摘要
北斗信号源是一种重要的北斗检测设备,它通过模拟北斗卫星出站信号来检测北斗用户机的接收性能。CPCI总线是目前军工和科研领域广泛应用的一种工业计算机总线标准,具有速度快、可靠性高等优点。本文介绍了一种将CPCI总线应用于北斗信号源中的设计方法,提出用CPCI总线来实现上位机和北斗信号源之间的通信,给出了利用PCI9052实现CPCI接口模块,直接与北斗信号源中的FPGA连接的硬件电路设计方法,并对用WDM驱动模型和Win2000DDK开发设备驱动程序的方法进行了讨论。
Beidou Signal Generator is an important Beidou-system testing device, which simulate the out-station signal of 13eidou satellite to test the reception capability of Beidou Terminal. The CompactPCI bus is a standard industrial computer bus, which has been widely used in the field of military and scientific research with a feature of high speed and strong reliability. A CompactPCI interface design applied on Beidou Signal Generator was proposed in this paper by which Beidou Signal Generator can communicate with the host control computer. The hardware design of the interface module realized with PCI9052 was presented, which connected with the FPGA used in Beidou Signal Generator. And the WDM device driver developed with Win2000 DDK was analyzed.
