在许多传感器应用的特殊场合,如对电机转子,运动汽车轮胎内,以及一些高温高压等应用场合下的参数测量,如测量温度、压力、应变、振动和加速度等,必须采用无源无线传感方式实现。因此,采用无源无线传感方式实现测量有着广泛的应用前景,而声表面波器件良好的电—声、声—电转换和高效储能特性为其无源无线应用奠定了基础。本文在分析国内外研究成果的基础上,研究了声表面波谐振器的工作原理,建立了应用于温度测量的谐振型无源无线声表面波传感器系统,并就该传感器系统的实用化展开研究。针对国外典型系统中硬件构成复杂的缺点,通过对传感信号的特征分析,提供了一种简单实用的无线收发系统,降低了硬件成本,更适合工业应用需要。由于传感器要适应在不易接触或无法接触的物体内进行参数检测,很多情况下就限制了天线尺寸,因此设计性能良好的电小天线非常重要。本文采用法向模螺旋天线代替以前采用的短偶极子天线以提高效率。为实现远距离测量,提高天线使用效率以及实现天线与声表面波传感器之间的阻抗匹配非常重要。

In many special situations it is necessary to use passive wireless sensors to measure temperature, pressure, stress variation and acceleration in rotors, moving automobile tyres, some high temperature and high voltage situations and so on. Therefore, passive wireless sensing mode has more extensive applications. This paper analyses the operating principle of SAW resonant sensor, builds a passive wireless SAW sensing measurement system applied to temperature detection, and studies on the practicability of the system. Aiming at the complex hardware and the shortcoming that the signal processing unduly depend on hardware, this paper offers a kind of simple and practical transmitter which is cheaper and more adaptive for using in industry. Dimension of the antenna is always limited in non-contact measurement, so designing a high performance small antenna is very important. This paper chooses a normal mode helical antenna to replace the short dipole antenna to improve efficiency. Improving the service efficiency of an antenna and the matching between a small antenna and a SAW sensor is very important for remote measurement.

In many special situations of sensor application, for instance, motor rotor, mobile wheel of car or parameter measuring under high temperature and pressure, such as the measuring of temperature, pressure, strain, vibration and acceleration, it is necessary to employ passive wireless sensors. Hence, measuring which employs passive wireless sensing mode has extensive applications. The electro-acoustic transform and high-performance energy-storage characters of the surface acoustic wave device pave ways to passive wireless applications. This thesis bases on the analysis of the research results home and aboard, researches the operating principle of SAW resonantor, builds a passive wireless SAW sensing measurement system which can be applied to temperature measuring , and studies the practicability of the system. Aiming at the shortcomings of the complex hardware in the image system aboard, , this thesis analyzes the character of sensor signal and offers a simple and practical wireless transmitter, which reduces the hardware cost and fits for the industrial production.. The sensor should be applicable when the parameter measuring of sensor is tested in the non-contactable object, so design of a small antenna with good performance is very important. This paper chooses a normal mode helical antenna to replace the previous short dipole antenna for efficiency improvement. In order to realize remote measuring and improve the service efficiency of an antenna, the impedance matching between a small antenna and a SAW sensor is very important.
