毕业设计基于CAN总线技术胎压监测系统.doc

摘 要 伴随着工业经济的快速发展，汽车已经在社会上得到大量的使用，方便和便捷的公路交通，给人们带来了很多便利，但是伴随着汽车的大量使用，各种恶性的公路交通事故给人们的生命安全和社会经济的发展带来了严重的危害和损失。统计表明引起交通事故增长的主要原因是由于在公路行驶当中因轮胎故障所引起的轮胎爆胎，因而如何解决和防止轮胎爆胎，已成为全球的首要问题。为了防止和解决轮胎爆胎，轮胎压力监测系统（TPMS）作为汽车三大安全系统之一，与汽车安全气囊、防抱死制动系统（ABS）一起被大众认可并受到应有的重视。在当前的汽车产业中，出于对安全性、舒适性、方便性、低公害、低成本的要求，各种各样的电子控制系统被开发了出来CAN总线协议所具有的高可靠性和良好的错误检测能力受到重视，被广泛应用于汽车计算机控制系统和环境温度恶劣、电磁辐射强和振动大的工业环境Along with the rapid development of industrial economy, the car has been in the community with a lot of use, convenience and ease road traffic, a lot of convenience to the people, but along with the extensive use of motor vehicles, a variety of malignant road traffic accidents to people safety of life and socio-economic development has brought serious damage and loss. Statistics show that the main cause accidents growth is a tire puncture caused by tire failure in which the highway, and thus how to solve and prevent the tire puncture has become the worlds most important issue. In order to prevent and solve tire puncture, the tire pressure monitoring system (TPMS) thus came into being, and as one of the car the three safety systems, and automotive airbags, anti-lock braking system (ABS) with public recognition and due attention. Meanwhile, in the current automotive industry, for safety, comfort, convenience, low pollution, low-cost requirements of a variety of electronic control system is developed, the CAN bus protocol has a high reliability and error detection capabilities attention, is widely used in harsh automotive computer control systems and the ambient temperature, the strong electromagnetic radiation and vibration of industrial environments. Run security issues for todays automotive, tire pressure monitoring system based on CAN bus technology in design, as well as how to improve vehicle safety performance for the CAN bus communication protocol technology has a very important practical significance. This paper a systematic study of the knowledge of the CAN bus technology and tire pressure moni
