Motor vehicle antitheft system based on information fusion

Abstract

The invention discloses a motor vehicle antitheft system based on information fusion. The motor vehicle antitheft system comprises a data detection and control terminal and a mobile terminal connectedwith the data detection and control terminal; the data detection and control terminal comprises a processor module, a monitoring module, a signal processing module, an alarming module, a communication module, an executing module and a power supply module; the monitoring module comprises a microwave Doppler sensor array, a vibration sensor array, an inclined angle sensor array, a pyroelectric infrared sensor array and a Hall switch device array, and optocoupling isolating modules which are connected with the microwave Doppler sensor array, the vibration sensor array, the inclined angle sensorarray, the pyroelectric infrared sensor array and the Hall switch device array in a one-to-one corresponding mode. An amplifier circuit of a three-level amplifying structure is provided, a tri-amplification structure is designed, the converting speed of the amplifier is obviously increased, and the motor vehicle antitheft system is ingenious in design and worthy of popularization.

Description

technical field [0001] The invention belongs to the field of intelligent vehicle monitoring, in particular to a motor vehicle anti-theft system based on information fusion. Background technique [0002] With the improvement of living standards, owning a private car has become one of the signs that a family enters a fashionable and modern life. But along with the increase in the number of motor vehicles, thieves have also begun to set their sights on motor vehicles as high-end consumer goods. Although most of the current motor vehicles are equipped with original anti-theft devices, there are also various brands of motor vehicle additional anti-theft devices on the market, but these anti-theft devices are not only focused on passively handling the situation when encountering an alarm, but also for the judgment of the alarm. The reliability of the theft process has not been paid enough attention, resulting in misreporting and omissions from time to time, which has caused a lot...
