[0028] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0029] When implementing, follow these steps:

[0030] 1) The temperature sensor 408 detects that the temperature of the housing 1 is too low, and transmits the detected data to the temperature control switch 407 through an electrical signal, and the temperature control switch 407 transmits it to the wireless PLC 409;

[0031] 2) Then, after receiving the data, the wireless PLC 409 sends remote information to the user, who decides whether to heat the device or automatically according to the temperature environment;

[0032] 3) Finally, the wireless PLC 409 receives the instruction to start the operation of the heating plate 405, and diffuses the temperature to the outer surface of the shell 1 through the heat-conducting sheet 403, thereby improving the snow melting efficiency.

[0033] In summary, the snow melting device of the THDS equipment isolates the heating components and THDS equipment and other structures inside the shell 1 through the insulating shell 402 and the insulating pipe sleeve 404, so as to avoid negative interference of the temperature on the measurement and monitoring operation of the THDS equipment when the temperature rises.

[0034] Moreover, by utilizing the design of the thermally conductive sheet 403, the heat generated by the two heating sheets 405 when heated can be quickly diffused to the contact area between the thermally conductive sheet 403 and the inner wall of the shell 1, thereby accelerating the heating rate of the shell 1 and increasing the convenience in use. At the same time, the weakened groove 406 reduces the thickness of the contact area between the temperature sensor 408 and the inner wall of the shell 1, thereby improving the accuracy of temperature detection on the outer surface of the shell 1 and increasing the efficiency of the response of the wireless PLC 409 and the temperature control switch 407, further ensuring the convenience of use for users and driving safety, and solving the problem in the prior art that the probe box and the freezing protection door are prone to failure, and the axle temperature detection cannot be performed, affecting driving safety.
