基于单片机的汽车轮胎防爆监测报警系统的设计

基于单片机的汽车轮胎防爆监测报警系统的设计(任务书,开题报告,外文翻译,论文12000字)
摘要
本文阐述了目前TPMS在国内国外的发展趋势和发展现状，通过描述原理和实现方法，以及分析轮胎的性能以及爆胎条件。近年来，虽然汽车行业科技一直在进步，但是交通事故的发生数量却只增不减，给人们的生命安全和财产安全都造成了极大的威胁，其中最重要的一点原因就是爆胎，尤其是在高速行驶的时候，汽车车胎的压力会慢慢的累积，达到一个极限值的时候，就容易发生爆胎。
在这样的背景之下，TPMS系统应运而生，本文将重点介绍用于汽车的汽车车胎防爆系统的设计。该系统能实时的反应当前车胎的各种有效参数，当达到报警条件时，系统将通过声光报警来提示驾驶员。同时，TPMS还有很多将要解决的问题，比如通用性，低功耗等等。本文使用一套基于单片机的TPMS方案，本方案的原型系统分为胎压检测模块和中央监视模块，然后完成硬件构型。
首先，本文提供了硬件系统组成，并据此描述了每个模块的功能以及具体的电路设计方案。简单介绍了其功能和特性。最后我将原理图所需的各个部件通过PROTEL软件进行了调试和仿真，并做出总结以及分析。

Abstract
This paper describes the current status of the development of trends and developments in domestic and foreign TPMS, by describing the principles and implementation, and performance analysis of the tire and tire conditions. In recent years, although the technology has been in progress in the automotive industry, but the number of traffic accidents only to rise to people's lives and property have caused a great threat, the most important reason is that flat tire, in particular, It is traveling at high speed when the car tire pressure will slowly accumulate, to reach a limit of time, prone to puncture.
    In this context, TPMS system came into being, this article will focus on the design for the car - tire explosion-proof system. The real-time system can effectively reflect the current parameters of the various tires, when it reaches an alarm condition, the system will sound and light alarm to alert the driver. At the same time, TPMS there are many problems to be addressed, such versatility, low power consumption and so on. As used herein, a microcontroller-based TPMS program, a prototype system of the program is divided into modules and central monitoring tire pressure detection module, and then complete the hardware configuration.
    First, the article provides a hardware system, and accordingly describes the function and specific circuit design of each module. A brief introduction to its functions and features. Finally, I would principles required by the various components of FIG PROTEUS software debugging and simulation, and make a summary and analysis.
Keywords: TPMS, sensors, microcontrollers, PROTEUS
