Abstract
The utility model provides an area initiative alarm function's burglar alarm, its circuit comprises initiative light alert circuit and voice alarm circuit, initiative light alert circuit includes 555 integrated circuit U1, resistance R1, R2, electric capacity C1 and LED lamp D1, voice alarm circuit includes that the human response module U2 of HC -SR501, LM358 transport and put U3, resistance R3, R4, R5, NPN triode Q1 and buzzer BUZ. This burglar alarm installs on the balcony, and when the balcony did not have the robber and invades, this burglar alarm passed through the LED lamp and constantly glimmers, plays the effect of initiatively warning other people, if when balcony emergence robber invaded, this burglar alarm can also send the alarm tone through the buzzer, plays the dual function of fright robber and warning. Owing to having initiative alarm function, can carry out the light warning to the robber in advance, form the fright to it, make it take the initiative and give up committing theft the idea.
Description
Technical field
The utility model relates to a kind of burglar alarm, and specifically a kind of burglar alarm with active alarm function, belongs to application electric technology field.
Background technology
In city, the work place of many people is left home comparatively far away, and coming out early and return late is a kind of normality, and therefore, in order to protect family's property, prevent robber from balcony burglary, burglar alarm has on balcony been installed by many families.The burglar alarm in market, requires to be arranged on shelter, in case robber finds usually.This concealed burglar alarm; can only play and find robber's invasion and then alarm function; can not produce the effect of initiatively warning, when this type of burglar alarm is reported to the police, robber often enters; at this moment robber can select to risk everything on one attempt on the contrary; continuation is left after committing theft rapidly, and therefore we wish that this type of alarm can have a function initiatively warned, and namely clearly warns robber and is provided with burglar alarm herein; make it dare not make decision of committing theft easily, thus protect the safety of family's property further.
Utility model content
The purpose of this utility model is to provide a kind of burglar alarm with active alarm function, to solve the problem that traditional anti-theft alarm does not possess initiatively alarm function.
The concrete technical scheme that the utility model is taked is as follows:
With a burglar alarm for active alarm function, it is characterized in that: the circuit of described burglar alarm is made up of active light warning circuit and sound warning circuit;
Described active light warning circuit comprises 555 integrated circuit U1, resistance R1, R2, electric capacity C1 and LED D1, wherein 4 pin of 555 integrated circuit U1 and 8 pin connect+5V power supply, contact resistance R1 between 2 pin and 3 pin, 2 pin are connected with 6 pin, 1 pin ground connection, 2 pin also connect one end of electric capacity C1, the other end ground connection of electric capacity C1,3 pin of 555 integrated circuit U1 also access the positive pole of LED D1 after series resistor R2, the minus earth of LED D1;
Described audible alarm circuit comprises HC-SR501 human body induction module U2, LM358 amplifier U3, resistance R3, R4, R5, NPN triode Q1 and hummer BUZ, wherein 1 pin of human body induction module U2 connects+5V power supply, 3 pin ground connection, 2 pin connect 3 pin of amplifier U3, one end of resistance R3 and R4 connects 2 pin of amplifier U3 jointly, the other end of resistance R4 and 8 pin of amplifier U3 connect+5V power supply, the other end of resistance R3 and the 4 pin ground connection of amplifier U3, the base stage of triode Q1 is accessed after the 1 pin series resistor R5 of amplifier U3, the grounded emitter of triode Q1, collector connects one end of hummer BUZ, 3 pin of 555 integrated circuit U1 of another termination active light warning circuit of hummer BUZ.
The beneficial effects of the utility model are: the burglar alarm of this band active alarm function is installed on balcony, and when balcony is invaded without robber, this burglar alarm is constantly glimmered by LED, plays the effect initiatively warning other people; If when balcony generation robber invades, this burglar alarm also sounds the alarm by hummer, plays the double action of fright robber and warning.Due to active alarm function, its effect is better than the effect of common burglar alarm, when robber not yet enters balcony, can carry out light warning in advance to robber, forms fright to it, makes it initiatively abandon idea of committing theft.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the circuit of the burglar alarm of this band active alarm function is made up of active light warning circuit and sound warning circuit.Described active light warning circuit comprises 555 integrated circuit U1, resistance R1, R2, electric capacity C1 and LED D1, wherein 4 pin of 555 integrated circuit U1 and 8 pin connect+5V power supply, contact resistance R1 between 2 pin and 3 pin, 2 pin are connected with 6 pin, 1 pin ground connection, 2 pin also connect one end of electric capacity C1, the other end ground connection of electric capacity C1,3 pin of 555 integrated circuit U1 also access the positive pole of LED D1 after series resistor R2, the minus earth of LED D1.Described audible alarm circuit comprises HC-SR501 human body induction module U2, LM358 amplifier U3, resistance R3, R4, R5, NPN triode Q1 and hummer BUZ, wherein 1 pin of human body induction module U2 connects+5V power supply, 3 pin ground connection, 2 pin connect 3 pin of amplifier U3, one end of resistance R3 and R4 connects 2 pin of amplifier U3 jointly, the other end of resistance R4 and 8 pin of amplifier U3 connect+5V power supply, the other end of resistance R3 and the 4 pin ground connection of amplifier U3, the base stage of triode Q1 is accessed after the 1 pin series resistor R5 of amplifier U3, the grounded emitter of triode Q1, collector connects one end of hummer BUZ, 3 pin of 555 integrated circuit U1 of another termination active light warning circuit of hummer BUZ.
The principle of work of this circuit is as follows:
In active light warning circuit, 555 integrated circuit U1 and resistance R1, electric capacity C1 form a square-wave oscillator, its vibration square wave exported is loaded on LED D1 through resistance R2, and LED D1 is constantly glimmered and forms initiatively warning light, LED D1 is arranged on balcony and obviously locates.
In audible alarm circuit, whether HC-SR501 human body induction module U2 is responsible for detecting has people to invade from balcony, during unmanned invasion, and its output low level, when someone invades, it exports high level; And the output terminal of LM358 amplifier U3, resistance R4, R3 and human body induction module U2 forms a voltage comparator, during unmanned invasion, amplifier U3 output low level, triode Q1 not conducting, hummer BUZ does not work; When someone invades, amplifier U3 exports high level, triode Q1 conducting, and hummer BUZ works, and has sent rhythm alarm song.
