摘　　要：随着物联网的发展,海量传感数据的涌入,关系型数据库日益出现功能、性能和稳定性上的瓶颈问题,业界领先的IT公司纷纷开始抛弃单关系型数据库的技术架构,交通运输行业信息系统对处理与存储数据量激增的现有系统进行软硬件架构升级改造与迁移也已是当务之急。本文以北京市实时浮动车系统的升级改造工程为例,阐述了城市交通核心业务系统的传统架构面临的实时计算与存储管理困境、新架构的解决方案,以及升级改造后的提升效果。With the development of the Internet of Things, the influx of mass sensed data, and the bottleneck of relational databasesin functions, performance and stability , the industry, s leading IT companies have started to abandon the technical architecture of single relational databases, md the upgrade, Ixansfomation and migration of tlie software and hardware architectore of existing systems with a soaring size data for processing and storage in the information systems of the transportation industry have also become a priority. Taking the upgrade and transformation project for the real-time probe vehicle system of Beijing for instance, this paper describes the real-time computing and storage management dilemma in the traditional architecture of the urban transportation core business system, n e w architecture solutions, and the effect of enhancement after upgrade and transformation.
