摘要
从国内外发展来看,物联网技术正驱动农业向数字化、精细化方向发展。LoRa技术具备广域覆盖、低功耗、低成本和抗干扰能力强等特性。农业环境较复杂,需要传感器定期上传数据,且WiFi、ZigBee、蓝牙技术不能兼顾远距离和低功耗。基于此,以农业大棚为例,提出采用LoRa技术进行通信,将传感器采集的环境数据传输至远程或者本地服务器,实现农田环境管理。
From the perspective of domestic and international development,Internet of Things(IOT)technology is driving agriculture to the direction of digitalization and refinement.LoRa technology has the characteristics of wide area coverage,low power consumption,low cost and strong anti-jamming ability.Agricultural environment is complex,which requires sensors to upload data regularly,and WiFi,ZigBee and Bluetooth technologies can not take into account both long-distance and low power consumption.Based on this,taking agricultural greenhouse as an example,LoRa technology is used to communicate,and the environmental data collected by sensors are transmitted to remote or local servers to realize farmland environmental management.
