A bridge structure safety status monitoring system

Abstract

The invention provides a bridge structure safety state monitoring system, which is characterized in that it includes: a sensing subsystem, a signal acquisition and storage subsystem, a signal processing subsystem, a signal communication subsystem and a safety evaluation subsystem; The sensing subsystem monitors the response of the bridge structure under external excitation through sensors or measuring instruments; the signal acquisition and storage subsystem is used to collect various information monitored by the sensing subsystem and store various information In the storage space; the signal processing subsystem includes multiple types of signal processing units, which are used to detect and obtain various abnormal signals; the safety evaluation subsystem is used to evaluate the damage state of the bridge structure, and then generate a bridge structure health inspection report . The bridge structure safety state monitoring system of the present invention realizes real-time monitoring of the health and safety state of the bridge structure, and provides scientific basis for bridge management and maintenance decision-making.

Description

technical field [0001] The invention relates to the technical field of bridge structure monitoring, in particular to a bridge structure safety state monitoring system. Background technique [0002] In order to ensure the safety and durability of large-scale bridge structures, the health status of the bridge can be known in time through appropriate monitoring methods, especially the hidden damage that may endanger the safety of the bridge can be found at an early stage, which will play a vital role in ensuring the safety of the bridge. It plays an important role and also provides the necessary basis for bridge maintenance and reinforcement, which can save bridge maintenance and reinforcement costs and avoid the inconvenience and loss caused by frequent overhaul and traffic closures. Summarizing the past experience and lessons, a long-term safety monitoring system and damage identification control system should be added during the construction of the project to provide reliabl...
