[China Instrument Network Instrument Industry] On June 13th, the State Grid Jiangsu Electric Power Company successfully implemented a large user remote meter data collection copy work. This means that the water meter data of large users in Jiangsu Province can be collected by the power supply companies in the future.
Large diameter water meter
At present, multi-table collection in Jiangsu Province is limited to residential users' water and gas meters and has not yet achieved the collection and collection of large-scale water and gas meter data. This year, the State Grid Jiangsu Electric Power Co., Ltd. expanded the scale and depth of multi-table acquisition, and expanded multi-table acquisition and construction from residential customers to large users. In the Jintan District of Changzhou, Jiangsu, pilot water meter information collection for large users is the first step to promote multi-table acquisition by large users.
“First of all, most of the water meters are installed outdoors and cannot provide AC power for the acquisition terminal. It is necessary for the terminal to have its own battery for power supply. Second, some large users' water meters are buried in the water meter wells, and the water meters and acquisition terminals may remain in the water for a long time. In the sewage, the data acquisition equipment needs strong communication signals, strong anti-jamming capability, and good waterproof performance.Finally, large users choose various types of water meters, and the collection terminal can simultaneously collect data from most of the water meters in the market in order to meet the requirements for data collection. All of them have created obstacles for the promotion of large-scale multi-table collection and construction, said the person in charge of the State Grid Jiangsu Electric Power Marketing Department.
To solve this problem, the State Grid Jiangsu Power actively visited the equipment manufacturers, through the cooperation with the manufacturers to develop new types of acquisition terminal, the data of the on-site water meter was collected and stored, and the large-caliber water meter data was realized through the power consumption information collection system. Remote collection work. The data collection terminal meets the requirements of dustproof, waterproof, anti-signal interference and other requirements for large-diameter water meter remote copying. The battery-powered terminal uses no external power supply.
“In the past, for important users such as large users, due to the large amount of water, we all arranged special personnel to copy one site each day. Now we cooperate with the power supply companies and we can only know the water situation in the office every day, which greatly reduces the number of manual meter readings. , It is very convenient. At the same time, the power supply company can also push daily water usage regularly, so that I can now access the water situation. Power supply company's multi-table collection facilitates our company's information acquisition.†Jintan District Water Company related person in charge Cao Bin said. It is reported that the pilot large water meter information collection is installed on the water meter's general table and sub-tables. For large users, it is possible to fully understand the situation of water use, to detect leaks and improve energy efficiency. Reduce the operating costs of large user companies, at the same time, reduce the cost of manual meter reading for water supply companies and reduce the workload.
