Problems solved by technology

[0003] The main sources of decision-making information for existing bridge management and maintenance are manual inspections and non-destructive tests. Manual inspections largely rely on the professionalism of inspectors and are easily affected by climate and environment. Inspections are limited. And the inspection quality is poor, which leads to the lack of scientific, systematic and targeted decision-making methods for bridge management and maintenance

Embodiment 1

[0027] figure 1 It is a flow chart of a bridge health status assessment method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of monitoring and evaluating the bridge health status, and the method can be executed by a bridge health status assessment system. like figure 1 As shown, the method includes the following steps:

[0028] Step 110, acquiring bridge inspection information of the target bridge.

[0029] Wherein, the target bridge may be any bridge, or multiple bridges, or all bridges in the specified area. The advantage of this setting is that it provides a set of health status evaluation methods for multiple bridges, reduces the evaluation cost, and realizes the evaluation of the monitoring status of regional bridge clusters. Bridge inspection information refers to the information recorded during the target bridge inspection, including crack information, damage information, sag information, and corrosion information. ...

Embodiment 2

[0070] figure 2 It is a flow chart of a bridge health status assessment method provided by Embodiment 2 of the present invention. This embodiment is a further refinement of the previous embodiment. The flow chart of the bridge health status assessment method provided by this embodiment is also Including: obtaining the 3D model of the target bridge; determining the building information model of the target bridge based on the 3D scanning technology and the 3D model; The inspection information and structural response information of the target bridge estimate the health status of the target bridge within a set time period; determine the target bridge management and maintenance plan according to the health status within the set time period.

[0071] like figure 2 As shown, the assessment method of the bridge health status includes the following steps:

[0072] Step 210, acquiring a three-dimensional model of the target bridge.

[0073] Wherein, the 3D model refers to the digit...

Embodiment 3

[0105] image 3 A schematic diagram of the results of a bridge health assessment device provided in Embodiment 3 of the present invention, such as image 3 As mentioned above, the evaluation device of the bridge health status includes: a patrol information acquisition module 310, a structural response acquisition module 320, and a health status evaluation module.

[0106] Among them, the inspection information acquisition module 310 is used to obtain the bridge inspection information of the target bridge; the structural response acquisition module 320 is used to obtain the structural response information of the target bridge based on the bridge monitoring system, wherein the structural response information Including one or more items of deflection, temperature, humidity and stress and strain; the health status evaluation module 330 is used to evaluate the health status of the target bridge according to the bridge inspection information and structural response information of th...

Abstract

The invention discloses a bridge health state evaluation method, device, system and equipment. The bridge health state evaluation method comprises the steps of obtaining bridge inspection informationof a target bridge; based on a bridge monitoring system, obtaining structural response information of the target bridge, and the structural response information comprises one or more of deflection, temperature, humidity and stress-strain; and evaluating the health state of the target bridge according to the bridge inspection information and the structure response information of the target bridge.According to the technical scheme provided by the embodiment of the invention, the inspection information and the structure response information of the bridge are integrated, so that the health stateof the bridge is automatically evaluated, and the comprehensiveness, scientificity and accuracy of evaluation are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of bridge monitoring, in particular to a method, device, system and equipment for assessing the health status of a bridge. Background technique [0002] With the development of my country's highway and railway bridges, bridge projects across rivers, straits, and deep mountains and canyons have developed rapidly. At the same time, many existing bridges have gradually entered the maintenance and repair stage. Relevant experts believe that bridges have been used for more than 25 years Then it enters the aging period. According to statistics, 40% of the total number of bridges in my country already belongs to this category, and they all belong to "aging" bridges. And with the passage of time, its number is still increasing, and bridge managers have paid more and more attention to the maintenance of bridges. In order to keep abreast of the working status of bridges, provide early warning...
