OPC UA在城市轨道交通信号系统互联互通中的应用研究
|
摘要
数据通信是互联互通的关键,以实现设备互换、联通联运后列车安全可靠运行,基于OPCU A在数据采集、通信方面的高安全可靠性,对其在城轨信号系统互联互通中的应用展开研究。分析了城市轨道交通信号系统架构,从结构功能出发,定义服务器和客户端。在VS2015开发平台上,制作X.509证书,采用SSL协议,使客户端对服务器进行单向认证,对满足OPCUA的服务器和客户端之间信息交互过程进行仿真。结果表明,OPC UA协议能使消息在不同设备间安全交互,与传统多设备多驱动多协议相比,降低了软件设计的复杂度。
Data communication is the key to interconnection.In order to implement the safe and reliable operation of trains after equipment interchange and interconnection,based on the high safety and reliability of OPC UA in data acquisition and communication,this article studied on the application of OPC UA in interconnection and interconnection of urban rail signal system.The paper analyzed the structure of urban rail transit signal system,and defined the server and client from the point of view of structure and function.On the VS2015 development platform,X.509 certificate was made,and the client was authenticated unidirectionally by using the SSL protocol.The process of information exchange between the server and the client satisfying the OPC UA was simulated.The results show that OPC UA protocol can make messages interact safely among different devices,and reduce the complexity of software design compared with traditional multi-device multi-driver multi-protocol.
