BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic backup controller and a route dual display panel system and a method of implementing the same. More particularly, the present invention relates to an automatic backup controller and a route dual display panel system, And an automatic backup controller and a route dual display panel system that can display data on a display board in the event of a route failure and display data at a lower end of a display board in the event of a failure between sub controllers, ≪ / RTI >

The electric signboard is used to display advertisement texts and information such as mutual, sales, sales items in shops, restaurants, companies, sales offices, etc. It is installed in a place where people's attention can be attracted to the exterior walls of the building. Recently, It is also widely used for the purpose of transmitting various information about the game, such as being installed in the same athletic field.

Generally, the electronic signboard has a structure in which a lighting device is provided inside a square frame, and a display panel in which characters, figures, symbols, images and the like are displayed is disposed on the entire frame.

Such an electronic signboard or electronic signboard is an electronic application display system for displaying various kinds of information in the state of visible stop or moving picture and is widely used for advertising, commercial, stadium, multi-purpose, traffic signal, And the size and the application system may be different depending on the application or the object or the location to which it is applied.

In other words, the advertisement commercial is used for indoor or outdoor use, color or dual color is mainly used, and the stadium is applied to main stadium, racetrack, soccer field, baseball field or swimming pool and the multi-purpose is for conference hall, small theater, And traffic signal is used for railway, which has a platform, ticket gate, waiting room, a passage, etc., and road including a city road, a highway or an induction lamp.

Also, the latest news from the stock market, stock market, stock market, airport for the arrival or departure, environmental information for environmental pollution, factories, office, And for information and messages used for publicity and information transmission by governments and local governments.

Such a display board can be classified into a mobile type that can be mounted on a truck or a container for various events, and a block type that can be used as a substitute for a show or a multi-cube.

Most electronic application display system companies use industrial computers or industrial embedded systems to implement high resolution LED display devices, PDP, and LCD display devices. When implementing small LED display devices, LED display devices are implemented using microcomputer boards have.

When an LED display device is implemented using an industrial computer, a signal is used from a VGA card or a DVI card of a computer, so a digital signal is converted into an LED signal through an image conversion device.

On the other hand, the importance of the electric signboard which does not cause malfunction in such electric signboards is emerging, and it is important to minimize the fault sites even when the breakdowns occur.

Conventionally, a conventional electric billboard system has a structure in which a plurality of electric billboard controllers for individually controlling a plurality of electric billboards are connected to one main controller.

However, in the related art, when one main controller is used, the display of the electric signboard is interrupted when an error occurs in the main controller.

In addition, even when a plurality of main controllers are used, there is a problem that signals supplied from all the main controllers are interrupted when spatial failures occur because they are arranged at the same positions spatially.

In addition, when a failure occurs in a sub-controller, a signal is not supplied to a sub-controller at a position where a failure occurs, and thus a display board located at a lower end can not be displayed.
