Abstract

The utility model relates to an infrared multifunctional remote control receiver which is composed of an infrared receiving module, a time delay anti-jamming circuit, an IC1 circuit, a bistable locking and storing circuit and a drive circuit, wherein, one end of the infrared receiving module is connected to the ground, and the output end is connected with the time delay anti-jamming circuit to make signals which receive pulses transmitted to the time delay anti-jamming circuit; one end of the time delay anti-jamming circuit is connected with the infrared receiving module, and the other end is connected with the input end of the IC1 circuit; the input and the output of the IC1 circuit are connected with the time delay anti-jamming circuit, and the other end is connected with the bistable locking and storing circuit; the other end of the bistable locking and storing circuit is connected with the drive circuit. The remote controller receives emitted instructions and signals to carry out anti-jamming treatment. Then, the instructions and the signals are reshaped for bistable locking and storing and driving enforcement so as to complete the control function. The utility model uses an infrared signal of an infrared remote control emitter of the existing electric appliance as a signal to drive a receiver to work, cancels the control of a special remote controller, reduces the cost of a remote control device, reduces the amount of household controllers, and provides convenience for life.

Description

Infrared ray multifunction remote-control receiver

Technical field:

This utility model is to the improvement of existing radio remote control switch, has invented a kind of infrared ray multifunction remote-control receiver, belongs to the radio remote control switch technical field of structures.

Background technology:

Two kinds of traditional mechanical switch and radio remote control switchs.Traditional mechanical switch wiring trouble, inconvenient operation, rapid wear; Traditional wireless remote controller comprises transmitter and receiver two parts, and its receiver is subject to single, special-purpose transmitter control, does not have versatility, and complex structure, and production cost is higher, and misoperation is more, has influenced it and has promoted the use of.

Summary of the invention:

The utility model discloses a kind of infrared ray multifunction remote-control receiver, has overcome existing machinery switching manipulation inconvenience, rapid wear, and radio remote control switch is subject to shortcomings such as the restriction, cost height of single remote control transmitter.

Technical solution of the present utility model is as follows:

This infrared ray multifunction remote-control receiver is fast by infrared receiving, delay anti-jamming circuit, shaping amplification, IC1 circuit, bistable latch cicuit and driving circuit constitute, wherein, infrared receiving module is used to receive the frequency signal of the 38KHZ value of various household electrical appliances infrared remote controllers emissions, it is one three end-receiver part, one is that power end, an end are that ground, an end are that output links to each other with delay anti-jamming circuit, and the signal that receives pulse is sent to delay anti-jamming circuit; Delay anti-jamming circuit is made up of resistance, electric capacity, this signal is sent into triode amplify, and its end links to each other with infrared receiving module, and an end links to each other with the input end of IC1; The end of IC1 is that power supply, an end ground connection, end input, end output link to each other with delay anti-jamming circuit, and an end links to each other with the bistable latch cicuit; One end of bistable latch cicuit links to each other with IC1, and an end links to each other with driving circuit.

When general household electrical appliances infrared remote-control emitter sends command signal, the instruction signaling that infrared ray multifunction remote-control receiver will send receives, and carries out anti-interference process, shaping then, and the program light modulation, bistable is latched, and carries out to drive, and finishes control function.

Good effect of the present utility model is: utilize the infrared signal of existing household electrical appliances infrared remote-control emitter to drive receiver operation as signal, cancelled dedicated remote control control, reduced the cost of telechiric device, reduced the quantity of family expenses controllers, avoided the misoperation of controller, have easy to use, easy for installation, exempt from the wiring, can receive the instruction that family's various electrical equipment Infrared remote controller any key sends, for life is provided convenience.

Description of drawings:

Fig. 1 is the utility model circuit theory diagrams.

Embodiment:

According to shown in Figure 1, infrared receiving module H is three end-receiver parts, one termination powers, an end ground connection, and the other end links to each other with delay anti-jamming circuit with output, and the signal that receives pulse is sent to delay anti-jamming circuit; Delay anti-jamming circuit is made up of resistance R 1, capacitor C 1, this signal is sent into triode BG1 carry out the shaping amplification, and its end links to each other with infrared receiving module H, and an end links to each other with the input end CP of IC1; The termination power of IC1, an end ground connection, its input, output terminal CP link to each other with delay anti-jamming circuit, and the Q1 end links to each other with the bistable latch cicuit; The output terminal end of bistable latch cicuit links to each other with the input end of driving circuit, and driving circuit comprises that driving amplifier that resistance R 3, triode BG2 constitute succeeds the control end of electrical equipment J, finishes reception control action of the present utility model.

Receiver receives the frequency signal of the 38KHZ value that the infrared remote-control emitter of various household electrical appliances sends, receiver produces a undersuing and sends into anti-interference process, then this signal is sent into to become after the delay process and entered shaping after the long pulse and amplify, signal after shaping amplifier amplifies shaping is sent into bistable and is latched, carry out driving then, control various electrical equipment and open and close.
