Geospatial Information Service System using DCU in communication network for smartgrid and method using the same

摘要

The present invention relates to a geospatial information service system using a dcu of a smart grid communication network and a geospatial information service method using the same. The system includes: a smart grid communication network including power lines for transmitting power and communication signals; a plurality of DCUs installed in plurality, distributed over separate locations in middle stages of the power lines, collecting customer AMR data, and including wireless modems for wireless communication with a mobile communication terminal located within a certain range; and a geospatial information service device connected to the smart grid communication network, grasping real time location information of the mobile communication terminal on the basis of communication distances between the plurality of DCUs and the mobile communication device, and providing a spatial information service based on the location information to the mobile communication terminal. According to the present invention, for implementing an infra for providing the geospatial information service, DCUs on electric poles configuring the smart grid communication network are used without using the conventional cellular communication network or GPS. Accordingly, an economic loss can be prevented which is cased by duplicated investment for communication network facility construction, and cost can be reduced.
