Description
Technical field
The utility model relates to a kind of light-operated circuit, specifically is a kind of infrared induction and light-operated circuit.
Background technology
Infrared ray is a kind of electromagnetic wave, and the position in electromagnetic spectrum is to be in infrared end, and the scope of wavelength roughly is 0.76um-1000um.Theory analysis and experimental study show not only in the sunlight infrared ray is arranged, and any object, as long as temperature is higher than absolute zero, just at infrared radiation ceaselessly.Therefore; Infrared ray is prevalent in occurring in nature; Our human body also is a source of infrared radiation; It and indoor other background objects are not only different aspect infrared energy, and the ultrared peak wavelength of each autoradiolysis is also inequality, and the infrared ray peak wavelength of human body radiation is about the 10um place.
The optical system of infrared sensor can be with all concentrating on the infrared sensor after reflection or special lens transmission from the infrared energy of a plurality of directions, and like this, infrared sensor just can detect the variation of the interior radiation of the anti-norm space of some solids.When in taking precautions against the zone, not have mobile targets such as human body, at room temperature the energy of infrared radiation is all smaller owing to all background objects, and is stable basically, so can not trigger camera, promptly camera is not worked.When human body is walked about in search coverage; Will cause the variation of infrared energy; Infrared sensor converts the variation of the infrared emanation energy between moving human body that receives and the background object into the corresponding signal of telecommunication, after suitably handling, delivers to camera and carries out image taking.
The lighting device that many light-operated and infrared inductions all occurred at present both at home and abroad under the dark situation of light, has the people from then on to pass through; Infrared inductor is sensed the infrared ray that human body radiation goes out; The circuit turn-on lamp will be bright, and when the people leaves the induction range of infrared inductor, lantern festival is extinguished automatically.But the performance of this type of lighting device is all lower at present, and the susceptibility of infrared induction and light-operated circuit is not high, does not reach the effect of burglar alarm.
The utility model content
The utility model provides a kind of infrared induction and light-operated circuit, and the susceptibility that has solved infrared induction and light-operated circuit in the past is not high, does not reach the problem of burglar alarm effect.
The utility model is that the technical solution problem mainly realizes through following technical scheme: a kind of infrared induction and light-operated circuit; Comprise infrared sensor D and processor S; Said infrared sensor D comprises 3 pins; Processor S comprises 16 pins; The middle pin of infrared sensor D is connected with the 14th pin of processor S, and two other pin of infrared sensor D connects high level, low level respectively, is connected with capacitor C 3 and resistance R 4 between the middle pin of said infrared sensor D and the low level; Be connected with parallel resistor R3 and capacitor C 1 between the 12nd pin of said processor S and the 13rd pin, be connected with the resistance R 2 and capacitor C 2 of series connection between the 13rd pin of processor S and the 16th pin.
Be connected with resistance R 1 between the 9th pin of said processor S and the high level, be connected with resistance R 5 between the 9th pin of processor S and the low level.
Be connected with resistance R 6 between the 10th pin of said processor S and the low level.
Be connected with the resistance R 7 and capacitor C 4 of connecting between the 16th pin of said processor S and the low level.
The model of said processor S is BISS0001.BISS0001 is a sensing signal processor with superior performance, can open devices such as all kinds of incandescent lamps, fluorescent lamp, buzzer automatically fast.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model adopts BISS0001 as sensing signal processor; Transducer D reaches infrared signal the 14th pin of BISS0001; After processing and amplifying; BISS0001 output triggering signal deactivation delay circuit, the high-performance of BISS0001 makes entire circuit have higher sensitivity, can meet the requirement of burglar alarm fully.
