Embodiment

[0050] The present invention mainly relates to the multi-sensory fusion technology of image recognition, and its basic structure diagram is shown in figure 1 As shown: 1 in the figure is the image acquisition unit, 2 is the image processing unit, 3 is the multi-sensory fusion processing unit, 4 is the auxiliary perception unit, and 5 is the early warning result output unit.

[0051] In the present invention:

[0052] The image acquisition unit 1 can be a CCD camera, an infrared camera at night or other cameras in accordance with the usage scene of the present invention, mainly collects image resources of the surrounding operating environment of the train in real time, and then transmits the image signal to the image processing unit 2 through the video synchronization separation chip .

[0053] The image processing unit 2 is the core processing unit for image recognition, which mainly extracts and recognizes the feature data of unsafe elements in the surrounding operating envi...

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...
