摘要
牵引控制系统软件的安全性和可靠性是列车稳定运行的重要因素之一,对其进行安全完整性设计和评估是有必要的。以列车牵引控制系统软件产品的安全认证为例,结合EN 50128:2011标准,对牵引控制系统软件安全完整性评估的技术以及实现方法进行深入研究和实践应用,重点描述依据生命周期流程开展软件设计和软件测试的认证工作,并根据第三方评估机构对整个工作进行总结评估,可为城市轨道交通软件产品的安全认证提供参考依据和借鉴。
The safety and reliability of drive control unit is one of the important factors for the train stable operation, which should be designed and evaluated in safety integrity. Taking the drive control unit software safety certification as an example, and combining with EN 50128:2011 standard, in-depth study and practical application on the technology and implementation method of safety integrity assessment were carried out. Focusing on the activities of design and test certification based on the life cycle process, the whole work according to the third-party assessment organization was summarized, which provided reference basis and reference value for safety certification of urban rail transit software products.
