	The research on test scheme of the digital Electromechanical Actuator based on CAN Bus (EI CONFERENCE) 会议论文 OAI收割 2011 2nd International Conference on Mechanic Automation and Control Engineering, MACE 2011, July 15, 2011 - July 17, 2011, Inner Mongolia, China 作者: Zhang J.; Zhang J.; Zhang Y.; Zhang J. 收藏 \| 浏览/下载：41/0 \| 提交时间：2013/03/25 In order to realize the digital of Electromechanical Actuator(EMA) control system the CAN Bus which has efficient reliable performance and flexible network modes works as data interface.The EMA test scheme is designed based on the CAN Bus.First of all the microcontroller DSP with the CAN Bus works as the core of the EMA control system circuit boards.Then the CAN Bus test network is established with the EMA Ground Test System and Autopilot computer.The function and self-check of the EMA canbe conveniently tested by the network and the result of the test canbe easily displayed in the PC.Finally the CAN Bus test network is established with the EMA the Frequency Characteristics Scanner and etc.The purpose is to test the performance of the EMA.The result of the test can be intuitively showed on the Frequency Characteristics Scanner.In a word the application of the CAN bus provides a new method to test the EMA and reference to engineering the digital EMA which has vital significance. 2011 IEEE.
	Study on image real-time interpretation based on particle filter (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China 作者: Liu S.-J. 收藏 \| 浏览/下载：38/0 \| 提交时间：2013/03/25 In order to satisfy to the real-time requirement of image interpretation system in photoelectric measurement equipments a kind of hardware acceleration system with MIMD distributed multi-processor architecture based on SOPC technology is designed. The particle filter algorithm is proposed to process image interpretation for state estimation problem of nonlinear and non-Gaussian system. This algorithm does not involve conventional linearization transform and has approximated the posterior probability density by a set of discrete particles. Therefore the approximate optimum result is educed. It has a high accuracy and a rapid convergence. Experimental results show that the algorithm be adequate to real time accuracy and robustness meets the requirement of image interpretation and possesses practical significance for engineering applications. 2011 IEEE.
	Design of image interpretation and data-processing system based on SOPC (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Wang Z.-Q.; Liu Z.-R.; Xie M.-J. 收藏 \| 浏览/下载：36/0 \| 提交时间：2013/03/25 In order to follow the development of image interpretation and data-processing system in photoelectric measurement equipments a kind of hardware acceleration system is designed where MIMD distributed multi-processor architecture is used with SOPC technology. System hardware is composed of FPGA SDRAM SRAM FLASH and PCI bridge chip. Four Nios II embedded processors are integrated in a single FPGA chip and communicate with each other by sharing memory. Experimental results indicate that the system meets the requirements of data-processing system in photoelectric measurement equipments and possesses practical significance for engineering applications. 2010 IEEE.
