NOVELTY - The floor plate has a wireless power transmission radio wave reception rectification multiple power matching power supply output device that is provided with temperature sensing start switch with rectenna in an operation indicator that operates in the snow melting temperature range of 50° C. A heat-generating structure is made of nets assembled from graphene or carbon nanotube yarns that have physical properties suitable for a place of use, weather, and conditions of use. USE - Heating floor plate for performing snow coverage avoidance snow melting and freezing prevention heat insulation. ADVANTAGE - The tool and equipment are used for snow avoidance snow-melting and freeze-prevention heat retention with proper efficiency.
