Embodiment Construction

[0038] Hereinafter, an embodiment of the present invention will be described based on the drawings. In addition, the structure which attaches|subjects the same code|symbol in each drawing represents the same structure, and the description is abbreviate|omitted suitably. In this specification, when referring to collectively, it is indicated by a reference sign with an abbreviated suffix, and when indicating an individual structure, it is indicated by a reference sign with an suffix.

[0039] The present invention proposes a distributed monitoring system for arches on track slabs, such as figure 1 As shown, the system includes: an ARM microcontroller, an inclination sensor, and a converging node, and the ARM microcontroller controls the inclination sensor and the Zigbee module to start working through I / O; the inclination sensor collects a complete set of inclination data ,

[0040] The data aggregation node includes a Zigbee module, a data processing module and a wireless rou...

Abstract

The invention provides a distributed monitoring method and system for arching of a track plate. Through the synergistic effect of the inclination angle sensor, the microcontroller and the aggregationnode, the upward arching angle of the track plate is detected in real time; data processing is carried out on the upwarp angle; the angle value detected when a train passes by is filtered out, so thatthe angle value measured when the track plate is static is reserved, the upward arching angle value of the track plate is converted into the upward arching height to be output, the output upward arching height can be compared with the maximum upward arching height allowed by the track plate to judge whether the limit is exceeded or not, and then whether alarm needs to be given or not is further judged. A real-time monitoring mode is adopted in the control process, the upward arching angle change of the track plate is detected, and the detection efficiency is improved.

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. ...
