When the abnormality detection process is started, the control unit 41 (CPU) first analyzes the status information input from the display control device 20 with reference to the abnormality detection setting data 42b (step S101). The control unit 41 determines whether or not abnormal data is detected as a result of the analysis (step S102).
When it is determined that abnormal data has not been detected (“NO” in step S102), the process by the control unit 41 returns to step S101.

  If it is determined that abnormal data has been detected (“YES” in step S102), the control unit 41 then outputs a control signal for displaying the abnormality content on the abnormality display 50 (step S103). The control unit 41 refers to the corresponding operation table 42c and outputs, to the abnormality indicator 50, designation information related to the color of the LED lamp that is turned on by the abnormality indicator 50 according to the abnormality content.

  The control unit 41 creates a title and text of an abnormality notification e-mail related to the content type of the abnormality and the location where the abnormality has occurred according to a template predetermined in the corresponding operation table 42c (step S104). Further, the control unit 41 acquires and sets the transmission destination of the abnormality notification email stored in advance in the corresponding operation table 42c corresponding to the content type of the abnormality (step S105).

  The control unit 41 transmits a request for transmitting the abnormality notification e-mail created in the processes of steps S104 and S105 to each destination to the mail server 60 (step S106). And the process of the control part 41 returns to step S101.

  FIG. 7 is a flowchart showing a control procedure by the control unit 31 of the display device abnormality detection process executed by the operation guidance display device 30.

  This display device abnormality detection process is a resident process that is automatically called and started and continuously executed when the operation guidance display device 30 is activated. When the display device abnormality detection process is started, the control unit 31 (CPU) first analyzes an operation state of each unit of the operation guidance display device 30 (step S201). The control unit 31 outputs a control signal corresponding to the analysis result to the light emission drive unit 39, and controls the lighting state of the light emission unit 38 (step S202).

  Next, the control unit 31 determines whether or not an abnormality has been detected in the operating state (step S203). If it is determined that an abnormality has been detected (“YES” in step S203), the control unit 31 outputs a control signal to the display driving unit 37 and displays “Adjusting” in yellow on the display unit 36. This is performed (step S204). Then, the process by the control unit 31 returns to step S201.

  On the other hand, when it is determined that no abnormality has been detected (“NO” in step S203), the control unit 31 performs display driving of a control signal for performing display based on the display control signal acquired from the display control device 20. It outputs to the part 37 (step S205). Then, the process by the control unit 31 returns to step S201.

The mail server 60 is requested to send an electronic mail.
As a result, in this operation guidance display system S, the person in charge of repairing an abnormality or recovering a failure can quickly know the location and contents of the abnormality. It is possible to shorten the time until the start of the action related to. Moreover, since work can be started after confirming materials and tools necessary for restoration in advance, the restoration work can be performed efficiently.
On the other hand, the operation guidance display device 30 can detect an abnormality of the own device and a communication abnormality between the display control device 20 and the operation guidance display device 30. Then, in the case of indicating that the operation guidance cannot be displayed based on the control signal from the display control device 20, the display screen displays white “adjusting”, whereas in the case of an abnormality on the own device side In the case of “adjusting” in yellow autonomously under the control of the control unit 31. Thereby, in this operation guidance display system S, since it is possible to easily and immediately know that there is an abnormality on the side of the operation guidance display device 30, the repair person in charge can quickly find out. Recovery work can be performed.

  In particular, by informing the person in charge of the details of the necessary abnormality and the location of the abnormality using e-mail, the person in charge went to the machine room once to check the contents of the abnormality, or security that is not familiar with the technology. It is possible to suppress the occurrence of a problem that sufficient information cannot be acquired immediately due to uncertain telephone contact with a staff member, etc., and to display necessary information directly to the person in charge.

  In addition to providing the display control device 20 and the state monitoring device 40 completely separately and outputting a status signal from the display control device 20, the display control device 20 is not modified at all. The stability of the 20 operations is not impaired. Therefore, this state monitoring device 40 can be easily added to a conventionally operating system. Further, even if the state monitoring device 40 is connected to an external network, there is no concern that the security related to the display of the operation guide information will be reduced.

In particular, by displaying the “adjusting” display indicating an abnormality or trouble related to the operation guidance display in a different color between the case of the abnormality on the own device side and other cases, the details of the abnormality are directly indicated to the passenger. The person in charge can easily learn without showing in
Moreover, the display which shows the content of abnormality can be easily performed using the conventional operation guidance display apparatus, without adding the structure for showing the content of abnormality separately.

  In addition, the operation guidance display device 30 is provided with a light emitting unit 38, and in the case of an abnormality on the own device side, the lighting operation is performed with a different lighting pattern, for example, light is emitted in a color according to the content of the abnormality. Accordingly, the person in charge of the repair can work while knowing the details of the abnormality in real time on the spot. In particular, even if not all the on-site personnel who actually perform recovery work are included in the destination of the notification email, the details of the abnormality can be confirmed immediately on the spot, and many times during repairs There is no need to re-check the new anomaly notification email.

  In addition, a communication abnormality between the operation guidance display device 30 and the display control device 20, a communication impossible state due to an abnormality of the control unit 31, a display screen failure, a drive voltage abnormality, or a display impossible state on the display screen during recovery work, etc. Even in this case, the content of the abnormality can be notified with a simple configuration using the light emitting unit 38.

[Modification]
FIG. 8 is a block diagram illustrating a modification of the display control apparatus.

An operation guide setting unit 22 for setting contents to be displayed on the operation guide display device 30 and an operation guide display control unit 23 for outputting a display control signal based on the setting to each operation guide display device 30 in accordance with the switching timing of display contents. In addition to the above, each configuration excluding the control unit 41 of the state monitoring device 40 of the above-described embodiment is included. About the same structure, the same code | symbol is attached | subjected and description is abbreviate | omitted.
Here, also in the display control apparatus 20a of this modification, it is preferable that the data path for displaying the operation guidance information and the data path for notifying the occurrence of abnormality are provided independently.

  As described above, when the conventional display control device 20 itself can be improved, it is not necessary to additionally provide hardware related to state monitoring by integrally performing the operation related to state monitoring. In addition, it is possible to save one step of the trouble related to status data transfer.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, in the above-described embodiment, it is determined whether or not the communication to the operation guide display device 30 or the operation guide display device 30 is abnormal by changing the color of the character “under adjustment” in the operation guide display device 30. Although the distinction is displayed, the distinction is not limited to this. For example, it is also possible to make a distinction by blinking the “adjusting” display at a predetermined time period or changing the display position of “adjusting”. Here, it is possible to describe and display the specific contents of the abnormality on the operation guide display device 30, but since the display contents on the display screen are visually recognized by many passengers, direct display is not possible. It is more preferable that the method is a method of distinction that can be indirectly understood by the person in charge.

  Moreover, in the said embodiment, although the operation guidance display apparatus 30 provided with the display screen which can display full color LED was mentioned as an example, the operation guidance display apparatus which can be displayed only with a predetermined number of colors, or monochrome The present invention can be applied even to an operation guidance display device that can only display. In this case, display is performed within the range of colors that can be displayed, and when the types of colors are insufficient, it is possible to distinguish them by lighting patterns, display positions, and the like.

Moreover, in the said embodiment, although the light emission part 38 by the LED lamp which can display three colors was provided in the operation guidance display apparatus 30, the form of the light emission part 38 is another, ie, more colors. The display may be capable of being displayed, or may be capable of identifying the content of the abnormality by a lighting operation pattern in a single color display. Or even if there are a plurality of colors, the contents of the abnormality can be identified by the difference in the lighting pattern including the lighting order of each color. Alternatively, the light emitting unit 38 may not be provided if the person in charge can be sufficiently informed of the content of the abnormality with part or all of the display screen.
Here, when the content of the abnormality can be identified only by the light emitting unit 38, or when there is no need to immediately stop the operation guidance display due to the abnormality, only the light emitting unit 38 is informed of the abnormality while continuing the operation guidance display. It is also possible to perform a lighting operation. Thereby, it is possible to further suppress a decrease in service to the user.

Moreover, in the said embodiment, although the content of abnormality was delivered to the person in charge by abnormality notification electronic mail, delivery of information is not restricted to electronic mail. For example, by installing a predetermined application program in the external portable device 70 and performing a predetermined notification operation, for example, an operation of a vibration motor, and prompting a person in charge to make an HTTP connection to a predetermined website, The contents of the abnormality may be distributed. In this case, it is also possible to display a map of the location where the abnormality has occurred and to display the abnormal site.
In such a case, as the external portable device 70, for example, a tablet terminal or a smartphone is more preferably used as one that can sufficiently cope with such graphic display.

Further, in the above embodiment, the abnormality display 50 can display a plurality of colors (for example, three colors), and display in different colors according to the abnormality content. The display type by the display device 50 is not limited to this. For example, the person in charge at the station may be able to identify the blinking pattern of the same color or the difference in lighting positions of a plurality of lamps.
Here, the station staff in the station office obtains sufficient information related to the abnormality by reading the abnormality notification e-mail distributed from the mail server 60 to the external portable device 70 based on the request from the state monitoring device 40. I can do it. Therefore, it is not necessary to display information related to all abnormalities only with the abnormal indicator 50. In addition, if the station staff is notified of the occurrence of an abnormality by another method, or if the station staff can read the abnormality notification e-mail delivered to the station staff quickly and reliably, the abnormality indicator 50 is displayed at the station office. It does not have to be provided in the room.

Moreover, in the said embodiment, although it used about the display apparatus which shows the departure time of a railroad, it is not restricted to this. Other than the railway at the railway station, for example, a bus at a bus terminal or an aircraft at an airport may be used. In addition to the departure time, the arrival time may be displayed.
In addition, details such as the specific configuration, structure, operation content, and operation procedure described in the above embodiment can be changed as appropriate without departing from the spirit of the present invention.
