Bridge safety monitoring system and method based on BIM

Abstract

The invention provides a bridge safety monitoring system and method based on a BIM, and the system comprises an information collection system and a BIM bridge information management system. The information collection system employs a sensor and a long-distance RFID to achieve the collection of the state information and position information of a component, and the information is uploaded to a cloud server through a network. The cloud server is connected to the BIM bridge information management system, thereby achieving the timely updating of the information. All components in the BIM bridge information management system are provided with preset early-warning values. When a test value exceeds the preset early-warning value, the system gives a prompt. The system enables the BIM technology to be reasonably integrated with the monitoring technology, can achieve the subsequent high-efficiency safety monitoring of the bridge, and is used for the visualized and digitalized safety monitoring of the bridge.

Description

technical field [0001] The present invention relates to a bridge information management system in the field of electronic information technology, in particular to a BIM-based bridge safety monitoring system and method. Background technique [0002] The core of BIM (Building Information Modeling) technology is to establish a virtual three-dimensional model of architectural engineering in the computer, and at the same time use digital technology to provide a complete and consistent architectural engineering information library for this model. The information base not only contains geometric information, professional attributes and state information describing building components, but also contains state information of non-component objects (such as space and motion behavior). With the help of this 3D model rich in construction engineering information, the integration of construction engineering information is greatly improved, thus providing a platform for engineering informat...

Problems solved by technology

Although the patent applies the BIM model to bridge monitoring, it uses an intelligent manual inspection module, which cannot realize real-time and continuous monitoring of the bridge. At the same time, the collected data is not processed, resulting in digital signals after digital-to-analog conversion. It can no longer reflect the problem of the signal characteristics generated by the actual structure, so it is impossible to realize efficient and accurate safety monitoring of the bridge
