Problems solved by technology

[0008] Although conventional devices have the advantage of using cameras to perform extremely accurate wheel wear measurements, conventional devices disadvantageously have the drawback of requiring additional equipment such as cameras 20-1, 20-2 and light sensors 90
Also, installing cameras 20-1, 20-2 and light sensors 90 on all trains is too expensive, and its durability is not very good
[0009] Another drawback is that the mechanical characteristics may be changed due to the formation of reference grooves on the train wheel used to provide a precise mounting reference point for the train wheel
Yet another drawback is that it is difficult to measure the size of train wheels during train operation, and such use is only possible during maintenance / repair processes to measure the condition of train wheels

Abstract

Provided is a measuring apparatus and method of train wheel wear, the apparatus including a speed measuring unit measuring speed of a train, a position measuring unit measuring a position of the train, and a calculation unit calculating abrasiveness of a train wheel on a train based on the measured speed and position of the train, whereby status of the train wheel can be accurately learned to minimize the number of devices that may be additionally installed, and to quickly measure abrasiveness of the train wheel as well.

Description

technical field [0001] The present disclosure relates to a train wheel wear measuring device and a measuring method, in particular to a measuring device for measuring train wheel wear using a tachometer and a transponder, and a measuring method using the measuring device. Background technique [0002] The information disclosed in this Background of the Invention section is only for enhancement of understanding of the general background of the present disclosure and should not be taken as an acknowledgment or any form of suggestion that the information constitutes a general knowledge base for those skilled in the art. is known prior art. [0003] Due to continuous wear during train operation, train wheels need to be replaced periodically. Therefore, there is a need for a device or method capable of measuring periodic wear and tear of trains. [0004] To measure train wheel wear in CBTC (Communication Based Train Control) based railway signaling systems, equipment such as ca...
