Embodiment 1

[0022] In this example, see figure 1 and figure 2 , a system for positioning and automatically detecting segments in a tunnel, including a positioning mechanism and an automatic detection system, the automatic detection system including an RFID UHF reader 22, a camera 23, a controller 24 and a segment information detection software system 25. Set a unique RFID tag 21 on each segment in the tunnel in advance, and deliver the RFID UHF reader 22 and camera 23 to the position of the target tunnel segment corresponding to the information to be collected through the positioning mechanism at the same time , the RFID UHF reader-writer 22 reads the RFID detection information from the RFID tag 21 on the target tunnel segment, and the camera 23 obtains the image information from the target tunnel segment, and then the RFID detection information of the collected target tunnel segment and image information are sent to the controller 24 through wireless data transmission, and the controll...

Embodiment 2

[0027] This embodiment is basically the same as Embodiment 1, especially in that:

[0028] In this embodiment, the telescopic length of the pitch swing link 11 is adjusted through a screw transmission mechanism. The screw transmission mechanism is composed of a screw rod and a nut meshing with each other, adopts trapezoidal thread, and makes the thread rise angle smaller than the friction angle, so that the positioning mechanism can adjust the length of the pitch swing rod 11 through the self-locking of the screw transmission mechanism during intermittent work. This embodiment adopts a conduction screw, which mainly transmits motion and has high motion precision, so that the telescopic adjustment mechanism of the pitch swing rod 11 works intermittently, and realizes stable operation through self-locking of the mechanism.

Embodiment 3

[0030] This embodiment is basically the same as the previous embodiment, and the special features are:

[0031] In this embodiment, the acquisition function of the RFID UHF reader 22 in different directions is driven and controlled by a separate motor to achieve a full range of 360° rotation and effective positioning of the system.

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 ...
