Abstract

The invention discloses a method for completing continuous missing data of dam deformation monitoring, which solves the problem of completing continuous missing data of dam deformation monitoring. Firstly, the continuity loss of deformation monitoring data is pretreated. Secondly, from the angles of global space, global time, local space, local time and semantics, the spatio-temporal similarity and functional similarity of deformation monitoring points are calculated respectively, and the missing data in deformation monitoring data are interpolated globally and locally in space, time and semantics. Finally, a depth neural network model is constructed to complete the continuous missing data in dam deformation monitoring. The preliminary results of the missing data are used as input, and thenonlinear fusion is realized by using the depth neural network representation ability.

Description

technical field [0001] The present invention relates to a continuous data missing complement method, specifically a multi-view deep fusion-based missing data complement method for dam deformation monitoring, which captures complex nonlinear spatio-temporal relationships through a deep neural network to complete dam deformation monitoring The invention provides continuous missing data completion, which belongs to the technical field of data mining. Background technique [0002] A large number of sensors are deployed in the concrete dam, and they cooperate with each other to continuously monitor the real-time state of the dam deformation. The data generated by the sensor has spatio-temporal characteristics, but due to its own hardware, communication errors and severe wireless interference and other influencing factors, a large number of original sensor data are missing, and in extreme cases, continuous data is missing. The lack of these data not only affects real-time monitor...
