汽车CAN总线防盗系统毕业设计.doc

摘 要 目前我国汽车工业的飞速发展，汽车防盗的产品越来越多，于此原因设计一种基于S3C2410汽车防盗系统。 本课题选用S3C2410为核心控制器，利用多普勒微波传感器对汽车的震荡进行检测，用USB摄像头发送图像信息给汽车用户，利用S3C2410的USB接口连接个摄像头，将摄像头拍摄的图像发送给汽车用便于一旦汽车被盗时提供图像资料，有利于案件的破获。本设计总体分为五大模块，主控制器模块、信息采集模块(传感器)、USB、摄像头模块、无线通信模块(GPRS MODEM )和图像压缩模块。主控制模块包括S3C2410、触摸屏等；信息采集模块包括传感器、霍尔传感器等；USB、摄像头模块是收集图像资料；无线通信和图像压缩模块是将收集的图像发送给用户。 汽车CAN总线防盗技术是将防盗和网络有效的联系起来，将防盗智能化，突破传统的机械式防盗的弊端，但是，CAN总线防盗价格昂贵，暂时还不能在汽车领域广泛运用，只能在高档汽车上使用，将来运用更新的技术将CAN总线防盗广泛运用于汽车上是总线防盗的发展方向。 CAN总线；自动控制；局域网络 Abstract With the fast development of the auto industry of our country at present, there are more and more theft-proof products of automobile and we design one kind automobile burglary-resisting system in this reason based on the S3C2410. This subject selects S3C2410 for use as the key controller. It makes use of Utilize Dopplers microwave sensor to gauge shock of the automobile. It makes a video recording with USB camera to give image information to automobile users. It uses USB interface of S3C2410 to join a lens, sending automobile users the images taken by the camera, which offers image data in case of being stolen, thus helping the cracking of the case. Overall, it is divided into five major modules: the master controller module, the information-collecting module (the sensor) , USB, the lens module, the wireless communication module (GPRS MODEM ) and the image-compressing module, with the main controlling module including S3C2410, touch-sensitive screen, etc., the information-collecting module including the sensor, Halls sensor, etc., USB and lens module to collect the picture materials, and the wireless communication module and the picture- compressing module to send the collected picture to users. The theft-proof technology of CAN bus for the automobile is to link up guarding against theft with the network effectively, making It intelligent to guard against theft, so this breaks through the drawback from the theft-proof of traditional machinery type. However, CAN bus guarding against theft costs
