Embodiment 1

[0042] Such as figure 1 As shown, the train positioning device of the present invention includes: a kilometer sign 4, a train top camera 1, a train side camera 2 and a background server 3, the kilometer sign 4 is installed beside the track, and the train top camera 1 is installed At the top position of the train head, the train side camera 2 is installed at the side position of the train head, and the background server 3 is connected with the train top camera 1 and the train side camera 2 respectively.

[0043] The kilometer signboard is used to mark the kilometer signage information, and the signboard should be made into a trihedron or tetrahedron, which is beneficial to the top and side cameras to capture images;

[0044] The camera on the top of the train is responsible for discovering sign boards and capturing images for identifying sign boards. If it is at low speed, such as only when the train is positioned in the station, the top camera may not be installed;

Abstract

The invention relates to a train positioning device and method. The positioning device comprises a kilometer signboard, a train top camera, a train side face camera and a background server; the kilometer signboard is mounted next to a line track; the train top camera is mounted on the top of a train head of a train, and the train side face camera is mounted on the side face of the train head of the train; and the background server is connected with the train top camera and the train side face camera. Compared with the prior art, based on a convolutional neural network, the train position is determined through image recognition, meanwhile, the train position can be corrected by being matched with an odometer, and the train positioning device is low in mounting and maintenance cost, and hassuperior accuracy and robustness.

Description

technical field [0001] The invention relates to the technical field of train positioning, in particular to a train positioning device and method. Background technique [0002] Train positioning is a key technology of train operation control and plays an important role in rail transit signal system. Real-time and accurate acquisition of train location information is the guarantee for the efficient and safe operation of rail transit, and the prerequisite for improving efficiency and exerting capacity. The train tracking interval is reduced by train positioning, which is conducive to the development of rail transit in the direction of high density and large volume. [0003] Currently commonly used train positioning technologies include: track circuit-based train positioning, transponder-based train positioning, and satellite positioning system-based train positioning. Among them, the train positioning technology based on the track circuit is a coarse-precision positioning met...
