摘要
针对ZigBee、WiFi、GPRS传统无线传感技术在大范围农场等温室环境监测系统的不足,提出了一种基于LoRa技术的低功耗农场环境监测系统;该系统依托物联网思想,分三层结构;其中感知层作为信息采集部分由MSP430单片机、温湿度传感器和光照强度传感器等组成;网络层采用LoRa无线扩频通信技术进行数据传输,可以实现定点、省电、透传和监听4种模式;应用层对网络层传输的数据进行处理和保存,最终实现灯光控制、灌溉控制、降温控制和人机控制。
Aiming at the shortcomings of ZigBee,WiFi and GPRS traditional wireless sensor technology in greenhouse environmental monitoring system on a wide range of farms,presents a low power farm environment monitoring system based on LoRa technology.The system relies on the idea of Internet of things,divided into three layers of structure.The sensing layer as part of the information collected by the MSP430 microcontroller,temperature and humidity sensors and light intensity sensors and other components;Network layer using LoRa wireless spread spectrum communication technology for data transmission,can achieve fixed-point,power,transmission and monitoring four modes;Application layer achieve data processing and preservation,and ultimately to achieve lighting control,irrigation control,cooling control and man-machine control.
