Automatic control device and control method for tunnel defect detection

Abstract

The invention relates to the technical field of tunnel detecting equipment, in particular to a tunnel disease detecting automatic control device and method. The tunnel disease detecting automatic control device comprises a control system and a data collecting system which are carried on a rail vehicle, the data collecting system comprises a detecting device mounted on a central control module, andthe detecting device comprises a fan-shaped bracket. The fan-shaped bracket is provided with a plurality of tray boxes distributed in a fan shape, the tray boxes are slidably mounted on the fan-shaped bracket, and an industrial area array CCD camera and a laser distance measuring instrument are mounted in each tray box in an integrated mode. The tray boxes are driven by a distance adjusting module to slide on the fan-shaped bracket, and the control system controls the central control module and the distance adjusting module to adjust the positions of all the tray boxes according to the detected data of the laser distance measuring instruments. According to the tunnel disease detecting automatic control device and method, through detecting and feeding back, the positions of the tray boxesare adjusted, and the accuracy and effectiveness of data collecting are greatly improved.

Description

technical field [0001] The invention relates to the technical field of tunnel detection equipment, in particular to an automatic control device and control method for tunnel defect detection. Background technique [0002] During the operation of the subway, apparent defects such as water leakage, cracks, and spalling of the tunnel structure mainly made of concrete materials, as well as deformation of the tunnel section, are unavoidable disease phenomena, and the long-term development of the disease has serious consequences for the safety of the tunnel. irreversible negative effects. Therefore, the maintenance of the tunnel structure in the subway operation is a necessary means to ensure the long-term safe operation of the tunnel. [0003] The position control of the sensor in the detection process directly affects the validity of the detection data collection. At present, most of the sensor positions for defect detection in subway tunnels are set in advance. For different ...

AI Technical Summary

Problems solved by technology

At present, most of the sensor positions for defect detection in subway tunnels are set in advance. For different tunnel cross-section environments, it is often impossible to adjust the position to improve the validity of the data and reduce the difficulty of software analysis.

For example, in the patent CN201510085599.8, the data acquisition of the left and right half of the tunnel is only realized through the rotation of the horizontal rotation axis, and the position of the sensor is not controlled more precisely. After changing the tunnel environment, the error of the device changes, which affects the effectiveness of the collected data. The complexity greatly increases the complexity of the internal processing of the software, thus affecting the collection and analysis efficiency
