智能植物生长柜环境测控系统的设计

Design of monitoring and control system of the intelligent plant growth cabinet environment

食品安全问题的频繁出现使得人们对于绿色健康食品的渴望越来越强烈。本文提出了一款基于STM32的智能植物生长柜环境测控系统的设计方案,介绍了系统的工作原理及其硬件组成,同时给出了软件流程图。该系统属于多输入多输出的复杂闭环控制系统,能够实时监测柜体的温湿度、CO2浓度和光强参数;并可根据实测参数实现对温湿度、CO2浓度和光强参数的自动调节,使作物处于最佳的生长环境;可以通过液晶屏实时显示波形曲线的变化,更加直观地了解到作物所处的生长环境。

People are more and more eager to get green food with the problems of food safety occurring frequently, a design of monitoring and control system of the intelligent plant growth cabinet environment based on the STM32 is put forward in this paper. This paper introduces the working pr/neiple, the component of hardware and software and program flow chart of the monitoring and control system, it＇s a complicated closed-loop control system with MIMO, parameters of temperature, humidity, light intensity and C02 density can be collected and adjusted in real time mode, the system can realize automatic control according to the above parameters and provide comfortable environment for the growth of plant. We can get the information of the environment of the intelligent plant growth cabinet on LCD more intuitively.
