基于嵌入式系统的虚拟仪器设计

以工控计算机和PC为平台的虚拟仪器系统长期以来充当着智能测试系统的平台。随着后PC时代的来临，业界对仪器的个性化和小型化要求越来越高。嵌入式系统的发展和普及应用使得基于单板计算机和功能板卡的嵌入式仪器成为构建虚拟仪器系统的新思路。本文介绍了应用基于PC-104的嵌入式主板和功能板卡构建虚拟仪器系统的关键技术。

Abstract: Virtual instrument systems based on industrial computer or PC take the role as main platform of smart testing systems for long time. As the era of post-pc comes on, requirement for more customized and more tiny instrument becomes more and more eager. Maturation and wide use of embedded systems make it a new way to construct a embedded instrument that based on single board computer (SBC) and data acquiring board.
In this paper, critical techniques have been proposed to construct embedded instruments that based on pc-104 bus based single board computers (SBC) and function boards.
