Airborne electro-optical stable platform can isolate movement and vibration of the airframe  stabilizes the optic axis of the photoelectic detector  realize the observation and tracking for the object. It has comprehensive application value in army and cicil field. Most of present airborne platforms are analogic control system  digital control system can improve the system general performance  digital control is the development direction of platform systems. In view of the requirements of isolating disturbances and stabilizing optical axis of high-precision photoelectric guidance system  a three-axis stabilized platform system centering on the rate gyro was designed. The disturbance-isolation theory of the stabilized platform was analyzed and the control structure including multiple closed-loops was designed. At last a controller of the servo system based on TMS320F2812 DSP has been designed. Experiment results meet the technical index and precision requirement  and illustrate the practicability and effectiveness of the scheme. 2011 IEEE.

The main methods to measure the target IR features are the following two ways: test and then measurement  or theoretical and simulation calculation. The former is direct measurement so the results are more accurate but the test is costly and complicated  so that it is limited in the application. Theoretical and simulation calculation are widely used in the target IR radiation calibration. Here we give the basic configuration of the calibration platform for measuring the IR radiation of the large area low temperature blackbody source  and discuss the calibration flowchart and key technologies for atmospheric transmission correction. The dynamic data are analyzed in real time to determine the IR radiation features in the data fusion subsystem  and the experimental results show that the calibration method is feasible and practical. 2010 IEEE.

A special Controller Area Network (CAN) bus application layer protocol is designed for the highly reliable communication of microcomputer-based systems in aerocraft control system by analyzing the practical time sequence of data transmission  data priority  data type and data function etc in this paper. Identifier distribution  data storage form  data type  data exchange method and fault handling mechanism of the application layer protocol are specified in detail in the background of a real aerocraft control system. At last a simulation platform based on CAN bus for aerocraft control system is built to validate the design. Experimental results show that this application layer protocol meets the requirements of data transmission reliability  real-time and high efficiency. The bus load rate is low and there is great room for expansion. 2010 IEEE.

This paper presents an intelligent video surveillance system. The system is composed of one or more nodes flexibly according to the application scenarios such as private properties  banks and museums. Each node is an autonomous vision-based device capable to perform intelligent tasks. It is able to digitize and compress the acquired analog video signals in MPEG-4 standard and then transmit the compressed video stream to the control center. At the same time  the node makes use of a statistical approach for real-time detecting moving object and online alarm generation to enable a single human operator to monitor activities over a complex area using a distributed network of active video sensors. The node is implemented on a platform with high performance to ensure that the algorithm is able to run in real-time. Applications demonstrate that the intelligent system has an excellent performance in many scenarios to help people make decisions more accurately and rapidly. 2010 IEEE.

A new DirectShow application in the field of LED Panel display system is shown in this paper. It realizes video processing functions with DirectShow architecture on computer. Source Filter and many Transform Filters  which provided by Microsoft Co.  transform source video into RGB24 format. Then  the video data are scaled up/down to LED panel resolution by Fixformat Filter which inherite CTramsformfilter baseclass. After that  the R/G/B values of video data are adjusted in CCorrect Filter to adapt LED Panel display. Finally  the processed video is shown on LED Wall through DVI or VGA interface. Our experimental results demonstrate that this system makes a good performance. It is greatly simplify the functions of Sending-Board  Receiving Board  and Control-Scanning-Board in display system of the LED Wall. The total cost will be cut down observably  if we can transplant the filters into the embedded platform  to build a special video processing system for LED Panel display. 2009 IEEE.
