摘要: 人机界面是轨道列车控制逻辑与诊断系统的组成部分,是实现列车控制与诊断的重要平台,是司机与列车进行交互的重要接口,它集成了列车状态显示、部分控制命令发送、故障信息及故障措施提示等重要功能。人机界面软件的可靠性直接影响轨道车辆控制系统,甚至轨道列车的可靠运行。本文以人机界面软件为研究对象,研究内容包括以下两个方面:1.        根据轨道列车的实际需求,确定了人机界面部件的组成和功能需求。遵循软件设计的基本原理,将人机界面软件划分为四个功能模块:界面显示模块、人机交互模块、通信模块和中心诊断模块,对每个模块进行了功能设计。考虑操作便捷性、实用性,将人机界面软件划分为多个界面,设计了界面的层次关系。分析人机界面软件每个功能模块的内部结构与工作流程,设计了主要数据结构,对轨道列车人机界面软件进行了编程实现。2.        针对人机界面软件的特点,使用基于复杂度的分配方法对人机界面软件进行了可靠性分配。为了提高人机界面软件的可靠性,首先设计实现了一个人机界面测试软件,检测软件错误并改正,提高模块可靠性,然后基于人机界面软件的模块结构,对人机界面软件进行了可靠性设计,并使用SBRA算法对软件可靠性进行了分析。对用于轨道列车环境的人机界面部件实施了可靠性设计,利用Markov模型分析了部件的可靠性。
英文摘要: The Man-Machine Interface is a part of the control logic and diagnosis system in railway vehicle. It is an important platform for vehicle control and diagnosis, and an important interface for the driver to interact with the vehicle. It contains functions such as vehicle status display, control command send, fault information and fault tips display. The reliability of Man-Machine Interface is critical for the entire control logic and diagnosis system. It can even affect the reliability of the whole railway vehicle. Taking Man-Machine Interface software as the research object, the study includes the following respects.1.        Man-Machine Interface software is divided into several function components According to the actual needs of railway vehicle, to determine the composition and functional requirements of the Man-Machine Interface. Man-Machine Interface software is divided into four function components which include display component, Interaction component, communication component and central diagnostic component following the basic principles of software design. Taking the convenience of operation into consideration, the Man-Machine Interface software is divided into multiple interfaces which are organized to hierarchy structure. The internal structure and work process of each functional component is analyzed which guided the data structure design and programming phase.2.        In view of characteristics of the man machine interface, the reliability allocation is carried on using the complexity and run time-based allocation method. In order to improve the reliability of the man machine interface software, redundancy mechanism is added to some function components After carrying on redundancy design, a scenario-based reliability analysis method is used to calculate the reliability of the man machine interface software, which is compared with the reliability before redundancy design. A software testing software is designed and carried out to test the man machine interface software.
