摘　　要：针对某型导弹随动装置在线检测的需求,设计了基于SoPC的在线检测系统。系统通过装备预留的检测接口进行数据采集,采用基于FPGA+Nios Ⅱ的SoPC架构,应用FIFO缓存和DMA技术,实现对32路信号的快速采集。采用USB接口芯片ISP1362与工控机进行通信,在工控机采用VisualC++6.0开发平台实现系统的检测显示与故障诊断。经实验调试验证,该检测系统能够实现对该型导弹随动装置的在线检测与故障诊断,具有配置灵活、集成度高、开发周期短和便携性好等特点。According to requirements of a missile servo device on-line test, the on-line test system is designed based on SoPC. The system collects data from the reserved ports of the equipment, adopts SoPC design scheme based on FPGA＋Nios II and application of the FIFO buffer and DMA technology, realizes the 32 parallel signals rapid acquisition.Using the USB interface chip ISP1362 to communicate with the IPC,and using Visual C＋＋6.0 development platform to realize the system＇s detection and fault di- agnosis display. As experiment verifies that the designed system can realize on-line test and fault diagnosis, and it has a flexible configuration, high integration, short development cycle and good portability features.
