Abstract

The invention discloses a system for positioning and automatically detecting segments in a tunnel, which includes a positioning mechanism and an automatic detection system. The automatic detection system includes an RFID ultra-high frequency reader, a camera, a controller and a segment information detection software system , set RFID tags on the segments in the tunnel in advance, and send the RFID UHF reader and camera to the target tunnel segment position corresponding to the information to be collected through the positioning mechanism, and the collected RFID detection information and image information are transmitted through wireless data Send it to the controller, and the controller analyzes and processes the information data collected by the automatic detection system by calling the information detection software system, and finally obtains the positioning of the tunnel segment and the processing results of the automatic detection. The invention realizes the automatic collection of high-position segment information in the tunnel, records the position and state of each segment at the same time, can timely and accurately locate the fault position when a fault occurs, and improves the management and maintenance capabilities of tunnel facilities.

Description

technical field

[0001] The invention relates to a tunnel detection system, in particular to a tunnel segment detection system, which is applied in the field of tunnel fault detection. Background technique

[0002] The shield segment is the main assembly component of shield construction and the outermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. Therefore, it is very important to detect the status of segments in time for tunnel safety, and the current detection methods mainly have the following two major problems:

[0003] On the one hand, the height of the general tunnel is 6-7 meters, so the installation position of the detection chip on the segment is relatively high, and it is difficult for traditional handheld devices to achieve detection at this height. Moreover, manual detection is labor-intensive and inefficient.

[0004] On the other hand, the positioning problem in tunnel detection is also ...
