Research On Fly-By-Light Control System Based On PCI Bus

To satisfy the requirements of Fly-by-Light technology development and to follow up foreign Fly-by-Light technology, this thesis was devoted to the research on technology of optical fiber transmitting circuit on PCI bus, which was used to realize Fly-by-Light control system based on PCI bus. A demo system was subsequently made and its availability was validated.Firstly, this thesis discussed the phylogeny of computer bus and selected PCI bus as the transmission bus of Fly-by-Light control system. After analysis of basic structure, bus protocol, and demands of PCI bus, a conclusion was drawn that PCI bus suited for the reqirment of Fly-by-Light control system.Secondly, this thesis discussed feasibility of optical fiber transmitting circuit on PCI bus from aspects of anti-jamming, transmitting speed, reliability and real time capability. Then, the optical fiber transmitting circuit on PCI bus was developed, which included PCI9054 module, FPGA module and light/electricity module. The circuit can transmit serial signals synchronously in two channels.Thirdly, in order to complete transmission, a driver of transmitting circuit should be developed. So this thesis discussed the theory of windows kernel, which is necessary for programming drivers of transmission circuit on PCI bus. Then programs of reading, writting and interruption were developed and debugged in DriverStudio environment. This thesis also brought forward the installation notice of drivers.Lastly, a test program and a demo system were developed, which demonstrated the fly-by-light control system on PCI bus. The test and the demo indicated that the transmission circuit on PCI bus could transmit at the speed of 4Mbps with high reliability, simultaneity and real-time ability. So it matched demands of Fly-by-Light control system absolutely.
