The value of any signal, timing signal, or combination thereof will be greater than the set value, and these exceptions will be used as a basis for prompting the user.

After comparison, if the temperature is higher than the protection temperature value, the control unit 27 outputs a second warning signal.

2. The temperature sensing unit 23 senses the temperature inside the housing B (generally refers to the overall temperature generated by the operation of electronic components on the circuit substrate), and outputs a second temperature sensing signal to the control unit 27 . After comparison, if the temperature is higher than the protection temperature value, the control unit 27 outputs a second warning signal.

3. The power sensing unit 22 should sense the current value at the input end of the electric drive mechanism 12 and output a current signal to the control unit 27 . The control unit 27 outputs a second warning signal if the current value is higher than the protection current value after comparison.

4. The power sensing unit 22 should sense the current value at the input end of the electric drive mechanism 12 and output a current signal to the control unit 27 . The control unit 27 cooperates with the timing unit 24 to accumulate the time of the current signal (that is, the accumulated time for the power supply mechanism 11 to supply power to the electric driving mechanism 12). When the accumulated time is greater than the timeout value, a second warning signal is output.

<Power abnormality>

The power sensing unit 22 senses the remaining power of the power supply mechanism 11 and then outputs a power signal to the control unit 27 . The control unit 27 compares the preset low battery value, and if it is lower than the preset value, outputs a third warning signal to the backend status warning unit 40, allowing the backend status warning unit 40 to output yellow light so that the user can visually Notified of low battery.
