The Design Of A Read Out Systerm For Linear CCD

The thesis introduces a Readout Systerm for Linear CCD, in the development background of CCD technology applied to be explored in the twinkling fiber array detector. In this thesis,the software of the disign is completed, which includes the driver and the application. At the same time,the fiber and PCI transmission board is designed. At last,the function for readout and transmission of the systerm is tested and the the test results are given.Firstly,the thesis intruoduces the function,hadware design and software design of the CCD readout systerm. Among them,the task of the PCI optical fiber transmission board and the software design is the key point. This paper introduces the PCI optical fiber transmission board's function, the design of every module and the PCB design for the board. Optical fiber transmission and Roketl/O technology, the PCI bus characteristics, the collocation method and the way of data transmission are also introduced. The board can be used as a common transmission. The software design of the systerm includes driver and PC program design of the data acquisition software.The main task of the software design is to read, to process data, to display and to realize the control of PC. In the systerm, USB and PCI bus are both used for data transmission, so the driver will be introduced is for usb and PCI bus. The development tool for usb driver is WinDriver and the tool for PCI diver is PLX SDK. Both WiDriver and PLX SDK belong to the category of WDM driver. The development platform for software is VC++6.0 and LabVIEW8.0. The DLL file is compiled in VC++6.0 and the pecific data transmission can be completed in the DLL export function. The tool to develop PC interface is LabVIEW. The mian task of LabVIEW is to call DLL file from its call library function node and compete the work to obtain the data and then, process and display, besides, the control program for usb and PCI equipment is completed. Finally, a test is made. The data transfer rate of usb and PCI bus is tested and the test result of linear CCD data acquiring is given.
