Practical household anti-theft alarm

Abstract

The invention relates to a practical household anti-theft alarm, and belongs to the technical field of anti-theft alarming. According to the technical scheme of the invention, the practical household anti-theft alarm comprises a detection launching module for detecting illegal entering and launching an anti-theft triggering signal, wherein the detection launching module is wirelessly connected with a receiving and alarming module; and when the detection launching module launches the anti-theft triggering signal to the receiving and alarming module, the receiving and alarming module carries out oscillation alarm and audible alarm after decoding and judging the anti-theft triggering signal. According to the practical household anti-theft alarm disclosed by the invention, the passive sensing detection is adopted, thus improving the accuracy and prolonging the service life; a chip with address coding and decoding functions is also adopted, thus solving the problem of false alarm of multiple houses; a lithium battery charging and discharging protective circuit is designed, so that the service life of a lithium battery is prolonged, and the use safety is improved; and stable working voltage is supplied for a portable anti-theft receiving circuit by a boost circuit, so that the anti-theft receiving circuit is simple in design, low in cost, timely in alarm and suitable for being used by most houses.

Description

technical field [0001] The invention relates to an anti-theft alarm device, in particular to a practical family anti-theft alarm, which belongs to the technical field of anti-theft alarms.
