Abstract:
In a ground apparatus system, polling communication where a ground apparatus serves as a primary station and a train serves as a secondary station is performed. A ground apparatus that is a ground apparatus of the ground apparatus system and is capable of communicating with a platform screen door control apparatus performs polling communication at a first communication frequency to obtain train location information from the train. When the train reaches an impending arrival range including a stop position at a station, the ground apparatus switches the communication frequency to a second communication frequency higher than the first communication frequency. The apparatus then transmits, to the train through polling communication, synchronized opening and closing control instruction information received from the platform screen door control apparatus, and transmits, to the platform screen door control apparatus, vehicle state information obtained from the train through polling communication.

Claim (Index 1):
A ground apparatus of a ground apparatus system in which a plurality of ground apparatuses are provided along a predetermined railway route to perform radio communication with a train,\n the plurality of ground apparatuses being disposed so that radio communication control regions of adjacent ground apparatuses partially overlap each other in order to prevent occurrence of a communication blank zone of the radio communication, the ground apparatus being configured to be capable of communicating with a platform screen door control device for a platform screen door installed at a station where the train stops, the radio communication being polling communication in which the ground apparatus serves as a primary station, and the train serves as a secondary station, the train being configured to reply with reply information including train location information, and vehicle state information to be used in cases where the platform screen door is opened and closed in synchronization with a vehicle door, when polling from the ground apparatus is received, the reply information serving as a reply to the polling, the ground apparatus, comprising: a radio communication control unit that performs the polling communication at a given communication frequency, and obtains the reply information from the train; a communication frequency control unit that sets the communication frequency to a first communication frequency, uses the train location information obtained from the train through the polling communication to determine whether the train reaches a predetermined impending arrival range including a stop position at the station or not, and switches the communication frequency to a second communication frequency higher than the first communication frequency when the train reaches the impending arrival range; and a door-synchronized opening and closing time relay that communicates with the platform screen door control device at times of door opening and closing in synchronization, transmits, to the train through the polling communication, given synchronized opening and closing control instruction information received from the platform screen door control device, and transmits the vehicle state information obtained from the train through the polling communication, to the platform screen door control device.
