Problems solved by technology

Visual inspection and steel ruler insertion measurement cannot detect the exact distribution of the middle part of the seam and the seam, while the stripping method is only applicable to the railway under construction, and it is expensive and inefficient, and can only reflect the seam situation of the board
However, the rail inspection vehicle is expensive, and can only detect the arching of the track slab during the train empty window period, and cannot perform real-time status monitoring

Abstract

The present invention proposes a distributed monitoring method and system for arching on track slabs. Through the synergistic effect of inclination sensors, microcontrollers and converging nodes, real-time detection of arch angles on track slabs is performed, and data processing is performed on the arching angles. The angle value detected when the train passes is filtered, so as to retain the angle value measured when the track slab is static, and convert the camber angle value of the track slab into the height of the camber for output. The output camber height can be compared with the maximum camber allowed by the track slab The height is compared to see if it exceeds the limit, and then it is further judged whether an alarm is required. The control process of the present invention adopts the mode of real-time monitoring to detect the change of the arch angle on the track plate and improve the detection efficiency.

Description

technical field [0001] The invention relates to the field of arch detection on track slabs, in particular to a distributed monitoring method and system for arches on track slabs. Background technique [0002] CRTS Ⅱ type slab ballastless track structure is one of the main track structure types adopted by my country's high-speed railway (passenger dedicated line), and has been applied in Beijing-Tianjin, Beijing-Shanghai, Beijing-Shiwu, Shanghai-Hangzhou, Hangzhou-Ningbo, Hebeng, Jinqin, Hangchang In other high-speed railways (passenger dedicated lines), the total application mileage has exceeded 5,000 kilometers on both lines. At present, the CRTSⅡ type slab ballastless track structure suitable for my country's road conditions is mainly composed of 60kg / m steel rails, elastic fasteners, prefabricated track slabs, cement emulsified asphalt mortar filling layer (abbreviated as mortar filling layer) and concrete base plate or supporting layer and other components. composition. ...
