Based on the infrared image processing technology equipment overheating fault source orientation

The traditional electric power equipment overheating fault is done through the artificial detection, can"t do without contact detection, risk is stronger. Combined with infrared thermal imaging theory, the design and implementation based on infrared image processing technology of power equipment overheating fault detection system, introduces the overall structure of the system, through the remote image acquisition module complete electrical equipment within the scope of the infrared image data acquisition and preprocessing, DSP module, which is the core of the infrared image real-time processing equipment, to realize the control and regulation of the whole system. By using FPGA module implements image signal data staging, preprocessing and matching operation. Are analyzed in detail based on the software design of the infrared image segmentation technology and implementation method, and gives a system program implementation code. System test results show that the proposed system has the high feasibility and practicability.#$NLKeywords: infrared image segmentation;Thermal power;positioning
