摘要： A data recorder capable of reducing adverse effects caused by radiation is provided. In one aspect of a data recorder of the present invention, an input interface includes a first buffer memory, the input interface accepts input of data from outside and records the data in the first buffer memory, a control unit switches a state of a power supply for non-volatile memory to an on state at a timing determined on the basis of an amount of data recorded in the first buffer memory and a mode of the input of the data from the outside via the input interface, the input interface transfers the data recorded in the first buffer memory to the non-volatile memory in a case where the power supply for non-volatile memory is in an on state, and the control unit switches the state of the power supply for non-volatile memory to an off state after transferring the data recorded in the first buffer memory to the non-volatile memory.

摘要： A railway-train communication apparatus provided in a railway train secures the adaptability to a transmission path having low signal quality and improves the certainty of data transmission. The railway-train communication apparatus includes a node device 21, which includes converters 31-1 and 31-2 that perform a mutual signal conversion between an HDLC signal flowing through an inter-car network constructed between cars of the railway train and an Ethernet (registered trademark) signal flowing through an in-car network constructed in each of the cars and switching hubs 32 arranged between the converters 31-1 and 31-2 and for respectively connecting the converters 31-1 and 31-2, and network controllers 22-1 and 22-2 that are connected to the switching hubs 32.
