摘要
以轨道交通列车人机交互显示屏为研究对象,针对当前列车驾驶室人机交互显示屏与车载设备在通信数据量方面所出现的不足,设计了一种基于TRDP列车实时通信的人机交互系统方案。文中以高性能I.MX 8为核心处理器搭建硬件系统,采用基于Linux+QT开发软件系统,研究并实现了列车显示屏TRDP通信口的数据接收、发送功能,还验证了其他人机接口的功能。实验证明,显示屏工作运行稳定,通信网络对外收、发状态运行正常,多接口设计可扩展性强,各性能参数满足列车应用场景要求。
Taking the human-computer interaction display screen of rail transit train as the research object,aiming at the shortage of communication data between the human-computer interaction display screen of train cab and on-board equipment,a human-computer interaction system scheme based on TRDP train real-time communication was designed.In this paper,highperformance I.MX 8 was used as the core processor to build a hardware system,and Linux+QT was used to develop a software system.The data receiving and sending functions of TRDP communication port of train display screen were studied and realized,and the functions of other man-machine interface were also verified.Experiments show that the display screen works stably,the communication network runs normally in the external receiving and sending states,the multi-interface design has strong scalability,and all performance parameters meet the requirements of train application scenarios.
