摘要
测量发动机涡轮叶片的最高温度在实际应用中更有意义。因此,本文介绍了一种应用于涡轮叶片温度检测系统中的峰值采样电路设计。峰值点的检测采用了先微分再比较的方法实现。经仿真和实验验证,该检测电路原理设计正确,峰值检测准确,大大减少了在叶片温度测量中的数据存储量,提高了检测系统的实时性。
The measurement of turbine blade＇s maximum temperature is meaningful. This paper introduces a kind of peak-sampling circuits which is used for temperature detecting system of turbine blade and designing the circuits which include operation amplifier （op-amp） and detector parts. The result of the simulation and experiment shows that the circuit is high-quality and accurate and it also makes sure the real-time processing.
