Because the present invention has adopted above technical scheme, can find out suitable simple of its structure, components and parts are few, with low cost.
Accompanying drawing explanation
Fig. 1 is the physical circuit figure of invention.In figure, 1 is that telechiric device, 2 is that remote signal receiving circuit, 3 is infrared emission warning device.
Embodiment
A kind of plain type Radio infrared correlation warning device, is characterized in that: comprise telechiric device, remote signal receiving circuit and infrared emission warning device;
Telechiric device: be HF-15 infrared transmission module, comprise HF-15 chip, 5 pins and 6 pins of HF-15 chip connect power supply by switch S K, and 3 pins and 4 pins connect the light emitting diode that model is PH303, and 1 pin is connected by potentiometer RP1 with 2 pins;
Remote signal receiving circuit: comprise HJ-15 chip, 1 pin of HJ-15 chip and 2 pins connect the infrared receiving tube of PH302,3 pins of HJ-15 chip and the indirect relay K of 6 pins, relay K is as the power switch of infrared emission warning device;
Infrared emission warning device, it comprises warning main circuit and control circuit, described warning main circuit comprises that alarm bell and relay K A often start closed contact, described alarm bell often starts closed contact access electrical network by relay K A, described control circuit comprises, infrarede emitting diode, infrared phototriode VT1, adjustable resistance RP1-RP3, resistance R 1-R8, triode VT2-VT5, filter capacitor C, relay K A, diode VD, described infrarede emitting diode, R1, after adjustable resistance RP1 series connection, connect power positive cathode, described infrared phototriode VT1 collector meets adjustable resistance RP2, infrared phototriode VT1 emitter is by resistance R 2 ground connection, infrared phototriode VT1 base stage connects the base stage of triode VT2, the collector of triode VT2 meets R3, the grounded emitter of triode VT2, the base stage of triode VT3 connects the collector of triode VT2, the collector connecting resistance R4 of triode VT3, the emitter of triode VT3 is by R5 ground connection, the base stage of triode VT4 connects the emitter of triode VT3, triode VT4 provides collector voltage by electronics R7, the emitter of triode VT4 meets adjustable rheostat RP3, the grounded emitter of triode VT5, triode VT5 connects the collector of triode VT4 by resistance R 8, described relay K A one end is connected with the collector of triode VT5, another termination power, relay K A two ends are provided with fly-wheel diode VD.
The present invention realizes the induction of circuit to human body or object.The function of infra-red alarm circuit is that to utilize light activated element to connect its function of infrared transmitter be to utilize the pulse of infrared light-emitting diode utilizing emitted light, thereby the light pulse that transmitting-receiving shoots out, and light pulse signal is converted into electric signal, it is amplified simultaneously.First switch on power, infrarede emitting diode VL sends infrared light, receive a branch of infrared light, and be translated into the signal voltage of same frequency, after infrared ray full range amplifying circuit amplifies, sending into phototriode VT1 receives after infrared light, its internal resistance decline (conducting), triode VT2 obtains base bias and conducting, VT3(notes positive-negative-positive pipe) obtain base stage negative bias and conducting, VT4 is by the collection of resistance R 4 and VT3---and emitter-base bandgap grading internal resistance obtains base bias and conducting, VT5 due to base stage just and bias voltage is too small ends, relay K A is in release conditions, it is often opened to get an electric shock and disconnects, alarm bell HA does not ring.After infrared light is blocked by human body, in phototriode VT1, resistive is very large, triode VT2, VT3, VT4 cut-off, and VT5 conducting, relay K A adhesive, it often opens the closure of getting an electric shock, and electric bell HA sends chimes of doom.
