Monitoring and early warning method for overloading and overturning of Dudun overpass based on comprehensive perception

Abstract

The invention discloses an overload and overturning monitoring and early warning method for single-pier overpass bridges based on comprehensive perception, which comprises the following steps: the traffic load monitoring unit obtains the load parameters, and processes the load parameters into load data through edge calculation; the bridge deflection and deformation monitoring unit obtains the first A geometric parameter, the first geometric parameter is processed into the first geometric data through edge computing; the bridge relative displacement monitoring unit obtains the second geometric parameter, and the second geometric parameter is processed into the second geometric data through edge computing; the bridge overturning risk monitoring unit The third geometric parameter is obtained, and the third geometric parameter is processed into the third geometric data through edge computing; the bridge support reaction force monitoring unit obtains the reaction force parameter, and the reaction force parameter is processed into reaction force data through edge computing; the cloud platform separately adjusts Take and analyze the above data, choose whether to call the police or not. The invention is applied in the technical field of bridges.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to an overload and overturning monitoring and early warning method for single-pier overpass bridges based on comprehensive perception. Background technique [0002] The safety condition of bridge structures has been a particular concern of the public for many years. Modern large-scale overpasses are important nodes of urban traffic trunk roads, have a major impact on the development of urban transportation, and are symbols of national and regional economic development and technological progress. However, many urban overpasses at home and abroad have different hidden dangers at present. Wherein, the single column pier overpass is a kind of overpass with only one pier column as the pier under the cross section of the superstructure. Due to the simple structure, small footprint, strong adaptability and good economy, the single-pier overpass has been built and used in large numbers in...
