Abstract

The invention discloses a track comprehensive detection and diagnosis method. The method comprises the following steps: (S11) a front-end sensing assembly carries out excitation of original sensing signals of all channels and acquisition of feedback signals; (S12) a damage detection signal processing assembly performs acquisition and parallel processing of feedback signals of sensors of all channels, and performs real-time management, control and target result data processing on the feedback signals of the sensors of all the channels; and (S13) an intelligent identification processing computercarries out intelligent identification processing on the data output by the damage detection signal processing assembly to complete calculation, processing and dynamic output of final damage data. The technical problem that an existing steel rail damage detection mode is single in detection means and low in intelligent degree, and comprehensive damage detection and comprehensive health state diagnosis of a railway steel rail cannot be achieved can be solved.

Description

technical field [0001] The invention relates to the technical field of track engineering machinery, in particular to a comprehensive track detection and diagnosis method applied to non-destructive testing of railway tracks. Background technique [0002] At present, with the vigorous development of railway transportation, the mileage of railway construction in my country is increasing day by day. High-density, high-speed and heavy-duty railway traffic have gradually become the main characteristics of modern railways. The structural performance and health of railway rails are crucial to ensuring railway transportation. safety is of paramount importance. During the long-term high-speed and high-density running of trains, railway rails are prone to various fatigue cracks and wear. These early damages will continue to develop over time. After a certain period of time, they can develop into Serious injury, resulting in rail breakage, resulting in destructive safety accidents. The...
