摘要
地铁线网指挥中心平台以综合监视系统为核心,以数据应用系统、运营执行系统为协同管理。由于关联的设备系统多、业务复杂,海量数据交互的实时性、并发性、准确性要求高,线网指挥中心平台的数据通信问题一直是一个难题。为解决该问题,基于Protocol Buffer通信协议,设计和实现了基于gRPC分布式数据通信的地铁线网指挥中心平台系统架构。远程过程调用gRPC机制是分布式系统和计算机网络中通信的新型机制,在网络化运营模式下通过采集大量的设备数据、业务系统数据,可实现平台数据的规范化处理和业务系统间的高内聚、松耦合通信,提高城市轨道交通运营安全保障能力。
The proposed metro network control center is based on an integrated monitoring system at its core,and uses a data application system and operation execution system for collaborative management.Owing to a large number of associated equipment systems,complex businesses,and high requirements regarding real-time,concurrency,and accurate massive data interaction,the data communication of metro network control centers has always been a problem.To address this,based on the protocol buffer communication framework,a metro network control center architecture based on gRPC distributed data communication is designed and implemented.The remote procedure,called the gRPC mechanism,is a novel communication mechanism in distributed systems and computer networks that collects a large amount of equipment data,business system data,and standardized processing of platform data.Accordingly,it provides high cohesion and loose coupling communication between business systems and improves the operational safety guarantee characteristics of urban rail transit.
