Description
Technical field
The present invention relates to warning device field, more particularly to a kind of article anti-theft alarm.
Background technology
As the improvement of people's living standards, the economic situation of people is generally preferable.But the phenomenon of theft still has
Occur.Therefore, it is just very necessary that burglar alarm is installed in the family.
The complicated of burglar alarm, response speed are slow at present, reliability is poor.
The content of the invention
Present invention mainly solves above-mentioned technical problem, proposes a kind of article anti-theft alarm, and the present invention can carry out article
Burglar alarm, improve the stability and security of alarm.
The invention provides a kind of article anti-theft alarm, the article anti-theft alarm includes：Sensor S1, it is single-phase can
Control silicon VS, IC, audio power amplifying circuit and loudspeaker B；
The article anti-theft alarm also includes：Multiple resistance and electric capacity；
The IC uses the simulated sound application specific integrated circuit of CW9561 types four.
Further, the anti-theft warning circuit also includes power supply, and the power supply is 9V.
Further, the anti-theft warning circuit also includes fin.
Further, the sensor S1 is mercoid switch.
Further, the audio power amplifying circuit is triode V1.
Further, the single-phase silicon-controlled VS is one-way SCR model MCR100-6.
A kind of article anti-theft alarm provided by the invention, the alarm using when be placed in antitheft, anti-animal part, such as family
On electrical appliance, door, window, motorcycle or bicycle and other items.Object one is moved, and alarm is issued by sound.When someone is in
When being not required to alarm, turn off the switch of alarm.This alarm arrangement is simple, cost is low, the response time is fast, security
Good, good reliability, it is very convenient to be arranged on antitheft, anti-animal product, 24 hours prisons in real time can be carried out to family's visual plant
Control, will not report by mistake and fail to report.
Brief description of the drawings
Fig. 1 is the structural representation of article anti-theft alarm provided by the invention.
Embodiment
For make present invention solves the technical problem that, the technical scheme that uses and the technique effect that reaches it is clearer, below
The present invention is described in further detail in conjunction with the accompanying drawings and embodiments.It is understood that specific implementation described herein
Example is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that for the ease of description, accompanying drawing
In illustrate only part related to the present invention rather than full content.
Fig. 1 is the structural representation of article anti-theft alarm provided by the invention.As shown in figure 1, the embodiment of the present invention carries
The article anti-theft alarm of confession includes：Sensor S1, single-phase silicon-controlled VS, IC, audio power amplifying circuit and raise
Sound device B；
The article anti-theft alarm also includes：Multiple resistance and electric capacity；
The IC uses the simulated sound application specific integrated circuit of CW9561 types four.
Wherein, the anti-theft warning circuit also includes power supply, and the power supply is 9V.
Wherein, the anti-theft warning circuit also includes fin.
Wherein, the sensor S1 is mercoid switch.
Wherein, the audio power amplifying circuit is triode V1.
Wherein, the single-phase silicon-controlled VS is one-way SCR model MCR100-6.
Article anti-theft alarm work principle provided in an embodiment of the present invention：After battery main switch K closures, s1 mercoid switches
(its relative tilt line 30.Established angle) contact is off-state in the case of without sound, one-way SCR VS trigger current
It is that zero, VS is in blocking state, at this moment main power circuit does not work equivalent to open circuit, simulated sound integrated circuit, and loudspeaker B is noiseless
Sound, complete machine power consumption are zero.Once alarm is moved, or is moved article and caused mercury tilt switch angle to change, it is caused to touch
Point is connected, then controllable silicon VS trigger electrode G will obtain trigger current to turn on by resistance R1 (10kD), integrated circuit Ic works
Make, the electric signal of simulation police car sound is exported from OUT terminal, alarm is continuously sent through triode V1 amplifications and drive the speaker B.Electricity
It is in order to reduce power supply E and one-way SCR VS alternating current internal resistance, especially when battery electric quantity deficiency, if not having to hold C1
C1, it will make alarm decrease or distortion.SB is to release alarm.
The alarm using when be placed in antitheft, anti-animal part, such as household electrical appliance, door, window, motorcycle or bicycle thing
On product.Object one is moved, and alarm is issued by sound.When someone, which is in, is not required to alarm, turn off the switch of alarm.
This alarm arrangement is simple, cost is low, the response time is fast, security is good, good reliability, very convenient installed in antitheft, anti-
On animal product, monitoring in real time in 24 hours can be carried out to family's visual plant, will not report by mistake and fail to report.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its is right
Technical scheme described in foregoing embodiments is modified, and either which part or all technical characteristic are equally replaced
Change, the essence of appropriate technical solution is departed from the scope of various embodiments of the present invention technical scheme.
