Title:
AUTOMATIC TUNNEL MONITORING AND MEASURING DEVICE AND METHOD BASED ON FIXED-POINT ITINERANT MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2023/178837
Kind Code:
A1
Abstract:
Disclosed in the present invention are an automatic tunnel monitoring and measuring device and method based on fixed-point itinerant measurement. The device comprises a monitoring trolley capable of freely moving in a tunnel longitudinally, a plurality of automatic tracking identification apparatuses connected to a background processing system are provided on the monitoring trolley, and several monitoring points attached with reflective identifiers are arranged on the surface of a tunnel supporting structure. Under the cooperation between the monitoring trolley and the automatic tracking identification apparatuses, automatic fixed-point itinerant measurement can be performed on the reflective identifiers arranged on the tunnel supporting structure to obtain coordinate information of related monitoring points, and then deformation data of the supporting structure required in a construction process is extracted by calculating the coordinate information, thereby achieving real-time monitoring in all directions and early warning of the tunnel. The present invention has the advantages of simple structure, low cost, simple operation, low requirement on monitoring personnel, good operation flexibility, high reliability, complete functions and high popularization.
