Description

Infrared remote-controlled multi-purpose multiple-way switch

The utility model relates to a kind of indoor infrared remote controller that is used for; Especially a kind of remote control multi-path switching device.

The used device power supply (DPS) switch overwhelming majority of China's family's electrical appliance and industrial department adopts the contact switches at present, this switch is comparatively fixing owing to pressing holding position, use also more convenient, so use comparatively general, but because the randomness in using is restricted, this type of switch of place that is easy to generate spark such as oil, colliery in use, obviously be unfavorable, this class contact switch, cause spark to cause explosion accident easily, also need arrange lead if use in dwelling house, all be cumbersome thing; A kind of remote control multi-path switch that can be used for indoor and outdoor can also once occur on market by the electric device of remote control in coverage, but this type of installs mostly complex circuit, and directivity is relatively poor, and price is more expensive, the applicable performance instability has been subjected to certain restriction in use.

The purpose of this utility model is in order to develop infra-red remote control multi-channel switching device a kind of simple in structure, cheap by the improvement of structure.

The utility model is achieved in that

The utility model by infrared transmitter, infrared ray receive the control switch circuit, and shell form.

The operation principle of infrared transmitter is:

This circuit adopts LC-219 integrated circuit piece, and this integrated package is mainly used in encodes by certain frequency to switching pulse signal.When the input of signal by (4), (5) of integrated package LC-219, (6), (8), (9), (10) on ﹠ off switch, (13) Duan output, amplify through transistor T again and drive infrared emission tube RD emission infrared ray, send pulse train with this infrared emission tube RD, finish all processes of radiating circuit by certain frequency.Because radiating circuit LC-219 integrated package has adopted 3 volts of DC power supply, quiescent current is very little, and special two ends at battery are inserted a capacitor C 5 and charged normal for the LC-219 integrated package.For preventing misoperation, the end at power supply adds a K switch 7 again, like this, and the power consumption of all right conserve batteries.In order to avoid the frequency influence of remote controller, adopted the carrier frequency oscillation way in the circuit, it is to be determined by R2, the C4 of (11) end and R1, C2.Drive the outside radiated infrared light pulse of transmitting tube RD because switching pulse signal amplifies by triode T, therefore no matter can finish circuit pulse coding and carrier frequency oscillation action by that on ﹠ off switch.

Infrared ray receives the control switch circuit theory:

This circuit adopts special-purpose integrated package KA2184 of infrared ray and pulse decoding integrated package LC-220, as receiving tube RD ₂After receiving the carrier frequency oscillation electric pulse code signal that reflector sends, after C1 filtering is handled to (1) end input of integrated package KA2184, signal is from the output of (7) end, enter (1) end of integrated package LC-220 again, signal process integrated package LC-220 is cushioned behind the inside, divides six the tunnel after the decoding processing, by (6), (8), (9), (10), (11), the output of (12) end, every road is corresponding with the button on the radiating circuit, and signal amplifies, the decoding purpose thereby reach.

In order to realize shaking control at diverse location, can place infrared receiver tube in different places, simultaneously, circuit is connected in parallel on the infrared receiver tube RD2.In order under dark situations, to demonstrate the position of receiving tube RD2, in circuit, set up the compensatory light of RD again.The variable resistor R5 of (5) end output by adjusting integrated package KA2184 makes identical the getting final product of carrier frequency of its receiving center frequency and radiating circuit, and hold through series resistance R1 and capacitor C 2 ground connection (2), so as to the multiplication factor of increase integrated package.(3) capacitor C 3 ground connection of end series connection are used for the filtering of integrated package.(6) termination one integrating capacitor C6 improves the charging ability of integrated package.The decoding function of integrated package LC-220 is to output to the signal of (1) holding by KA2184 integrated package (7) end to realize; (2) end of integrated package LC-220 can play the bandpass filtering effect with a capacitor C 5 ground connection, (13) end seals in a resistance R 7 and inserts power supply, integrated package can play self-locking action, output in (6), (8), (9), (10), (11), (12) seals in the R8-R13 of resistance respectively, and the signal of output carries out work by the two-way brake tube G1-G6 that each road current-limiting resistance R15-R20 controls each road after triode T1-T6 amplifies.In order to show the conduction on each road, the RD3-RD8 that connected in circuit indicates the conducting on each road, thereby realizes all processes of control switch.

In addition, in the compensatory light of setting up, series connection R2, R3 remain on about dog days for the current limliting voltage that makes light source RD1.In alternating current AC two ends, set up a bidirectional switch K and can realize manually and shake two kinds of functions of control.The secondary active power filtering of being made up of C7, R14, C8 and C4, R4, C7 aims to integrated package KA2184 and LC-220 pulse decoding integrated package power supply usefulness.

This device is (Fig. 4) in use, as long as power line is inserted AC terminal, press the different key of reflector (Fig. 3) and can launch infrared signal, after receiver is received infrared signal, infrared signal is handled, just can show the reflector button label of pressing, the binding post below this corresponding label just has power supply output, and this moment, electric equipment got final product work.

Concrete using method is: (Fig. 3)

1, at first load onto battery to reflector, turn on the power switch 5, press different keys 4 as required, at this moment, emission display lamp 2 flashes and illustrates that reflector is working properly.

2, receiver (Fig. 4) is fixed on the place of a no shield thing, 220 volts power supplys are inserted AC terminal.

3, the electric equipment of want remote control is recorded in binding post 10,11(Fig. 4 under the different labels) above.

4, reflector is aimed at receiver, press the button of different labels, receiver just has the work of corresponding digital label, and the electrical equipment that this moment, corresponding label was pressed down gets final product work, has so just finished all actions of remote control.

Advantage of the present utility model is simple in structure, explosion-proof occasion such as oil exploitation, the colliery etc. of being suitable for low cost, and this device can prevent that so unexpected electric spark from causing an explosion accident owing to adopt contactless electrically conducting manner.As can removing the trouble that house wiring brings from indoor installation, a machine is at hand, and therefore arbitrarily remote control, but the indoor attaching plug of locking also can be widely used among industry and the civilian department.
