  • Publication number: 20210061325
    Abstract: A RIO device mounted to a train includes an output unit that outputs a signal to a relay mounted to the train, and a controller that controls whether or not to cause the output unit to output the signal. The output unit includes a readback circuit that detects whether or not the signal is outputted from the output unit. The controller makes a signal stop request and a signal output request to the output unit before operation of the train starts, acquires a detection result of the readback circuit while each of the signal stop request and the signal output request is performed, and detects abnormality of the output unit using the detection result.

  • Patent number: 9553931
    Abstract: A train-information managing apparatus receives a series of control information attached to serial numbers, which are transmitted from a central apparatus, in order of the transmission and carries out control in the order, and even when the central apparatus is changed or the serial numbers are reset, prevents a blank period of control from occurring. Therefore, when a reception serial number n included in received data is a preferential serial number (n?M) and an old number nprev, which is a serial number included in data received and stored last time, is a cyclic serial number (nprev?M+1), the train-information managing apparatus stores the received data.

  • Patent number: 9515944
    Abstract: A train information management apparatus includes a first system central device that generates first train control information for a car-mounted device in every predetermined period and a second system central device that generates second train control information starting from the time at which the time obtained by multiplying the predetermined period with 1/2 has elapsed from the time point when the first train control information is transmitted. The first system central device generates a first packet every time the first train control information is generated and alternately transmits a first packet to a first system trunk transmission line and a second system trunk transmission line. The second system central device generates and transmits a second packet almost in the same manner except that the second packet is transmitted to a trunk transmission line on the opposite side of the trunk transmission line to which the first packet was transmitted.
