Description

[Technical Field]

[0001] The present invention relates to a work support system and a work support method that display at least work information on a display unit of a mobile terminal carried by a worker working at a work site. [Background technology]

[0002] Conventionally, daily inspections and routine work performed by workers at steel mills and other factories involve printing out work procedures with checklists on paper, and workers then check the checklists on the paper. However, because a paper checklist would be enormous if it included every detailed description of all work procedures, some of the information had to be simplified. Also, it was not clear at a glance how much of the work had been completed, which could lead to workers skipping tasks or making mistakes, which could lead to serious accidents. To solve the problems caused by paper checklists, a work support system has been proposed in the past, as shown in Patent Document 1, for example. The work support system shown in Patent Document 1 supports workers using a wearable communication terminal that can be worn by the worker and a communication terminal device carried by the worker. In this work support system, a reception unit of the communication terminal device receives information related to work progress from the worker. A CPU of the communication terminal device obtains work procedure information, which is information related to work procedures, from a work database in accordance with the received information, and controls the communication I / F of the communication terminal device to transmit the information to the wearable communication terminal. In the wearable communication terminal, a control unit displays the received work procedure information on an output device so that the worker can visually confirm it.

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-114111 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the work support system disclosed in Patent Document 1 has the following problems. That is, in the case of the work support system shown in Patent Document 1, the output device of the wearable communication terminal displays the Nth work procedure information so that it can be seen by the worker, and after the Nth work is completed, the N+1th work procedure information is displayed. However, in this work support system, only the process in progress is displayed on the output device of the wearable communication terminal, and the overall picture of the work process (in addition to the process in progress, completed processes, and future processes) cannot be recognized, resulting in problems with workability.

[0005] Therefore, the present invention has been made to solve these conventional problems, and its purpose is to provide a work support system and work support method that improves workability by preventing workers from making mistakes in the work process, allowing co-workers to understand the work status even remotely, and allowing workers to visually see the overall picture of the work process, including the process they are currently working on, on a mobile terminal. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, one aspect of the present invention provides a work support system that displays at least work information on a display unit of a mobile device carried by a worker, and the work information can be divided into a plurality of work groups on a management PC, and a plurality of work procedures and work contents for each work procedure can be set for each work group, and a list of the plurality of work groups and a plurality of work procedures and work contents belonging to a work group currently being worked on among the plurality of work groups are displayed on the display unit, along with the work status. Another aspect of the present invention is a work support method that displays at least work information on a display unit of a mobile device carried by a worker, and is characterized in that the work information is divided into a plurality of work groups on a management PC, and a plurality of work procedures and work contents for each work procedure are set for each work group, and a list of the plurality of work groups and a plurality of work procedures and work contents that belong to a work group currently being worked on are displayed on the display unit, along with the work status. [Effects of the Invention]

[0007] The work support system and work support method according to the present invention can improve workability by preventing workers from making mistakes in the work process, allowing co-workers to understand the status of the work even remotely, and allowing workers to visually see the overall picture of the work process, including the process they are currently working on, on a mobile device.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments shown below are examples of devices and methods for embodying the technical concept of the present invention, and the technical concept of the present invention is not limited to the following embodiments in terms of the materials, shapes, structures, arrangements, etc. of the components. In addition, the drawings are schematic, and therefore it should be noted that the relationship between thickness and planar dimensions, ratios, etc. may differ from the actual relationship, and the drawings may also contain parts where the relationship and ratio of dimensions differ from each other. FIG. 1 shows an example of the configuration of a work support system according to one embodiment of the present invention. The work support system 10 shown in FIG. 1 includes a management PC 20, a server 30, and a plurality of mobile terminals 50A, 50B, . . . , 50N.

[0010] The management PC 20 is a computer system having a processing function for generating work information 60 (see FIGS. 2 and 3) for each type of daily inspection and inspection work in a factory or the like. Here, the work information 60 is created by the administrator by inputting predetermined information into, for example, an electronic file in a predetermined format (such as Excel) on the management PC 20. The input work information 60 includes work group information 61, work procedure information 62, and work record information 63, as shown in Figures 2 and 3. The work group information 61 is used to set which work belongs to which work group when a series of work tasks are grouped into multiple work groups (in the example shown in FIG. 2, there are three work groups A, B, and C, but there may be more). For example, in the work group information 61 shown in FIG. 2, advance preparation work is set to work group A, first equipment inspection work is set to work group B, and second inspection work is set to work group C. As shown in FIG. 2, in the work group information 61, a work name can be set for each of the work groups A, B, and C.

[0011] As shown in FIG. 2, the work procedure information 62 includes the work order, work content details, and worker assignment information. The order of work is automatically ranked, for example, from the work steps listed in the top rows of Excel to the work steps listed in the bottom rows (in the example shown in Figure 2, there are seven work steps, 1, 2, ..., 7, but there may be more or fewer). However, it is possible to set a flag indicating out of order for some work steps (any of work steps 1, 2, ..., 7) and work steps with the flag set to out of order will have the same order. In the example shown in Figure 2, the flag is set to out of order for work steps 4 and 5, and work steps 4 and 5 with the flag set to out of order will have the same order.

[0012] In addition, the details of the work content to be performed in each work procedure can be set in the work content details. In the example shown in FIG. 2, "Perform..." is set as the work content A1 to be performed in work procedure 1. "Perform..." is set as the work content A2 to be performed in work procedure 2. "Open the first valve" is set as the work content B3 to be performed in work procedure 3. "Open the second valve" is set as the work content B4 to be performed in work procedure 4. "Open the third valve" is set as the work content B5 to be performed in work procedure 5. "Measure the first hydraulic temperature" is set as the work content C6 to be performed in work procedure 6. "Measure the second hydraulic temperature" is set as the work content C7 to be performed in work procedure 7. The details of the work content can be input using text, images, videos, and PDFs.

[0013] Furthermore, the worker assignment information specifies who will perform which task among multiple work steps, especially when work is performed by multiple people. Workers are assigned to each work step according to the efficiency and difficulty of the work. This assignment does not assign the names of individuals who will actually perform the work, but is set using symbols such as worker a, worker b, worker c (leader class), ..., worker n. For example, if a series of work steps includes work steps to be performed at two different sites, worker a can be assigned to the work steps performed at one site, and worker b can be assigned to the work steps performed at the other site. It is also possible to assign multiple workers to one work step. In the example shown in Figure 2, worker b is assigned to the work of work step 1, worker b to the work of work step 2, and worker a to the work of work step 3. In addition, worker a is assigned to the work of work procedure 4, worker b to the work of work procedure 5, worker a and worker b to the work of work procedure 6, and worker a and worker b to the work of work procedure 7.

[0014] Furthermore, in the work record information 63, when a record of whether or not the work content of each work procedure included in the work procedure information 62 has been performed is requested, an input mode for the record is set. Examples of the input mode for the record include switch button (e.g., open / close icon) input, numerical input of measurement values ​​(measured values ​​such as temperature and pressure), reading a QR code (registered trademark), text input, time input (starting and stopping a timer), photographed image registration, and handwritten input on an attached diagram. In the example shown in FIG. 3 , switch button (open / close icon) input is set as the input for recording whether or not work contents B3, B4, and B5 of work procedures 3, 4, and 5 have been performed. Furthermore, numerical input of measured temperature values ​​is set as the input for recording whether or not work contents C6 and C7 of work procedures 6 and 7 have been performed. When the work record information 63 is set, as described below, unless input is made using the input mode set in each mobile terminal 50A, 50B, . . . , 50N, the work completion condition is not met, and each worker a, b, . . . , n cannot perform the work completion action. When entering measurement values ​​or time, both upper and lower limits can be set, or either one of the upper and lower limits can be set. In this case, if the entered measurement value or time is outside the range of the set upper and lower limits, the task completion condition can be set to be invalid.

[0015] As shown in FIG. 1, the management PC 20 is connected to the server 30 by wire or wirelessly, and work information 60 created by the management PC is stored in the server 30. 1, the server 30 is communicably connected to a plurality of mobile terminals 50A, 50B, . . . , 50N via a network 40. The network 40 is, for example, a WAN (Wide Area Network) such as the Internet. Furthermore, with respect to the multiple mobile terminals 50A, 50B, ..., 50N, as shown in Figure 1, a first worker a carries mobile terminal 50A, a second worker b carries mobile terminal 50B, ..., and an nth worker n carries mobile terminal 50N.

[0016] Each of the mobile terminals 50A, 50B, ..., 50N is a mobile terminal such as a smartphone, a notebook computer, or a tablet terminal, and includes a communication unit 51, a control unit 52, and a display unit 53. Each of the mobile terminals 50A, 50B, ..., 50N is a computer with a processing function, and executes display functions and the like in software according to commands of various dedicated computer programs pre-stored in hardware. The communication unit 51 of each of the mobile terminals 50A, 50B, . . . , 50N is connected to the network 40 so as to be able to communicate with each other. Furthermore, the control unit 52 of each of the mobile terminals 50A, 50B, ..., 50N can transmit and receive information to and from the server 30 via the communication unit 51 and the network 40. The control unit 52 then acquires information such as work information 60 stored in the server 30 from the server 30, and displays an image based on the acquired information on the display unit 53. The control unit 52 also controls the input of information from icons and the like displayed on the display unit 53, and activates or deactivates the icons and the like.

[0017] The display unit 53 displays an image output from the control unit 52. The display unit 53 sends information input from an icon or the like displayed on the display unit 53 to the control unit 52. The control unit 52 stores the information input from the display unit 53 in the server 30 via the communication unit 51. Next, taking the case where worker A, who is worker a, and worker B, who is worker b, work together as an example, the flow from various settings to work completion will be described with reference to Figures 4 to 10, assuming that worker A has mobile terminal 50A and worker B has mobile terminal 50B. Workers A and B work together on a factory inspection task based on work information created by management PC 20 shown in Figures 2 and 3.

[0018] First, before starting work, worker A or B accesses server 30 from mobile terminal 50A or 50B owned by the worker A or B to access specific information. As a result, the control unit 52 displays the login screen shown in Fig. 4 on the display unit 53 of mobile terminal 50A or 50B. Login to the work support system 10 is managed by ID and password, and worker A or B logs in by entering their own ID in ID input field 71 and their password in password input field 72 on the login screen displayed on the display unit 53 of their own mobile terminal 50A or 50B. When logging in, Worker A or B can select a mode, and can choose between work mode and reference mode. Work mode is used during actual work, and reference mode is used when referring to work information 60 created by management PC 20. Worker A or B logs in in work mode in the mode selection field 73 on the login screen displayed on their own mobile terminal 50A or 50B, and therefore selects work mode and logs in using login 74 when working on site.

[0019] When Worker A or B logs in using their own mobile terminal 50A or 50B, the control unit 52 displays, for example, a work information selection screen shown in FIG. 5 on the display unit 53 of the mobile terminal 50A or 50B. In the example shown in FIG. 5, design document confirmation work 81a, pre-confirmation work 81b, factory inspection work 81c, valve work 81d, and line inspection work 81e are selectable as work information on the display unit 53 of the mobile terminal 50A or 50B, and since factory inspection work will be performed in this example, Worker A or B clicks on factory inspection work 81c. When selecting work information, it is also possible to search for work information by entering a keyword in the keyword input field 82.

[0020] When Worker A or B selects task information on their own mobile terminal 50A or 50B, the control unit 52 displays, for example, the task start information input screen shown in FIG. 6 on the display unit 53 of the mobile terminal 50A or 50B. As described above, the task information 60 stored in the server 30 from the management PC 20 includes worker assignment information, and the actual task is set as workers a, b, ..., n. In this example, Worker A or B sets "A" in the input field 92a for "Worker A" displayed on the display unit 53 of their own mobile terminal 50A or 50B, and sets "B" in the input field 92b for "Worker B." No one is set in the input fields for other workers (including the input field 92n for "Worker N"). At this time, the task title can be set in the task title input field 91. The previously entered information can be canceled by clicking the cancel icon 93, and the task can be started by clicking the start icon 94.

[0021] Worker A or B can start work by setting up workers a and b on their own mobile terminal 50A or 50B and clicking the start icon 94. As a result, a list of work groups A (preparatory work), B (first equipment inspection work), and C (second equipment inspection work) shown in FIG. 7 is displayed on the display unit 53 of the mobile terminal 50A or 50B by the control unit 52. By logging in to the system in addition to worker A or B who made the settings, worker B or A can also view the list of work groups A, B, and C shown in FIG. 7 on their own mobile terminal 50B or 50A. This is because the information set up from the mobile terminal 50A or 50B owned by worker A or B who made the settings is stored in the server 30 via the network 40.

[0022] The work screen of the work information 60 displayed on the display unit 53 of the mobile terminal 50A carried by the worker A will be described below with reference to FIGS. 8 to 10. FIG. As mentioned above, when worker A or B sets up workers a and b on their own mobile terminal 50A or 50B, a list of work groups A (preparatory work), B (first equipment inspection work), and C (second equipment inspection work) is displayed on the display unit 53 of the mobile terminal 50A or 50B by the control unit 52, as shown in Figure 7. On display unit 53 of mobile terminal 50A carried by worker A, initially only the work procedures and work contents of work group A can be viewed, and the work procedures and work contents of work group B cannot be viewed until the work of work group A is completed. Also, the work procedures and work contents of work group C cannot be viewed until the work of work group B is completed.

[0023] FIG. 8 shows an example of an image in which work group B is working after work group A has completed. Here, on the work screen displayed on the display unit 53 of the mobile terminal 50A held by Worker A shown in Figure 8, a list 101 of multiple work groups A, B, and C that make up the work information 60 is displayed by the control unit 52, along with a work status 102 showing multiple work procedures 3, 4, and 5 and work contents B3, B4, and B5 that belong to the currently working work group B among the multiple work groups A, B, and C. In Fig. 8, the left side of the screen displays a list 101 of multiple work groups, including the names of work groups A, B, and C (work group A is doing advance preparation work, work group B is doing the first equipment inspection work, and work group C is doing the second equipment inspection work) and their statuses (work group A is complete, work group B is working, and work group C is incomplete). Here, for work group B, which is working, the status is displayed as a fraction (0 / 3) with the total number of work steps 3, 4, and 5 (3) as the denominator and the number of completed work steps (0) as the numerator, so that the progress of the work can be confirmed.

[0024] Also, in Figure 8, multiple work procedures 3, 4, and 5 belonging to work group B, which is currently working, are displayed on the right side of the screen, and all work procedures belonging to work group B can be viewed by scrolling the screen. Here, for each work procedure 3, 4, or 5, the work number (i.e., the work order), work status 102, worker name 103, work content B3, B4, or B5, and work record column (display based on work record information) are displayed. The work status 102 displays "Completed," "In Progress," or "Incomplete." The work procedure displayed as "In Progress" is the next work procedure to be performed. In the example of FIG. 8, work procedure 3 is in progress, work procedure 4 is incomplete, and work procedure 5 is incomplete. In the work record column (display based on work record information), a switch button (open / close icon) 105a is displayed for each of work procedures 3, 4, or 5. Furthermore, the record item column 104 displays the work points, if any, set on the management PC for each work content B3, B4, or B5. Furthermore, the special notes column 106 registers notes, photos, and videos outside of the record items as special notes. Furthermore, the share icon 108 allows coworkers to view the memo, image, and video data by clicking it.

[0025] Furthermore, a work completion icon 107 is provided for each of the work procedures 3, 4, and 5, and by touching the work completion icon 107, the work status 102 of the work procedure 3, 4, or 5 is changed from in progress to completed. If a work record field exists, the work completion icon 107 is in an inactive state and disables touch operations until an entry is made in the work record field, and the control unit 52 controls input from the display unit 53 so that the work completion icon 107 is activated on the condition that an entry is made in the work record field. In other words, the work status 102 of each of the work procedures 3, 4, and 5 displayed on the display unit 53 is changed from an incomplete state to a completed state by performing a predetermined work completion operation for the work contents B3, B4, and B5 of each of the work procedures 3, 4, and 5.

[0026] Regarding activation of the work completion icon 107, specifically, in work procedure 3, after worker A has completed the work (opened the first valve), he clicks the switch button 105a, and if a clear condition has been set, the next work completion icon 107 is activated. Also, in work procedure 4, when the work status 102 is in work, worker A as worker A has completed the work (opened the second valve), he clicks the switch button 105a, and if a clear condition has been set, the next work completion icon 107 is activated. In work procedure 5, when the work status 102 is in work, worker B as worker B has completed the work (opened the second valve), he clicks the switch button 105a, and if a clear condition has been set, the next work completion icon 107 is activated.

[0027] A work procedure with an incomplete work status cannot be operated unless the work procedure set above it has been completed. In other words, when the work orders of a first work procedure and a second work procedure included in multiple work procedures belonging to work groups A, B, and C are set in this order in the administration PC 20, control is performed so that a predetermined work completion action cannot be performed on the second work procedure on the mobile terminal 50A or 50B unless the work status of the first work procedure is in the completed state. In the example shown in FIG. 8, the work orders of a first work procedure 3 and a second work procedure 4 included in multiple work procedures 3, 4, and 5 belonging to work group B are set in this order in the administration PC 20 (see FIG. 2). In this case, the control unit 52 controls input from the display unit 53 of the mobile terminal 50A held by Worker A (and the same applies to the mobile terminal 50B held by Worker B) so that a predetermined work completion action cannot be performed on the second work procedure 4 unless the work status 102 of the first work procedure 3 is in the completed state.

[0028] In addition, suppose that the administration PC 20 sets the work orders of the first work procedure, the second work procedure, and the third work procedure included in the multiple work procedures belonging to each of the work groups A, B, and C in this order, and the second work procedure and the third work procedure are set in random order. In this case, the mobile terminal 50A or 50B is controlled so that the predetermined work completion action cannot be performed for the second work procedure and the third work procedure unless the work status of the first work procedure is in a work-completed state, while the predetermined work completion action can be performed for both the second work procedure and the third work procedure if the work status of the first work procedure is in a work-completed state. In the example shown in FIG. 8, the administration PC 20 (see FIG. 2) sets the work orders of the first work procedure 3, the second work procedure 4, and the third work procedure 5 included in the multiple work procedures 3, 4, and 5 belonging to the work group B in this order, and the second work procedure 4 and the third work procedure 5 are set in random order. At this time, on the display unit 53 of the mobile terminal 50A held by Worker A (similar to the mobile terminal 50B held by Worker B), if the work status 102 of the first work procedure 3 is not in a work-completed state, the predetermined work completion action cannot be performed for the second work procedure 4 and the third work procedure 5. On the other hand, if the work status 102 of the first work procedure 3 is in a work-completed state (see FIG. 9), the control unit 52 controls the input from the display unit 53 so that the predetermined work completion action can be performed for both the second work procedure 4 and the third work procedure 5.

[0029] 9, however, as will be described later, the worker for the second work procedure 4 is set to A, and the worker for the third work procedure 5 is set to B, so the predetermined work completion action cannot be performed from the mobile terminal 50A held by worker A for the third work procedure 5. Also, since the worker for the second work procedure 4 is set to A, and the worker for the third work procedure 5 is set to B, the predetermined work completion action cannot be performed from the mobile terminal 50B held by worker B for the second work procedure 4. 8, when the work completion icon 107 for work procedure 3 is touched, the control unit 52 performs control so that the input information in the work record field and the work completion information for work procedure 3 are sent to the server 30 via the network 40. Then, when the input information in the work record field and the work completion information for work procedure 3 are sent, the work status of work procedure 3 becomes completed, and the work statuses of work procedures 4 and 5 become in progress, as shown in FIG.

[0030] Here, assume that the administrator PC 20 allows a worker to be specified for each work procedure, and the worker for a specific work procedure is set to a first worker. In this case, the administrator PC 20 controls the portable device held by the first worker so that a predetermined work completion action can be performed for the specific work procedure, while controlling the portable device held by a second worker different from the first worker so that the predetermined work completion action cannot be performed for the specific work procedure. In the example shown in FIG. 9, the administrator PC 20 (see FIG. 2) sets the worker for work procedure 4 to "A," so the control unit 52 controls input from the display unit 53 of the portable device 50A held by worker A so that the predetermined work completion action can be performed for work procedure 4 on the display unit 53. The control unit 52 also controls input from the display unit 53 of the portable device 50B held by worker B so that the predetermined work completion action cannot be performed for work procedure 4 on the display unit 53 of the portable device 50B held by worker B. On the display unit 53 of the portable device 50B held by worker B, work procedure 4 is grayed out and inactive, and worker B cannot operate work procedure 4. Furthermore, in the management PC 20 (see FIG. 2), the worker for work procedure 5 is set to B, so the control unit 52 controls input from the display unit 53 so that the predetermined work completion action can be performed for work procedure 5 on the display unit 53 of the mobile terminal 50B held by worker B. Also, the control unit 52 controls input from the display unit 53 so that the predetermined work completion action cannot be performed for work procedure 5 on the display unit 53 of the mobile terminal 50A held by worker A. All work procedures 5 are grayed out and inactivated on the display unit 53 of the mobile terminal 50A held by worker A, so that worker A cannot operate the work procedure 5.

[0031] 9, when the work completion icon 107 for work procedure 4 is touched by Person A on the condition that work procedure 4 is entered in the work record column, the control unit 52 performs control so that the input information in the work record column and the work completion information for work procedure 4 are sent to the server 30 via the network 40. Also, when the work completion icon 107 for work procedure 5 is touched by Person B on the condition that work procedure 5 is entered in the work record column, the control unit 52 performs control so that the input information in the work record column and the work completion information for work procedure 5 are sent to the server 30 via the network 40 and stored. Then, when the input information and work completion information in the work record column for work procedures 4 and 5 are sent, the status of work group B becomes completed, the status of work group C becomes in progress, the work status 102 of work procedure 6 belonging to work group C becomes in progress, and the work status 102 of work procedure 7 becomes incomplete, as shown in Figure 10.

[0032] As for the work record columns (display based on work record information) in work procedures 6 and 7, a column 105b for the measured value of the first hydraulic temperature is displayed in work procedure 6, and a column 105b for the measured value of the second hydraulic temperature is displayed in work procedure 7. In work procedure 6, before Worker A or B inputs a measured value into the column 105b for the measured value of the first hydraulic temperature, the work completion icon 107 is in an inactive state and touch operation is disabled. Then, if Worker A or B inputs a measured value into the column 105b for the measured value of the first hydraulic temperature and the input value does not satisfy 20°C≦input value≦50°C, the work completion icon 107 remains in an inactive state. On the other hand, if the input value of the measured value of the first hydraulic temperature satisfies 20°C≦input value≦50°C, the work completion icon 107 is activated and touch operation is enabled. Furthermore, in work procedure 7, before Worker A or Worker B inputs a measurement value into the measurement value field 105b for the second hydraulic temperature, the work complete icon 107 is in an inactive state and touch operation is disabled. Then, if Worker A or Worker B inputs a measurement value into the measurement value field 105b for the second hydraulic temperature and the input value does not satisfy 20°C≦input value≦50°C, the work complete icon 107 remains in an inactive state. On the other hand, if the input value of the measurement value of the second hydraulic temperature satisfies 20°C≦input value≦50°C, the work complete icon 107 is activated and touch operation is enabled.

[0033] Here, in the administration PC 20, it is possible to designate multiple workers as workers for a specific work procedure, and when the workers for the specific work procedure are set to a first worker and a second worker, control is performed so that the predetermined work completion action for the specific work procedure can be performed on the mobile terminals carried by the first worker and the second worker. In the example shown in Fig. 9, in the administration PC 20 (see Fig. 2), the workers for work procedures 6 and 7 are set to a first worker A and a second worker B, and the names of A and B are displayed in the worker name 103. In this case, the control unit 52 controls input from the display unit 53 so that the predetermined work completion action can be performed for work procedures 6 and 7 on the display unit 53 of each of the mobile terminals 50A and 50B carried by workers A and B.

[0034] In this case, the control unit 52 controls the input from the display unit 53 of the mobile terminal 50C, ..., 50N carried by a third worker c, ..., n who is different from the first worker A and the second worker B, so that the specified work completion action cannot be performed for work steps 6 and 7. When work procedures 6 and 7 belonging to work group C are all completed, the status of work group C becomes complete, and all work of work groups A, B, and C is completed. As a result, the input information in the work record fields and the work completion information for work procedures 1, 2, ..., 7 are sent to server 30 via network 40 and stored.

[0035] When logging in in work mode, only work procedures (work procedures 3, 4, and 5 in Figures 8 and 9, and work procedures 6 and 7 in Figure 10) belonging to the work group currently being worked on (work group B in Figures 8 and 9, and work group C in Figure 10) can be displayed on the right side of the work screen in Figures 8 to 10. Work procedures belonging to completed or incomplete work groups (work groups A and C in Figures 8 and 9, and work groups A and B in Figure 10) cannot be viewed. On the other hand, in reference mode, it is possible to view work procedures of any work group. After the work is completed, the management PC 20 can access the server 30 and output a work report based on the input information in the work record fields for the stored work procedures 1, 2, ..., 7 and the work completion information.

[0036] As described above, the work support system 10 according to this embodiment displays at least task information 60 on the display units 53 of the mobile devices 50A, 50B, . . . , 50N carried by the workers a, b, . . . n. In this work support system 10, the work information 60 can be divided into multiple task groups A, B, . . . C on the management PC 20. Multiple task procedures 1; 2, 3; 4; 5, 6; 7 and task contents A1; A2, B3; B4; B5, C6; C7 for each task procedure 1; 2, 3; 4; 5, 6; 7 can be set for each task group A, B, . . . Then, on the display units 53 of the mobile devices 50A, 50B, . . . , 50N, a list 101 of the multiple task groups A, B, . . . and multiple task procedures 3, 4, 5 and task contents B3, B4, B5 belonging to task group B, which is currently working among the multiple task groups A, B, . . . C, are displayed together with task statuses 102.

[0037] This allows workers a, b, . . . n to avoid making mistakes in the work process and allows co-workers to understand the work status even remotely. Also, it is possible to improve workability by allowing workers a, b, . . . n to visually check the overall picture of the work process, including the process they are currently working on, on the mobile terminals 50A, 50B, . . . , 50N. Furthermore, according to the work support system 10 of this embodiment, the administration PC 20 can set the work order for the multiple work procedures 1; 2, 3; 4; 5, 6; 7 belonging to each work group A, B, C. The work status 102 of each work procedure 1; 2, 3; 4; 5, 6; 7 displayed on the display unit 53 of the mobile terminal 50A, 50B,..., 50N is changed from an incomplete state to a completed state by performing a predetermined work completion operation on the work contents A1; A2, B3; B4; B5, C6; C7 of each work procedure 1; 2, 3; 4; 5, 6; 7. Furthermore, it is assumed that the work orders of the first work procedure 3 and the second work procedure 4 included in the multiple work procedures 1; 2, 3; 4; 5, 6; 7 belonging to each work group A, B, C are set in this order on the administration PC 20. In this case, the mobile terminals 50A, 50B, ..., 50N are controlled so that a predetermined work completion operation cannot be performed for the second work procedure 4 unless the work status 102 of the first work procedure 3 is in a work completion state.

[0038] As a result, when the work orders of the first work procedure 3 and the second work procedure 4 included in the multiple work procedures 1; 2, 3; 4; 5, 6; 7 belonging to each work group A, B, C are set in this order, the condition for performing the predetermined work completion action for the first work procedure 3 is that the predetermined work completion action has been performed for the first work procedure 3, and the first work procedure 3 and the second work procedure 4 can be performed reliably in order. This makes it possible to reliably avoid skipping work. Furthermore, according to the work support system 10 of this embodiment, the management PC 20 can set the work order of some of the multiple work procedures 1; 2, 3; 4; 5, 6; 7 in a random order. Furthermore, suppose that the management PC 20 sets the work order of the first work procedure 3, the second work procedure 4, and the third work procedure 5 included in the multiple work procedures 1; 2, 3; 4; 5, 6; 7 belonging to each work group A, B, and C in this order, and also sets the second work procedure 4 and the third work procedure 5 in a random order. In this case, the mobile terminals 50A, 50B,..., 50N are controlled so that, unless the work status 102 of the first work procedure is in a work-completed state, the mobile terminals 50A, 50B,..., 50N cannot perform a predetermined work completion operation for the second work procedure 4 and the third work procedure 5. However, if the work status 102 of the first work procedure 3 is in a work-completed state, the mobile terminals 50A, 50B,..., 50N can perform a predetermined work completion operation for both the second work procedure 4 and the third work procedure 5.

[0039] This allows work to be carried out efficiently by setting some of the multiple work procedures (1; 2, 3; 4; 5, 6; 7) in random order depending on the work content of the work procedure. Furthermore, when the first work procedure (3), the second work procedure (4), and the third work procedure (5) included in the multiple work procedures (1; 2, 3; 4; 5, 6; 7) are set in this order and the second work procedure (4) and the third work procedure (5) are set in random order, the predetermined work completion action for the first work procedure (3) must be performed before the predetermined work completion action for the second work procedure (4) and the third work procedure (5) can be performed in order. This ensures that the first work procedure (3), the second work procedure (4), and the third work procedure (5) can be performed in order. This reliably prevents work from being skipped.

[0040] Furthermore, according to the work assistance system of this embodiment, the work status 102 of each work procedure 1; 2, 3; 4; 5, 6; 7 displayed on the display unit 53 changes from an incomplete state to a completed state by performing a predetermined work completion action for the work content A1; A2, B3; B4; B5, C6; C7 of each work procedure 1; 2, 3; 4; 5, 6; 7. Furthermore, the same work information 60 can be displayed and shared on the display units 53 of each mobile device 50A, 50B, . . . 50N owned by multiple workers a, b, . . . n. Furthermore, the management PC 20 can specify workers a, b, . . . n for each work procedure 1; 2, 3; 4; 5, 6; 7. When the worker for a specific work procedure 4 is set as the first worker a, the mobile device 50A owned by the first worker a is controlled so that a predetermined work completion action can be performed for the specific work procedure 4. Furthermore, the mobile terminal 50B held by a second worker b different from the first worker a is controlled so that a predetermined task completion action cannot be performed for a specific task procedure 4.

[0041] This makes it possible to avoid operational mistakes caused by different workers. Furthermore, according to the work support system 10 of this embodiment, it is possible to designate multiple workers as workers for a specific work procedure in the management PC 20, and when the workers for a specific work procedure 6 are set to a first worker a and a second worker b, control is performed so that the mobile terminals 50A, 50B carried by the first worker a and the second worker b can perform a predetermined work completion action for the specific work procedure 6. In addition, control is performed so that the predetermined work completion action for the specific work procedure 6 cannot be performed on the mobile terminals 50C, . . . , 50N carried by third workers c, . . . , n different from the first worker a and the second worker b.

[0042] This makes it possible to avoid work errors that may occur when multiple workers are designated as workers for a specific work procedure, and workers other than the designated workers perform the specified work completion operations on their own mobile devices. Furthermore, according to the work support method of this embodiment, at least work information 60 is displayed on the display units 53 of mobile terminals 50A, 50B,...,50N carried by workers a, b,...,n. In this work support method, the management PC 20 divides the work information 60 into multiple work groups A, B, C, and sets multiple work procedures 1; 2, 3; 4; 5, 6; 7 and work contents A1; A2, B3; B4; B5, C6; C7 for each work procedure 1; 2, 3; 4; 5, 6; 7 for each work group A, B, C. Then, on the display units 53 of the mobile terminals 50A, 50B,...,50N, a list 101 of the multiple work groups A, B, C and multiple work procedures 3, 4, 5 and work contents B3, B4, B5 belonging to the currently working work group B among the multiple work groups A, B, C are displayed together with work statuses 102.

[0043] This allows workers a, b, . . . n to avoid making mistakes in the work process and allows co-workers to understand the work status even remotely. Also, it is possible to improve workability by allowing workers a, b, . . . n to visually check the overall picture of the work process, including the process they are currently working on, on the mobile terminals 50A, 50B, . . . , 50N. According to the work support method of this embodiment, the administration PC 20 sets a work order for multiple work procedures 1; 2, 3; 4; 5, 6; 7 belonging to each work group A, B, C. The work status 102 of each work procedure 1; 2, 3; 4; 5, 6; 7 displayed on the display 53 of the mobile terminals 50A, 50B, ..., 50N is changed from an incomplete state to a completed state by performing a predetermined work completion operation on the work contents A1; A2, B3; B4; B5, C6; C7 of each work procedure 1; 2, 3; 4; 5, 6; 7. The administration PC 20 also sets the work order for the first work procedure 3 and the second work procedure 4 included in the multiple work procedures 1; 2, 3; 4; 5, 6; 7 belonging to each work group A, B, C. In this case, the mobile terminals 50A, 50B, ..., 50N are controlled so that a predetermined work completion operation cannot be performed for the second work procedure 4 unless the work status 102 of the first work procedure 3 is in a work completion state.

[0044] As a result, when the work orders of the first work procedure 3 and the second work procedure 4 included in the multiple work procedures 1; 2, 3; 4; 5, 6; 7 belonging to each work group A, B, C are set in this order, the condition for performing the predetermined work completion action for the first work procedure 3 is that the predetermined work completion action for the second work procedure 4 has already been performed, and the first work procedure 3 and the second work procedure 4 can be performed reliably in order. This makes it possible to reliably avoid skipping work. Furthermore, according to the work support method of this embodiment, the management PC 20 sets the work order by randomly setting some of the multiple work procedures 1; 2, 3; 4; 5, 6; 7. Furthermore, the management PC 20 sets the work order of the first work procedure 3, the second work procedure 4, and the third work procedure 5 included in the multiple work procedures 1; 2, 3; 4; 5, 6; 7 belonging to each work group A, B, and C in this order, and also sets the second work procedure 4 and the third work procedure 5 in random order. In this case, the mobile terminals 50A, 50B,..., 50N are controlled so that, unless the work status 102 of the first work procedure is in a work-completed state, the mobile terminals 50A, 50B,..., 50N cannot perform a predetermined work completion operation for the second work procedure 4 and the third work procedure 5. However, if the work status 102 of the first work procedure 3 is in a work-completed state, the mobile terminals 50A, 50B,..., 50N can perform a predetermined work completion operation for both the second work procedure 4 and the third work procedure 5.

[0045] This allows work to be carried out efficiently by setting some of the multiple work procedures (1; 2, 3; 4; 5, 6; 7) in random order depending on the work content of the work procedure. Furthermore, when the work order of the first work procedure (3), the second work procedure (4), and the third work procedure (5) included in the multiple work procedures (1; 2, 3; 4; 5, 6; 7) is set in this order and the second work procedure (4) and the third work procedure (5) are set in random order, the predetermined work completion action for the first work procedure (3) must be performed before the predetermined work completion action for the second work procedure (4) and the third work procedure (5) can be performed in order, ensuring that the first work procedure (3), the second work procedure (4), and the third work procedure (5) can be performed in order. This reliably prevents work from being skipped.

[0046] Furthermore, according to the work support method of this embodiment, the work status 102 of each work procedure 1; 2, 3; 4; 5, 6; 7 displayed on the display unit 53 changes from an incomplete state to a completed state by performing a predetermined work completion action for the work content A1; A2, B3; B4; B5, C6; C7 of each work procedure 1; 2, 3; 4; 5, 6; 7. Furthermore, the same work information 60 can be displayed and shared on the display units 53 of each mobile terminal 50A, 50B, . . . , 50N owned by multiple workers a, b, . . . , n. Furthermore, the management PC 20 can specify workers a, b, . . . , n for each work procedure 1; 2, 3; 4; 5, 6; 7. When the worker for a specific work procedure 4 is set as a first worker a, the management PC 20 controls the mobile terminal 50A owned by the first worker a to perform a predetermined work completion action for the specific work procedure 4. Furthermore, the mobile terminal 50B held by a second worker b different from the first worker a is controlled so that a predetermined task completion action cannot be performed for a specific task procedure 4.

[0047] This makes it possible to avoid operational mistakes caused by different workers. Furthermore, according to the work support method of this embodiment, it is possible to designate multiple workers as workers for a specific work procedure in the management PC 20, and when the workers for specific work procedure 6 are set to a first worker a and a second worker b, control is performed so that the mobile terminals 50A, 50B carried by the first worker a and the second worker b can perform a predetermined work completion action for the specific work procedure 6. Furthermore, control is performed so that the predetermined work completion action for the specific work procedure 6 cannot be performed on the mobile terminals 50C, . . . , 50N carried by third workers c, . . . , n different from the first worker a and the second worker b.

[0048] This makes it possible to avoid work errors that may occur when multiple workers are designated as workers for a specific work procedure, and workers other than the designated workers perform the specified work completion operations on their own mobile devices. Next, a method for completing a task when photographed image registration is set as the input mode for recording whether the task content has been completed in the management PC 20 will be described with reference to Fig. 11. Fig. 11 shows an example of a task screen displayed on the display unit 53 of the mobile terminal 50A held by a specific worker A when photographed image registration is set as the input mode for recording whether the task content has been completed.

[0049] In this case, worker A clicks on the photo taking section 105g displayed on the display unit 53 of the mobile terminal 50A to activate the camera (not shown) of the mobile terminal 50A. Then, worker A takes a picture of the status of the valves at the site with the camera. This activates the work completion icon 107. Then, worker A clicks the work completion icon 107 to complete the work. On the other hand, if the valve status is not photographed, the work completion icon 107 remains inactivated. Furthermore, how to perform the task completion operation when handwritten input to an attached drawing is set as the input mode for recording whether the task content has been completed in the management PC 20 will be described with reference to Fig. 12. Fig. 12 shows an example of a task screen displayed on the display unit 53 of the mobile terminal 50A held by a specific worker A when handwritten input to an attached drawing is set as the input mode for recording whether the task content has been completed.

[0050] In this case, Worker A checks the checklist 105h (attached diagram) displayed on the display unit 53 of the mobile terminal 50A at the work site, clicks the edit icon 105i, and enters the necessary information in the checklist 105h. This activates the work completion icon 107. Then, Worker A clicks the work completion icon 107 to complete the work. On the other hand, if Worker A does not enter the necessary information in the checklist 105h, the work completion icon 107 remains inactivated. Although the embodiment of the present invention has been described above, the present invention is not limited to this and various modifications and improvements can be made.

[0051] For example, in the examples shown in Figures 7 to 10, the work groups are divided into three groups: work group A (preparatory work), B (first equipment inspection work), and C (second equipment inspection work), but the work groups may be divided into groups other than three. Furthermore, in the management PC 20, the work procedures are set to seven, namely, work procedures 1, 2, ..., 7, with work group A's work procedures set to 1 and 2, work group B's work procedures set to 3, 4, 5, and work group C's work procedures set to 6 and 7. However, it is not necessarily necessary to set the work procedures to seven work procedures. Furthermore, it is not necessarily necessary to set the work procedures for each work group in this way. Furthermore, the work content of each work procedure can also be set arbitrarily. [Explanation of symbols]
