装甲车辆虚拟仪表系统设计与实现

Design and Realization of Virtual Instrument in Armored Vehicle

介绍装甲车辆虚拟仪表系统的设计方案,引入突发分频模式采样技术,提出基于事件驱动的CAN总线通信方案,设计了总线状态观测器,并开发了友好的人机交互界面。试验结果表明,开发的虚拟仪表系统数据采集准确、实时性强且稳定性好,为实现装甲车辆数字化和在线故障诊断奠定了技术基础。

In this paper, the design scheme of virtual instrument in the armored vehicle was expatia- ted, paroxysmal FDM sampling mode was introduced, CAN bus communications based on the event drive was brought forward, bus state observation was designed and friendly man-machine interface（MMI） was developed. According to the experimental results, the data collected by the system were exact with sound real-time and high stability, which laid a technical foundation for the armored vehicle digitalization and fault inspection on line.
