设计了一种以单色CCD传感器为核心器件的在线监测系统。它可以对变电站的某些电力装置进行近红外探测和在线监测。建立了温度测量模型，分析了影响温度测量的因素，并对温度场进行了计算。通过对辐射设备的监测实验，采集热图像并采用小波去噪算法进行处理。结果表明，该算法检测到的系统最低温度为152℃。
An on-line monitoring system with a monochrome CCD sensor as the key device has been designed. It can detect near-infrared and on-line monitor certain power installations in substations. The temperature measuring model is developed and some influencing factors on the temperature measurement are analyzed and the calculation of the temperature field is made. By monitoring experiment on the radiation equipment, the thermal images are collected and processed by adopting the wavelet denoising algorithm. The result shows that the lowest temperature of the system detected using this algorithm is 152 ℃ .
