Description

The infrared ray multi-channel remote control switch

The utility model relates to a kind of infrared ray multi-channel remote control switch.

The infrared ray multi-channel remote control switch of known use, comprise infra-red code reflector and decoding infrared ray receiver, whenever by the button on the next reflector, just connect a way switch, after connecting variable connector, cut off each Switching Power Supply again as need, will repeat again to operate cumbersome by each button.

The purpose of this utility model is to overcome the above-mentioned deficiency of common infrared ray multi-channel remote control switch and provide a kind of simple to operation, can cut off the infrared ray multi-channel remote control switch of each road power supply simultaneously.

The utility model comprises infra-red code reflector and decoding infrared ray receiver, reflector is by key switch, DC power supply, triode BG7, formations such as transmitting tube D1 and inclined to one side code IC IC1, be provided with unit such as controlled oscillator and output driver in the circuit, the decoding receiver is by transformer KB, voltage stabilizing integrated 7808, the bridge rectifier that D1-4 forms, the filter circuit that C1-3 forms, preposition amplification circuit IC2, decoding integrated circuit IC3, triode DG1-5, formations such as relay J 1-5 and receiving tube D18, through transformation, rectification, filtered electric current one road is succeeded potential winding one end of electrical equipment J1-5, integrated 7808 backs of another Lu Zaijing voltage stabilizing are connected with decoding integrated circuit IC3 by preposition amplification circuit IC2, decoding integrated circuit IC3 is connected with relay J 1-5 by triode BG1-5, receiving tube D18 is connected with preposition amplification circuit IC2, be provided with band idle contact J61 between voltage stabilizing integrated 7808 and the preposition amplification circuit IC2 by relay J 6 controls, the connected mode of relay J 6 is identical with relay J 1-5, be potential winding one end and rectification, filter circuit is connected, and the other end is connected with decoding integrated circuit by triode BG6.Like this, after multiple power supplies connects, only need on reflector, to press and relay J 6 corresponding key switches, normally-closed contact J61 is disconnected, just can cut off each road power supply simultaneously by relay J 6.

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Fig. 1 is the electrical schematic diagram of the utility model middle infrared (Mid-IR) coded transmitter.

Fig. 2 is the electrical schematic diagram of the utility model middle infrared (Mid-IR) decoding receiver.

As shown in the figure, the utility model embodiment provides five road infrared telecontrol switchs, its infra-red code reflector is by key switch K1-6, DC power supply, triode BG7, formations such as transmitting tube D1 and the integrated circuit I G1 of coding, circuit inside is provided with unit such as controlled oscillator and output driver, as switch such as the K1 of pushing button, can be with 13 pin of VDD input coding integrated circuit (IC) 1, make the inner generation of IC1 coded pulse, regularly, modulating oscillation, controllable oscillatory, and, make its conducting through resistance R 2 trigger triode BG7 by the output of 1 pin, drive transmitting tube D1 and launch the infrared pulse string.The decoding infrared ray receiver is by transformer KB, voltage stabilizing integrated 7808, the bridge rectifier that D1-4 forms, the filter circuit that C1-3 forms, preposition amplification circuit IC2, decoding integrated circuit IC3, triode BG1-6, formations such as relay J 1-6 and receiving tube D18, the 220V civil power is 12V through the step-down of KB transformer, through the D1-4 bridge rectifier, one tunnel potential winding one end of directly sending into 12V relay J 1-6 behind the C1-3 capacitor filtering, another road is 8V by integrated 7808 voltage stabilizings of voltage stabilizing, send into preposition amplification circuit IC2 and decoding integrated circuit IC3 as working power by normally-closed contact J61 again by relay J 6 control, receiving tube D18 is connected with preposition amplification circuit, and relay J 1-6 is connected with decoding integrated circuit IC3 by triode BG1-6.After receiving by receiving tube D18 by the infrared pulse string of reflector emission, send into 1 pin of preposition amplification circuit IC2, through the inner amplification of IC2, amplitude limit, bandpass filtering, integration relatively back are failed 13 pin that line goes out to send into decoding integrated circuit IC3 by 7 pin, invade through IC3 inside and to dash, be divided into 6 the tunnel after the decoding, wherein one the tunnel with the corresponding output high level of coding and the self-locking of reflector generation, high level is by resistance such as R4 trigger triode BG1, make relay J 1 adhesive, connect first via electrical appliance power supply.When pressing the K6 key of reflector, 1 pin of decoding integrated circuit IC3 correspondence is exported high level equally, by resistance R 9 trigger triode BG6, and relay J 6 adhesives, normally-closed contact J61 disconnects, and makes IC2 and IC3 dead electricity, and 6 tunnel outputs all disconnect.In like manner, release again after the relay J 0 potential winding dead electricity and send out, force normally-closed contact J61 closed again, connect the 8V power supply of IC2 and IC3, for start is for the second time got ready.

The utility model is by above-mentioned concrete structure, following of the situation of connecting at multiple power supplies needs can disconnect all power supplys by next teleswitch, therefore easy to operate, simultaneously, the utility model during operation, if have a power failure suddenly, every the time when coming again, remote controller still is ready, i.e. electrical appliance power supply Close All state, like this, also just needn't worry to occur the people not the time electrical appliance in running order situation.
