METHOD AND SYSTEM FOR UPDATING TRAIN CONTROL DATA USING BROADBAND WIRELESS ACCESS SYSTEM
First Claim
1. A system for updating train control data comprising:
- a ground control unit that is installed on the ground and includes a ground function controller configured to generate train control data and a ground wireless communication unit configured to give identification information identifying train control data and transmit the train control data including the identification information to an on-board device via a wireless network; and
an on-board device that is installed in a train and includes an on-board wireless communication unit configured to receive the train control data and check the identification information included in the train control data and an on-board function controller configured to update the train control data under control of the on-board wireless communication unit.

Abstract
A system and method for updating train control data are provided. The system for updating train control data can operate to revise, update and maintain the corresponding train control functions installed in an on-board device without workers directly approaching on-board and ground devices using a broadband wireless access system. The on-board device is configured to receive train control data classified by identification information via a wireless network and determine whether the train control data is train control data to be updated using the identification information. The on-board device is configured to update the train control data depending on whether the train control data is the train control data to be updated.

8. A method of updating train control data comprising:
-
receiving, at an on-board device, train control data classified by identification information from a ground control unit via a wireless network; determining, at the on-board device, whether the train control data is train control data to be updated using the identification information; and updating the train control data at the on-board device, depending on whether the train control data is the train control data to be updated. - View Dependent Claims (9, 10, 11)
