Bridge structure safety state monitoring system

Abstract

The invention provides a bridge structure safety state monitoring system. The system is characterized by comprising a sensor subsystem, a signal collection and storage subsystem, a signal processing subsystem, a signal communication subsystem and a safety evaluation subsystem; the sensor subsystem monitors response of a bridge structure under the external excitation through a sensor or a measurement instrument; the signal collection and storage subsystem is used for collecting various classes of information monitored by the sensor subsystem, and storing the information in a storage space; thesignal processing subsystem comprises multiple classes of signal processing units for detecting various classes of abnormal signals; the safety evaluation subsystem is used for evaluating a damage state of the bridge structure, and then generating a bridge structure health detection report. The bridge structure safety state monitoring system disclosed by the invention realizes the monitoring on the health safety state of the bridge structure in real time, and provides scientific evidence for the management and maintenance decision of the bridge.

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...
