| 摘 要： | 利用统计学变点检测理论对冰层厚度传感器每个测点测量到的电压值进行分析计算,并做出变点判断;利用Matlab进行了仿真试验。结果表明,利用最小一乘法变点判断程序能准确地判断出空气与冰、水与冰的变点,并能够对野值电压进行排除。用这种方法对冰层厚度的变点判断精度高、速度快。 |

| Abstract: | Making use of statistics in the change-point theory for detecting ice thickness,the analysis and calculations were conducted on the voltage values measured at each measuring point of ice thickness sensors so as to determine the change-point.The Matlab simulation results show that the Least-Absolute-Deviation-based change-point determining program can accurately determine the change-point between air and and ice or between water and ice,and rule out outlier voltages.Therefore,accurate and fast determination of ice thickness can be achieved using this method. |
