摘要:
既有部件用在安全相关的列车运行控制系统之中完成部分系统功能，需要评估其对系统安全性的影响。首先分析既有部件的类型和特点，结合列车运行控制系统安全要求及其证明过程，指出应用既有部件需要解决的问题；然后对系统开发过程中应用既有部件的步骤和安全要求进行分析，提出既有部件的失效控制策略和技术要求；最后分析既有部件安全的证明过程，为基于既有部件的列车运行控制系统安全评估提供建议。
Abstracts:
Safety should be assessed when pre-existing items are used in safety-related train operation control systems as parts of system function. Firstly, the types and characteristics of the pre-existing items are analyzed, with the safety requirements and the demonstration process of the train operation control system, and the problems to be solved in the application of the pre-existing items are identified. Then the application steps and safety requirements of the pre-existing items in the system development process are analyzed, and the failure control strategy and technical requirements of the pre-existing items are suggested. Finally, the safety demonstration process of the pre-existing items is analyzed, and suggestions are put forward for safety assessment of train operation control system based on pre-existing items.
