Description

Technical Field

[0001] A low-power, high-definition, large-color-screen door lock is used in the field of smart door locks, especially in fields equipped with large-size color displays and requiring battery power. Background Art

[0002] With the continuous development of semiconductor technology, the door lock industry has also been evolving, from initial mechanical door locks to electronic door locks including card swipe and fingerprint, and then to fingerprint door locks, facial recognition door locks, finger vein door locks, and more. Door lock unlocking media are constantly upgrading, and various novel unlocking methods are constantly emerging. With the emergence of these new unlocking methods, the door lock industry faces the challenge of differentiated competition. Generally speaking, the higher the product, the higher the profit. To enhance the high-end attributes of the product, it is necessary to give it higher added value, which is why door locks with color screens have emerged.

[0003] At the time, because door locks were powered by lithium batteries, color screens could improve the quality of the door locks. However, the power consumption of the screen itself and the performance of the chip driving the door lock had a serious negative impact on the battery life of the door lock. To solve the problem of excessive power consumption of color screen door locks, ordinary household door locks generally use small color screens when using color screens, finding a balance between power consumption and functionality. Compared to small color screens, large color screens have higher power consumption due to their larger screens. Because of the larger screens, the resolution is also higher, and the performance requirements of the chip driving the screen are also higher. Therefore, the power consumption has always been a problem for door lock manufacturers. There are currently no lithium battery-powered high-definition large-screen smart door locks on the market.

[0004] To this end, the present invention provides a low-power, high-definition, large-color screen door lock, which is used to achieve ultra-low power consumption while providing both high-definition and large-color screen. Even when powered by batteries, the battery life can reach several months.

[0005] By using the present invention, at least the following effects can be achieved:

[0006] 1. Ultra-long battery life, using ordinary lithium batteries, can achieve several months of standby time.

[0007] 2. Ultra-delicate display effect, the screen can operate normally at a resolution of 1080P or above, achieving ultra-high-definition display effect.

[0008] 3. Ultra-high performance, dual-core M7 and above processors can also achieve the effect of battery life, allowing ultra-clear images to run smoothly. Summary of the Invention

[0009] A low-power, high-definition, large-color screen door lock, used in the field of smart door locks, is used to solve the contradiction between power consumption and screen resolution and smoothness of existing color screen smart door locks. It mainly includes:

[0010] The low-power, high-definition, large-color screen door lock system includes:

[0011] An integrated circuit motherboard, which includes at least: one low-power microprocessor, one high-performance microprocessor, memory, a large high-definition color display, a touch-sensitive screen, a motor driver, a power supply, and one or more or all of the peripheral modules selected from the group consisting of a fingerprint module, a facial recognition module, a palm vein module, a cat's eye module, and a radar module;

[0012] The low-power microprocessor remains powered, spending most of its time in sleep mode, and communicates with the touchscreen. The high-performance microprocessor and touchscreen can be connected in parallel or forwarded through the low-power microprocessor. Most of the time, the high-performance microprocessor and the large, high-definition color display communicate via MIPI, SPI, or 8080. Most of the time, it is completely powered off and requires powering up under the control of the low-power microprocessor. When the touchscreen senses a gesture, it automatically wakes up the low-power microprocessor, which then controls the power supply to the large, high-definition color display and the high-performance microprocessor, powering both.

[0013] The motor driver is used to drive the motor inside the door lock mechanical structure, thereby controlling the opening and closing of the door lock; the fingerprint module is connected to a low-power microprocessor, and the two communicate through serial ports or SPI ports, and can wake up the low-power microprocessor; the face module can be connected to a low-power microprocessor or a high-performance processor, and the two communicate through serial ports or SPI ports; the palm vein module is connected to a low-power microprocessor, and the two communicate through serial ports or SPI ports, and can wake up the low-power microprocessor; the cat's eye module is in a long-term power supply state and can be connected to a low-power microprocessor or a high-performance processor, and the two communicate through serial ports or SPI ports; the radar module can be connected to a low-power microprocessor through an IO port or a serial port. When the radar detects an object approaching, the low-power microprocessor is woken up through the IO port or the serial port.

[0014] The above components and modules are combined according to a certain rule, in which the touch sensor chip is connected to the low-power microprocessor and the high-performance microprocessor at the same time, which is used to achieve: when the touch screen is in low-power detection mode, it can sense the capacitance change of the touch screen; the change of the touch screen can directly wake up the low-power microprocessor; the low-power microprocessor can control the power on and off of the high-performance microprocessor; the low-power microprocessor can power on and off the high-definition color large display; the low-power microprocessor can power on and off the high-performance microprocessor; the low-power microprocessor can detect the interrupt signal of the peripheral module and wake up;

[0015] Mechanical parts include: front panel, rear panel, lock body, battery, clutch mechanism, and handle, which have different shapes and performances according to different designs.

[0016] The method for implementing a low-power, high-definition, large-color screen door lock includes the following steps:

[0017] 1) Put the touch screen into low-power sleep mode and detect specific touch gestures or areas;

[0018] 2) Wake up the low-power microprocessor when a specific touch gesture or area is detected;

[0019] 3) The low-power microprocessor powers on the high-performance microprocessor and the high-definition color large display, and lets the high-performance microprocessor run the preset graphical interface;

[0020] 4) High performance for the microprocessor to detect changes in the touch screen and other peripheral modules;

[0021] 5) When no changes are detected on the touch screen or other peripheral modules for a long time, the low-power microprocessor is notified to enter shutdown mode;

[0022] 6) The low-power microprocessor powers off the large high-definition color display and high-performance processor and enters a standby sleep state.

[0023] In a low-power, high-definition, large-color screen door lock, the camera signal of the cat's eye module or the face module can be transmitted to the high-definition color large display screen through methods including USB communication. The transmission format can be a variety of formats including Mjpeg, H.264, and H.265.

[0024] In low-power, high-definition, large-color screen door locks, the low-power microprocessor is only responsible for handling low-end tasks, while the high-performance processor handles high-end tasks including graphical interfaces and complex calculations.

[0025] In a low-power, high-definition, large-color screen door lock, other peripheral modules can also wake up the low-power microprocessor and power on the high-performance microprocessor through the low-power microprocessor.

[0026] In a low-power, high-definition, large-color screen door lock, there can be multiple high-performance microprocessors.

[0027] In a low-power, high-definition, large-color screen door lock, the touch screen signal is only connected to the low-power microprocessor and forwarded by the low-power microprocessor to the high-performance processor for processing.

[0028] In a low-power, high-definition, large-color screen door lock, the touch screen signal can be connected in parallel to a low-power microprocessor and a high-performance microprocessor at the same time. When connected in parallel, when the high-performance processor is running, the low-power microprocessor can also directly shield the touch screen signal.

[0029] In the low-power, high-definition, large-color screen door lock, the video signal of the face module is transmitted to the high-definition, large-color screen and displayed through video protocols including Mjpeg / H.264 / H.265.

[0030] In a low-power, high-definition, large-color screen door lock, the facial recognition module records the user's face in the following steps:

[0031] 1. The video image of the face module is displayed on a large high-definition color display, and the face module recognizes the current face angle;

[0032] 2. The facial recognition module sends the current user's facial angle to the high-definition color display and prompts the user to adjust the movements as needed, including tilting the head left, right, up, and down;

[0033] 3. The facial recognition module collects the user's feature values ​​at all angles and stores them internally;

[0034] 4. The face recognition module prompts the user on the large high-definition color display screen that the entry is successful.

[0035] In low-power, high-definition, large-color screen door locks,

[0036] By using the present invention, the following effects can be achieved:

[0037] 1. Extremely low power consumption: Because in most cases, the door lock's high-performance processor and color display are completely shut down, the standby power consumption will be very low.

[0038] 2. Extremely high performance: Because power consumption does not need to be considered in standby mode, a high-performance processor can be used to perform complex calculations when the door lock is awakened.

[0039] 3. Extremely convenient operation: Because most operations are on the high-definition large color display and support touch, when operating, there is no need to listen to the voice and press the corresponding button according to the voice prompts to set the door lock like traditional door locks.

[0040] 4. Extremely high-end grade: Because the traditional capacitive digital buttons have been removed and replaced with a comprehensive high-definition color large display, it is equivalent to the door lock entering the iPhone era from the traditional Nokia era, which greatly improves the sense of luxury of the door lock.

[0044] Figure 1 This is a schematic diagram of the composition of the integrated circuit motherboard of the present invention. The low-power, high-definition, large-color screen door lock has an integrated circuit motherboard as its main control part. The integrated circuit motherboard includes at least one or more or all of the peripheral modules: a low-power microprocessor 101, a high-performance microprocessor 102, a memory 103, a large high-definition color display 104, a touch-sensitive screen 105, a motor driver 106, a power supply 107, a fingerprint module 108, a facial module 109, a palm vein module 110, a cat's eye module 111, and a radar module 112.

[0045] The low-power microprocessor 101 remains powered, mostly dormant, and communicates with the touch-sensitive chip 105. The high-performance microprocessor 102 and touch-sensitive screen 105 can communicate in parallel or through the low-power microprocessor 101. In most situations, the high-performance microprocessor 102 and the large, high-definition, color display 104 are completely powered off and require power-up control by the low-power microprocessor 101. When the touch-sensitive screen 105 senses a gesture on the screen, it automatically wakes up the low-power microprocessor 101, which then controls the power supply to the large, high-definition, color display 104 and the high-performance microprocessor 102, powering them both.

[0046] The motor driver 106 is used to drive the motor in the door lock mechanical structure 113, thereby controlling the opening and closing of the door lock; the fingerprint module 108 is connected to the low-power microprocessor 101, and the two communicate with each other through a serial port or an SPI port, and can wake up the low-power microprocessor 101; the face module 109 can be connected to the low-power microprocessor or the high-performance processor 102, and the two communicate with each other through a serial port or an SPI port; the palm vein module 110 is connected to the low-power microprocessor 101, and the two communicate with each other through a serial port or an SPI port, and can wake up the low-power microprocessor 101; the cat's eye module 111 is in a long-term power supply state and can be connected to the low-power microprocessor 101 or the high-performance processor 102, and the two communicate with each other through a serial port or an SPI port; the radar module 112 can be connected to the low-power microprocessor 101 through an IO port or a serial port. When the radar module 112 detects an object approaching, it wakes up the low-power microprocessor 101 through the IO port or the serial port.

[0047] The above components and modules are combined according to certain rules to achieve the following: when the touch screen is in low-power detection mode, it can sense the capacitance changes of the touch screen; the changes of the touch screen can directly wake up the low-power microprocessor; the low-power microprocessor can control the power on and off of the high-performance microprocessor; the low-power microprocessor can power on and off the high-definition color large display; the low-power microprocessor can power on and off the high-performance microprocessor; the low-power microprocessor can detect the interrupt signal of the peripheral module and wake up.

[0048] Figure 2 This is a flowchart of the implementation of the present invention. The implementation method of the low-power, high-definition, large-color screen door lock needs to include the following steps:

[0049] Step 201: The touch screen enters a low-power sleep mode and detects specific touch gestures or areas. Touch screens typically have multiple detection modes, including normal mode and sleep mode. In sleep mode, the touch screen can detect finger gestures on the screen, such as sliding a finger a certain distance, double-tapping the screen, or drawing a circle on the screen. In this mode, the coordinates of the touch screen's sensing area are not sent to the microprocessor, but the microprocessor can be woken up.

[0050] Step 202: When a specific touch gesture or area is detected, the low-power microprocessor is awakened. The touch screen can wake up the low-power microprocessor through an IO port, a serial port, or an SPI port.

[0051] Step 203: The low-power microprocessor powers up the high-performance microprocessor and the large HD color display, and instructs the high-performance microprocessor to run a preset graphical interface. Once powered up, the low-power microprocessor quickly controls the power supply to the high-performance microprocessor and the large HD color display, powering them up. Once the high-performance microprocessor is running, due to its higher performance, it can quickly run the desired user interface and the video signal from the facial recognition module or cat's eye module on the large HD color display.

[0052] Step 203: The high-performance microprocessor detects changes in the touch screen and other peripheral modules. Because the high-performance microprocessor is already powered on and running, it can detect and receive signals from the touch screen in real time, and thus display the corresponding interface according to the position of the user's finger, etc.

[0053] Step 204: When no changes are detected on the touch screen or other peripheral modules for a long time, notify the low-power microprocessor to enter shutdown mode: After a person successfully unlocks the door and enters the room, generally, there is no one outside the door lock. Through a certain timeout design, if there is no action after a certain period of time, the high-definition color large display screen begins to enter the power-off preparation state, and at the same time notifies the low-power microprocessor to power off itself. This step can also be handled by a low-power microprocessor. If the low-power microprocessor does not detect changes on the touch screen or other peripheral modules for a long time, it notifies the high-performance processor to automatically power off the low-power microprocessor and the high-definition color large display screen.

[0054] Step 205: The low-power microprocessor powers off the large high-definition color display and the high-performance processor, and enters a standby sleep state. Because the low-power microprocessor completely powers off the large high-definition color display and the high-performance processor, they do not consume any power at this time, thus keeping the power consumption of the entire door lock very low.

[0055] Figure 3 This is a flowchart of the face module of the present invention when recording a user's face. The implementation of this function requires the following steps:

[0056] Step 301: The face module's video image is displayed on a large, high-definition color display, while the face module identifies the current face angle. The camera signal from the cat's eye module or face module can be transmitted to the large, high-definition color display via USB communication, in various formats including MJPEG, H.264, and H.265.

[0057] Step 302: The facial recognition module transmits the current user's facial angle to the large HD color display and prompts the user to adjust their movements, including tilting their head left, right, up, and down, as needed. The facial recognition module's built-in algorithm detects the user's recorded angle and position in real time. This prompt is then sent to a high-performance microprocessor via a serial or SPI port, and then displayed on the large HD color display. This streamlines the facial registration process, which previously lacked a real-time facial image.

[0058] Step 303: The face module collects the feature values ​​of the user at all angles and stores them in the face module. Different people's faces have different feature values, and the feature values ​​are different according to different algorithms, so the feature values ​​are stored in the face module.

[0059] Step 304: The facial module notifies the user on the large HD color display screen that the data entry is successful. After the facial module completes the entire data acquisition process, the result is fed back to the high-performance processor, which then displays the successful data entry result on the large HD color display screen.
