DETAILED DESCRIPTION

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that in the embodiments of the present application, the extension direction of the rail 1 refers to the length direction of the rail 1.

[0038] As shown in Figures 1 to 3 The rail temperature monitoring device provided by the embodiments of the present application includes two mounting parts 20, a control part 50 and a plurality of temperature detection pieces 40. The two mounting parts 20 are configured to be arranged at intervals along the extension direction of the rail 1. The control part 50 is connected with the two mounting parts 20 and is located between the two mounting parts 20. The plurality of temperature detection pieces 40 are arranged at intervals along the vertical direction on the rail 1 to detect the temperature of at least two of the rail head, the rail waist and the rail bottom of the rail 1. The control part 50 is electrically connected with the plurality of temperature detection pieces 40 to process the received data.

[0039] In the above technical solution, the plurality of temperature detection pieces 40 are arranged at intervals along the vertical direction on the rail 1, and the control part 50 is mounted on the rail 1 by the mounting part 20. The plurality of temperature detection pieces 40 are electrically connected with the control part 50. In this way, the control part 50 can process the temperature detected by the plurality of temperature detection pieces 40, so as to realize real-time online monitoring of the temperature of the rail 1.

[0040] Further, the plurality of temperature detection pieces 40 are arranged at intervals along the vertical direction on the rail 1 and are electrically connected with the control part 50. In this way, the plurality of temperature detection pieces 40 can detect the temperature of a plurality of specific points on the rail 1, and then transmit the temperature detection data to the control part 50 for processing. Thus, the temperature of the rail 1 can be detected more accurately, and the accuracy of detecting the temperature of the rail 1 is improved.

[0041] A rail temperature monitoring device known to the inventor only provides a support column or support frame for mounting a rail waist temperature detection piece and a rail bottom temperature detection piece in order to avoid affecting train operation, but cannot realize temperature detection of the rail head.

[0042] Therefore, the rail temperature monitoring device provided by the embodiments of the present application can detect the temperature of the rail head and reduce the influence on the train operation. Specifically, in the embodiments of the present application, the plurality of temperature detecting members 40 include the rail bottom temperature detecting member 41, the rail waist temperature detecting member 42 and the rail head temperature detecting member 43, so that the temperature of the rail bottom and the rail waist of the rail 1 can be detected, and the temperature of the rail head of the rail 1 can be detected, thereby the temperature of the rail 1 at multiple positions in the vertical direction can be detected, and the temperature of the rail 1 can be detected more accurately.

[0043] Preferably, in the embodiments of the present application, the temperature detecting member 40 is a temperature sensor.

[0044] As shown in Figure 2 , Figure 3 and Figure 5 , in the embodiments of the present application, the mounting portion 20 includes two mounting members 22 arranged at intervals and a connecting member 21 for connecting the two mounting members 22, and each mounting member 22 is provided with a mounting groove 202 for mounting the rail bottom, and the two mounting grooves 202 are arranged oppositely.

[0045] Through the above arrangement, the rail bottoms on both sides of the rail 1 can be clamped into the two mounting grooves 202, and then the two mounting members 22 are connected by the connecting member 21, so that the mounting portion 20 can be stably mounted on the rail 1, thereby the control portion 50 can be stably mounted on the rail 1, and the temperature of the rail 1 can be monitored in real time and online.

[0046] As shown in Figures 3 to 5 , in the embodiments of the present application, the rail temperature monitoring device further includes a sleeve 5021 arranged on the control portion 50, the sleeve 5021 is located between the two mounting members 22, and the mounting member 22 is further provided with a mounting through hole 201, and the connecting member 21 is arranged in the two mounting through holes 201 and the sleeve 5021.

In this way, the average temperature of the steel rail 1 can be obtained more accurately, thereby improving the accuracy of obtaining the temperature of the steel rail 1.

[0134] As shown, in the embodiment of the present application, the third judging step includes a second calculating step of calculating the average of the rail waist temperature if the obtained temperature includes the rail waist temperature, and a third calculating step of calculating the average of the rail bottom temperature and the rail head temperature if the obtained temperature does not include the rail waist temperature. In this way, the average temperature of the steel rail 1 can be obtained more accurately, thereby improving the accuracy of obtaining the temperature of the steel rail 1. Figure 12

[0135] Specifically, in the embodiment of the present application, after the data processing step, the steel rail temperature monitoring method further includes a step of saving the processed average temperature by using a data storage module. In this way, the data security can be ensured.
