摘要
为了解决长距离供水管道运行状况及企业用水量巡查困难、实现对长距离供水管道运行状况及企业用水量实时监测,设计了以微功耗遥测终端、流量计、压力传感器作为现地控制单元,以操作员站、服务器、工程师站等作为信息管理及中央控制层的无线4G管网监测系统。该监测系统通过4G网络技术连接现地控制单元和中央控制层,实现了对管网的压力、流量、企业用水量的实时监测。介绍了系统组成、系统功能、通信网络、电源。实际应用表明,该系统在实现管网监测过程中的可靠性、准确性。该系统充分发挥了微功耗终端、4G网络的优势,使供水管网监测更经济、可靠、简单易行,为解决长距离、监测点多且分散的管网监测提供了参考。
In order to solve the difficulties in running conditions of long-distance water supply pipelines and the inspection of water consumption for enterprises,the operation conditions of long-distance water supply pipelines and the real-time monitoring of water consumption for enterprises are realized.A wireless 4 G network monitoring system with micro-power telemetry terminal,flowmeter and pressure sensor as the current control unit,operator station,server and engineer station as the information management and central control layer are designed.The monitoring system connecting the local control unit and the central control layer is operated to realize the real-time monitoring of the pressure,flow,and enterprise water consumption of the pipe network by using the 4 G network technology.The system composition,system function,communication network and power supply system are respectively introduced.The practical application shows that the system is reliable and accurate enough in the process of pipe network monitoring.The system gives full play to the advantages of micro-power terminals and 4 G networks,making the monitoring of water supply network more economical,reliable,simple and easy,and providing a reference for solving long-distance,multi-point and decentralized network monitoring.
