铁路是一个对系统设备安全性、可靠性要求很高的行业,列车提速又给铁路安全提出了新的要求,迫切需要建立一套铁路安全标准和评估体系,使得铁路安全管理规范化、标准化、国际化。借鉴国外铁路安全技术和标准,并结合我国铁路行业的实际情况来建立这个体系是比较可行的方法。文章首先对功能安全国际标准IEC61508进行了介绍和分析,然后对该标准在铁路安全相关系统研制、开发和评估过程中的应用进行初步探讨。
Railway is an industry that requires high safety and reliability of system equipment. The speeding up of trains puts forward new requirements for railway safety. Therefore, it is urgent to establish a set of railway safety standards and assessment systems to standardize and standardize railway safety management. The Learn from foreign railway safety technology and standards, combined with the actual situation of China’s railway industry to establish this system is more feasible method. The article first introduced and analyzed the functional safety international standard IEC61508, and then discussed the application of the standard in the research, development and evaluation of the railway safety related system.
