高铁联调联试车载集成综合显示平台关键技术研究及应用

联调联试是高速铁路建设和运营准备的重要组成部分和必要环节。当前联调联试20余个专业系统独立运行,缺乏联动。为适应高速铁路高标准建设需要,设计研发的车载集成综合显示平台是各专业协同联动和一体化集成动态显示的新手段,是高铁运营前的重要安全保障。分析车载集成综合显示平台的必要性,针对高速综合检测列车,在空间、功耗、传输、视觉等限制条件下,设计了平台的总体框架、功能结构、综合集成效果、安全传输模式、设备评估指标、主题分区等;并对时空同步、多图联动、可视化、融合分析、集成显示、视觉验证仿真、加固防护等关键技术开展研究;研发成果应用在智能京张高铁联调联试中。

Research and Application of Key Technologies of Comprehensive Onboard Display Platform for HSR Testing and Commissioning

The testing and commissioning is an important part of high speed railway construction and an essential link before commercial operation. The testing and commissioning includes over 20 specialties which function separately. A comprehensive onboard display platform – a new solution incorporating all specialties and boasting integrated and dynamic display function – is developed to meet high standard of HSR construction. The paper analyzes the necessity of the platform, and introduces its design in general architecture, functional structure, comprehensive integration effect, secure transmission mode, equipment evaluation indicators and theme partition under limited space, power consumption, transmission and vision of comprehensive high speed inspection train;studies are also made in terms of space-time synchronization, multi-image linkage, visualization, fusion analysis, integrated display, simulation of visual verification, reinforced protection and other key technologies. The study results have been used for the testing and commissioning of Beijing-Zhangjiakou HSR.
