精准农业嵌入式Web服务器的实现

Implementation of Embedded Web Server for Precision Agriculture

对基于ARM9的农田信息在线监测系统进行了研究。系统采用S3C2410X微处理器作为精准农业嵌入式Web服务器的核心,通过工业以太网并辅助GPRS无线网络,实现各细分地块中农田信息与上位机的交互,以及农田现场各执行器动作的远程控制。Web服务器实现了农田信息的远程查询、上位机命令的解释执行以及农田信息的本地化人机交互等功能。实际测试结果表明,该系统具有监测精度高、适应性好、成本低、运行稳定可靠等优点。

The online farmland information monitoring system based on ARM9 is researched. In the system, S3C2410X microprocessor is adopted as the core of the embedded Web server for precision agriculture ; the interaction between farmland information of each subdivided land and the host computer is implemented via industrial Ethemet and GPRS wireless network ; and the remote control of various actuators of farmland sites is also carried out. The functions of remote query of farmland information, interpretive execution of the host computer commands, and localized human machine interaction, etc. , are realized by the Web server. The result of practical test shows that the system possesses advantages of high monitoring accuracy, good adaptability, low cost, stable and reliable operation, etc.
