Abstract

The invention discloses a method and device for measuring longitudinal displacement of a steel rail. The method comprises: a measurement instruction sent by the upper computer is received; according to the measurement instruction, a laser transmitter is controlled to emit laser to a positioning gauge fixed at a steel rail; an image sensor is controlled to collect a first image of the positioning gauge, wherein the first image includes a laser beam; and according to the first image fed back by the image sensor, longitudinal displacement of the steel rail is generated. Therefore, a technical problem of low detected data precision caused by the poor anti-vibration performance of the apparatus for detecting the displacement of the steel rail according to the correlated technique is solved.

Description

Technical field [0001] The invention relates to the railway field, and in particular to a method and device for measuring the longitudinal displacement of a steel rail. Background technique [0002] When laying a new seamless railway, it is necessary to lock the rail only when the track is stretched uniformly and the track temperature meets the locked rail temperature range. In order to monitor whether the track is stretched evenly at any time, it is often necessary to set the track at 1000 or 1500 meters. Monitor the stretching of each point of the track within the scope. [0003] In the prior art, magnetic ruler detection technology and rope distance measurement technology are often used to measure the displacement of the steel rail. In the magnetic ruler detection technology, a magnetic displacement reading device is used to obtain the rail displacement data. In the technology, one end of the rope displacement sensor is fixed on the rail, and one section is fixed on the track p...
