基于3G和STM32的现代农业数据采集系统

介绍一种基于3G和STM3的现代农业数据采集系统,可以实现远距离对无人值守的农业现场进行监测,采集温度、湿度、光照强度等方面数据,通过 nRF24l0无线组网连接温湿度传感器 DHT11和光照传感器BH1750FVI,从而组成一个无线传感器网络,把各节点采集到的数据传到控制中心, RT-Thread嵌入式操作系统为软件平台,采用轻型TCP/IP协议栈LwIP对3G模块MC509进行PPP拨号连接internet,将数据上传到乐为物联网,就可以利用手机APP或计算机对农场的环境进行远程监控和管理。实验表明,系统工作稳定,提供了一种远程无线数据监控的解决方案,对提高农业管理效益具有积极的意义。

Modern Agriculture Data Acquisition System Based on 3G and STM32

A kind of modern agricultural data acquisition system based on STM32 and 3rd Generation (3G) was introduced in this paper. The system could achieve the long-distance agricultural field for unattended monitoring, the collection of temperature, humidity, light intensity and other aspects data. By using the nRF24l01 wireless network was connected to a temperature and humidity sensor DHT11 and BH1750FVI light sensor. The data collected by nodes were transmitted to the control center. The RT-Thread embedded operating system was the software platform, which used light TCP/IP protocol stack LwIP Point to Point Protocol (PPP) dial of 3G module MC509 to connect to the Internet. It could carry out remote monitoring and management of the farm by the use of mobile phone Application (APP) or computer environment when the data was transmitted to the LEWEI Internet. Experiments showed that the system was stable. This paper provided a solution for wireless remote data monitoring. It had positive significance to improve agricultural management benefit.
