随着中国铁路的高速发展,动车组技术的应用,传统的闭塞方式正在由地面固定闭塞朝着车载无线闭塞的方向发展。控制系统也由地面固定设备为主逐渐转换为车载移动设备为主。由此可见,车载设备故障的判定对于保证设备质量、行车安全,有着至关重要的作用。主要介绍由现代系统分析理论引入的故障树分析法在车载设备故障判定中的重要应用。
With the rapid development of China’s railways and the application of EMU technology, the traditional occlusion method is being developed from the ground fixed blocking to the vehicle-mounted wireless occlusion. The control system is also gradually converted from a ground-based stationary equipment to a vehicle-mounted mobile equipment. This shows that the determination of vehicle equipment failure to ensure the quality of equipment, traffic safety, has a crucial role. This paper mainly introduces the important application of fault tree analysis method introduced by modern system analysis theory in the judgment of vehicle equipment failure.
