摘　　要：为解决烟草红外水分仪核查周期难以确定的问题,提出一种基于维纳(Wiener)退化过程的水分仪核查周期确定方法。在对烟草生产过程中采集到的大量水分仪历史退化数据和在线测量数据进行分析的基础上,采用带自适应漂移项的Wiener过程模型对历史退化数据进行建模,以获取水分仪未来退化状况的信息,从而确定水分仪的核查周期。在新的数据到来之后,引入卡尔曼滤波对自适应漂移参数进行更新,对红外水分仪剩余寿命进行重新估计,以实现红外水分仪核查周期的动态调整。研究结果表明,与传统方法相比,该方法更符合实际情况且能够实现在线预测,在该案例下的烟草红外水分仪的核查周期应当设置在6~7 d之间。In order to solve the problem that the verification cycle of tobacco infrared moisture meter is difficult to determine,a method of determining the verification cycle of moisture meter based on Wiener degradation process is proposed.On the basis of the analysis of a large number of historical degradation data and online measurement data collected during tobacco production,the historical degradation data is modeled using the Wiener process model with adaptive drift terms to obtain information on the future degradation of the moisture meter,thereby determining the verification cycle of the moisture meter.After the arrival of new data,Kalman filters are introduced to update the adaptive drift parameters and re-estimate the remaining life of the infrared moisture meter to achieve dynamic adjustment of the infrared moisture meter verification cycle.The results show that the method is more realistic and can achieve online prediction than the traditional method,and the verification period of the tobacco infrared moisture meter in this case should be set between 6-7 days.
