Abstract

The invention discloses a rail unmanned obstacle identification method. The rail unmanned obstacle identification method comprises the following steps of installing radars on the front and rear portions of a flaw detection vehicle and conducting obstacle detection on advancing and retreating orientations of the flaw detection vehicle; partitioning the advancing or retreating orientation of the flaw detection vehicle into an attention area, an early warning area and a warning area; detecting the moving direction of the flaw detection vehicle and selecting the radar; judging the state of whetherthe flaw detection vehicle shuts down an anti-collision system of the flaw detection vehicle; and judging the actual vehicle speed of a vehicle body and conducting processing. Through the rail unmanned obstacle identification method, the radars are mounted on the front and rear portion of the flaw detection vehicle to ensure the safe no-blind areas, real-time monitoring and no time blind spots, the monitoring areas are partitioned clearly to ensure the speed reduction and parking areas, and the distance is rationally planned; the radar to be used is selected according to the moving directionof the flaw detection vehicle, misjudgment is reduced, and the error rate is lowered; when an obstacle is removed, the vehicle body automatically restores to the original state. The rail unmanned obstacle identification method has the intelligence characteristics, reduces the operating time and workload of staff and has the characteristics of high efficiency, high safety and high accuracy.

Description

technical field [0001] The invention belongs to the technical field of obstacle identification, and relates to an obstacle identification method for track unmanned driving. Background technique [0002] At present, rail flaw detection mainly relies on hand-push flaw detection instruments and double-track flaw detection trolleys, and mainly relies on manpower to complete the work. Due to the different experience of personnel, experienced old technicians can effectively judge obstacles and the distance of obstacles, according to obstacles and The distance of obstacles can judge the danger, but for inexperienced personnel, there is a problem of poor accuracy in judging obstacles. At the same time, due to human factors and detection blind spots, the accuracy of obstacle recognition is poor and the safety is low. In order to solve the above problems, an obstacle recognition method for track unmanned driving is designed. Contents of the invention [0003] The object of the pres...
