Abstract

The invention discloses a vehicle dynamic measuring device of a steel rail abrasion integrated parameter, and the vehicle dynamic measuring device comprises a visual sensor, a computer and a mileometer, wherein, a high speed image acquisition card and a measuring module are installed in the computer, the visual sensor comprises a steel rail section image system and an optical grating projector, the optical grating projector can project out more than one light planes vertical to a measured steel rail, the measuring module is used for obtaining the vertical abrasion of the steel rail, the lateral surface abrasion, the wave depth and the wave length of the wave abrasion; the invention also discloses a vehicle dynamic measuring method of a steel rail abrasion integrated parameter. The adoption of the device and the method described in the invention can improve a sampling intensity under the condition of not improving the performance of the image sensing and an acquisition hardware equipment, thereby meeting the high speed online dynamic measurement requirement of the wave abrasion, and obtaining the exact wave depth and the wave length of the wave abrasion.

Description

Technical field [0001] The invention relates to dynamic measurement technology, in particular to a vehicle-mounted dynamic measurement device and method for comprehensive parameters of rail wear. Background technique [0002] Regular track inspection is very important for reasonable planning and low-cost maintenance of railway transportation: On the one hand, in the early stage of track wear and deformation, track inspection helps to formulate a reasonable railway maintenance schedule to avoid dangerous situations; On the other hand, effective track inspection will lay the foundation for the transition from periodic repair to state repair, so that limited manpower and equipment resources can be better utilized, and track maintenance costs can be effectively saved. [0003] At present, many research institutions and scholars at home and abroad have conducted research on the detection methods of rail wear and have successfully developed various measuring devices. According to the d...
