【摘要】：近年来，随着我国各个方面的快速和稳健的发展，我国的铁路运输行业质量也得到了迅猛的提升，目前我国更是将铁路行业的发展列入我国最新的发展战略当中。铁路运行速度多次提升，高铁的建设全面铺开，铁路行业的技术水平已经达到了世界领先水平，已经将我国的很多先进技术推向了国外。但是，我国也有自己的铁路运输的特殊问题，我国是人口大国，，工业大国，铁路运输是我国目前最重要的一个运输方法，承载着运输人员、物流中转、工业原材料运输等多项工作。随着人民生活水平和文化水平的提高，人们出行旅游的频率不断的增加，此外，物流行业的迅猛发展，也为铁路运输增加了很多负担。铁路信号设备是铁路正常运行的关键部分，是列车安全运行的保障。那么如何及时的发现设备故障，如何采用新的故障检测技术，以及如何采用新的故障检测设备，并结合完善的故障分析方法来进行故障检修是目前的研究热点。迅速的发现故障、修复故障、排除故障，以及对铁路的各个信号设备状态进行监控和检测是铁路运输部门最主要的研究工作，也是保证我国铁路安全运行的基础。目前，我国铁路的各种信号设备都已经不断的更新、改革、完善和现代化；维修制度也在不断的完善；维修人员的素质也不断的提高。总的来说，我国铁路的信号设备的维修质量和维修水平已经得到了巨大的提升，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、铁路运输各种信号的多样性、铁路运行环境的复杂性，造成铁路信号设备故障的原因也具有随机性、多样性、复杂性，这些都对铁路信号设备的及时检修提出了更高的要求，要求铁路信号设备的维修要具有实效性，要有快速反应机制，除了要对铁路的信号设备的质量有较高的要求，对铁路部门的检修速度和检修时间也都提出了要求。由于铁路信号设备很多，具有显示、控制和报警等功能，检测方法又具有十分复杂的特点，承担着整个列车运行的指挥工作和保证铁路运行通畅的工作。如果不及时其进行检修，轻则会造成列车的晚点，重则打乱了铁路的运行秩序，造成重大事故和人员伤亡，因此单纯依赖人工进行检测已经不适应目前的发展趋势。综上所述，我国目前的铁路运输行业，迫切要求开发一个铁路专家故障诊断的系统从而能够对现场采集的数据进行实时的分析、及时的发现故障和及时的对设备故障进行诊断，本文主要根据铁路日常信号设备发生故障的各种类型、故障的原因、故障的一般解决方案来设计的专家故障诊断系统，首先系统可以根据大量的历史数据进行前期分析进而预警，以免产生故障，也可以为维护人员提供可靠的历史数据，然后系统运用专家诊断方法对铁路运行过程中的故障问题进行分析来确定故障的发生位置，并能及时提供最合适的检修方法，及时以报表工单的形式报送给检修人员，大大的提高了故障诊断和检修的效率，系统由多个子模块组成，主要有铁路信号设备检测的历史数据模块、故障原理的分析模块、报表分析模块组成，此外本文对各种推理规则和诊断方法进行了详细的介绍，并举例说明专家系统的一个具体应用过程，能为铁路运行中的信号设备故障提供准确的分析，并及时的给予正确的处理方案，以便使读者更好的进行理解，并对目前还存在的一些不足进行了总结和展望。
[Abstract]:In recent years, with the rapid and steady development of all aspects of our country, the quality of our railway transportation industry has also been improved rapidly. At present, the development of the railway industry is included in our country's latest development strategy. The speed of railway operation has been promoted many times, the construction of high speed rail has been completely opened, and the technical level of the railway industry has already been developed. It has reached the world's leading level and has pushed many advanced technologies of our country to foreign countries. However, China also has its own special problems of railway transportation. China is a large population, an industrial country, and railway transportation is the most important transportation method in our country at present, bearing the transportation and transportation personnel, the transfer of logistics, the transportation of industrial raw materials and so on. With the improvement of the people's living standard and the cultural level, the frequency of travel travel has increased continuously. In addition, the rapid development of the logistics industry has also added a lot of burden to railway transportation.
The railway signal equipment is the key part of the normal operation of the railway and the guarantee of the safe operation of the train. Then how to find the equipment fault in time, how to adopt the new fault detection technology, how to adopt the new fault detection equipment, and combine the perfect fault analysis method to carry out the troubleshooting are the hot spots at present. It is the most important research work of railway transportation department to find fault, repair fault, eliminate fault and monitor and detect the state of railway signal equipment. It is also the basis of ensuring the safe operation of railway in China. At present, all kinds of railway signal equipment in China have been constantly updated, reform, perfect and modernized; maintenance system In general, the maintenance quality and maintenance level of the railway signal equipment have been greatly improved. However, with the increasing number of railway passenger lines in China, the speed of railway transportation is continuously improved, the railway transportation signal equipment is gradually increasing, and the railway transportation signal equipment is gradually increasing. The diversity of all kinds of signals and the complexity of railway operating environment cause the causes of railway signal equipment failure also have randomness, diversity and complexity. These all put forward higher requirements for the timely maintenance of railway signal equipment. It requires the maintenance of railway signal equipment to be effective and there should be a rapid response mechanism, in addition to the The quality of the railway signal equipment has high requirements, and the maintenance speed and maintenance time of the railway department are also required. Because of many railway signal equipment, it has the functions of display, control and alarm, and the detection method has very complicated characteristics. It bears the command work of the whole train operation and ensures the smooth running of the railway. If it is not repaired in time, the light will cause the delay of the train, the weight of the train will disrupt the operation order of the railway, cause major accidents and casualties, so it is not suitable for the current development trend to rely solely on manual testing.
To sum up, the current railway transportation industry in our country is urgent to develop a system of fault diagnosis of railway experts so that the data collected in the field can be analyzed in real time, the fault is found in time and the fault of the equipment is diagnosed in time. This paper mainly based on various types of fault of railway daily signal equipment and fault. The expert fault diagnosis system is designed by the general solution of the fault. First, the system can be analyzed and then early-warning based on a large number of historical data, so as to avoid failure and provide reliable historical data for the maintenance personnel, and then the system applies expert diagnosis method to the fault in the railway operation process. Line analysis to determine the location of the fault, and can provide the most appropriate maintenance methods in time, timely delivery to the maintenance personnel in the form of report form, greatly improving the efficiency of fault diagnosis and maintenance, the system is composed of multiple sub modules, mainly the historical data module of railway signal equipment inspection, the analysis module of fault principle, In addition, this paper introduces various reasoning rules and diagnostic methods in detail, and illustrates a specific application process of the expert system, which can provide accurate analysis for the fault of the signal equipment in railway operation, and give the correct solution in time so that the reader can understand better. Some shortcomings are also summarized and prospected.
