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 that these factors influence ability for train safety, the thesis use two-two compare way to get it. Then put forward corresponding settle way.Finally, in order to arrange rational time for examine and repair,according as Calamities Grey Prediction, prediction the period of time of Failure Rate abnormity.Key words: The Working Principle; Automation Train Protection; Security Check.目 录第1章绪论.3 1.1课题背景. . . 3 1.2国内外现状.4 1.3课题研究的实际意义. 4 1.4论文的结构. 5第2章ATP系统构成和工作原理. 5 2.I ATP系统的功能.5 2.2 ATP系统的结构、分类和工作原理. 6 2.2.1 ATP系统的结构. 6 2.2.2 ATP系统工作的分类. 7 2.2.3点式ATP的工作原理. 8 2.2.4采用轨间电缆的连续式ATP的工作原理. 9 2.2.5采用轨道电路的连续式ATP的工作原理. 9 2.3三种方式的ATP优缺点比较.10 2.3.1点式ATP的优缺点.10 2.3.2采用轨间电缆连续式ATP的优缺点. 11 2.3.3采用轨道电路连续式ATP的优缺点.11第3章列车超速防护.12 3.1轨道交通ATP的“故障安全”准则.13 3.2 列车检测.14 3.3 列车自动限速.,.15 3.4 目标速度和目标距离.16 3.5 制动模式.17 3.6 测速与测距.18 3.7 速度限制.19 3.8 常用制动和紧急制动.15 第4章加强ATP系统安全性的方法. 39 4.1造成不安全行车的因素. 39 4.2加强设备故障预测. 39 4.3提高工作人员的管理和作业能力. 49 4.3.1提高驾驶人员和控制中心人员的工作能力.
