为实现茶树生长过程中需水信息的准确检测和茶园精准灌溉的自动控制,设计了一套以Cortex-M3为内核的系统。该系统采用SD存储卡和服务器两种方式存储数据,GPRS传输数据,可实现茶树在不同生长阶段所需水分的自动监测和调控。实验结果表明,该系统运行可靠、操作简单,具有较强的可拓展性,市场应用前景良好。

In order to realize the accurate detection of water needs information in process of tea tree growth and the automatic control of accurate irrigation of tea garden,a system with Cortex-M3 as the core was designed,and the data were stored with two methods of SD memory card and server. The automatic control system used GPRS for data transmission.The system could realize automatical monitoring and regulating for water demand of tea tree at different growth stages. The experimental results show that the system is reliable,simple to operate and has strong expansion ability;it has good market application prospects.
