【摘要】 本文主要针对导弹测试系统中多通道数据采集的任务,提出了基于FPGA平台的PXI总线接口通用设计方案,并实现了PXI总线接口模块的电路设计和驱动程序的开发。然后根据PXI总线体系的要求,完成了32通道数据采集系统硬件设计和仪器软面板设计。该方案的成功实现对于组建自定义的总线化测试系统具有十分重要的意义,标志着自主化的PXI总线接口关键技术的突破。更多还原

【Abstract】 In this paper, a flexible self-designed PXI bus interface scheme is proposed, and implemented with FPGA platforms and the WINDriver software to meet the requirements of PXI bus test systems in the navigation field. Additionally, a 32-channel A/D data acquisition system and its soft panel based on the PXI bus is accomplished for a missile ground test system. The success of this scheme represents a breakthrough of the researches on self-designed PXI bus interface, and gives a lot of support to the future work as well.更多还原
