摘　　要：使用基于xPC的实时仿真平台进行系统设计、仿真通常需要制作启动软盘来启动目标机,不能很好地兼容较新的计算机设备。利用xPC扩展的嵌入式启动功能,结合Windows虚拟软驱功能,使目标机在宿主机和目标机都不需要软盘支持的条件下启动。在Simulink模型中,使用S函数扩展功能开发CAN通信卡的驱动模块,实现了数字信息的自发自收功能测试。最后使用该仿真平台在StandAlone启动模式下完成了某火炮驱动控制系统实测数据的采集,结果表明该仿真平台实时性能良好,具有很广阔的工程应用价值。Based on the xPC target real-time simulating platform, the startup floppy is generally a necessity for booting the target PC in the design and simulating process of the system, which is not compatible with the newer computer equipment. Combined with the virtual floppy function of the Windows operating system, the extended xPC target embedded option is used to boot the target PC in the condition of none host and target PC. The S-function is used to develop the Simulink blocks for driving the CAN communication card, and the selfsending and self-reception function test of the digital information is realized. This simulating platform is used in the StandAlone mode to complete the real-time signal data acquisition of a gun＇ s driving control system. The result shows that this simulating system has a nice real-time performance and could be widely used in different projects.
