Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] Please refer to Figure 1 to Figure 3 , a method for monitoring and early warning of overloading and overturning of a single-pier overpass based on comprehensive perception, including the following steps:

[0034] The traffic load monitoring unit collects the load information of the traffic vehicles driving on the bridge in real time, obtains the load parameters, and processes the load parameters into load data through edge computing;

[0035] The bridge deflection and deformation monitoring unit collects the deflection and deformation of the bridge in real time to obtain the first geometric parameter, and processes the first geometric parameter into the first geom...

Abstract

The invention discloses a single-pier overpass overload and overturning monitoring and early warning method based on comprehensive perception, which comprises the following steps: a traffic load monitoring unit obtains load parameters, and processes the load parameters into load data through edge calculation; a bridge deflection deformation monitoring unit obtains a first geometric parameter, and the first geometric parameter is processed into first geometric data through edge calculation; a bridge relative displacement monitoring unit obtains a second geometric parameter, and the second geometric parameter is processed into second geometric data through edge calculation; a bridge overturning risk monitoring unit obtains a third geometric parameter, and the third geometric parameter is processed into third geometric data through edge calculation; a bridge support counter-force monitoring unit obtains counter-force parameters, and the counter-force parameters are processed into counter-force data through edge calculation; and a cloud platform calls and analyzes the data and selects whether to give an alarm or not. The invention is applied to 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...
