Abstract
The present invention discloses a bridge structural safety monitoring system and a bridge structural safety monitoring method. The method includes the steps of capturing an image of a monitoring area of a bridge to create a standard image of the bridge operated at normal conditions, capturing images of the monitoring area of the bridge continuously to obtain monitoring images, comparing the standard image with the monitoring image to obtain a displacement correlation coefficient of the monitoring area of the bridge, and transmitting the displacement correlation coefficient to a central console, such that the central console can determine the using condition of the bridge according to the displacement correlation coefficient.

15. A bridge structural safety monitoring method, comprising the steps of:
-
using an imaging optical system module to obtain at least one standard image of at least one monitoring area of a bridge at a normal operation condition; using the imaging optical system module to take photos of each monitoring area continuously to obtain a plurality of monitoring images of the monitoring area; using an image correlation computing module and an image data comparison method to compare the standard image with each the monitoring image, so as to obtain a displacement correlation coefficient of a relative displacement among structures of the bridge; and
transmitting the displacement correlation coefficient to a central console;
wherein if the central console evaluates the displacement correlation coefficient has reached a critical deformation value, an early-warning system installed to the central console will issue a warning signal to the bridge and wherein if the central console evaluates the displacement correlation coefficient is abnormal, the central console will drive the imaging optical system module to be switched from a data monitoring mode into an image monitoring mode, and the data monitoring mode transmits the displacement correlation coefficient to the central console, and the image monitoring mode transmits the monitoring image to the central console. - View Dependent Claims (16)
