Description

An Internet of Things anti-theft system

technical field

The utility model relates to an anti-theft system, in particular to an anti-theft system of the Internet of Things.

Background technique

As automobiles enter thousands of households of common people, automobile anti-theft has become a necessary topic. How to prevent automobiles from being stolen, timely alarm and cut off the power source in time for the theft has become more and more important. There are various types of car alarm and anti-theft horns on the market, but basically they are simple single-wire drive or vehicle body anti-theft systems with LIN bus communication. The anti-theft system driven by a single line, when the sensor detects the relevant illegal intrusion information, the car body control unit directly drives the horn to give an alarm. The alarm mode is single and the control logic is simple, which cannot be changed according to the actual needs of each country. The regulatory requirements are very different. If the car is sold abroad, it will be greatly restricted. Ordinary anti-theft horns do not have self-contained power supply and automatic detection functions. When the alarm control line is encountered or the power of the horn is cut off, the anti-theft horn will lose its function.

The body anti-theft system with LIN bus communication has diversified alarm methods and complex control logic, which can be changed according to the actual needs of each country. With the application of the anti-theft system, some thieves have gradually mastered the functions of the body anti-theft system with LIN bus communication, and the body anti-theft system with LIN bus communication has gradually produced potential safety hazards.
