Abstract

The invention relates to a support vector machine-based compensation method for missing data in a mine fiber grating monitoring system, which belongs to the compensation method for missing data in monitoring systems. Including step 1: collecting data from the sensing equipment of the mine fiber grating monitoring system; step 2: expressing and preprocessing the monitoring data collected by the fiber grating sensing equipment in time series; step 3: selecting and constructing the kernel of the support vector machine function; step 4: select and determine the hyperparameters of the support vector machine; step 5: construct the kernel matrix according to the determined kernel function, loss function and penalty parameters, and use the optimization algorithm to obtain the optimal parameter value of the support vector machine; step 6: establish the support vector The machine regression function model is used to perform fitting regression analysis on the data to obtain the missing data compensation result and realize the missing data compensation work. The invention can compensate the missing monitoring data, improve the monitoring data, make the data closer to real and reliable, and ensure the safe production, construction and stability of the mine.

Description

technical field [0001] The invention relates to a method for compensating missing data in a monitoring system, in particular to a method for compensating missing data in a mine optical fiber grating monitoring system based on a support vector machine. Background technique [0002] In the process of coal mine production, due to the influence of mining, the roadway and the roof of the working face are in an unstable state. With the continuous increase of the mining depth of the coal mine, the mine pressure of the coal mine and the safety pressure of the coal mine are more obvious, and the disasters caused are also increasing. The more serious it is, if the support measures are not taken in time, accidents such as roof caving, roadway deformation, impact mine pressure, gas explosion, coal mine water inrush, coal mine fire and other accidents will occur, which have caused huge losses to my country's coal mining industry and seriously affected It has ensured the safety of employees...
