基于ARM的大田视频采集模块设计

Field Video Acquisition Module Design Based on ARM

开发了一种农业视频监控系统,采用主控芯片为S3C2440的FL2440开发板和芯片是Z301的USB摄像头来共同构成模块的硬件操作平台。该模块是对嵌入式Linux内核的剪裁、制作和烧写。同时,对USB摄像头驱动程序、视频采集程序、LED实时显示程序和网络传输程序的设计过程进行了详细的描述,且在农田中进行了模块的现场调试。该大田视频采集模块的成本低廉、性能稳定、功耗低,它采集到的视频图像不仅能显示在LED上,还能通过网络传输程序传输到PC机进行显示,且所显示的视频图像非常地清晰和连贯,符合地理环境上的需求,促进了农业信息化的发展。

Developed a agricultural video monitoring system , which USES the master control chip for FL 2440 S3 C2440 development board and chip is Z 301 USB camera to constitute the hardware platform of the module .This module is to the embedded Linux kernel cutting , making and burning;And the USB camera driver , video collection procedures , LED real-time display program and network transmission of the description of the design process in detail , and has carried on the module in the farmland of the scene debugging .The field of video acquisition module cost is low , good stable performance , low power consumption , it collected video image can not only display on the LED , but also through the network transmission program transmitted to a PC for display , they are shown in the video image is very clear and coherent , very accord with the demand on geographical environment , so as to achieve Agricultural informatization .
