基于PCI总线的某数字量地面测试设备的设计

摘要

In dynamic tests, how introduced the volume of data into the computer to carry on the analysis restricted to further improve system performance . In this context, by using PCI bus transimit data into the ground test equipment, it realized introducing the data to test equipment in high speed. On the basis of analysising the task and technical index, the whole system solutions are designed. In the hardware implementation, this paper introduced the related technologies in high-speed data transmission process based on PCI bus. In software, combined with the system of reading data process , it introduced structure of the drive and realized the data high-speed and seamless transmission between the PC and the test equipment.%将动态测试中采集到的大容量数据,快速传入计算机进行分析处理,成为进一步提高系统性能的制约因素；在此背景下,利用PCI计算机总线将数据传入地面测试设备的数据接口卡,实现了将外部数据高速传入测试设备.在分析任务及技术指标的基础上,设计了系统总体方案.在硬件实现部分,介绍了基于PCI总线高速数据传输过程中的相关技术；在软件部分,结合系统读取数据的过程,介绍了驱动程序的结构以及实现了上位机和所测设备的数据高速无缝传输.
