Abstract

Abstract: In order to realize the adaptive adjustment of greenhouse environmental parameters，based on the greenhouse light intensity and carbon dioxide optimization model，an automatic control system for greenhouse environment was designed. Real time acquisition of temperature，light intensity，CO₂ and other parameters in greenhouse was done by PLC，remote communication was realized through OPC（OLE for process control）communication protocol，combined with data read in real time，according to the optimization model，the optimal CO₂ concentration and light intensity of crop growth in different temperature environment were analyzed and predicted，gas fertilizer generator and fill light lamp were controlled. At the same time，for the convenience of operators monitoring greenhouse real‑time environmental change and making corresponding decision control，a human‑computer interaction GUI interface based on MATLAB was designed.The preliminary test results showed that the control system could be used for crop growth adaptive light and air replenishment.The increment of photosynthetic rate during the regulation period was 1 176. 918 μmol/（m²·s）.Data transmission was steady and real‑time feedback was good.The control system can automatically regulate the greenhouse environment，beneficial to the intelligent development of facility greenhouse.

摘要： 为实现温室环境参数自适应调节，基于温室内光强和二氧化碳寻优模型，设计了温室环境自动调控系统。采用PLC实时采集温室中温度、光强及CO2等参数，通过OPC（OLE for process control）通信协议实现远程通信，结合实时读取的数据，依据寻优模型，分析预测不同温度环境中作物生长的最佳CO₂浓度和光照强度，控制气肥发生器及补光灯工作。同时，为方便操作者监控温室实时环境变化并进行相应的决策调控，设计了基于MATLAB的人机交互GUI界面。初步测试结果表明，该控制系统可完成作物生长自适应补光补气，调控时间段内的光合速率增量为1 176.918 μmol/（m²·s），数据传输稳定，实时反馈效果好。控制系统可自动调控温室环境，有利于设施温室智能化发展进程。
