首页国际标准 En50129
这个标准定义了为了保证安全相关的铁路信号电子系统/子系统/设备安全所必须满足的条件.这些条件包括: 质量管理措施 安全管理措施 功能和技术安全措施 安全接受和论证 作为一个安全相关系统要作到系统的安全能够得到接受和论证,必须经过前三个步骤. EN 50129就是针对一个安全事例来指导系统研究开发人员在整个系统 图2-3 "V"安全设计周期 研制开发生命周期内所要完成的质量管理,安全管理和相关的技术安全措施的实施.对于安全管理,引入IEC61508提出的安全生命周期概念,就是说对于安全相关系统的安全部分,在设计时按照该步骤进行设计,并且需要进行全程的安全评估和验证,目的是进一步减少和安全相关的人为失误,进而减少系统故障风险.图2-3将系统各个层次的开发和评估论证对应起来,描述的是"V"字型系统安全生命周期.
