基于LabVIEW与ARM的农业大棚数据监控系统

Data Monitoring System for Agricultural Greenhouse Based on LabVIEW and ARM

为了便于农业大棚管理者对大棚的整体监控,该文设计了实时多点的农业大棚无线数据采集与控制系统。系统采样节点实现温湿度、雨量、光照等数据采集,采用无线模块SX1278实现433 MHz开放频段的无线数据通讯,将数据传输给汇总站点,汇总站点以STM32F103为控制核心,通过以太网将数据传输给系统远端PC机;基于LabVIEW软件设计了上位机数据管理与监测程序,设计系统在实验室环境下可实现数据下发开闭帘、通风、加热控制指令,实现对各个大棚采样点数据的获取与控制。

The wireless data acquisition and control system for agricultural greenhouse is designed to achieve the goal of the overall control of the greenhouse. The data acquisition point collects the environment data of temperature and humidity,rainfall,light. The aggregation point use SX1278 to receive the data from the data acquisition point. The aggregation point use STM32F103 as the control core and send the environment data to the computer,the data man- agement and monitoring program of upper computer is designed based on LabVIEW software. And the user can send control command to the lower computer to control the curtain,ventilation and heating.
