Description

Tunnel Vision System

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for a tunnel, and more particularly, an image displayed on one large screen due to a state in which two rows of vertically arranged light emitting diode display units are sequentially lit according to the speed of a vehicle traveling in a tunnel or underground. It relates to a display device for a tunnel that can provide advertising, promotion and / or information in the same effect as seeing.

In general, advertising and public relations have been felt to target a large number of people on the move by means of transportation, and as a result, a large number of people pass by the road during the day or night by installing a signboard on the roof of an elevated area or building. I could see it in the middle.

Conventional display board is a means of displaying letters and pictures by combining the module (MODULE) of the light emitting diode bundle (MODULE) constituting the display board, the light-emitting diode set (SET) and the light-emitting diode to reset (RESET) It has a structure that expresses characters, animations and graphics by storing various formats in a program in advance and outputting each input channel data in order.

The conventional electronic display board configured as described above has a control circuit for controlling the stop time for each display screen described above and a stop position control or display technique in the control unit. It consists of an electronic signboard, which is fixed and attached to a certain place to notify people of local information, public service announcements, and commercial advertisements from a distance or a short distance.

However, the display screen of the conventional electronic display board requires a certain distance of a long distance or a short distance, and due to the fixed screen configuration, it is suitable for a passenger in a subway running a tunnel section between a station and a station that is operating at a close distance due to the fixed screen configuration. In the case of installing a signboard on the driving section wall, the distance of subway and the close distance between the subway and the tunnel section of the driving section are difficult to identify by the human vision, which limits the transmission of information such as text and graphics. Since the above-described combination of a plurality of modules there is a problem in terms of cost burden in proportion to the display screen size in terms of economics.

Therefore, Japanese Patent Application Laid-open No. Hei 9-134142 (a method and apparatus for displaying traffic information and the like for passengers of cars walking in a tunnel) has been proposed.

This displays traffic information and the like so that the driver of the vehicle can read from a distance far enough with a natural line of sight in a tunnel with very little space provided with the display panel protruding on the road side.

Multiple bone-shaped indicators with multiple light-emitting cells arranged in a straight line at tight intervals are installed, and these multiple indicators are installed vertically at large intervals along the wall of the tunnel. The luminous directivity and the installation direction are installed so that the light from each rod indicator can be clearly seen and recognized by the people in the car traveling toward this installation part. The target screen area is formed along the tunnel wall according to the arrangement of each rod indicator, and the plurality of light emitting cells arranged vertically and horizontally in the target screen area are driven in a random scrolling manner according to the bitmap type image data. To display the image in a scrolling manner.

However, the method of displaying traffic information and the like for a passenger of a vehicle walking in a conventional tunnel as described above and the apparatus by scrolling these rod indicators in a state in which a plurality of rod indicators are arranged side by side to form a target screen area. Since it was necessary to display the image of advertisement or promotion while driving by the display method, a lot of installation costs are required to form the target screen area by a plurality of rod indicators, and a lot of time and cost are also required to maintain these rod indicators. There was a problem.

Therefore, Patent Application No. 10-1999-0011922 dated April 6, 1999 (a signboard displayed in proportion to the speed) was proposed.

In order to be recognized by the graphic and character afterimage to be indicated by the diode flickering, a plurality of light emitting diodes arranged at regular intervals are arranged in rows or rows in a row, so that a plurality of light emitting diodes are arranged in one direction or in circular motion, rotational motion or reciprocation motion.

A speed measurement medium unit connected to the control unit by means of

It is composed of power supply devices for supplying power to the diode device to display the afterimage using only the speed of the traffic engine, or to control the LED flashing control or the diode device in proportion to the detection speed to provide the display board. It was made.

However, since the display panel is displayed in proportion to the conventional speed as described above, the diode device unit is driven in a circular motion, a rotational motion, or a reciprocating motion through the driving device part by the speed measured by the speed measuring medium part. In order to continuously move the diode unit according to the speed of operation in the region, a lot of exercise is required, as well as a lot of unnecessary devices need to be additionally installed for the exercise, which requires a lot of manpower and time for maintenance. There was a problem.

Accordingly, the present invention has been made to solve the conventional problems as described above, one large by the state in which two rows of vertical light emitting diode display unit is sequentially lighted according to the speed of the vehicle traveling in the tunnel or underground. It is an object of the present invention to provide a tunnel display device capable of providing advertisements, promotions and / or information with an effect such as viewing an image displayed on a screen.
