Train control apparatus and train control method

A train control apparatus that controls operation of a train, the apparatus comprising:

• setting reception circuitry to receive setting information regarding a temporary speed limit section where a speed of the train is temporarily limited, a speed limit in the temporary speed limit section, and a protection section where entry of the train is prohibited;
• control circuitry to generate temporary speed limit information and protection information for each train with respect to trains that travel within a control range on a basis of the setting information;
• and
• communication circuitry to transmit the temporary speed limit information and the protection information to each train, wherein
• in a case where it is not possible to include information regarding all temporary speed limit sections in the temporary speed limit information,
• the control circuitry generates protection information including information regarding a specified number of protection sections, or protection sections and temporary speed limit sections where speed limits are regarded as zero, the sections being located on a traveling direction side from a position of the train, among one or more protection sections and one or more temporary speed limit sections not included in the temporary speed limit information.

A train control method in a train control apparatus that controls operation of a train, the method comprising:

• by setting reception circuitry, receiving setting information regarding a temporary speed limit section where a speed of the train is temporarily limited and a speed limit in the temporary speed limit section;
• by control circuitry, generating temporary speed limit information for each train with respect to trains that travel within a control range on a basis of the setting information acquired from the setting reception unit;
• and
• by communication circuitry, transmitting the temporary speed limit information to each train, wherein
• in a case where it is not possible to include information regarding all temporary speed limit sections in the temporary speed limit information,
• when generating the temporary speed limit information, the control circuitry includes, in the temporary speed limit information, information regarding a specified number of temporary speed limit sections located on a traveling direction side from a position of the train, and changes a speed limit in one or more temporary speed limit sections included in the temporary speed limit information on a basis of a speed limit set in a temporary speed limit section that is adjacent to a temporary speed limit section included in the temporary speed limit information, and is not included in the temporary speed limit information.
