摘　　要：电晕放电一直是大型发电机安全运行的重要威胁之一。通过巡检机器人可以有效的避免传统人工巡检的弊端。为了高效检测电晕的发生,本文对轨道式巡检机器人搭载的各项传感器的传感数据进行处理,通过Logistic回归结合随机梯度上升法估计各项传感参数的回归系数,得到综合传感信息指标,进而判断电晕的发生以及严重程度,提高了检测的准确性。Corona discharge is one of the important threats to the safe operation of large generators.Through the inspection robot can effectively avoid the disadvantages of traditional manual inspection.In order to effectively detect the occurrence of corona,this paper deals with the sensor data of the sensors on the track inspection robot.The regression coefficient of each sensing parameter is estimated by logistic regression combined with random gradient rise method,and the comprehensive sensing information index is obtained,then the occurrence and severity of corona are judged,and the accuracy of detection is improved.
