System and method using GPS+ wheel diameter to derive one-pole-one-gear data

Abstract

The invention provides a system and method using GPS+ wheel diameter to derive one-pole-one-gear data; the system comprises support poles, a signal trigger, a wheel diameter pulse gatherer, and a GPSinformation gatherer; the signal trigger is mounted on a vehicle, and a signal is triggered when the vehicle passes the support pole; the system obtains the signal, and gathers GPS and wheel diameterpulse data; the wheel diameter pulse gatherer is mounted on the vehicle wheel, and used for accumulating and counting wheel rotating numbers; the GPS information gatherer is mounted on the vehicle soas to gather GPS data; the signal trigger, the wheel diameter pulse gatherer, and the GPS information gatherer are in communication connection. Compared with the pour wheel diameter or GYK in the prior art, the system and method using GPS+ wheel diameter to derive one-pole-one-gear data are higher in precision, and more accurate in positioning.

Description

technical field [0001] The invention relates to the technical field of high-speed railway detection, and in particular to a system and method for deriving data of one bar and one gear by adding a wheel diameter to GPS. Background technique [0002] Catenary suspension state detection and monitoring device (referred to as 4C system) is a set of intelligent detection system for catenary faults applied to electrified railways. One lever and one gear are the key functions in railway 4C intelligent detection. [0003] The 4C intelligent detection system detects the operation of the train on the railway, uses high-definition industrial cameras to take pictures of various parts, and then analyzes the pictures to detect the faults of electrified railway related equipment such as columns and catenary in the line. [0004] For fault location, recording and maintenance, it is necessary to uniquely confirm the column information corresponding to each monitored data, that is: which colum...

Problems solved by technology

[0009] In the technology of calculating the driving distance based on the detected wheel diameter encoder, combined with manual participation in setting and correction for positioning, the wheel diameter changes due to the long-term operation of the detection vehicle, wheel slipping and idling during driving, and the span of the basic railway data itself The error and other factors lead to calculation errors, and the farther the driving distance, the greater the calculation error, resulting in the need for continuous manual correction throughout the detection process, resulting in a large workload;

[0010] In the technology of manually checking the pole number, and then querying the corresponding information through the pole number to locate, there is a manual method that takes too long and cannot meet the needs of the 4C detection system;

[0011] In the positioning technology using the pole number recognition technology, due to various reasons such as uneven illumination, occlusion, and damage to the pole number plate, the correct pole number identification cannot be performed
