Research and Implementation of a Soft-measuring System for High-temperature Field Based on Color CCD Sensor

A high-temperature-field soft sensing system is developed. The system could online detect the high-temperature fields of high-temperature radiators surface and provide temperature information to operators for analysis and decision. A calibration experiments through black body furnace are adopted to calibrate the soft-measuring system. Multi-spectral segmenting is applied on the image of the high-temperature field, thus various high-temperature noises in the color image can be reduced or even eliminated. The experimental results show that the measurement range of the system could cover the dynamic range of temperature in common high-temperature production. It also has advantages such as high precision, short response time and strong anti-interference ability, which meets the need of the actual industry and has high practicability and promotional value.
