the video input unit 201 can be used for receiving the video signal and controlling the screen display unit 202 to display video.
Specifically, the entity detector 102 may periodically detect whether an entity is near the door, in practical applications, most entities are human bodies, and the specific detection method may include, but is not limited to, infrared, laser, and the like.
After the presence of the entity is determined, the acquisition of the image may be started, so that the entity detector 102 may send an instruction to the micro control unit 103. The micro control Unit may include an MCU, and specifically, the Micro Control Unit (MCU), also called a Single Chip Microcomputer (Single Chip Microcomputer) or a Single Chip Microcomputer, may appropriately reduce the frequency and specification of a Central Processing Unit (CPU), and integrate peripheral interfaces such as a memory, a counter, a USB (Universal Serial Bus), a UART (Universal Asynchronous Receiver/Transmitter), and the like on a Single Chip to form a Chip-level computer, so as to perform different combination control for different application occasions. And in the utility model discloses in, little the control unit 103 in the lock main part, can be used for realizing the function in the lock main part.
When the micro control unit 103 receives the instruction from the physical detector 102, it can control the image sensor 101 to capture the image outside the door.
Further, the image sensor 101 may capture an image outside the door, specifically, may convert the captured optical signal into an electrical signal to obtain image data, and may transmit the image data to the video output unit 1041 in the image processing chip 104 in order to display the image on the display screen.
The image processing Chip may include an SOC (System on Chip), which may also be referred to as a System on Chip, and may refer to a product, an integrated circuit with a dedicated target, which may contain a complete System and have embedded software.
The video output unit 1041, upon receiving the image data, may then output the video signal to the video input unit 201 in the display screen 20 in a predetermined signal type. Specifically, the signal type may include an analog video signal, a digital video signal, and the like.
The video input unit 201 as an input end can receive the video signal and control the screen display unit 202 to perform video display on the received video signal.
In practical application, the door lock independent power supply 105 may be integrated in the door lock main body 10 to supply power to each component integrated in the door lock main body 10; the display screen independent power source 203 may be integrated in the display screen 20 to supply power to the components integrated in the display screen 20. In practical application, the two power sources may be batteries, and the user may supply power through dry batteries or rechargeable lithium batteries.
As already mentioned above, the entity detector 102 may periodically detect and in practice, entities may be present outdoors, usually as haphazard events during the day, and most households will not have all their persons present for the majority of the time. Therefore, power supply for a long time is not required for the image sensor 101 and the image processing chip 104 in the door lock main body. In one embodiment, in order to save power, a power control unit may be integrated into the door lock main body 10, as shown in fig. 2, which is another structural diagram of the door lock main body.
Specifically, the door lock independent power supply 105 can always supply power to the entity detector 102 and the control unit 103, while for the image sensor 101 and the image processing chip 104, power supply does not need to be maintained, and after the entity detector 102 detects that an entity appears outside the door and sends an instruction to the micro control unit 103, the micro control unit 103 at this time can control the door lock independent power supply 105 to start power supply for the image sensor 101 and the image processing chip 104 through the power supply control unit 106 according to the instruction.

That is, when the door lock main body detects that there is a person outside the door, the micro control unit 103 controls the door lock independent power supply 105 to supply power to the image processing chip 104 through the power supply control unit 106, so that the image processing chip 104 is powered on to operate.
In practical applications, people outside the door generally do not stay for a long time, and thus it is not necessary to acquire images all the time, for example, in general, the time duration of standing outdoors is kept about 10 seconds. Therefore, in one embodiment, in order to save power, the mcu 103 may further control the power control unit 106 to turn on power supply for the image sensor 101 and the image processing chip 104 for a preset time according to the instruction.
Specifically, as shown in fig. 2, after the power supply control unit 106 controls the door lock independent power supply 105 to supply power to the image processing chip 104, an operation countdown may be set, which may be generally within 10 to 30 seconds, and the user may set the operation countdown according to his/her needs, for example, 10 seconds, 20 seconds, or even 1 minute. After the countdown is finished, the micro control unit 103 may control the door lock independent power supply 105 to power off the image processing chip 104, thereby saving power as much as possible.
In practical applications, some image processing may be performed after the image sensor 101 acquires image data in order to obtain a clearer image. Therefore, in one embodiment, the image processing chip 104 may further integrate an image processing unit therein, as shown in fig. 3, which is another structural diagram of the door lock body. An image processing unit 1042 is also included.
The image sensor 101 may acquire an image outside the door and transmit the acquired image data to the image processing unit 1042;
the image processing unit 1042 may receive and pre-process the image data, and transmit the pre-processed image data to the video output unit 1041;
the video output unit 1041 may receive the preprocessed image data and output a video signal to the video input unit 201 in a predetermined signal type.
Specifically, the image sensor 101 may collect an image outside the door, and convert the collected optical signal into an electrical signal according to the foregoing, so as to obtain image data, which may be transmitted to the image processing unit 1042 as raw data. Thereafter, the image processing unit 1042 may perform pre-processing on the original image data, specifically, but not limited to, pre-processing operations including image noise reduction, wide dynamic range, etc., in order to make the image clearer.
After the pre-processing, the pre-processed image data may be transmitted to the video output unit 1041, so that the video output unit 1041 outputs the video signal to the video input unit 201 in a predetermined signal type.
In practical applications, in order to display video sizes meeting different requirements, a video encoding unit may be integrated into the image processing chip 104, as shown in fig. 4, which is another structural diagram of the door lock main body. A video encoding unit 1043 is also included.
The image sensor 101 may acquire an image outside the door and transmit the acquired image data to the video encoding unit 1043;
the video encoding unit 1043 may receive the image data, perform encoding and/or compression processing, and transmit the processed image data to the video output unit 1041;
the video output unit 1041 may receive the processed image data and output a video signal to the video input unit 201 in a predetermined signal type.
Specifically, the image sensor 101 may capture an image of the outside of the door, convert the captured light signal into an electrical signal according to the foregoing description to obtain image data, and transmit the image data to the video encoding unit 1043. Thereafter, the video encoding unit 1043 may perform encoding and/or compression processing on the image data, specifically, for example, video encoding may be performed in a specific format, data size compression may be performed at a predetermined compression ratio, and the like, so as to obtain a video size meeting the requirement.
Of course, the image processing unit 1042 and the video encoding unit 1043 described above may be integrated into the image processing chip 104, that is, as shown in fig. 4, the image sensor 101 transmits the acquired image data as raw data to the image processing unit 1042, performs image preprocessing such as noise reduction and wide dynamic range, transmits the preprocessed image data to the video encoding unit 1043, performs processing such as video encoding and data amount compression, transmits the processed image data to the video output unit 1041, and finally, the video output unit 1041 outputs a video signal to the video input unit 201 in a predetermined signal type.
In practical applications, users may have different requirements for the displayed video for different reasons, such as a need for a larger or smaller display size, a need for different shades, and for example, a relatively dark outdoor corridor may have a higher definition requirement, while a relatively bright outdoor corridor may have a lower definition requirement for power saving purposes. Therefore, in one embodiment, in order to satisfy different video requirements, the mcu 103 may send a video requirement to the image processing chip 104, so that the image processing chip 104 can output a video signal satisfying the video requirement.
Specifically, as described above, the image sensor 101 may transmit the acquired image data as raw data to the image processing unit 1042, perform image preprocessing such as noise reduction and wide dynamic range, transmit the preprocessed image data to the video encoding unit 1043, perform processing such as video encoding and data size compression, perform encoding and compression with reference to the requirements of size, brightness, resolution, and ratio in the video requirement when performing video encoding and data size compression, and then transmit the image data meeting the definition requirement to the video output unit 1041.
In practical applications, the mcu 103 and the image processing chip 104 can perform command interaction based on the UART described above.
As described above, the video output unit 1041 can output a video signal in a predetermined signal type when outputting the video signal. For example, in the form of a digital video signal, or an analog video signal. However, in the current implementation manner, based on the size of the display screen, the display effect, and the cost of the product, since the display screen and the door lock main body are in a separated state, it is necessary to implement remote transmission of video, and then the analog signal is an optional technical solution.
Therefore, in one embodiment, the video output unit 1041 may be configured to receive image data and output an analog video signal to the video input unit 201. Specifically, since a digital video signal is obtained based on the image sensor 101 and through the image processing unit 1042 and the video encoding unit 1043 in the image processing chip 104, the digital video signal can be converted by the video output unit 1041 and an analog video signal is output.
Correspondingly, a signal conversion unit 204 may be further integrated in the display screen 20, and the video input unit 201 may be configured to receive an analog video signal and transmit the analog video signal to the signal conversion unit 204;
a signal conversion unit 204, which can be used for receiving an analog video signal and converting the analog video signal into a digital video signal; the control screen display unit 202 displays video.
Specifically, as shown in fig. 5, it is a structural diagram of another display screen. When the video output unit 1041 receives the analog video signal, it can be used as a forwarding role to forward the analog video signal to the signal conversion unit 204, and the signal conversion unit 204 restores the analog video signal to a digital video signal again, and controls the screen display unit 202 to perform video display.
In practical applications, the analog Video Signal, which may include a CVBS, may be a Composite Video Broadcast Signal (Composite Video Broadcast Signal) or a Composite Video Blanking and synchronization (Composite Video Blanking and Sync), and is characterized by better support for long-distance transmission and lower cost. When the analog video signal is converted into the digital video signal, the digital video signal can be converted into the MIPI, the MIPI alliance can be a Mobile Industry Processor Interface (Mobile Industry Processor Interface) alliance, and the MIPI is an open standard and a specification which are initiated by the MIPI alliance and established for a Mobile application Processor.
Fig. 6 is a structural view of another intelligent door lock, which combines the door lock body and the display screen in fig. 4 and 5. Since most of the current image sensors 101 convert optical signals into digital signals and still perform digital processing after passing through the image processing unit 1042 and the video encoding unit 1043 in the image processing chip 104, in order to realize long-distance video output, the video output unit 1041 may convert image data into analog video signals and transmit the analog video signals to the video input unit 201, and since the current screen display unit is also mostly an interface of digital video signals (such as an RGB565 interface, etc.), the signal conversion unit 204 may be integrated in the display screen 20 to restore the analog video signals into digital video signals so as to drive the screen display unit to output video.
As already described above, to conserve power, the image processing chip 104 may be powered up after the entity detector 102 detects the presence of an entity. In the display panel 20, the video input unit 201 may also play a role of signal monitoring, so in an embodiment, in order to save power, the video input unit 201 may be configured to control the display panel independent power source 203 to turn on the power supply for the screen display unit 202 when it is monitored that a video signal is input.
In practical applications, if the display screen 20 is further integrated with the signal conversion unit 204, the display screen independent power source 203 can be controlled to supply power to the screen display unit 202 and the signal conversion unit 204 when video signals are monitored to be input.
Specifically, in practical applications, the display screen independent power source 203 may maintain to continuously supply power to the video input unit 201 with low power consumption, and when the video input unit 201 monitors that a video signal is sent by the video output unit 1041, the display screen independent power source 203 may be controlled to power on the screen display unit 202, or the screen display unit 202 and the signal conversion unit 204, so as to start working to implement video display.
In practical applications, in order to realize long-distance transmission, the video output unit 1041 and the video input unit 201 may transmit video data through a wire or wirelessly.
Specifically, the digital video signal may be transmitted through an HDMI (High Definition Multimedia Interface) wire, a DP (display Interface) wire, or the like, and the analog video signal may be transmitted through an RCA terminal (rcajack or RCA connector). Of course, the digital video signal may be transmitted wirelessly via wireless HDMI, Wi-Fi (wireless communication technology), or the like.
As shown in fig. 7, which is a schematic view of the intelligent door lock installed on a door, the view angle in the figure may be that inside the door, the door lock body 10 and the display screen 20 are separated, and based on a wired transmission video signal, then, a user may install display screens of different sizes according to the requirement, and may install the display screens at any position.
If the video signal is transmitted based on wireless, it can be understood that the user can install the display screen at any position in the home according to the user's needs.
As can be seen from the technical solutions provided in the above embodiments,
the utility model provides an among the intelligent door lock, with lock main part and display screen separation, under the independent condition separately, based on remote signal transmission, by the outdoor live image of image sensor collection in the lock main part to through the image processing chip, send video signal to the display screen, so that the display screen shows outdoor live, thereby realize in time, clearly learn outdoor live purpose.
