Along with the development of high-speed railways, seamless rails are widely used, the speed of a train is improved due to the use of the seamless rails, the running is stable and reliable, and the service lives of line equipment and the train are greatly prolonged. A seamless rail is a 25m long rail welded to a 1000m to 2000m long rail. The laying line becomes a seamless line. However, as the rail gap disappears, the welded rails do not expand and contract freely when the temperature of the welded rails changes, and temperature stress is generated in the rails. Because the rail is affected by thermal expansion and contraction, when the outside air temperature is higher, the temperature of the rail can be continuously increased, and compressive stress can be formed in the rail, so that the rail expansion phenomenon between the rails is extremely easy to form; when the outside air temperature is low, the steel rail is broken due to the tensile stress formed in the steel rail. The breaking and expanding of the steel rail seriously threatens the running safety of the train. Therefore, the railway service department must know the temperature stress of the steel rail in real time, and forecast the possibility of rail expansion or rail breakage, so as to take measures to eliminate accident hidden trouble and ensure the operation efficiency, operation safety and operation reliability of the high-speed railway system.
When the existing temperature stress monitoring device for the seamless steel rail monitors the temperature stress of the seamless steel rail, manual timing measurement is mainly adopted, a measurer needs to pass a long distance to reach a measured point, and meanwhile, the temperature stress must be reached and measured at the passing clearance time of a train. In high-temperature seasons, the measurement is carried out for a plurality of times a day, so that the labor intensity is high, the measurement accuracy is low, and the safety of measurement personnel cannot be ensured.
