为了克服智能变电站温度检测环境复杂、非接触、精度低、成本高的缺点,研究并开发了一款无源无线声表面波智能温度传感器;研究了该型温度传感器的检测机理,并研究了无源无线声表面波智能传感器收发系统;设计了传感器系统射频模块匹配电路,并对输入输出信号进行了Multism仿真;基于无源无线声表面波传感器构建了智能变电站温度检测系统;现场试验发现系统温度精度提高了10%以上,长期运行无故障,表明该无源无线声表面波温度传感器在智能变电站测温中具有优异的表现,具有较广的应用前景。

To overcome the high complexity, non-contact, Low sensitivity and the high cost of the temperature monitoring environment in the intelligent substation, a smart passive wireless SAW (Surface Acoustic Wave) temperature sensor has been studied and fabricated. The wireless transceiver system architecture and the Sensing mechanism of the SAW sensor have been studied. The matching circuit of the SAW sensor RF module is also designed. The Multism simulation of the input and output of the matching circuit is proposed too. An intelligent Substation temperature detection system is built on the smart passive wireless SAW temperature sensors. The use of the passive wireless SAW temperature sensor in the temperature mo...
