Problems solved by technology

[0005] 1. The communication rate is low. Currently, the update frequency with the train location information system is 5Hz, and the timeliness affects the positioning accuracy;
[0006] 2. There is a positioning error in the train position information itself, and this error will continue to accumulate, so that the longer the section line, the greater the error as it goes to the back;

Abstract

The invention discloses a straddle type monorail finger-shaped plate recognition and positioning method and system. The method comprises the steps of collecting an image of a PC track beam; performing image morphological processing and feature extraction on the image, and identifying a finger-shaped plate in the image; determining a PC track beam number correspondingly associated with the finger-shaped plate from a preset finger-shaped plate database; and taking the PC track beam number as positioning information of the finger-shaped plate and outputting the positioning information. According to the straddle type monorail finger-shaped plate recognition and positioning method and system, the finger-shaped plate on the PC track beam is recognized in real time, and the finger-shaped plate is associated with the PC track beam number, so that the positioning precision is improved, and maintainers can be better guided to carry out maintenance.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a method and system for identifying and locating straddle-type monorail finger plates. Background technique [0002] The straddle-type monorail is a means of transportation guided and supported by a single track. Its car body rides on the PC track beam and uses high-voltage electricity as the power source. Strong slope ability and other advantages. The straddle-type monorail is low in cost, small in space, light and flexible, and is more suitable for laying in cities with complex terrain and dense population. [0003] The finger plate is a metal part that connects two adjacent sections of the monorail body in the straddle monorail to ensure that the train wheels pass through the PC track beam safely and smoothly. After the straddle-type monorail is put into operation, the state of the finger plate will change as time goes by, which will have a great impact on the operat...
