Aiming at the requirement that the continuous image transmission and image procession system need the detailed sequence of the IR cameras  the sequence measurement system of the IR camera is designed  and the detailed sequence measurement way of the applied IR camera is carried out. The FPGA programming combined with the SignalTap online observation way has been applied in the sequence measurement system  and the precise sequence of the IR camera's output signal has been achieved  the detailed document of the IR camera has been supplied to the continuous image transmission system  image processing system and etc. The sequence measurement system of the IR camera includes CameraLink input interface part  LVDS input interface part  FPGA part  CameraLink output interface part and etc  thereinto the FPGA part is the key composed part in the sequence measurement system. Both the video signal of the CmaeraLink style and the video signal of LVDS style can be accepted by the sequence measurement system  and because the image processing card and image memory card always use the CameraLink interface as its input interface style  the output signal style of the sequence measurement system has been designed into CameraLink interface. The sequence measurement system does the IR camera's sequence measurement work and meanwhile does the interface transmission work to some cameras. Inside the FPGA of the sequence measurement system  the sequence measurement program  the pixel clock modification  the SignalTap file configuration and the SignalTap online observation has been integrated to realize the precise measurement to the IR camera. Te sequence measurement program written by the verilog language combining the SignalTap tool on line observation can count the line numbers in one frame  pixel numbers in one line and meanwhile account the line offset and row offset of the image. Aiming at the complex sequence of the IR camera's output signal  the sequence measurement system of the IR camera accurately measures the sequence of the project applied camera  supplies the detailed sequence document to the continuous system such as image processing system and image transmission system and gives out the concrete parameters of the fval  lval  pixclk  line offset and row offset. The experiment shows that the sequence measurement system of the IR camera can get the precise sequence measurement result and works stably  laying foundation for the continuous system. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).   Evaluation system of photovoltaic disturbance effect based on simulations (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Electric Information and Control Engineering, ICEICE 2011, April 15, 2011 - April 17, 2011, Wuhan, China 作者:  Li Y.;  Lu M.;  Guo L.-H.;  Li Y.;  Li Y. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 The evaluation system is investigated for the disturbing effect of optical countermeasure device to photoelectrical guided weapon in this paper. The general optical countermeasure simulation model is established by using photoelectrical countermeasure simulation test to conduct the estimation of countermeasure effect. The target-missing quantity of guided weapon and guided precision is designated as evaluating index. Whether the disturbing is valid or not is based on Whether the target-missing quantity is more than 3 times of normal guided precision without disturbance or not. 2011 IEEE.   Design and implementation of Electro-optical Countermeasure Hardware-in-the-loop simulation system based on HLA (EI CONFERENCE) 会议论文  OAI收割 2010 3rd International Conference on Advanced Computer Theory and Engineering, ICACTE 2010, August 20, 2010 - August 22, 2010, Chengdu, China 作者:  Guo J.;  Cui S.;  Guo J.;  Li Y.;  Li Y. 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/25 In this paper  the Electro-optical Countermeasure Hardware-in-the-loop simulation system is introduced  which highlight to problem: real-time control and acquisition of communications data. We discuss the real-time mechanism by the combination of HLA time management mechanism for real-time data communication and out clock  and the double buffer of the acquisition method which ensures high frequency real-time data communications and high data reliability  integrity. The tested data is shown that the Electro-optical Countermeasure Hardware-in-the-Ioop simulation system work properly. 2010 IEEE.
