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線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總線介面及其控制固件，實現了通用計算機與測試設備之間基於usb總線的通信功能；其次，在所開發的usb總線介面的基礎上，使用微處理器pic16c62和多路繼電器開關，設計開發出實現測試系統中測試通道切換功能的多路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總線介面測試儀器功能，完成面向測試的上層軟體開發；最後，在深入研究印刷電路板測試方法的基礎上，利用已開發的多路通道掃描器和面向測試軟體，結合必要測試儀器組建印刷電路板測試系統，並對測試結果進行了簡要的誤差分析。Allowing unhandled exceptions in threads to proceed naturally, until the operating system terminates the program, exposes such problems during development and testing
如果允許線程中的未處理異常正常繼續，直到操作系統終止程序為止，將會在開發和測試過程中暴露此問題。The paper discusses the application of the virtual instrument technology on the relay protection testing, and use the usb ( universal serial bus ) as the communication interface between the host machine and testing device
本文論述了虛擬儀器技術在繼電保護測試中的應用，並提出了使用通用串列總線usb作為主機和測試設備之間的通信介面。Defeat bipolar depression week follows two earlier public education programmes about anxiety and panic attacks. the latest initiative involves a special hotline 2606 - 3939 that people can call for a preliminary self evaluation to see whether they have tell - tale symptoms. there is also seminar series with the last one scheduled for this sunday with professor sing lee from the hong kong mood disorders centre talking about bipolar depression research, treatment and prevention
