摘　　要：铁路提速和行车密度增大造成设备维修作业量不断增加、天窗点时间难以满足铁路维修需求。若存在超时或错点作业时,则会影响维修人员的安全及铁路运营。针对目前铁路现场作业防护中人工瞭望方法效率低、雷达预警误警率高和GPS预警受限于环境条件等问题,提出一种基于差分与光流结合的列车接近预警方法,利用差分法简单快捷和光流准确度高的优势进行列车检测。该方法对现场环境条件要求低,能够准确检测到驶入防护区段的列车并报警。The increase in railway speed and traffic density has resulted in the continuous increase of equipment maintenance operations,the set time is difficult to meet the needs of railway maintenance.If there is an overtime or wrong operation,it will affect the safety of maintenance personnel and railway operations.Aiming at the problems of low efficiency of artificial lookout method,high false alarm rate of radar warning and limited environmental condition of GPS warning in current railway site operation protection,a train approach warning method based on the combination of differential and optical flow is proposed,which uses the advantages of simple and fast differential method and high accuracy of optical flow to detect trains.The method has low requirements on the on-site environment,and can accurately detect the train entering the protected section and alarm.
