Implementation of receiving terminal on certain remote sensing image data system and WDM on hardware card based on PCI bus

本文依据某卫星星载数据系统设计要求,对某高速传输的遥感图像数据的实时显示或接收给出了一种地面接收终端的实施方案,着重阐述了对利用PCI总线接口芯片PCI9054实现的硬件接口板卡的WDM驱动程序开发。在windows环境下用Driver Works开发的WDM驱动程序提供了对硬件板卡中断的服务函数、实现了对高速传输数据的DMA方式的接收,配合在用户模式下的应用程序满足了系统对遥感图像数据的实时显示或保存的要求。此种方法对相关领域系统的设计和实现具有普遍意义。

To meeting the requirement of a satellite-based data system, an implementation of grand receiving terminal for the real time display and receiving of remote sensing image data with high-speed transmitting is presented in this paper. The paper focuses on developing WDM drivers of PCI bus for a hardware interface cards based on PCI9054. The WDM driver programmed in the platform of DriverWorks under Windows operation system provide users ISR, realize high-speed data receiving in DMA mode, and have great efficiency on satisfying system real-time performance of transferring and displaying in the remote sensing image data system. The method also has important value to the design and realization in correlative field.
