摘　　要：介绍了声表面波传感器测温原理,并设计了一种基于DSP的无线无源温度测量系统.采用具有低通特性的滑动平均数字滤波算法改进了系统的测量精度.通过在某变电站的现场试验,证明了该系统能够有效实现高压开关柜内多点实时探测,具有良好的抗干扰性和稳定性.The principle of SAW temperature sensor is introduced firstly, and then this sensor is used to design a wireless-passive temperature measurement system based on DSP. Moving average digital filtering algorithm with a low-pass characteristics is used to improve the measurement accuracy of the system. Finally, a substation field test proves that the system can effectively achieve multi-point real-time detection in high voltage switchgear with good resistance and stability.
