Zusammenfassung:	A method 300 of detecting at least one frozen period in at least one sensor dataset associated with at least one sensor 222A-222C in a technical system 220A-220C. The method comprises receiving the atleast one sensor dataset in time series, computing run-lengths for the at least one sensor dataset, wherein each of the run-lengths is length of consecutive repetitions of a sensor value in the at least one sensor dataset. The method includes clustering the run-lengths into one of two clusters based on a run frequency, wherein the run frequency is a number of times the run-lengths are repeated inthe at least one sensor dataset. Further, the method includes identifying a cluster from the two clusters with lower run frequency and detecting the at least one frozen period in the at least one sensor dataset based on the identified cluster. 一种检测与技术系统220A-220C中的至少一个传感器222A-222C相关联的至少一个传感器数据集中的至少一个冻结时段的方法300。所述方法包括按时间序列接收所述至少一个传感器数据集，计算所述至少一个传感器数据集的运行长度，其中运行长度中的每个是所述至少一个传感器数据集中的传感器值的连续重复的长度。所述方法包括基于运行频率而将运行长度聚类到两个聚类之一中，其
