【摘要】 针对当前无线传输技术的多样性,本文通过对GPRS无线图像传输优点的分析,研究了以SIM900模块和C8051F040单片机为核心的苗情图像无线传输系统,重点介绍了系统的硬件和软件设计过程,并在不同时间段对系统进行了图片传输速率的测试,经检验该系统传输一张320*240图片的平均时间为50s,能够实现对苗情图像的定时采集和远距离无线网络传输,具有一定的实用价值。更多还原

【Abstract】 For the diversity of the wireless transmission technology,this paper analyzed the advantages of image wireless transmission through GPRS.And then based on the SIM900 module and c8051f040 microcontroller,the seedlings image wireless transmission system was designed.Here,it is highlighting the system’s hardware and software design process.At last,the picture transmission rate was tested in different time periods and the time of transfering one picture,320?240,was about 50s.From the results,it was not difficult to draw the conclusion that the system could realize the function of seedlings image timing acquisition and long-distance wireless transmission and was also valuable.更多还原
