Design method of intelligent water pump controller of substation

The invention discloses a design method of an intelligent water pump controller of a substation. According to the method, a main control module, an input acquisition module, an alternating current sampling module, a relay external control module, a relay output module, a wireless communication module, a serial communication module, an Ethernet module, a display module and a power supply module are mainly included. The water pump controller collects in-station water level information and water pump operation information through the input acquisition module, the alternating current sampling module and the serial communication module, and can be displayed locally through a display interface. Response is made in time when water level abnormality is detected, and a water pump is automatically controlled or manually controlled according to a set control mode. When the water pump operates abnormally, the operating water pump is disconnected and a standby water pump is started, hidden dangers of power equipment and a
