It may be a driving site such as a dispatch station. The wireless communication means is not limited as long as it is a wireless means capable of transmitting information between the train information management device 2 and the treatment procedure management server 13. For example, in addition to train radio communication, communication means using millimeter waves can be considered.

  Next, an example of information transmitted and received between the train information management device 2 and the ground facility 11 will be described with reference to FIG.

  FIG. 3 is a diagram illustrating an example of information transmitted / received between the train information management device 2 and the ground facility 11. First, when a vehicle failure occurs, the train information management device 2 displays the failure part on the monitor display 3 and manages the failure code through the vehicle-side information transmission / reception device 5 and the ground-side information transmission / reception device 12. Transmit to the server 13. The train information management device 2 transmits a failure code to make a request for downloading a failure treatment manual corresponding to the failure code to the treatment procedure management server 13, and the treatment procedure management server 13 requests the requested failure treatment manual. Is transmitted to the train information management device 2. As described above, the train information management device 2 according to the present embodiment is connected to the treatment procedure management server 13 provided in the ground system via the wireless communication means, and is configured so that the latest failure treatment manual can be downloaded when a vehicle failure occurs. Has been.

  The failure treatment manual shows a treatment procedure corresponding to a failure code included in the train information, and this treatment procedure includes a vehicle failure phenomenon grasp item and a vehicle failure emergency treatment item.

  Hereinafter, specific examples of the phenomenon grasping items and the first aid items will be described. Here, as an example of a treatment procedure, for example, a treatment procedure for such a failure will be described in a case where the brake becomes instable due to some factor even though the driver weakens the brake.

  The phenomenon grasping item is, for example, whether the control power supply NFB (no fuse breaker) applied to the brake control device is ON, the current value supplied to the control power supply is a predetermined value or more, or the BC pressure is a certain value or more Phenomenon grasping items such as whether or not.

  Depending on the contents of the failure, there are a phenomenon grasping item that allows the train information management device 2 to automatically grasp the phenomenon, and a phenomenon grasping item that can grasp the phenomenon semi-automatically through the judgment by the crew. For example, if it is assumed that the above-described NFB state (whether it is ON or OFF) is a phenomenon grasping item that cannot be grasped by the train information management device 2, the train information management device 2 has this NFB installed. By displaying the name of the control panel and the name of the NFB on the monitor display 3, the crew member is prompted to confirm the NFB. At this time, the name of the control panel and the name of the NFB may be visualized and displayed not only by character information but also by a figure or the like.

  In addition, when there are a plurality of phenomenon grasping items, those phenomenon grasping items are configured in a flow chart as shown in FIG. 4 described later, and after the confirmation of one phenomenon grasping item is completed, You may comprise so that it may transfer to a phenomenon grasping | ascertainment item.

  The first-aid treatment item indicates the content of the first-aid treatment to be executed for the vehicle failure grasped by the phenomenon grasping item. The case where the brake is in an inrelaxed state in a predetermined vehicle 1 will be described as an example. By releasing the brake control device installed in the vehicle 1, the brake in the incompressible state is temporarily released. If it is possible, the train information management device 2 automatically transmits an opening request to the brake control device. That is, the train information management device 2 automatically executes an emergency measure for a vehicle failure. And the train information management apparatus 2 confirms that the requested | required operation | movement was performed by acquiring the response information from the brake control apparatus with respect to a releasing request | requirement. Furthermore, the train information management device 2 displays on the monitor display 3 that the brake control device has been released and, for example, a message prompting the crew to drive safely, such as “running below ΔΔ km / h” Is displayed.

  It should be noted that an operation that is assumed to have a great influence on the crew and passengers (for example, when the pantograph is lowered or when the cabin door is opened) must be confirmed by the crew. Therefore, with regard to emergency treatment items that may have a significant impact on the operation of such trains, the emergency treatment is performed by the crew by displaying a message prompting the treatment on the monitor display 3 in order to be treated by the crew. It may be configured to execute.

  Hereinafter, the operation of the train information management system according to the present embodiment centering on the train information management device 2 will be described with reference to FIG. In the following description of the operation, a case where a brake incompatibility occurs as described above will be described as an example of a failure.

  FIG. 4 is a flowchart showing the operation of the train information management system according to the present embodiment. When a failure of the brake control device occurs, the failure content and the failure occurrence site are displayed on the monitor display 3 (step S1). Furthermore, the train information management device 2 transmits a failure code and a vehicle number to the treatment procedure management server 13 (step S2). Thereafter, the train information management device 2 receives the failure treatment manual transmitted from the treatment procedure management server 13 (step S3).

  The failure treatment manual includes, for example, whether the NFB of the control power supply for the brake control device is ON, whether the current value supplied to the control power supply is greater than a predetermined value, It is assumed that a phenomenon grasping item such as whether this has occurred in all vehicles or only in a predetermined vehicle 1 is recorded.

  The train information management device 2 first determines whether, for example, the control power supply NFB is ON. When the NFB is ON (step S4, Yes), the operation of step S5 is executed. When the NFB is OFF (step S4, No), the operation of step S9 is executed.

  In step S5, the train information management device 2 determines whether or not the current value supplied to the control power supply is greater than or equal to a predetermined value. If the power supply current is greater than or equal to a predetermined value (step S5, Yes), the operation of step S6 is executed. If the power supply current is less than the predetermined value (step S5, No), the operation of step S8 is executed.

  Step S6 shows an example of an emergency treatment item when the value of the current supplied to the control power source is equal to or greater than a predetermined value. As an event at this time, for example, when the value of the power supply current supplied to the brake control device is higher than a predetermined value, an emergency measure that the NFB of the control power supply is turned off by the train information management device 2 is executed. Is done. On the other hand, when the value of the power supply current is lower than a predetermined value, an emergency measure is performed in which the NFB is turned off according to the determination of the crew.

  Furthermore, the train information management device 2 displays a message that the control power supply NFB is turned off on the monitor display 3 (step S7). By displaying such a message, for example, when the train information management device 2 turns off the NFB, the crew can confirm that the emergency treatment of the brake control device in which the failure has occurred has been executed. . Therefore, the burden on the crew member regarding the narrowing down of the phenomenon contents at the time of the failure occurrence and the emergency treatment corresponding to the phenomenon contents is reduced, and the crew member can respond calmly to the failure.

  Step S8 shows an example of a message displayed on the monitor display 3 when the current value is less than the predetermined value. As an event at this time, it is assumed that the brake control device has stopped because a current exceeding a predetermined value is not supplied to the control power supply. Here, it is assumed that the operation can be continued although there is no emergency measure to restore the power supply of the brake control device. Therefore, the train information management device 2 displays a message indicating that the operation can be continued on the monitor display 3 (step S8). In addition, you may make it display on the monitor display 3 that an inspection is required after an operation. By displaying such a message, the crew can continue to drive calmly.

  In step S9, for example, it is determined whether or not brake incompatibility has occurred in all the vehicles 1. This determination can be performed by the train information management device 2, but it may be confirmed visually by a crew member. In addition, as an event of “Step S4, No”, it is assumed that the brake control device has failed and works as fail-safe and the emergency brake is activated. When the brake incompatibility occurs in some vehicles 1 (step S9, No), the operation of step S10 is executed, and the brake incompatibility occurs in all vehicles 1 (step S9, Yes). Then, the operation of step S12 is executed.

  In step S10, as an example of an emergency treatment item when the brake incompatibility occurs in some of the vehicles 1, an emergency treatment of opening the brake control device for incompatibility of the brake is executed. As a specific emergency measure, for example, it is assumed that the pressure contained in the brake cylinder in the brake control device installed in the part of the vehicles 1 is forcibly exhausted to release the braking force.

  Furthermore, the train information management device 2 displays a message for prompting safe driving such as “running at ΔΔ km / h or less” on the monitor display 3 (step S11). By displaying such a message, the crew member can confirm that the emergency treatment of the brake control device has been executed, and can concentrate on safe driving.

  In step S <b> 12, as an example of an emergency treatment item when brake incompatibility occurs in all the vehicles 1, an operation of requesting relief from the ground facility 11 is executed. Such an operation makes it possible to shorten the time from the occurrence of a failure to the restoration of operation. Furthermore, the train information management device 2 displays a message such as “requesting relief” on the monitor display 3 (step S13). By displaying such a message, the crew can confirm that the rescue request is output by the train information management device 2.

  The measures after the first aid or display operation by the train information management device 2 are left to the crew, the commander, the inspector, etc., but the result of the first aid is displayed on the monitor display 3 or the monitoring terminal 14. Thus, for example, it is possible to continue operation when a vehicle failure is restored, arrange for a check-in crew, change a vehicle at a nearby station, arrange a rescue train, and the like.

  Moreover, you may comprise so that the content of the vehicle failure and the process progress by the train information management apparatus 2 may be recorded on the monitoring terminal 14. FIG. The monitoring terminal 14 can sequentially display the parameters before and after the occurrence of the failure and the result of the treatment for each troubled part, so that a vehicle inspector or the like can investigate the content of the treatment at a later date and improve the content of the failure treatment manual. Is possible. Here, the contents of the vehicle failure and the progress of the treatment by the train information management device 2 are recorded in the monitoring terminal 14, but these are recorded in the treatment procedure management server 13 and stored in the monitoring terminal 14. It may be a mode of display.

  With the exception of some vehicles 1 equipped with communication means capable of transmitting the vehicle state to the ground, many vehicles 1 use voice as a means for informing trainers and trainers stationed at the ground facility 11 There are many cases where mistakes and misunderstandings occur, and only one crew member can make calls on site, which is difficult to say as a reliable means of communication. . According to the train information management system according to the present embodiment, when a vehicle failure occurs, a commander or a repairman stationed at the ground facility 11 can monitor whether or not the failure treatment is appropriately performed. Appropriate advice and instructions can be given to the crew. Therefore, not only the operation of the first aid by the crew is greatly reduced, but the crew can also guide the passenger calmly.

  In addition, although step S4, step S5, and step S9 show the phenomenon grasping | assembling item in the case of a brake instability for convenience, in order to demonstrate operation | movement of the train information management system concerning this Embodiment, it is limited to these. Is not to be done. A plurality of failure treatment manuals corresponding to the failure codes are recorded in the treatment procedure management server 13, and the train information management device 2 grasps the phenomenon according to the phenomenon grasping items and the emergency treatment items indicated in the failure treatment manuals and the emergency treatment items. Measures shall be performed.

  The operation from step S9 to S11 is not limited to the case where the brake incompatibility occurs in only one vehicle, and can be applied to the case in which the brake incompatibility occurs in two or more vehicles 1. Yes, the operation of step S9 and step S12 is not limited to the case where the brake incompatibility occurs in all the vehicles 1, but also applies to the case where the brake incompatibility occurs in two or more vehicles 1. Is possible.

  Further, the treatment result by the train information management device 2 may be configured to be displayed on the monitoring terminal 14 in the ground facility 11 via the vehicle upper information transmission / reception device 5 and the ground side information transmission / reception device 12. As a result, the commander and the inspector stationed at the ground facility 11 can monitor whether or not the failure treatment is properly performed, and can give appropriate advice and instructions to the crew.
