Abstract

The invention discloses a point rail with a self-detection function used for a high-speed railway turnout. The point rail comprises a compromise rail (10), at least one optical fiber (20), an optical fiber abrasion wear sensor (30) and a demodulating system (40), wherein the compromise rail (10) serves as a rail for a rail train to travel and is used for placing the optical fiber (20); the at least one optical fiber (20) is arranged on the lower part of the tip of the compromise rail (10) and is used for sensing deformation and crack situations of the compromise rail (10); the optical fiber abrasion wear sensor (30) is used for monitoring the wear abrasion situation of the compromise rail (10); and the demodulating system (40) is used for demodulating the output signals of the optical fiber (20) and the optical fiber abrasion wear sensor (30) so as to obtain the deformation and the wear abrasion. By utilizing the point rail, the problems of real-time self-detection of the deformation and the crack of the rail and the long-distance transmission of the signals are solved.

Description

technical field [0001] The invention relates to the technical field of railway traffic, in particular to a core rail with self-detection function for high-speed railway turnouts. Background technique [0002] With the continuous increase of railway traffic, the wear and tear of rails is becoming more and more serious. Rail wear can lead to increased deformation of the track or even rail breakage. All countries in the world have strict controls on the wear and deformation of rails. [0003] However, there is currently a lack of an effective method to monitor the deformation state of the rail in real time and capture the occurrence of rail cracks. Utility model patent 01224941.6 discloses a rail dynamic deformation measuring device. The technical solution is to install two supports on the rail and install a displacement sensor between the supports, and use the displacement sensor to detect the displacement between the supports. Deformation of the rail. This technical solut...
