【Industry Focus in the Instrumentation Network Industry in China】 Recently, with the successful development of the collection of electricity and water in the Xinhualian homeland in Xining City, Qinghai Province, the construction of the four-in-one collection demonstration project was strongly promoted by the State Grid Xining Power Supply Company. A major breakthrough was made and more than 1200 customers completed pilot projects across the province, 20% more than originally planned.


The “Four Tables One” acquisition is a major initiative of the State Grid Corporation of China to remotely collect water, electricity, gas, and heating, is an important measure for power grid companies to serve the construction of smart cities, and meet the needs of customers for smart energy use. It is a demonstration promotion of the State Grid Corporation of China. An important project,. Water, electricity, gas, and heat are the four-in-one collection site technology solutions, which are system solutions based on electricity information gathering communication networks and extending data collection functions of water, gas, and heat meters. The acquisition terminal uses the National Grid Concentrator Type I upgrade. The concentrator transmits the collected data to the collection master station system server through the GPRS public network. The meter reading system of the water, gas, and heat companies and the smart city system are connected through the external network. Acquisition master server to achieve data sharing, and provide customers with a package of energy usage query analysis, ladder warning and optimal energy planning.

In September this year, after the State Grid Qinghai Electric Power Company held a four-in-one pilot work arrangement meeting, the State Grid Xining Power Supply Company immediately investigated the status quo of the metering management of the public utilities in Xining, advanced deployment, self-pressurization, and developed a A collection of pilot construction goals, and combined with the actual situation in Xining, the pilot will be identified as the new Hualian home community. In the pilot construction process, the State Grid Corporation of China Xining Power Supply Co., Ltd. closely integrated with Xining City's opportunity to build a smart city and actively reported and communicated to the municipal government, striving for policy support in construction coordination, industry coordination, and project promotion. At present, the company has completed the four-in-one construction task for more than 1,200 households in three communities and has produced a good demonstration effect.
