Problems solved by technology

However, the working environment of the rail is complex. The mounting and packaging of the sensor directly determine the accuracy of the data collected by the sensor, and the sensor will fall off during long-term operation, which will bring hidden dangers to the structural health monitoring of the rail.

Abstract

The invention discloses an embedded intelligent rail and a preparation method of the embedded intelligent rail. The intelligent rail designed and prepared is integrated with a strain and temperature sensor array, the strain and temperature sensor array is used for collecting structural state information of the rail under the operation of the train, especially in the bad environment section, concrete data is recorded to provide support for a structural health state of the early-warning track, the wheel-rail vibration situation is detected in the running of the train, and technical guarantee forthe safety monitoring of the train and the rail is provided. The invention further provides a processing and preparation method of the embedded intelligent rail. The embedded intelligent rail adoptsthe processing technology of combining laser and micro-electro-mechanics, the embedded intelligent rail which is consistent with the appearance of a traditional rail and has the same mechanical strength is obtained, the structural health information of the rail in real time is recorded, the seamless integration between a sensor and the rail is realized, the application range of the embedded intelligent rail is expanded, and the intelligent development of the rail transit industry is accelerated.

Description

technical field [0001] The invention relates to the field of rail transit and intelligent manufacturing, in particular to an embedded intelligent rail and a preparation method thereof. Background technique [0002] Railway rails have become an important choice for people to travel, and railway safety issues are becoming more and more important. The structural health of the rails has a great impact on the safety of trains. A large number of rails in the railway line have been in service under dynamic heavy loads for a long time, and are prone to corrosion, deformation, wear, cracks or even breakage. At present, the structural health monitoring of railway tracks mainly places sensors on the bottom or side of the railway track (CN201210502451.6) to realize the state monitoring of the railway track itself. Place them on rails, and conduct online monitoring and inference of rail information. However, the working environment of the railway track is complex. The mounting and inte...
