摘　　要：随着城轨信号系统信息化的发展,列车自动监控系统(Automatic Train Supervision,ATS)云化、数据融合、全自动驾驶等新兴技术的应用导致各系统间数据类型及数量急剧增加,在实时性、可靠性、业务开发成本等方面为ATS的分布式协作系统架构带来挑战。提出一种基于Redis的ATS缓存系统设计,具备高实时性、高可用性和灵活的数据扩展性,同时结合ATS分布自律的特性,实现了网络冗余、数据同步等功能。With the development of informational urban rail transit technology,applications of emerging technologies such as ATS(automatic train supervision)cloudification,data fusion,and fully automatic operation cause the volume and variety of data increasing rapidly.It has brought challenges to current ATS distributed collaboration system in velocity,reliability and business cost.This paper proposes a design of Redis-based ATS caching system,which shows advantages in real-time performance,availability and data scalability.Combined with the characteristics of ATS distributed system,the proposed system achieved network redundancy,data synchronization and other functions.
