利用RS-485总线实现安防与环境监测系统的数据通信

Data communication by RS-485 Bus in the system

在不用重新铺设通信线缆的情况下,利用现有的通讯线路,采用RS-485总线技术加中继的办法,使用一台中心控制计算机,经济、有效地解决远程分散库房群安防与环境监测系统中数据通信的问题。

To make use of RS-485 Bus and relay technology to implement communication between the control center and each detected spot, and uses one computer to implement all task of collect and deal with the data sent by modules in each storeroom. In this way, it is no longer need to lay the network cable among each storeroom and control center.
