  • Publication number: 20210323593
    Abstract: The wireless relay device according to the present disclosure includes: a reception unit to receive train control information; an information classification unit to classify the train control information into first control information requiring immediacy and second control information not requiring immediacy; a message generation unit to generate one message from the first control information contained in a piece of the train control information and to generate one message from a plurality of pieces of the second control information contained in a plurality of pieces of the train control information; and a transmission unit to transmit the messages generated by the message generation unit. With this configuration, it is possible to reduce the number of the data transfer messages which does not require immediacy while the instantaneous communication for the control information which requires immediacy is maintained.

  • Publication number: 20200083918
    Abstract: An interference detection apparatus in a wireless system that includes a plurality of wireless sensors that transmits sensor information wirelessly and a wireless signal measurement apparatus that measures power of a wireless signal of a frequency used by the wireless sensors for transmitting the sensor information. The interference detection apparatus includes an information processor; an interference position detector; and an interference avoidance method decider. The information processor determines a lack in reception of the sensor information transmitted from each of the wireless sensors. The interference position detector acquires a histogram that is created for a predetermined power measurement period and indicates time occupancy in the power measurement period of each of classes of classified power values.
