In-vehicle information distribution system and in-vehicle information distribution method

摘要

An in-vehicle information distribution device includes a current-status-information acquisition unit that acquires current-status information, a status-type determination unit that refers to a status-type list table, and determines to which of status types classified in the status-type list table the current-status information corresponds, a status determination unit that refers to a status-type/status-determination-information correspondence table, acquires status-determination information corresponding to the determined status type, and determines a status of a train based on the status-determination information, and a display-content decision unit that refers to a status-type/display-content-information correspondence table, which classifies a display content to be displayed on a display device (AC-drive) and a display device (DC-drive) into status types, acquires display-content information corresponding to the determined status type, and selects display data corresponding to the display-content information.

1. An in-vehicle information distribution system comprising:
an electric-power storage device that is installed in a train and outputs DC power by using electric power from an overhead wire as a supply source; a first display device in a vehicle, where the first display device operates by being supplied with AC power obtained by converting electric power from the overhead wire; a second display device in a vehicle, where the second display device operates by using the electric-power storage device as a power source; a train-information management device that operates by using the electric-power storage device as a power source and manages train information including state information on a vehicle-mounted device; and an in-vehicle information distribution device that operates by using the electric-power storage device as a power source and selects display data for an in-vehicle guide to be displayed on the first and second display devices, wherein the in-vehicle information distribution device includes
a current-status-information acquisition unit that acquires a plurality of kinds of train information from the train-information management device and acquires state information from each of the first and second display devices, as a group of current-status information,a status-type determination unit that refers to a status-type list table, which classifies a status of the train into a plurality of kinds of status types including at least whether the train is in a normal state according to content of the group of current-status information, and that determines to which of status types classified in the status-type list table the group of current-status information acquired by the current-status-information acquisition unit corresponds,a status determination unit that refers to a status-type/status-determination-information correspondence table, which classifies status-determination information used for determining a status of the train into the status types, that acquires status-determination information corresponding to a status type determined by the status-type determination unit, and that determines a status of the train based on the status-determination information, anda display-content decision unit that refers to a status-type/display-content-information correspondence table, which classifies a display content to be displayed on the first and second display devices into the status types, that acquires display-content information corresponding to a status type determined by the status-type determination unit, and that selects display data corresponding to the display-content information.
