Control system in damping bridge

Abstract

The present invention belongs to the technical field of bridge damping, and discloses a control system in a damping bridge. The control system comprises a camera monitoring module, a pressure detection module, a vibration detection module, a central control module, a cloud service module, a data assessment module, a data storage module, an alarm module and a display module. The control system employs the cloud service module to greatly improve the speed for analysis and processing of the bridge vibration monitoring data and improve the monitoring efficiency; and moreover, the control system employs the data assessment module to perform mathematical statistics of detection data and make scientific and accurate determination so as to avoid generation of a condition that data processing is not accurate caused by man-made subjective factors.

Description

technical field [0001] The invention belongs to the technical field of bridge damping, in particular to a control system in a damping bridge. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, bank pr...

Problems solved by technology

[0005] The data processing speed of the control system in the existing shock-absorbing bridge is slow, which greatly affects the monitoring of bridge vibration data, resulting in a greatly reduced bridge safety; at the same time, the monitoring data is judged by humans, which is subjective and inaccurate

[0006] In the process of safety evaluation of seismic-absorbing bridges, there are many factors that affect its safety performance. Some factors can be quantified, while some factors can only be analyzed qualitatively. There are correlations between various factors and affect the safety of seismic-absorbing bridges. The main factor is the defect, the detection process is very complicated, and the quantitative results are not accurate, these situations bring great difficulties and doubts to its safety assessment

The current safety assessment of shock-absorbing bridges mostly adopts a single-angle evaluation method, and draws a conclusion from the theoretical aspect whether the shock-absorbing bridge can work safely, and cannot comprehensively solve the problem of its safety degree

The specific analysis is as follows: the detection and quantification of defects are inaccurate; the single-angle evaluation method relies too much on field data, and cannot comprehensively consider all the main factors affecting the safety of seismic bridges, and clarify the relationship between each impact and the actual situation Inconsistent; the result of the assessment is only a theoretical conclusion on whether it can work safely, and it cannot solve the problem of safety level, let alone dynamically monitor the changing trend of disasters, so as to better and more accurately detect disasters in time and prevent them in advance

The above problems will make the safety assessment result unsatisfactory, and the result is often: the theoretical result of the assessment is still within the safety permit, but in fact the shock-absorbing bridge has failed and cannot be used
