码方案和传输实观方法,提出了用 VC 编程通过串行口直接控制数传模块的方案。并讨论了无线数据传输抗干扰措施的一些关键技术问题和解决方法。The elements of ModBus Protocol is introduced briefly and its application in wireless monitoring system is discussed. A relay-addressing method is given to extend the communication distance and scheme of a direct control of RF unit with serial port of PC base on VC programming is also given. Some important issues such as data transmission handling and methods of anti-interference are discussed in detail.
