摘要
为了快速获取土壤墒情,满足农田土壤信息监测的需要,设计了一种以太阳能供电的低功耗远程墒情监测系统。系统终端以C8051F040单片机和SIM900A模块为基础进行设计,采集4层深度土壤温度、4层深度土壤湿度以及多种气象信息,利用GPRS网络和短信方式进行墒情数据的自动监测和无线传输。该系统结构简单、使用方便、功耗低,经计算在无光照条件下能够工作14d,实现了农田墒情的低功耗远程实时监测,为农业生产和气象预测提供一定的数据基础。
In order to rapidly collect soil information, a kind of low power consumption monitoring system for soil moisture is de- signed in this paper. Based on C8051F040 and SIMg00A, this system can collect the soil information such as the soil temperature and soil humidity in four depths and multi-kinds of weather information. Then these collected information are transmitted wirelessly through GPRS and short-message Moreover, the system has simple structure, is easy to use, has low power consumption and can monitor the farmland moisture wirelessly. What is more, it provides theoretical basis for the agricultural production and weather forecasL
