a generator for supplying power so that the battery can be charged;
The battery, when the generator fails, a spare battery capable of supplying power to the vehicle; Fusion-type road marking machine, characterized in that it may be further provided. 4. The method of claim 3,
It further includes; a paint supply unit provided adjacent to the power supply unit, in which paint is prepared;
The paint supply unit,
a paint container provided in the central part of the vehicle, the paint container being accommodated therein;
a reflective material container provided adjacent to the paint storage unit and accommodating a reflective material therein; and
a melting furnace provided in the center of the vehicle, in which the paint is dissolved;
The paint container and the reflector container are mounted on the vehicle, so that the paint and the reflector can be constantly replenished with the melting furnace while moving or painting. 5. The method of claim 4,
The melting furnace,
a furnace vessel in which the paint and the reflective material are accommodated therein;
a melting furnace cover provided at the upper end of the melting furnace container and partially opening and closing so as to inject paint and a reflective material therein;
a stirrer that is provided inside the melting furnace vessel in a state penetrating the melting furnace cover, and can mix the contents;
a melting furnace discharge port formed at the lower end of the melting furnace vessel so that the molten paint can be discharged; and
A fusion-type road marking machine comprising a; flat burner for applying heat to the melting furnace vessel. Using the fusion-type road marking machine of claim 1,
an automatic painting setting step of inputting road information and image data by a driver through the manipulation input unit;
a data processing step of receiving the information from the manipulation input unit from the control unit and mapping the information to an image of a road sign;
a motion control step in which the controller controls the operation of the vehicle and the painting unit to paint road markings on the road; and
A control method of a fusion-type road marking machine comprising a; a painting inspection step in which the sensor senses the quality of the road marking painted on the road.
