The unit control module controls the diesel generating set in two modes, namely a manual mode and an automatic mode.
When the diesel generating set needs to be manually started, the set control module is adjusted to a manual mode, a start key is pressed to start the diesel generating set, after the set control module receives a start instruction issued by the monitoring terminal, the set control module simultaneously supplies power to the starting motor and the diesel engine ECU, and the starting motor operates to drive the diesel engine to synchronously operate. The ECU of the diesel engine is electrified to control the oil nozzle to spray oil. After the diesel generating set is started successfully, the set control module stops supplying power to the starting motor, the starting motor stops running, and power is continuously supplied to the diesel engine ECU to ensure that the diesel generating set runs. When the diesel generating set stops operating, a stop key is pressed, the set control module receives a stop instruction and sends the stop instruction to the diesel engine ECU, the ECU controls oil injection to stop oil injection, and the set control module cuts off power to the diesel engine ECU after the diesel generating set stops operating, so that stop is finished.

The ECU of the diesel engine is electrified to control the oil nozzle to spray oil. After the diesel generating set is started successfully, the set control module stops supplying power to the starting motor, the starting motor stops running, and power is continuously supplied to the diesel engine ECU to ensure that the diesel generating set runs. And the unit control module continuously monitors the phase voltage, the line voltage, the frequency and the phase sequence of the mains supply in real time in the running process of the diesel generating set.
