【摘要】 汽车轮胎安全在汽车安全行驶中起着重要作用。文中介绍了汽车轮胎安全监测系统课题的研究背景、国内外研究现状。给出一种载货汽车轮胎安全监测系统的实现方案。系统基于无线传感器网络设计,通过安装在每个汽车轮辋上的无线传感器网络节点采集胎压、温度数据发射;网关节点接收数据转发至主控中心;主控中心对数据分析处理,若不在安全范围,发出声、光等信号报警,提醒驾驶人员采取防范措施,同时将数据通过GPRS网络上传至远程数据中心,以实现远程监测。系统无线传感器网络节点采用集成有A/D及RF收发器的低功耗无线单片机CC2510,3.6V锂亚电池供电。系统软件采用嵌入式C语言设计,开发平台为IAR7.20H、Keil uVision3、μC/OS-II操作系统,文中分别给出通信协议及各部分相关的软件流程图。本课题来源于企业,目前已结题验收。课题创新点:设计了一种基于无线传感器网络的汽车轮胎安全监测方法,填补了国内载货汽车轮胎(有胆胎)安全监测产品的空白。附录给出了系统相关的电路原理图、实物图像及安装图像。更多还原

【Abstract】 Tire safety of automobile Tires plays an important role in vehicles safe driving. This dissertation firstly introduces the research background and the research status at home and abroad, and then the realization scheme of automobile tire safety monitoring system is proposed.The monitor system is designed based on the wireless sensor network (WSN) , the tire pressure and the brake drum temperature data are acquired by the WSN nodes which are installed on each tire’s rim. The gateway nodes receive the data which is transmitted by WSN nodes and transmit to the control center. The data is analyzed and processed by control center, if it is out of the safe scope the control center will make some alarm signals such as sound, light, etc. to remind the driver take some measures. At the same time the control center will send the data to the remote data center through GPRS net. The low power wireless MCU CC2510 which is embedded an A/D converter and RF transceiver is used to be as the microcontroller of the WSN nodes and its power supplied by the 3.6V lithium battery. The embedded C language is used to develop the system software, and the software platforms are as follows: IAR7.20H, Keil uVision3,μC/OS-II embedded operating system. This dissertation presents the communication protocol and the relevant software flow charts respectively.This subject derives from company, now it has been checked and accepted. The innovations of the subject are as follows:a kind of method about tire safety monitoring system for automobile based on WSN is proposed, and it fills the domestic gap in the field of truck tire security monitoring production.Appendix is to offer some diagrams about the system such as schematic diagrams, instance diagrams and installation diagrams.更多还原
