[0033] An embodiment of the present application provides a door lock control method, which is applied to a door lock and is specifically executed by a processor of the door lock when running a computer program with corresponding functions.

[0034] In application, the door lock may include at least one sensor or be connected to at least one external sensor for detecting the distance between the target object in the room and the door lock and the residence time of the target object around the door lock. The door lock described in the embodiments of the present application does not constitute a limitation on the door lock, and the door lock may include more or fewer components, or combine certain components, or arrange the components differently.

[0035] like Figure 1 As shown, the door lock control method provided in the embodiment of the present application includes the following steps S101 to S104:

[0036] Step S101: When the door lock is closed, detect whether a target object in the room is within a first distance range of the door lock.

[0037] In the application, the target object can be a living object such as a human body or a pet, or a movable device such as an automatic guided vehicle or a mobile robot. That is, the door lock control method can be applied not only to indoor unlocking scenarios in home places, but also to indoor unlocking scenarios in factories, office buildings, stadiums and other places.

[0038] In one embodiment, step S101 includes:

[0039] The first sensor detects whether the indoor target object is within the first distance range of the door lock.

[0040] In application, when the door lock is closed, a first sensor arranged on the door body can be used to detect whether the target object is within a first distance range. The first sensor can be a part of the door lock or an external device that is communicatively connected to the door lock. In a first application scenario of the first sensor, the sensing range of the first sensor can be set to a first distance range, that is, as long as the first sensor senses the target object, it can be considered that the target object is within the first distance range of the door lock. For this application scenario, the first sensor can be a capacitive or resistive proximity sensor, a passive infrared sensor (Passive Infra-Red sensor, PIR), etc., which does not actively emit a detection signal and only generates a sensing signal after sensing the target object. Specifically, when the target object is a living body, the first sensor can be a passive infrared sensor; in a second application scenario of the first sensor, the distance between the target object and the door lock can be detected by the first sensor, and then the distance is sent to the processor of the door lock, and the processor determines whether the distance is within the first distance range. For this application scenario, the first sensor can be a photoelectric proximity sensor, an active infrared sensor, an ultrasonic sensor or a laser ranging sensor, etc., which actively emits a detection signal and generates a sensing signal after detecting the detection signal reflected by the human body. Specifically, when the target object is a living body, the first sensor can be an active infrared sensor.

[0041] In the application, for the first application scenario of the first sensor, the first distance range is a fixed range determined by the detection range of the first sensor. For the second application scenario of the first sensor, the first distance range can be set by the user according to the range of activities around the door lock when the user needs to go out, for example, [0cm, 100cm].

[0042] In one embodiment, for the second application scenario of the first sensor, before step S101, the following steps are included:

[0043] Receiving a first distance range setting instruction sent by a user;

[0044] According to the first distance range setting instruction, the first distance range is set.

[0045] In the application, the first distance range can be customized by the user according to actual needs or the default setting of the door lock when it leaves the factory can be adopted. The user can directly input the first distance range setting instruction through the human-computer interaction device of the door lock. The human-computer interaction device of the door lock may include at least one of a physical button, a touch sensor, a gesture recognition sensor and a voice recognition unit, so that the user can input the first distance range setting instruction through the corresponding touch mode, gesture control mode or voice control mode.

[0046] In the application, the physical buttons and touch sensors can be set at any position of the door lock, for example, the control panel of the door lock. The touch mode of the physical buttons can be pressing or toggling. The touch mode of the touch sensor can be pressing or touching, etc. The gesture recognition sensor can be set at any position of the door lock, and the gestures used to control the door lock can be customized by the user according to actual needs or adopt the factory default settings. The voice recognition unit can include a microphone and a voice recognition chip, or it can only include a microphone and the voice recognition function is implemented by the processor of the door lock. The voice used to control the door lock can be customized by the user according to actual needs or adopt the factory default settings.

[0047] In the application, the user can also control the user device to send the first distance range setting instruction to the door lock through any human-computer interaction method supported by the user device. The user device can be a remote control, a wired controller, a mobile phone, a smart bracelet, a tablet computer, a laptop computer, a netbook, a personal digital assistant (PDA), or other electronic device with wired or wireless communication functions that can communicate with the door lock. The embodiment of the present application does not impose any restrictions on the specific type of the user device. The human-computer interaction method supported by the user device can be the same as that of the door lock, and will not be repeated here.

[0048] Step S102: When the target object is within a first distance range of the door lock, detecting the distance between the target object and the door lock;

[0049] Step S103: when the target object is within a second distance range of the door lock, detecting the residence time of the target object within the second distance range of the door lock, where the second distance range is a subset of the first distance range;

[0050] Step S104: when the target object stays within the second distance range of the door lock for a period of time within the first time range, unlock the door lock.

[0051] In the application, when the target is within the first distance range of the door lock, it can be preliminarily determined that the target has the intention to go out, but the target may just pass by the door lock. Therefore, it is necessary to further detect the distance between the target and the door lock and the time it stays around the door lock to further determine the target's intention to go out. When it is determined that the target really needs to go out according to these judgment conditions, the door lock is opened. If the door lock itself is open, no operation is performed on the switch state of the door lock. By setting the three judgment conditions with a progressive relationship, namely the first distance range, the second distance range and the first time range, the door lock can be opened only when it is determined that the target really needs to go out, avoiding the target passing by the door lock, staying in front of the door lock for a short time or staying in front of the door lock for a long time, and falsely triggering the door lock to open. The second distance range is a subset of the first distance range. The second distance range is set according to the activity range of the target to prepare for going out around the door lock, for example, [30cm, 100cm]. The first time range is set according to the length of time the target prepares for going out around the door lock, for example, [2S, 30S).

[0052] In one embodiment, step S102 includes:

[0053] Detecting the distance between the target object and the door lock by a second sensor;

[0054] Step S103 includes:

[0055] The residence time of the target object within the second distance range of the door lock is detected by the second sensor.

[0056] In application, the distance between the target and the door lock and the residence time of the target around the door lock can be detected by a second sensor arranged on the door body. The second sensor can be a part of the door lock or an external device connected to the door lock. The distance between the target and the door lock is detected by the second sensor, and then the distance is sent to the processor of the door lock, which determines whether the distance is within the second distance range. The second sensor can be an active sensor that actively emits a detection signal, such as a photoelectric proximity sensor, an active infrared sensor, an ultrasonic sensor, or a laser ranging sensor, and generates an induction signal after detecting the detection signal reflected by the human body. Specifically, the second sensor can be a laser ranging sensor.

[0057] In one embodiment, before step S102, the following steps are included:

[0058] receiving a second distance range setting instruction sent by a user;

[0059] Setting the second distance range according to the second distance range setting instruction;

[0060] Before step S103, the following steps are included:

[0061] receiving a first time range setting instruction sent by a user;

[0062] According to the first time range setting instruction, the first time range is set.

[0063] In the application, the second distance range and the first time range can be customized by the user according to actual needs or the default settings of the door lock when it leaves the factory can be used. The way in which the door lock receives the second distance range setting instruction and the first time range setting instruction can be the same as the way in which the door lock receives the first distance range setting instruction, which will not be repeated here.

[0064] like Figure 2 As shown, in one embodiment, after step S101, the method further includes:

[0065] Step S105: When the target object is not within the first distance range of the door lock, the door lock is not opened.

[0066] In the application, when the target object is not within the first distance range of the door lock, it is determined that the target object has no intention of going out, and the door lock is not opened and maintained closed.

[0067] like Figure 3 As shown, in one embodiment, after step S103, the method further includes:

[0068] Step S106: When the target object stays within the second distance range of the door lock for a period of time within a second time range, the door lock is not opened, and the upper limit value of the second time range is less than the lower limit value of the first time range.

[0069] In the application, when the distance between the target object and the door lock satisfies the first distance range and the second distance range respectively, but the stay time is within the second time range, it can be determined that the target object has no need to go out, but just stays in front of the door lock for a short time, and the door lock is not opened at this time. The upper limit of the second time range is set to a shorter time according to actual needs, for example, 1S, and correspondingly, the second time range can be (0S, 1S).

[0070] In one embodiment, before step S106, the following steps are included:

[0071] receiving a second time range setting instruction sent by a user;

[0072] The second time range is set according to the second time range setting instruction.

[0073] In the application, the second time range can be customized by the user according to actual needs or the default setting of the door lock when it leaves the factory can be adopted. The way in which the door lock receives the second time range setting instruction can be the same as the way in which the door lock receives the first distance range setting instruction, which will not be repeated here.

[0074] like Figure 4 As shown, in one embodiment, after step S102, the method further includes:

[0075] Step S107: When the target object is within a third distance range of the door lock, the door lock is not opened, and the upper limit value of the third distance range is less than the lower limit value of the second distance range.

[0076] In the application, the upper limit of the third distance range is set to be smaller than the lower limit of the second distance range. When the target is within the third distance range of the door lock, it indicates that the target is close to the door lock. It may be standing at the door and looking outside (for example, looking at the peephole), or it may be passing by the door without the need to go out. Therefore, the door lock is not opened. The third distance range is set with reference to the lower limit of the second distance range, for example, (0cm, 20cm).

[0077] In one embodiment, before step S107, the following steps are included:

[0078] receiving a third distance range setting instruction sent by a user;

[0079] The third distance range is set according to the third distance range setting instruction.

[0080] In the application, the third distance range can be customized by the user according to actual needs or the default setting of the door lock when it leaves the factory can be adopted. The way in which the door lock receives the third distance range setting instruction can be the same as the way in which the door lock receives the first distance range setting instruction, which will not be repeated here.

[0081] like Figure 5 As shown, in one embodiment, the door lock control method provided by the embodiment of the present application further includes the following steps S108 to S111:

[0082] Step S108: When the door lock is opened, detect whether the target object in the room is outside the first distance range of the door lock.

[0083] In the application, for the application scenario where the door lock is open and the target is indoors, it is necessary to determine whether the target still needs to go out. If not, the door lock needs to be closed to ensure access security. The first sensor can be used to detect whether the target is outside the first distance range of the door lock. In the first application scenario of the first sensor, when the first sensor does not sense the target, it can be considered that the target is outside the first distance range of the door lock; in the second application scenario of the first sensor, the first sensor can detect the distance between the target and the door lock, and then send the distance to the processor of the door lock, which determines whether the distance is outside the first distance range.

[0084] Step S109: when the target object is outside the first distance range of the door lock, detecting the distance between the target object and the door lock;

[0085] Step S110: when the target object is within the fourth distance range of the door lock, detecting the residence time of the target object within the fourth distance range of the door lock, wherein the lower limit value of the fourth distance range is greater than the upper limit value of the second distance range;

[0086] Step S111: When the residence time of the target object within the fourth distance range of the door lock is within the third time range, closing the door lock, and the lower limit value of the third time range is greater than the upper limit value of the first time range.

[0087] In the application, when the target object is outside the first distance range of the door lock, it can be preliminarily determined that the target object has no intention to go out, but in order to further determine, it is necessary to further detect the distance between the target object and the door lock and the residence time around the door lock to further determine the target object's intention to go out. When it is determined based on these judgment conditions that the target object does not really need to go out, the door lock is closed. If the door lock itself is closed, no operation is performed on the switch state of the door lock. By setting the first distance range, the fourth distance range and the third time range, three judgment conditions with a progressive relationship, the door lock can be closed only when it is determined that the target object does not really need to go out, avoiding the door lock from being mistakenly triggered to close when the target object still needs to go out, causing the door lock to be opened again, and by automatically closing the door lock when it is determined that the user does not really need to go out, access control security can be guaranteed. The lower limit value of the fourth distance range is greater than the upper limit value of the second distance range, which is a longer distance. The fourth distance range is set according to the activity range of the target object outside the door lock when it does not need to go out, for example, (100cm, +∞). The lower limit of the third time range is greater than the upper limit of the first time range, which is a longer time length. The third time range is set according to the time length of the target object's activity range outside the door lock when it does not need to go out, for example, (30S, +∞).

[0088] In one embodiment, before step S110, the following steps are included:

[0089] receiving a fourth distance range setting instruction sent by a user;

[0090] Setting the fourth distance range according to the fourth distance range setting instruction;

[0091] Before step S111, the following steps are included:

[0092] receiving a third time range setting instruction sent by a user;

[0093] The third time range is set according to the third time range setting instruction.

[0094] In the application, the fourth distance range and the third time range can be customized by the user according to actual needs or the default settings of the door lock when it leaves the factory can be used. The way in which the door lock receives the fourth distance range setting instruction and the third time range setting instruction can be the same as the way in which the door lock receives the first distance range setting instruction, which will not be repeated here.

[0095] like Figure 6 As shown, a schematic diagram of the distance range around a door lock is shown as an example.

[0096] The door lock control method provided in the embodiment of the present application can automatically open the door lock when it is detected that the target object has a need to go out, and automatically close the door lock when it is detected that the target object has no need to go out, without the need for any manual operation.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
