Abstract

This utility model relates to a water pump control system, addressing the safety hazards present in existing technologies when external devices are connected or multiple pumps are cascaded. The technical solution includes an electronic control unit, a power supply module electrically connected to the electronic control unit, and a communication module communicatively connected to the electronic control unit. The key feature is the inclusion of a first isolation module electrically and signal-connected to the electronic control unit, and a second isolation module electrically and signal-connected to the power supply module, communication module, and electronic control unit. The first isolation module isolates high-voltage electrical signals between the electronic control unit and the power supply module; the second isolation module isolates high-voltage electrical signals between the communication module and the electronic control unit; and the communication module is used for communication with external devices. Its effect is that the entire water pump control system is divided into three electrically isolated circuits through the isolation modules, achieving electrical isolation between high-voltage and low-voltage circuits, and between the water pump control system and external devices, thus achieving dual isolation.
