摘　　要：在对隔离型换热节能系统进行实时优化的过程中,数据的粗大误差检测是一个重要的研究内容。为了解决系统输出变量的粗大误差检测问题,对粗大误差的产生、检测的意义和几种检测准则的特点进行了介绍。针对系统实时在线运行特点,提出采用狄克逊准则对系统输出变量的粗大误差进行检测,同时利用实际现场采集的数据进行了实验研究。实验结果表明,文中所采用方法是可行的,并且适合在线应用。In the process of real-time optimization of isolated heat exchange energy-saving system,the gross error detection is an important research part.In order to solve the problem of gross error detection in the system output variables,the generation of gross error and the significance of detection,moreover the characteristics of several detection criterions are introduced.Based on the features of real-time and on-line running,dixon criterion is used to detect the gross error in the system output variables.Using practical data in field,experiment research is carried out.The experiment result shows that the method is feasible and it is fit for being used on-line.
