[0028] In the embodiment, the rail temperature support 6 is attached to the surface of the shell 401, a through hole 601 is formed on the rail temperature support 6, and a bolt is arranged in the through hole 601. A bolt head is connected to a first end of the bolt.

By using the bolt connection between the rail temperature support 6 and the line structured light scanning sensor 4, it is convenient to install and replace the rail temperature support 6 on the surface of the line structured light scanning sensor 4.
[0029] In one embodiment, a connecting hook is arranged on the line structured light scanning sensor, and a connecting hole is formed on the surface of the rail temperature support, and the connecting hook is arranged in the connecting hole.
[0030] In the embodiment, a plurality of connecting holes are formed on the surface of the rail temperature support, and the plurality of connecting holes are located in the same plane. A plurality of connecting hooks are arranged on the surface of the line structured light scanning sensor. When the rail temperature support is installed on the surface of the line structured light scanning sensor, the position of the rail temperature support is adjusted, the connecting hooks are respectively arranged through the corresponding connecting holes, and the rail temperature support is hung on the surface of the shell 401.
[0031] As shown in FIG. 6, Figure 1 In one embodiment, a mounting hole 602 is arranged on the rail temperature support 6, and the rail temperature sensor 7 is arranged in the mounting hole 602.
[0032] In the embodiment, the mounting hole 602 is formed on the rail temperature support 6, and an axis of the mounting hole 602 is perpendicular to an axis of the through hole 601.

[0033] As shown in FIG. 6, Figure 1 In one embodiment, the electric heating sheet 5 is further arranged on the surface of the line structured light scanning sensor 4.
[0034] In the embodiment, the electric heating sheet 5 is attached to the outer surface of the shell 401 of the line structured light scanning sensor 4. Specifically, the electric heating sheet 5 is arranged on the surface of the shell 401, and an electric energy input end of the electric heating sheet 5 is connected to the power supply 9.

[0037] As shown in FIG. 9, in one embodiment, the monitoring end of the controller 10 is electrically connected to the temperature control switch 8. Figure 2
[0038] In this embodiment, the monitoring end of the controller 10 is electrically connected to the first end of the temperature control switch 8 through a data line, so that the controller 10 detects whether there is current flowing between the electric heating sheet 5 and the power supply 9 through the data line. When there is current flowing between the temperature control switch 8 and the power supply 9, the controller 10 identifies that the temperature control switch 8 is in a closed state, so that the electric heating sheet 5 is in a working state. When there is no current flowing between the temperature control switch 8 and the power supply 9, the controller 10 identifies that the temperature control switch 8 is in an open state, so that the electric heating sheet 5 is in a non-working state. Thus, the controller 10 monitors the state of the temperature control switch 8 to know whether the heating system is in an activated state, which is helpful for the overall monitoring and management of the system. In addition, the controller 10 can also record the action history of the temperature control switch 8, including the switch time and frequency, which is helpful for the maintenance and performance analysis of the equipment.
[0039] In one embodiment, the temperature control switch 8 is a mechanical switch.
[0040] In this embodiment, the mechanical temperature control switch realizes the control function based on physical changes. The mechanical temperature control switch contains a temperature sensing element, such as a bimetallic strip or a liquid expansion element. When the ambient temperature rises or falls to a certain threshold value, the temperature sensing element will physically deform or expand, triggering a mechanical action to push the closing or opening of the switch contacts. Using a mechanical temperature control switch has the effects of simplicity, high reliability, no need for power supply and low cost.
[0041] As shown in FIG. 10, in one embodiment, the temperature control switch 8 is a solid state switch. Figure 2 As shown in the figure, in one embodiment, the output end of the controller 10 is connected with a male plug 11, the input end of the track temperature sensor 7 and the input end of the temperature control switch 8 are connected with a female plug 12, and the male plug 11 is plugged with the female plug 12.
[0042] In this embodiment, the first output end, the second output end and the monitoring end of the controller 10 are connected with the male plug 11 through data lines, and the power output end of the power supply 9 is connected with the controller 10 through electric wires on the same male plug 11. The female plug 12 is plugged with the male plug 11, and the female plug 12 is connected with the line structured light scanning sensor 4, the track temperature sensor 7 and the temperature control switch 8 through power lines and data lines respectively. Specifically, the female plug 12 is connected with the power input end of the line structured light scanning sensor 4, the power input end of the track temperature sensor 7 and the first end of the temperature control switch 8 through power lines. The female plug 12 is connected with the control end of the line structured light scanning sensor 4, the control end of the track temperature sensor 7 and the first end of the temperature control switch 8 through data lines. The monitoring end of the controller 10 is connected with the first end of the temperature control switch 8 through the data line of the female plug 12. The connection between the controller 10, the line structured light scanning sensor 4, the track temperature sensor 7 and the temperature control switch 8 through the unified standard male plug 11 and the female plug 12 can improve the compatibility of the equipment, so that the equipment or components of different manufacturers can be connected with each other. And each component can be quickly and conveniently connected and disconnected, which is convenient for the assembly and maintenance of the equipment.
[0043] As shown in the figure, in one embodiment, the controller 10 is connected with the line structured light scanning sensor 4, the track temperature sensor 7 and the temperature control switch 8 through the male plug 11 and the female plug 12. Figure 3 As shown in the figure, in one embodiment, the controller 10 is connected with the line structured light scanning sensor 4, the track temperature sensor 7 and the temperature control switch 8 through the male plug 11 and the female plug 12.
[0044] In this embodiment, the surface of the cover 1 is provided with an upper opening, and the support plate 2 is connected with the upper opening edge of the cover 1. The surface of the support plate 2 is provided with a connecting threaded hole, and a connecting bolt is arranged in the connecting threaded hole. The upper opening edge of the cover 1 is provided with an auxiliary threaded hole. The connecting bolt is sequentially arranged in the connecting threaded hole and the auxiliary threaded hole, and the connecting bolt is threadedly connected with the side wall of the auxiliary threaded hole. The inside of the cover 1 is provided with a mounting cavity. When the support plate 2 is buckled with the upper opening of the cover 1, the line structured light scanning sensor 4 is placed in the inside of the cover 1, and the line structured light scanning sensor 4 and the track temperature sensor 7 are protected by the cover 1. Moreover, the surface of the cover 1 is provided with a collection window 101 for the line structured light scanning sensor 4 and the track temperature sensor 7 to collect the steel rail, so that the line structured light scanning sensor 4 and the track temperature sensor 7 can normally work in the inside of the cover 1.
[0045] As shown in the drawings, Figure 3 In one embodiment, a light-transmitting plate 102 is arranged in the collection window 101, and the edge of the light-transmitting plate 102 is connected with the edge of the collection window 101.

The edge of the light-transmitting plate 102 is connected with the edge of the collection window 101 through a sealing strip, thereby improving the waterproof effect between the light-transmitting plate 102 and the shell 1.
[0047] In one embodiment, the material of the light-transmitting plate 102 is glass.
[0048] In this embodiment, glass is used as the light-transmitting plate 102, and the high light refraction rate of glass enables the line structured light scanning sensor 4 and the rail temperature sensor 7 to more clearly obtain the image or video of the rail surface.
[0049] In one embodiment, the material of the light-transmitting plate 102 is plastic.
[0050] In this embodiment, the polycarbonate or acrylic in the plastic needs to have good light transmission to ensure that the sensor can receive sufficient light for measurement. In addition, the plastic material is easy to process and can be designed into different shapes and sizes as needed. At the same time, the weight of the plastic is relatively light, which helps to reduce the weight of the overall device. Therefore, plastic meets the requirements for making the light-transmitting plate 102.
[0051] As shown in the drawings, Figure 3 In one embodiment, a wiring box 3 is further included, and the wiring box 3 is connected with the edge of the shell 1.
[0052] In this embodiment, the wiring box 3 is connected with the surface of the shell 1 through a sealing ring, so that the wiring box 3 and the shell 1 are sealingly connected, thereby improving the sealing property between the wiring box 3 and the shell 1. The wiring box 3 can protect the internal wiring from the influence of the external environment, such as preventing the invasion of moisture, dust and other pollutants, thereby prolonging the service life of the wiring. The design of the wiring box 3 helps to arrange and fix the cables, so that the wiring is more orderly, and the installation and maintenance are facilitated.
