摘要
随着地铁的快速发展,人们在追求舒适性、高效性和经济性等方面的同时,也越来越关注无人驾驶地铁的安全性。在地铁无人驾驶系统中,通常要求牵引传动控制单元满足SIL2级功能安全。本文基于功能安全标准EN50128、EN50129,通过FMEC方法对危害性进行分析,得出控制系统的功能安全需求,并阐释牵引控制功能安全模块的设计与SIL2证书的获得。
With the fast development of subways,the safety of unmanned subway services have attracted more and more attention,along with that on the convenience,eff iciency,low cost,and other aspects of the services.In general,the traction drive control unit of automatic subways is designed to meet Safety Integrity Level(SIL)2 functional safety requirements.Based on the functional safety standards EN 50128 and EN 50129,this paper has performed failure mode effects and criticality(FMEC)analysis,found out the functional safety requirements of the control system,and designed the functional safety module capable of SIL 2 certif ication.
