基于卫星遥感技术的输电线路山火风险评估系统 The Risk of Wildfire Evaluation System for Transmission Lines Based on Remote Sensing Technology

研发了输电线路走廊山火风险实时监测与分析系统，提出结合国内外卫星遥感影像数据分析的山火风险评估模型。将该系统成功的应用于湖北电网输电线路山火风险评估，实现了湖北电网范围内的输电线路不同区域的风险分级，应用结果表明，本系统通过互联网技术和卫星遥感，专家系统，大数据挖掘等多重手段，有效的获取了山火风险高发区段，指导了冬春季节的山火预防工作。 In this paper, a real-time monitoring and analysis system for risk of wildfire in transmission line corridor is presented, which has been combined with wildfire risk assessment model based on domestic and international satellite image data. This system has been successfully applied in wild-fire risk assessment for transmission line power grid of Hubei province, which has also realized the classification of risk for different areas in transmission line. The final results have shown that, combined with multiple methods, such as, internet technology, remote sensing technology, expert system and data mining, areas in transmission line with high wildfire risk can be effectively ob-tained by the proposed system, which could be regarded as a guide for fire prevention in the sea-sons of spring and winter.
