城市轨道交通信号系统的实时数据接口研究

Real-time Data Interface of Urban Rail Transit Signal System

介绍了城市轨道交通不同信号系统的共有数据特性及传输方式。为方便管理、整合数据及集中监测,提出研发一个模块化的数据接口软件以采集各系统实时数据的方案。该方案利用多线程并发技术的接口软件,有效获取多个系统的数据并进行统一存储,从而形成线网级集中监测和管理。可为后续城市轨道交通系统实时数据接口相关规范的制定提供参考。

The current situation of urban rail transit, the common data characteristics and transmission modes shared by different signal systems are introduced. In order to facilitate the management, integrate data and centralized monitoring, the development of a modularized data interface software is proposed to collect the real-time data of each system. By using the interface software of multi-threading concurrent technology, this scheme can effectively acquire data from multiple systems for unified storage so as to form the centralized monitoring and management at network level. The research could provide a reference for the formulation of relevant specifications of the real-time data interface of the subsequent urban rail transit systems.
