摘要： PROBLEM TO BE SOLVED: To provide a method and a system for measuring the wear amount of a trolley wire capable of measuring the wear amount with high accuracy without any handwork while reducing the data processing load for calculating the wear amount. SOLUTION: The average value of the background level on the outer side of a trolley wire sliding surface is calculated on the sliding surface data of one line corresponding to the signal waveform obtained based on the light reception signal, the first reference level higher than the average value and lower than the minimum level of the light reception signal is obtained with the average value being a target, the data of one screen is binarized at the first reference level, and the coordinates of isolated points on the screen corresponding to the noise are extracted. By removing the isolated points from the data for one screen, the sliding surface data for each line with the isolated point noise being removed therefrom is obtained. The width of the sliding surface corresponding to two parameters can be easily calculated to the sliding surface data of one line. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供一种用于测量能够高精度地测量磨损量的电车线的磨损量的方法和系统，而无需任何手动，同时减少用于计算磨损量的数据处理负载。
解决方案：根据基于光接收信号获得的信号波形的一行的滑动面数据计算电车线滑动面外侧的背景电平的平均值，第一参考电平较高以平均值为目标的光接收信号的平均值低于最低电平的情况下，将一个画面的数据以第一基准电平进行二值化，对应于屏幕的隔离点的坐标提取噪声。通过从一个屏幕的数据中去除孤立点，获得了从其中去除了孤立点噪声的每一行的滑动表面数据。对应于两个参数的滑动面的宽度可以容易地计算到一条线的滑动面数据。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a means capable of accurately and easily detecting the positions of supporting points of trolley wires. SOLUTION: A detection system is constructed of an input part for inputting various types of inspection and measurement data collected by a recording coach; a processing part for processing the detection of the positions of supporting points of trolley wires on the basis of the various types of data transmitted from the input part and required parameter files; and an output part for outputting the positions of supporting points on the basis of computation results of the processing part. A detection range R containing the positions of a supporting point is set in a change curve K of inspection and measurement values of displacements of trolley wires to determine a complementary straight line L connecting a point S on the change curve K of inspection and measurement values on the starting side of the detection range R to a point T on the ending side. The distance D P in a direction perpendicular to a track center line C between the change curve K of inspection and measurement values and the complementary straight line L is computed. A reference distance in which the value D P is a maximum value D U is determined. Since the change curve K of inspection and measurement values forms a vertex U at the position of the supporting point, the reference distance is determined as a reference distance X U of a position at which the distance D P is the maximum D U .
