The TID data receiving unit 11 receives TID data from the operation management device 20 every predetermined time, and outputs the received TID data to the TID data distribution unit 12.

  Upon receiving the TID data, the TID data distribution unit 12 generates change data indicating a difference from the most recently received TID data by comparing with the most recently received TID data, and stores the generated change data in the TID data storage While outputting to the part 14, the change data produced | generated via the transmission / reception part 13 are delivered to the information terminal device 40 as the latest train existing line information. In addition, distribution of change data is performed with respect to the information terminal device 40 which has received the update request, and when the connection request is received from the information terminal device 40, the latest TID data is used as the latest train line information. The information is distributed to the information terminal device 40.

  The transmission / reception unit 13 has a function of performing information communication with the information terminal device 40 via the Internet 30. The transmission / reception unit 13 distributes various requests received from the information terminal device 40 via the Internet 30 to the TID data distribution unit 12 or the reproduction data distribution unit 16 according to the type, and also transmits the TID data distribution unit 12 and the reproduction data distribution. The change data and TID data generated by the unit 16 are transmitted to the information terminal device 40 via the Internet 30. Further, the transmission / reception unit 13 manages downloading of various data files stored in the TID data storage unit 15 and uploading of the various data files to the TID data storage unit 15 by FTP (File Transfer Protocol).

  The information terminal device 40 is an information processing device that operates by program control, such as a personal computer having a communication function, and has a function of accessing the distribution server 10 via the Internet 30 (for example, a Web browser).

Return to A1.

  When the TID data is received from the operation management device 20 in step A1, the TID data distribution unit 12 generates change data indicating a difference from the TID data received immediately before by comparing the TID data with the most recently received TID data ( Step A6). Next, the TID data distribution unit 12 determines whether or not the update request received in step A2 is stored (step A7). When the update request is stored, the TID data distribution unit 12 distributes the generated change data to the information terminal device 40 that has received the update request (step A8), and the received TID data is the latest TID data. (Step A9) and return to step A1. When the update request is not stored, the TID data distribution unit 12 executes Step A9 and then returns to Step A1. The update request is deleted after the change data is distributed.

Next, the operation of the TID data storage unit 14 in the distribution server 10 will be described in detail with reference to FIG.
Referring to FIG. 5, the TID data storage unit 14 monitors the reception of change data from the TID data distribution unit 12 (step B1). When the update request is received from the information terminal device 40 in step B1, the TID data storage unit 14 performs a failure determination for determining whether or not a failure has occurred based on the input change data (step B2). It is determined whether or not there is a failure (step B3) and whether or not there is a failure (step B4).

  If there is a power failure in step B3, the TID data storage unit 14 stores time data and power failure failure data indicating a power failure along with the input change data, and returns to step B1. Further, if there is a power failure failure in step B4, the TID data storage unit 14 stores time fault data and failure failure data indicating failure failure together with the input change data, and returns to step B1. Further, if it is not a power failure or failure, time data is stored together with the input change data, and the process returns to step B1. In the present embodiment, the TID data storage unit 14 is configured to add time data. However, when the change data itself includes time data, it is not necessary to add time data. Further, the change data from the TID data storage unit 14 is stored, but the TID data at each time may be stored.

Next, the operation of the reproduction data distribution unit 16 in the distribution server 10 will be described in detail with reference to FIGS.

The reproduction data distribution unit 16 searches the reproduction display TID data stored in the TID data storage unit 15 when generating the time designation screen 70, so that the date / time data in which the reproduction display TID data is stored. And the failure data are acquired, and the reproduction date selection column 71 and the reproduction time selection column 72 of the time designation screen 70 are generated based on the acquired date and time data and failure data.
As shown in FIGS. 7D, 8A, and 8B, in the playback date selection column 71 and the playback time selection column 72, the playback date and playback time can be selected from a pull-down menu. The date and time of the reproduction display TID data stored in the TID data storage unit 15 is a selection item. Also, the date and time when the failure occurred based on the failure data is displayed separately from other dates and times by color or character type. It should be noted that the occurrence and type of failure may be indicated by a mark or the like. Thereby, it is possible to grasp the type of failure and the time of occurrence at the time of the reproduction start time designation operation on the time designation screen 70. For example, in the information terminal device 40, as shown in FIG. 8B, the TID screen 50 immediately before the occurrence of the failure is specified by designating the time before the occurrence of the failure and distributing the TID data before the occurrence of the failure. Can be displayed, and the train on-line state before the occurrence of the failure can be easily grasped.

  In the information terminal device 40, when the reproduction instruction button 73 on the time designation screen 70 is clicked to instruct reproduction disclosure of reproduction display, a time designation request is transmitted from the information terminal device 40 to the distribution server 10. When the time designation request is received from the information terminal device 40 in step C2, the reproduction data distribution unit 16 acquires TID data of the reproduction display start time designated by the time designation request from the TID data storage unit 15 (step C6). The acquired TID data is distributed to the information terminal device 40 that has received the time designation request (step C7). To the information terminal device 40 that has received the time designation request, change data after the reproduction display start time is sequentially delivered at designated intervals (step C8). Note that the interval at which the change data is distributed can be selected in the display speed selection field 63 of the reproduction instruction operation area 60 of the TID screen 50 as shown in FIG. Further, the TID screen 50 generated by the information terminal device 40 is configured to be easily recognizable as a replay display by changing the color and layout with the TID screen 50 generated by the TID data distribution unit 12. Is preferred.
