Bridge turning method and system based on real-time monitoring of bridge turning posture

The invention relates to a bridge swivel method and system based on real-time monitoring of bridge swivel postures, and relates to the technical field of bridge construction, and the method comprises the following steps: arranging a plurality of 360-degree prisms on a longitudinal center line of a bridge, sending acquisition instructions to a total station at intervals, and acquiring space coordinates of the plurality of 360-degree prisms. And constructing a bridge direction vector according to the space coordinates, and obtaining rotation attitude data. And obtaining the time length of the interval, the acquisition instruction and the control instruction according to the rotation attitude data. And controlling the bridge to turn according to the control instruction. According to the invention, the spatial attitude, angular velocity and linear velocity of the bridge in the bridge swivel construction process can be monitored in real time, so that corresponding measures can be taken in time when the bridge swiv
