通过分析目前传统供水监控系统的组网方式,提出了一种新的供水组网方式——基于串口服务器组网.并以LG-IG5系列变频器为例,介绍了它的组网过程、通讯协议和通讯软件的设计.该系统通过串口服务器将变频器与互联网相连,方便灵活地实现对供水系统的远程监控.系统结构简单,成本低,很好地适应了供水系统远程控制与网络化控制的需要. By analyzing the networking mode of the traditional water supply monitoring system, a new water supply networking mode is proposed based on the serial port server networking.With LG-IG5 series inverter as an example, its networking process, communication Protocol and communication software.The system connects the inverter to the Internet through a serial port server, which can realize the remote monitoring of the water supply system conveniently and flexibly.The system is simple in structure and low in cost and well adapted to the water supply system remote control and networked control Need.
