摘要

考虑了在线模式下获取机车车辆技术状况可靠信息的问题。已确定,由于使用了一个系统来监测机车车辆的状态参数,从而可以获得此类信息,该系统使用了基于计量支持进行测量的技术手段。众所周知,铁路运输的主要任务之一是交通安全,通过使用参数监测系统来维护和恢复机车车辆的效率、可靠性并降低运营成本,可以确保交通安全。本文介绍了通过计算验证间隔的统计方法提供机车车辆参数测量的计量方面,该方法允许根据可用的初始数据以测量设备的指定误差间隔的形式确定控制误差。该方法的详细描述以及相应地,以图形形式给出了使用该方法来确定平均验证风险的依赖性以及最佳控制公差值的比值对被验证的测量设备的误差估计的依赖性到其允许误差的极限对由于错误和未检测到的故障引起的损失比的依赖性的结果。

METROLOGICAL ASPECTS OF ENSURING MEASUREMENTS IN RAILWAY ROLLING STOCK PROJECTS
The problems of obtaining reliable information in online mode about the technical condition of rolling stock are considered. It was determined that obtaining such information is possible thanks to the use of a system for monitoring the parameters of the condition of the rolling stock using technical means that carry out measurements based on metrological support. It is known that one of the main tasks of railway transport is the safety of traffic, which can be ensured by using a parameter monitoring system to maintain and restore the efficiency, reliability and reduce operational costs of rolling stock. The paper presents the metrological aspects of providing measurements of rolling stock parameters by the statistical method of calculating verification intervals, which allows to determine control errors based on the available initial data in the form of specified error intervals of measuring devices. A detailed description of the method and, accordingly, the results of using the method to determine the dependence of the average risk of verification and the dependence of the ratio of the value of the optimal control tolerance on the estimation of the error of the measuring device being verified to the limit of its permissible error on the ratio of losses due to false and undetected failures are presented, in a graphical form.
