With the continuous development of scientific technology, scientific researchers need to develop anti-theft devices with different structures in order to deal with the continuously upgraded car stealing mode. Currently, burglar alarms can be classified into three categories, mechanical burglary prevention, electronic burglary prevention and cyber burglary prevention, according to their structures and functions. The mechanical anti-theft is mainly achieved by locking, clutching, braking, an accelerator or a gear, but only the anti-theft is achieved without alarming, so that at present, the market is rare, and the mechanical anti-theft belongs to a product. Electronic anti-theft is a common anti-theft product in the current market, and the aim of anti-theft is achieved mainly by locking ignition or starting.
