The emergency service is provided by making an emergency call to the other crew member on the same vehicle, the railway company center 100, the garage 110, etc. by voice and buzzer. The video is also broadcast to the railway company center 100.

  Thereby, it is possible to quickly cope with the emergency situation of the crew.

  In addition, when an emergency button is reported from the passenger cabin, the electric vehicle service center 300 makes a voice call to the on-board crew member, and in the case where the crew member (conductor) is unable to handle alone, the emergency crew member is transported to the crew, such as transporting the patient. It becomes possible to support.

  With this service, there are usually two crew members and several people on the Shinkansen, but there are hundreds to 2,000 passengers, so it is possible to quickly and safely cope with situations that cannot be handled by the crew alone. become.

  Next, the emergency response service 580 shown in FIG. 12 will be described.

  For electric vehicles, various information is useful during commercial operation and maintenance, but in the past, vehicle, equipment failure history, replacement history, hardware / software change / update history, distance between stations, Position data, wheel diameter, fluctuation of variable load, etc. are based on the premise that data is not easily extracted.

  In addition, it is necessary to study to introduce new technology to railways, but it is difficult for information to reach the railway company, and the explanation of the functions and handling of newly introduced equipment and systems has spread to the end workers. It is also assumed that it is difficult to do.

  In view of such circumstances, in this service, as shown in FIG. 4, the railway company side and the electric vehicle service company make an information service contract for a certain device or part of the electric vehicle 200. .

  In this service, various information is useful when an electric vehicle performs commercial operation and maintenance, and necessary information varies depending on the role. Therefore, the electric vehicle service center 300 has a terminal screen of the center of the railway company center 100 and the garage. 3, in the “information service” contract, what information, records, and data 6 of which vehicle the electric vehicle service center 300 has is displayed as a list.

  Examples include vehicle and device failure histories, replacement histories, hardware / software change / update histories, station-to-station distances, ground element position data, wheel diameters, fluctuations in applied loads, and various documents.

  From these, select the necessary data and documents.

  As a result, the selected data and document 6 are sent from the electric vehicle service center 300 as electronic information via the railway company center 100 that requested the information and the terminal 3 of the garage. For records that are updated daily, the recording period is specified.

  It is also possible to select information 6 with conditions such as information on only the designated vehicle. At present, useful data has not been extracted.

  Since the information stored in the storage device 6 of the electric vehicle service center 300 is associated and stored in a database, it is possible to search and retrieve information that meets the conditions.

  In addition, although it is necessary to consider introduction of new technology into the railway, it is difficult for information to reach the railway company center 100. Among the information to be provided, it is also possible to provide news introducing new technologies, newly introduced devices, system functions, handling videos, and the like.

  Furthermore, security is applied so that information on vehicles of other railway companies cannot be taken out. Usually, if it is information of a general partner, it can be considered as a homepage on the Internet, but the required partner is limited and there is security, so it can be provided by contract as a dedicated service.
