摘要 随着汽车制造业高速发展的步伐, 汽车事故也成为人们生活中日益严重的问题,人们对汽车安全的需求性也随之提高。而汽车事故大部分又是因为轮胎气压出现问题引起的,汽车轮胎安全问题也成为人们关注的热门话题。因此,利用汽车轮胎压力监测系统对汽车轮胎进行实时监测, 能够有效减少因轮胎安全问题引起的事故并提高燃油经济性。 本文对汽车轮胎压力监测的背景进行了阐述, 并介绍了目前国内外汽车胎压监测系统的发展情况。然后,设计了汽车轮胎压力监测系统的整体方案,确定了系统总体框架结构,并完成了主要元器件选择。根据总体设计方案,设计了以单片机STC80C51 为核心,通过 CC1100 无线芯片进行信号传输的汽车胎压监测系统。对轮胎压力监测系统各硬件模块进行了详细设计,并完成了轮胎压力监测系统采样端和接收端的软件设计。 该系统设计实现了汽车轮胎压力监测所需的基本功能,并且具有成本低、可靠性高等特点。  39654
毕业论文关键字:STC80C51;汽车;轮胎压力监测;无线传输 Abstract As the auto industry is blooming at an unprecedented speed, auto accident in People's daily life has become increasingly serious problem.In that case, people's demand for automotive safety is becoming increasingly urgent.According to some statistics most of the car accidents are caused by tire pressure problems. Obviously,car tire safety problem has raised a growing concern among the public. However, the automobile tire pressure monitoring technology can effective ly reduce accidents caused by tire safety problems, and improve fuel utilization efficiency。 My article specificly explains the background of automobile tire pressure monitoring system, and explains the development of the automobile tire pressure monitoring system home and abroad.Moreover, this paper analyzes the overall requirements of automobile tire pressure monitoring system,and designs a  TPMS system which is established on STC80C51-a single chip microcomputer whose signal was transmitted by CC1100 wireless chip. Also,it describes the performance of various components and analyzed their advantages and disadvantages, and finally decide the type-selecting scheme which is mostly suited to our aquirements.Next, we introduce the components and parts of the system, as well as the hardware module design. This design realized the basic function of automobile tire pressure monitoring system and prossesses the merits that is achieving the coexistence of low cost, high reliability characteristics and also it highly meets the design requirements.
