摘要
针对远离社区、通讯不畅、布线困难、无人值守的场所,图像数据传输一直困扰着应用管理者,本文实现一种基于嵌入式和Linux的无线图像传输系统,以嵌入式技术研发应用为基础,通过Jz4730主控CPU模块、HGTU-600 GPRS无线数据传输模块及OV511图像采集控制系统构建硬件系统,应用软件开发技术实现图像传感器数据采集、图像数据编码和解码及其远程无线传输,并研发客户端应用管理软件系统,实现与云端管理服务器的数据通信。试验结果表明,图像数据在无线网络中传输稳定可靠,系统数据包传输平均丢失率小于0.01%,数据传输平均响应时间小于1.6 s,可有效满足图像数据的传输要求。客户端应用管理软件功能模块工作正常,图像数据显示清晰完整,数据查询响应时间小于2 s。系统具有较好的应用场景,尤其适用于各类农林系统、农业园区、野外台站等生态环境野外观测。
The image data transmission has been perplexing the application managers in the places far away from the community,poor communication,difficult wiring and unattended.In this paper,a wireless image transmission system based on embedded and Linux is implemented.The system is based on the research and application of embedded technology.The hardware system is built through Jz4730 main control CPU module,HGTU-600 GPRS wireless data transmission module and Ov511 image acquisition and control system.Image sensor data acquisition,image data coding and decoding,and remote wireless transmission is achieved through software development technology.A client application management software system is developed to achieve data communication with cloud server.The test results show that the image data transmission in wireless network is stable and reliable,the average loss rate of system data packet transmission is less than 0.01%,and the average response time of data transmission is less than 1.6 seconds,which can effectively meet the transmission requirements of image data.The client application management software function module works normally,the displayed image data is clear and complete,and the data query response time is less than 2 seconds.The system has good application scenarios,especially suitable for all kinds of agricultural and forestry systems,agricultural parks,field stations and other field ecological environment observation.
