Background
The ballastless track is a track structure which adopts concrete, asphalt mixture and the like to replace a granular broken stone track bed, and the ballastless track is widely applied to the construction of high-speed railways in China as the most main structural form. Compared with a ballast track, the ballastless track avoids the problem of ballast splashing, and has the advantages of good smoothness, good stability, long service life and less maintenance work.
Because the ballastless track is directly exposed to the natural environment, meteorological factors have great influence on the temperature change of the surface and the interior of the ballastless track. For example, during continuous high temperature in summer, damage such as breakage or upwarp of a track slab occurs at a wide and narrow joint of a ballastless track due to temperature stress accumulation; in the low-temperature period in winter, the diseases such as cracking of the surface layer of the ballastless track, exposure of aggregate, corrosion and the like are caused by repeated freezing and thawing action. Because the breadth of China is vast, the climate difference between south and north is large, and the running safety of trains is seriously influenced by track structure diseases caused by meteorological factors. Therefore, in order to ensure the safety of railway operation and prolong the service life of the railway, the rails need to be maintained. At present, maintenance work is mainly carried out corresponding adjustment on an unsmooth track structure through manual interference so as to reduce track abnormal deformation caused by expansion with heat and contraction with cold. However, the manual maintenance effect is not controllable, and the real-time performance of maintenance is also not good.

The light shielding layer can prevent light from entering the region covered by the cover body 100 and conduct heat, so that the light is shielded to prevent the temperature in the cover body 100 from rising too fast, and heat can be conducted at the same time.
The track temperature control system further comprises a dehumidification module, the dehumidification module comprises a humidity measurer and a dehumidifier, and the humidity measurer and the dehumidifier are respectively in communication connection with the control terminal 400.

It will be appreciated that because the train transit time is relatively short, the effect of temperature changes on the track 500 during the time period in which the enclosure 100 is opened is negligible.
The control terminal 400 further includes a storage module, and the storage module is connected to the data acquisition module and the data analysis module respectively. The storage module stores a temperature threshold value for the data analysis module to compare and judge the obtained temperature data with the temperature threshold value.

The control terminal 400 detects the temperature inside the cover 100 according to the signal sent by the detection device 200, and analyzes and compares the temperature to determine whether the temperature increasing module 330 needs to be started at the same time.
Referring to fig. 4, fig. 4 shows a state of the rail temperature control system in a high temperature environment. In order to maintain the ambient temperature inside the enclosure 100 in a high temperature environment, the control terminal 400 detects the temperature inside the enclosure 100 according to the signal transmitted by the detection device 200 and performs an analysis and comparison to determine whether the reflective insulation module 310 and/or the light shielding module 340 need to be turned on. If the temperature continues to rise, the control terminal 400 detects the temperature in the cover body 100 through a signal sent by the detection device 200, and controls the cooling module 320 to be started after analyzing and comparing the temperature, or controls the cover body 100 to be started to accelerate heat dissipation. In the process of adjusting the temperature by the track temperature control system, the starting sequence of the modules is not limited to the above-mentioned mode, and one or more of the reflective insulation module 310, the light shielding module 340 and the cooling module may be started.

The control terminal 400 may control the heating module 330 to be turned on according to the signal sent by the detection device 200 to maintain the ambient temperature inside the cover 100, or simultaneously turn on the ice and snow melting module, etc.
Referring to fig. 6, fig. 6 illustrates an opened state of the cover 100 when both side trains pass through the track temperature regulating system at the same time.
