基于LabVIEW与PLC的水源地无线远程监控系统设计

摘要

提出了一种基于LabVIEW的无线远程监控系统的设计,来满足水源地需要人工现场控制及分散管理的需求.采用Modbus协议,通过RS485总线实现现场设备通信,然后经过串口服务器,通过无线局域网实现现场设备与上位PC机的通信.实践证明:系统实现简单、通信可靠,并且具有很好的扩展性,基本满足了水源地远程监控的需求,提高了水源地的管理条件.%Considering the requirement for manual control and decentralized management on water head sites, a LabVIEW-based wireless remote monitoring system was proposed to implement communication with field devices via RS485 bus and based on Modbus protocol, and then to realize field device communication with host PC via both serial server and a wireless local area network. Application in practice proves this simple and reliable and expansible system as the water head site management required.
