Pci Data Acquisition System Drive With Total Control Of Software Development,

With the rapid development of aviation science and technology , on a large extent , the capability of aviation engine has been improved . To meet the requirement of measuring a kind of aviation engine, we successfully developed a suit of multicenter integrated parameters testing system for the aviation engine. These parameters include the rotational speed swing , the fuel flux pulse and pulse pressure. This system has achieved the nod approval of experts and consumer by its many merits , such as real-time data acquisition , high-speed data transferring , multicenter parallel working , operation simply and good expansibility . We can safely say , the precision of aviation engine parameters testing will be improved and the testing period will be shortened by its coming out.In this thesis , according to the rotational speed and flux data acquisition model , we mainly introduce the design of PCI interface , design and program WDM driver on Windows 2000 and the total control application software of high layer used by graph and source code . This thesis emphasize on design PCI interface based on PCI 9052 chip , the constitution way of WDM driver , the I/O transfer operation of driver , the source code of driver's routine , the parallel operation multi-module through multithreading , the design of virtual instrument by LabWindows/CVI , and expatiate on network transfer by MFC socket function .
