[0078] In a power control circuit for an AI device in this embodiment, working power is connected by a power interface. When the first AI device U1 module 2 works normally, the first resistor R1 triggers the first power tube Q1 to turn on, and the connected power is transmitted to the power supply terminal VCC of the first AI device U1.

During the standby period, when the power of the backup power supply is lower than the under-voltage threshold set by the first power supply VCC1, the seventh resistor R7 and the eighth resistor R8, the second comparator A2 outputs a high level to control the third switch tube VT3 and the fourth switch tube VT4 to turn on, increase the under-voltage threshold, and at this time, the energy storage cycle of the backup power supply will be increased, and at the same time, the first logic chip U2 will output a low level, and at this time, the power will be supplied by the electric energy connected to the power interface again. When the power interface loses power, the second power tube Q2 will be turned on. When the backup power supply is fully charged, it will be normally powered by the backup power supply.
