轨道交通车辆软件开发过程中的质量保证措施

基于EN 50128标准提出轨道交通车辆软件系统全生命周期质量管控策略。在遵循国际标准认证的质量管理体系框架内,定义适合轨道交通车辆软件产品生命周期模型及各阶段质量保证任务。针对软件生命周期各阶段不同质量任务,全面阐述软件需求、架构设计、软件编码、软件测试及维护运营等各阶段保证软件质量的管理方法和措施。通过制定并运用软件需求检查清单、安全性设计技术、编码规范、验收测试标准、维护变更管理等质量审核手段,来保障软件产品的质量要求。

Quality Assurance Measures for the Software Development of Rail Transit Vehicle

In this paper,based on the life cycle of software quality control strategy in Standard EN 50128 for rail transit vehicle,and following the international standard authentication within the framework of quality management system,a product life cycle model suitable for rail transit vehicle and software quality assurance at different stages is defined. In view of different qualities and software life cycle tasks at all stages,the software requirements,architecture design,software coding, software test and maintenance to ensure the quality of software operation are comprehensively elaborated. By making and using the checklist of software requirements,design of safety technical measures,coding standards,acceptance test standard, maintenance quality audit means such as management changes,the software product quality is ensured according to the application requirements.
