Accompanying drawing 3 is its host circuit figure.
In conjunction with the accompanying drawings embodiment of the present utility model is described below:
Shown in accompanying drawing 1, power circuit+6V directly powers to detection circuit.Power circuit+a start delay circuit being arranged between 6V and the control circuit, the start back time-delay regular hour is again to control circuit confession+6V power supply.The output signal of infra-red detection circuit is delivered to control circuit.Controlling trigger circuit+6V on/off by control circuit.By selected doorbell of switch K or warning duty.No matter doorbell or warning duty all will drive loudspeaker Y by audio amplifier circuit and send doorbell or warning sound, and it is shinny synchronously to control illuminating lamp by control circuit simultaneously.When the high sound of needs was sought help, K closed a switch
3, from bridge rectifier come out+the 12V DC voltage is directly as the audio amplifier circuit power supply, thereby loudspeaker can send stronger sound.
Shown in accompanying drawing 2, BH is pyroelectric infrared sensor, selects P228 for use.IC
1a～dBe four high guaily unit integrated circuit LM324.IC wherein
1a, IC
1bBe the two poles of the earth linear amplifier, IC
1cFor voltage ratio than shaping circuit, IC
1dBe the time-delay amplifier.Regulator potentiometer W can change capacitor C
10Charging rate, thereby change IC
1dThe length of time-delay is provided with time of fire alarming length thus.It is many with an integrated circuit to aim at time-delay unlike above-mentioned patent, and circuit obtains simplifying.This infrared sensor and circuit thereof are contained in the housing, are installed in top outdoors.
Need do the doorbell time spent daytime, with K
2Push 2.Come man-hour in front of the door, the faint infrared signal that human body radiation goes out is received by sensor BH, and converts electric signal to.The A end transfers low level to by high level, makes the V of control circuit
2Become by conducting and to end.J
