[0013] If the ECO virtual button for switching between high and low speeds switches from idle to high speed, then step S25 is executed.

[0014] S22, the handheld mobile smart terminal sends a generator idling signal to the controller U6 via Bluetooth. After the controller U6 receives the generator idling signal sent by the handheld mobile smart terminal through the Bluetooth chip U10, it proceeds to the next step.

[0015] S23, the high / low speed switching ECO signal terminal P20 / ANI0 of the controller U6 outputs the generator idle speed working signal, which turns on its opto-isolation tube U7, and the high / low speed switching ECO terminal ECO_OUT of the interface P3 outputs the generator idle speed working signal to the generator set.

[0016] After the generator set switches to idle speed operation, the unit sends the idle speed operation signal to the controller U6 via the serial communication level module. Upon receiving the idle speed operation signal, the high / low speed switching ECO indicator terminal P30 / INTP3 / SCK11 / SCL11 of the controller U6 illuminates the indicator light; the indicator light in the high / low speed switching ECO indicator button K2 also illuminates, indicating that the unit is in idle speed mode. Furthermore, the controller U6 sends a correction signal indicating that the unit is in idle speed mode to the handheld mobile smart terminal via the Bluetooth chip U10; then proceeds to the next step.

Upon receiving the high-speed operation signal, the controller U6 outputs an indicator light extinguishing signal at the high / low speed switching ECO indicator terminal P30 / INTP3 / SCK11 / SCL11; the indicator light on the high / low speed switching ECO indicator button K2 also turns off, indicating that the unit is in high-speed mode. Furthermore, the controller U6 sends a high-speed mode correction signal to the handheld mobile smart terminal via the Bluetooth chip U10, and proceeds to the next step.

[0031] S33, the restart signal terminal P120 / ANI19 of controller U6 outputs a restart recovery signal, which turns on its opto-isolation tube U9, and the restart signal terminal RST_OUT of interface P3 outputs a restart recovery signal to the unit inverter;

[0032] After the unit inverter restarts and resumes output, it sends a normal output signal to controller U6 via the serial communication level module. Upon receiving this signal, the restart indicator terminals P31 / TI03 / TO03 / INTP4 of controller U6 illuminate, and the indicator light on restart button K1 also illuminates, indicating that the inverter is now operating normally. Furthermore, controller U6 sends a calibration signal indicating that the unit is in normal inverter output mode to the handheld mobile smart terminal via Bluetooth chip U10, and then proceeds to the next step.

[0033] S34, after receiving the inverter normal output correction signal from the unit, the handheld mobile smart terminal determines the status of the restart virtual button:

[0034] If the restart virtual button is enabled, the state of the restart virtual button will not be switched, and step S31 will be executed;

[0038] After the unit inverter disconnects its output, the unit inverter sends a disconnection signal to the controller U6 via the serial communication level module. Upon receiving the disconnection signal, the indicator lights on the controller U6's restart indicator terminals P31 / TI03 / TO03 / INTP4 turn off; the indicator light on the restart indicator button K1 also turns off, indicating that the inverter is disconnected. Furthermore, the controller U6 sends a correction signal indicating that the unit is in inverter disconnection mode to the handheld mobile smart terminal via the Bluetooth chip U10, and then proceeds to the next step.

[0039] S37, after receiving the inverter disconnection output correction signal from the unit, the handheld mobile smart terminal determines the status of the restart virtual button:

[0040] If the restart virtual button is in the off state, then the state of the restart virtual button will not be switched, and step S31 will be executed;

[0041] If the virtual restart button is in the on state, then the virtual restart button will switch from the on state to the off state, and step S31 will be executed.

[0042] In a preferred embodiment of the present invention, step S2 further includes the following step:

[0043] S41, if the indicator light in the restart indicator button K1 is off, after pressing the restart indicator button K1, the restart terminal P137 / INTP0 of the controller U6 receives the restart recovery signal. After receiving the restart recovery signal, the restart signal terminal P120 / ANI19 of the controller U6 outputs the restart recovery signal, turning on its opto-isolation tube U9. The restart signal terminal RST_OUT of interface P3 outputs the restart recovery signal to the unit inverter. After the unit inverter restarts and recovers its output, the unit inverter sends the normal output working signal of the unit inverter to the controller U6 through the serial communication level module. After receiving the normal output working signal of the unit inverter, the restart indicator terminal P31 / TI03 / TO03 / INTP4 of the controller U6 outputs the indicator light signal; the indicator light in the restart indicator button K1 lights up, indicating that the inverter is now outputting normally. Furthermore, the controller U6 sends the unit is in the inverter normal output correction signal to the handheld mobile smart terminal through the Bluetooth chip U10; proceed to the next step.

[0044] If the indicator light in the restart indicator button K1 is lit, pressing the restart indicator button K1 will cause the restart terminal P137 / INTP0 of the controller U6 to receive a disconnect output signal. After receiving the disconnect output signal, the restart signal terminal P120 / ANI19 of the controller U6 will output a disconnect output signal, turning on its opto-isolation tube U9. The restart signal terminal RST_OUT of interface P3 will output a disconnect output signal to the unit inverter. After the unit inverter disconnects the output, the unit inverter will send the unit inverter disconnect output working signal to the controller U6 through the serial communication level module. After receiving the unit inverter disconnect output working signal, the restart indicator terminal P31 / TI03 / TO03 / INTP4 of the controller U6 will output an indicator light extinguishing signal. The indicator light in the restart indicator button K1 will turn off, indicating that the inverter is disconnected at this time. The controller U6 will also send a unit in inverter disconnected output correction signal to the handheld mobile smart terminal through the Bluetooth chip U10. Step S43 will then be executed.
