Door direction display control system for LCD panel in electric vehicle cabin

The present invention relates to a system for controlling the opening direction of the LCD panel of an electric vehicle cabin, and in particular, a front LCD panel positioned to face the traveling direction of the electric vehicle and a rear LCD panel positioned to face the opposite direction of the traveling direction are configured together. In the case of the room information providing device, it is possible to display the electric vehicle door opening direction indication on the front LCD panel and the rear LCD panel at the same time as the image data of the arrow on the front LCD panel and the rear LCD panel at the same time. The present invention relates to a control system for opening direction indication of an LCD panel of an electric vehicle cabin, which is suitable for use.

Recently, in the electric vehicle cabins such as subways and trains, it is common to find a room information providing device that provides station information, advertisements, and multimedia information by hanging on the ceiling of the room.

1 is a conceptual diagram for explaining the problem of the opening direction display of the electric vehicle cabin LCD panel 10 ', 10' 'according to the prior art.

As shown in FIG. 1, the room information providing device A includes a plurality of LCD panels 10 ′ and 10 ″, and the LCD panels 10 ′ and 10 ″ are provided with various advertisements, news, and TVs. It provides information on the subway or train, including broadcasting.

Then, the LCD panels 10 'and 10' 'are front LCD panels 10' positioned to face the traveling direction of the electric vehicle and rear LCD panels 10 '' positioned to face opposite directions of the traveling vehicle. It is configured to display various images provided from an external video server (not shown).

In addition, various technologies have been disclosed for displaying the direction in which the door of the electric vehicle is opened. For example, a technology for displaying using an LED light has been developed, or there has been a technology for displaying the opening direction based on text.

However, in order to display the opening direction as an arrow image, a technology for directly transmitting the arrow image provided by the video server to the LCD panels 10 'and 10' 'was attempted. However, in such a case, the video server simply displays the image. Since only information is transmitted at the same time, the front LCD panel 10 'and the rear LCD panel 10' 'provided at the back and the opposite direction of the electric vehicle, respectively, have one LCD panel 10 as shown in FIG. ') Is the right direction, but the opposite panel (10 ``) has the problem of the technology that the arrow is displayed in the opposite direction to the wrong display, so until now the technology to implement the opening direction display in the image has not been developed.

The present invention was created in order to solve the technical problem that has not been realized in the prior art as described above, the problem of the opening direction display control system of the electric vehicle cabin LCD panel according to the present invention, the driving direction of the electric vehicle In the case of the room information providing device, which consists of the front LCD panel positioned to face the rear panel and the rear LCD panel positioned to face in the opposite direction of the direction of travel, the wrong information is not displayed independently of the original image information screen. The present invention provides a system for controlling the opening direction of the LCD panel of an electric vehicle cabin, which is suitable for displaying the front door opening direction indication on the front LCD panel and the rear LCD panel as image data of an arrow.

Opening direction display control system of the electric vehicle cabin LCD panel of the present invention for achieving the above object, the vehicle control information and TCMS (Train Control Monitoring System) storing the station information and station information, and the vehicle operation information received from the TCMS A controller that processes and transmits data to the control board so that the control board can recognize and process reverse information, a video server that provides a VGA (Video Graphics Array) signal displayed on the LCD panel, and the video server A VGA divider for distributing the VGA signal to a plurality of LCD panels, a control board for controlling the operation state of the LCD panel and the power supply of the LCD panel, and transmitting the VGA signal received from the VGA divider to the LCD panel. A / D board which converts digital signal to LCD panel for output, front LCD panel which is located to face the driving direction of electric vehicle, and traveling direction It is configured in the opposite direction by the rear LCD panel which is located so as to face comprising: a plurality of LCD panel for displaying an image provided by the video server,

The TCMS outputs the opening direction information and the destination information to the setting unit, and the setting unit transmits the processing direction data to the control board so that the control board recognizes and processes the opening direction information and the destination information received from the TCMS, and controls the control. The board generates an opening direction control signal and outputs it to the A / D board based on the opening direction information received from the setter and the destination information so that the opening direction indication of the doors displayed on the front LCD panel and the rear LCD panel is identical. The A / D board generates an opening direction display image signal according to the opening direction display control signal received from the control board, and outputs the generated video signal to the LCD panel.
