| description | The invention relates to a bridge monitoring device. The device comprises a plurality of identical measuring sensors arranged on a bridge, and a plurality of grating strain sensors and displacement sensors are arranged at equal intervals on the to-be-tested bridge, and a grating temperature compensation sensor is arranged at a part of the average temperature of the bridge. A data acquisition device is connected with the grating strain sensors, the displacement sensors and the grating temperature compensation sensor in a wired or wireless manner, and the data acquisition device collects the changes of the center wavelengths of the strain sensors during different bridge loads, and transmits the collected data to a data processing device. The data processing device calculates the strain and/or displacement of the bridge based on the collected data to determine whether the bridge is damaged or not according to the strain and/or deflection of the bridge. The device saves a monitoring sensor, reduces the cost, and |
