以工控計算機和PC為平臺的虛擬儀器系統(tǒng)長期以來充當著智能測試系統(tǒng)的平臺。隨著后PC時代的來臨，業(yè)界對儀器的個性化和小型化要求越來越高。嵌入式系統(tǒng)的發(fā)展和普及應(yīng)用使得基于單板計算機和功能板卡的嵌入式儀器成為構(gòu)建虛擬儀器系統(tǒng)的新思路。本文介紹了應(yīng)用基于PC-104的嵌入式主板和功能板卡構(gòu)建虛擬儀器系統(tǒng)的關(guān)鍵技術(shù)。

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.
