Problems solved by technology

In this method, the spatial position of the measuring point is not clear, lacks the geometrical space characteristics, and the user can use it poorly. It is often possible to see the measuring point data, but it is impossible to find out which part of the data reflects the physical change of the three-dimensional structure. It is impossible to accurately locate the measuring points and acquisition equipment, and cannot realize the control of the on-site hardware

Abstract

The invention discloses a large-scale bridge structure health monitoring method based on three-dimensional modeling simulation. The method comprises the following steps: installing a sensor and a collected central station on a bridge; carrying out real time measuring point monitoring to the bridge; transmitting monitoring data to an information control chamber and storing in a server database; establishing a three-dimensional model of the bridge on a GIS platform so as to simulate and display a bridge structure, the each measuring point and real time monitoring information; carrying out a health status assessment to the bridge structure by combining the real time monitoring information and according to a preset assessment standard; carrying out simulation displaying of an assessment result and simulating the health status of the bridge structure; positioning the sensor and the collected central station on the bridge; adjusting an acquisition parameter of the sensor and the collected central station; real-timely feeding back and controlling operations of the on-site sensor and the collected central station. By using the method of the invention, three-dimensional space display of the sensor and acquisition equipment can be performed. Acquisition and control of hardware equipment can be realized through accurate positioning and the current health status of bridge can be simulated and displayed.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for monitoring the health of a large bridge structure based on three-dimensional modeling and simulation. Background technique [0002] The health monitoring system of large-scale bridge structures serves the safe operation status monitoring and maintenance management of bridges. Integrated integrated systems engineering. How to build a user-friendly interactive platform for bridge structural health monitoring system is an urgent problem to be solved. Through this system platform, various data can be displayed to the user in real time according to the demand, and the control and input of the system can be accepted by the user. The content to be displayed includes: the position of the sensor in the bridge, the data content received by the sensor, the bridge information about the health status of the structure. [0003] The current health monitoring system for large bridge s...
