论城轨 ATP 系统工作原理及安全措施毕业论文 摘要: 城市轨道交通列车自动超速防护系统 ATP 自身的作用是保证轨道交通 的行车安全,安全可靠性要求极高，其自身的安全可靠性受到了诸多关注. 本学位论文首先从城市轨道交通列车超速防护系统 ATP 的结构、类型和基本工作原理的分析入手，重点对车载 ATP 系统的可靠性进行了较为深化的讨论。论文结合了南京地铁一号线实际运行的 ATP 系统，简要介绍了这类 ATP 系统的结构和工作原理. 对于车载 ATP 系统，为了能够深化讨论其系统可靠性，计算 ATP 子单元的双机并行暂态和稳态有效度值，以及整个 ATP 系统的稳态有效度。经过实例计算，证明 ATP 系统的有效度高，能够满足安全行车的需求。 本文还提出和分析影响车辆安全运行的具体因素,针对这些具体因素，使用两两比较法，将这些因素对于安全行车影响能力进行排序，并提出相对应的改善策略。最后,根据灾变灰预测理论，预测出同类硬件群体失效率异常的时间段,以便于对 ATP 系统提出合理安排检修的日期.关键词:工作原理； 列车超速防护； 安检Abstract Urban Transit System Automation Train Protection as an important factor to protect train safety. The reliability of Automation Train Protection is asked very high， which to be pay much attention. This theism start at the structure， type and work principle of UrbanTransit Automation Train Protection， and give emphasize to study thereliability of on—board ATP. Introduce structure and work principle of the ATP, which are acting in the number one line of Shenzhen underground. For studying the reliability of on-board ATP farther, Calculate the value of Instantaneous Availability and Steady Availability of ATP' unit which act the end with two same equipment. And calculate the Steady Availability of the whole ATP. After the example calculation ， prove that the reliability of the ATP is very high ， which can satisfy require of train safety. The theism put forward and analyze some factors which influence train safety, to make sure t...
