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

The present invention provides a train wheel wear measurement device and a measurement method, the device comprises: a speed measurement unit, which measures the speed of the train; a position measurement unit, which measures the position of the train; and a calculation unit, which measures the The speed and position of the train are used to calculate the degree of wear of the train wheels on the train, so that the condition of the train wheels can be accurately known to minimize the number of additional equipment that may be installed, and the wear of the train wheels can also be quickly measured Spend.
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 disclosure and should not be taken as an acknowledgement, or any form of suggestion, that this information forms the basis for those skilled in the art is known prior art. [0003] Due to continuous wear and tear during train operation, train wheels need to be replaced periodically. Therefore, there is a need for an apparatus or method capable of measuring the periodic wear of a train. [0004] To measure train wheel wear in a CBTC (Communication Based Train Control) based railway signaling system, devices such as cameras and light se...
