Embodiment Construction
[0040] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0041] An anti-theft method and system of the present invention is based on a security system composed of an infrared sensor 2, an ultrasonic sensor 3, an electromagnetic lock 4, and a mechanical lock. The "power-on lock" in the text refers to energizing the electromagnetic lock 4 so that the electromagnetic lock 4 starts. Locking, the "keyhole" in the text refers to the keyhole of the mechanical lock. Through the technical solution disclosed in the present invention, when the system is activated when the user leaves, the electromagnetic lock 4 can be energized and locked to provide corresponding protection when an intruder attempts to invade by breaking the mechanical lock.
[0042] Such as figure 1 as shown, fig...

The invention relates to an antitheft method and system. The method comprises that a confidence distance, first determination time and second determination time are set in advance; time T1 when an intruder stays in the outdoor is obtained; a distance H between an object outside a lockhole and the lockhole is obtained, and time T2 when the H is lower than the confidence distance is recorded; and whether locking conditions are met is determined, and a lock is electrified and locked when one or multiple locking conditions(s) is / are met. The system comprises a processing device, an infrared sensor, a supersonic sensor, an electromagnetic lock and a mechanical lock, and the processing device comprises a presetting device, a signal collector and a determining device. The user sets the confidence distance, first determination time and second determination time in advance, the time T1 when the intruder stays in the outdoor and the distance H between the object outside a lockhole and the lockhole are obtained, the time T2 when the H is lower than the confidence distance is recorded, the electromagnetic lock is electrified and locked when signal collection is interrupted or housebreaking by picking the lock occurs or the intruder stays for a long time, and the system safety is improved.
Description
technical field [0001] The invention relates to the field of the Internet of Things, in particular to an anti-theft method and system. Background technique [0002] Anti-theft devices are widely used in the security field, and existing anti-theft devices are usually applied to technologies such as fingerprint identification, password identification, remote control and IC card. In areas such as homes and offices, anti-theft devices usually include a mechanical lock installed on the door and an electromagnetic lock installed between the door and the door frame to provide protection for the protected area through the mechanical lock and the electromagnetic lock. The safety of the above-mentioned anti-theft device is not high enough. When an intruder tries to invade by breaking the mechanical lock, the electromagnetic lock cannot provide corresponding protection. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the pre...
