Embodiment Construction

[0020] Further explain in detail in conjunction with accompanying drawings;

[0021] Examples and related components are as follows: R is the resistance, C is the capacitance, E is the electrolytic capacitor, for the crystal oscillator, for light-emitting diodes, FV fuse for grounding, The positive stage of the power supply, J is the standard socket interface, L is the standard terminal block, DC is the power interface; IC is the chip, and PC is the single-chip microcomputer;

[0022] In the example, there are 16 sub-workstations parallel and independent in the sub-workstation, each sub-workstation is correspondingly connected to a group of display light columns, and there are 30 mutually parallel and independent display light columns 9, and each display light column 9 is a multi-single-chip microcomputer display structure system As shown in Figure 2, it is a two-level centralized network shape, with one upper node, the node has a communication interface 10 and ...

Abstract

Using microelectronic technique and TV principle, the invention solves following issues: synchronization between advertisement and running train, controlling gray scale and colors of image, stable reliable operation for long time, and easy to replace ad in time and editing content of ad. The equipment includes four parts: (1) through optical fiber interface, main computer system in main station is connected to network exchanger; (2) substation system composed of parallel independent sub workstations, each sub workstation possesses assistant computer system connected to up Ethernet interface, and down serial interface; (3) synchronization system composed of velometer and sync generator; (4) display system possesses parallel independent displaying light columns in star structure system of multiple single chips. Features are: stable image plane, high brightness, high resolution and good colors.

Description

technical field [0001] The invention belongs to the field of advertising devices and relates to a tunnel advertising device. Background technique [0002] There are two types of existing tunnel advertising devices, one is the light box type, that is, light boxes are arranged in groups on the tunnel wall, and each light box has the same or different advertising patterns. The length of the second flashing time is pre-set according to the speed of the train, so that passengers sitting in a train running at a constant speed can see static or dynamic advertisements through the window glass. The disadvantages of this type of device are: The flash is not easy to control, so the image is not clear, and it is difficult to change the content of the advertisement. That is to say, once an advertisement is completed, it is difficult to change the content in a short time. The light box of the advertising pattern of the new content can be transformed, and its normal maintenance costs are ...
