郑州大学毕业设计（论文） 题目： 机车信号的研究与常见故障分析 指导教师： 职称： 讲师 学生姓名： 学号： 专 业： 电子工程 院（系）： 物理工程学院 完成时间： 2015.5.25 2015年 5月 25日 摘 要 机车信号是指设在司机室内反映列车前方运行条件的信号显示，通常实现机车信号功能的车载设备也被简称为机车信号。机车信号设备是采用高速数字信号处理技术、双套冗余设计的新一代机车信号设备，其主要性能指标符合技术条件，抗干扰性能达到标准，硬件设备符合故障倒向安全的原则。本文针对主体化机车信号在日常检测中出现的机车信号异常情况，全面分析造成机车信号设备故障的各种原因，结合现场维修经验，详细阐述了处理故障的程序和方法、安全注意事项，以利于全面提高机车信号维修质量及职工的故障识别、处理能力，并且本文还特别介绍了一些主体化机车信号机常见故障，针对其设备管理和设备本身两方面进行分析，提出改进措施和方法。 关键词：机车信号 主体化机车信号 设备故障 Abstract Locomotive signal is to point to in indoor reflect the operating condition in front of the train driver, according to the signal usually achieve locomotive signal function of on-board equipment is also referred to as for the locomotive signal.Locomotive signal equipment is to use high speed digital signal processing technology, the double set of redundancy design of a new generation of locomotive signal equipment, its main performance index conforms to the technical conditions, anti-jamming performance reach the standard, the hardware equipment conform to the principle of fault to safety.Based on spatial locomotive signal in the routine detection of locomotive signal abnormalities, a comprehensive analysis of the various reasons of locomotive signal equipment failure, combined with on-site maintenance experience, detailed procedures and methods, and expounds the troubleshooting security considerations, to help improve locomotive maintenance quality and the workers fault recognition, signal processing ability, and this paper also introduces some subjectification specially the locomotive signal common failures, for the two aspects of equipment management and the device itself were analyzed, and put forward the improvement measures and methods.  Key words: the locomotive signal, subjectification locomotive signal, device failure 目 录 第一章 主体化机车信号概述…………………………………………1 第一节 概述……………………………………………………………………1
