Control system and method for non-negative pressure water supply equipment
The invention discloses a control system and method for non-negative pressure water supply equipment. The system comprises a water inlet pressure sensor, an electric valve, a flow meter, a first water pump and a water supply controller; the water supply controller is connected with the water inlet pressure sensor, the electric valve and the first water pump; the water supply controller is used for receiving a pressure signal of the water inlet pressure sensor and a flow signal of the flow meter; and when the pressure signal value of the water inlet pressure sensor is larger than a preset first pressure value and the flow signal value of the flow meter is larger than a preset first flow value, the electric valve is controlled to be opened, the first water pump is controlled to be started to work, and the opening degree of the electric valve is controlled to be in positive correlation change along with the signal value of the water inlet pressure sensor. The situation that water utilization of a user is affected due to frequent starting and stopping of the first water pump is avoided, and the service life of the first water pump can be prolonged.
本发明公开一种无负压供水设备的控制系统及其方法，该系统包括：进水压力传感器、电动阀、流量计、第一水泵和供水控制器；所述供水控制器分别与所述进水压力传感器、电动阀和第一水泵连接；所述供水控制器用于接收所述进水压力传感器的压力信号以及所述流量计的流量信号，当所述进水压力传感器的压力信号值大于预设的第一压力值且所述流量计的流量信号值大于预设的第一流量值时，控制所述电动阀开启以及控制所述第一水泵启动工作，并控制所述电动阀的开启程度随所述进水压力传感器的信号值呈正相关变化。实现避免因为第一水泵频繁启停而影响用户用水，并且可以延长第一水泵的使用寿命。
