Bridge safety polling system and diagnostic method based on traditional Chinese medicine methodology

Abstract

The invention discloses a bridge safety polling system and a diagnostic method based on a traditional Chinese medicine methodology. The bridge safety polling system comprises an information acquisition unit and a central processing unit, wherein the information acquisition unit is used for continuously acquiring bridge floor morphological images, vibration time course characteristic signal data and structural audio time course characteristic signal data; the central processing unit is used for receiving data information transmitted by the information acquisition unit and comprehensively analyzing and judging a bridge safety state. According to the invention, bridge floor face, dynamic response and sound distribution data of a bridge is acquired by a monitoring system, which is similar withlooking, listening, asking and feeling the pulse in the traditional Chinese medicine theory; the safety state of the bridge is comprehensively analyzed for replacing the existing structural safety inspection work; polling efficiency can be effectively improved; artificial participation intensity is reduced; inspection can be implemented in an omnibearing mode in shorter time; not only can surfacedefects of the structure be directly observed and found after image information returned by the system is analyzed and processed by an image morphological algorithm, but also according to a rule thatdiseases endangering structural safety necessarily cause changes of the structural morphology, analysis comparison of bridge face (structural appearance) change monitoring is obtained by each inspection to discriminate safety of the current structure.

Description

technical field [0001] The invention relates to the field of civil engineering detection, which combines sensing technology, information engineering, mechanical engineering and artificial intelligence, and in particular relates to a bridge safety inspection system and diagnosis method based on traditional Chinese medicine methods. Background technique [0002] Bridges are the main components of road traffic. Once they are completed and put into use, in addition to the continuous degradation of the properties of the construction materials during their service period, they will inevitably be subject to repeated loads of vehicle loads, environmental loads, earthquake loads, and human factors. The effects of different degrees of damage to the structure, material aging and damage accumulation lead to continuous degradation of structural performance, which may lead to sudden local or overall failure disasters. Therefore, bridge safety testing equipment and diagnostic methods that ...

Problems solved by technology

Such a monitoring method is basically a direct measurement of a structure and a system. The advantage is that it is possible to grasp the information of the structure at all times, but it has high system construction costs, human and financial resources, low confidence in the returned data, and data drift and noise. The phenomenon is serious, massive data is difficult to deal with, and only the limited information at the limited sensor installation points on the energy measurement structure, etc., and the service life of the monitoring components contained in the system is generally 5-10 years, while the normal service life of the bridge is 50 years -100 years, the monitoring system is difficult to meet the long-term use requirements of structural health monitoring, and it is difficult and expensive to replace the original monitoring components and maintain the normal operation of the system

[0005] To sum up, the methods, means, equipment, personnel and effective detection frequency of bridge structure safety monitoring currently used are far from meeting the actual needs of infrastructure. Therefore, it is urgent to find a bridge safety inspection with a large amount of Economical, convenient, credible, holographic and in line with the future development trend of bridge safety testing equipment and diagnostic methods to effectively grasp the safety status of bridges and prevent disasters and accidents
