摘　　要：烟叶烘烤设备操作复杂、技术含量高、熟练掌握烟叶烘烤技术人员不足等问题,影响了烟叶的烘烤质量。针对上述问题,本文提出了基于小波核极限学习机的烟叶烘烤过程的智能识别方法。实验中对三段式烘烤过程中的叶片变软、主脉变软、勾尖卷边、小打筒、大打筒和干筋6个烘烤阶段分别提取了颜色、纹理和温湿度特征,组建了9维特征向量进入小波核极限学习机,通过增量型算法自适应地选择神经元个数,快速准确地识别了6个阶段,得到了98.33%的识别率。实验结果表明本文提出的基于小波核极限学习机的烟叶烘烤过程的智能识别方法具有一定的可行性,为研发烟叶烘烤智能调控系统奠定了理论基础。In order to solve the problems of large manpower consumption and unstable baking quality in the tobacco curing process,an intelligent recognition method of tobacco curing process based on wavelet kernel limit learning machine is proposed in this paper.In the experiment,the six baking stages including leaf softening,main vein softening,leaf curling,leaf small rolling,leaf large rolling and stem drying during the three-stage baking process were identified.The color,texture,temperature and humidity features were extracted from the six baking stages and a 9-dimensional feature vector was established to enter the wavelet kernel extreme learning machine.The number of neurons was adaptively selected through an incremental algorithm to identify the six stages quickly and accurately.The recognition rate was 98.33%.The experimental results show that the intelligent recognition method of tobacco curing process based on wavelet kernel extreme learning machine is feasible,which lays a theoretical foundation for the development of tobacco curing intelligent control system.
