摘要
本文主要介绍了用于列车控制等信号系统设计过程中的风险管理技术,着重描述了风险的概念和分析的过程,并介绍了依据欧洲铁路标准EN50126中风险分析的要求,具体对联锁系统的安全通信子系统进行了风险分析实践的描述。
This paper describes the safety management technology applied in the development process of safety-critical train control system, focusing on the concept of risk and process for risk analysis. In compliance with EN50126 requirements, the paper also describes how the process has been applied in the development of a communication sub-system of an interlocking product.
