地铁综合监控系统的权限控制策略方案应用研究

Research on the application of authority control strategy in metro integrated supervisory control system

地铁综合监控系统是一个功能强大的、开放的、模块化、可扩展的分布式控制系统,集成和互联了多个子系统。简单的用户和权限管理模式无法适应地铁ISCS系统多站点、多专业、多控制级别、多用户类型的需求。文章详细介绍了DSC9000+综合监控系统平台的系统用户安全管理机制和用户管理与授权方案。

The subway Integrated supervisory control system(ISCS)is a powerful,open,modular and expandable distributed control system that integrates and interconnects multiple subsystems.The simple user and authority management mode cannot meet the needs of ISCS system for multiple sites,multiple disciplines,multiple control levels,and multiple user types.This article introduces the user security management mechanism and user authorization scheme of the DSC-9000+ISCS system.
