摘　　要：针对当前温室大棚控制系统的不足,研究数据融合及模糊控制方法在温室大棚中的应用。利用狄克逊准则(Dixon Criterion)将传感器采集的温度、湿度、光照度3个环境因子数据进行较大误差处理,并采用改进型自适应加权融合算法进行数据融合;使用MATLAB软件的模糊逻辑工具箱设计模糊控制器,以融合后的3个环境因子偏差值作为模糊控制器的输入,以加热器、通风机及补光灯等多个环境控制器信号作为输出,建立多输入、多输出的模糊控制系统。试验结果表明:该方法能使环境因子快速达到环境设置值,稳定状态时数据波动范围较小。该方法能有效改善作物的生长条件,满足温室的控制要求。In response to shortcomings of the current greenhouse control system,the data fusion and fuzzy control method was studied and applied to the greenhouse.The Dixon Criterion was used to deal with large errors in three environmental factors,consisting of temperature,humidity and illumination collected by the sensors,and the improved adaptive weighted fusion algorithm was used for data fusion.The fuzzy controller was designed by using the fuzzy logic toolbox in MATLAB software.Fused deviation values of those environmental factors were used as inputs of the fuzzy controller,while multiple environmental controller signals,such as heaters,ventilators,and fill lamps were used as outputs to establish a multi-input and multi-output fuzzy control system.The test results show that this method can facilitate the environmental factors to quickly reach the required environmental setting values with small fluctuation range of data when the state being stable.This method can effectively improve the growing conditions of crops and meet the control requirements of the greenhouse.
