Monitoring Platform

To solve the difficulty of traditional video monitoring system in system upgrade and expansion, an solution of embedded video monitoring system based on DaVinci technology was put forward in this paper. By building the monitoring platform by DM6437 and DSP/BIOS in the solution, TVP5151 was used for receiving video signal in PAL/NTSC formats, and an JPEG Baseline Profile Encoder was integrated for video encoding, and the 10/100M Ethernet transmission function was realized based on NDK. Finally, the system is tested and the result shows that the system can capture and transmit D1 format signal in 25f/s and met the real-time requirement. At the same time, the system is easy to use and expand with a bright application prospect.

In this paper we propose a novel Adjustable Integrating Pointing device Driver (AIPDD) using software technology to redesign mouse driver to integrate the functions of commercial pointing devices to help them to effectively utilize commercial pointing devices to operate computers. In contrast with the latest studies, the software-based AIPDD has the following benefits. (a) It does not require additional hardware cost and circuit preservation. (b) It supports all commercial pointing devices with standard interfaces of a computer, including PS/2, USB and wireless interfaces. (c) It can integrate unlimited devices simultaneously. (d) It is adjustable in real time. In summary, the AIPDD has the benefits of flexibility, low cost, high efficiency and high device compatibility.

Multiple Tasks

In this paper, a new embedded numerical control (ENC) system for carton samplemaker based on Windows CE is presented. The hardware design of ENC system based on ARM9 processor S3C2440A and motion control chip MCX314As is discussed principally. Besides, the device driver of MCX314As is developed by using stream interface driver model under Windows CE operating system. Furthermore, the software structure of the ENC system is introduced, and the way how to utilize multi-thread technology to realize the real-time control of the carton samplemaker is also discussed in detail. The system is proved to be good at dealing with multiple tasks processing, real-time and reliability of motion control.

Exchange Data

Common Image Generation Interface is the interface between two real-time communication subsystems. In order to exchange data between control end and rendering end of the scene simulation system, a packaging component based on common image generation interface is proposed in this paper, which is applied to visual simulation of helicopters and fighter. The simulation results show that this method can meet the real-time requirement of visual control system and is valuable in visual simulation of the weapon equipment operational field.

In order to improve the accuracy and real-time performance of webpage filtering, a sensitive webpage filter based on multiple filtering was designed. Firstly, the URL is gained from IE browser’s address bar by BHO technology; Secondly, match the webpage text with sensitive vocabulary database using SMA algorithm; Finally, use the sensitive image detecting algorithm combing face detection, skin detection, skin text detection and classification to filter sensitive images in the webpage. The Simulation experimental results showed that the sensitive webpage filter can effectively intercept and filter sensitive webpages, meeting the accuracy and the real-time requirement of webpage filtering.
