基于GPRS的茶园土壤温湿度远程监测系统

Design of Soil Temperature and Humidity Remote Monitoring System of Tea Garden Based on GPRS

分析了土壤温湿度对茶树生长的重要影响,设计了一种适用于陕南丘陵山区茶园的土壤温湿度远程监测系统。该统由检测终端中的微控制器通过AT指令控制GPRS模块,基于GPRS网络接入Internet,使检测终端与数据中心之间的TCP连接,将土壤温湿度检测数据远程传输至数据中心,并以数据库方式存储管理。应用结果表明:该系统结构简单、运行成本低廉、网络规模易于扩展,能够有效克服一般监测方式不宜在陕南丘陵山区中使用的缺陷,可为陕南茶叶种植研究提供重要的和可溯源的土壤信息资料。

Analyzed of the important influence of soil temperature and humidity on the growth of tea trees , Designed a kind of soil temperature and humidity remote monitoring system for hilly mountains Tea garden in southern Shaanxi. The system used MCU to control the GPRS module through AT commands , and aceessed to internet by GPRS network, estab- lished TCP connection between the detection terminal and the data center, and remote transmit detection data to the data center, slored and managed data by database. The practieal application showed： simple system structure, low run cost, network size extend easily, it could effectively overcome the shortcoming of the general monitoring methods that could not be used in the hills and mountains, and could provide important and traceable soil information for the research of tea plantations in southern Shanxi.
