TUNNEL AUTOMATIC MONITORING AND MEASUREMENT EQUIPMENT AND METHOD BASED ON FIXED-POINT TOUR MEASUREMENT

A tunnel automatic monitoring and measuring equipment and method based on fixed-point tour measurement are provided. The equipment includes a monitoring trolley that can move freely in the longitudinal direction of the tunnel, multiple automatic tracking and identification devices are set on the monitoring trolley, the automatic tracking and identification device is connected to the background processing system telecommunication; a monitoring points with reflective markings are arranged on the surface of the tunnel support structure, under the cooperation of the monitoring trolley and the automatic tracking and identification device, the reflective markings set on the tunnel support structure can be automatically measured at the fixed point to obtain the coordinate information of the relevant monitoring points; then, the deformation data of the support structure required in the construction process are extracted by coordinate information calculation.
