Based On The Pci Bus Data Acquisition System

This paper mainly studied the realization and application of data acquisition system using the PCI bus.With the rapid development of information technology (IT), especial computer technology, industry and agriculture manufacture, medical and scientific research bring forward higher request for data gathering and processing. China relatively drops behind other developed countries in making use of high speed PCI Bus technology. The thesis is put forward in order to settle the question.The thesis includes the design of hard circuit, PCB(Printed Circuit Board), Driver and application soft involving A/D board and D/A board. The detailed functional modules consist of multiplex signals select module,analog digital conversion module,digital analog conversion module,PCI protocol conversion module,driver and magnifying module,control logic,clock circuit and configuration circuit. The importance of the thesis is A/D board. The thesis emphasizes the application of newly PCI Bus specification 2.2 in data acquisition system and the development of driver using the PCI9030 chip which is just studied and produced in PLX Company in 2000. The hard circuit is drawn employing circuit soft Protel99. The driver is developed using developing tool WinDriver5.3 and the application soft is programmed making use of advanced programming soft Visual C++ 6.0. This thesis basically has been completed hard circuit debug,driver develop and installation,has been received good customers' comments. This paper mainly states the meaning and task of data acquisition,newly trends of data acquisition system using today PCI Bus technology,foundation theory of data acquisition, most contents of PCI 2.2 specification,hard circuit design of PCI data acquisition system,design of driver,development of application soft and application of the whole system...
