Abstract
The utility model relates to a universal infrared remote control switch, comprising an infrared receiving / demodulation circuit, a bistable output circuit, and a relay control circuit. The utility model is characterized in that the infrared receiving / demodulation circuit is composed of a receiving module F and a triode T1 and is provided with an anti-interference circuit; the bistable output circuit is connected with a clear circuit. The utility model has no need of a coded identification circuit and a demoding circuit, can be directly used with the report controller of a domestic appliance, has the advantages of convenient use, reliable working, simple circuit, modularized appearance, low cost, etc., and is particularly suitable foe assembling with a wall switch socket.
Description
The utility model relates to a kind of infrared telecontrol switch, especially with the general infrared telecontrol switch of domestic electrical equipment remote controller.
The circuit structure complexity of the present infrared telecontrol switch that generally uses, volume is big, and cost is higher, about 180 yuan one of sale price, the user is difficult to accept, and especially needs the configure dedicated reflector, uses inconvenient.
The utility model purpose is to provide a kind of structure tube list, volume is little, cost is low, can with the general infrared telecontrol switch of household electrical appliance remote controller.
Technology contents of the present utility model in conjunction with the embodiments and accompanying drawing give to describe in detail.
Fig. 1 is the universal infrared telecontrol switch embodiment of a utility model circuit block diagram.
Fig. 2 is Fig. 1 embodiment electrical schematic diagram.
The utility model infrared telecontrol switch comprises electric primary circuit, infrared ray reception/demodulator circuit, bistable state output circuit, relay and control circuit thereof, it is characterized in that reception/demodulator circuit is by receiver module F and triode T
1Form, the signal output part of receiver module F meets triode T
1Input b, the output C of triode connects the input (3 pin) of bistable circuit IC, receiver module F converts infrared signal to electric pulse, with the output state of control bistable circuit IC, the F module has anti electromagnet interference function against sunshine, and volume is little, price is excellent, and present embodiment adopts F538.Receiver module F is connected to one by diode D
1And capacitor C
1The anti-clutter circuit of forming to prevent the interference of immediate current, guarantees that the operating state of F module is errorless, and F module and household electrical appliance remote controller are general.For improving triode T
1Functional reliability, present embodiment is at triode T
1Output C on be connected to by resistance R
1And capacitor C
2The anti-clutter circuit that is formed in parallel improves triode T
1Switch stability.Present embodiment bistable circuit IC has a clear circuit, and this clear circuit is by resistance R
3And capacitor C
3Form.This universal infrared telecontrol switch also is provided with a hand push button switch J
1, push-button switch J
1Be attempted by triode input b.
This universal remote control switch course of work is summarized as follows: when the F module receives the infrared pulse signal, this signal can be sent by the household appliance remote control reflector, and F module output becomes low level, triode T by the high level response
1Become by conducting and to end, input 3 pin of bistable circuit IC are high level, and the IC circuit state changes, the output high level, and relay and control circuit action thereof, the relay K adhesive, remote control switch is logical.Infrared signal of the every reception of F module, IC circuit output state changes once, thus control relay adhesive or disconnection reach on-off action.
This infrared telecontrol switch need not code identification, decoding circuit, and is easy to use, and reliable operation, and circuit is simple, the epimorph blocking, volume is little, price is low, outstanding suitablely use with the wall switch socket assembling.
