Track deformation monitoring device

The utility model discloses an orbit deformation monitoring device which comprises a client, a server and a plurality of monitoring terminals, the monitoring terminals are arranged on the side face of a light rail, and the monitoring terminals receive satellite signals and send data to the server. The server processes the received satellite data and provides services for the outside, and the client is connected with the server and requests real-time and historical data for online monitoring of light rail deformation. According to the track deformation monitoring device, the client, the server and the monitoring terminals are arranged to form a light rail deformation monitoring network, a plurality of points on a light rail are monitored through the plurality of monitoring terminals, and the server analyzes data uploaded by the plurality of monitoring terminals to judge whether a certain section of the light rail is deformed or not. The client side realizes on-line monitoring of light rail deformation monitori
