Description

Master-slave maintenance-free sound barrier automatic monitoring and alarming device
Technical Field
The invention belongs to the technical field of sound barrier monitoring, and particularly relates to a master-slave maintenance-free sound barrier automatic monitoring and alarming device.
Background
The sound barrier is one of important measures for controlling noise pollution of the high-speed railway, and is widely installed on two sides of a high-speed railway line penetrating through a city. Sound barriers come in a variety of structural forms, with cross-plate metallic sound barriers being the most widely used form of construction, accounting for more than 90% of the total sound barrier. The transverse flashboard type metal sound barrier consists of an H-shaped steel upright post and a transverse metal flashboard between the upright posts. Because the high-speed railway train is influenced by vibration and pneumatic wind pressure generated when passing at high speed for a long time, the problems of loosening bolts, metal fatigue and the like exist, the posture of the H-shaped steel upright post is changed, and potential safety hazards such as falling off of a metal transverse inserting plate are caused, so that the high-speed railway train is threatened to the operation safety of the high-speed railway train.
The existing daily maintenance mode of the sound barrier is manual inspection. The method is mainly used for checking the perpendicularity of the H-shaped steel upright post, whether bolts are loosened, whether a transverse inserting plate falls off or not and the like. The manual inspection mode has the advantages of large workload, low working efficiency, long inspection interval time and serious consequences possibly caused by untimely discovery of problems. In addition, the manual inspection generally has no data retention, is difficult to carry out intelligent analysis, and cannot meet the informatization and intellectualization requirements of modern railway construction, operation and maintenance.
