1. Plan Overview:
Customer Challenge:
1) Most water companies lack a pumping station management platform, and the system does not fit the pumping station management scenario when using the system.
2) Pumping stations are mostly located far away and the cost of manual duty is high.
3) Equipment faults are not discovered and dealt with in a timely manner, which affects the stability of water supply and causes complaints.
4) Pumping station pressure adjustment is mostly based on experience, which may cause waste of energy consumption and increase operating costs.
As the main facility of municipal construction and management projects, pumping stations are responsible for the important task of urban drainage and flood prevention. The pumping station establishes an independent on-site automated control system with complete functions, and establishes a centralized monitoring and control room to realize automated operation control of the pumping station. The operation of various equipment in the pump station is directly controlled by the local control system of the pump station. The local control system of the pump station is controlled based on the operating conditions of the pump station such as liquid level. The pumping station receives the global operating data and control instructions downloaded from the central monitoring system of the sewage treatment project as condition parameters for automatic control of the pumping station to cooperate with the flow-based control specified by the central monitoring system of the sewage treatment project.
The pumping station is the power system in the water transmission and distribution process of the water supply pipeline network. More refined management of the pumping station is one of the main means for water companies to reduce leakage and self-consumption of the water supply system. With the vigorous development of smart water construction and the popularization of Wupin.com technology in recent years, the use of more intelligent information systems to assist water companies in more efficient management of pumping stations has become an important step in improving the lean efficiency and pumping station management of water companies. level inevitable trend.
The pumping station monitoring and management system mainly consists of a dispatch center, a pumping station monitoring center, a communication platform, a pumping station remote measurement and control terminal, and metering and camera equipment. It is suitable for remote monitoring and management of water intake pump stations, booster pump stations, water plants, etc. in the water supply system. Pumping station managers can remotely monitor the water level of the clean water pool or incoming station pressure, working status of the pump unit, outgoing flow rate, outgoing pressure, etc. in the pumping station monitoring center; it supports manual control, automatic control, and remote control of the pump starting equipment. Start and stop; during optical fiber communication, the panoramic view and important workstations in the station can be monitored with images, making the pumping station unattended. Realize data sharing, comprehensive information analysis and processing, and intelligent operation management, improve the safety and reliability of pump station operations, operational efficiency, energy saving and consumption reduction, and ensure the safety, optimization, economy, and efficiency of pump stations.
