Description

General infrared remote control switch

The utility model relates to a kind of noncontacting switch of ordinary appliances on/off.

Now commercially available mains switch is mechanical structure, uses manually control, and it is not removable to be fixed on certain position usually, and each open and close lamp all will be gone to by the switch, very inconvenience; Especially get up the late into the night, seek switch trouble especially in the dark.

The purpose of this utility model is to make a kind of electronic switch of available infra-red remote control, realizes the remote control control of electric light.

The utility model is achieved in that

The utility model is grouped into by power unit, infrared remote receiver TFK, signal processing part, wherein, power unit comprises resistance R 1, capacitor C 1, C2, C3, voltage stabilizing didoe D1, rectifier diode D2, capacitor C 1 is the high voltage bearing electric capacity of low capacity, can play the current limliting step-down to the 220V AC power, voltage stabilizing didoe D1, rectifier diode D2 carry out rectification, voltage stabilizing to AC power, capacitor C 2, C3 and inductance L constitute " Л " type filter circuit, thereby for circuit provides the galvanic current source, as accompanying drawing 1; Signal processing comprises CMOS integrated circuit double D trigger, resistance R 2, R3, R7, R8, R10, R11, capacitor C 5, C6, C7, diode D3, triode V1, thyristor V2, wherein double D trigger comprises a trigger and b trigger, C6 and R8, C5 and R7 are time delay discharge circuit, control S end, the R end of a trigger respectively; As accompanying drawing 2; The a trigger CP end of the output of infrared recipient TFK and double D trigger joins, when hot outer recipient TFK receives the high frequency-infrared signal, A point current potential shown in the accompanying drawing 2 changes low by height, because the time-delay of C6 and R8 discharge, it is low that the S terminal potential of a trigger does not change at once, although thereby the CP of a trigger end has high-frequency signal, the Q end of a trigger does not overturn; After infrared signal keeps a period of time, the C6 discharge off, it is low that the S terminal potential of a trigger changes, and the high-frequency signal on the CP end of a trigger makes Q end upset----current potential of a trigger change high by low, produces a rising edge pulse, the b trigger connects into T trigger form, its CP holds a rising edge pulse of every acceptance, and the b trigger just overturns once, and the output of Q end changes a current potential, thereby the break-make of the break-make of control triode V1 and final control thyristor V2 reaches switching purposes.After the infrared signal in the external world disappeared, it is high that the current potential that A is ordered changes, and the S end of a trigger also becomes high potential, and switching circuit is ready once more.Because extraneous infrared signal is a high-frequency signal, thereby the fluctuation of high-frequency signal might make the S end state labile when being transferred to the critical point of electronegative potential by high potential of a trigger, makes the repeatedly upset of Q end, produces two rising edge pulses, make the b trigger also overturn twice, switch control is invalid; The effect of C5 and R7 is exactly that the R terminal potential becomes high potential and keeps a period of time in the first upset of the Q of a trigger end, thereby guarantees that the output of Q end does not change during this period of time, avoids the influence of the voltage fluctuation of high-frequency signal to a trigger

One of the utility model scheme preferably is: the S end of b trigger joins with the delay circuit that resistance R 6, capacitor C 4 are formed; Resistance R 4 is in parallel with capacitor C 4 simultaneously; Like this, when this power on circuitry, the S of b trigger end is for high potential and keep a period of time, thereby guarantees Q end output high potential, thyristor V2 conducting, conducting when making the contactor energising; The effect of R4 is the electric weight that bleeds off as early as possible when down circuitry in the C4, and the S of b trigger end still is high potential when guaranteeing to switch on once more; The S of b trigger end is by capacitor C 8 ground connection, eliminating the influence of disturbing pulse to the S end, and holding circuit stable.As accompanying drawing 3.

One of the utility model scheme preferably is: power unit comprises resistance R 1, capacitor C 1, C2, C3, voltage stabilizing didoe D1, rectifier diode D2, and D5 is as accompanying drawing 4.

One of the utility model scheme preferably is: power unit comprises resistance R 1, capacitor C 1, C2, C3, voltage stabilizing didoe D1, rectifier diode D2, D5, D6, D7; Rectifying tube D2, D5, D6, D7 form a rectifier bridge, carry out full-wave rectification, as accompanying drawing 5.
