In this paper。we discuss XXX discuss the XXX。XXX

Passive SAW pressure sensors operate as either a one-port
delay line with XXX。In the case of a delay line。the interrogator
transmits a burst signal and the sensor responds with a chain of
bursts。one for each XXX delay een two or more response signals

converted into a change in the sensor's surface length or surface
acoustic wave velocity。The delay of the response of a reflector is
determined by the。of the SAW n length on the substrate's surface

absolute pressure values can be measured using simple RF burst
signals。The response impulses are evaluated in magnitude and
phase。and bending the membrane due to pressure load yields a
phase shift of。for instance。100 degrees for 10^4 Pascal。This
allows for the measurement of air pressure in car tires with a n of
approximately 10 Pascal (0.01 Bar)。which can be further ced to

本文介绍了利用声表面波传感器进行轮胎压力监测的应用。
该技术可以通过读取轮胎压力来实时监测车辆的行驶状态。本
文展示了实施原型装置测量轮胎压力的过程,并对声表面波传
感器的应用、改进和安装进行了审讯和讨论。实验结果表明,
该技术在轮胎压力测试期间的游乐设施介绍中表现良好。
经营公路车辆时,运动轮胎的失灵会导致严重的事故,并
危及人的生命。因此,现在的汽车制造商尝试保存备用轮胎的
车辆,即使这样会增加重量和占用空间,但可以降低燃料消耗,
提高收益率。然而,备用轮胎必须在10年以上的汽车生命周
期内使用,因此需要一种可靠的方法来监测轮胎的气压。目前
使用的传感器含有活性成分,使用锂电池,造成约20克的高
动态负载。几年前,声表面波传感器被发明用于传感器应用。
它们是无源器件,不需要电力供应或半导体,并且可以测量温
度、机械负荷、力和位移等。在车辆强烈的电磁干扰下,声表
面波传感器具有更长的寿命和更高的可靠性。
首先,我们讨论压力测量采用声表面波传感器与无线传感
器组件和审讯的实施。电气行为被动声表面波压力传感器始终

最后,我们介绍了一个原型,用于实验的压力商会与膜制
成的传感器安装单位的枢纽第连接阀门的压力大会。该传感器
可以实现无线测量,并且可以在汽车轮胎中使用以监测气压。
本文介绍了无线声表面波传感器在汽车系统中测量轮胎压
力的应用。该传感器具有免费维修和承受较高的热和机械载荷
测量性能媲美的优点。与传统的SAW传感器相比,该传感器
具有更高的鉴定精度。在应用中,该传感器的低离心力可以减
少动态力学负荷,使其适用于旋转部分。此外,该传感器的质
量仅为20克,集成了压力传感器本身,因此可以大规模应用
于轮胎压力测量。在一些系统中,由于电池不能被选中,传感
器应改为太多,导致废物系统和收益率问题。因此,只有故障
应该触发系统的显示屏可以被取消,降低了系统的成本。
综上所述,无源声表面波传感器在车辆测量轮胎压力方面
具有优越性。它不仅适用于低质量的事实,而且免费维修。因
此,它比声表面波传感器的压力测量更具优势。在实施轮胎和
系统为了审讯结果了大量的测量提出了游乐设施。参考文献包
