摘要:
［目的］在各地城市轨道交通机电系统的数字化转型规划和实践中，为适应数字化转型，有必要进行自动售检票系统架构重构和功能重新定义。［方法］根据上海地铁机电系统建设指导意见提出的现场层、车站层和线网层云边端三层架构，并结合上海地铁自动售检票系统接入车站数字化运行平台现阶段实践，在传统自动售检票系统架构基础上，提出了上海地铁自动售检票系统中心层和设备终端层两层架构体系，并重新定义了两层架构的功能，介绍了各层间网络组成。［结果及结论］上海地铁自动售检票系统重构后系统架构的两层间采用直接网络链接通信方式，以适应自动售检票系统业务特点，终端设备层接入车站数字化运行系统也满足了车站日常机电系统管理融合性要求，还明确了车站数字化运行平台中车站服务的功能。重构后的架构适应了数字化转型带来的变化，实现了系统业务与数字化转型下运营管理的结合，简化了管理层级，减少了建设投资。
Abstracts:
［Objective］ In the planning and practice of digital transformation of urban rail transit electromechanical system in various cities, it is necessary to carry out architecture reconstruction and functional redefinition for automatic fare collection system (hereinafter abbreviated as AFC) to adapt to digital transformation. ［Method］ Based on the guidance on the construction of the Shanghai Metro electromechanical system, a cloud edge three-layer architecture for the on-site layer, station layer, and network layer is proposed. Combined with the current practice of Shanghai Metro AFC connected to the station digital operation platform, a two-layer architecture system of Shanghai Metro AFC center layer and equipment terminal layer is proposed on the basis of conventional automatic ticketing system architecture. The functions of the two-layer architecture are redefined, and the network composition between each layer is introduced. ［Result & Conclusion］ After the reconstruction of Shanghai Metro AFC, a direct network connection is adopted between the two layers of the system architecture, to adapt to the business characteristics of the AFC system. The terminal equipment layer is connected to the station digital operation system to meet the integration requirements of the station daily electromechanical system management, and the service functions in the station digital operation platform are also clarified. The restructured system architecture adapts to the changes brought by digital transformation, combines system business with operational management under digital transformation, resulting in simplified management hierarchy and reduced construction investment.
