大坝分布式数据采集系统中通讯网络的设计

Design of Communication Network of Distribute Data Collection System of Dam

介绍由一台ＰＣ４８６／５８６作主机、一台ＭＣＳ５１系统作主站、３２台ＭＣＳ５１系统作子站的分布式数据采集通讯系统网络的设计。具有有线、无线两种通讯方式以及自动转换功能。本系统还设计了专门长线发送器、接收器电路，解决了不需中继器有线传输达１０ｋｍ以上的问题。

This article introduces the design of communication network of distribute data collection system of dam which is composed of main computer with PC486/586、wireless communication and auto-switch function in two modes.We alse design special transmitter and receiver circuit with which can transmit 10km in wire without relay.
