| Abstract: | 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. |
