[0036] As described above, current smart door locks usually rely on batteries for power supply, and the existing video acquisition methods used in smart door locks consume too much power. Long-term high power consumption operation will quickly deplete the battery power of the smart door lock, causing the smart door lock to fail to work properly, causing inconvenience to users.
[0037] After research, the inventor proposed a video acquisition control method and related products applied to smart door locks.
[0038] First, in response to detecting a first detection signal and a second detection signal, a first detection result is generated based on the first detection signal and the second detection signal; the first detection signal comes from a built-in sensor of the camera of the smart door lock; the second detection signal comes from an infrared sensor; when the first detection result indicates that the target object is not detected, the camera is controlled to perform video acquisition in a low-power working mode; in the low-power working mode, the clock source of the camera is an external clock source; when the first detection result indicates that the target object is detected, the camera is controlled to perform video acquisition in a normal working mode; in the normal working mode, the clock source of the camera is the processor of the smart door lock; the frequency of the clock signal generated by the external clock source is lower than the frequency of the clock signal generated by the processor of the smart door lock.
[0039] In order to enable those skilled in the art to better understand the solution of the present application, 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. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0040] See also Figure 1 , which is a flow chart of a video acquisition control method applied to a smart door lock provided by an embodiment of the present application, such as Figure 1 As shown, the video acquisition control method applied to the smart door lock provided in the embodiment of the present application includes:
[0041] S101 . In response to detecting a first detection signal and a second detection signal, generate a first detection result based on the first detection signal and the second detection signal.
[0042] In an embodiment of the present application, an infrared sensor is included in the smart door lock, and a camera of the smart door lock has a built-in sensor for detecting whether a target object appears within the monitoring range of the camera of the smart door lock.
[0043] In an example implementation, the sensor built into the camera of the smart door lock is a sensor with built-in motion detection function, which can analyze and compare the brightness changes between two adjacent frames of images collected by the camera during video acquisition to determine whether a target object appears. If the brightness change between two adjacent frames of images reaches a preset threshold, the sensor determines that the target object is detected.
[0044] In the embodiment of the present application, the smart door lock also includes an infrared sensor
[0045] In an exemplary implementation, the infrared sensor in the smart door lock may be a passive infrared sensor (PIR). The PIR sensor can capture changes in infrared radiation in the environment, especially infrared radiation emitted by warm-blooded animals such as the human body.
[0046] When the target object enters the monitoring range of the PIR sensor, the temperature difference between the target object and the surrounding environment will cause the infrared radiation field to change, and the pyroelectric element in the PIR sensor will produce a weak electrical signal change. This electrical signal is then amplified and analyzed by the signal processor in the PIR sensor. Once the change exceeds the preset threshold, the PIR sensor determines that the target object has been detected.
[0047] In response to detecting the first detection signal and the second detection signal, the embodiment of the present application generates a first detection result based on the first detection signal and the second detection signal. The first detection result is used to indicate whether the target object is detected.
[0048] In an embodiment of the present application, the first detection signal comes from the built-in sensor of the camera of the smart door lock, indicating whether the built-in sensor of the camera detects changes in the picture; the second detection signal comes from the infrared sensor.
[0049] In an embodiment of the present application, when the first detection signal indicates that a picture change is detected and the second detection signal indicates that an infrared change is detected, the generated first detection result indicates that the target object is detected; when the first detection signal indicates that a picture change is detected, but the second detection signal indicates that an infrared change is not detected, the generated first detection result indicates that the target object is not detected; when the first detection signal indicates that no picture change is detected, but the second detection signal indicates that an infrared change is detected, the generated first detection result indicates that the target object is not detected; when the first detection signal indicates that no picture change is detected, but the second detection signal indicates that an infrared change is detected, the generated first detection result indicates that the target object is not detected; when the first detection signal indicates that no picture change is detected, and the second detection signal indicates that no infrared change is detected, the generated first detection result indicates that the target object is not detected.
[0050] S102: Determine whether the first detection result indicates that a target object is detected.
[0051] In the embodiment of the present application, the first detection result generated in the determination step S101 indicates whether the target object is detected.
[0052] When the first detection result indicates that the target object is not detected, the process proceeds to step S103 ; when the first detection result indicates that the target object is detected, the process proceeds to step S104 .
[0053] S103: Control the camera to perform video acquisition in a low power consumption working mode.
[0054] In an embodiment of the present application, the working mode of the camera includes a low power working mode and a normal working mode to adapt to different monitoring needs.
[0055] In low-power working mode, the camera needs a stable, low-power clock source to maintain its basic operation. At this time, the clock source of the camera is an external clock source.
[0056] In an exemplary implementation, the external clock source may be a low power crystal oscillator or similar component with an operating current of less than 1 mA.
[0057] S104: Control the camera to collect video in a normal working mode.
[0058] In an embodiment of the present application, the smart door lock also includes a processor. In normal working mode, the clock source of the camera is the processor of the smart door lock.
[0059] In an embodiment of the present application, the frequency of the clock signal generated by the external clock source is lower than the frequency of the clock signal generated by the processor of the smart door lock.
[0060] The embodiment of the present application combines the first detection signal generated by the camera of the smart door lock and the second detection signal generated by the infrared sensor to jointly determine whether the target object is detected, thereby avoiding misjudgment of a single sensor. When the target object is not detected, the camera is controlled to perform video capture in a low-power working mode that only requires a low-frequency clock signal. The power consumption of the smart door lock when performing video capture tasks is reduced, thereby greatly improving the overall user experience without affecting the monitoring effect and safety.
[0061] Optionally, when the camera is in the low power consumption working mode, the video is recorded at a first frame rate; when the camera is in the normal working mode, the video is recorded at a second frame rate, wherein the first frame rate is lower than the second frame rate.
[0062] Optionally, when the camera is in the low power consumption working mode, the video is recorded at a first resolution; when the camera is in the normal working mode, the video is recorded at a second resolution, wherein the first resolution is smaller than the second resolution.
[0063] In an example implementation, when the camera is in low power mode, it records video at 1 frame / s and 320×240 resolution; when the camera is in normal mode, it records video at 30 frames / s and 1920×1080 resolution.
[0064] Optionally, in order to further reduce the occurrence of misjudgment, the video acquisition control method applied to the smart door lock also includes:
[0065] Step 1: In response to detecting the third detection signal, generate a second detection result based on the first detection signal, the second detection signal and the third detection signal.
[0066] In an embodiment of the present application, the smart door lock includes a radar sensor, and the third detection signal comes from the radar sensor.
[0067] Radar sensors detect the presence and movement of objects by emitting electromagnetic waves and receiving the signals reflected back. It uses wireless detection technologies such as Frequency Modulated Continuous Wave (FMCW) to detect movement by calculating the shape, position, movement trajectory and movement characteristics of the object.
[0068] In the embodiment of the present application, the third detection signal is used to indicate that the radar sensor detects a motion signal.
[0069] In the embodiment of the present application, the first detection signal generated by the built-in sensor of the camera of the smart door lock, the second detection signal generated by the infrared sensor and the third detection signal generated by the radar sensor together generate a second detection result. The second detection result indicates whether the target object is detected.
[0070] In an embodiment of the present application, when the first detection signal indicates that a picture change is detected, the second detection signal indicates that an infrared change is detected, and the third detection signal indicates that a motion signal is detected, the generated second detection result indicates that the target object and the motion signal are detected; in other cases, the generated second detection result indicates that the target object and the motion object are not detected.
[0071] Step 2: When the second detection result indicates that the target object and the motion signal are not detected, the camera is controlled to perform video acquisition in a low power consumption working mode.
[0072] In low-power working mode, the camera needs a stable, low-power clock source to maintain its basic operation. At this time, the clock source of the camera is an external clock source.
[0073] Step 3: When the second detection result indicates that the target object and the motion signal are detected, the camera is controlled to perform video acquisition in a normal working mode.
[0074] In normal working mode, the clock source of the camera is the processor of the smart door lock.
[0075] Step 4: When the second detection result indicates that the duration for which no moving object and no moving signal are detected reaches a preset duration, the working mode of the camera is switched to a low power consumption working mode.
[0076] In the video acquisition control process of the smart door lock, in order to further optimize the balance between energy consumption and security monitoring, it is unnecessary to continue to maintain the normal working mode of the camera when no target object or motion signal is detected for a long time.
[0077] Therefore, in an embodiment of the present application, when the second detection result indicates that the time duration for which the target object and mobile signal are not detected reaches a preset time duration (such as 5 minutes, 10 minutes, etc., and the specific time duration can be set according to actual needs and security levels), the camera's working mode is switched to a low power working mode.
[0078] Step 5: Store the video information collected when the camera is in normal working mode.
[0079] In the embodiment of the present application, although the camera reduces energy consumption in the low-power working mode, in order to ensure that necessary evidence can be provided when a potential security incident occurs, the system needs to properly store the video information collected when the camera is in the normal working mode.
[0080] Therefore, in an embodiment of the present application, while the camera is in normal working mode, all collected video information will be transmitted in real time to the storage device inside the smart door lock (such as a built-in SD card, cloud storage, etc.).
[0081] The storage device has sufficient capacity to store video information for a certain period of time to ensure that it can be retrieved and reviewed when needed.
[0082] The stable supply of clock source is an important guarantee for the operation of the camera. In order to ensure that the camera can obtain the most suitable clock source in different working modes, the video acquisition control method applied to the smart door lock may also include:
[0083] Since the normal operating mode requires a higher frame rate and resolution to capture video information, the camera needs a more stable and accurate clock signal to support its operation.
[0084] In an embodiment of the present application, when the camera switches from a low-power working mode to a normal working mode, the clock source controlling the camera is switched from an external clock source to a processor of the smart door lock.
[0085] When the camera needs to switch from normal working mode to low power working mode, in order to reduce energy consumption and extend the service life of the smart door lock, the system needs to ensure that the camera can switch to a low power clock source.
[0086] In an embodiment of the present application, when the camera switches from a normal operating mode to a low power operating mode, the clock source controlling the camera is switched from the processor of the smart door lock to an external clock source.
[0087] The embodiment of the present application realizes accurate judgment of target objects and mobile signals by combining multiple sensor signals (including the image change detection signal of the camera's built-in sensor, the infrared change detection signal of the infrared sensor, and the optional motion signal detection of the radar sensor), effectively avoiding the misjudgment that may occur in a single sensor, thereby improving the accuracy and reliability of the monitoring system. At the same time, the working mode of the camera is dynamically adjusted according to the detection results, thereby achieving a significant reduction in the video acquisition power consumption of the smart door lock while ensuring the monitoring effect and safety, thereby improving the user experience.
[0088] Based on the video acquisition control method applied to the smart door lock provided in the aforementioned embodiment, the present application also provides a video acquisition control device applied to the smart door lock. Figure 2 The structure diagram of a video acquisition control device applied to a smart door lock provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the video acquisition control device applied to the smart door lock includes: a first detection result generating module 201, a first control module 202 and a second control module 203.
[0089] The first detection result generating module 201 is configured to generate a first detection result based on the first detection signal and the second detection signal in response to detecting the first detection signal and the second detection signal.
[0090] In the embodiment of the present application, the first detection signal comes from a built-in sensor of a camera of the smart door lock, and the second detection signal comes from an infrared sensor.
[0091] In an example implementation, the sensor built into the camera of the smart door lock is a sensor with built-in motion detection function, which can analyze and compare the brightness changes between two adjacent frames of images collected by the camera during video acquisition to determine whether a target object appears. If the brightness change between two adjacent frames of images reaches a preset threshold, the sensor determines that the target object is detected.
[0092] In an exemplary implementation, the infrared sensor in the smart door lock may be a passive infrared sensor (PIR). The PIR sensor can capture changes in infrared radiation in the environment, especially infrared radiation emitted by warm-blooded animals such as the human body.
[0093] When the target object enters the monitoring range of the PIR sensor, the temperature difference between the target object and the surrounding environment will cause the infrared radiation field to change, and the pyroelectric element in the PIR sensor will produce a weak electrical signal change. This electrical signal is then amplified and analyzed by the signal processor in the PIR sensor. Once the change exceeds the preset threshold, the PIR sensor determines that the target object has been detected.
[0094] In the embodiment of the present application, when the first detection signal indicates that a picture change is detected and the second detection signal indicates that an infrared change is detected, the first detection result generated by the first detection result generating module 201 indicates that a target object is detected; when the first detection signal indicates that a picture change is detected, but the second detection signal indicates that an infrared change is not detected, the first detection result generated by the first detection result generating module 201 indicates that the target object is not detected; when the first detection signal indicates that no picture change is detected, but the second detection signal indicates that an infrared change is detected, the first detection result generated by the first detection result generating module 201 indicates that the target object is not detected; when the first detection signal indicates that no picture change is detected, but the second detection signal indicates that an infrared change is detected, the first detection result generated by the first detection result generating module 201 indicates that the target object is not detected; when the first detection signal indicates that no picture change is detected, and the second detection signal indicates that no infrared change is detected, the first detection result generated by the first detection result generating module 201 indicates that the target object is not detected.
[0095] The first control module 202 is configured to control the camera to perform video acquisition in a low power consumption working mode when the first detection result generated by the first detection result generating module 201 indicates that the target object is not detected.
[0096] In low power mode, the camera's clock source is an external clock source.
[0097] The second control module 203 is configured to control the camera to perform video acquisition in a normal working mode when the first detection result generated by the first detection result generating module 201 indicates that the target object is detected.
[0098] In normal working mode, the clock source of the camera is the processor of the smart door lock.
[0099] In an embodiment of the present application, the frequency of the clock signal generated by the external clock source is lower than the frequency of the clock signal generated by the processor of the smart door lock.
[0100] The embodiment of the present application combines the functions of the first detection result generation module 201, the first control module 202 and the second control module 203 to achieve a significant improvement in the overall user experience without affecting the monitoring effect and safety.
[0101] In an optional implementation, when the first control module 202 controls the camera to operate in a low power consumption mode, the video is recorded at a first frame rate; when the second control module 203 controls the camera to operate in a normal working mode, the video is recorded at a second frame rate, wherein the first frame rate is lower than the second frame rate.
[0102] In an optional implementation, when the first control module 202 controls the camera to operate in a low power consumption mode, the video is recorded at a first resolution; when the second control module 203 controls the camera to operate in a normal working mode, the video is recorded at a second resolution, wherein the first resolution is smaller than the second resolution.
[0103] In an optional implementation, the video acquisition control device applied to the smart door lock further includes:
[0104] The second detection result generating module is configured to generate a second detection result based on the first detection signal, the second detection signal and the third detection signal in response to detecting the third detection signal.
[0105] The third detection signal comes from the radar sensor and is used to indicate that the radar sensor detects a motion signal.
[0106] When the first detection signal indicates that a picture change is detected, the second detection signal indicates that an infrared change is detected, and the third detection signal indicates that a motion signal is detected, the second detection result generated by the second detection result generating module indicates that a target object and a motion signal are detected.
[0107] In other cases, the second detection result generated by the second detection result generating module indicates that the target object and the moving object are not detected.
[0108] The third control module is used to control the camera to perform video acquisition in a low power consumption working mode to reduce power consumption when the second detection result indicates that the target object and the motion signal are not detected.
[0109] The fourth control module is used to control the camera to perform video acquisition in a normal working mode to perform high-quality video acquisition when the second detection result indicates that the target object and the motion signal are detected.
[0110] In an optional implementation, the video acquisition control device applied to the smart door lock further includes:
[0111] The working mode switching module is used to switch the working mode of the camera to a low power consumption working mode when the second detection result generated by the second detection result generating module indicates that the duration for which no moving object and no moving signal are detected reaches a preset duration.
[0112] In an embodiment of the present application, the preset duration may be 5 minutes or 10 minutes, etc. The specific duration may be set according to actual needs and security level.
[0113] The storage module is used to store the video information collected when the camera is in normal working mode.
[0114] In an embodiment of the present application, the received video information is stored in a storage device inside the smart door lock (such as an SD card, a built-in hard disk, or a cloud storage service) for subsequent viewing and analysis.
[0115] In an optional implementation, the video acquisition control device applied to the smart door lock further includes:
[0116] The first clock source switching module is used to control the clock source of the camera to switch from an external clock source to the processor of the smart door lock when the camera switches from a low-power working mode to a normal working mode, so as to ensure that the camera can work normally.
[0117] The second clock source switching module is used to control the clock source of the camera to switch from the processor of the smart door lock to the external clock source when the camera switches from the normal working mode to the low power consumption working mode, so as to reduce the overall power consumption.
[0118] In the embodiment of the present application, after the video acquisition control device applied to the smart door lock is started, the first detection result generation module 201 starts to obtain and process the detection signal from the camera built-in sensor and the infrared sensor to generate the first detection result. According to the first detection result, the first control module 202 or the second control module 203 controls the camera to enter the low power working mode or the normal working mode respectively.
[0119] Optionally, if the video acquisition control device applied to the smart door lock includes a second detection result generation module, the third detection signal from the radar sensor is received and processed at the same time to generate a second detection result. According to the second detection result, the third control module or the fourth control module further adjusts the working mode of the camera. When the camera is in a normal working mode, the storage module receives and stores the video information collected by the camera. When the camera working mode is switched, the first clock source switching module or the second clock source switching module automatically adjusts the clock source of the camera.
[0120] The embodiment of the present application realizes the intelligent management of the camera working mode, thereby greatly reducing the video acquisition power consumption of the smart door lock while ensuring the monitoring effect and safety, and improving the overall user experience.
