本科毕业论文(设计) 基于无线通信的轮胎压力监测系统的设计系(部) 电气工程系专业测控技术与仪器学号学生姓名指导教师提交日期年月日中工信商 20 15- I 摘要数据显示,国内高速公路交通事故有 42% 以上的是由于轮胎故障引起,其中爆胎引起事故占事故总量的 80% 之多,由此数据显示不难看出!轮胎压力监测系统( tire pressure monitoring system )是避免事故的重要保障之一。在汽车电子技术高速发展的前提下,目前国内采用的胎压检测系统主要分为两种类型: 间接式的胎压监测系统和直接式胎压监测系统。本设计深入分析了 TPMS 研究现状和发展趋势,对比了间接式的胎压监测系统与直接式胎压监测系统的优缺点, 选择直接式 TPMS 作为本设计的研究课题。本设计将通过在轮胎内部安装实时温度、压力监测模块,通过微处理器处理后,经过无线通信技术,发送至中央监视器,实时显示轮胎温度、压力值。当出现异常情况时能及时发出报警信息。关键字: 直接式,温度传感器,压力传感器,报警,无线通信 II Abstract According to statistics, in China, 46% of the highway traffic accidents are caused by faulty tyres, the flat tire a alone accounted for 70% of total accidents, the Numbers how amazing it is! Tire pressure monitoring system ( tire pressure monitoring system) TPMS isone of the important guarantee for safety. On the premise of automobile electronic technology high speed development, the current domestic use of tire pressure detection system is mainly divided into two types: indirect tire pressure monitoring system and direct tire pressure monitoring system. This design of TPMS research status and development trend were analyzed, pared the indirect tire pressure monitoring system and the advantages and disadvantages of direct tire pressure monitoring system, direct TPMS is chosen as the research topic of this design. This design will be sent to you by installed inside the tire pressure and temperature sensor, the temperature inside the tire in the central control unit, the pressure value after the acquisition, processing through the wireless way to send data to monitor in the middle of the cabin interior. The central monitor to analyze the data of the tire, and the pressure value through wireless transmission way to return to the cockpit, real-time display on the LCD screen, when the abnormal situation can send out alarm information ina timely manner.
