It should be noted that the selection of the error classification considered appropriate or the reading of an identifier such as a two-dimensional barcode provided on the error classification card is not limited to one but may be a plurality.

FIG. 3 is an explanatory diagram showing an example of an error classification card. Human errors are classified into six in advance, and six error classification cards are created.
For example, as shown in FIG. 3, the six error classification cards CD31 to CD36 include at least a classification number NO31 (1 to 6), a classification name GN31, an explanation EX31 regarding the error classification, and an identifier ID31 of a two-dimensional barcode. Is printed. Alternatively, an RFID tag as the identifier ID31 is provided on the six error classification cards CD31 to CD36.

  More specifically, as shown in FIG. 4, the explanation of the error classification of the classification number 1 is “human error that intentionally acts”, and the explanation of the error classification of the classification numbers 2 to 6 is , "Human errors that are forgotten indiscriminately", "Human errors that are forgotten when work is interrupted", "Human errors that act with a belief", "Human errors that act unconsciously", "Classification number 1" "Human error not corresponding to ~ 5".

  In other words, crew members read the classification name and description of the error classification card and select an appropriate error classification, or read an identifier such as a two-dimensional barcode provided on the appropriate error classification card. And let the terminal device 1 input.

  When the terminal device 1 determines that the error classification is not input (step S21: No), the process returns to step S21. On the other hand, when the terminal device 1 determines that the error classification is input (step S21: Yes), the server device The information regarding the error classification input in 2 is transmitted (step S22).

  Further, the terminal device 1 determines whether or not the communication unit 15 has received the explanation information regarding the event corresponding to the error classification input from the server device 2 (step S23), and the error classification input from the server device 2 If it is determined that the explanation information related to the event corresponding to is not received (step S23: No), the process returns to step S23.

  On the other hand, when it is determined that the terminal device 1 has received the explanation information related to the event corresponding to the input error classification (step S23: Yes), the terminal device 1 displays the description information related to the event corresponding to the input error classification. 13 is displayed (step S24).

If the server device 2 determines that the information related to the error classification input from the terminal device 1 has not been received (step S51: No), the process returns to step S51.

  On the other hand, when the server device 2 determines that the information related to the error classification input from the terminal device 1 has been received (step S51: Yes), the server device 2 causes an event corresponding to the received information related to the error classification input Explanation information relating to the event (description information relating to one or more events) is read from the database 26 (step S52), and the explanation information relating to the read event is transmitted to the terminal device 1 (step S53).

Here, FIG. 6 is an explanatory diagram showing an example of the database 26 stored in the server device 2, and illustrates a database related to “classification number 1”.
For example, when the input error classification received from the terminal apparatus 1 is “classification number 1”, the server apparatus 2 transmits explanatory information (event, classification, generation factor, and result) regarding the event in FIG. To display. The transmission of the explanation information related to the event to the terminal device 1 may be a mode in which all items of the event, classification, generation factor, and result are transmitted, and each item is appropriately selected and transmitted.

  For this reason, crewmembers, etc., in step S25 of the flowchart of FIG. 2, refer to the explanatory information regarding the event as shown in FIG. It can be replaced.

  In addition, when the explanation information regarding the event as shown in FIG. 6 displayed in step S24 of the flowchart of FIG. By performing an operation of selecting an error classification, it is possible to compare and refer to explanatory information regarding an event related to another error classification.

  As described above, the terminal device 1 transmits information on the input error classification, and the server device 2 stores a preset error classification and explanation information on a plurality of events corresponding to the error classification from the database. Since the explanation information related to one or more events corresponding to the information related to the error classification transmitted from the terminal device 1 is read out and transmitted to the terminal device 1 to display the explanation information related to the one or more events. By entering the error classification, employees of the company can think about replacing them with similar events in their workplace while referring to the explanatory information on the one or more events, which caused various events in the railway. It is possible to assist in determining what error classification a human error belongs to.

(Modification 1)
[3-1. Different identifiers for each workplace, etc.]
In the description of the embodiment, one type of identifier such as a two-dimensional barcode or an RFID tag provided on the error classification card is read by the identifier reading unit 16, but an error classification card is separately provided for each workplace or work content. And a different identifier may be provided for each error classification card.

For example, even employees of the same railway company have different workplaces such as a station, a crew ward, a vehicle center, and a technical center, and different work contents such as station transportation, driving, vehicle inspection, track maintenance, and the like.
For this reason, even if it is an event that belongs to the same error category and is very easy for the crew to understand, it may be an event that is difficult to understand easily at other workplaces such as vehicle centers. is assumed.

  Accordingly, a separate error classification card is created for each workplace or work content, and different identifiers are provided for each error classification card, so that all explanatory information regarding events belonging to the same error classification is not transmitted from the server device 2 and displayed. In addition, the explanation information related to the event most suitable for the workplace or work content is extracted from the explanation information related to the event belonging to the same error category and displayed.

Specifically, the explanation information regarding the events belonging to the same error classification is further divided for each workplace or work content to construct a database.
For example, the explanation information regarding the event as shown in FIG. 6 is an event for the crew member, and therefore corresponds to the workplace where the crew member belongs and the work contents performed by the crew member in the database constructed in this way. Accumulating explanatory information about the event for the crew in the database.
Then, an error classification card is created for each workplace or work content, which is explanatory information related to events belonging to the same error classification as described above, and is printed by associating different identifiers for each database constructed in a divided manner.

  In this case, by using different identifiers for each workplace (for example, station, crew area, vehicle center, technical center, etc.) or work contents (for example, station transportation, driving, vehicle inspection, track maintenance, etc.), Because it is possible to extract and display explanatory information about the most suitable event for each workplace etc. from the database, it is possible to consider by replacing it with a similar event at your own workplace while referring to the explanatory information about the displayed event .

(Modification 2)
[3-2. Accumulation in database]
In the description of the embodiment, the error classification is entered, and the error classification is determined by replacing the similar classification with the event of the own workplace while referring to the explanation information regarding the event displayed on the display unit 13 of the terminal device 1. In addition to the explanation information about the event displayed in this way, the employees of the railway company newly input the explanation information about the event that the railway company experienced from the operation unit 12, and the information was newly input. The explanatory information regarding the event may be uploaded to the server device 2 and accumulated in the database 26.

  In this case, the employee of the railway company newly inputs, from the operation unit 12 of the terminal device 1 to the server device 2 and transmits to the server device 2 explanation information related to the event experienced by the railway company for the input error classification. By accumulating in the database 26, the information in the database 26 can be further enhanced and information can be shared with employees at other workplaces. It is possible to call attention to prevent an input event that may occur in the workplace.

  In addition, even for employees of the same railway company, error classification information may not be shared due to differences in branch offices, line districts, etc. By entering new information and storing it in the database, information can be shared between branch offices and across line sections.

  In the description of the embodiment, all the explanation information related to the event corresponding to the error classification received from the server device 2 is transmitted to the terminal device 1 and displayed. However, not only the classification number but also the classification number and other information are displayed. The server device 2 may extract explanation information related to the event from the database by combining with items (for example, event, classification, result, etc.), and may transmit the information to the terminal device 1 for display.

  In this case, if the database becomes large due to the accumulation of the database in the modified example 2, if explanatory information regarding all the events corresponding to the classification number (error classification) is displayed, a huge amount of information is displayed. Conversely, it is possible to prevent difficulty in grasping the event.

  In the description of the embodiment, it is described that human errors are classified into six in advance and six error classification cards are created. Of course, the number of error classifications may be any number, The explanation of the error classification is not limited to the contents illustrated in FIG.

  Further, in the description of the embodiment, a database that is a collection of cases in which events, classifications, generation factors, and results are accumulated for each error classification is illustrated, but of course, items that are accumulated corresponding to the error classification are It is not limited to events, classifications, generation factors, and results, but may include items such as date, time, season, region, and weather.

  In the description of the embodiment, the error classification card is printed with at least a classification number, a classification name, a description and an identifier regarding the error classification, and of course, other names such as a workplace name, a work name, a cautionary note, etc. The information may be printed together.
