AI Technical Summary
In the existing technology, starting the device with two buttons increases the number of buttons and complicates the startup process.
The system employs a linkage control circuit, utilizing a self-resetting button to control the on/off state and duration of the signal line. This allows for the linkage power-on of the battery pack module and the control module via a single button, reducing the number of buttons and simplifying the startup operation.
This simplifies the device startup process and reduces the number of buttons, while improving device reliability and ease of maintenance.
