摘 要
为了提高汽车防盗系统的可靠性,降低汽车报警的误报率,本文在利用多传感器信息融合理论在监测领域的优势基础之上,研制了基于传感器信息融合技术的汽车防盗系统。
本文首先对国内外汽车防盗领域的现状进行了调查研究,分析了现今汽车失窃的多种模式,然后利用多传感器信息融合技术构建了汽车防盗系统的结构模型。本文研究制定了应用于该防盗系统的各种传感器、微处理器、执行器件以及系统附属的多种电子元器件的选择方案;在构建的防盗模型的基础上,设计了系统的软件、硬件;利用PCB 线路板和MSP430集成开发环境“Embedded Workbench”制作了系统的原型机;总结了防盗系统的实际应用方案和调试方法。同时,本文还将“单样本K—S非参数检验法”和统计学工具软件“SPSS”应用于汽车防盗监测模块的设计过程,使汽车防盗的可靠性能够在一定程度上得以控制。
基于传感器信息融合技术的汽车防盗系统利用模块化的思想进行设计。总体设计后,对防盗系统的电源模块、监测模块、中央处理模块和报警执行模块分别进行细化设计,最后进行整个系统的联机调试试验。本文还将设计制作的系统原型机进行了模块测试和整体性能测试。通过测试分析,确定了用于汽车防盗的实车搭载方案,为该设计的产品化奠定了坚实的基础。
测试结果表明,基于信息融合技术的汽车防盗系统能够较为准确地进行汽车防盗预警,降低了误报率,并具有经济、环保的特点。该系统基本实现了既定设计目标,为汽车防盗产品的开发提供了一个崭新的设计方向。

A Car Theft Deterrent System Research based on
Multi-sensor Fusion Technology
Abstract
We developed a car theft deterrent system based on multi-sensor fusion technology by utilizing the sur】eriority 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 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 environmen.【,the applications and debuggm_g methods had been ,we used the ‘'K-S nonparametric test'’and the statistical software SPSS to design the monitoring module. thus we could conlTol the system’s reliability in some degree.
The developing process ofthe caI"theft deterrent system used modularizing power block,sense block,alarm block and CPU block had been designed in detail after the system overall special applications had been found especially for anti-theft use in the system character test,whi
