Smart drilling machine, smart drilling system, and method of controlling smart drilling system

A method of controlling an external terminal having a display, the method comprising:

• a setting operation of connecting a total station fixedly positioned on a floor surface of a construction site and a drilling machine via communication and displaying perforation location information in a design space, wherein the terminal is separated from the drilling machine and the total station, and is configured to perform the setting operation via manipulation of the terminal by an operator;
• a first measurement operation of acquiring location information of a reference point of an actual space from the total station;
• a first matching operation of mapping the design space and the actual space and displaying on the display a total station icon representing a mapped position of the total station in the design space;
• a second measurement operation of acquiring location information of the drilling machine from the total station;
• a second matching operation of mapping a location of the drilling machine in the actual space and a location of the drilling machine in the design space and displaying on the display a drilling machine icon representing a mapped position of the drilling machine in the design space to identify relative positions of perforation points, the total station, and the drilling machine;
• and
• a control operation of performing perforation through a drill of the drilling machine.
