Drainage pumping station control system, control method and single pump starting method
The invention relates to the technical field of control scheduling, and particularly provides a drainage pumping station control system, a control method and a single pump starting method. The input end of the multi-stage centrifugal water pump is connected with the output end of the water tank; the data acquisition device is used for acquiring a reservoir liquid level signal, a water tank liquid level signal, a water pump bearing temperature signal, a water pump motor temperature signal, a water outlet pressure signal and video image information; the PLC control unit is used for controlling the working state of the water pump; the method comprises the steps that the PLC control unit collects a pressure signal and judges whether the water outlet pressure value of the water pump reaches a starting pressure value or not; the PLC control unit collects liquid level information and calculates average liquid level information of the reservoir; sequentially starting the water pumps based on the average liquid level information. The invention aims to realize the technical effects of remotely controlling the drainage pumping station and avoiding faults caused by long-time operation of the water pumps, and solves the problem that a plurality of water pumps are simultaneously started to impact a power grid.
本发明涉及控制调度技术领域，尤其是提供一种排水泵站控制系统、控制方法及单泵启动方法，系统包括：蓄水池，其输出端连接有水箱；多级离心水泵，其输入端与水箱的输出端连接；数据采集装置，用于获取蓄水池液位信号、水箱液位信号、水泵轴承温度信号、水泵电机温度信号、出水压力信号、视频图像信息；PLC控制单元，用于控制水泵的工作状态；方法包括：PLC控制单元采集压力信号并判断水泵出水压力值是否达到启动压力值；PLC控制单元采集液位信息并计算蓄水池的平均液位信息；基于平均液位信息依次启动水泵。其目的在于，实现对排水泵站远程控制、避免水泵长时间运转产生故障的技术效果，解决了多台水泵同时启动，对电网冲击的问题。
