摘要
汽车轮胎压力监测系统已成为保证汽车安全行驶的重要部分。论述了基于声表面波(SAW)的胎压检测技术,提出了一种基于声表面波技术的胎压检测系统方案,给出了硬件设计框图和软件设计流程。此方案可对行驶中的汽车轮胎的气压和温度进行实时监测,控制爆胎的发生,以保障行车安全。
The tire pressure monitoring system （TPMS） has become an important part in the safe driving. The tire pressure monitoring technology based on surface acoustic wave （SAW） was described in this paper. A tire pressure monitoring system scheme based on SAW technology was proposed and the block diagram of its hardware design and software design were also given. The tire pressure and temperature of the vehicles in driving can be monitored in real-time using this scheme and the tire blowout can be avoided so as to ensure safe driving.
