Problems solved by technology

Its shortcomings: the manual inspection method has a relationship between the fault detection rate and the state of the person, and it is prone to missed inspections; for long tunnels, the manual inspection time is long, and there is not enough skylight time for the inspection personnel
Although the devices of the above two utility model patents can meet certain requirements for use, they have disadvantages: they are fixedly installed somewhere on both sides of the tunnel, the monitoring area is small, and they do not have tunnel section detection, roadbed settlement detection, Functions such as lining detachment, ancillary facility displacement, drop detection, etc.
Its shortcomings: the invention is only aimed at the system architecture of the collection, transmission, real-time display and timely warning of a single parameter of tunnel structural deformation, not a specific method for data collection

Abstract

The invention discloses an intelligent inspection device of a railway tunnel and an application method thereof. The inspection device comprises a control mainboard, a machine case, an auxiliary light source, a digital camera and an alarm apparatus, wherein special software is arranged inside the control mainboard; the special software analyzes, processes and stores digital pictures shot by the digital camera; the alarm apparatus works when the processing result exceeds the preset range; the control mainboard transmits the processing result to an external computer or a remote server when a communication interface in the control mainboard is connected with the external computer or the remote server; remote monitoring and real-time alarming in tunnel inspection can be achieved when the communication interface in the control mainboard is kept in connection with the external computer or the remote server. The application method of the inspection device comprises the processing steps: automatically walking on a special track of the tunnel; transmitting the digital picture shot by the digital camera and related information obtained by the sensor to the computer to analyze and process. The device disclosed by the invention is scientific and reasonable in structure and configuration, unattended in operation, and wide in inspection range.

Description

technical field [0001] The invention relates to an intelligent inspection device for railway tunnels and a method for using the same. Background technique [0002] During the long-term operation of railway tunnels, there will be problems such as section deformation, subgrade settlement, lining falling off, and auxiliary facilities shifting and falling. At present, the main way to detect the operation status of the tunnel is to rely on manual inspection, that is, during the skylight period of train operation, inspection personnel enter the tunnel to test with the naked eye and simple and limited tools and instruments. Its shortcomings: the manual inspection method has a relationship between the fault detection rate and the state of the person, and it is prone to missed inspections; for long tunnels, the manual inspection time is long, and there is not enough skylight time for the inspection personnel. [0003] Chinese utility model patent "ZL201320253220.6 Tunnel monitoring ...
