Problems solved by technology

At present, most of the monitoring of hydraulic structures such as dams uses the form of "point" sensor monitoring. During the long-term or uninterrupted continuous monitoring process, the monitoring information is large-capacity and diversified. The traditional monitoring information processing method is difficult to meet the speed and capacity requirements

Embodiment 1

[0021] Embodiment 1: A hydraulic structure operating state monitoring system based on time series clustering fusion. When using the hydraulic structure operating state monitoring system based on time series clustering fusion, it is necessary to rationally optimize the arrangement of measuring points for key parts of the measured structure . Such as face rockfill dams, when evaluating the structural performance of face rockfill dams, the commonly used indicators are: internal and external deformation of the dam body, seepage, stress and strain, face disturbance, etc.; and the main items to be monitored for concrete dams are: deformation , stress, seepage volume, uplift pressure and expansion joints, etc.

[0022] Taking the concrete face rockfill dam with a large amount of monitoring as an example, 26 deformation monitoring points are arranged on the surface of the dam body, which are respectively arranged on the face surface, downstream dam slope surface, and downstream slope ...

Abstract

The invention relates to the technical field of structure operation state monitoring in water conservancy and hydropower engineering, and specifically relates to a hydraulic structure operation statemonitoring system based on time sequence clustering fusion. A certain number of sensors are arranged at different monitoring parts of the hydraulic structure. A signal line is connected into the control room. A large amount of monitoring data is acquired through sensor equipment. A clustering method is adopted to classify different pieces of observation information, then multi-channel weighted multi-scale permutation entropy fusion calculation is utilized to fuse different types of monitoring information, the structure operation state is monitored through changes of an entropy curve after fusion, the structure operation state can be rapidly obtained, and the structure can be protected in a targeted mode.

Description

technical field [0001] The invention relates to the technical field of structural operation state monitoring in water conservancy and hydropower projects, in particular to a hydraulic structure operation state monitoring system based on time series clustering fusion. Background technique [0002] During the service process of the hydraulic structure, it is easy to have different degrees of abnormal problems, which may even affect the safe operation of the entire water conservancy project. In view of the complex and changeable environment in which hydraulic structures are located, and the manifestations of different operating states are also different, a single monitoring quantity cannot achieve the purpose of comprehensively analyzing structural safety. Therefore, in order to comprehensively evaluate the operation status of hydraulic structures, it is necessary to arrange a large number of measuring points on different parts of the structure and different observation items. ...
