Abstract

The present disclosure discloses a door lock, a door lock controlling method and a door lock controlling device. The door lock includes a main controlling module, an unlocking module and a sensing module. The sensing module is configured to determine whether a human body is present within a first preset detection range; if yes, the main controlling module and the unlocking module are controlled to be powered on; and if no, the main controlling module and the unlocking module are controlled to be powered off. In the present disclosure, only the sensing module is in an operating state and other modules are not powered on when there is no user who is trying to open the door. Therefore, the power consumption of the door lock is reduced.

First claim

What is claimed is:

1. A door lock, comprising:
a main controlling module;
an unlocking module;
a sensing module; and
a timing module connected to the sensing module;
wherein the sensing module is configured to:
a) determine, by the sensing module, whether a human body is present within a first preset detection range;
b) in response to determining, by the sensing module, that a human body is present within the first preset detection range:
i) transmit, by the sensing module, a signal that causes the main controlling module and the unlocking module to be powered on; and
ii) send, by the sensing module, human body sensing information to the timing module while sensing that the human body is present within the first preset detection range; and

c) in response to receiving, by the sensing module, timeout information sent by the timing module that represents a determination that a human body is not present within the first preset detection range within a preset time period, control transmit, by the sensing module, a signal that causes the main controlling module and the unlocking module to be powered off; and

wherein the timing module is configured to:
a) record a first time point at which the human body sensing information is received by the timing module;
b) search whether previous human body sensing information was received before the first time point; and
c) in response to determining that previous human body sensing information was received before the first time point:
i) search for a second time point at which the previous human body sensing information was received; and
ii) in response to determining that a time difference between the first time point and the second time point is not greater than a time difference threshold, send first information to the sensing module, wherein the first information indicates that the time difference between adjacent two times of unlocking the door is not greater than the time difference threshold;

wherein the sensing module is further configured to send the first information to the main controlling module; and
wherein the main controlling module is configured to present the first information for communicating that another person opened or tried to open the door to avoid fright or collision between them.

2. The door lock according to claim 1 , wherein the main controlling module is connected to the unlocking module, and wherein the main controlling module is configured to:
receive, by the main controlling module, an unlocking instruction of a person who is trying to open a door sent by the unlocking module;
determine, by the main controlling module, whether unlocking information carried in the unlocking instruction is consistent with target unlocking information that is pre-stored in the main controlling module;
in response to determining, by the main controlling module, that the unlocking information carried in the unlocking instruction is consistent with the target unlocking information that is pre-stored in the main controlling module, control, by the main controlling module, the unlocking module to unlock; and
in response to determining, by the main controlling module, that the unlocking information carried in the unlocking instruction is not consistent with the target unlocking information that is pre-stored in the main controlling module, keep, by the main controlling module, the unlocking module in a locked state.

3. The door lock according to claim 1 , wherein the door lock further comprises a first switch connected between the main controlling module and the sensing module;
wherein the sensing module is specifically configured to control the first switch to be closed when sensing that the human body is present within the first preset detection range, and to control the first switch to be open when sensing that no human body is present within the first preset detection range.

4. The door lock according to claim 1 , wherein the door lock further comprises a second switch connected between the timing module and the sensing module,
wherein the sensing module is further configured to control the second switch to be closed when sensing that the human body is present within the first preset detection range, and configured to control the second switch to be open when receiving the timeout information.

5. The door lock according to claim 1 , wherein the sensing module is further configured to:
determine, by the sensing module, whether another human body is present within a second preset detection range at another side of the door lock when sensing that the human body is present within the first preset detection range;
in response to determining, by the sensing module, that another human body is present within the second preset detection range at an other side of the door lock when sensing that the human body is present within the first preset detection range, send, by the sensing module, second information of the other human body being present within the second preset detection range at the other side of the door lock to the main controlling module, wherein the other side of the door lock is opposite to a side where the sensed human body present within the first preset detection range is located; and
the main controlling module is further configured to:
present, by the main controlling module, the second information, wherein the second information comprises information of the other human body being present within the second preset detection range at the other side of the door lock.

6. The door lock according to claim 1 , wherein the main controlling module is further configured to:
determine, by the main controlling module, whether a user is resting inside a room when receiving an unlocking instruction; and
in response to determining, by the main controlling module, that the user is resting inside the room when receiving the unlocking instructions, present, by the main controlling module, third information, wherein the third information comprises information of the user being resting inside the room or do-not-disturb information set by the user.

7. The door lock according to claim 6 , wherein the main controlling module is configured to:
receive, by the main controlling module, images captured by an image capturing device mounted inside the room, and determine, by the main controlling module, whether the user is resting based on the images, or
search, by the main controlling module, whether the do-not-disturb information set by the user is pre-stored.

8. The door lock according to claim 1 , wherein the sensing module comprises at least one of a short-range capacitive sensing module, an infrared sensing module, and a human body sensing sensor.

9. The door lock according to claim 1 , wherein the unlocking module comprises at least one of a password unlocking module, a voice unlocking module, a wireless unlocking module, a fingerprint unlocking module, and a door lock motor unlocking module.

10. A door lock controlling method applied to a door lock, the method comprising:
determining, by a sensing module, whether a human body is present in a first preset detection range;
in response to receiving, by the sensing module, timeout information from a timing module that represents a determination that a human body is not present within the first preset detection range for a preset time period, transmitting, by the sensing module, a signal that causes a main controlling module of the door lock and an unlocking module of the door lock to be powered off; and
in response to determining, by the sensing module, that a human body is present within the first preset detection range:
transmitting, by the sensing module, a signal that causes the main cont
