  1. This paper first begin with the connotation of virtual instrument technology, study and discuss the criterion and the working theory of usb deeply. on the principle of usb1. 1criterion, using usb interface chip usbn9604 and low consumption mirochip c8051f231, we designed the available interface of usb bus and its controlling software, turn the communicating function based usb bus between computer and testing device. second based on the developed interface of usb bus, using microchip pic16c62 and a mount of relays, we designed the multiswitching scanner and its controlling software to complete the funtion of accesses swithing in testing system. third calling the api function inside the windows using vb programming language, communicat with the impelling program of selected hid, achieve the function of testing instrument with usb interface, complete the development of upside software faced testing. at last, based on the deep studying of pcb testing method, used the developed multiswithing scanner and software faced testing, combinated with necessary testing instrument, we constructed the pcb testing system and analized the testing result simply

    論文首先從虛擬儀器的技術內涵出發,深入研究和討論了通用串列總usb規范及工作原理,並依據usb1 . 1規范,採用usb介面晶元usbn9604和低功耗微處理器c8051f231設計開發了通用的usb總介面及其控制固件,實現了通用計算機與設備之間基於usb總的通信功能;其次,在所開發的usb總介面的基礎上,使用微處理器pic16c62和多電器開關,設計開發出實現系統通道切換功能的多通道掃描器及其控制固件;再次,採用vb語言編程,調用windows內部api函數,與選定hid類驅動程序進行通信,實現usb總介面儀器功能,完成面向的上層軟體開發;最後,在深入研究印刷電方法的基礎上,利用已開發的多通道掃描器和面向軟體,結合必要儀器組建印刷電系統,並對結果進行了簡要的誤差分析。
