Problems solved by technology

The high-density laying of transponders is expensive, and some lines do not have track circuits, so it is impossible to lay out transponders
[0005] The existing technology identifies the data information of the pole number plate and the timing when the train passes the pole number plate by identifying and analyzing the logo image beside the track, and uses this to locate and correct the train position. However, because the speed of the train is fast, In addition, it is necessary to continuously identify the content of the pole number plate, and it is possible to miss a certain pole number plate so that the recognition error will eventually lead to the problem of positioning errors

Embodiment Construction

[0055] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0056] The existing technology identifies the data information of the pole number plate and the timing of the train passing the pole number plate by identifying and analyzing the logo image beside the track, and uses this to locate and correct the train position. However, because the train speed is fast, In addition, it is necessary to continuously identify the content of the pole number plate, and it is possible to miss a certain pole number plate so that the recognition is wrong, which eventually leads to the problem of positioning errors.

Abstract

The invention discloses a continuous identification and correction device and method for a track pole number plate content, which relates to the technical field of train positioning. The device comprises a carriage, an image acquisition device, an image processing device and a display device, wherein the image acquisition device is connected with the image processing device; the image processing device is connected with the display device. By judging the number of the wire poles in the image, when the number of the wire poles is large, the optimal wire pole is selected to be recognized, then the pole number on the optimal wire pole is recognized, then the continuous pole number is corrected, and the accurate pole number is obtained.

Description

technical field [0001] The invention relates to the technical field of train positioning, in particular to a device and method for continuously identifying and correcting the content of a track pole number plate. 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 technolo...
