A novel method for spectral characterization of scanner was proposed in this paper, which combined the principal component analysis (PCA) and back propagation (BP) artificial neural network (ANN). The natural color system (NCS) color patches were ado
摘 要: 大区域空调温湿度系统是难于控制的，极易引起控制系统的振荡，系统很难平稳地过渡到温度设定值，导致极大的能源浪费。文章研究了ANN在大区域中央空调温湿度监控系统中的应用， 从工 程实现角度对相关技术问题作了较细致的探讨。关键词：中央空调系统 温湿度控制 人工神经网络Abstract: It is difficult to control the temperature and Humidity system of central air conditioner for big
