Compared with prior art, the beneficial effects of the utility model are: owing to adopting above-mentioned structural design, namely by three inhomogeneous sensors, perception judging whether can have people Yin Gaowen or anoxic in car and produce danger, automatic alarm also externally sends calling for help simultaneously, thus the infant in stranded car is succoured in time.
Accompanying drawing explanation
Accompanying drawing 1 is the principle schematic of the utility model one embodiment.
In figure, each label respectively: (10) temperature controller, (20) oxygen sensor, (30) thermal infrared human inductor, (40) phonetic alarm, (50) loudspeaker.
Embodiment
Provide an embodiment below in conjunction with accompanying drawing to be described in further detail the utility model:
Please refer to Fig. 1, a kind of infant of the utility model misses automatic alarm call-for-help device in car locking, comprise PNP type triode Q1, NPN type triode Q2, Q3, Q4, temperature controller 10, oxygen sensor 20, thermal infrared human inductor 30, phonetic alarm 40 and loudspeaker 50, the emitter of described PNP type triode Q1 connects automobile storage battery positive pole through a resistance R1, base stage connects automobile storage battery negative pole through a resistance R2, be serially connected with a resistance R3 between emitter and base stage, base stage is through a resistance R4 ground connection; The collector of described PNP type triode Q1 connects one end of temperature controller 10, oxygen sensor 20, thermal infrared human inductor 30 respectively; The other end of described temperature controller 10, oxygen sensor 20, thermal infrared human inductor 30 connects base stage, the base stage of NPN type triode Q3, the base stage of NPN type triode Q4 of NPN type triode Q2 respectively; The first sample circuit is provided with between described temperature controller 10 and NPN type triode Q2, described first sample circuit comprises resistance R5, R6, R7, temperature controller 10 is connect, ground connection after the indirect resistance R7 of described resistance R5 and resistance R6 after the base stage series resistor R6 of described NPN type triode Q2 and resistance R5; The second sample circuit is provided with between described oxygen sensor 20 and NPN type triode Q3, described second sample circuit comprises resistance R8, R9, R10, oxygen sensor 20 is connect, ground connection after the indirect resistance R10 of described resistance R8 and resistance R9 after the base stage series resistor R9 of described NPN type triode Q3 and resistance R8; The 3rd sample circuit is provided with between described thermal infrared human inductor 30 and NPN type triode Q4, described 3rd sample circuit comprises resistance R11, R12, R13, thermal infrared human inductor 30 is connect, ground connection after the indirect resistance R13 of described resistance R11 and resistance R12 after the base stage series resistor R12 of described NPN type triode Q4 and resistance R11; The collector of described NPN type triode Q2, Q3 all meets power supply VCC, and emitter all connects the collector of NPN type triode Q4; The emitter serial connection phonetic alarm 40 of described NPN type triode Q4 and loudspeaker 50; Described phonetic alarm 40 connects the emitter of NPN type triode Q4 through a resistance R14.
During utility model works, when automobile is when flame-out, A point current potential declines, and PNP type triode Q1 starts working; When temperature controller 10 exceeds the temperature of setting, its output voltage makes NPN type triode Q2 start working through the first sample circuit, and C point current potential raises; Now, if thermal infrared human inductor 30 is responded to less than there being people, then D point no-voltage, NPN type triode Q4 can not work, and phonetic alarm 40 can not get control voltage, can not report to the police; If thermal infrared human inductor 30 has sensed people, the voltage that the 3rd sampling voltage obtains more than 0.5V has made NPN type triode Q4 start working, and phonetic alarm 40 obtains control voltage, and chimes of doom sounds; And oxygen sensor 20 as detect oxygen level lower than 18% time, the voltage that second sample circuit obtains more than 05V makes NPN type triode Q3 start working, if now thermal infrared human inductor 30 has sensed people, then NPN type triode Q4 starts working, phonetic alarm 40 obtains control voltage, and chimes of doom sounds.
In sum, whether the utility model is detected in car respectively by three sensors whether people, vehicle interior temperature be too high, whether oxygen concentration descends degradation information to judge whether have people in car and whether be in danger in car, and send dangerous situation in time and report to the police and call for help, thus avoid being caused danger event by the infant forgotten separately in car.
By reference to the accompanying drawings exemplary description is carried out to the utility model above; obvious realization of the present utility model is not subject to the restrictions described above; as long as have employed the various improvement that technical solutions of the utility model are carried out; or say that design of the present utility model and technical scheme are applied to other occasions, all in protection domain of the present utility model without improving.
