Design And Implementation Of Video Monitor System Based On UClinux

With the embedded Linux technology change and mature, it is increasingly applied in the field of monitoring. As all open source code opening, which became popular for Linux provides a powerful control system, extensive technical support.For such practical needs of this design for a uClinux-based Video Surveillance System.From the analysis, and monitoring of the system functions and performance analysis system needsmonitoring system and use it as the basis for determining the design direction. Based on the analysis of the demand for and use of hardware-based ARM S3C4510B development board CF memory card, CS8900 card, camera top hardware. Software design aimed at developing a uClinux-based hardware used by the driver;Video Capture application software design a monitoring module, video compression module, network transmission control module, video broadcast moduleuser interaction module;In this paper we use and produce Microwindows nano-X as Video Surveillance System GUI interface. Interactive control system to achieve the task.Specific implementation, a serial device driver, will be completed some basic characters storage and display;a CF memory card device driver, CF memory card can enable real-time monitoring of data storage and retrieval;a network adapter device driver CS8900, CS8900 Ethernet cards can be sent.receive data packets from the network, and to achieve long-range computer communications.Use the popular MPEG-4 streaming media format for compressed image data compression control.Xvid based on the use of MPEG-4 encoder and decoder for handling streaming media format. It is set to follow the ISO standard MPEG-4 Video Codec (compressor-decompressor)similar Divx and Xvid a Xvid encoder and decoder. so that the monitoring system can monitor access control terminal image.In view of the characteristics of data transmission control system, the use of real-time Transport Protocol agreementRTP packets in the network for the transmission of data packets to the UDP RTP encapsulation,and the achievement of the RTP data packets sent and received. Finally, the entire monitoring system for the test, the test system usability and stability.This paper describes the design and realization based on the video surveillance system set up a complete monitoring system application platform. This paper studies the content of the research and development of automated monitoring a video surveillance system to provide examples of solutions.
