The invention discloses a ballastless track board target and a method using the ballastless track board target to calibrate an infrared temperature measuring system. The ballastless track board targetcomprises a ballastless track board, a temperature control device, film thermocouples, a control panel and a PID controller and is characterized in that the ballastless track board and the temperature control device fixedly attach to each other, the film thermocouples are arranged in the narrow layer of the ballastless track board, the PID controller is arranged in the control panel, the temperature control device, the control panel and the film thermocouples are connected with the PID controller, and the temperature control device is connected with the control panel. A ballastless track board is mainly prepared by a ballastless track board material, the ballastless track board of the ballastless track board target is also made of the ballastless track board material, and accordingly theballastless track board target can accurately reflect the emissivity of the ballastless track board. The method can increase the calibration precision of the infrared temperature measuring system andcan measure the temperature of the ballastless track board in a high-precision manner.
Description
technical field [0001] The invention relates to the technical field of railway engineering, in particular to a ballastless track slab target and a calibration method for an infrared temperature measurement system. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The stability of the railway track structure directly affects the safety of the railway. As the main railway track structure, the ballastless track slab will cause uneven temperature distribution due to the influence of atmospheric temperature, solar radiation, precipitation and other environmental factors in the external environment. The large temperature stress will cause the deformation of the ballastless track slab structure and seriously endanger the operation safety of the train. Therefore, it is necessary to me...
