基于智能手机的农田墒情远程监测系统

针对农田信息采集的需要,设计了一套基于智能手机的远程监测系统。在Windows Mobile 6.1嵌入式操作系统平台上开发了基于GSM短信息服务平台的SMS系统,从而有效地利用AT命令实现了对短信息收发的控制。系统采集农田中土壤温度、作物叶片温度、土壤含水量和光照强度信息数据,控制网关基于ARM9和嵌入式Linux操作系统进行设计,用于农田信息的接收、实时显示和存储,通过GPRS方式实现与远程智能手机的通信。该系统可以通过智能手机实时收集农田信息参数或发送农田信息控制命令,并依据采集的信息参数进行控制作业。实验结果证明,该设计可行性良好,系统运行效果满足实际要求。

Remote Monitoring System for Soil Moisture Based on Smart-phone Platform

For meeting the needs of information collection of agriculture,a remote monitoring system was developed based on the smart-phone platform.A SMS module on Windows Mobile OS 6.1 is developed based on GSM protocol system,which implements sending and receiving messages efficiently by AT command.System collects soil temperature、crop leaf temperature、soil moisture and light intensity information,control gateway was designed based on ARM9 and embedded Linux operating system,which received、real-time display and storage the information of field and communicated with the remote smart phone by GPRS.This system can collect information parameters of cropland in real time through smart-phone or send control orders,meanwhile,it can conduct control according to the collected formation parameters.The rational design makes the system cost less and easy to be operate,which is proved by test results.
