Abstract
Description
Technical Field
[0001] This application relates to the field of smart door lock technology. Background Technology
[0002] The interior lock of a smart door lock refers to the part of the smart door lock located inside the building. For example... Figure 1 The interior door lock is located inside the room. Typically, the mechanical components of the interior door lock include the door handle 2, the deadbolt knob 4, etc., while the electronic components include the visual peephole screen, the lithium battery compartment 1, the electronic locking button 3, etc.
[0003] When a user's room lacks an automatic sensor-activated lighting system, the user will not receive immediate illumination upon entering. Similarly, if a user leaves at night and turns off the room lights before leaving, they will still not receive illumination during that time.
[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, ordinary household appliances cannot provide indoor lighting when the mains power is cut off, including smart door locks currently on the market.
[0005] The technical problem this application aims to solve is how to provide users with timely and accurate lighting. Summary of the Invention
[0006] The purpose of this application is to provide a smart door lock that addresses the technical problem of providing users with timely and accurate lighting.
[0007] To achieve the above objectives, the embodiments of this application adopt the following technical solutions.
[0008] This application provides a smart door lock, including a rotating mechanism and a camera, with a light body fixed around the camera;
[0009] Both the lamp body and the camera are mounted 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 advantages:
[0011] The smart door lock provided in this application embodiment integrates 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 installed inside the door lock, and the lamp body is used for indoor lighting.
[0013] Optionally, the smart lock further includes a battery; the battery is used to power the lamp body.
[0014] The advantage of having a battery is that when a power outage occurs in the user's community at night or when the user's home circuit fails at night, the lamp can be used for emergency lighting in the house when the mains power is cut off.
[0015] Optionally, the camera rotates to follow the movement of the person, and the light from the lamp body also follows the movement of the person, which has the advantage of making the lighting provided by the smart door lock more precise.
[0016] Optionally, the camera is always on, and the captured images are analyzed to obtain the person's location information, and the camera rotates based on the person's location information.
[0017] Optionally, the smart lock may also include a radar module and a controller;
[0018] The radar module is used to send a first signal to the controller when it detects an active target in a designated space;
[0019] The controller is used to send a second signal to the camera after receiving the first signal;
[0020] The camera is used to determine the human form status after receiving the second signal and send the human form status parameters to the controller;
[0021] The controller is also configured to send a request angle signal to the radar module when the humanoid state parameter is true;
[0022] The radar module is also used to detect the orientation angle of the human figure after receiving the requested angle signal, and send the orientation angle of the human figure to the controller;
[0023] The controller is also used to control the rotation mechanism to rotate according to the orientation angle of the human figure.
[0024] The controller's rotating mechanism can rotate to align the camera and light source with the person, making it easier for the user to operate.
[0025] Optionally, the camera is used to determine the human form status and generate human form status parameters;
[0026] The camera is also used to perform facial recognition on the human figure when the human figure status parameter is true, and to determine whether the human figure is a legitimate registered user.
[0027] The beneficial effect of facial recognition technology in cameras is that it can detect unauthorized users and improve security. For example, it can promptly detect and alert when a thief passes through or exits a door.
[0028] Optionally, when the human figure is an unregistered user, the smart door lock sends an alarm message to the user control terminal (e.g., a mobile phone as the user control terminal, via an app). The options provided to the user by the user control terminal include adding this unregistered user as a legitimate user or triggering an alarm.
[0029] Optionally, when the humanoid state parameter is false, the power supply of the camera is turned off and the radar module enters standby mode;
[0030] The standby state refers to a state in which human activity is continuously detected, but distance and angle are not detected.
[0031] The radar module only needs to detect the orientation angle of the human figure when the human figure's state parameters are true. If the moving target is not a human, there is no need to continue detection, thereby saving power consumption.
[0032] Optionally, the smart lock also includes a light sensor, a radar module, and a controller;
[0033] The light sensor is used to detect ambient light intensity;
[0034] The camera is used to determine the human form status and send the human form status parameters to the controller;
[0035] The controller is also configured to send a distance request 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 humanoid figure after receiving the requested distance signal, and send the distance of the humanoid figure to the controller;
[0037] The controller is also used to control the brightness of the lamp body based on the distance of the human figure and the light intensity.
[0038] The brightness of the lamp can be flexibly controlled according to the ambient light intensity, avoiding excessive brightness or activating the lamp when the light intensity is sufficient, thus saving energy.
[0039] When the human figure is far away, the brightness of the lamp can be increased appropriately to make the light effective at a greater distance and easier for the user to use.
[0040] Optionally, the controller is used to rotate the camera to follow 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 multiple zone lamps with different illumination directions;
[0042] The controller is used to control the brightness of each zone light according to the orientation angle and distance of the human figure and the light intensity.
[0043] Zone lights can work in conjunction with a rotating mechanism to better adjust the beam angle and expand the range of beam angles.
[0044] Optionally, the controller is used to determine the space in front of a person through the radar module or the camera, and control the brightness of each of the zone lights to be concentrated in the space in front of the person.
[0045] Concentrating the light in the space in front of the person rather than on the person makes it more convenient for the user.
[0046] Optionally, the partition lights are divided into partitions along the left-right direction;
[0047] The controller is configured to dim the leftmost zone light and brighten the rightmost zone light when it detects that the person is moving from left to right; and to dim the rightmost zone light and brighten the leftmost zone light when it detects that the person is moving from right to left.
[0048] The left and right partitions can effectively adjust the direction of light output in the horizontal direction, and the structure is simple and easy to implement. Attached Figure Description

[0069] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described in the accompanying drawings can generally be arranged and designed in various different configurations.
[0070] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0071] In the description of this application, it should be noted that:
[0072] Relationship terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations;
[0073] "Connection" should be interpreted broadly. 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 also cannot provide indoor lighting. In order to provide timely and accurate lighting for users when they enter the door, this application provides a smart door lock, which includes a rotating mechanism and a camera, with a lamp body fixed around the camera.
[0075] The light fixture and camera can be installed on the outside of the door lock, in which case the light fixture can be used for lighting outside the door.
[0076] The light fixture and camera can be installed on the inner door lock. In this case, the light fixture can be used for indoor lighting, and it can also serve as a warning, such as flashing to alert the intruder.
[0077] Both the lamp body and the camera are mounted on a rotating mechanism so that the lamp body rotates together with the camera.
[0078] The following functions can be configured: the camera rotates to follow the person's movement, and the light from the lamp body also follows the person's movement. One method is to keep the camera constantly on, analyze the captured images to obtain the person's position information, and then rotate based on that position information. Another method is to configure a radar module to track the person's position.
[0079] The following functions can be further configured: the camera can rotate to follow the movement of the person and concentrate the light of the lamp body in the space in front of the person, so as to provide more accurate lighting for the person.
[0080] like Figure 2 The light body 5 can be symmetrically distributed around the camera 6. The light body 5 and the camera 6 are mounted on the rotating mechanism 7. The rotating mechanism 7 can rotate left and right to track people moving horizontally. When the rotating mechanism 7 rotates, it drives the light body 5 and the camera 6 to rotate together.
[0081] like Figure 2 The inner door lock can also be equipped with a display screen 8, a light sensor 9, a radar module 10, and other components 11. These other components 11 may include buttons, batteries, etc. When a battery is installed in the inner door lock, it can power the lamp body 5, allowing it to be used for emergency lighting inside the house in the event of a power outage.
[0082] The smart lock may also include a radar module 10 and a controller. The controller may be a lock control MCU, which is a microprocessor specifically designed to control the smart lock. The lock control MCU integrates multiple functions, such as touch control and RFID smart card detection, reducing the need for external chips.
[0083] Radar module 10 may include a 24GHz radar with a measurement range of 5 to 20m. It can be used for indoor human detection. Compared with PIR sensors, 24GHz radar can accurately measure the distance and azimuth angle of a target. After processing by MCU algorithms, it can detect whether an object is stationary, moving, or at a distance and angle. It can detect whether there is a person in a suitable distance area, and whether they are active or stationary.
[0084] The radar module 10, controller, and camera can be configured with the following control logic:
[0085] When a moving target is detected in a designated space, the radar module 10 sends a first signal to the controller; 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 judgment function of the camera 6.
[0087] Camera 6 is used to determine the human form status after receiving the second signal and send the human form status parameters to the controller; before receiving the second signal, camera 6 can be in standby mode and does not perform human form status determination to save power.
[0088] The controller is also used to send a request angle signal to the radar module 10 when the humanoid status parameter is true;
[0089] The radar module 10 is also used to detect the orientation angle of the human figure after receiving the requested angle signal, and send the orientation 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] Based on the aforementioned control logic, the camera and light fixture can track human movement. In addition to tracking movement, the camera can be further configured with facial recognition functionality. Camera 6 can perform facial recognition on a person when their status parameters are true, determining whether the person is a legitimate registered user. If the person is a legitimate registered user, no alarm or other actions are required. If the person is identified as an illegitimate registered user, the camera can issue an alarm using sound and light, and can also remotely send information about the unauthorized intrusion to the user's control terminal (e.g., a mobile phone as the control terminal via an app). It can also take photos, store images, or record videos of the person. The user control terminal provides options for the user, including adding the illegitimate user as a legitimate user or triggering an alarm.
[0092] When the human-like status parameters are false, the controller can shut down the power of camera 6 or put camera 6 into standby mode. Simultaneously, the controller can also put radar module 10 into standby mode. Standby mode for camera 6 means it does not perform face recognition; standby mode for radar module 10 means it continuously detects human activity but does not perform distance or angle detection. In this state, the rotating mechanism 7 also does not need to rotate, further saving power.
[0093] For lamp control, ambient light intensity can be detected by light sensor 9. Based on the detection by light sensor 9, the lamp's on / off state or brightness can be controlled, thereby saving power consumption. Figure 3 , Figure 3 One implementation is shown where the radar module 10, controller 12, light sensor 9 and camera 6 are interconnected.
[0094] The lamp can also be controlled by adjusting its on / off state or brightness based on the distance to the human figure. The control logic is as follows:
[0095] The controller is also used to send a distance request signal to the radar module 10 when the humanoid status parameter is true;
[0096] The radar module 10 is also used to detect the distance of the humanoid after receiving the requested distance signal, and send the distance of the humanoid to the controller;
[0097] The controller is also used to control the brightness of the lamp body 5 based on the distance of the human figure and the light intensity detected by the light sensor 9.
[0098] The light sensor's sensing range can be 0 Lux to 100 Lux, where Lux is a unit of illuminance. The signal generated by the light sensor sensing indoor ambient light can be passed through an operational amplifier circuit. The sensed light intensity is converted into high and low level outputs according to the light intensity threshold and then sent to the radar module. For example, when 10 Lux is used as the light intensity threshold, a high level corresponds to an ambient light intensity of 0 Lux to 10 Lux, and a low level corresponds to an ambient light intensity of 10 Lux to 100 Lux.
[0099] The radar module 10 is used to send an insufficient light signal to the controller when the light sensor level indicates that the illuminance is less than the light intensity threshold. Upon receiving the insufficient light signal, the controller controls the lamp to work based on the distance of the human figure.
[0100] The lamp body 5 includes multiple zone lamps with different illumination directions, and the zone lamps are arranged in a left-right direction, such as... Figure 4, the lamp body 5 can include a first - area lamp 51, a second - area lamp 52, and a third - area lamp 53, which are powered by the controller 12. The first - area lamp 51 can irradiate to the left, the second - area lamp 52 can irradiate towards the middle, and the third - area 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 logic of angle - controlled on - off is as follows: control the on - off of the third - area lamp in the area of 60° to 30°, control the on - off of the second - area lamp in the area of 330° to 30°, and control the on - off of the first - area lamp in the area of 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, it can further control the brightness. Figure 6 A schematic diagram of distance - controlled brightness and darkness is shown. The logic of distance - controlled 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 are 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 - area lamp:
[0105] L1_PWM = D*(1 - α)*β*O1
[0106] On - off of the first - area lamp:
[0107] O1 = A1 (true when 300° < A1 < 330°, O1 value is 1; false otherwise, O1 value is 0)
[0108] Brightness of the second - area lamp:
[0109] L2_PWM = D * (1 - α) * β * O2
[0110] On and off of the second - area lamp:
[0111] O2 = A2 (when 30° < A2 < 330° is true, the value of O2 is 1; otherwise it is false and the value of O2 is 0)
[0112] Brightness of the third - area lamp:
[0113] L3_PWM = D * (1 - α) * β * O3
[0114] On and off of the third - area lamp:
[0115] O3 = A3 (when 30° < A3 < 60° is true, the value of O3 is 1; otherwise it is false and 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 dim and the partition lamp on the right - hand side to brighten; when it detects that a person moves from right to left, it controls the partition lamp on the right - hand side to dim and the partition lamp on the left - hand side to brighten. 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. Those of ordinary skill in the art can understand and implement it without creative efforts. <
