Research On Fly-By-Light Flight Control System Based On USB

To satisfy the requirements of Fly-by-Light control system on the communication speed, this thesis discussed the innovative idea of the distributed Fly-by-Light system based on USB, and researched on key technologies of Fly-by-Light technology based on USB, and developed successfully the Fly-by-Light prototype based on USB, which was demonstrated by semi-substantial simulation. This thesis also researched on key hardware technologies of Fly-by-Light system based on PCI, which had two bir-direction optic channels.Firstly, the framework and electric characteristics of USB system were described in this paper. Based on that, remarkable success was obtained in works on multi-channel optical communication system, in which the WDM technology was utilized. This system allows the transferring of three channel signals simultaneously through one fiber, in which each channel works at the speed of 3Mbps.Secondly, to satisfy the point-to-point communications of Fly-by-Light control system, the Fly-by-Light prototype based on USB was designed, in which single-channel also works at the speed of 3Mbps.Thirdly, the optical assistant landing simulation system based on manual control was developed to demonstrate the USB optical interface components this paper designed.Last, Fly-by-Light control system based on PCI was designed in this thesis to satisfy high-speed communication. This system has two bir-directional optic channels to achieve bir-directional transfers and uses FPGA as transmission controller. This paper mainly designed the hardware part and stressed FPGA designs.
