Description of drawings
Fig. 1 is the frame assumption diagram of the utility model;
Fig. 2 is the circuit theory diagrams of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
Like Fig. 1, shown in Figure 2; A kind of infrared switch control circuit of the utility model; Comprise body induction circuit 1, photoelectric isolating circuit 2, circuits for triggering 3, oscillating circuit 4, microprocessor control circuit 5 and load driving circuits 6; The output signal of said body induction circuit 1 transfers to microprocessor control circuit 5 through photoelectric isolating circuit 2, circuits for triggering 3, oscillating circuit 4 successively, and the output signal controlling of said microprocessor control circuit 5 is sent to load driving circuits 6.
The infrared signal that said body induction circuit 1 gives off through AMNI type sensor IC human body; The output of said AMNI type sensor IC is connected to the base stage of triode VT1; The collector electrode of triode VT1 is connected to and gate circuit F1; When AMNI type sensor IC detected the infrared signal that human body radiation goes out, its output Out was high level, this high level signal through triode VT1 amplify and gate circuit F1 anti-phase, shaping after; The interior light emitting diodes that drives photoelectrical coupler IC1 is sent infrared light; Said circuits for triggering 3 adopt the monostable flipflop IC2 that is made up of gate circuit F2, F3, and the controllable type multivibrator that resistance R 7, R8, capacitor C 3 that said oscillating circuit 4 employings are connected with its periphery by 555 time-base circuit IC3 constitutes is though the output of monostable circuit is cyclic variation with input signal; But multivibrator can starting of oscillation, does not send starting impulse.But when microprocessor IC4 quit work for some reason, monostable circuit output was high level output, makes 555 time-base circuit IC3 starting of oscillations; Make the 12nd pin of microprocessor IC4 also be high level state, after microprocessor IC4 judges, by the 13rd pin output low level of microprocessor IC4; Make triode Q1 conducting; The relay J adhesive, its contact J-1 is closed, makes load get the electrician and does.
When human body human body during not in regions, when AMNI type sensor IC did not detect the infrared signal of human body radiation, when its output Out was low level, photoelectrical coupler IC1 was output as high level; The frequency of its 12nd pin of microprocessor IC4 scanning I/O port is lower than set point, after the inner judgement of microprocessor IC4, delays time after 15 seconds, by the 13rd pin output high level of microprocessor IC4; Triode Q1 is ended, and relay J discharges, and its contact J-1 breaks off; Make load outage and quit work, reach energy-conservation, automatically control; Also can avoid various interference, start reliable, safe in utilization.
An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
