System for power facility navigation
First Claim
1. A system for power facility navigation, comprising:
- a processor configured to find a destination location and search for a path;
a mobile GIS engine connected to the processor and configured to perform data processing;
a spatial database connected to the mobile GIS engine and configured to store basic maps and power facility maps;
a non-spatial database connected to the mobile GIS engine and configured to store property information of power facilities and sections; and
a road network database connected to the mobile GIS engine and configured to store information on roads as a road network,wherein the processor comprises;
a destination setting module configured to find the destination location with a plurality of destination setting items having respective preset priorities assigned thereto, such that the destination setting items are compared with GIS data in order of the preset priorities until a match is found,a path finding module configured to search the road network database for a path leading to the destination location,a GPS coordinate processing module configured to receive location coordinates through a GPS receiver and perform coordinate conversion between different coordinate systems, anda map matching module configured to perform GPS coordinate correction.

Abstract
A system for power facility navigation is disclosed. For rapid dispatch in the field service including power failure recovery and maintenance, the destination location can be set using various items such as pole numbers, computerization codes, customer names, trade names, equipment numbers and GIS coordinates. Destination location setting and path finding can be performed in order of priorities assigned to these items and in consideration of characteristics of field service activities. Location coordinates are received through a GPS receiver, coordinate conversion is performed according to a facility GIS coordinate system, and map matching is processed when GPS coordinates do not match facility GIS coordinates. The road network database is composed of linear array structures and the structure of a link is configured to include information regarding all other links connected to the start node and end node in a manner that link information and node attributes are integrated together.
