[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] A portable generator set control unit includes a generator set panel module and an internal generator set module. The generator set panel module is equipped with a two-wire remote control terminal. The internal generator set module includes a wireless control module and a microcontroller unit. The two-wire remote control terminal is connected to the wireless control module, and the wireless control module is connected to the microcontroller unit. The two-wire remote control terminal sends control signals to the wireless control module, and the wireless control module transmits the received signals to the microcontroller unit. The microcontroller unit controls the generator set by receiving the signals.

[0029] exist Figure 4 and Figure 6In this configuration, the connector's LI_2Wireenable is connected to both the two-wire remote control terminal and the LI_2Wireenable terminal of the microcontroller unit. The generator set panel module also features an external AC power input terminal. The internal generator module includes an AC / DC charging module, which connects to the external AC power input terminal. When power is input to the external AC power input terminal, the AC / DC charging module charges the generator set.

[0030] Example 2

[0031] Based on Example 1, the generator set panel module in this embodiment is further provided with a selection unit, which is used to select the control mode of the generator set.

[0032] The selection unit is a two-way switch selector. When the switch selector selects the first channel, the generator set is controlled through the first control mode. When the selector selects the second channel, the generator set is controlled through the second control mode.

[0033] Figure 3 The AC / DC charging module includes an input rectifier circuit module, an isolation circuit module, and an output rectifier circuit module. The input rectifier circuit module is used to rectify the input voltage and transmit the rectified voltage to the isolation circuit module for high-frequency chopping modulation. The isolation circuit module is used to step down and isolate the voltage output and transmit the isolated output voltage to the output rectifier and voltage regulator circuit module to form a stable DC voltage.

[0034] exist Figure 2 In the process, for the switch selector, in the first channel, it is a 2-wire remote start / stop; in the second channel, it is a one-button start / stop + wireless remote start / stop. By making the selection, the conflict between unattended 2-wire remote start / stop and manual operation is avoided, which would cause the unit's start / stop function logic to become chaotic and abnormal.

[0038] The positive terminal of the AC / DC charging module is connected to the positive terminal of the starting battery, and the negative terminal of the AC / DC charging module is connected to the negative terminal of the starting battery, in order to charge the starting battery.

[0039] The wireless control module is connected to the starter battery, starter, internal combustion engine ignition system, display unit, and stepper motor, and controls the starter, internal combustion engine ignition system, display unit, and stepper motor through the wireless control module.

[0040] The 2-Wire remote start / stop solution includes alarm indicator lights for start failure and abnormal generator shutdown, which are used to remind users that there is an abnormality in the generator set and to prevent the portable generator set from continuing to start the generator set when it has run out of fuel and shut down, which could damage the starting device.
