1、摘要随着汽车数量的逐年递增,汽车被盗问题也日益严重,盗窃手段的多样化和专业化严重挑战着汽车的安全防护装置。本文提出了一种多功能汽车安全监视系统,设计了基于振动检测和彩信报警的防盗功能,并且一改传统报警器被动服务的特点,能够主动记录汽车周围的异常情况,具有较高的实际应用价值。首先,本文提出了一种多功能汽车监视系统的方案。该方案能够依靠振动检测对拖车、偷盗轮胎和砸车玻璃等特殊的盗窃行为进行准确的判断,利用多个摄像头采集的图像拼接成一副大视角的现场图片,结合GPS电子地图信息,以彩信的形式向车主报警;还能够主动检测汽车周围的异常情况,记录下必要的视频信息。其次
2、,本文实现了振动检测功能、图像拼接功能以及彩信发送功能。硬件设计包括MSP430单片机、振动检测模块、彩信模块、GPS接收机模块的外围电路设计;软件设计包括单片机对振动检测信号的采集及判断,Linux系统下双摄像头图像的采集和拼接,以及彩信发送的实现。最后通过搭建实物模型,对多功能汽车监视系统进行功能和性能验证。实验结果表明系统能够完整的实现振动检测防盗报警功能。关键词:汽车防盗,振动检测,图像拼接,GPS,彩信AbstractAsthenumberofcarincreaseseveryyear,theproblemofvehiclestolenhasb
