【摘要】：不同作物的生长发育对土壤湿度有不同的需求,为了给温室大棚农作物提供一个最适宜的生长环境,结合温室大棚现有滴灌系统的特点,设计了一套以ARM11为控制核心、土壤湿度传感器为采集模块、WIFI模块为通信模块的土壤湿度自动控制系统。此系统通过控制与滴灌系统连接的电磁阀保证土壤湿度在适宜的范围内,实现了温室大棚内土壤湿度的远程监测与自动控制;温室大棚管理人员不仅能使用HTTP协议随时、随地访问嵌入式Boa WEB Server来获取实时的土壤湿度数据,还可以通过SQLite嵌入式数据库查询存储的土壤湿度的历史数据。系统测试结果表明,该系统能实现农作物土壤湿度的远程监测与智能调控,运行可靠,测量的土壤湿度绝对误差为±3%,有一定的实用性。
[Abstract]:The growth and development of different crops have different demands on soil moisture. In order to provide a most suitable growth environment for greenhouse crops, combining with the characteristics of the existing drip irrigation system in greenhouse, a set of ARM11 is designed as the control core. The soil moisture sensor is the collection module and the WiFi module is the communication module of the soil moisture automatic control system. This system ensures that the soil moisture is in the suitable range by controlling the solenoid valve connected with the drip irrigation system. Remote monitoring and automatic control of soil moisture in greenhouse are realized. Greenhouse managers can not only use HTTP protocol to access embedded Boa WEB Server at any time to obtain real-time soil moisture data. The system test results show that the system can realize remote monitoring and intelligent control of crop soil moisture, and run reliably. The absolute error of soil moisture is 卤3, which is practical.
