高时频潮位数据日高高潮自动识别

Automatic Identification of Daily Higher High Water Level in High Time-Frequency Tidal Water Level Process

以中山市境内感潮河段几个主要的自动测报站高时频潮位过程数据为识别对象,针对其"抖动"、"平峰"现象突出,不同径潮组合过程线"反峰"、"单峰"、"无峰"等形态各异等特点,设计了其日高高潮特征的基本识别办法和辅助识别方法,编制了相应的识别程序,实现了其日高高潮特征值计算机自动识别。该方法简单、高效,可资自动测报站高时频数据特征值电算整编借鉴。

The data in the high time-frequency tidal water level process from the major automatic monitoring stations in the tidal river reach in Zhongshan City was taken as the identification object. According to the characteristics of dithering and average level, and the various configuration of ＂peak reverse＂, ＂single peak＂and ＂no peak＂, the basic identification method and supplemented method was designed for the daily higher high water level. And the relevant identification program was composed to realize the automatic identification of the eigenvalue of the daily higher high water level. This method has proved simple and highly efficient and can be an alternative for the computerization of the eigenvalue of the daily higher high water level in the automatic Hydrometric Station.
