Automatic train protection system and method based on image identification and multi- perception fusion

Abstract

The invention relates to an automatic train protection system and method based on image identification and multi-perception fusion. The automatic train protection system comprises an image collection unit (1), an image processing unit (2), a multi-perception fusion processing unit (3), an auxiliary perception unit (4) and an early warning result output unit (5), wherein the image collection unit (1), the image processing unit (2), the multi-perception fusion processing unit (3) and the early warning result output unit (5) are connected in sequence; the auxiliary perception unit (4) is connected with the multi-perception fusion processing unit (3). Compared with the prior art, the automatic train protection system and method based on image identification and multi-perception fusion can be adapted to complex conditions appearing in urban mass transit operation lines, the safe protection of a train is automatically realized according to the practical condition of a line, and the operation safety of urban mass transit is greatly improved.

Description

technical field [0001] The invention relates to an automatic train protection technology in rail transit, in particular to an automatic train protection system and method based on image recognition and multi-sensory fusion. Background technique [0002] The safety of urban rail transit operation largely depends on the automatic protection system. Usually, in the urban rail transit system, the safety protection between trains (including three situations of head-on, side impact and rear-end collision), train and turnout or other trackside equipment is in the signal automatic control system (Automatic Train Control, below It is realized in the ATC system for short), but the automatic protection of the ATC system is based on track occupancy and active identification and detection of trains. For the intruders that cannot be detected through track occupancy and train active identification during the operation of the urban rail system, the automatic protection of the ATC system ha...

AI Technical Summary

Problems solved by technology

For the intruders that cannot be detected through track occupancy and train active identification during the operation of the urban rail system, the automatic protection of the ATC system has certain limitations.

[0003] For intrusions (obstacles) that cannot be detected through track occupancy and train active identification, such as large rocks or billboards falling on the track, cars across the crossing, people falling into the track, etc., although the There are safety hazards in the operation of urban rail transit, but it is difficult for the ATC system to realize the safety protection of trains
