Description

A kind of radio transmitting device of infrared remote control switch

Technical field

The utility model relates to a kind of radio transmitting device, particularly be a kind of radio transmitting device of infrared remote control switch.

Background technology

Infrared or light-operated circuit is used more extensive, is mainly used in the electric consumption on lighting switchgear, but owing to there is not wireless launcher, the illumination that can not remote monitoring is light-operated or infrared circuit is controlled or the state of consumer.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of radio transmitting device of infrared remote control switch is provided.

The utility model solves the technical scheme that its technical matters adopted: a kind of radio transmitting device of infrared remote control switch; Comprise infrared transmitter, Rcv decoder, light-operated switch module and power switch module; The output signal of said infrared transmitter is sent to Rcv decoder, and the output signal of said Rcv decoder transfers to controllable silicon trigger module, wireless transmitter module and indicating module through light-operated switch module, power switch module controls successively.

Further, said infrared transmitter is made up of multivibrator, driving stage VT1 and the infrarede emitting diode VD5 that the CD4011 42 input end Sheffer stroke gate CMOS chip IC 1 that connect successively constitute.

Further, said Rcv decoder is made up of the infrared photodiode VD6, operational amplifier IC2, the LM567 supersonic frequency (s.f.) code translator IC3 that connect successively.

Further, said light-operated switch module is made up of the photoresistance RL and the potentiometer RP3 of triode VT3 and input end parallel connection thereof.

Further, said power switch module adopts TWH8778 power switch pipe IC4.

Further, said wireless transmitter module adopts FDD-5 wireless transmitter module U1.

Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: the illumination that wireless remote monitering is light-operated or infrared circuit is controlled of the utility model ability or the state of consumer; Do not work the daytime in that natural light is arranged; Just work after having only at nightfall, can be used for occasions such as guard and alarm or illuminating lamp control.

Embodiment

Like Fig. 1, shown in Figure 2; The radio transmitting device of a kind of infrared remote control switch of the utility model; Comprise infrared transmitter 1, Rcv decoder 2, light-operated switch module 3 and power switch module 4; The output signal of said infrared transmitter 1 is sent to Rcv decoder 2, and the output signal of said Rcv decoder 2 is successively through light-operated switch module 3, power switch module 4 control transmission to controllable silicon trigger module 5, wireless transmitter module 6 and indicating module 7.

Said infrared transmitter 1 is made up of multivibrator, driving stage VT1 and the infrarede emitting diode VD5 that the CD4011 42 input end Sheffer stroke gate CMOS chip IC 1 that connect successively constitute; NAND gate circuit F1, F2 and resistance R 1, potentiometer RP1, capacitor C 2 by CD4011 42 input end Sheffer stroke gate CMOS chip IC 1 input end are formed the multivibrator about 40kHz; Oscillator signal is after NAND gate circuit F3, F4 shaping; Be connected to driving stage VT1; Drive infrarede emitting diode VD5 and send the infrared light pulse that receives the 40kHz modulation; Said Rcv decoder 2 is made up of the infrared photodiode VD6, operational amplifier IC2, the LM567 supersonic frequency (s.f.) code translator IC3 that connect successively; Infrared photodiode VD6 is transformed into corresponding electric signal with infrared signal, and is connected to the proportional amplifier of being made up of operational amplifier IC2 and resistance R 6, R5 etc., is connected to the input end of LM567 supersonic frequency (s.f.) code translator IC3 then; The potentiometer RP2 of LM567 supersonic frequency (s.f.) code translator IC3 is tuned on the carrier frequency (about 40kHz) of infrared transmitter its centre frequency fo ≈ 1/ (1.1RP2C4), makes decoding sensitivity the highest.

When infrared sending and receiving part operate as normal, if there is the people to rush its security area of people, human body is returned infrared reflection; After infrared photodiode VD6 received, LM567 supersonic frequency (s.f.) code translator IC3 just solved the 40kHz signal, and exports a negative skip signal at its output terminal; Cause triode VT2 to end, capacitor C 7 is through resistance R 9, diode VD7 charging, after the current potential of the 5th pin control end of TWH8778 power switch pipe IC4 reaches 1.6V; The TWH8778 power switch pipe IC4 conducting that is triggered through resistance R 11 current limlitings, divides three tunnel outputs; First via output makes the controllable silicon SCR triggering and conducting, because of the controllable silicon SCR conducting, connects consumer; The second tunnel output is through resistance R 12 current limlitings, and it is luminous that LED 1 is lighted; Third Road output is through resistance R 13 current limlitings; Make FDD-5 wireless transmitter module U1 obtain trigger pip; The 2nd pin trigger end by FDD-5 wireless transmitter module U1 also is high level state; FDD-5 wireless transmitter module U1 home block is sent switching signal to receiver module, reaches long-range understanding consumer and is switched on or switched off the power supply situation.

Said light-operated switch module 3 is made up of the photoresistance RL and the potentiometer RP3 of triode VT3 and input end parallel connection thereof; Daytime; Photoresistance RL is low resistive state because of receiving illumination; Triode VT3 saturation conduction, its collector is electronegative potential, with the control utmost point clamper of TWH8778 power switch pipe IC4 below 0.6V.Therefore; TWH8778 power switch pipe IC4 always is in cut-off state in the time of daytime, and infrared facility is inoperative, to night; Photoresistance RL is high resistant; Triode VT3 ends, and the conducting of TWH8778 power switch pipe IC4 and by just no longer controlled by triode VT3 realizes daytime and opens or closes the effect of electric consumption on lighting equipment night automatically.

An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
