[0004] In general, a blasting system, which blasts and demolishes a target object by using an explosive, is used in the field of construction where blasting of bedrock, blasting of abandoned buildings, blasting in open-pit mines, and the like are conducted.

[0005] Specifically, an area or target object, which is to be blasted, is divided into a plurality of sections, and a plurality of blast holes into which explosives are inserted is drilled for each section. After the explosives are inserted into the respective drilled blast holes, the blast holes are connected to a blasting device. By detonating detonators positioned in the respective blast holes, the explosives are exploded and the blast target object is blasted and demolished.

[0006] In such a blasting site, on-site safety management through tracking the locations or routes of workers, visitors, and others at the blasting site and tracking movement of work vehicles is essential, and thus a technology capable of checking work situations in real time is required.
