Abstract
The utility model provides an anti-theft alarm device which comprises a power supply, an alarm circuit, a conducting wire mesh, an anti-alarm device and a high loudness loudspeaker. When someone invades illegally, the alarm circuit is triggered to send an alarm signal, the 120-dB high loudness loudspeaker outputs an alarm sound to cause the attention of people, and at the same time an illegal invader is threatened. The anti-theft alarm device has a low cost and can be self-made and self-installed.
Description
Technical field
The utility model relates to a kind of burglar alarm, and particularly the illegal invasion autoalarm belongs to the electron controls technology field.
Background technology
At present, various burglar alarms are arranged, as intelligent wireless burglar alarm, the infrared invisible antitheft correlation of wireless electron, interconnection type burglar alarm central control system etc., being extensive use of of burglar alarm is to the antitheft positive role that played of public security.
Because burglar alarm has been to a certain extent for the household property safety provides favourable guarantee, thereby obtained using more widely.However, also often have some resident families at night stolen molecule climb window theft, wherein one of reason is that existing alarm has blemish in an otherwise perfect thing: cost is higher, perhaps needs the professional to install.
Summary of the invention
The purpose of this utility model is to propose a kind of burglar alarm, as a kind of of existing burglar alarm replenished.
The utility model is achieved in that a kind of burglar alarm, it is characterized in that, comprising: power supply, warning circuit, traverse net, anti-alarm element, high loudness loudspeaker.
Power supply is the warning circuit power supply, and warning circuit produces alerting signal, and traverse net provides trigger pip to warning circuit, the trigger pip that anti-alarm element shielded conductor net provides to warning circuit, and high loudness loudspeaker provide alarm sound output.
Described traverse net is made of enameled wire and the anti-warning wire element of a diameter less than 0.2 millimeter.
Described anti-alarm element is a lead, and is in parallel with traverse net.
The utility model uses above-mentioned critical piece to constitute according to above-mentioned design.Its principle of work is: power supply is the warning circuit power supply, and warning circuit produces alerting signal, and traverse net provides trigger pip to warning circuit, the trigger pip that anti-alarm element shielded conductor net provides to warning circuit, and high loudness loudspeaker provide alarm sound output.Traverse net is installed in the place that door and window etc. might be broken in, and when the people breaks in, causes fine enamelled wire to disconnect, trigger warning circuit and send alerting signal, and by 120 decibels high loudness loudspeaker output alarm sound, come into the picture, also deter illegal invasion person simultaneously.As the people is legal when entering, artificially connect anti-alarm element, avoid triggering warning circuit and send alerting signal.
Advantage of the present utility model and effect:
(1) user can utilize existing material self-control, and traverse net can arbitrarily be set at any time.
(2) cost is lower, does not need the professional to install.
Description of drawings
Fig. 1 is circuit block diagram of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Please referring to Fig. 1, a kind of burglar alarm comprises: power supply 1, warning circuit 2, traverse net 3, anti-alarm element 4, high loudness loudspeaker 5.
Power supply 1 is warning circuit 2 power supplies, warning circuit 2 produces alerting signal, and traverse net 3 provides trigger pip for warning circuit 2, and anti-alarm element 4 is in parallel with traverse net 3, be used for the trigger pip that shielded conductor net 3 provides for warning circuit 2, high loudness loudspeaker 5 provide alarm sound output.
Traverse net is installed in the place that door and window etc. might be broken in, and when the people breaks in, causes fine enamelled wire to disconnect, trigger warning circuit and send alerting signal, and by 120 decibels high loudness loudspeaker output alarm sound, come into the picture, also deter illegal invasion person simultaneously.As the people is legal when entering, artificially connect anti-alarm element, avoid triggering warning circuit and send alerting signal.
