Railway sound barrier detecting device and working method thereof

Abstract

The invention provides a railway sound barrier detecting device and a working method thereof. The railway sound barrier detecting device comprises a processor, and a first laser vision sensor and a second laser vision sensor respectively connected to the processor and located on a running train; the first laser vision sensor and the second laser vision sensor are spaced apart at a preset distance;the first laser vision sensor is used for collecting first distance data between one of position points of railway sound barriers and the first laser vision sensor; the second laser vision sensor isused for collecting second distance data between the position points and the second laser vision sensor; the processor is used for comparing the difference between the first distance data and the second distance data with a preset value, and when the difference between the first distance data and the second distance data is greater than the preset value, an alarm signal is sent. The railway soundbarrier detecting device can achieve automatic detection of the high-speed railway sound barriers, improve detection efficiency and detection quality, and save the detection cost.

Description

technical field [0001] The invention relates to the technical field of sound barrier detection, in particular to a railway sound barrier detection device and a working method thereof. Background technique [0002] At present, in the construction of high-speed railways in my country, sound barriers are usually used to reduce the impact of noise on the surrounding environment. As an outdoor building, the high-speed rail sound barrier has been attacked by natural environments such as wind and rain for a long time. Its structural parts may rust and corrode, and the rubber strips may age and fail. At the same time, because the sound barrier of the high-speed rail is close to the center of the track, when the high-speed rail passes at high speed, the transient fluctuating wind load will have a significant impact on the sound barrier. The connectors are loose and fall off, and the unit board is pulled apart and damaged. Taking the Beijing-Shanghai high-speed railway as an example...

AI Technical Summary

Problems solved by technology

[0011] (1) When the fastening structure of the sound-absorbing plate is partially loose, only the strong airflow generated by the high-speed passing of the train (300km / h) will cause the swing that the human eye can perceive. It is difficult to find specific problems, and it is easy to overlook potential hidden dangers

[0012] (2) In some bridge sections, the fastening structure is installed on the outside of the barrier, and there is no condition for direct inspection of some connecting structures. Under static conditions, it is impossible to confirm whether there is a risk of loosening
