Abstract

Aiming at the current problems of high power consumption and high cost performance of image acquisition devices for embedded devices,a low-cost and low-power real-time system design program is proposed.In the hardware design,OV2640 CMOS sensor is used as the acquisition front-end,CH565W chip is used as the main control chip for control and processing,and RTL8211FS is used as the Gigabit Ethernet physical layer chip for data transmitting and receiving.For the software design,the image acquisition program with double buffer mode,data transceiver flow and low power management program are introduced.The test results of the system show that the image transmission is clear and smooth,and the power consumption,cost,and real-time performance meet the design requirements.

Abstract

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。
