Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.
Embodiment 1.
First, referring to FIG. 1, a schematic configuration of a display control system 1 according to the first embodiment will be described. FIG. 1 is a block diagram showing a schematic configuration of the display control system 1 according to the first embodiment. As shown in FIG. 1, the display control system 1 includes a database DB1, a display control device 10, and a terminal 20, which are communicatively connected to each other. The display control system 1 according to the first embodiment is a system for supporting the work of a worker by displaying information on the display unit 21 of the terminal 20 that is acquired by the display control device 10 based on input signals from the database DB1, the terminal 20, and an external device communicatively connected via a network (not shown). For example, the display control system 1 is a system used in a railway company to support work related to railway operation.

Database DB1 accumulates and stores work information, which is information related to work performed by workers. For example, database DB1 accumulates and stores multiple pieces of work information related to work performed by station staff at railway stations. Specifically, database DB1 accumulates and stores multiple pieces of work information related to work performed by station staff to restore railway service in the event of a disruption. In the first embodiment, database DB1 only needs to be configured to store work information related to work performed by at least some worker, and may be configured to store information other than the work information used in display control system 1. Details of the work information will be described later.

As shown in FIG. 1, the terminal 20 includes a display unit 21 and an input unit 22. The input unit 22 receives an input operation by an operator of the terminal 20 and outputs a signal corresponding to the input operation to the display control device 10. For example, the input unit 22 is configured by an input device consisting of any one or a combination of a keyboard, a mouse, a touch panel, a microphone, etc., and the input operation may be an operation of a keyboard, a mouse, a touch panel, or a voice input to a microphone. Note that the operator is not limited to a person, but may be a system including a device such as AI (Artificial Intelligence), or may include both such a system and a person. For this reason, the signal output from the input unit 22 to the display control device 10 may be a control signal of the display control device 10 generated by another device, or may be a combination of such a control signal and a signal based on a human input operation. The display unit 21 displays an image corresponding to an input signal from the display control device 10 and an image corresponding to an input operation received by the input unit 22. For example, the display unit 21 is configured with a liquid crystal panel, an organic or inorganic EL (Electroluminescence) panel, or other display device.

The display control device 10 is a device for controlling the content to be displayed on the display unit 21 of the terminal 20 based on the database DB1 and an input signal from the terminal 20. As shown in FIG. 1, the display control device 10 includes a work information acquisition unit 11, an operation information acquisition unit 12, and a display control unit 13.

The work information acquisition unit 11 acquires work information related to work performed by workers during a period until a specific facility changes from a first state to a second state different from the first state. For example, the work information acquisition unit 11 refers to information stored in the database DB1, and acquires from the database DB1 work information related to work performed by station staff as workers at a specific station during a period until a facility, a railway, changes from a non-normal state as a first state in which operation is not normal to a normal state as a second state in which operation is normal. In other words, the work information acquisition unit 11 acquires from the database DB1 work information related to recovery work performed by station staff at a specific station during a period from a state in which operation is disrupted, such as a state in which a railway is delayed, to a state in which operation of the railway is restored. The work information acquired by the work information acquisition unit 11 from the database DB1 may be determined from a change in a specific facility, or may be inferred using not only the change in a specific facility but also the history and degree of the change, personnel at other stations, and the like. In the following description, the period during which the equipment changes from a first state to a second state different from the first state is also referred to as a specific period. Details of the work information will be described later.

The operation information acquisition unit 12 acquires operation information indicating an input operation by an operator of the terminal 20. For example, the operation information acquisition unit 12 acquires operation information indicating an input operation by the operator of the terminal 20 to the input unit 22, which is an input operation for changing information displayed as an image on the display unit 21. For example, the operator of the terminal is a commander at a railway control center who gives instructions to station staff, vehicle crew, and other workers. Also, for example, the operator of the terminal is a manager of station staff, crew, etc. who gives instructions to station staff at a specific station. The operator of the terminal and the worker performing the work may be one person or multiple people, and the operator of the terminal and the worker performing the work may be partly or entirely the same person.

The display control unit 13 causes the display unit 21 to display various information based on the operation information acquired by the operation information acquisition unit 12 and the information acquired by the work information acquisition unit 11. For example, the display control unit 13 causes the display unit 21 to display the work information acquired by the work information acquisition unit 11 based on the operation information acquired by the operation information acquisition unit 12. In other words, the display control unit 13 controls the display unit 21 to display a work display indicating the work information acquired by the work information acquisition unit 11 based on the operation information acquired by the operation information acquisition unit 12. Specifically, the display control unit 13 causes the display unit 21 to display a work display so as to switch the display content between two or more pieces of work information that differ according to the progress of the work based on the operation information. In other words, the display control unit 13 causes the display unit 21 to display the first work display and the second work display so as to switch between a first work display showing work information corresponding to a first progress of the worker's work and a second work display which has a different appearance from the first work display and shows work information corresponding to a second progress of the work which is different from the first progress, based on the operation information.

For example, the first work display is a display that prominently displays, among multiple work processes performed by the worker, a work process performed by the worker when the work progress is at a first progress, and the second work display is a display that prominently displays, among multiple work processes performed by the worker, a work process performed by the worker when the work progress is at a second progress. This allows the worker to easily grasp the work information according to the work progress by the operator of the terminal 20 conveying the display content of the display unit 21 to the worker, or by the worker directly looking at the display unit 21 of the terminal 20.

In addition, the display control unit 13 causes the display unit 21 to display a progress display that is a display regarding the progress of the work performed by the worker. In other words, the display control unit 13 causes the display unit 21 to display a progress display that changes according to the progress of the work performed by the worker. For example, the display control unit 13 causes the display unit 21 to display a first progress display that is a display regarding the first progress of the work together with the first work information, and causes the display unit 21 to display a second progress display that is a display regarding the second progress of the work together with the second work information. In other words, the display control unit 13 causes the display unit 21 to display the first progress display alongside the first work information, and causes the display unit 21 to display the second progress display alongside the second work information.

For example, the second progress display is a display that looks different from the first progress display, and is a display that allows the operator of the terminal 20 to visually understand that the work progress indicated by the second work display is a second progress that is different from the first progress. Specifically, the first progress display is a display that shows the time when the worker's work progress is the first progress, and the second progress display is a display that shows the time when the worker's work progress is the second progress. Details of the content that the display control unit 13 causes to be displayed on the display unit 21 will be described later.

Next, the hardware configuration of the display control device 10 according to the first embodiment will be described with reference to Figures 2 and 3. Figure 2 is a block diagram showing an example of the hardware configuration of the display control device 10 according to the first embodiment, and Figure 3 is a block diagram showing an example of a hardware configuration different from that shown in Figure 2 of the display control device 10 according to the first embodiment. For example, as shown in Figure 2, the display control device 10 has a processor 10a, a memory 10b, and an I/O port 10c, and is configured so that the processor 10a reads and executes a program stored in the memory 10b. The memory 10b may be, for example, a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM. The memory 10b may also be a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like. Furthermore, the memory 10b may be an HDD or SSD.

For example, as shown in FIG. 3, the display control device 10 has a processing circuit 10d and an I/O port 10c, which are dedicated hardware. The processing circuit 10d is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, a system LSI (Large-Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination of these. Each function of the display control device 10 is realized by the processor 10a or the processing circuit 10d, which is dedicated hardware, executing a program that is software, firmware, or a combination of software and firmware.

Next, referring to Figs. 4 to 6, the process performed by the display control device 10 to display various information on the display unit 21 will be described. Fig. 4 is a flowchart showing the process performed by the display control device 10 according to the first embodiment. As shown in Fig. 4, when the display control device 10 starts the process, first, the work information acquisition unit 11 acquires work information (step ST11). In this process, the display control device 10 acquires work information, which is information to be displayed on the display unit 21. For example, in this process, the display control device 10 acquires work information related to work performed by station staff at a specific station during a specific period until the railway service is restored, as work information to be displayed on the display unit 21. Specifically, the work performed by station staff at a specific station during a specific period until the railway service is restored includes reporting and contacting the outside, guiding passengers, and checking the site. When the process of step ST11 is performed, the display control device 10 displays the first work display and the first progress display on the display unit 21 (step ST12).

5 is a diagram showing a first work display S1 and a first progress display T1 that the display control unit 13 in the first embodiment causes to be displayed on the display unit 21. As shown in FIG. 5, for example, the first work display S1 that the display control unit 13 causes to be displayed on the display unit 21 includes a work content display S11 showing a plurality of work processes performed by station staff, and a predicted time display S12 showing a predicted time until each work is completed. For example, the first work display S1 includes a display showing a work process of "reporting to the police and fire department" which is a first work process corresponding to the first progress among the plurality of work processes, and a display showing work processes corresponding to other progresses. For example, in the first work display S1, work processes corresponding to other progresses other than the first work process include a work process of encouraging other workers to request assistance, a work process of checking the site, etc.

In addition, for example, the display "Please notify the police and fire department", which is a display indicating the first work step of the first work display S1, "Notify the police and fire department", is displayed on the display unit 21 in a manner different from displays indicating other work steps. Specifically, the first work display S1, which is a display indicating the first work step among a plurality of work steps, "Please notify the police and fire department" is displayed on the display unit 21 in a manner that is more noticeable than displays indicating work steps subsequent to the first work step.

Specifically, the display indicating the first work process is displayed in bolder, larger, darker, or more conspicuous characters than the displays indicating the other work processes. Conspicuous characters are, for example, characters with higher saturation than the characters in the displays indicating the other work processes, white-out characters, characters in multiple colors, characters whose color changes over time, characters with a larger color difference from the background than the characters in the displays indicating the other work processes, etc. Characters with a larger color difference from the background than the characters in the displays indicating the other work processes may be characters with a different color than the characters in the displays indicating the other work processes, or characters with the same color as the characters in the displays indicating the other work processes but with a different color background than the characters in the displays indicating the other work processes, resulting in a larger color difference from the background than the characters in the displays indicating the other work processes.

For example, the first progress display T1 that the display control unit 13 causes the display unit 21 to display is an image that functions as a time slider, and includes an axis portion T11 formed in a straight line, a slider portion T13 that moves along the axis portion T11, and a time display portion T12 that shows the time corresponding to the position of the slider portion T13 on the axis portion T11. Thus configured, the first progress display T1 is capable of showing the time corresponding to the first progress, with the slider portion T13 positioned at a position corresponding to the first progress.

As shown in FIG. 4, when the process of step ST12 is performed, the display control device 10 judges whether or not there has been an input operation to switch the work display displayed on the display unit 21 (step ST13). In this process, the display control device 10 judges whether or not the operator of the terminal 20 has performed an input operation to switch the work display displayed on the display unit 21 from the first work display S1 corresponding to the first progress to the second work display corresponding to the second progress. For example, the input operation to switch the work display displayed on the display unit 21 is an input operation to switch the display performed on a keyboard, mouse, touch panel, microphone, etc. Specifically, the input operation may be a voice input such as "I want to check the situation at the time of recovery" to a microphone. In addition, for example, the first progress display T1 may be an image that functions as a user interface whose display content changes according to the input operation of the operator. In this way, when the first progress display T1 functions as a user interface, the input operation to switch the work display displayed on the display unit 21 is an input operation in which the operator moves the slider part T13 along the axis part T11.

In the processing of step ST13, if an input operation is performed to switch the work display displayed on the display unit 21 (YES in step ST13), the display control device 10 causes the display unit 21 to display the second work display and the second progress display instead of the first work display S1 and the first progress display T1 (step ST14).

6 is a diagram showing a second work display S2 and a second progress display T2 that the display control unit 13 in the first embodiment causes to be displayed on the display unit 21. As shown in FIG. 6, for example, the second work display S2 that the display control unit 13 causes to be displayed on the display unit 21 includes a work content display S11 showing a plurality of work processes to be performed by station staff and a predicted time display S12 showing a predicted time until each work process is completed, similar to the first work display S1, but is displayed to look different from the first work display S1. For example, the second work display S2 displays on the display unit 21 a display showing the work process "request assistance from guides", which is the second work process corresponding to the second progress among the plurality of work processes, in a manner different from that of the first work display S1.

Specifically, in the second work display S2, an indication indicating the second work process, "Request support from a guide," which is one of the multiple work processes, is displayed on the display unit 21 in a manner different from that of the first work display S1. More specifically, in the second work display S2, an indication indicating the second work process, "Request support from a guide," which corresponds to the second progress, which is a work process later than the first work process, is displayed on the display unit 21 in a manner more prominent than the indications indicating work processes later than the second work process. A specific example of displaying the indication indicating the second work process in a prominent manner in the second work display is similar to the specific example of displaying the indication indicating the first work process in a prominent manner in the first work display, and therefore a description thereof will be omitted.

For example, the display control unit 13 also changes the time indicated by the predicted time display S12 to correspond to the progress of the work display displayed on the display unit 21. This enables the worker to know the end time of the work according to the progress of the work.

Also, for example, the second progress display T2 that the display control unit 13 causes the display unit 21 to display is an image that functions as a time slider, similar to the first progress display T1, and includes an axis portion T11 formed in a straight line, a slider portion T13 that moves along the axis portion T11, and a time display portion T12 that shows the time corresponding to the position of the slider portion T13, while being displayed to look different from the first work display S1. Specifically, the second progress display T2 has the slider portion T13 positioned at a position corresponding to the second progress, and shows the time corresponding to the second progress. When the processing of step ST14 has been performed, and when there has been no input operation to switch the work display displayed on the display unit 21 in the processing of step ST13 (NO in step ST13), the display control device 10 ends the processing.

In addition, in the processing of step ST13, the input operation to switch the work display displayed on the display unit 21 is not limited to an operation to switch the progress of the work information and progress information displayed on the display unit 21, but may be an input operation to change the work information based on information acquired by the operator or the terminal 20. For example, when the worker performs an input operation on the input unit 22 to change the work information acquired by the work information acquisition unit 11 based on information affecting the progress of the work acquired by the operator, the work information acquisition unit 11 may update the work information acquired based on the input operation, or may acquire new work information based on the input operation. In other words, the work information acquisition unit 11 may be configured to acquire work information based on the operation information acquired by the operation information acquisition unit 12.

As described above, the display control device 10 according to the first embodiment comprises a work information acquisition unit 11 that acquires work information related to work performed by a worker during a specific period until the equipment changes from a first state to a second state, an operation information acquisition unit 12 that acquires operation information indicating an input operation by an operator, and a display control unit 13 that causes the display unit 21 to display a first work display S1 indicating work information corresponding to a first progress of the work, a second work display S2 indicating work information corresponding to a second progress of the work, a first progress display T1 related to the first progress of the work, and a second progress display T2 related to the second progress of the work, and the display control unit 13 switches between a state in which the first work display S1 and the first progress display T1 are displayed on the display unit 21 and a state in which the second work display S2 and the second progress display T2 are displayed on the display unit 21 based on the operation information.

Configured in this manner, the display control device 10 displays on the display unit 21, among multiple pieces of work information, work information that corresponds to the progress of the work based on the operator's input operation, making it possible for the worker to easily obtain work information that corresponds to the progress of the work, thereby improving the worker's work efficiency compared to the conventional method.

Furthermore, the display control device 10 according to embodiment 1 causes the display unit 21 to display a first progress display T1 relating to the first progress of the work together with the first work display S1, and causes the display unit 21 to display a second progress display T2 relating to the second progress of the work together with the second work display S2. Thus configured, the display control device 10 is able to visually indicate that the first work display S1 and the second work display S2 are at different progresses by the first progress display T1 and the second progress display T2, enabling the worker to easily obtain work information according to the progress of the work.

In addition, the first progress display and the second progress display in embodiment 1 are displays that differ from each other in appearance so that it is possible to distinguish which display is the future progress. For example, the first progress display and the second progress display are displays that indicate different specific times in a specific period. This allows the display control device 10 to easily distinguish, by the first progress display T1 and the second progress display, which display of the first work display S1 and the second work display S2 is the future progress or the future progress, making it possible for the worker to easily obtain work information according to the progress of the work.

In the first embodiment, the display control device 10 is configured to display on the display unit 21 work information related to work performed by station staff as workers at a specific station during a period when a railway, which is a facility, changes from a non-normal state in which operation is not normal to a normal state in which operation is normal, but is not limited to this. The facility does not have to be a railway, but may be a building, a facility, a vehicle, a ship, an aircraft, or the like, a transportable device, or a movable body. For example, the display control device may be configured to display on the display unit 21 work information related to work performed by a crew member, a mechanic, or a commander during a period when a bus, which is a facility, changes from a non-normal state in which operation is not normal to a normal state in which operation is normal. Also, for example, the display control unit may display information on multiple different pieces of equipment in a linked manner on the display unit 21, or display information on multiple pieces of equipment simultaneously.

The display control device may also be configured to display on the display unit 21 provided in the vehicle work information related to the work performed by the driver during the period until the vehicle, which is the equipment, changes from the abnormal state to the normal state. In such a case, the abnormal state may be a state in which the road on which the vehicle is traveling is congested, and the normal state may be a state in which the road on which the vehicle is traveling is not congested, or the abnormal state may be a state in which the vehicle is not maintained, and the abnormal state may be a state in which the vehicle is maintained.

The display control device may also be configured to cause the display unit 21 to display work information related to maintenance or inspection work performed by workers during the period until the equipment, an elevator or escalator, changes from an abnormal, non-normal state to a normal, normal state. In such a case, the state in which the equipment requires inspection may be the abnormal state, and the state in which the equipment inspection has been completed may be the normal state.

The display control device may also be configured to display on the display unit 21 work information related to work performed by production personnel during the period when the equipment, which is an industrial product, changes from a state in which production has begun to a state in which production has been completed, or may be configured to display on the display unit 21 work information related to work performed by inspectors during the period when the equipment, which is an industrial product, changes from a state in which inspection is required to a state in which inspection has been completed.

In addition, in the first embodiment, the work information acquisition unit 11 is configured to acquire work information related to the work performed by the worker from the database DB1, but is not limited thereto. The work information acquisition unit may be configured to acquire work information from a source other than the database DB1. For example, the work information acquisition unit may be configured to acquire work information from the terminal 20, or may be configured to acquire work information based on an input operation performed by an operator of the terminal 20 on the input unit 22, or may be configured to acquire work information from an external device (not shown) that is communicatively connected to the display control device via a network, or may be configured to acquire work information from a storage unit (not shown) that is provided in the display control device and stores information.

In addition, in embodiment 1, the progress display that the display control device 10 displays on the display unit 21 is not limited to the one described above, and a variety of other displays are possible.

Embodiment 2.
Next, a display control system according to embodiment 2 will be described with reference to Fig. 7. The display control system according to embodiment 2 is different from the display control system 1 according to embodiment 1 in that the display that the display control unit causes the display unit 21 to display is different, but other configurations are the same, and the same reference numerals are used to designate the same configurations as those in embodiment 1, and description thereof will be omitted.

7 is a diagram showing the first work display and the first progress display that the display control unit according to the second embodiment causes the display unit 21 to display. As shown in FIG. 7, the display control unit according to the second embodiment causes the display unit 21 to display the button T14 as a user interface used to display the second work display S2 and the second progress display T2 on the display unit 21 instead of the first work display S1 and the first progress display T1. For example, when the operator performs an input operation to operate the button T14, the display control unit causes the display unit 21 to display the work information so that the progress of the work information changes as the slider unit T13 moves along the axis unit T11. Also, for example, when the operator performs an input operation to operate the button T14 in a state in which the work information is displayed on the display unit 21 so that the progress of the work information changes as the slider unit T13 moves along the axis unit T11, the display control unit causes the display unit 21 to display the work information so that the movement of the slider unit T13 along the axis unit T11 stops and the change in the work information stops.

As a result, the display control device of embodiment 2 is capable of displaying the work display and progress display on the display unit 21 so that the work display and progress display change with the passage of time or progress even when the operator is not performing an operation, thereby enabling the worker to know the changes in the work information according to the progress.

Embodiment 3.
Next, a display control system according to embodiment 3 will be described with reference to Fig. 8. The display control system according to embodiment 3 is different from the display control system according to embodiment 2 in the progress display that the display control unit causes the display unit 21 to display, but other configurations and other display contents of the display unit 21 are similar, and the same reference numerals are used to designate the same configurations as those in embodiment 2, and description thereof will be omitted.

Figure 8 is a diagram showing the first task display S1 and the first progress display T3 that the display control unit in embodiment 3 causes to be displayed on the display unit. As shown in Figure 8, the display control unit in embodiment 3 causes the display unit 21 to display the first task display S1 and the first progress display T3. The first progress display T3 that the display control unit causes to be displayed on the display unit 21 is an image that functions as a time slider, and includes an axis portion T11 formed in a straight line, a slider portion T13 that moves along the axis portion T11, a time display portion T12 that shows the time corresponding to the position of the slider portion T13 on the axis portion T11, and one or more specific time displays T15 that correspond to positions other than the position of the slider portion T13.

For example, the specific time display T15 is a display that indicates the time corresponding to a specific position on the axis T11 when the slider portion T13 moves along the axis T11. The specific time display T15 may be arranged at a position on the axis T11 that corresponds to the predicted time when each work process will be completed, and may be a display that indicates the predicted time. Since the difference between the first progress display and the second progress display in embodiment 1 is similar to the difference between the first progress display and the second progress display in embodiment 3, a description of the second progress display in embodiment 3 will be omitted.

Configured in this manner, the display control device of embodiment 3 displays the first progress display T3 on the display unit 21 together with the first work display S1, making it possible to easily grasp the progress of work based on the positional relationship between the slider portion T13 and the specific time display T15.

Embodiment 4.
Next, a display control system according to embodiment 4 will be described with reference to Fig. 9. The display control system according to embodiment 4 is different from the display control system according to embodiment 2 in the progress display that the display control unit causes the display unit 21 to display, but other configurations and other display contents of the display unit 21 are similar, and the same reference numerals are used to designate the same configurations as those in embodiment 2, and description thereof will be omitted.

9 is a diagram showing the first task display S1 and the first progress display T4 that the display control unit according to the fourth embodiment causes the display unit to display. As shown in FIG. 9, the display control unit according to the fourth embodiment causes the display unit 21 to display the first task display S1 and the first progress display T4. The first progress display T4 that the display control unit causes the display unit 21 to display is an image that functions as a time slider, and includes an axis portion T11 formed in a straight line, a slider portion T13 that moves along the axis portion T11, a time display portion T12 that indicates the time corresponding to the position of the slider portion T13 on the axis portion T11, and one or more specific information displays T16, T17 that correspond to positions other than the position of the slider portion T13. The specific information displays T16, T17 are displays that indicate information about the time that a specific position on the axis portion T11 corresponds to when the slider portion T13 moves along the axis portion T11.

For example, the specific information displays T16 and T17 are displays that show information about the state of the equipment at a time corresponding to a specific position on the shaft portion T11 when the slider portion T13 moves along the shaft portion T11. Also, for example, the specific information displays T16 and T17 are displays that show information about the expected work process at a time corresponding to a specific position on the shaft portion T11 when the slider portion T13 moves along the shaft portion T11. Since the difference between the first progress display and the second progress display in embodiment 1 is similar to the difference between the first progress display and the second progress display in embodiment 4, a description of the second progress display in embodiment 4 will be omitted.

Configured in this manner, the display control device of embodiment 4 displays the first progress display T4 on the display unit 21 together with the first work display S1, thereby enabling the worker to easily grasp the progress of the work based on the positional relationship between the slider portion T13 and the specific information displays T16, T17 and the information indicated by the specific information displays T16, T17.

Embodiment 5.
Next, a display control system according to embodiment 5 will be described with reference to Fig. 10. The display control system according to embodiment 5 is different from the display control system according to embodiment 2 in the progress display that the display control unit causes the display unit 21 to display, but other configurations and other display contents of the display unit 21 are similar, and the same reference numerals are used to designate the same configurations as those in embodiment 2, and description thereof will be omitted.

Figure 10 is a diagram showing a first work display S1 and a first progress display T5 that are displayed on the display unit 21 by the display control unit according to embodiment 5. As shown in Figure 10, the display control unit according to embodiment 5 displays the first work display S1 and the first progress display T5 on the display unit 21. The first progress display T5 that the display control unit displays on the display unit 21 is an image showing which of a plurality of work processes the worker is required to perform, and is an image for showing the progress of the work by showing the required work process. In Figure 10, "STEP 1", "STEP 2", "STEP 3", "STEP 4", and "STEP 5" correspond to the work processes with the first progress to the fifth progress, respectively, among the plurality of work processes.

For example, when the work progress is the first progress corresponding to "STEP 1", the display control unit in embodiment 5 causes the display unit 21 to display "STEP 1" to "STEP 5" as the first progress display T5, and also causes the display unit 21 to display "STEP 1" in a manner different from the other displays of "STEP 2" to "STEP 5".

Also, for example, when an input operation is performed to select a work process corresponding to one of "STEP 2" to "STEP 5" while the first work display S1 and the first progress display T5 are displayed on the display unit 21, the display control unit according to the fifth embodiment causes the display unit 21 to display a work display and progress display corresponding to the selected work process in place of the first work display S1 and the first progress display T5. Specifically, when an input operation is performed to select a work process corresponding to "STEP 2" while the first progress display T5 is displayed on the display unit 21, the display control unit according to the fifth embodiment causes the display unit 21 to display a second work display and a second progress display in place of the first work display S1 and the first progress display T5. For example, the second progress display is a display that causes the display unit 21 to display "STEP 1" to "STEP 5", and causes the display unit 21 to display the displays of "STEP 1" and "STEP 2" in a manner different from the other displays of "STEP 3" to "STEP 5". Furthermore, for example, the display control unit in embodiment 5 causes the display unit 21 to display the work display and progress display so that the work display and progress display change with the passage of time or progress when the operator is not performing an operation.

Configured in this manner, the display control device of embodiment 5 can more clearly indicate the progress of work corresponding to the work display by displaying the first progress display T5 on the display unit 21 together with the first work display S1, making it possible for the worker to easily grasp the progress of the work.

Embodiment 6.
Next, a display control system according to embodiment 6 will be described with reference to Fig. 11. The display control system according to embodiment 6 is different from the display control system according to embodiment 2 in the progress display that the display control unit causes the display unit 21 to display, but other configurations and other display contents of the display unit 21 are similar, and the same reference numerals are used to designate the same configurations as those in embodiment 2, and description thereof will be omitted.

11 is a diagram showing the first task display S1 and the first progress displays T1 and T5 that the display control unit according to the sixth embodiment causes the display unit 21 to display. As shown in FIG. 11, the display control unit according to the sixth embodiment causes the display unit 21 to display the first task display S1 and the first progress displays T1 and T5. The display control unit according to the sixth embodiment may be configured to display the button T14 according to the second embodiment on the display unit 21 in addition to the first progress displays T1 and T5 together with the first task display S1. In addition, the content of the second progress display that the display control unit according to the sixth embodiment causes the display unit 21 to display based on an input operation when the first progress display is displayed on the display unit 21 is the same as the second progress display according to the first embodiment and the second progress display according to the fifth embodiment, and therefore will not be described.

Configured in this manner, the display control device of embodiment 6 displays the first progress displays T1, T5 on the display unit 21 together with the first work display S1, thereby more clearly indicating the progress of the work corresponding to the work display compared to a case in which only one of the first progress display T1 and the first progress display T5 is displayed on the display unit 21, making it possible for the worker to easily grasp the progress of the work.

Embodiment 7.
Next, a display control system according to embodiment 7 will be described with reference to Fig. 12. The display control system according to embodiment 7 is different from the display control system according to embodiment 1 in the progress display that the display control unit causes the display unit 21 to display, but other configurations and other display contents of the display unit 21 are the same, and the same reference numerals are used to designate the same configurations as those in embodiment 1, and description thereof will be omitted.

12 is a diagram showing the first work display S1 and the first progress display T7 that the display control unit according to the seventh embodiment causes the display unit 21 to display. As shown in FIG. 12, the display control unit according to the seventh embodiment causes the display unit 21 to display the first work display S1 and the first progress display T7. The first progress display T7 is a display showing the time when the progress of the worker's work is the first progress, for example, the first progress display T7 is an image of an analog clock showing the time when the progress of the worker's work is the first progress. For example, the first progress display T7 is an image that functions as a user interface whose display content changes in response to an input operation by the operator, and when the operator performs an input operation to move the hands of the first progress display T7, the time shown by the first progress display T7 changes, and the work display changes to a work display corresponding to a progress other than the first progress.

Embodiment 8.
Next, a display control system 8 according to an eighth embodiment will be described with reference to Figs. 13 to 15. The display control system 8 according to the eighth embodiment differs from the display control system according to the first embodiment in the configuration of the display control device, but other configurations are similar. The same reference numerals are used to designate the same configurations as those in the first embodiment, and description thereof will be omitted.

Fig. 13 is a block diagram showing a schematic configuration of a display control system 8 according to embodiment 8. As shown in Fig. 13, the display control system 8 according to embodiment 8 includes a database DB1, a display control device 80, and a terminal 20, which are connected to each other so as to be able to communicate with each other. The display control device 80 is a device for controlling the content to be displayed on the display unit 21 of the terminal 20 based on input signals from the database DB1 and the terminal 20. As shown in Fig. 13, the display control device 80 includes a state information acquisition unit 84, a past information acquisition unit 85, a work information acquisition unit 81, a prediction unit 86, and operation information acquisition units 82 and 83.

The status information acquisition unit 84 acquires status information indicating that the status of the specific equipment has changed. For example, the status information acquisition unit 84 acquires information indicating that the status of the specific equipment has changed from a normal state as the third state to a non-normal state as the first state. Specifically, the status information acquisition unit 84 may acquire information indicating that the status of the specific equipment has changed based on a signal from the terminal 20, or may acquire the information from an external device (not shown).

The past information acquisition unit 85 acquires past information including work information acquired by the work information acquisition unit 81 in the past. For example, the past information acquisition unit 85 acquires past information from the database DB1, such as work information acquired by the work information acquisition unit 81 in the past, information on past changes in the state of a specific piece of equipment, information acquired in the past from the terminal 20, and external information on the equipment that may have affected the progress of the work. In addition, the past information acquisition unit 85 acquires work information acquired by the work information acquisition unit 81 in the past based on information acquired by the status information acquisition unit 84. For example, the past information acquisition unit 85 acquires work information acquired by the work information acquisition unit 81 in the past, triggered by a change in the state of a specific piece of equipment by the status information acquisition unit 84.

The work information acquisition unit 81 acquires work information related to work performed by a worker during a specific period until a specific piece of equipment changes from a first state to a second state, based on the information acquired by the state information acquisition unit 84 and the information acquired by the past information acquisition unit 85. For example, the work information acquisition unit 81 acquires work information by identifying a change in the state of a specific piece of equipment based on the information acquired by the state information acquisition unit 84, and extracting work information acquired by the work information acquisition unit 81 when there was a past change in state similar to the change in state. For example, possible methods for extracting past changes in state similar to a specific change in state include a method of using a trained model and a method of classifying state changes in advance.

The prediction unit 86 predicts the progress of work at a specific time after the time when a specific piece of equipment changes from a normal state to a non-normal state, based on the work information acquired by the work information acquisition unit 81. For example, the prediction unit 86 acquires information on the time required from the start to the end of each work process of the work information acquired by the work information acquisition unit 81 from database DB1, and predicts the progress of work at a specific time based on the acquired information. Note that the progress of work predicted by the prediction unit 86 may include the progress of work when the work is performed and the progress of work when the work is not performed, and the progress of work when the work is not performed may include the progress of other work that results from the work not being performed.

The operation information acquisition unit 82 acquires operation information indicating an input operation by an operator of the terminal 20. The function of the operation information acquisition unit 82 is similar to that of the operation information acquisition unit 12 according to the first embodiment, and therefore the description thereof is omitted.

The display control unit 83 causes the display unit 21 to display various information based on the information acquired by the status information acquisition unit 84, the operation information acquired by the operation information acquisition unit 12, the information acquired by the work information acquisition unit 11, and the result of the prediction by the prediction unit 86. For example, the display control unit 83 causes the display unit 21 to display the work information acquired by the work information acquisition unit 81 based on the information acquired by the status information acquisition unit 84, the operation information acquired by the operation information acquisition unit 82, and the result of the prediction by the prediction unit 86.

Next, referring to FIG. 14 and FIG. 15, the process performed by the display control device 80 to display various information on the display unit 21 will be described. FIG. 14 is a flowchart showing the process performed by the display control device 80 according to the eighth embodiment. As shown in FIG. 14, when the display control device 80 starts the process, first, the state information acquisition unit 84 acquires state information indicating that the state of a specific facility has changed (step ST21). For example, in this process, the state information acquisition unit 84 acquires information indicating that the specific facility has changed from a normal state to a non-normal state, as well as information indicating what the non-normal state is. Specifically, the state information acquisition unit 84 acquires information indicating that the operation of the railway has changed from a normal state, in which the operation of the railway is normal, to a non-normal state, in which the operation of the railway is disrupted, as well as information indicating what cause the non-normal state is based on.

When processing step ST21 is performed, the display control device 80 acquires past information including work information previously acquired by the work information acquisition unit 81 through the past information acquisition unit 85 (step ST22). When processing step ST22 is performed, the display control device 80 acquires work information based on the status information acquired by the status information acquisition unit 84 and the past information acquired by the past information acquisition unit 85 (step ST23). When processing step ST23 is performed, the display control device 80 causes the display unit 23 to display a first work display and a first progress display (step ST24, see Figure 5). When processing step ST24 is performed, the display control device 80 predicts the progress of the work at a specific time through the prediction unit 86 (step ST25).

When the process of step ST25 is performed, the display control device 80 judges whether or not an input operation to switch the work display displayed on the display unit 21 has been performed (step ST13). In this process, the display control device 80 judges whether or not an input operation to switch from the first work display S1 corresponding to the first progress displayed on the display unit 21 to the second work display corresponding to the second progress has been performed by the operator of the terminal 20. Note that the display control device 80 may be configured to perform a process (step ST27) to predict the impact of the work progress on other work and equipment by the prediction unit 86 after performing the process of step ST24 and before performing the process of step ST13. In the process of step ST13, if an input operation to switch the work display displayed on the display unit 21 has been performed (YES in step ST13), the display control device 80 causes the display unit 21 to display the second work display S2 and the second progress display T8 instead of the first work display S1 and the first progress display T1 (step ST26).

15 is a diagram showing the second task display S2 and the second progress display T8 that the display control unit 83 in the eighth embodiment causes the display unit 21 to display. In FIG. 15, the slider unit T13 is located at a position on the axis unit T11 that indicates the current time. For example, in step ST13, when an input operation is performed to switch from the first task display S1 corresponding to the first progress displayed on the display unit 21 to a task display corresponding to the task progress at a specific time after the current time, the display control unit 83 causes the display unit 21 to display the second task display S2 and the second progress display T8, which are task displays corresponding to the second progress of the task at a specific time after the current time, based on the prediction result by the prediction unit 86. For example, in step ST13, the input operation for switching from the first work display S1 corresponding to the first progress displayed on the display unit 21 to the second work display S2 corresponding to the second progress of the work at a specific time after the current time is an input operation for moving the cursor C1 in a dragging manner in a direction along the axis portion T11 (direction D1 shown in Figure 15) by operating the input unit 22.

For example, the second progress display T8 has a specific time display T18 that is arranged at a position on the axis T11 that indicates a specific time after the current time and indicates the specific time. Also, for example, the portion on the axis T11 that indicates a time before the current time, the portion that indicates the time between the current time and the specific time, and the portion that indicates a time after the specific time are displayed in different ways. Specifically, the portion on the axis T11 that indicates a time before the current time, the portion that indicates the time between the current time and the specific time, and the portion that indicates a time after the specific time are displayed in different colors. This allows the display control device 80 to indicate that the work display displayed on the display unit 21 is a work display that corresponds to a time after the current time, making it possible for the worker to easily obtain work information according to the progress of the work.

Note that, in step ST13, if there is an input operation to switch from the first work display S1 corresponding to the first progress displayed on the display unit 21 to a work display corresponding to the work progress at a specific time prior to the current time, the processing is similar to the processing in which the display control device 10 in embodiment 1 causes the display unit 21 to display the second work display and the second progress display, and therefore a description thereof will be omitted. If there is no input operation to switch the work display displayed on the display unit 21 in step ST13 (NO in step ST13), and if the processing of step ST26 has been performed, the display control device 80 terminates the processing.

In addition, the display indicating that the work display displayed on the display unit 21 is a work display corresponding to a time later than the current time is not limited to the above-mentioned, but may be the display shown in embodiments 9 and 10 described below.

Embodiment 9.
Next, a display control system according to a ninth embodiment will be described with reference to Fig. 16. The display control system according to the embodiment is different from the display control system according to the eighth embodiment in that the display indicating that the work display displayed on the display unit 21 is a work display corresponding to a time later than the current time is different, but the other configurations are the same, and the same reference numerals are used to designate the same configurations as those in the eighth embodiment, and description thereof will be omitted.

Figure 16 is a diagram showing the second work display and the second progress display that the display control unit in embodiment 9 causes to be displayed on the display unit. As shown in Figure 16, the display control unit in embodiment 9 causes the display unit 21 to display, together with the second work display S2, the second progress display T8 and a prediction display T9 indicating that the displayed work display is a predicted work display corresponding to a time later than the current time. For example, the prediction display T9 is composed of the words "Predicted information being displayed." This allows the display control device in embodiment 9 to more clearly indicate that the work display displayed on the display unit 21 is a work display corresponding to a time later than the current time, making it possible for the worker to easily obtain work information according to the progress of the work.

Embodiment 10.
Next, a display control system according to a tenth embodiment will be described with reference to Fig. 17. The display control system according to the tenth embodiment is different from the display control system according to the eighth embodiment in that the display indicating that the work display displayed on the display unit 21 is a work display corresponding to a time later than the current time is different, but the other configurations are the same, and the same reference numerals are used to designate the same configurations as those in the eighth embodiment, and description thereof will be omitted.

Figure 17 is a diagram showing the second work display and the second progress display that the display control unit according to embodiment 10 causes the display unit to display. As shown in Figure 17, the display control unit according to embodiment 10 causes the display unit 21 to display, together with the second work display S2, the second progress display T8 and a predicted display T10 indicating that the displayed work display is a predicted work display corresponding to a time later than the current time. For example, the predicted display T10 is configured by a frame that surrounds the area of the display unit 21 in which the second work display S2 and the second progress display T8 are displayed. This allows the display control device according to embodiment 10 to more clearly indicate that the work display displayed on the display unit 21 is a work display corresponding to a time later than the current time, making it possible for the worker to easily obtain work information according to the progress of the work.

The display indicating that the work display displayed on the display unit 21 corresponds to a time later than the current time is not limited to the above, and may be, for example, a display in which the background color of the area of the display unit 21 in which the second work display S2 and the second progress display T8 are displayed is a different color from that in the case where the work display displayed on the display unit 21 corresponds to a time later than the current time, a display in which the text color is a different color from that in the case where the work display displayed on the display unit 21 corresponds to a time later than the current time, or a combination of the above-mentioned displays.

Embodiment 11.
Next, a display control system 110 according to an eleventh embodiment will be described with reference to Figs. 18 to 22. The display control system according to the embodiment is different from the display control system according to the eighth embodiment in that the display unit 21 displays displays other than the work display and the progress display, but the other configurations are similar. Therefore, the same reference numerals are used to denote the same configurations as those in the eighth embodiment, and the description thereof will be omitted.

18 is a block diagram showing a schematic configuration of a display control system 110 according to embodiment 11. As shown in FIG. 18, the display control system 110 according to embodiment 11 includes a database DB1, a display control device 111, and a terminal 20, which are connected to each other so as to be able to communicate with each other. The display control device 111 is a device for controlling the content to be displayed on the display unit 21 of the terminal 20 based on input signals from the database DB1 and the terminal 20. As shown in FIG. 18, the display control device 111 includes a state information acquisition unit 84, a past information acquisition unit 85, an external information acquisition unit 117, a map information acquisition unit 118, a work information acquisition unit 81, a prediction unit 86, an operation information acquisition unit 82, and a display control unit 83.

The external information acquisition unit 117 acquires external information, which is information outside the facility that affects the progress of the worker's work. For example, if the facility is a railway, an increase in the number of railway passengers compared to normal times may affect the operation of the railway, and therefore affect the progress of the worker's work in a specific period. For this reason, for example, information about an event in the surrounding area where there is a possibility that the number of railway passengers will increase compared to normal times can be said to be external information that affects the progress of the worker's work. In addition, other external information that affects the progress of the worker's work includes, for example, information indicating the location of an emergency vehicle, information about the operation status of other public transportation for substitute transportation, information indicating the number of railway passengers, and traffic information on roads in the surrounding area. The external information acquisition unit 117 acquires external information from the database DB1, the terminal 20, and an external device not shown.

The map information acquisition unit 118 acquires map information of the surrounding area of the facility. For example, the map information acquisition unit 118 acquires information on roads, railway lines, buildings, etc. in the surrounding area as map information, and acquires external information from the database DB1, the terminal 20, and an external device not shown.

The information output unit 119 outputs information to an external device (not shown). For example, the information output unit 119 outputs to the external device work information, information on the progress of the work at the current time, information on the predicted results of the progress of the work at a time after the current time, information acquired from the database DB1 and the terminal 20, etc. The information output unit may be provided in a terminal that is communicatively connected to the display control device.

The display control unit 83 in embodiment 11 causes the display unit 21 to display map information, past information, external information, status information, work information, and information indicating the progress of work acquired by the display control device 111.

Next, referring to Figures 19 to 23, the processing performed by the display control device 111 to display various information on the display unit 21 will be described. Figure 19 is a flowchart showing the processing performed by the display control device 111 according to embodiment 11. As shown in Figure 19, when the display control device 111 starts processing, it first acquires status information by the status information acquisition unit 84 (step ST31), acquires past information by the past information acquisition unit 85 (step ST32), acquires external information by the external information acquisition unit 117 (step ST33), and acquires map information by the map information acquisition unit 118 (step ST34).

After performing the processing of step ST34, the display control device 111 acquires work information based on the status information acquired by the status information acquisition unit 84 and the past information acquired by the past information acquisition unit 85 (step ST35). The details of the processing of step ST35 are similar to the processing of step ST23 of the processing performed by the display control device 80 in embodiment 8, and therefore will not be described again. After performing the processing of step ST35, the display control device 111 displays the acquired map information, external information, status information, first work information, and first progress information on the display unit 21 (step ST36), and predicts the progress of the work at a specific time by the prediction unit 86 (step ST25).

20 is a diagram showing information including work information that the display control device 111 according to embodiment 11 displays on the display unit 21 when the specific facility is a railway. As shown in FIG. 20, for example, the information displayed on the display unit 21 includes map information M1, external information E1, G1, G2, BS1, status information J1, J2, TR1, first work display S1, and first progress display. For example, the map information M1 includes road information RD1, railway line information RW1 as a transportation facility related to the facility, station layout information ST1, and bus line information BL1 as a transportation facility related to the facility. Also, for example, the external information E1 is information indicating the position of an emergency vehicle, the external information G1 is information for identifying the emergency vehicle and information indicating the predicted time until the emergency vehicle reaches the station that is the destination, the external information G2 is information regarding the presence or absence of traffic congestion on roads in the surrounding area, and the external information BS1 is information indicating the positions of buses in the vicinity.

For example, the status information J1 and J2 is information indicating the state of railway operations. Specifically, when there is a disruption in operations, it is information indicating the cause of the disruption in operations and the location related to the cause. Note that the status information may also include information external to the facility. In this way, the display control unit 83 may be configured to display map information M1 on the display unit 21 together with the first work display S1 and the second work display S2.

Furthermore, the display control device 111 according to embodiment 11 causes the display unit 21 to display a past information search display S3 and a station information display S4. The past information search display S3 is a user interface for displaying past information on the display unit 21. The station information display S4 is a user interface for displaying information relating to the details of external information or status information on the display unit 21. For example, when an input operation is performed by the operator to select the station information display S4, the display control device 111 causes the display unit 21 to display information relating to the details of external information or status information. Specifically, when an input operation is performed by the operator to select the station information display S4, the display control device 111 causes the display unit 21 to display information relating to the details of external information or status information instead of work information.

21 is a diagram showing information including station information that the display control device 111 according to the eleventh embodiment displays on the display unit 21. As shown in FIG. 20, for example, the station information includes route information S5 showing a route map and operation information S6 showing the operation status at each station on the route map. In this way, the display control unit 83 may be configured to display the route information S6 and operation information S6 on the display unit 21 together with the first work display S1 and the second work display S2. Also, when the display control unit 83 is configured in this way, the map information acquisition unit 118 constitutes a route information acquisition unit that acquires route information of the transportation facility related to the facility. Also, for example, the display control device 111 may display a user interface for outputting information to the outside on the display unit 21. As a user interface for outputting information to the outside, for example, a button S9 for arranging personnel for support for a specific station, etc., and other buttons for arranging emergency vehicles, etc. are conceivable. For example, when an input operation for selecting the button S9 is performed by the operator, the display control device 111 outputs information requesting support to a specific station, etc. by the information output unit 119. In addition, when station information is displayed on the display unit 21 instead of work information, the display control device 111 displays a work information display button S7, which is a user interface for displaying work information on the display unit 21 instead of station information.

After performing the processing of step ST25, the display control device 111 determines whether or not an input operation has been performed to switch the work display displayed on the display unit 21 (step ST13). In the processing of step ST13, if an input operation has been performed to switch the work display displayed on the display unit 21 (YES in step ST13), the display control device 111 causes the display unit 21 to display the second work display and the second progress display instead of the first work display S1 and the first progress display T1 (step ST26). The details of the processing of steps ST13 and ST26 are similar to the processing of steps ST13 and ST26 performed by the display control device 80 according to embodiment 8, and therefore will not be described.

If there is no input operation to switch the work display displayed on the display unit 21 in step ST13 (NO in step ST13), and if the processing of step ST26 has been performed, the display control device 111 determines whether or not there has been an input operation to display past information (step ST37). For example, an input operation to display past information is an input operation to select the past information search display S3, which is the user interface shown in Figures 20 and 21. If there has been an input operation to display past information (YES in step ST37), the display control device 111 causes the display unit 21 to display the past information acquired by the past information acquisition unit 85 (step ST38).

22 is a diagram showing a list of past information that the display control device according to embodiment 11 displays on the display unit. As shown in FIG. 22, for example, in the process of step ST37, when there is an input operation to display past information, the display control device 111 displays one or more lists of past information acquired by the past information acquisition unit 85 on the display unit 21. Also, for example, when the display control device 111 displays one or more lists of past information on the display unit 21, the display control device 111 extracts one or more pieces of past information from the multiple pieces of past information acquired by the past information acquisition unit 85 based on one or both of the information acquired by the state information acquisition unit 84 and the input operation from the terminal 20, and displays the search results on the display unit 21. In other words, when the display control device 111 displays one or more lists of past information on the display unit 21, the display control device 111 searches for one or more pieces of past information from the multiple pieces of past information acquired by the past information acquisition unit 85 based on one or both of the information acquired by the state information acquisition unit 84 and the input operation from the terminal 20, and displays the search results on the display unit 21. When a list of one or more pieces of past information is displayed on the display unit 21 and the operator performs an input operation to select a specific piece of past information, the display control device 111 causes the display unit 21 to display details of the specific piece of past information.

Figure 23 is a diagram showing specific past information that the display control device 111 in embodiment 11 causes the display unit 21 to display. As shown in Figure 23, the display control device 111 causes the display unit 21 to display a first past work display S1 and a first past progress display T1 corresponding to the specific past information. Note that the processing performed when an input operation to switch the work display is performed while the first past work display S1 and the first past progress display T1 are displayed on the display unit 21 is similar to the processing performed in embodiments 1 to 10, and therefore will not be described here.

Furthermore, when displaying the past first work display S1 and the past first progress display T1, the display control device 111 may be configured to cause the display unit 21 to also display a display indicating that the work information does not relate to the current equipment status. Specifically, when displaying the past first work display S1 and the past first progress display T1, the display control device 111 causes the display unit 21 to also display information relating to the date and time and status information corresponding to the past information. For example, the information relating to the status information is a display indicating the content of the non-normal status related to the past information, specifically, a display of "overhead line fault" as shown in FIG. 23.

The display indicating that the work information does not relate to the current equipment status is not limited to the above, and various displays are possible, such as using a background color and text color different from those used when work information relating to the current equipment status is displayed, displaying a frame surrounding the area on display unit 21 where the work information and progress information are displayed, or displaying the words "past information" in text on display unit 21. If the processing of step ST38 has been performed, or if, in the processing of step ST37, there has been no input operation to cause display unit 21 to display past information (NO in step ST37), display control device 111 ends the processing.

In addition, this disclosure allows for free combinations of the embodiments, or modifications to any of the components of each embodiment, or the omission of any of the components in each embodiment.

The display control device disclosed herein can be used, for example, to improve the work efficiency of a worker by displaying information indicating the content of the work on a display unit while the worker is performing the work.
