摘要 [目的]研究蔬菜大棚智能温度控制系统。[方法]设计一种基于计算机自动控制的智能蔬菜大棚温度控制系统,详细阐述了该系统温度采集、温度显示、控制系统、加热器控制电路等系统硬件的设计思想,改进了系统的控制算法,最后利用MATLAB进行系统仿真。[结果]采用模糊控制结合PID控制改进了系统的控制算法。仿真曲线说明该系统有较好的控制和跟踪性能,控温精度较高,还可以和上位机组成二级计算机控制系统,便于实现生产的集中管理。[结论]该研究设计的蔬菜大棚智能温度控制系统人机界面良好,操作简单方便,自动化程度高,造价低廉,具有良好的应用前景和推广价值。 [Objective] The aim of the research was to study the intelligent temperature control system in vegetable greenhouse. [Method] Based on computer automatic control, a kind of intelligent temperature control system in vegetable greenhouse was designed. The design thought of systematic hardwares such as temperature collection system, temperature display, control system, heater control circuit in the heater were expounded in detail, The control algorithm of the system was improved and system simulation was made by using MATLAB finally, [Result]The control algorithm of the system was improved by using fuzzy control combined with PID control, The stimulation curve showed that the system had better controlling and tracking performances, higher accuracy of controlling the temperature. And this system and host epigyny computer could constitute the secondary computer control system, which was favorable for realizing the centralized management of the production. [Conclusion] The intelligent temperature control system in vegetable greenhouse designed in the research had good human-computer interface, simple and convenient operation, high automation degree, low cost and good application foreground and popularization value.
