Abstract

The utility model discloses an infrared remote control light-emitting diode (LED) display device which comprises an embedded singlechip and an infrared emission module, wherein the embedded singlechip is connected with an infrared receiving module, a decoder module and a display module at the same time; the decoder module is additionally connected with the display module; and wireless remote control connection is realized between the infrared receiving module and the infrared emission module by an infrared signal. As the control technology combining the HS0038 type infrared pulse receiving module and the AT89S51 type embedded singlechip is selected for use, the function of utilizing infrared rays to control an LED display screen to display specific pictures or characters can be realized by the infrared remote control LED display device.

Description

The Infrared Remote Control LED display device

Technical field

The utility model belongs to electronic technology field, relates to a kind of Infrared Remote Control LED display device.

Background technology

LED display is made up of the LED dot matrix, can come display text, picture, animation, video by the light on and off of redness or green light pearl, and content can be changed at any time, and the each several part assembly all is the display device of modular construction.Usually form by display module, control system and power-supply system.The dot matrix that display module is made up of the LED lamp constitutes, and is responsible for luminous demonstration; Control system can allow contents such as screen displaying character, picture, video by the light on and off of control respective regions, and it mainly is playing animation that perseverance is waved card; Power-supply system is responsible for transferring input voltage and input current to display screen required voltage electric current.

LED display not only can be used for indoor environment can also be used for outdoor environment, and has projector, video wall, the incomparable advantage of LCDs, has especially played increasing effect in the propaganda of business activity.

Yet existing LED display all is to rely on computer to carry out the transmission of view data as control system, thereby shows plurality of picture and Word message.Sometimes when people need change some view data then and there, then need the people of short notice control LED display to utilize computer to carry out the replacing of view data, to increase the workload of businessman like this, most important thing may delay the best propaganda time, the passive not interested content of possibility oneself of accepting of client, will reduce consumption interest, influence the distribution of businessman.

Summary of the invention

The purpose of this utility model provides a kind of Infrared Remote Control LED display device, solve the screen content that exists in the prior art and change the process complexity, the problem that the replacing time is long, the content that can also allow client control LED display voluntarily shows, increases the desire of its shopping.

The technical scheme that the utility model adopted is, a kind of Infrared Remote Control LED display device, comprise embedded scm and infrared transmission module, embedded scm is connected simultaneously with infrared receiving module, decoder module, display module, decoder module is connected with display module in addition, and infrared receiving module realizes that by infrared signal wireless remote control is connected with infrared transmission module.

The beneficial effects of the utility model are simple to operate, can allow client at the scene as seeing TV, utilize infrared remote control to select own interested commercial promotions information to show rapidly, have increased consumer's self initiative; And, help businessman to judge client's consumption orientation, additional income by the selected frequency of client for the LED content.

Description of drawings

Fig. 1 is the structured flowchart of the utility model device.

Among the figure, 1. infrared transmission module, 2. infrared receiving module, 3. embedded scm, 4. decoder module, 5. display module.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, the structure of the utility model device is, comprise embedded scm 3 and infrared transmission module 1, embedded scm 3 is connected simultaneously with infrared receiving module 2, decoder module 4, display module 5, decoder module 4 is connected with display module 5 in addition, and infrared receiving module 2 realizes that by wireless remote control signal is connected with infrared transmission module 1.

In the minimum control system that embedded scm 3 selects for use the AT89S52 single-chip microcomputer to be constituted, embedded scm 3 and circuit that miscellaneous part is connected, P3.2 is that the signal input of the external interrupt of 51 single-chip microcomputers connects infrared receiving terminal.By this stitch the infrared pulse that infrared receiving terminal received is conveyed into single-chip microcomputer; 74HC154 is a kind of 4 lines, 16 line code translators, and Y0 ~ Y15 wherein is the data input pin of code translator, and G1 is that the permission input position of code translator (when its high level, allows code translator to receive the data of single-chip microcomputer; When it is low level, the data that before received are preserved), it is connected by Single-chip Controlling with P1.0; G2 is the GND end; P0, P1 is connected with Y1 ~ Y15, as the Data Source of code translator; A, B, C, the D end is the light on and off that are used to control LED display full line lamp; So by G1, A, B, C, the circulation setting of D reaches the purpose of dynamic scan LED screen, to realize the demonstration of LED screen for picture, literal.

Display module 5 is translated yard device ﹑ 200 an Europe electricity resistance ﹑ triode 8050 by 4 8x8 point battle array ﹑ 4 lines 16 lines and is formed the 16x16 dot matrix jointly, and wherein code translator plays the effect of expansion I/O, and resistance and triode play the effect of up-flow.When the logical power supply of going up, press down infrared transmission module 1(telepilot) on ﹠ off switch after, receive infrared pulse by infrared receiving module 2, and it is passed to embedded scm 1, embedded scm 1 sends instruction by being provided with of program to LED display module 5 and finishes corresponding demonstration and blocked operation.

Be based on for infrared decoding program that infrared emission principle writes.Infrared pulse is to form by high level different in size, and the register 1,0 of appointment judged and give by single-chip microcomputer by the duration of detecting high level; The program that the comparison single-chip microcomputer is decoded in program afterwards realizes that different code values show the ability of different images data.

Existing LED display is reequiped, increase the LED display that infrared transmission module and infrared receiving module can repack it into a kind of Long-distance Control; By the button of touching telepilot, make infrared launcher emission infrared pulse, allow the device of control LED display carry out pulse decoding, just as selecting TV programme to select specific LED content, have significant advantage for scene propaganda popularization.
