基于单片机的智慧农业大棚系统设计

Design of intelligent agricultural greenhouse system based on SCM

针对农业大棚中农作物生长依赖温度、土壤湿度等环境信息且生产管理耗费大量人力和管理效率低下等问题,设计了一款基于单片机的智慧农业大棚系统。该系统具有上位机和下位机两部分,上位机以Qt为平台,设计了界面,实现了数据实时监控、参数设定、控制方式选择等功能。下位机以单片机为核心,由各种传感器和外围控制设备等组成,设计了单片机与各个模块之间的接口电路,实现了数据的实时采集和外围设备的控制。系统设计了两种控制方式:手动控制和自动控制。手动控制即传统控制方式;自动控制是将采集的环境信息与设定的阈值进行比较,若不在设定的阈值范围内,则自动开启外围设备调节相应环境,如此便保证了农作物的生长环境,促进农作物的产量。研究结果表明,该系统运行稳定,达到了设计要求,实现了农业大棚的智慧化管理。

Aiming at the problems that crop growth in agricultural greenhouses depends on environmental information such as temperature and soil moisture,and production management consumes a lot of manpower and management efficiency is low,a intelligent agricultural greenhouses system based on SCM is designed.The system has two parts,the upper computer and the lower computer.The upper computer uses Qt as the platform,designs the interface,and realizes the real-time data monitoring,parameter setting,control mode selection and other functions.The lower computer is composed of a variety of sensors and peripheral control devices with a single chip microcomputer as the core.The interface circuit between the single chip microcomputer and each module is designed to achieve real-time data acquisition and control of peripheral devices.Two control modes are designed in the system:manual control and automatic control.Manual control is the traditional control mode;Automatic control is to compare the collected environmental information with the set threshold value.If it is not within the set threshold value range,the peripheral equipment will be automatically turned on to adjust the corresponding environment,so as to ensure the growth environment of crops and promote the yield of crops.The results show that the system runs stably,meets the design requirements,and realizes the intelligent management of agricultural greenhouses.
