Bridge safety monitoring device and method based on laser gyroscope

Abstract

The invention discloses a bridge safety monitoring device and method based on a laser gyroscope, belongs to the field of safety detection, and is characterized in that the bridge safety monitoring device comprises a laser gyroscope which is installed on a bridge to be monitored and used for measuring an angular velocity signal caused by small deformation of the bridge; an acquisition recorder which is connected with the laser gyroscope and is used for acquiring and recording the angular velocity signal output by the laser gyroscope and outputting the angular velocity signal; and a network computer which is connected with the data recorder through a data transmission link and is used for receiving the angular velocity signal and analyzing and extracting structural deformation data of the bridge. The problem that an existing bridge safety monitoring method is inconvenient to construct is solved; real-time safety monitoring for a bridge is realized; and compared with existing local damagedetection based on instruments and equipment and structure health detection based on static measurement data, the bridge monitoring precision is effectively improved.

Description

Technical field [0001] The invention relates to the technical field of safety detection, in particular to a bridge safety monitoring device and method based on a laser gyro. Background technique [0002] Bridges are important transportation infrastructure. In the course of service, the bridge is inevitably affected by factors such as environmental erosion, material aging, load effects, man-made or natural disasters and other factors, resulting in structural damage and potential safety hazards. When these potential safety hazards reach a certain level, they will affect the normal use of the bridge, and even cause catastrophic emergencies, causing heavy economic losses and casualties. Therefore, the use of effective bridge safety monitoring devices and methods to monitor the health of the bridge and provide early warning of bridge damage can improve the efficiency of the safety and health maintenance of the bridge, and to a certain extent prevent the safety of the bridge during se...
