Pedestal includes the first cavity, and hall sensor, buzzer siren and single-chip microcomputer are provided with the first cavity, is set on antitheft pedestal
Have switching device, single-chip microcomputer is connected with hall sensor, buzzer siren and supply unit respectively, switching device respectively with power supply
Device is connected with buzzer siren, and the chain stretching device includes slider of zipper fastener, and magnetic magnet is provided with slider of zipper fastener.
Switching device is opened, after user draws chain stretching device, slider of zipper fastener is put into the first cavity, because drawing
Chain head is provided with magnetic magnet, and the hall sensor in the first cavity detects that magnetic field becomes strong and sends a signal to single-chip microcomputer,
Single-chip microcomputer control buzzer siren makes buzzer siren be in the state being stopped, when slider of zipper fastener takes out out of first cavity
When, hall sensor detects that magnetic field dies down and sends a signal to single-chip microcomputer, and single-chip microcomputer control buzzer siren makes buzzing report
Alert device is in the state of work, and now buzzer siren sends warning reminding, can be effective so when chain stretching device is opened
The user of knapsack is reminded, plays antitheft effect.
As further improvement of the utility model, the metal that can be inhaled with magnetic iron phase is additionally provided with the first cavity
Block.
As further improvement of the utility model, USB interface device is provided with antitheft pedestal.
