摘　　要：LoRa无线通信技术因其长距离、大容量、低功耗等特点在众多低功耗广域网络（LPWAN）技术中脱颖而出。针对农业大棚作物种植中对温湿度信息采集的需要,提出了一种基于LoRa的低成本无线温湿度监测解决方案。该方案以LoRa为无线通信收发设备、LoRa节点采用低功耗MSP430为控制中心,自定义时分通信协议,采集温湿度数据并上报给LoRa网关。LoRa网关采用低成本的STM32控制芯片,同时支持蓝牙和WiFi通信。网关通过蓝牙把收集的各节点数据转发至安卓智能手机。安卓手机实现温湿度数据实时存储、展示及提醒的功能。测试结果表明,该方案具有通信距离远、部署简单、成本低的特点,具有广阔的应用前景。LoRa wireless communication technique stands out in many LPWAN technologies due to several superior characteristics such as long distance,large capacity and low power consumption.For the needs of environmental temperature and humidity information collection for agricultural greenhouse crop cultivation,this paper proposes a lowcost wireless temperature and humidity monitoring solution based on LoRa, which applies LoRa as wireless communication transceiver equipment.The LoRa Node uses low-power-consumption MSP430 as the control center and customizes time division multiplexing communication protocol,achieving the collection of temperature and humidity data,and reporting the data to LoRa Gateway.The LoRa Gateway uses low-cost STM32 control chip,with the function to support Bluetooth and WiFi communications.The gateway transmits the collected data of each node to the Android smart phone through Bluetooth,and the smart phone fulfill the functions such as storage and display the data in real-time.The test results show that the design has features of far communication distance,simple deployment and low-cost,leading to a broad vision of application.
