Bridge safety operation monitoring and management system

Abstract

The invention discloses a bridge safety operation monitoring and management system. The system includes a sensing unit which collects and obtains response data of a bridge structure in real time, an analyzing unit which processes and analyzes the response data of the bridge structure, an application unit which provides a user with several functions and services according to processed and analyzed data, a display unit which displays output data in the form of a graph and a report to a bridge manager, and a database and data management unit for storing and managing the data of each unit. The units transmit data and information to each other through a transmission unit, collect data and monitor influence on the performance of the bridge structure in real time, identify existing defects and quality decay of the bridge structure in time, and evaluate and analyze potential development thereof in current environmental conditions and potential threat thereof to safe operation of the bridge structure. The system provides real-time, regular and non-regular safety status information services of the bridge structure for related institutions, and provides scientific basis for decision-making of maintenance needs and measures, etc.

Description

technical field [0001] The invention belongs to the technical field of bridge health monitoring and management, and in particular relates to a bridge safety operation monitoring and management system. Background technique [0002] With the rapid development of my country's expressways and the completion of all 12 national highways in the "five vertical and seven horizontal lines", the development focus of the highway industry will gradually shift from "new construction" to "management and maintenance". However, in recent years, due to the significant effects of factors such as overloading, collisions, illegal operations, natural disasters or environmental changes, the number of dangerous bridges in my country has remained high, and major infrastructure safety accidents at home and abroad have occurred frequently. In addition, 40% of the bridges in our country were built in the 1990s and before, and the concentrated exposure areas of bridge diseases are concentrated 20-30 yea...

Problems solved by technology

[0003] However, the existing bridge maintenance management system (CBMS) mainly focuses on file management, status registration, evaluation analysis, status prediction, etc. of existing bridges, and its data acquisition is still dominated by traditional manual inspections, while 56% of the evaluation results made by manual inspection are inappropriate; in addition, the bridge maintenance work is basically still in the establishment of technical files, cleaning bridges, dredging drain pipes, repairing damaged railings and bridge deck pavement, which cannot meet the actual needs. engineering requirements

[0004] At present, the bridge health monitoring system is an effective solution for bridge supervision recognized at home and abroad. However, the existing bridge health monitoring system is difficult to analyze due to the incompleteness of the measurement data determined by the system scale. The lag in processing and analysis research, as well as the poor stability of the system itself, insufficient anti-interference and durability, and high professionalism make it difficult to guarantee its life, which in turn limits the application of its system
