Abstract

The invention discloses a railway vehicle active obstacle and derailment detection system, which includes an obstacle and railway detection unit, a data processing unit and a train control system which are electrically connected mutually. The obstacle and railway detection unit are used for scanning objects around the railway vehicle and a running railway during driving, and obtaining object point cloud data, object information and track image information, in the data processing unit, initial point cloud data, initial image information and initial track image information obtained by a camera of objects around the railway vehicle obtained by the radar in the normal driving process are pre-stored, a result is analyzed and fed back to the train control system by integrating and comparing information fed back by the obstacle and railway detection unit with memory information of the obstacle and railway detection unit, and according to the analysis result, the train control system gives control instructions to the train running state actively. According to the way, the railway vehicle active obstacle and derailment detection system can find abnormalities in time and give active braking instructions to the vehicle.

Description

technical field [0001] The invention relates to the technical field of autonomous driving of rail vehicles, in particular to an active obstacle and derailment detection system for rail vehicles. Background technique [0002] Rail vehicles have the characteristics of large transportation volume, low energy consumption, high safety, convenience, and all-weather transportation. Many countries in the world regard rail vehicles as very important basic transportation facilities. At the same time, with the development of urban rail transit technology, some large cities at home and abroad have proposed to build fully automatic driverless rail vehicles to improve operating efficiency. Considering the high speed and high inertia of rail vehicles during operation, and the relatively complex road conditions in rail transportation, the obstacle and derailment detection technology of rail vehicles has become one of the research hotspots in the field of rail transportation automation.
