摘　　要：分析了液体加热过程特性和噪声特征,将基于升温速率变点的沸腾状态检测转化为白噪声干扰下单边均值变点的在线检测问题。采用累积和控制图进行变点检测,基于积分方程法讨论了控制图参数优化方法。结合加热过程参数的在线估计,构成自适应变点检测方法,对不同加热过程,能够根据过程特点实时更新控制图参数,在实际应用中取得了良好的检测效果。Boiling detection with the detector based on the change of temperature rate can be transformed into the on-line detection for one-sided mean change with Gaussian white noise essentially by the analysis of process feature and noise characteristic for liquid heating. Cumulative sum control charts are used to monitor the boiling and the parameter optimisation is discussed based on the method of integral equation. Combining with real-time estimation of heating process parameters, the adaptive change detection approach is built and can update the parameters of control charts on-line so as to achieve optimal performance for different processes.
