Vehicle-mounted subway tunnel disease data automatic acquisition system

Abstract

The invention relates to a vehicle-mounted subway tunnel disease data automatic acquisition system which comprises an image acquisition device, a distance measurement instrument, a motor assembly, a central control main board, a storage battery power supply, a lighting device, a mounting bracket, an encoder, a main control computer and a flat-bed trailer. The central control main board is respectively connected with the image acquisition device, the distance measurement instrument, the motor assembly, the encoder and the main control computer; the motor assembly is connected with the distance measurement instrument; the lighting device is connected with the storage battery power supply; and the mounting bracket and the lighting device are arranged on the flat-bed trailer. When the vehicle-mounted subway tunnel disease data automatic acquisition system works, the central control main board controls the image acquisition device to acquire a subway tunnel image in real time, the motor assembly drives the distance measurement instrument to measure a real-time position of the image acquisition device and records the real-time position, the encoder calculates a running distance of the flat-bed trailer and acquires current longitudinal positioning data of the image acquisition device and the central control main board reads the data and then sends the data to the main control computer. Compared with the prior art, the vehicle-mounted subway tunnel disease data automatic acquisition system has the advantages of information acquisition accuracy, high disease detection working efficiency and the like.

Description

technical field [0001] The invention relates to an automatic data collection system, in particular to a vehicle-mounted automatic collection system for subway tunnel disease data. Background technique [0002] With the increase of tunnel operation time, almost all tunnel structures are exposed to varying degrees of damage, mainly including the following categories: leakage, lining corrosion, lining crack damage, tunnel freezing damage, etc., which affect the safety of operation. In order to grasp the occurrence and development of tunnel diseases in a timely manner, the tunnel operation maintenance and management departments usually adopt regular or special disease investigation activities to collect disease information of tunnel structures, and make maintenance decisions based on the collected tunnel disease information. [0003] Although the current automation, informatization, and digital disease investigation equipment and methods are gradually being valued and applied, d...
