Comprehensive evaluation and intelligent operation and maintenance method for deep underground subway station

Abstract

A comprehensive evaluation and intelligent operation and maintenance method for a deep underground subway station is characterized by comprising the following steps: step 1, establishing a comprehensive evaluation index system for the operation and maintenance state of the deep underground subway station; step 2, based on the index system set in the step 1, collecting and constructing a monitoring data sample library and constructing a neural network, and adjusting parameters through training to optimize the network; and step 3, evaluating the current situation of the operation and maintenance state of the deep underground subway station and predicting the operation and maintenance state of the deep underground subway station by using a neural network, so that the future development situation of the operation and maintenance state of the deep underground subway station can be predicted, the time of adjusting and maintaining the deep underground subway station is guided, and intelligent operation and maintenance and proactive disaster prevention and reduction of the deep underground subway station are realized.

Description

technical field [0001] The invention relates to a comprehensive evaluation and intelligent operation and maintenance method of a deep underground subway station. Background technique [0002] With the acceleration of urbanization in our country, the population density of major cities has increased sharply, which has brought enormous pressure to the existing transportation systems of cities. Because of its fast running speed, large traffic capacity, low energy consumption, small land occupation, low pollution, safety, and punctuality, the subway has gradually become an important solution to the current problems of urban public transportation such as single structure, lagging development, and severe morning and evening peak congestion. means. However, since the shallow underground space has been fully developed and various facilities are crowded, the future subway construction will gradually expand to the deep underground space. Among them, the deep underground subway statio...

AI Technical Summary

Problems solved by technology

[0004] (1) Traditional evaluation methods are more inclined to monitor a single element, ignoring the correlation between various elements, and cannot fully reflect the overall operation and maintenance status of underground stations;

[0005] (2) The traditional evaluation method has problems such as poor operability and poor pertinence in the selection of evaluation indicators, and cannot accurately locate the risk source;

[0006] (3) The traditional operation and maintenance method only deals with the current state of the station, but lacks the analysis and prediction of the future situation, so the response to disasters lags behind
