A Car Theft Deterrent System Research Based On Multi-sensor Fusion Technology

We developed a car theft deterrent system based on multi-sensor fusion technology by utilizing the superiority of the theory in order to enhance the reliability and reduce the false alarms for the system.First, some investigations in the car theft deterrent domain had been finished both here and abroad and many car lost modes had been analyzed too. Then the anti-theft structure model was constructed.The selections of the system's sensors, microprocessors, actuators, and the accessories were introduced, the hardware and software had been designed and the system prototype had been manufactured by using PCB technology and "Embedded workbench" integrated development environment, the applications and debugging methods had been summarized. Also, we used the "K-S nonparametric test" and the statistical software SPSS to design the monitoring module, thus we could control the system's reliability in some degree.The developing process of the car theft deterrent system used modularizing method. The power block, sense block, alarm block and CPU block had been designed in detail after the system overall design. Some special applications had been found especially for anti-theft use in the system character test, which had been carried out for the part and the whole product inspection.The test results show that the car theft deterrent system based on multi-sensor fusion can provide more precise alarms, and also possesses some environmental protection performance. The prototype achieved the design objective, and established a new design direction for the development of the car anti-theft system.
