【摘要】 农田数据采集是是获取农田小区生长环境数据空间分布差异性的基础。农田数据采集具有采集周期长、速率低、数据量小、通信距离长、采集点分散、环境差等特点。本文进行了GSM短消息技术应用于土壤墒情监测的可行性研究,开发了以太阳能供电的基于TC35i和ATmega32低功耗微控制器的测量平台,并配合EC-5型土壤水分传感器组建了一套农田墒情监测系统。运行结果表明在农田墒情信息获取系统中采用SMS通信技术具有低成本、易实现的优点,具有很好的应用前景。更多还原

【Abstract】 A study on GSM–SMS technology application to field soil moisture acquisition was presented in this paper.This study is based on a field data collection system that is composed of PC,field monitoring sensors,TC35i modules and ATmeg32 microcontroller.The data transmissions,communication,are accomplished via GSM – SMS technology.After establishing the monitoring system,the authentication and performance tests were conducted in Xiaotangshan.Based on the performance testing results over 1 year,the in-tegrity and performance of transmission is guaranteed.The GSM-SMS technology is well suited for implementation in field data moni-toring and acquisition.GSM–SMS technology application to field data acquisition system is cheap and feasible.更多还原
