中文摘要 | This paper introduces an on-line diagnostic function for temperature sensors using a noise analysis approach. The deviation of temperature measurements from their average value is treated as the noise input data, then the noise data is filtered through the Butterworth filter. The power spectrum density estimation of the noise data is obtained by using the Welch method. The first-order characteristic of the temperature sensor is used to obtain the characteristic frequency of the sensor, which can then be used to determine the working status of the sensor. Finally, through a large number of experiments, the results have shown that the sensor's characteristic frequency in a failure condition is significantly higher than that in the normal state. So it verifies the feasibility of on-line diagnosis by using the noise analysis approach for the temperature sensor. |
