METHOD FOR REMOVING A SHADOW ZONE ON GUIDING THE POSITION OF TRAIN AND TRAIN TRAFFIC INFORMATION SYSTEM

摘要

The present invention relates to a method for removing a shadow zone on a guiding position of a train and a train traffic information system capable of confirming and outputting an accurate position regardless of a communication condition of a train by solving a problem which can not accurately track the current position when a train enters into a section having a bad communication condition. The method comprises a GPS coordinate confirmation step of enabling a train position guide system to check the possibility of GPS coordinate confirmation; a first position confirmation step for enabling the train position guide system to confirm a GPS coordinate for the current position when the possibility of the GPS coordinate confirmation is confirmed in the GPS coordinate confirmation step; a distance calculation step for calculating the moving distance of the train by receiving a rotation speed from a taco-meter in which the train position guide system measures the rotation speed of a driving shaft in the train when the impossibility of the GPS coordinate confirmation is confirmed in the GPS coordinate confirmation step; a second position confirmation step for enabling the train position guide system to confirm a point which is separated from a finally confirmed GPS coordinate point with the moving distance; and an information output step for enabling the train position guide system to display a train icon by confirming a confirmation point in the second confirmation step or a point corresponding to the GPS coordinate confirmed in the first position confirmation step on the map image.
