Case 1 - Baoding Drainage Pump Station Monitoring Project
Baoding City Drainage Corporation is responsible for the rainwater, sewage discharge and sewage treatment in the entire Baoding city, and has a total of 31 rain/sewage pumping stations and 3 sewage treatment plants.
For a long time, each pumping station and sewage treatment plant has developed its own system and operated independently, forming an island of information. In the past, due to the fact that management was completely dependent on labor and information was not delivered in a timely manner, it often caused various operational and maintenance failures. Drainage system is not only difficult to manage, has low implementation efficiency, but also has poor social influence and high manual management costs. In order to completely solve the above problems, Baoding Drainage Corporation invested and built a digital information management platform in 2012.
Communications network
According to the actual situation of the rain/sewage pumping station and the sewage treatment plant, the field equipment adopts two monitoring methods:
1. Monitoring points of pumping stations collect various signals of on-site pumps, valves, meters, and audio and video equipment through the monitoring equipment of the drainage pump station, and realize long-distance transmission of data and audio and video through the optical fiber network.
2. All kinds of equipment and instrument data in the sewage treatment plant have been collected in the plant's central control room. Data is then automatically acquired from the configuration software of the central control room through data communication software, and the data and live video are transmitted to the digital information through the optical fiber network. Management platform.
