In traditional metro weak current systems, subsystems built by different manufacturers are physically separated, and devices are redundant while data are isolated. This causes low resource use, high maintenance cost, long customization cycles, and high interface complexity. In this paper, based on an analysis of the problems in traditional metro weak current systems, a novel cloud and microservice-based urban rail transit integrated supervisory control system (ISCS) named ISCS Plus is proposed. The integration mode of each subsystem is determined by analyzing safety requirements, real-time performance, and business characteristics. An infrastructure platform is designed to share resources and isolate applications based on cloud computing technology, while traditional subsystems are decomposed as microservices and merged into different applications. Finally, the entire architecture of ISCS Plus is established and its features are discussed. ISCS Plus plays a key role in the systematic, intelligent, and automatic solution for metro weak current systems and supports the development of the world's leading metro weak current systems.

在传统的地铁弱电流系统中，由不同制造商构建的子系统在物理上是分开的，设备是冗余的，而数据却是隔离的。这导致资源使用率低，维护成本高，定制周期长以及接口复杂性高。本文在分析传统地铁弱电系统存在的问题的基础上，提出了一种新型的基于云和微服务的城市轨道交通综合监控系统（ISCS Plus）。通过分析安全需求，实时性能和业务特征来确定每个子系统的集成模式。基础架构平台旨在基于云计算技术共享资源并隔离应用程序，而传统的子系统则分解为微服务并合并到不同的应用程序中。最后，建立了ISCS Plus的整个体系结构并讨论了其功能。ISCS Plus在地铁弱电流系统的系统化，智能化和自动化解决方案中发挥着关键作用，并支持世界领先的地铁弱电流系统的开发。
