The power down detection circuit 30 is used for power down detection. The capacitance circuit 20 and the power down detection circuit 30 are electrically connected to a power supply. The controller 40 electrically connects the 5G module 10, the capacitance circuit 20, and the power down detection circuit 30.
The capacitor circuit 20 is used to store power and can continue to power the device for more than 200 milliseconds when the power is lost. The power down detection circuit 30 is used for power down detection, and when power down is detected, transmits power down information to the controller 40.
