And manual acquisition is not needed, so that the cost is saved, and the safety of operators is guaranteed. The snow melting efficiency is improved. The display module is arranged to display the temperature inside and outside the box of each wireless turnout snow melting control box and the current of the snow melting branch, so that an operator can clearly and visually know the running state of the snow melting control equipment. Through setting up alarm module, when exceeding the analysis result of each preset threshold value in the analysis result of the box internal temperature of wireless switch snow melt control box, box external temperature and the electric current of snow melt branch road, can report to the police. Therefore, the operation personnel can be reminded in time so that the operation personnel can correct the operation personnel in time.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
