when the power pump body (210) idles, the controller (110) controls the power pump body (210) to stop through the relay (220).
10. The control method according to claim 8, wherein the dosing control includes:
writing a target fuel volume to be filled into the controller (110) through the touch screen (600);
the controller (110) controls the power pump body (210) to start through the relay (220);
the flow monitoring assembly (300) monitors the fuel flow value output by the power pump body (210) in real time and transmits the flow value to the controller (110);
the controller (110) performs accumulated calculation on the flow value output by the power pump body (210) and stores the flow value;
when the accumulated value reaches the target fuel volume, the controller (110) controls the power pump body (210) to stop through the relay (220);
the quantitative oiling control further comprises:
the liquid level measuring assembly (500) measures the actual liquid level height in the fuel tank in real time and transmits the actual liquid level height to the controller (110);
the controller (110) compares the actual liquid level height to a liquid level threshold;
when the actual liquid level height reaches the liquid level threshold value, the controller (110) controls the power pump body (210) to stop through the relay (220).
