摘　　要：导引头电子舱是导弹探测、跟踪目标的部件,是导弹系统的关键部分,因此电子舱产品使用前的调试和检测至关重要。介绍了一种基于Nios II的导引头电子舱信号群高速采集系统。该系统采用Cyclone II系列EP2C35芯片,以Nios II软核为核心处理器,完成了对A/D转换后的30路信号群的高速采集处理。与之前采用PCI总线方案相比,此方案简化了硬件电路、减小了设备体积、降低了成本,可以满足不同产品的各种逻辑电平、编码装定、参数预置及功能拓展升级的需求,提高了系统的可靠性和智能化分析处理实验数据的水平。As a key part of the missile system,the electronic cabin can detect and track the target missile,and it is required to be debugged and tested before using. A high speed data acquisition system based on Nios II is designed and realized for the electronic cabin signal group in this paper. Using cyclone series EP2C35 chip and Nios II as core processor,the system can process the signals converted by A / D and complete the high speed data acquisition. Compared with the previous PCI bus program,this system has some advantages,such as simplifying the hardware circuit,reducing equipment size and costs,adapting to a variety of different products' logic level,coding stapling and satisfying needs of presetting parameters and functional expansion upgrade. And it improves the level of reliability and intelligent analysis of experimental data processing system.
