摘要
安全完整性是安全相关系统实现其安全功能的能力。明确的安全完整性需求及适当的分配,有利于提高铁路信号产品的安全性。从安全完整性概念出发,介绍了可行的铁路信号产品安全完整性需求的确定以及分配方法。对于安全相关产品的开发有着至关重要的作用。
Safety integrity indicated the ability of safety related system to achieve their critical functions.Proper definition and explicit allocation of safety integrity requirements can facilitate improving the safety of the railway signal systems.The paper gives a feasible method to determine and allocate the safety integrity requirements of railway signal systems,which is important to the development of safety-related products.
