Electronic anti-theft system for automotive engine

Abstract

The invention discloses an electronic anti-theft system for an automotive engine, which comprises an ECU (Electronic Control Unit), an automobile ignition lock cylinder, a movable door, an identification device, a vibration sensing module, a GPS (Global Positioning System) positioning device and a microcontroller, wherein the movable door is mounted at a key opening and is provided with a power device; the identification device is mounted at one side of the key opening; the vibration sensing module is mounted in a body; the GPS positioning device is embedded and mounted in the outer wall of the engine; the input end of the microcontroller is connected with the identification device and the vibration sensing module; the output end of the microcontroller is connected with the movable door, the ECU, the automobile ignition lock cylinder and the GPS positioning device. The electronic anti-theft system for the automotive engine, which is disclosed by the invention, integrates voice print verification with palm veins into one whole body, carries out defense by three aspects of the ECU, the automobile ignition lock cylinder and the key opening, and meanwhile, cooperates with the GPS positioning device to carry out positioning on a position of a vehicle; the GPS positioning device is embedded and mounted in the outer wall of the engine and is inconvenient to disassemble, so that burglar resistance of the vehicle is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile anti-theft systems, in particular to an automobile engine electronic anti-theft system. Background technique [0002] The most widely used car anti-theft is generally mechanical anti-theft and electronic anti-theft. [0003] The main principle of mechanical anti-theft is to lock a certain mechanism on the car so that it cannot play its due role, such as transmission gear locks, steering wheel locks, brake pedal locks, etc., the price ranges from tens of yuan to hundreds of yuan. wait. Mechanical anti-theft can prolong the time of theft, but it cannot send an alarm, and there are many means of cracking. [0004] Electronic anti-theft mainly uses wireless signals and chip passwords to lock the ignition or start to achieve the purpose of anti-theft, and has anti-theft and sound alarm functions. This is the most widely used anti-theft method in the market. Such as various remote controls and ch...
