China Standard EMU Human-machine Interaction Display Program Development And Application

At present,with the implementation and development of China's "One Belt And One Road" strategy,China high-speed railway has entered the stage of high-speed development.After years of efforts,China's independent research and development of China's standard motor vehicle group "Recovery" has successfully passed the assessment,and began to carry passengers on the Beijing-Shanghai line.China standard the emu as a fully customized brand of China's high-speed rail,deeply domestic and foreign,its appearance design with Chinese characteristics and humanized interior facilities and train network system security and stability is a highlight of the "Renaissance".The development of high-speed train group technology promotes the development of train network control technology.Train network control technology is the core technology of the emu technology,cab human-computer interaction system HMI(Human Machine Interfere)is an important part of the train network control technology,the driver display HMI software development platform to build,directly affect the development of train network control system.It is of great significance to build an open and extensible intelligent driver display software development platform,and to build a completely autonomous train network control system and to the development of the vehicle group technologyThe main research contents of this paper include:(1)The development and current situation of train network technology in China,and the technical development of HMI in the driver's cab in the train network system.Introduces a kind of Embedded operating system based on Qt interface,constructed based on Qt/Embedded interface hardware and software of the Embedded system development environment,contains Qt/Embedded installation and setup,the transplantation of Embedded Linux operating system in libraries,the interface design of Qt Designer.(2)Expounded based on the Qt application development process,platform building process is described in detail,illustrates the construction of the application framework and the process of programming,briefly explain how to use Qt Designer to complete the interface design and the associated process and procedure.(3)Verify the full interface and function of the display screen of the driver's room through test bed test and current vehicle test,and ensure that the display program reaches the loading condition.According to the following problems in the process of actual operation solution for problem analysis and confirm the problem,improve the display program,to ensure the safety of the cab display,stable,and efficient use.
