Highway and railway dual-purpose bridge line shape automatic measuring system

The utility model provides a highway and railway dual-purpose bridge line shape automatic measuring system. The system comprises GNSS (Global Navigation Satellite System) receivers which are arranged at monitoring points of a highway bridge floor and are used for positioning, inclinometers which are used for measuring inclination angles of mounting brackets of the GNSS receivers, laser rangefinders which are arranged on a railway bridge floor below the monitoring points and are used for measuring the distance between the railway bridge floor and the highway bridge floor, and a communication unit, and the transmitting module is used for transmitting output data of the GNSS receiver, the inclinometer and the laser range finder to the cloud server. According to the utility model, by measuring the linear data of the bridge floor in real time, the deformation rule of the bridge and the influence rule of the external environment on the line shape of the bridge can be known in time, and powerful data support can be
