referring to fig. 1, the low-power-consumption intelligent door lock comprises a door lock control MCU, a capacitive touch keyboard, a fingerprint sensor, a non-contact IC card antenna, a BLE bluetooth module, a voice playing module, an OLED display screen, a door lock motor driving module, a battery power monitoring module and a door handle switch sensor, wherein the capacitive touch keyboard, the fingerprint sensor, the non-contact IC card antenna, the BLE bluetooth module, the voice playing module, the OLED display screen, the door lock motor driving module, the battery power monitoring module and the door handle switch sensor are all electrically connected with the door lock control MCU; the intelligent voice playing device is characterized by further comprising a loudspeaker, a door lock motor and a battery, wherein the loudspeaker is electrically connected with the voice playing module, the door lock motor is electrically connected with the door lock motor driving module, and the battery is electrically connected with the battery power monitoring module.
The low-power consumption standby method comprises the following steps:
(1) closing the door lock;
(2)5s, the door lock control MCU turns off the BLE Bluetooth module, the voice playing module, the OLED display screen, the door lock motor driving module and the battery electric quantity monitoring module, keeps the connection of the capacitive touch keyboard, the fingerprint sensor and the non-contact IC card antenna, and is in a low power consumption state at the moment; here, the time to enter the low power consumption state may be set as required.
(3) When the door lock control MCU monitors that the door handle switch sensor does not transmit signals for 48 hours continuously, the capacitive touch keyboard, the fingerprint sensor and the non-contact IC card antenna are turned off, and the door lock control MCU is in an extremely low power consumption state at the moment; here, the time to enter the extremely low power consumption state may be set according to the demand.
(4) When a user rotates the door handle, the door handle switch sensor transmits a signal to the door lock control MCU to wake up the door handle switch sensor, and the door lock control MCU connects the capacitive touch keyboard, the fingerprint sensor and the non-contact IC card antenna;
(5) the user opens the door lock in a touch key mode, a fingerprint mode or a non-contact card mode.
Further comprising a step (6) following step (5), wherein: the door lock control MCU connects the BLE Bluetooth module, the voice playing module, the OLED display screen, the door lock motor driving module and the battery electric quantity monitoring module.
After the intelligent door lock is awakened, all functional modules are in a working state, and the dynamic current is less than 200 mA. If the door lock is not operated within more than 5s, the door lock enters a low-power consumption dormant state, only the capacitive touch keyboard, the fingerprint sensor and the non-contact IC card antenna are in a low-power consumption scanning state, keyboard input, fingerprints and the IC card are continuously scanned, and the current is less than 100 uA.
The invention relates to a technology realizing point that when an intelligent door lock is not used for more than 48h (2 days), the door lock enters an extremely low power consumption mode, the keyboard function, the fingerprint function and the IC card function of the intelligent lock are all closed in the mode, the door lock controls an MCU to enter a lowest power consumption state, the current of the lock working in the extremely low power consumption mode is less than 1uA, the standby time of the intelligent lock can be greatly prolonged, and particularly the lock with low use frequency is adopted.

The calculation is carried out according to the capacity of a common dry battery on the market of 2000mAh, and the calculation method under an ideal state is as follows:
the normal sleep mode current is 100uA:
the number of standby years is: (2000/0.05) ÷ 24/365 ≈ 2.3 years
The current of the extremely low power consumption mode is 1uA:
the number of standby years is: (2000/0.001) ÷ 24/365 ≈ 228 years
Compared with the traditional dormancy mode, the method can improve the standby time by nearly 100 times, and the standby service life of the lockset can be prolonged by about 3 times by adopting the technical invention because the service life of the common dry battery is 7 years.
