Abstract
The invention provides a burglar alarm device for a balcony. The burglar alarm device comprises a human body inducing module circuit, a voltage comparator circuit and a sound-light alarm circuit, wherein the human body inducing module circuit adopts a human body infrared induction module HC-SR501; the voltage comparator circuit adopts an LM358 chip; the sound-light alarm circuit comprises an alarm, a light emitting diode and controllable silicon; the human body inducing module circuit is used for detecting infrared heat release of a human body, and can control the voltage comparator circuit to output an up level when the detection result shows that a person intends to enter a room from the balcony, then the controllable silicon is triggered to be conducted, and the sound-light alarm circuit sends out sound and light continuously to warn and awe a thief and remind the owner of the room that the person intends to enter the room from the balcony. Therefore, the balcony mounted with the burglar alarm device has a burglar alarm function even when no metal anti-theft mesh is mounted.
Description
Technical field
The present invention relates to the burglar alarm that a kind of thief of preventing registers one's residence from balcony, belong to application electric technology field.
Background technology
Nowadays the balcony of most residents house and window have all installed various types of anti-theft net, fundamental purpose is committed theft to prevent thief from entering indoor from window and balcony, although anti-theft net can effectively play antitheft effect, living balcony can affect the comfort level of resident family and the overall appearance degree of external wall of house after installing anti-theft net to a great extent.Therefore be necessary that the warning device designing a kind of automatic induction is to replace anti-theft net, when thief is near window balcony, warning device can automatically be responded to and constantly send acousto-optic warning, plays the effect of fright thief.And balcony is without the existence of anti-theft net, people can obtain the better visual field and the more comfortable life sensation loosened.
Summary of the invention
The object of this invention is to provide the burglar alarm that a kind of thief of preventing registers one's residence from balcony, also can play theft-proof alarm function to realize balcony when there is no metal anti-theft net.
The concrete technical scheme that the present invention takes is as follows:
A kind of theft-proof alarm for balcony, it is characterized in that: this device comprises human body induction module circuit, voltage comparator circuit and sound light alarming circuit, wherein human body induction module circuit adopts human body infrared induction module HC-SR501, voltage comparator circuit adopts LM358 chip to build, and sound light alarming circuit adopts alarm, light emitting diode and controllable silicon to build.
1 pin of human body infrared induction module HC-SR501 connects+5V power supply through switch S 1, and 2 pin connect the 3 pin positive input terminals of LM358 chip U1,3 pin ground connection; The 2 pin negative input ends of the adjustment termination LM358 chip U1 of adjustable resistance RV1, two stiff end one end of adjustable resistance RV1 connect+5V power supply through switch S 1, other end ground connection; 8 pin of LM358 chip U1 connect+5V power supply through switch S 1,4 pin ground connection, access the control end of the controllable silicon U2 of warning circuit after 1 pin output terminal series resistor R2; The plus earth of controllable silicon U2, the negative pole of anode sending and receiving optical diode D1 and one end of alarm LS1, one end of the positive pole connecting resistance R1 of light emitting diode D1, the other end of resistance R1 and the other end of alarm LS1 connect+5V power supply through switch S 1 jointly.
Beneficial effect of the present invention is: this theft-proof alarm for balcony is detected infrared human body heat releasing by human body induction module circuit, when having detected that human desires enters from balcony, human body induction module circuit can export high level by control voltage comparator circuit, and then triggering controlled silicon conducting, make warning circuit continue to send acousto-optic warning fright thief, also notify that owner has human desires to enter from balcony.Therefore, having installed the balcony of this device, even if when not installing metal anti-theft net, also can play the effect of burglar alarm, balcony is without the existence of anti-theft net, and people can also obtain the better visual field and the more comfortable life sensation loosened.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of this theft-proof alarm for balcony.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, this theft-proof alarm for balcony comprises human body induction module circuit, voltage comparator circuit and sound light alarming circuit, wherein human body induction module circuit adopts human body infrared induction module HC-SR501, voltage comparator circuit adopts LM358 chip to build, and sound light alarming circuit adopts alarm, light emitting diode and controllable silicon to build.
1 pin of human body infrared induction module HC-SR501 connects+5V power supply through switch S 1, and 2 pin connect the 3 pin positive input terminals of LM358 chip U1,3 pin ground connection; The 2 pin negative input ends of the adjustment termination LM358 chip U1 of adjustable resistance RV1, two stiff end one end of adjustable resistance RV1 connect+5V power supply through switch S 1, other end ground connection; 8 pin of LM358 chip U1 connect+5V power supply through switch S 1,4 pin ground connection, access the control end of the controllable silicon U2 of warning circuit after 1 pin output terminal series resistor R2; The plus earth of controllable silicon U2, the negative pole of anode sending and receiving optical diode D1 and one end of alarm LS1, one end of the positive pole connecting resistance R1 of light emitting diode D1, the other end of resistance R1 and the other end of alarm LS1 connect+5V power supply through switch S 1 jointly.
After on balcony installing this warning device, close a switch during unlatching S1, when thief not detected, the 2 pin output low levels of human body infrared induction module HC-SR501, the 1 pin output low level of voltage comparator LM358 chip U1, controllable silicon U2 not conducting, sound light alarming circuit does not work.When human body infrared induction module HC-SR501 detect have thief for entering outside balcony time, its 2 pin exports high level, the 1 pin upset of voltage comparator LM358 chip U1 is high level, trigger controllable silicon U2 conducting, the light emitting diode D1 of sound light alarming circuit lights, alarm LS1 sounds the alarm, and prompting homeowners has people to enter from balcony, thus plays the effect of fright thief.
