Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

The invention discloses an unlocking control method of an intelligent door lock, which is applied to unlocking of the intelligent door lock and mainly comprises the following steps:

step S1, receiving a first signal fed back by the human body sensor and enabling the intelligent door lock to enter an awakening state;

step S2, receiving a second signal fed back by the voice receiving module, and judging whether the second signal is matched with a prestored third signal;

and step S3, when the intelligent door lock is in the awakening state and the second signal is matched with the third signal, controlling the motor assembly 5 of the intelligent door lock to work and unlock.

In step S1, the main control module of the intelligent door lock receives a first signal fed back by the human body sensor. In this embodiment, the human body sensor may be an infrared sensor module, an ultrasonic sensing module, or the like. Wherein the infrared sensor module can be one of the pyroelectric infrared sensor module 8 or the geminate transistor infrared detection module 10. Referring to fig. 3 and 4, the infrared sensor module is a pyroelectric infrared sensor module 8 or a pair-tube infrared detection module 10. When infrared sensor module is heat release infrared sensor module 8, when someone is close to intelligent lock, heat release infrared sensor module responds to human temperature at the response within range, sends electronic signal, transmits host system's main control chip. When infrared sensor module is geminate transistor infrared detection module 10, geminate transistor infrared detection module 10 has infrared emitter to send infrared light to wear out from lens printing opacity district, and when the human body was close to, infrared reflection passed from printing opacity district and absorbed by the receiver, and the receiver sends electronic signal this moment, transmits host system's main control chip. And when the main control chip receives the electronic signal, the system is awakened and powered on.

In this embodiment, can be in the position direct replacement installation ultrasonic wave response module of former infrared sensor module when substituting infrared sensor module for ultrasonic wave response module. Further, in order to further improve the stability and the security of the system, the infrared sensor module and the ultrasonic sensor module can be installed at the same time, wherein the main control module can enable the intelligent door lock to enter the awakening state when receiving the first signal fed back by the infrared sensor module or the ultrasonic sensor module, or the main control module can also enable the intelligent door lock to enter the awakening state when receiving the first signal fed back by the infrared sensor module and the ultrasonic sensor module at the same time. In step S2, the voice receiving module 9 receives an unlocking instruction sent by the user, such as "open door", converts the unlocking instruction into an electrical signal, i.e., a second signal, after receiving the unlocking instruction sent by the user, and then matches the second signal with a prestored third signal. A user only needs to input a corresponding unlocking instruction in advance before use, repeated input is not needed in subsequent use, and the two signals are compared through an algorithm during identification to judge whether the two signals are matched. In the prior art, various algorithms are used to realize corresponding judgment, and therefore are not described in detail.

In step S3, the smart door lock is unlocked only when both conditions are satisfied, so that the security of the smart door lock can be improved.

In this embodiment, it can be seen that in the unlocking control method of the present invention, the main control module receives the first signal and the second signal fed back by different modules, and when there is no first signal, the intelligent door lock is dormant, so that energy consumption can be saved and the working time of the intelligent door lock can be prolonged; the safety of the door lock is improved by unlocking when two conditions of the first signal and the second signal are met.

In this embodiment, after the intelligent door lock enters the wake-up state, the control method further includes: through suggestion module suggestion user intelligence lock entering wake-up state, the suggestion module includes pilot lamp and/or voice transmission module, and is specific:

Or, the voice sending module is controlled to send out a reminding voice, so that the user obtains the information that the intelligent door lock enters the awakening state, and sends an unlocking instruction to the voice receiving module 9 after receiving the reminding voice.

Or, the indicating lamp 7 of the intelligent door lock is controlled to work and the voice sending module is controlled to send voice prompt, so that a user can obtain information that the intelligent door lock enters the awakening state and send an unlocking instruction to the voice receiving module 9 after receiving the prompt voice.

Some disabled people such as amblyopia, blindness, deafness and the like exist among users using the intelligent door lock. When the users use the intelligent door lock, some auxiliary designs are needed to help disabled people to identify the state of the intelligent door lock. It should be noted that, the unlocking conditions of the two smart door locks are designed to ensure the safety of the smart door locks, so that certain convenience is sacrificed, the inventor believes that even if the disabled uses the smart door locks, the safety still needs to be the end of the convenience, and if only one unlocking condition is set, the safety of the smart door locks is greatly reduced. For example, only a sensor is arranged for unlocking, if a user only walks to the door without going out, and the intelligent door lock is unlocked, potential safety hazards exist, and life and property losses of the user are caused.

For some users, certain amblyopia exists, and it is not enough that only the indicator light 7 is lighted at this time, so that the user can more easily receive the state of the intelligent door lock by making the indicator light 7 flash to enhance the identifiability of the signal, or the user can know the state of the intelligent door lock by setting voice prompt under the condition that the hearing of the user is normal and the eyesight of the user is not good. The two modes can be used simultaneously, and one of the two modes can be selected for use according to requirements.
