Description

Technical Field

[0001] The present application relates to the technical field of smart door locks. Background Art

[0002] The inner door lock of a smart door lock refers to the part of the smart door lock located indoors. Figure 1 The inner door lock is located indoors. Usually, the mechanical structure of the inner door lock includes a door handle 2, an anti-lock knob 4, etc., and the electronic part includes a visual cat-eye screen and a lithium battery compartment 1, an electronic locking key 3, etc.

[0003] When there is no automatic sensing lighting system in the user's room, the user cannot get lighting in time when entering the door. For example, when the user goes out at night, he cannot get lighting after turning off the room lights before going out.

[0004] Especially when there is a power outage in the user's community at night or a circuit failure in the user's home at night, when the city power is off, general household appliances cannot provide indoor lighting, including smart door locks currently on the market.

[0005] How to provide users with timely and accurate lighting is the technical problem to be solved by this application. Summary of the invention

[0006] The purpose of this application is to provide a smart door lock to provide users with timely and accurate lighting.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions.

[0008] The embodiment of the present application provides a smart door lock, including a rotating mechanism and a camera, wherein a lamp body is fixed around the camera;

[0009] The lamp body and the camera are both installed on the rotating mechanism so that the lamp body rotates together with the camera.

[0010] Compared with the prior art, this application has the following beneficial effects:

[0011] The smart door lock provided in the embodiment of the present application is integrated with a rotatable lighting system, which can provide timely and accurate lighting for the user when the user is near the door.

[0012] Optionally, the lamp body and the camera are arranged in an inner door lock inside the door, and the lamp body is used for lighting inside the house.

[0013] Optionally, the smart door lock also includes a battery; the battery is used to power the lamp body.

[0014] The beneficial effect of providing a battery is that when a power outage occurs in the user's community at night or a circuit failure occurs in the user's home at night, the lamp body can be used for emergency lighting in the house when the city power is cut off.

[0015] Optionally, the camera rotates following the movement of the person, and the light of the lamp body follows the movement of the person, which has the beneficial effect of making the lighting provided by the smart door lock more accurate.

[0016] Optionally, the camera is always on, and the position information of the person is obtained by analyzing the captured images, and the camera rotates based on the position information of the person.

[0017] Optionally, the smart door lock further includes a radar module and a controller;

[0018] The radar module is used to send a first signal to the controller when detecting an active target in a set space;

[0019] The controller is used for sending a second signal to the camera after receiving the first signal;

[0020] The camera is used to judge the humanoid state after receiving the second signal, and send the humanoid state parameters to the controller;

[0021] The controller is also used to send a request angle signal to the radar module when the humanoid state parameter is true;

[0022] The radar module is further used to detect the azimuth angle of the human figure after receiving the request angle signal, and send the azimuth angle of the human figure to the controller;

[0023] The controller is also used to control the rotation of the rotating mechanism according to the orientation angle of the human figure.

[0024] The controller's function of controlling the rotation mechanism to rotate can enable the camera and the lamp body to aim at a person, making it easier for the user to use.

[0025] Optionally, the camera is used to determine the state of a human figure and generate human figure state parameters;

[0026] The camera is also used to perform face recognition on the human figure when the human figure status parameter is true, and determine whether the human figure is a legal registered user.

[0027] The beneficial effect of the camera's face recognition function is that it can detect unauthorized users and improve security. For example, when a thief passes through or walks out of a door, it can be discovered and alerted in time.

[0028] Optionally, when the human figure is an unregistered user, the smart door lock sends an alarm message to the user control terminal (for example, a mobile phone as the user control terminal, through an app), and the user control terminal provides the user with options including adding the unregistered user as a legitimate user or alarming.

[0029] Optionally, when the humanoid state parameter is false, the power of the camera is turned off and the radar module enters a standby state;

[0030] The standby state refers to a state in which human activity detection is continuously performed without performing distance detection or angle detection.

[0031] The radar module only needs to detect the azimuth angle of the human figure when the human figure status parameter is true. If the moving target is not a human, there is no need to continue detecting, thereby saving power consumption.

[0032] Optionally, the smart door lock further includes a light sensor, a radar module and a controller;

[0033] The light sensor is used to detect the ambient light intensity;

[0034] The camera is used to judge the humanoid state and send the humanoid state parameters to the controller;

[0035] The controller is also used to send a request distance signal to the radar module when the humanoid state parameter is true;

[0036] The radar module is also used to detect the distance of the human figure after receiving the request distance signal, and send the distance of the human figure to the controller;

[0037] The controller is also used to control the brightness of the lamp body according to the distance of the human figure and the light intensity.

[0038] The brightness of the lamp can be flexibly controlled according to the light intensity in the environment to avoid excessive brightness or start the lamp when the light intensity is sufficient to save energy.

[0039] When the distance of the human figure is far, the brightness of the lamp body can be appropriately increased to make the light effective at a farther position, which is convenient for users to use.

[0040] Optionally, the controller is used to enable the camera to rotate following the movement of the person, and to focus the light of the lamp body on the space in front of the person.

[0041] Optionally, the lamp body includes a plurality of partition lamps with different irradiation directions;

[0042] The controller is used to control the brightness of each of the partition lights according to the orientation angle, distance and light intensity of the human figure.

[0043] The partition lamp can cooperate with the rotating mechanism to better adjust the light output angle and expand the range of the light output angle.

[0044] Optionally, the controller is used to determine the space in front of the person through the radar module or the camera, and control the brightness of each of the partition lights to concentrate on the space in front of the person.

[0045] Focusing the light on the space in front of a person rather than on the person himself makes it more convenient for users.

[0046] Optionally, the partition lights are partitioned along the left and right directions;

[0047] The controller is used to control the partition lights on the left to dim and the partition lights on the right to brighten when it detects that the person moves from left to right; when it detects that the person moves from right to left, it controls the partition lights on the right to dim and the partition lights on the left to brighten.

[0048] The left and right partitions can effectively adjust the light output direction in the horizontal direction, and the structure is simple and easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described in the drawings here can be arranged and designed in various different configurations.

[0070] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0071] In the description of this application, it should be noted that:

[0072] Relational terms such as first and second, etc. are used merely to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any such actual relationship or order between these entities or operations;

[0073] “Connection” should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0074] Existing smart door locks cannot provide indoor lighting. In order to provide users with timely and accurate lighting when they enter the door, an embodiment of the present application provides a smart door lock, which includes a rotating mechanism and a camera, and a lamp body is fixed around the camera.

[0075] The lamp body and the camera can be arranged on an external door lock outside the door, and the lamp body can be used for lighting outside the door.

[0076] The lamp body and the camera can be set in the inner door lock inside the door. In this case, the lamp body can be used for lighting inside the house. The lamp body can also be used as a warning. For example, when there is a thief, the light flashes to warn.

[0077] The lamp body and the camera are both installed on the rotating mechanism so that the lamp body rotates together with the camera.

[0078] The following functions can be set: the camera rotates to follow the movement of the person, and the light of the lamp body follows the movement of the person. One way is to keep the camera always on, analyze the captured image to obtain the person's location information, and rotate based on the person's location information. Another way is to configure a radar module to track the person's location.

[0079] The following function may be further provided: the camera rotates following the movement of the person, and the light of the lamp body is focused on the space in front of the person, so that the person can be provided with lighting more accurately.

[0080] like Figure 2 The lamp body 5 can be symmetrically distributed on the periphery of the camera 6. The lamp body 5 and the camera 6 are installed on a rotating mechanism 7. The rotating direction of the rotating mechanism 7 can be left and right to track a person moving in the horizontal direction. When the rotating mechanism 7 rotates, the lamp body 5 and the camera 6 are driven to rotate together.

[0081] like Figure 2 The inner door lock may also be provided with a display screen 8, a light sensor 9, a radar module 10 and other components 11. The other components 11 may include buttons, batteries, etc. When a battery is installed in the inner door lock, the battery can power the lamp body 5, and the lamp body 5 can be used for emergency lighting in the house when the mains power is off.

[0082] The smart door lock may also include a radar module 10 and a controller. The controller may be a lock control MCU, that is, a microprocessor specifically used to control the smart lock. The lock control MCU integrates multiple functions, such as touch control, RFID smart card detection, etc., reducing the need for external chips.

[0083] The radar module 10 may include a 24GHz radar with a measurement distance range of 5 to 20m, which can be used for indoor human body detection. Compared with the PIR sensor, the 24GHz radar can accurately measure the distance and azimuth angle of the target object. After being processed by the MCU algorithm, it can detect the stillness, movement, distance and angle of the object, and can detect whether there is a person in the appropriate distance area, whether it is active or stationary.

[0084] The radar module 10, the controller and the camera can be configured with the following control logic:

[0085] The radar module 10 is used to send a first signal to the controller when detecting an active target in a set space; the first signal may be an interrupt signal used to wake up the controller;

[0086] The controller is used to send a second signal to the camera 6 after receiving the first signal; the second signal is used to activate the human state determination function of the camera 6;

[0087] The camera 6 is used to judge the humanoid state after receiving the second signal and send the humanoid state parameters to the controller; before receiving the second signal, the camera 6 can be in a standby state and does not judge the humanoid state, thereby saving power consumption;

[0088] The controller is also used to send a request angle signal to the radar module 10 when the humanoid state parameter is true;

[0089] The radar module 10 is also used to detect the azimuth angle of the human figure after receiving the request angle signal, and send the azimuth angle of the human figure to the controller;

[0090] The controller is also used to control the rotation of the rotating mechanism 7 according to the orientation angle of the human figure.

[0091] According to the above control logic, the camera and the lamp body can track the movement of people. On the basis of tracking the movement of people, the camera can be further configured with a face recognition function. The camera 6 can be used to perform face recognition on the human figure when the human figure state parameter is true, and determine whether the human figure is a legal registered user. When the human figure is a legal registered user, no action such as an alarm is required. When the human figure is identified as an illegal registered user, the camera can use sound and light to issue an alarm, and can also remotely send information about illegal intrusion to the user's user control terminal (for example, a mobile phone as a user control terminal, through an app), and can also take pictures of the human figure, store photos or videos, etc. The options provided by the user control terminal to the user include adding this unregistered user as a legal user or calling the police.

[0092] In the case where the humanoid state parameter is false, the controller can be used to turn off the power of the camera 6 or put the camera 6 into a standby state, and at the same time, the controller can put the radar module 10 into a standby state; the standby state of the camera 6 means that face recognition is not performed; the standby state of the radar module 10 means that humanoid activity detection is continuously performed, and distance detection and angle detection are not performed. At this time, the rotating mechanism 7 does not need to rotate, which further saves power consumption.

[0093] For the control of the lamp, the ambient light intensity can be detected by the light sensor 9, and the switch or brightness of the lamp can be controlled according to the detection of the light sensor 9, thereby saving power consumption. Figure 3 , Figure 3 An embodiment in which the radar module 10, the controller 12, the light sensor 9 and the camera 6 are interconnected is shown.

[0094] For the control of the lamp, you can also combine the distance of the human figure to control the switch or brightness of the lamp. The control logic is as follows:

[0095] The controller is also used to send a request distance signal to the radar module 10 when the humanoid state parameter is true;

[0096] The radar module 10 is also used to detect the distance of the human figure after receiving the request distance signal, and send the distance of the human figure to the controller;

[0097] The controller is also used to control the brightness of the lamp body 5 according to the distance of the human figure and the light intensity detected by the light sensor 9.

[0098] The sensing range of the light sensor can be 0Lux~100Lux, where Lux is the unit of illumination. The signal generated by the light sensor sensing the indoor ambient light can be converted into high and low levels according to the light intensity threshold through the operational amplifier circuit and output to the radar module. For example, when 10Lux is used as the light intensity threshold, the ambient light illumination of 0Lux~10Lux corresponds to a high level; the ambient light illumination of 10Lux~100Lux corresponds to a low level.

[0099] The radar module 10 is used to send a low-light signal to the controller when the light sensor level indicates that the light intensity is less than the light intensity threshold. When the controller receives the low-light signal, it controls the lamp to work according to the distance of the human figure.

[0100] The lamp body 5 includes a plurality of partition lamps with different irradiation directions, and the partition lamps are divided into two parts along the left and right directions, such as Figure 4, the lamp body 5 may include a first-zone lamp 51, a second-zone lamp 52, and a third-zone lamp 53, which are powered by the controller 12. The first-zone lamp 51 can irradiate to the left, the second-zone lamp 52 can irradiate towards the middle, and the third-zone lamp 53 can irradiate to the right. Then, the controller can control the brightness of each partition lamp according to the azimuth angle, distance, and light intensity of the human figure, and can adjust the irradiation direction of the lamp body. The controller 12 also has a GPIO_Motor port for controlling the rotating mechanism. While controlling the rotation, it controls the operation of different partition lamps, which can expand the adjustment range of the direction and make the response of the direction adjustment faster.

[0101] The controller can control the partition lighting system by obtaining the angle and distance parameters of the radar module. The controller controls the lamp of one partition according to the obtained radar module angle, and then controls the on / off of the lamp in this partition according to the light intensity. Figure 5 A way of angle division is shown. The angle control on / off logic is as follows: control the on / off of the third-zone lamp in the area from 60° to 30°, control the on / off of the second-zone lamp from 330° to 30°, and control the on / off of the first-zone lamp from 300° to 330°. When the light sensor 9 detects that the ambient light intensity is less than the light intensity threshold, control the lamp in this area to turn on. When the light sensor 9 detects that the ambient light intensity is greater than the light intensity threshold, control the lamp in this area to turn off.

[0102] When the light sensor 9 detects that the ambient light intensity is less than the light intensity threshold, the brightness can be further controlled. Figure 6 A schematic diagram of distance control of brightness and darkness is shown. The logic of distance control of brightness and darkness is that when the distance is farther, the brightness of the corresponding partition lamp is greater, and when the distance is closer, the brightness of the corresponding partition lamp is smaller.

[0103] The angle of radar ranging is denoted as A (angle), the distance is denoted as D (distance), 0 ≤ D ≤ 20, the brightness and darkness of the lamp group is denoted as L (light) and PWM dimming is used; the on / off of the lamp group is denoted as O (On / Off); the PWM parameter is α, and the PWM parameter can be a preset fixed value, 0 < α < 1; the brightness coefficient is β, and the brightness coefficient can be a preset fixed value. The brightness formulas of different partition lamps can be expressed as follows:

[0104] Brightness of the first-zone lamp:

[0105] L1_PWM = D * (1 - α) * β * O1

[0106] On / off of the first-zone lamp:

[0107] O1 = A1 (true when 300° < A1 < 330°, O1 value is 1; false otherwise, O1 value is 0)

[0108] Brightness of the second-zone lamp:

[0109] L2_PWM = D * (1 - α) * β * O2

[0110] On - off state of the second - zone lamp:

[0111] O2 = A2 (When 30° < A2 < 330° is true, the value of O2 is 1; otherwise, the value of O2 is 0)

[0112] Brightness of the third - zone lamp:

[0113] L3_PWM = D * (1 - α) * β * O3

[0114] On - off state of the third - zone lamp:

[0115] O3 = A3 (When 30° < A3 < 60° is true, the value of O3 is 1; otherwise, the value of O3 is 0)

[0116] According to the above formulas, the partition lamps corresponding to the set angle range work. The farther the distance is, the greater the brightness is.

[0117] The controller can also be configured to determine the space in front of a person through the radar module 10 or the camera 6, and control the brightness of each partition lamp to be concentrated in the space in front of the person. For example, when the controller detects that a person moves from left to right, it controls the partition lamp on the left - hand side to become dimmer and the partition lamp on the right - hand side to become brighter; when it detects that a person moves from right to left, it controls the partition lamp on the right - hand side to become dimmer and the partition lamp on the left - hand side to become brighter. Concentrating the light on the space in front of the person rather than on the person himself can make it more convenient for the user to use, and can also avoid the situation where the light lags behind when the person is moving forward.

[0118] The device and system embodiments described above are merely illustrative. Some or all of the modules can be selected according to actual needs to achieve the purpose of the solution of this embodiment. A person of ordinary skill in the art can understand and implement it without creative work.

[0119] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any change or replacement that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
