Description

Technical Field

[0001] This invention relates to the field of display control technology, specifically to a multi-mode compatible visualization control platform and its control method. Background Technology

[0002] With the rapid development of display technology, large-screen display devices have become widely used in various fields such as conference communication, business exhibitions, security monitoring, and education and training due to their wide display field and clear picture quality. As the core control component of large-screen display devices, the large-screen control terminal bears the key responsibilities of receiving control commands, driving the screen display, and coordinating the work of various components. Its performance directly determines the overall effect, operational stability, and user experience of the large-screen display.

[0003] Currently, large-screen control terminals on the market generally suffer from the following core defects, making it difficult to meet the efficient control needs in diverse scenarios:

[0004] 1. Poor compatibility: Most control terminals adopt a single control method, only supporting wired connection control (such as only supporting HDMI protocol) or single wireless protocol control (such as only supporting Wi-Fi), which cannot be adapted to different types of external control devices (such as computers, mobile phones, tablets, dedicated remote controls) and large-screen display devices, thus limiting the applicable scenarios;

[0005] 2. Slow response speed: The core processing chip of the control terminal has insufficient performance. When performing high-frequency operations such as switching multiple windows, zooming the screen, and switching signal sources, stuttering and delays are likely to occur, which seriously affects the user's operation continuity and user experience.

[0006] 3. Power consumption and heat dissipation issues are prominent: The existing control terminal lacks a dynamic power consumption adjustment mechanism, and maintains a high power supply regardless of whether it is under light load or full load, resulting in high power consumption; at the same time, the heat dissipation design is rudimentary, and after long-term use, it is prone to overheating, which can lead to a decline in equipment performance, frequent failures, and a shortened equipment lifespan.

[0007] 4. Insufficient stability and reliability: It lacks a sound fault detection and self-protection mechanism, and cannot monitor the working status of each module in real time. When faults such as abnormal voltage, current fluctuation, or communication interruption occur, it cannot provide timely warnings and handle them, which can easily lead to the expansion of faults and affect the normal operation of the large screen display system. Summary of the Invention

[0008] To address these issues, this invention provides a multi-mode compatible visualization control platform and its control method to solve the technical problems of poor compatibility, slow response speed, high power consumption, and insufficient stability in existing large-screen control terminals.

[0046] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In order to solve the technical problems of poor compatibility, slow response speed, high power consumption and insufficient stability of the existing large screen control terminals.

[0048] refer to Figure 1 and Figure 2 This invention discloses a multi-mode compatible visual control platform, comprising: a main control module 1, a multi-mode communication module 2, a display driver module 3, a power management module 4, a heat dissipation module 5, and a fault detection module 6; the main control module 1 is electrically connected to the multi-mode communication module 2, the display driver module 3, the power management module 4, the heat dissipation module 5, and the fault detection module 6 respectively, and is used to receive and process control commands and coordinate the collaborative work of each module.

[0049] In this embodiment, the main control module 1 uses an ARM Cortex-A76 processor. This processor uses a 7nm process and has a main frequency of up to 2.8GHz. It features high performance and low power consumption and can quickly process multiple control instructions and data to meet the real-time control requirements of the large screen control terminal.

[0050] The multi-mode communication module 2 is used to realize multi-protocol communication between the control terminal and external control devices and large-screen display devices. It includes a wired communication unit, a wireless communication unit, and a communication protocol conversion unit. The wired communication unit supports three protocols: HDMI 2.1, DP 1.4, and USB-C 3.2, enabling high-speed wired data transmission. The wireless communication unit supports three protocols: Wi-Fi 6, Bluetooth 5.2, and 5G, meeting the wireless control needs of different distances and scenarios. The communication protocol conversion unit uses a dedicated protocol conversion chip to realize data conversion between different communication protocols, ensuring accurate transmission of control commands.

[0051] The display driver module 3 is used to drive the large-screen display device to display images according to the instructions of the main control module 1. It includes a resolution adaptation unit and a color calibration unit. The resolution adaptation unit adopts an adaptive resolution recognition algorithm, which can automatically identify the resolution of the large-screen display device (supporting multiple resolutions from 1080P to 8K) and adapt it accordingly. The color calibration unit adopts 3D LUT color calibration technology, which can accurately calibrate the color parameters such as brightness, contrast, and color gamut of the displayed image to ensure the color reproduction of the displayed image.

[0052] The power management module 4 provides a stable power supply to all modules on the control side, including a power conversion unit and a power consumption regulation unit. The power conversion unit uses a high-efficiency DC-DC converter chip, which can convert the externally input 12V-24V DC voltage into the 3.3V, 5V, and 1.8V operating voltages required by each module, with a conversion efficiency of over 95%. The power consumption regulation unit dynamically adjusts the power supply by monitoring the operating current and voltage of each module in real time. When the control side is in standby or light load state, it reduces the power supply to achieve low-power operation.

[0053] The heat dissipation module 5 is used to dissipate heat from the control terminal, including a temperature acquisition unit, a cooling fan, and a heat-conducting component. The temperature acquisition unit uses a high-precision thermistor sensor to collect the internal temperature data of the control terminal in real time and transmit it to the main control module 1; the cooling fan is a silent brushless fan that supports multiple speed adjustments; the heat-conducting component is made of graphene, which has a thermal conductivity of up to 5000 W / (m·K), and can quickly conduct heat from inside the control terminal to the cooling fan for exhaust, ensuring that the internal temperature of the control terminal remains stable below 50℃.

[0054] The fault detection module 6 is used to detect the operating status of each module in the control terminal, including a voltage detection unit, a current detection unit, a communication status detection unit, and a storage unit. The voltage and current detection units detect the supply voltage and operating current of each module, respectively. When the voltage or current exceeds a preset range, they send a voltage or current abnormality signal. The communication status detection unit monitors the connection status of the communication link in real time. When a communication interruption or data transmission error is detected, it sends a communication abnormality signal. The storage unit 64 uses a Flash memory chip to store fault detection data and fault logs, facilitating later maintenance and troubleshooting. When an abnormality is detected, the fault detection module 6 sends a fault warning signal to the main control module 1. The main control module 1 then executes corresponding protection measures based on the fault warning signal, such as power-off protection, derating, or module restart.

[0055] Corresponding to the multi-mode compatible visualization control platform disclosed above, this invention also discloses a control method for the multi-mode compatible visualization control platform. The following details the control method for the multi-mode compatible visualization control platform disclosed in this invention, in conjunction with the multi-mode compatible visualization control platform described above.

[0056] refer to Figure 3 and Figure 4 This invention discloses a control method for a multi-mode compatible visual control platform, comprising:

[0057] S1. Initialization settings: After the control terminal is powered on, the main control module 1 initializes the multi-mode communication module 2, display driver module 3, power management module 4, heat dissipation module 5 and fault detection module 6, and completes the parameter configuration of each module, including communication protocol parameters, resolution adaptation range, color calibration parameters, power consumption threshold, temperature threshold (such as heat dissipation trigger threshold 50℃, heat dissipation stop threshold 30℃) and fault detection threshold, etc.

[0058] S2. Communication Connection Establishment: The multi-mode communication module 2 automatically scans external control devices (such as computers, mobile phones, tablets, remote controls, etc.) and large-screen display devices, identifies the device type through the device's identification information, and then selects the corresponding communication protocol to establish a communication connection. For example, when the external control device is a computer, HDMI or USB-C wired protocol connection can be selected; when the external control device is a mobile phone, Wi-Fi or Bluetooth wireless protocol connection can be selected.

[0059] S3. Control Command Reception and Processing: The main control module 1 receives control commands sent by external control devices through the multi-mode communication module 2. These control commands include screen switching commands, resolution adjustment commands, color adjustment commands, signal source switching commands, and power on / off commands. The main control module 1 parses and prioritizes the control commands, giving priority to emergency control commands (such as emergency power off commands, fault reset commands, and emergency screen switching commands). Then, based on the parsing results, it generates corresponding drive commands and control signals.

[0060] S4. Display Driver Control: The display driver module 3 drives the large-screen display device to display images according to the driving instructions generated by the main control module 1. The resolution adaptation unit automatically identifies the resolution of the large-screen display device and adapts the resolution of the displayed image to match the resolution of the large screen; the color calibration unit calibrates the brightness, contrast, color gamut, and other parameters of the displayed image according to preset color calibration parameters or color adjustment instructions sent by external control devices to ensure that the displayed image is clear and the colors are accurate.

[0061] S5. Real-time Monitoring and Adjustment: During operation at the control end, the voltage detection unit, current detection unit, and communication status detection unit of the fault detection module 6 monitor the operating status of each module in real time and transmit the detection data to the main control module 1; the temperature acquisition unit of the heat dissipation module 5 collects the internal temperature data of the control end in real time and transmits it to the main control module 1. The main control module 1 analyzes the detection data. If abnormal voltage, current, or communication status is detected, a fault warning signal is issued (through sound, light, or by sending warning information to external control devices), and corresponding protection measures are implemented, such as restarting the abnormal module, reducing the module's operating power, or directly cutting off power. If the temperature data is greater than a preset threshold (e.g., 50℃), the main control module 1 controls the cooling fan to increase its speed to accelerate heat dissipation; if the temperature data is less than a preset threshold (e.g., 30℃), the main control module 1 controls the cooling fan to decrease its speed or stop working to reduce power consumption.

[0062] S6. Communication Disconnection: When an external control device issues a disconnect command, the multi-mode communication module 2 disconnects from the external device. If the communication status detection unit detects an abnormal communication link and it cannot be restored within a preset time (e.g., 10 seconds), the multi-mode communication module 2 automatically disconnects the communication link. After communication disconnection, the control terminal enters a low-power standby state, reducing power consumption and retaining only the necessary detection modules for operation.

[0063] The large-screen control terminal and control method of this invention achieve flexible connection of multiple devices and multiple protocols through a multi-mode communication module, thereby improving compatibility; adopting a high-performance main control module and optimized control logic improves response speed and display effect; reducing power consumption and extending equipment life through dynamic power consumption adjustment and efficient heat dissipation design; and improving equipment stability and reliability through a comprehensive fault detection and protection mechanism, making it widely applicable to various large-screen display control scenarios.

[0064] The embodiments of the present invention have the following beneficial effects:

[0065] 1. Significantly improved compatibility: Through the integration of multiple wired and wireless protocols via a multi-mode communication module, it can be adapted to different types of external control devices such as computers, mobile phones, tablets, and remote controls, as well as large-screen display devices with different resolutions and interface types, covering a wide range of applicable scenarios;

[0066] 2. Fast response speed: It adopts a high-performance ARM Cortex-A76 processor, coupled with optimized instruction parsing and priority sorting logic, to achieve fast processing of control instructions. The latency of operations such as screen switching and resolution adjustment is less than 50ms, improving the smoothness of user operation.

[0067] 3. Low power consumption and efficient heat dissipation: The dynamic power consumption adjustment mechanism can adjust the power supply in real time according to the working status, reducing standby power consumption by more than 70%; the heat dissipation design of graphene heat-conducting components and intelligent speed fan ensures long-term stable operation of the equipment and extends its service life to more than 5 years.

[0068] 4. High stability and reliability: The comprehensive fault detection module can monitor voltage, current and communication status in real time, provide timely warnings and handle faults to prevent them from escalating; the fault log storage function facilitates later maintenance and reduces operation and maintenance costs.

[0069] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
