摘　　要：供水管网作为城市发展生命线,对其进行水质监测是保障供水安全的重要措施。其中,利用水质在线仪表监测供水水质已成为智慧水务中的重要一环。目前受安装条件的限制,管网水质在线仪表大多都固定安装于二次供水泵房,无法监测到主管网水质,监测不全面,代表性不强;同时在供水管道迁改和抢修施工过程中难以实时全面掌握受影响区域的水质波动情况。文章设计了一套集水样采集、UPS供电、水质仪表为一体的Modbus TCP的临时水质在线监测系统,该系统各环节设计自成一体,可分开可联用,安装简单,移动方便,可临时安装于供水主管道、消防栓、二次供水泵房等,有针对性实时监测多种场景下管网的水质变化情况,有效保障管网水质安全。As the lifeline of urban development,water quality monitoring of the water supply network is an important measure to ensure water supply safety.Among them,using online water quality instruments to monitor water supply quality has become an important part of smart water management.Currently,due to installation limitations,most online water quality instruments in the pipeline network are fixed and installed in the secondary water supply pumping station,making it impossible to monitor the water quality of the main pipeline network.The monitoring is not comprehensive,and the representativeness is not strong.At the same time,it is difficult to comprehensively grasp the water quality fluctuations in the affected areas in real time during the relocation and repair of water supply pipelines.This paper designed a temporary water quality online monitoring system based on Modbus TCP,which integrated water sample collection,UPS power supply,and water quality instruments.The system was designed as a separate and interconnected system,with simple installation and convenient movement.It can be temporarily installed in the main water supply pipeline,fire hydrants,secondary water supply pumping stations,etc.It can monitor the water quality changes in various scenarios in a targeted and real-time manner,effectively ensuring the water quality safety of the pipeline network.
