Comprehensive detection device and method for safe operation environment of tunnel train

Abstract

The invention discloses a comprehensive detection device for a safe operation environment of a tunnel train. The comprehensive detection device comprises an image acquisition unit, a tunnel inspectionunit and a system control unit, wherein the image acquisition unit conducts image acquisition through various detection capture units; the tunnel inspection unit conducts targeted detection on the part of abnormal appearance in a tunnel based on analysis and processing results of images collected by the image acquisition unit; the system control unit is composed of a control module, a storage module and an identification module, and is used for analyzing, processing and identifying image data and storing results in a local hard disk. The invention further discloses a detection method adoptingthe detection device. When the train runs in the tunnel, the detection device can be started to comprehensively detect overhead lines, the tunnel, a steel rail and a track board, a previous manual inspection or special inspection van inspection mode is abandoned, the detection efficiency is improved to a large extent, and the detection time is shortened.

Description

technical field [0001] The invention relates to a device for detecting a safe running environment of a train, in particular to a device for detecting a running environment used in a tunnel environment. Background technique [0002] Existing methods for detecting the safe operating environment of trains include the following: [0003] The first is the pantograph-catenary detection method, which usually collects data in the tunnel by video recording. Because a large amount of useless data is generated, the data processing volume of the system increases dramatically, and intelligent identification cannot be completed in real time, and the location of the disease cannot be accurately located. The positioning information is inaccurate. Maintenance efficiency cannot be improved, and labor costs cannot be saved. [0004] The second is the laser detection method. By using the moving laser scanning data acquisition technology, the laser scanner is installed on the corresponding dete...

AI Technical Summary

Problems solved by technology

[0007] Pantograph-catenary capture, when collecting data at this stage, there is no intelligent recognition and data collection technology, and the equipment has been continuously captured when starting up, collecting a large amount of useless data, which affects subsequent intelligent recognition, the huge amount of data is slow, the transmission speed is slow, and the local memory space is too large

[0008] Laser detection, laser detection is mainly used for section scanning and monitoring tunnel section convergence, its detection accuracy is relatively low, and it cannot meet the requirements of tunnel crack detection

[0009] For area array visual inspection, the area array camera is mounted on the vehicle to collect images inside the tunnel. It cannot fully capture the image of the entire tunnel, and there will be frame loss and some information will be missed.

Especially for the detection of discontinuous short cracks is not good

Even through image correction, image enhancement, image recognition and other methods, the effect cannot be achieved
