Embodiment Construction

[0028] Referring to Figure 1, the structural health monitoring and information management system (SHM&IMS) of this application is researched and developed based on modern information technologies such as geographic information system (GIS), computer network and database.

[0029] The structural health monitoring and information management system consists of the following 6 subsystems:

[0030] 1. Sensor subsystem (SS, Sensory Subsystem): used to sense various structural health indicators of monitored buildings such as bridges and dams; the types of sensors included in the sensor subsystem (taking bridge monitoring as an example, there are seven types in total ): Displacement transducers, anemometers, accelerometers, strain gauges, temperature sensors, etc.

[0031] 2. Data Acquisition Subsystem (DCS, Data Acquisition Subsystem): connected to the sensor subsystem, used to collect digital or analog signals from various sensors, save the digital signals, and convert the analog si...

Abstract

A method and information management system of structure health comprises transducer subsystem, data collection subsystem, data management subsystem, data storage device subsystem, diagnosis and analysis subsystem, real time monitor and data query subsystem. It is featured as setting up said data management subsystem based on commercial databank management system, enabling diagnosis and analysis subsystem to carry out parameterization by utilizing monitored building 3-D space model set based on 3-D GIS technique in order to obtain multiple mode parameter.

Description

technical field [0001] The invention relates to the field of structural health monitoring of building structures such as bridges, in particular to a structural health monitoring and information management system and a method thereof. Background technique [0002] The service life of major projects such as bridges and dams lasts for decades or even hundreds of years. The coupling of environmental erosion, material aging, long-term effects of loads, fatigue effects, and catastrophic effects will inevitably lead to structural and system failures. The accumulation of damage and the attenuation of resistance will reduce the ability to resist natural disasters and even normal environmental effects. In extreme cases, catastrophic accidents will occur. Therefore, in order to ensure the health of the structure of the above-mentioned major projects, that is, safety, integrity, applicability and durability, it is necessary to monitor and evaluate its health status, that is, the service...
