基于ARM田间无线图像嵌入式系统的研究

The Research of Field Embedded Wireless Image Monitor System Based on ARM

针对目前大面积田间管理存在的不足,应用图像处理技术与无线通信技术,设计了基于ARM田间无线图像嵌入式系统。该系统包括图像采集终端和图像监控计算机两部分。图像采集终端根据图像监控计算机的指令采集图像数据,对图像数据进行处理后,将数据通过GPRS网络传送至图像监控计算机;图像监控计算机实时接收、解压缩和显示图像数据,实现用户对现场的实时图像监控。研究设计表明,该系统具有结构简单、功耗低、可扩展性强和移动灵活等特点,特别适合大面积田间管理,具有较强的实时性和可靠性。

According to amount of shortages of the field management nowadays,applying on the image processing technology and the wireless communication technology,a Field Embedded Wireless image monitor system is designed based on ARM.The system includes two parts: image collection terminal and image monitoring computer.The image acquisition terminal collecting the image datum based on the instructions sent by the image monitoring computer,after processing the image datum,the datum are sent to the image monitoring computer by GPRS network;the image monitoring computer receives,decompressions and shows the image datum,so users of the site can achieve real-time image monitoring.Study and design shown that this system is simple,low power consumption,strong scalability,mobile flexible,especially suitable for large-scale field management and it has a strong practicability and reliability.
