摘要
介绍一种符合EN50128-2011的安全数据生成方法,包括2个步骤:数据生成工具的开发和安全数据的生成.数据生成工具的开发采用双链工具法,由2个独立的团队开发,每链工具的开发符合EN50128-2011对SII2软件的开发要求.数据生成过程定义了生成、验证以及确认等活动,每一项活动保证人员的独立性,既避免了安全问题,又提高了配置数据生成的效率.
A method of generating safety critical data in line with EN50128-2011 is introduced,which includes two processes: the development of data generation tools and the generation of safety critical data.The method of double-chain tools are adopted as the tools of data generation which are developed by two independent teams and the development of each chain tool confirms to the requirements of EN50128-2011 SIL2 software.The process of data generation defines the activities like generation,verification and validation and personnel independence of each activity is ensured as well.Thus,safety problems can be avoided and the generation efficiency of configuration data can also be improved greatly.
