日本东铁正在发展智能维护理念,通过列车固定检查,连续不断监测线路状态,正在由基于时间维护向状态修转变。有效使用各种检测手段得来的维修数据是“智能维修”理念的核心。自2012年,日本东铁研发中心对此就开展了研究,计划在东京城郊路网中进行初始应用。由于日本社会环境的变化,铁路基础设施和机车车辆的维修体制也将发生很大变化。由于自2011年日本人口开始减少,铁路旅客收入也会随之减少,因此铁路维修费用也会相应减少。但是,信息和通信技术的快速发展,使得使用大数据已成为可能。
Japan’s East Rail is developing its concept of intelligent maintenance. Through train fixed inspection, continuous monitoring of line status is underway from maintenance to maintenance based on time. The effective use of maintenance data from various testing methods is the core of the concept of “intelligent maintenance”. Since 2012, the East Rail Research and Development Center of Japan has carried out research on this and plans to conduct initial applications in the suburban road network in Tokyo. Due to the changes in the social environment in Japan, there will also be a great change in the maintenance system of railway infrastructure and rolling stock. Since the population of Japan began to decrease in 2011, the income of railway passengers will also decrease. Therefore, the railway maintenance costs will be correspondingly reduced. However, the rapid development of information and communication technologies has made it possible to use big data.
