Accompanying drawing explanation
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model;
Fig. 3 is the schematic diagram of wireless receiving module warning circuit of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As shown in Figure 1, a kind of infrared emission warning device of the present utility model, include infrared emission signal acquisition circuit, trigger circuit, comparator circuit, radio emitting modular circuit and wireless receiving module warning circuit, the output signal of described infrared emission signal acquisition circuit is transferred to comparator circuit through trigger circuit, the output signal of described comparator circuit is sent to radio emitting modular circuit, and the output signal of described radio emitting modular circuit is sent to wireless receiving module warning circuit.
As shown in Figure 2, described infrared emission signal acquisition circuit consists of infrared light emitting diode VL and the photistor VT1 that forms correlation with it, base integration module U1 when described trigger circuit adopt NE555, after switching on power, the 6th pin outputting oscillation signal of base integration module U1 during NE555, this signal, after triode Q1 amplifies, drives infrared light emitting diode VL to the infrared light beam of spatial emission certain distance.While having unauthorized person invasion when whether (clear is surveyed in the place ahead of photistor VT1), photistor VT1 does not receive reflected signal, the 8th pin output low level of base integration module U1 during NE555, this signal is input to triode Q1 base stage, triode Q1 is because base stage is without bias voltage, in cut-off state, the collector output high level signal of triode Q1, this signal is input to the 3rd pin of voltage comparator U2, Yin Qi 2 pin current potentials are lower than U2 the 3rd pin current potential, therefore voltage comparator U2 output terminal is electronegative potential, FDD-5 transmitter module U3 Triggerless, do not send warning.
When having illegal invasion, the infrared light beam of infrared light emitting diode VL transmitting will be reflected by human body, make photistor VT1 receive infrared signal, the infrared signal that photistor VT1 receives is when NE555 after base integration module U1 inter-process, while making NE555, the 8th pin of base integration module U1 becomes high level from low level, this signal is input to triode Q1 base stage, the base stage of triode Q1 has bias voltage, triode Q1 is in conducting state, its collector output low level signal, this signal is input to the 2nd pin of voltage comparator U2, the 2nd pin current potential of voltage comparator U2 is higher than its 3rd pin current potential, the upset of voltage comparator U2 internal comparator inside circuit, be high level output, for FDD-5 transmitter module, U3 provides trigger pip, the modulation signal input end CP of FDD-5 transmitter module U3, high-frequency signal to transmitting is modulated, the antenna TX that FDD-5 transmitter module U3 output terminal connects externally launches modulated frequency electromagnetic waves.
As shown in Figure 3, LED 1 and loudspeaker Y that described wireless receiving module warning circuit is connected by JDD-5 receiver module U4 and output terminal thereof form, when JDD-5 receiver module U4 receives FDD-5 transmitter module U3 transmission electromagnetic wave signal, JDD-5 receiver module U4 the 4th pin audio signal output end CPA directly drive loudspeaker Y to send chimes of doom, its the 2nd pin data output end output low level makes LED 1 obtain electroluminescence simultaneously, represent to receive the alerting signal of extension set, remind staff on duty to go to site disposal, there is reliability strong, rate of false alarm is low, the advantages such as modular design, be widely used in finance, shop, the occasions such as factory.
Above-described is only a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
