A few days ago, in response to the problems of serious aging and reduced sensitivity of water meters in urban communities, and disturbing citizens by reading meters at home, Diaobingshan City plans to invest a total of 30 million yuan, using Shanghai Sangrui Electronic Technology Co., Ltd. with low energy consumption and good stability. Wamr Net System wireless meter reading solution and Liaoning Minsheng Intelligent Instrument Co., Ltd. LXSZ wireless remote transmission intelligent valve-controlled wet water meter about 70,000, implemented wireless intelligent water meter transformation for 30,000 local residents. Among them, in the first phase of the project, 150,00 wireless smart water meters were used to replace 7,000 residents of urban nurseries, 2000 square meters, Hongda, Fengyuan and other residential areas free of charge for intelligent water meter replacement. This is the first successful practice of the Internet of Things and wireless sensor network in China’s energy measurement. It is reported that the current project has started and is nearing completion. The system’s first-time copying rate is >99.5%, and the second-time copying is 100%.
The system uses the SRWF-8009 wireless remote meter reading module with automatic frequency hopping, three-level routing and automatic wake-up functions from Shanghai Sangrui Electronic Technology Co., Ltd., which solves the problems of co-frequency interference and meter reading distance; The storage function can store the data of the water meter, which can meet the requirements of reading data from the portable handheld device or reading it remotely through GPRS. According to different meter reading requirements, the system can use hand-held meter reading device on-site one-button copying, and can also realize GPRS/CDMA remote data transmission upwards, so as to ensure high coverage rate with low cost. Wamr Net System adopts Wamr Net ad hoc network wireless communication technology, combined with mature GPRS/CDMA uplink channel and cooperates with the marketing management MIS system of each public utility company to establish an interface with the information system of water supply company, so as to realize remote meter reading .
The automatic meter reading system and smart meter can enable the water supply company to realize fast meter reading, reduce the cost of copying, and improve the fund collection rate of the water company. When Diaobingshan City chose the Wamr Net System solution with the function of network real-time management, it not only improved the accuracy of system measurement, but also improved the corresponding service level.
The successful implementation of the metering project to benefit the people marks that my country’s urban basic public utilities have begun to adopt technological innovations to improve the management efficiency of public utilities. With the popularization and application of wireless communication technology and sensor network technology in public utilities, the information management of public utilities will also be rapidly improved. Favored for renovation and installation of new buildings.
