基于LoRa的温室远程灌溉系统研究

Research on Greenhouse Remote Irrigation System Based on LoRa

针对西北地区农业条件差、水资源匮乏等问题,研究和开发了一种温室远程灌溉系统。该系统结合传感器技术、LoRa通讯技术、云平台应用技术、数据库应用技术以及ASP.NET应用程序开发技术,从上到下搭建一整套远程灌溉系统。该系统通过数据采集节点对温室内环境参数进行及时监测,并将数据上传;电磁阀控制节点接收远程用户指令执行灌溉任务;现场控制器节点则连接子节点和云服务平台,对数据和指令进行解析、中转任务;结合数据库技术和ASP.NET应用程序开发技术,开发B/S结构WEB应用程序,为用户进行远程监控提供平台。

Aiming at the problems of poor agricultural conditions and lack of water resources in Northwest China,the greenhouse remote irrigation system was studied and developed.The system combined with sensor technology,LoRa communication technology,cloud platform application technology,database application technology and ASP.NET application development technology to build a set of remote irrigation system from top to bottom.The system monitored and uploaded the environmental parameters of greenhouse in time through data acquisition nodes;the solenoid valve control node received instructions from remote users to perform irrigation tasks;the field controller node connected sub-nodes and cloud service platform to parse and transfer data and instructions;combined with database technology and ASP.NET application development technology,the author developed WEB applications based on B/S structure,which provided for a platform for remote monitoring of users.
