Description

Technical Field

[0001] This utility model belongs to the field of video security monitoring technology, and in particular relates to a multi-functional video wall control keyboard device. Background Technology

[0002] In the field of modern security monitoring, video surveillance centers bear the crucial responsibility of real-time monitoring and ensuring security in various locations. With the continuous development of monitoring technology, the types and quantities of monitoring equipment are increasing daily, making the need for centralized control and efficient management of these devices increasingly urgent. As a key device for the centralized display of monitoring images, the video wall relies on its accompanying control keyboard as a core tool for convenient operation. In this industry context, the performance and functionality of the control keyboard directly impact the overall operational efficiency and user experience of the monitoring system.

[0003] Current control keyboards are designed with limited functionality, often developed for specific purposes, thus limiting their application scenarios. In complex monitoring systems, they struggle to achieve unified control of various device types, requiring multiple keyboards, which is cumbersome and costly. They generally lack a built-in large-screen display, relying on external displays to show operational status. In special scenarios, such as peripheral device failures or temporary monitoring, they cannot provide timely operational feedback, affecting the timeliness and accuracy of monitoring, increasing equipment costs, and reducing ease of operation. Their internal structure separates electronic components and results in numerous and long signal cables, which not only causes signal quality issues, such as image transmission stuttering, delays, and blurry images, affecting monitoring effectiveness, but also significantly increases maintenance difficulty, costs, and time, reducing equipment reliability.

[0004] To address these issues, we provide a multi-functional video wall control keyboard device. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional video wall control keyboard device, which solves the problems of limited control keyboard functions, lack of local large-screen display, and poor signal quality and maintenance difficulties caused by the internal structure in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a multifunctional video wall control keyboard device, comprising an upper shell, a display screen fixedly connected to one side of the upper shell surface, a joystick fixedly connected to the other side of the upper shell surface, silicone buttons fixedly connected to the bottom of the upper shell surface, a base plate fixedly connected to the rear end of the upper shell, a shaped bracket fixedly connected to the rear end of the display screen, a main control board fixedly connected to the rear end of the shaped bracket, and a button driver board fixedly connected to the rear end of the silicone buttons. The upper shell serves as the main structure supporting other components. A 5-inch high-definition display screen with a resolution of 800*600 is mounted on its surface, used to display the operation interface and monitoring screen in real time, allowing users to intuitively view operation feedback. When users perform operations such as switching camera views or setting screen splits, the display... The display screen can quickly show corresponding changes, improving ease of operation. The joystick uses an imported variable-speed four-dimensional joystick, which has a comfortable and good feel. Twisting the joystick can directly control the omnidirectional rotation of the pan-tilt unit, PTZ camera, etc., and zoom the lens. The speed control can also be adjusted according to the force applied by the joystick, providing users with a precise and flexible control experience. During monitoring, users can easily track target objects through the joystick and achieve fast and smooth lens movement. There are 40 silicone buttons with moderate softness and hardness. The surface has a slightly rounded convex structure suitable for finger pressing. The bottom of the buttons uses conductive black particles and an immersion gold plate to form a conductive path. Together with the button driver board, it can accurately transmit the button signals to the main control board for analysis and processing. These buttons have multiple functions, can quickly switch devices, and support button operation splicing. Image segmentation, real-time local display, and simultaneous output to an external HDMI display device greatly improves operational efficiency. The metal base plate, used in conjunction with the upper shell, completes the sealed structure. The base plate not only protects internal components but also acts as a counterweight, preventing the device from easily moving when placed on a table. Furthermore, the metal components conduct heat effectively, serving as a heat dissipation device to ensure stable operation over extended periods. The irregularly shaped bracket connected to the rear of the display provides dual support and fixation: it securely supports the display and also secures the control PCB board (main control board), ensuring the stability of all components and preventing vibration or shaking from affecting normal operation. The main control board connected to the rear of the bracket is a gold-plated PCB board with excellent conductivity. This is the core processing component of the entire device, receiving and processing signals from the joystick and silicone buttons. Running on a Linux system, it can operate 24 / 7. The VGA signal on the main control board is converted by the chip on the button driver board and displayed on the screen. The HDMI signal can be directly connected to an external monitor or display device. Furthermore, the main control board supports online programming of the stored program and replacement of the program chip, facilitating user upgrades. The inclusion of a DDR chip enhances processing power, making the system run faster. The button driver board, in conjunction with the silicone buttons, implements the button conductive switch function and integrates driver functionality to illuminate the display screen. The button driver board is relatively large, facilitating heat dissipation and providing a good working environment for the chip, while reducing the data and structural complexity of the PCB.To ensure stable equipment operation, the button driver board connects to the main control board via a data cable, accurately transmitting button signals to the main control board for processing.

[0008] The present invention is further configured such that four corners of the base plate are fixedly connected to feet, and one side of each foot is threaded with a flat-head self-tapping screw. The feet can effectively support the entire multi-functional TV wall control keyboard device, so that the device can be placed stably on a flat surface such as a desktop, avoiding the device from shaking due to unstable placement, which would affect the operating experience. The flat-head self-tapping screws threaded on one side of the feet are easy to install and can firmly fix the feet to the base plate, preventing the feet from loosening or falling off, and ensuring the stability and reliability of the device placement.

[0009] The present invention is further configured such that a fixed bracket is fixedly connected to the rear end of the joystick, and a first round-head self-tapping screw is threadedly connected to the rear end of the fixed bracket. The fixed bracket provides a stable support structure for the joystick, which can ensure that the joystick is fixed in position during operation and avoid affecting the accuracy of operation due to shaking. The rear end of the fixed bracket is threadedly connected by the first round-head self-tapping screw. This connection method is convenient for installation and disassembly, and can ensure that the fixed bracket is tightly connected to related components.

[0010] The present invention is further configured such that a flat-head machine screw is threaded to the rear end of the irregular bracket, and a second round-head self-tapping screw is threaded to the rear end of the main control board. The threaded connection of the rear end of the irregular bracket with the flat-head machine screw can firmly fix the irregular bracket in a suitable position, ensuring its dual support function for the display screen and the main control board. The second round-head self-tapping screw at the rear end of the main control board can stably install the main control board in the corresponding position, so that the main control board will not shift due to vibration or external force during operation.

[0011] The present invention is further configured such that a small round-head self-tapping screw is threaded to the rear end of the button driver board, and the button driver board is fixedly connected to the upper shell by the small round-head self-tapping screw. The installation method is simple and reliable. This connection method can firmly fix the button driver board to the upper shell, ensuring that it fits tightly with the silicone button and accurately receives and transmits button signals.

[0012] The present invention is further configured such that a data cable is plugged into one side of the button driver board, and the other side of the data cable is plugged into the main control board. The data cable establishes a data transmission channel between the button driver board and the main control board. When the user presses the silicone button, the button driver board accurately transmits the button signal to the main control board through the data cable. After receiving the signal, the main control board analyzes and processes it to realize the corresponding operation function.

[0013] The present invention is further configured such that an electronic signal line is plugged into one side of the joystick, and the other side of the electronic signal line is plugged into the main control board. When the user operates the joystick, the control signal generated therefrom is quickly and accurately transmitted to the main control board through the electronic signal line, ensuring the stability and timeliness of signal transmission.

[0038] Example 3

[0039] Please see Figure 6 This solution uses HiSilicon's Hi3536 chip, which supports H.265 and H.264 encoding, supports real-time encoding and decoding up to 1080P resolution, has high-performance video processing capabilities, and has a variety of image processing and enhancement functions. The chip runs on the Linux system, which is stable and reliable.

[0040] It adopts a DC12V power input, and the power is stepped down and converted inside the main control board 5 before being supplied to each circuit section.

[0041] The VGA signal on the main control board 5 is converted into a data video signal that the display screen 2 can recognize by the chip on the button driver board 9 for display.

[0042] The HDMI signal on the main control board 5 can be directly connected to the corresponding monitor or display device using an HDMI cable. If the external connection is normal, the green indicator light next to the HDMI port will light up.

[0043] When a user presses the silicone button 4 on the device, this signal is transmitted through the button driver board 9 to the designated IO port of the CPU on the main control board 5. The CPU judges and identifies the button, performs corresponding function processing according to different buttons, and provides timely feedback for each button press, such as a buzzer sounding, and the buzzer will continue to respond for the length of time the button is pressed.

[0044] The power supply and operating status of the main control board 5 can be judged by the indicator lights. A solid red light indicates normal power supply. When the green light below the red light flashes at a certain frequency, it indicates that the main control board 5 program is running normally. If the green light flashes rapidly, it indicates that the main control board 5 is malfunctioning. When powered on, pressing the reset button on the main control board 5 will cause the running indicator light to flash rapidly and the system software to restore its initial value.

[0045] The USB interface allows for the connection of an external mouse, enabling direct control on display screen 2.

[0046] Operating the joystick 3 in different directions will generate different data values, which will be sent to the main control board 5. The main control board 5 will convert the data into analog and digital signals and then process it.

[0047] External RS485 devices, such as alarm control panels, access controllers, and industrial sensor devices, can be connected through this interface. The main control board 5 responds to and processes the RS485 commands.

[0048] Gigabit Ethernet ports are used for communication with external networks, such as network cameras, network decoders, and network video control hosts.

[0049] The designated chip on the main control board 5, where the program is stored, supports online programming and program chip replacement, making it convenient for users to upgrade device functions, configure DDR chips, improve chip processing capabilities, and make the system run faster.

[0050] The working principle of this utility model is as follows: The user inputs control commands to the device by operating the silicone button 4 and the joystick 3. The conductive black particles at the bottom of the silicone button 4 form a conductive path with the gold plate, transmitting the button signal to the button driver board 9, and then to the main control board 5 via the data cable 16. The control signal generated by the joystick 3 is transmitted to the main control board 5 via the electronic signal line 17. After receiving these signals, the main control board 5 analyzes, identifies and processes them based on the built-in program and algorithm. For example, when the "switch camera" button is pressed, the main control board 5 will search for and switch to the screen of the specified camera according to the preset logic. When the joystick 3 is operated, the main control board 5 will issue corresponding rotation and zoom commands to the pan-tilt unit, PTZ camera and other equipment according to the different data values ​​generated by the joystick 3.

[0051] The device uses the Hisilicon Hi3536 chip, which supports H.265 and H.264 encoding and can perform real-time encoding and decoding of videos with resolutions up to 1080P. It has powerful video processing capabilities. The VGA signal on the main control board 5 is converted by the chip on the button driver board 9 and then displayed on the 5-inch high-definition display screen 2 to show the operation interface and monitoring screen. The HDMI signal on the main control board 5 can be directly connected to an external monitor or display device via an HDMI cable. When the external connection is normal, the green light next to the HDMI port will light up, realizing multi-screen synchronous display. When performing screen splitting, splicing and other operations, the Hi3536 chip will process the video signal according to the instructions of the main control board 5 to ensure that the picture is displayed correctly.

[0052] The main control board 5 runs stably on the Linux system and can control a variety of devices. Through built-in multiple protocols, it supports multiple control methods such as network IP, simulated RS485, and USB. When connected to external RS485 devices such as alarm hosts, access controllers, and industrial sensor devices, the main control board 5 responds and processes according to RS485 commands. It communicates with network cameras, network decoders, and network splicing hosts through the gigabit network port to realize remote control and data transmission of these devices. After connecting an external mouse through the USB interface, users can directly control the device on the display screen 2, similar to a computer mouse, which is convenient for various operations.

[0053] The device uses a DC 12V power input, which is stepped down and converted inside the main control board 5 to power various circuit parts. The power supply and operation status of the main control board 5 can be judged by indicator lights. A solid red light indicates normal power supply, a green light below the red light flashing at a certain frequency indicates normal program operation, and a rapidly flashing green light indicates abnormal operation. Pressing the reset button on the main control board 5 will cause the operation indicator light to flash rapidly, and the system software will restore the initial value to ensure that the device can quickly resume normal operation in abnormal situations.
