基于LORA通信的山地果园灌溉系统

Mountain Orchard Irrigation System Based on LORA Communication

为解决目前山地果园果树灌溉系统存在作用范围小、中继节点布置多和系统部署成本高等问题,本文设计了基于LORA通信的山地果园灌溉系统。该系统通过信息采集终端节点实时采集果园的土壤含水率,通过LORA无线通信网络将土壤信息发送至山地通信控制节点内的路由与控制模块;路由与控制模块对数据进行打包处理,将数据包通过无线分组网(GPRS)将处理后的数据包传输到云服务器;最终,通过不同客户端对云服务器内信息进行展示,实现人机交互。经测试,系统采用直连的方式在面积为20 hm2的山地果园中,通信覆盖面积可达92%以上,较Zig Bee通信方式,可节省中继节点;其长距离通信特点,为系统部署地点提供了更灵活的选择。

There exist some problems in mountain orchard irrigation systems,such as small action scope,large number of relay nodes,high deployment costs,and so on.This paper designs a mountain orchard irrigation system based on LORA communication.The proposed system uses the information collection terminal node to collect the soil moisture content of the orchard in real time,the LORA wireless communication network is used to send the soil information to the routing and control module in the mountain communication control node, and the wireless packet network (GPRS)is used to transmit the processed data packets to the cloud server.Finally,the information in the cloud server is displayed by different clients to realize human-computer interaction.The results demonstrate that the system can cover more than 92%of the communication area of a mountain orchard with an area of 20hectares in direct connection mode.Compared with the ZigBee communication method,the system saves a large number of relay nodes.Because of its long-distance communication characteristics,the communication node can be arranged with more possibilities.
