Embodiment Construction

[0022] According to attached figure 1 As shown in the schematic diagram of the use of this anti-theft alarm, fix the main part of the anti-theft device on the zipper of the luggage, and then fix the magnetic buckle accessories on the zipper head, turn on the working switch of the alarm through the mobile phone or remote control, and then enter the alarm detection At this time, the Hall device on the alarm can detect the magnetic field of the magnetic buckle and is always in the closed state, and the alarm will always be in a silent state.

[0023] When the valuables in the bag are stolen, that is, when the Hall device and the magnetic buckle are separated to a certain distance, the Hall device in the alarm cannot detect the magnetic field of the magnetic buckle, and the alarm can detect whether the bag is locked or not through the Hall device. is opened.

[0024] At this time, the base of the triode changes from the ground level to the pull-up level, and the triode changes fr...

Abstract

The invention relates to brand-new electronic equipment capable of providing an anti-theft alarm function, in particular to an anti-theft alarm device capable of being used on any bag or article provided with a zipper. The anti-theft alarm comprises a direct-current power supply, a magnetic field detection circuit, an optional wireless module, a sound amplification circuit and a buzzer. The alarm is connected onto a bag zipper, an operating switch of the alarm is switched on through remote control, when the bag zipper is pulled open and things are stolen, a Hall device can detect the change of the magnetic field of a magnetic button and judge that the alarm is separated from the magnetic button, and then the alarm sends out an audio signal, the signal is amplified by the backward stage amplification circuit and drives the buzzer to send out an alarm sound. By means of the miniaturized size, the alarm can be used in any bag conveniently, the alarm sound exceeding 100 db is sent out from the stolen article when a theft action happens, so that an owner is well alarmed about the theft, and a thief is threatened.

Description

technical field [0001] The invention belongs to the field of electronic control, and relates to a novel alarm device which can be used for anti-theft of articles in zipper bags.
