Abstract

The invention discloses an obstacle recognition method, an obstacle recognition system and a rail car automatic driving device. According to the method, whether an obstacle influencing operation of the rail car exists or not is determined according to image information of a rail area in front of the rail car, and when an obstacle influencing operation of the rail car exists in a front rail area, corresponding braking early warning information is sent out according to the safety braking distance of the rail car and the distance between the rail car and the obstacle. Therefore, distance measurement and early warning of obstacles in front of the operation of the rail car can be realized for driving control. Meanwhile, the automatic driving device for the rail car can acquire image informationof a rail area in front of the rail car in real time; and the obstacle in front of the operation of the rail car is automatically identified, early warned and controlled to drive according to the image information, so that the driving efficiency and the driving safety are effectively improved, the energy consumption is reduced, the operation and maintenance cost is reduced, the working intensityof a driver is greatly reduced, and a technical guarantee is provided for the safe operation of the rail car.

Description

technical field [0001] The invention relates to the technical field of railcar control, in particular to an obstacle recognition method, an obstacle recognition system and a railcar automatic driving device. Background technique [0002] In the prior art, railcars usually use a vehicle-mounted video monitoring system to capture video images for assisting drivers in operations, and store video data for later viewing. In order to improve efficiency and safety, reduce energy consumption, reduce operation and maintenance costs, and improve labor intensity, automatic driving of rail cars has become an internal demand for the development of my country's railway technology, and is an important symbol of the intelligentization of rail car train control systems. However, the existing independent on-board video monitoring system cannot realize ranging, early warning and driving control of obstacles in front of the rail car, thus restricting the development of rail car automatic drivin...
