Hefei pump station monitoring system will realize the monitoring of drainage facilities in the city in the future

Recently, Hefei is stepping up the construction of Tongling Road Pump Station Control Center project, which is expected to be fully completed and put into operation by the end of November.

The pump station monitoring system in Hefei can not only monitor the city's underpass bridge in the flood season, but also monitor the operation of the pump station, the main force of drainage, in real time, and overcome the disadvantages of relying on manual duty alone. It is understood that the pump station monitoring system in Hefei is mainly composed of dispatching center, pump station monitoring center, communication platform, remote measurement and control terminal of pump station and measurement (flowmeter) equipment. Through the remote measurement and control terminal RTU, the management personnel of the pump station can remotely monitor the liquid level or inlet pressure, working state of the pump unit, outlet flow, outlet pressure, etc. in the pump station monitoring center; Support the manual control, automatic control and remote control of the pump starting equipment to start and stop the pump set, so as to realize the unattended operation of the pump station. At the same time, the platform software of the monitoring center can remotely monitor the water level or inlet pressure, outlet flow and outlet pressure of the pump station, remotely monitor the working state, current, voltage, protection state and working mode of the pump unit, remotely switch the control mode of the water pump, remotely control the start and stop of the pump unit, and support various monitoring information, control information, alarm information Operation information storage and history query, generating various data reports and data curves. The monitoring system of the pump station belongs to the application of advanced Internet of things technology.

At present, there are 76 rainwater pump stations and 24 sewage pump stations in Hefei, which will be monitored by the control center in the future. Moreover, the control center is designed to meet the needs of signal acquisition and centralized monitoring of 150 pump stations at most, with a capacity expansion of 50% compared with the original control center. After completion, it can monitor all current drainage facilities in Hefei in real time, effectively monitor the working status of facilities, deal with abnormal conditions in time and reduce losses.
