If main control module 1 damages, the user can't realize opening of intelligent lock through main control module 1's control, can press emergency button 28, awaken up vice control module 2, and make control switch 25 closed simultaneously, power supply that vice power module can be stable at this moment, the user can loosen emergency button 28, then the user can input the information of unblanking through touch button collection module 11 and fingerprint collection module, vice control module 2 obtains the information of unblanking after comparing with the user information in the storage module, if information comparison succeeds, vice control module 2 then control drive module drive intelligent lock and open.

If the voltage output by the main power supply module is lower than a preset voltage value (the preset voltage value is the lowest voltage value required by the main power supply module to open the intelligent lock), the auxiliary power supply module can be used for supplying power and the auxiliary control module 2 can be used for controlling the intelligent lock to open by pressing the emergency button 28.

After the secondary control module 2 controls the intelligent lock to be opened, the secondary control module 2 can control the control switch 25 to be switched off, so that the first line 26 is switched off, the secondary power supply module stops supplying power, and the secondary control module 2 also stops working and enters the sleep state again.
