基于Linux-FLTK的动车组人机界面软件设计

列车人机通信系统是列车网络监控系统的重要组成部分，其主要功能可显示车辆当前运行状态、报警和故障信息，可实现列车重要控制功能，可保存车辆运行历史数据等。本文设计了一种基于Linux-FLTK（Fast Light Tool Kit）的人机界面，采用性能优越的ARM架构作为硬件平台、采用稳定性强的嵌入式Linux作为软件平台，利用开源图形工具FLULD进行程序界面开发。经过验证，该程序具有编程结构简化、开发周期短，可移植性强，目标程序小等优点，在轨道车辆领域得到广泛应用。

EMU’s HMI software based on Linux-FLTK

Human-machine interface system is an important part of train control and monitoring system. The main functions of HMI are displaying the train’s current operating states and failure information, alarming. It can also implement train control function and store the historical dates of train’s operations, and so on. This article designed a human-machine interface based on Linux-FLTK, using ARM framework as the hardware platform, embedded Linux as the software platform, open-source graphics tool FLULD to develop the program interface. After verification, the program has the advantages of programmed with simple structure, short development cycle, strong portability, small target program. Now it has the wide field of application in rail vehicle industries.
