Problems solved by technology

However, this method has obvious shortcomings, that is, it cannot realize early detection and early warning of obstacles in the track in the direction of the train, and improve driving safety. On the other hand, the detection of obstacles through mechanical collisions will inevitably cause damage to vehicle equipment.
[0004] In the prior art, remote obstacles within a certain angle range in front of the train are also detected by machine vision or lase

Embodiment Construction

[0058] The present invention will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0059] figure 2 A structural diagram of an unmanned foreign object detection system according to an exemplary embodiment of the present invention is shown. Such as figure 2 As shown, the system includes a track detection unit 100 , an obstacle detection unit 200 , a radar detection unit 300 and a main control unit 400 . The system is usually installed at the head of the train.

[0060] The track detection unit 100 takes a track image, and demarcates an effective detection area by...

Abstract

The invention discloses an unmanned driving foreign matter detection system and method. The system comprises a track detection unit for shooting a track image and calibrating an effective detection area by tracking a track path in real time on the track image, an obstacle detection unit for shooting an image in front of a train in operation and identifying an obstacle through comparison with a standard track environment image, a radar detection unit for positioning a distance between the obstacle identified by the obstacle detection unit and the train, and a main control unit for carrying outgrading alarm on a train control center based on a detection result and providing a visual image of the obstacle. According to the detection system and method, multiple sensor technologies are fused for detection; a visual sensing device is used for replacing a driver to continuously see towards the front of the running train; obstacle features are extracted through an image identification technology, and the obstacle is positioned through a radar; and the obstacle can be detected and identified remotely, so that the response time is provided for early warning vehicle control and fault checking.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an unmanned foreign object detection system and method. Background technique [0002] There are many underground tunnels in the subway environment, and the space is narrow and closed. The cables, bridges, pipelines, and electrical boxes on both sides of the tunnel may fall off and cause intrusion. Among them, abnormal phenomena such as obstacles on the rail surface, rockfall in the tunnel, and people falling pose a threat to driving safety. Serious, if it is not detected and dealt with in time, it is likely to cause serious accidents. [0003] At present, an obstacle detection system based on the principle of mechanical trigger is installed under the head of the train to replace the driver's function of looking at the line ahead. The travel rod moves, and then triggers the relay switch circuit, so that the train is stopped in an emergency. However, this method has o...
