Description
Technical field
The invention belongs to wireless remote control technology field, relate in particular to a kind of multiplex infrared telechirics.
Background technology
Along with development in science and technology, people's electronic equipment is by the side of more and more, electricly joins a telepilot by one, and the telepilot of average family is all more than 3.And incompatible between telepilot, time used in everyday, need to look for the telepilot that equipment is corresponding, for the modern who day by day focuses on quality of the life, can more and more feel trouble.Along with being on the increase of electrical equipment, finding remote controller is intolerable thing especially.
From nineteen fifty-five TV remote controller invent so far, telecontrol engineering does not have breakthrough development, still uses now the infrared technique that the 1980's extensively adopted.Samsung is once in 2006, for its plasma TV product has configured page turning telepilot, and the control of built-in television machine, DVD, but do not possess programing function; And universal remote control and study remote controller on current market, although infrared coding technology comparative maturity, because deviser is not comprehensive to the investigation of user's request, not have to release the product of identical customer demand.Along with the development of the mechanics of communication such as network and bluetooth, most manufacturers has been released Smart Home product, and for most average family, Smart Home is also remoter, builds and the excessive biggest obstacle that becomes Smart Home popularization of later maintenance cost.Therefore domestic users, what need is that price is low, function is simple and practical, the reliable remote control solution of technology.
Current various brand, the telepilot of various device, incompatible each other, the product of even same manufacturer different times, the control chip of employing is different with control protocol, and telepilot is incompatible.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of by the multiplex infrared telechirics of RFID client perception and guest room information.
The technical solution adopted for the present invention to solve the technical problems is: multiplex infrared telechirics, comprise single-chip microcomputer and connected computer-aided infrared decoding scrambler, described computer-aided infrared decoding scrambler comprises there is infrared remote control chip, and described infrared remote control chip is for decoding the infrared signal receiving and store.
As the further optimization of technique scheme, described single-chip microcomputer is also connected with programmable controller, and described programmable controller is realized reading and editing outside infrared control signal.
As the further optimization of technique scheme, described single-chip microcomputer is also connected with LCDs, and LCDs is for display interface and show the information of editing.
As the further optimization of technique scheme, described single-chip microcomputer is connected with main control computing machine by PC serial ports.
In single-chip microcomputer infrared control technology, after the employing single-chip microcomputer of novelty is analyzed key commands, then infraluminescence chip is sent to instruction, finally send infrared signal.
Be different from fool's mode of learning of traditional universal remote control, in Programmable control technology, the program that control protocol code is write direct of novelty, then be synchronized in equipment by serial ports.
This project is different from common Smart Home and full-function remote-control device product, reduced when causing cost, also refine have for use function.Compared with traditional product, in cost and application, more have superiority.
The beneficial effect main manifestations of the multiplex infrared telechirics of the present invention is: use simply, easy to operate, can control the televisor in guest room, Set Top Box, air-conditioning, multimedia recreation and guest room are electric etc.
Brief description of the drawings
Fig. 1 is the frame structure schematic diagram of the multiplex infrared telechirics of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the invention is described:
As shown in Figure 1, as the preferred forms of the multiplex infrared telechirics of the present invention, it comprises single-chip microcomputer and connected computer-aided infrared decoding scrambler, described computer-aided infrared decoding scrambler comprises there is infrared remote control chip, and described infrared remote control chip is for decoding the infrared signal receiving and store.
Described single-chip microcomputer is also connected with programmable controller, and described programmable controller is realized reading and editing outside infrared control signal.
Described single-chip microcomputer is also connected with LCDs, and LCDs is for display interface and show the information of editing.
Described single-chip microcomputer is connected with main control computing machine by PC serial ports.
Infrared remote control chip technology and coding protocol analysis, taking the current application infrared transmitting circuit that the UPD612G chip of the most Japanese NEC forms as example, its taking pulsewidth as 0.565ms, interval 0.56ms, cycle represent " 0 " as the combination of 1.125ms, taking pulsewidth as 0.565ms, interval 1.685ms, cycle be as the combination of 2.25ms represents " 1 ", forms 32 bit serial binary codes with this.This type of binary coding, conventionally based on Philip RC-5 agreement, adopts computer-aided decoding to improve the accuracy of study.
The software and hardware condition of single-chip microcomputer and computer-aided infrared decoding coding, telepilot mode of learning is divided two kinds, and one is the built-in single-chip microcomputer of telepilot, by infrared receiving chip, directly the infrared signal receiving is decoded and is stored; Another kind is that computer expert crosses external special infrared equipment, infrared signal is decoded, and signal is carried out to analyzing and processing.
Liquid crystal display display technique, the equipment that air-conditioning etc. is possessed to state parameter is controlled, and adopts little liquid crystal display to show current control model and opertaing device parameter.
Control software development able to programme, realizes reading and editing, the selection of telepilot control model, liquid crystal display display interface and demonstration information editing, the definition of the each function key of telepilot outside infrared control signal.
PC Serial Communication, this technology is that this project is different from the most directly embodying of conventional universal remote control, by synchronizeing with PC, can in fetch equipment, arrange, and also the control program editting can be downloaded into new equipment, is convenient to batch working.
By reference to the accompanying drawings the preferred embodiment for the present invention is explained in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
Do not depart from the spirit and scope of the present invention and can make many other changes and remodeling.Should be appreciated that and the invention is not restricted to specific embodiment, scope of the present invention is defined by the following claims.
