【摘要】：本设计实现了视频监控和物理量的监控。系统基于ARM9的嵌入式微控制器S3C2410芯片，选用国内消费类摄像头市场占有率最高的中星微摄像头，通过USB接口数码摄像头采集图像并利用摄像头的图像处理器(Embedded Processor)压缩成JPEG，在ARM芯片上处理成MJPEG视频格式。通过嵌入式WEB服务器boa实现WEB远程监控，，配置boa并利用JwebPlayer java applet小应用程序在网页上显示实时视频，通过外接12位串行A/D tlc2543实现物理量的监控。本系统的开发使用优龙公司ST2410开发板，利用免费的可剪裁的嵌入式Linux操作系统，内核版本为Linux-2.6.8.1，对操作系统进行针对S3C2410体系结构的移植，并根据系统需要进行系统模块配置，以及其他相关软件的移植。根文件系统为cramfs文件系统。利用开源项目gspca万能驱动作为USB摄像头的驱动，对gspca进行arm-Linux的移植，利用开源软件作视频的采集和显示。在服务器端，编写A/D的arm-Linux驱动程序和应用程序，应用程序采集数据到临时文件中。在客户端，应用applet动态显示采集物理量。
[Abstract]:The system is based on ARM9 embedded microcontroller S3C2410 chip, the domestic consumer camera market share is the highest in the star micro camera. The image is captured by the digital camera of USB interface and compressed into JPEG by using the image processor of the camera. It is processed into MJPEG video format on ARM chip. WEB remote monitoring is realized by embedded WEB server boa. Configure boa and use the JwebPlayer java applet applet to display live video on a Web page. The physical quantity is monitored by 12 bit serial A / D tlc2543. The development of the system uses the Yulong company ST2410 development board, using the free clipping embedded Linux operating system, the kernel version is Linux-2.6.8.1. The operating system is transplanted to the S3C2410 architecture, and the system module is configured according to the system needs. And other related software porting. Root file system for cramfs file system. Using open source project gspca universal driver as USB camera driver. The arm-Linux is transplanted to gspca, and the open source software is used to collect and display the video. On the server side, the arm-Linux driver and application of A / D are written. Application program to collect data into the temporary file. In the client, the use of applet dynamic display collection of physical quantities.
