铁路信号设备故障诊断系统设计

摘要随着中国的发展越来越迅速、人们的生活水平的提高，人们的出行和运输也越来越多，人们对速度与安全要求也越来越高。现今中国的发展速度随着人们的要求，也在不断加快，但是随着我国铁路客运线路不断的增多、铁路运输的速度不断的提升、铁路运输信号设备逐渐增加，对于运输一大主要方式‘高速铁路’的关注度也越来越高，安全问题也被越来越重视，那么铁路设备故障安全系统的重要性就不言而喻了。本论文研究故障诊断技术的目的就是保障行车安全，防患于未然。69873

铁路设备故障诊断系统的任务是诊断铁路信号设备故障，系统要及时发现故障，反映故障并下达给维修人员如何最好的解决故障。本文先系统地学习了铁路信号设备系统的知识，然后深入的探索了各类故障的现象，产生原因及解决方法。掌握了这些基本的铁路知识了之后，本论文系统的学习了铁路故障诊断系统的两大先进系统：故障树系统和专家系统，分析了它们的优点也得知了它们固有缺点，将这两个系统加以融合、互补，最终论文融合出了一个新的故障诊断系统。

Design of fault Diagnosis System for Railway Signal Equipment

Abstract As China develops more rapidly, improving people's living standards, people's travel and transport is also more and more people on the speed and safety requirements are also increasing . Today China's pace of development with the requirements of the people, but also continues to accelerate, but with China's railway passenger line continues to increase, the speed of rail transport constantly upgrading the railway signaling equipment transport increasing , for one of the main transport by 'high-speed rail' increasingly high degree of concern, security issues have also been more and more attention, the importance of railway equipment fail-safe systems becomes evident. The purpose of this paper is to study fault diagnosis ensure traffic safety and take preventive measures.

Task railway equipment fault diagnosis system is the railway signal equipment failure diagnostic system to detect faults, reflect the fault and issued to service personnel on how best to solve the problem.

This article first systematic study of knowledge of railway signaling systems, and in-depth exploration of the phenomenon of various types of faults, causes and solutions. Mastered these basic knowledge of the railway after this paper studied the railway system fault diagnosis system of two advanced systems: fault trees and expert systems, and analyzes their advantages and that their inherent shortcomings, these two system integration to be complementary, the final integration of the paper, a new fault diagnosis system.

Key Words: railway signaling equipment failure fault diagnosis system
