Abstract
The utility model belongs to a microcomputer controlled advertisement media. The single-row luminous diode array display device is composed of a single-row luminous diode array and a microcomputer control circuit, wherein, the single-row luminous diode array is formed by that a plurality of vertically-arranged monochromatic and polychromatic luminous diodes are arranged in definite interval from each other; each vertical row takes the flickering switching time of 64 times / second to 256 times / second to change the content of pixels. The display contents or data are provided by microcomputer programs. The utility model has the advantages that simple structure, small volume, is capable of observing advertisement contents on a moving train, and is suitable for being used on advertisement medias in a subway tunnel.
Description
It is the advertising device that shows with the light emitting diode that the utility model belongs to a kind of, is applicable in the high speed moving vehicle tunnel such as subway, constitutes the advertising media of issue image and character.
At present, in subway tunnel as the various giant-screens of advertising media, LED display, pictorial poster, the advertisement of various colours such as neon bulb, transmitting various information to people, this kind media structure is simple, makes easily, after the subway train moves, people can't see the advertising message of outside clearly, and function limitation very causes the purpose that does not reach advertising results.
For solving the deficiency of above advertising media structure, the purpose of this utility model provides a kind of single-row light emitting diode matrix display device of dynamic demonstration, connects with microcomputer, utilizes many perpendicular shape display boards to realize the purpose that dynamically shows.
The utility model structural design is achieved in that this display device is made up of single-row light emitting diode matrix and microcomputer control circuit, wherein single-row light emitting diode matrix is by the monochrome and the multi-color LED of a plurality of vertical arrangements, and with certain composition that is spaced, every perpendicular row are with 64 times/second, or change pixel content (as shown in Figure 1) to 256 times/second flicker exchange number of times, each row of diode array are welded on the printed circuit board (PCB) by monochrome or polychrome diode, the outside is added with cover plate, be fixed on the base together, and be installed in both sides in the subway tunnel with fixed support, draw with the microcomputer communication interface by cable below and connect; Microcomputer controlled electro route CPU (8031), memory under program (27256), data latches (74LS373), data memory (6116), shift register (74LS164), driver (74LS06) and corresponding light emitting diode are formed, (as shown in Figure 4) its connection be CPU output respectively with memory under program (27256), data latches (74LS373), data register (6116) by data bus, address bus connects, toggle switch SW
1SW
2Connect with the CPU input port, photoelectric tube OPT3 connects with fracture among the CPU by reverser 74SL04, CPU output terminal RXD, and TXD passes through photoelectrical coupler (OPT1 OPT2) and communication interface J respectively by driver (7406) (7407)
1Connect, the serial line interface of CPU (8031) connects with driver (74LS06) with shift register (73LS373) simultaneously, and the output terminal of driver (74LS06) realizes that to being connected in series light emitting diode in the middle of the power end separately the light emitting diode vertical bar shows.(as Fig. 2, shown in 3)
The advantage of the utility model: simple in structure, volume is little, can see ad content on the motion train, and easy to install, cost is low, is suitable for doing in the subway tunnel advertising media.
Detailed structure of the present utility model is provided by following examples and accompanying drawing
Fig. 1 is single-row light emitting diode matrix display device shape assumption diagram;
Fig. 2 is single-row light emitting diode matrix display device control electrical schematic diagram;
Fig. 3 is single-row light emitting diode matrix display device control electrical schematic diagram;
Fig. 4 is single-row light emitting diode matrix display device system controlled by computer electrical schematic diagram;
Its structure is by shown in Figure 1, and 1 is fixed mount, and 2 is the light emitting diode battle array, and 3 is cover plate, and 4 is slot, and 5 is the display board shell, and 6 is the signal cable line, connects with control circuit.Fig. 2,3,4 is microcomputer control circuit.This enforcement side CPU (8013) serial data output terminal and 6 shift registers (74LS164) join, and join by 6 data latchs (74LS373) and 6 drivers (74LS06), and each driver (74LS06) output connects 6 light emitting diodes.
Its principle of work: can make people be sitting in a kind of advertising medium-single-row light emitting diode battle array that to see on the subway train of high-speed cruising outside window, it adopts a monochrome or a multi-color LED of vertically arranging, rearrange at certain intervals each other, in conjunction with the chip microprocessor Communication Control, utilize people's visual persistence effect, making travels in the car holds and can see a static or mobile image frame by vehicle window.
This single-row light emitting diode battle array is distributed in the both sides, tunnel of parallel subway vehicle window, and put some row respectively according to the width of vehicle window, and change the content of pixel with 64 times/second to 256 times/second flicker exchange number of times, when having only train operation, just can see picture clearly, therefore, be very suitable for subway etc. and do advertising media in the vehicle tunnel of operation at a high speed.The electricity that photoelectrical coupler is used in the serial communication is isolated, photoelectric tube is monitored the present condition that of train vehicle window, before the subway train arrived, the tunnel was in dark state, and this moment, photoelectric tube was output as " 0 " state, single-row light emitting diode battle array is not glimmered, when train through out-of-date, the light directive photoelectric tube of vehicle window makes it be output as one state, single-row light emitting diode battle array begins flicker, and the speed of flicker is by train running speed and vehicle window brightness decision.
