摘　　要：针对城区供水管网漏损率较高,供水管网数据统计滞后的问题,设计一种基于LoRa和NB-IoT物联网技术的智能管网监测系统。该系统通过端点采集设备对管网设施运行状态(包括压力、流量、水质等信息)进行实时监测,通过管网监测终端将数据传输到管网运营平台,提高供水管网漏损的信息化管理水平。实验结果表明:通过管网监测系统的合理布局和数据信息的及时上传,可以实时查看管网设备的运行状态,抄读成功率达99%以上,为供水管网漏损控制提供重要依据。Aiming at the problem of high leakage rate of urban water supply network and lagging data statistics of water supply network, an intelligent pipe network monitoring system based on LoRa and NB-IOT Internet of things technology was designed.The system monitored the operation status of pipe network facilities including pressure, flow, water quality and other information in real time through the endpoint acquisition equipment, and transmitted the data to the pipe network operation platform through the pipe network monitoring terminal, so as to improve the information management level of water supply pipe network leakage.The experimental results show that through the reasonable layout of the pipe network monitoring system and the timely upload of data information, the operation status of pipe network equipment can be viewed in real time, and the reading success rate is more than 99%,which provides an important basis for the leakage control of water supply pipe network.
