IN-VEHICLE GUIDANCE DISPLAY SYSTEM AND IN-VEHICLE GUIDANCE DISPLAY METHOD
First Claim
1. An in-vehicle guidance display system comprising:
- a ground system that creates guidance display data to be used to display a guidance in a vehicle of a train; and
an on-board system that is mounted on the train and displays a guidance using guidance display data created by the ground system, whereinthe ground system includesa guidance-display-data creation device that creates, for each line as the guidance display data, a dataset including information on a stop station pattern for each train type, effective-period related information indicating at least one of a start date and time and an end date and time of an effective period, and train number information, anda data distribution server that holds the guidance display data and that wirelessly distributes all or a part of the dataset included in the held guidance display data to the on-board system at a predetermined timing, andthe on-board system includesa central distribution server that manages the dataset distributed from the ground system, and when a train number of a train in which the on-board system is installed is set,distributes the dataset to each vehicle if the central distribution server holds a dataset corresponding to the train number and within the effective period, andnotifies the data distribution server of the train number to acquire a corresponding dataset and distributes the corresponding dataset to each vehicle if the central distribution server does not hold the dataset corresponding to the train number and within the effective period, anda display terminal device that is installed in each vehicle and that displays a guidance on a display device in the vehicle based on the dataset distributed from the central distribution server.

Abstract
A ground system includes a guidance-display-data creation device that creates a dataset including information on a stop station pattern, effective-period related information, and train number information as guidance display data, and an information distribution server that wirelessly distributes all or a part of a dataset included in the guidance display data to an on-board system. The on-board system includes a central distribution server that manages the distributed dataset, and when a train number is set, distributes the dataset to each vehicle if the central distribution server holds a dataset corresponding to the train number and within an effective period, and notifies the information distribution server of the train number to acquire a corresponding dataset and distributes the corresponding dataset to each vehicle if the central distribution server does not hold the dataset corresponding to the train number and within the effective period.

10. An in-vehicle guidance display method executed by a railway system including a ground system that creates guidance display data to be used to display a guidance in a vehicle of a train, and an on-board system that is mounted on the train and displays a guidance using guidance display data created by the ground system, the in-vehicle guidance display method comprising:
-
a guidance-display-data creating step of, by the ground system, creating, for each line as the guidance display data, a dataset including information on a stop station pattern for each train type, effective-period related information indicating at least one of a start date and time and an end date and time of an effective period, and train number information; a data distributing step of, by the ground system, wirelessly distributing all or a part of the dataset included in the guidance display data to the on-board system at a predetermined timing; and a guidance displaying step of, by the on-board system, managing the dataset distributed from the ground system, and when the train number of the train in which the on-board system is installed is set, distributing the dataset to each vehicle and displaying a guidance on a display device in each vehicle if a dataset corresponding to the train number and within the effective period is held, and notifying the ground system of the train number to acquire a corresponding dataset, distributing the acquired dataset to each vehicle, and displaying the guidance on the display device in each vehicle if the dataset corresponding to the train number and within the effective period is not held.
