Description

Theft-proof intelligent alarm mounted to the door or the window

The utility model relates to a kind of alarm, and it is particularly related to a kind of door window antitheft alarm that intelligent memory functional is arranged.

Existing indoor burglar alarm has miscellaneous.As human body induction type, the infrared alarm formula, the employing Doppler's principle or the like.It is simple that these alarms have, and the complexity that has cuts both ways.Baroque highly sensitive, cost is also high, and average family is difficult to accept.Sensitivity simple in structure is low, and cost is also low.These known technologies have a common fault, easily by artificial destruction, influence the warning effect, and do not have intelligent memory functional.

It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, and has intelligent memory functional, and can increase the intelligent anti-theft alarm that is applicable to indoor door and window of theft-proof sensor point simultaneously arbitrarily.

The purpose of this utility model can realize by following technical measures.

This door and window intelligent anti-theft alarm, it includes door lock and compositions such as permanent magnet, sensor and alarm, circuit, on interior door, window, permanent magnet and sensor are installed separately, the cancel switch that one of series connection is installed on the door after these sensor parallel connections is continuous with the trigger circuit of alarm, and sleep switch links to each other with the power circuit of alarm.The circuit of alarm inside is, the silicon controlled anode links to each other with the positive pole of power supply, the silicon controlled negative electrode links to each other with the feeder ear of warning, phonation circuit, and link to each other with the negative pole of sleep switch circuit with power supply by the warning phonation circuit, on silicon controlled anode and trigger electrode, be parallel with electric capacity, on silicon controlled anode and trigger electrode, also be parallel with by the cancel switch circuit sensing switch circuit in parallel more than of connecting, as triggering warning circuit.

Above-mentioned sensing switch circuit is the normally closed dry reed pipe switch.The warning phonation circuit is on the silicon controlled negative electrode, be connected with the feeder ear of sound-producing integrated circuit and an end of loudspeaker, the grounding leg of sound-producing integrated circuit links to each other by switch with the negative pole of power supply, the base stage of same triode links to each other after the sound electrical signal resistance in series of sound-producing integrated circuit, the emitter of triode links to each other with the base stage of another triode, the collector of two triodes links to each other with the other end of loudspeaker, the emitter of another triode links to each other parallel resistance on the other pin of integrated circuit with the grounding leg of integrated circuit.Electric capacity is anti-false triggering electric capacity.

Above-mentioned sensing switch circuit is because of being to select the normally closed dry reed pipe switch for use, so the warning sensing point of this alarm can be any a plurality of being formed in parallel, and is not subjected to numerical limitations.

When taking place to steal, door or window are opened, and the permanent magnet and the dry-reed tube switch that are on door or the window produce relative displacement, because dry-reed tube switch is a closed type, causes the dry-reed tube switch closure, trigger controllable silicon, controllable silicon is in conducting state, and warning circuit work is reported to the police.

The utility model has following advantage compared with the prior art:

1. all circuit is simple and reliable, has only used a spot of electronic component just to realize warning function, thereby with low cost.

2. this machine has adopted silicon-controlled device, in case trigger, still reports to the police even external circuit destroys also, has intelligent memory functional.

3. owing to adopted normally closed dry reed pipe, cost is low, and it is reliable to report to the police, and can increase the theft-proof sensor point arbitrarily.
