[0021] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present disclosure. The drawings only show components related to the present disclosure rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0022] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, one skilled in the art will appreciate that aspects may be practiced without these specific details.
[0023] See also Figure 1 The network control display shown is suitable for driving the image display of the train platform display. The display includes a display screen, a control box and an image controller connected to the control box, wherein:
[0024] The control box is used for data processing and is provided with a first power converter and a second power converter, which effectively utilizes the resources of the train itself, can omit some or all of the power components, and improve the utilization rate of space. For example, the first power converter is connected to the train power supply for voltage conversion and provides DC-110V power to the control box, such as using a power line + power converter mode;
[0025] The image controller is installed in an integrated manner with the display screen, receives instructions sent by the control box and interacts with the display screen data to control the image display on the display screen. The second power converter is electrically connected to the image controller for voltage conversion and providing DC-12V power to the image controller. To avoid the use of traditional "big butt" type displays, the control box does not need to be set in the driver's console, which improves the overall display efficiency.
[0026] As a specific implementation method provided in this case, the control box performs MVB and Ethernet data communication with the train system or equipment, can receive and analyze the data transmitted by the train system, generate a video signal, and transmit it to the image controller via an HDMI cable.
[0027] As a specific implementation method provided in this case, the control box is connected to the image controller through a signal line in a two-way communication manner. For example, the brightness of the display screen can be adjusted by transmitting through the signal line, avoiding the use of the image controller and reducing heat generation.
[0028] Further, the image controller includes an integrated processing circuit board ( Figure 3 The integrated processing module in the HDMI cable is used to convert the data transmitted by the HDMI cable into LVDS image data and control the display screen to display it. The integrated processing circuit board analyzes and calculates the image display separately to avoid the display from generating additional heat.
[0029] Further, such as Figure 2 As shown, the display is equipped with a buzzer, which is electrically connected to the image controller, and the image controller is electrically connected to a "watchdog" circuit. When the image controller fails or is abnormal, the "dog barking" signal triggers the buzzer to operate.
[0030] As a specific implementation method provided in this case, the display screen is a human-computer interactive display device. The signals or data generated by the display screen in a human-computer interactive manner are transmitted to the control box through the image controller. The control box transmits the output signal through an HDMI cable, avoiding the use of an integrated processing circuit board.
[0031] Furthermore, the display screen is equipped with a light sensor for collecting ambient light parameters. The data collected by the light sensor is transmitted to the control box through the image controller. The control box calculates and outputs a control signal, which is transmitted to the image controller through a data line. The display screen is also equipped with an indicator light for network control of the display status information. The status signal output by the control box is transmitted to the image controller through a data line, and the image controller controls the indicator light status according to the status signal.
[0032] Furthermore, the display screen is equipped with a backlight panel for adjusting brightness, and the backlight panel is used to adjust the display brightness of the display screen according to the control signal output by the control box.
[0033] Furthermore, the image controller is used to convert the received HDMI signal into an LVDS signal and transmit it to the display screen.
[0034] Furthermore, the control box receives the train operating parameters transmitted by the train system, including the train door status information and the air conditioning system operation status information, etc. The control box is also connected to the buzzer, and data anomalies also trigger the buzzer to operate, such as the door is not closed or the air conditioning is faulty, or a red, yellow and green indicator light is installed on the display screen for fault feedback.
[0035] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
