基于LORA通信的茶园雾灌监测系统设计与实现

Design and Implementation of Tea Garden Fog Irrigation Monitoring System Based on LORA Communication

为量化雾灌对茶园茶树的作用效果,提供合理的灌溉建议,设计了一套基于LORA通信的茶园雾灌监测系统。该系统通过环境采集终端节点采集茶园的土壤、大气温湿度信息,利用LORA通信网络将信息汇聚于茶园通信控制节点;通信控制节点一方面将信息进行缓存,进行本地的信息备份,另一方面将数据进行封装处理,利用4G网络将数据发送至云服务器端;最终,面向不同用户提供不同的人机交互方式。通过野外实地持续20 d监测茶园雾灌,测试表明雾灌操作主要影响大气温湿度,可用于创造适宜茶树生长的大气环境,而对土壤温湿度的影响则较小,但在水土保持方面有着较好的表现。

In order to quantify the effect of fog irrigation on tea plantation and provide reasonable irrigation suggestions,a monitoring system for tea plantation fog irrigation based on LORA communication is designed in this paper.The system collects the soil and air temperature and humidity information of tea garden through the terminal node of environmental collection,and collects the information in the communication control node by using LORA communication network.On the one hand,the communication control node temporarily stores the information and backs up the local information,on the other hand,it encapsulates and processes the data,and sends the data to the cloud server by using the 4 G network.Users are provided different ways of human-computer interaction.The system continuously monitors the effect of fog irrigation on tea garden for 20 days.The experiment proves that fog irrigation mainly affects the atmospheric temperature and humidity,and can be used to create an atmospheric environment suitable for tea tree growth,while the effect on soil temperature and humidity is small,but it has a good performance in soil and water conservation.
