[0071] Those skilled in the art will appreciate that all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. It should also be understood that terms such as those defined in a general dictionary should be understood to have meaning consistent with the meaning in the context of the prior art, and will not be idealized or excessive unless specifically defined as here. The formal meaning is explained.

Referring to FIG. 1, an embodiment of a door lock control method according to the present invention is provided. The method includes the following steps: [0073] Sl1, detecting whether a person is close to the door lock. When no one is close to the door lock, the process proceeds to step S12; when the person is locked by the near door, the process proceeds to step S13.

[0074] S12. The identity verification module that controls the door lock remains in a sleep state.

[0075] S13. Awakening the identity verification module of the door lock from the sleep state.

In the embodiment of the present invention, a proximity sensor is installed in the door lock, and the proximity sensor is used to detect whether a person is close to the door lock, and the proximity sensor may be an infrared sensor, an ultrasonic sensor, a laser sensor, a sound sensor, or the like.

[0077] In step S11, it can be detected whether the person is close to the door lock by:

[0078] Alternatively, it may be detected by an infrared sensor whether a person is close to the door lock. In some embodiments, first The infrared energy is detected by the infrared sensor, and then the detected infrared energy and the threshold value are compared to determine whether the detected infrared energy exceeds the threshold; when the detected infrared energy exceeds the threshold, it is determined that someone is close to the door lock; when the detected infrared light is detected If the energy does not exceed the threshold 吋, it is determined that no one is close to the door lock. Wherein, the threshold can be determined according to an empirical value or an experimental value.

[0079] In other embodiments, the infrared sensor is preferably a passive pyroelectric infrared probe, and the pyroelectric element of the probe is very sensitive to external infrared radiation (infrared radiation having a wavelength of about 10 micrometers). Upon receiving a change in the temperature of the infrared radiation of the human body, the charge balance is lost and the charge is released outward. Based on this principle, the passive pyroelectric infrared probe can detect whether someone is approaching by detecting the infrared rays emitted by the human body by about 10 microns. Further, in order to be sensitive only to the infrared radiation of the human body, a special Philippine filter can be covered on the radiation surface of the probe, and the infrared radiation of about 10 micrometers emitted by the human body can be enhanced by the Philippine filter and concentrated to the infrared induction. At the source, the interference of the environment is clearly controlled.

[0080] Alternatively, it may be detected by an ultrasonic sensor whether a person is approaching the door lock. Specifically, first, the ultrasonic wave is transmitted by the wave transmitter of the ultrasonic sensor, and then it is determined whether the wave receiver of the ultrasonic sensor receives the echo in the preset time; when the wave receiver of the ultrasonic sensor receives the back in the preset time Wave, it is determined that someone is close to the door lock; when the wave receiver of the ultrasonic sensor does not receive the echo in the preset time, it is determined that no one is close to the door lock. Wherein, the preset time can be determined based on empirical values or experimental values.

[0081] Alternatively, it is possible to detect whether a person is close to the door lock by a laser sensor. Specifically, first, the laser is emitted by the transmitter of the laser sensor, and then it is determined whether the receiver of the laser sensor receives the reflected laser light in the preset time; when the receiver of the laser sensor receives the reflection in the preset time zone The laser 吋 determines that someone is close to the door lock; when the receiver of the laser sensor does not receive the reflected laser 在 in the preset 吋, it is determined that no one is close to the door lock. Among them, the preset time can be determined according to the empirical value or the experimental value.

[0082] Alternatively, it may be detected by an acoustic sensor whether a person is close to the door lock. Specifically, the sound signal is first collected by the sound sensor, and then the sound signal is determined to meet the preset condition; when the sound signal satisfies the preset condition, it is determined that someone is close to the door lock; when the sound signal does not satisfy the preset condition, it is determined that no one is close to Door lock. [0083] The preset condition may be a volume condition. That is, comparing the volume of the collected sound signal with the preset volume, determining whether the volume of the collected sound signal exceeds the preset volume; when the preset volume is exceeded, the determination meets the preset condition, and it is determined that someone is close to the door lock; If the preset volume is not exceeded, it is determined that the preset condition is not met, and it is determined that no one is close to the door lock.

[0084] The preset condition may also be a sound matching condition. That is, comparing the characteristics of the collected sound signal with the preset features, and determining whether the characteristics of the collected sound signal match the preset features; when the two match, the determination meets the preset condition, and it is determined that someone is close to the door lock; If the two do not match, the judgment does not satisfy the preset condition, and it is determined that no one is close to the door lock.

It will be understood by those skilled in the art that, in addition to the above-listed solutions, other methods in the prior art may be used to detect whether a person is approaching, and the present invention will not be repeated here.

[0086] In step S12, when no one is close to the door lock, the control identity verification module remains in the sleep state. Specifically, when the identity verification module is currently in the working state, the control identity verification module is switched from the working state to the sleep state; when the identity verification module is currently in the dormant state, no operation is performed, and the identity verification module remains in the dormant state. Specifically, the identity verification module can be put into a sleep state by powering down the authentication module.

[0087] In step S13, when someone approaches the door lock, the identity verification module is woken up from the sleep state, so that the identity verification module enters the working state from the sleep state, and the shackle person is authenticated. In a specific implementation, the identity verification module can be brought into a working state from a sleep state by supplying power to the identity verification module.

[0088] The identity verification module in the embodiment of the present invention may be one or at least two of a biometric identification module such as a fingerprint identification module, a face recognition module, a voiceprint recognition module, an iris recognition module, and a scleral recognition module. The non-biological feature recognition module, such as a password verification module, may of course be used in the present invention.

[0089] A door lock control method according to an embodiment of the present invention, in a specific implementation, a proximity sensor may be added to the door lock

(such as infrared sensors) and low-power circuits, proximity sensors connect the processor's AD 10 pins, low-power circuits to connect processors and authentication modules (such as fingerprint recognition modules). By default, the FET (MOSFET) in the low-power circuit is not turned on, causing the authentication module and the power supply to be in a sleep state, preventing the authentication module from being in a working state and reducing power consumption. Proximity sensor detection When someone approaches the door lock, the proximity sensor inputs a high level to the AD10 pin of the processor. After the AD 10 pin of the processor receives a high level, the FET in the low-power circuit is controlled to be high. Turns on, thereby powering the authentication module, and waking up the authentication module to implement the authentication function.
