Japanese Patent Laid-Open No. 06-162034 JP 2009-99100 A

  By the way, for example, in construction work (construction work) and maintenance work (maintenance work) of a power plant, improvement of work efficiency and shortening of a construction period are major issues. For this reason, the actual man-hour management of workers has become important. It is important to grasp the time required for direct work, and the ability of the worker can be evaluated by grasping the actual work number. By organizing, process management along the target process, work man-hours and work personnel can be predicted, and target management can be performed.

However, the actual number of actual man-hours so far is not based on strict time measurement, but based on the time related to the worker's labor, that is, the time when he went to work and the time when he left work. The time in the meantime included things other than the actual man-hours such as the time required for the worker to move to the work place, the preparation time before the start of the work, and the cleanup time after the work was completed.
Factors that have grasped the rough actual number of man-hours are that workers of various occupations move to the work area of each place in the power plant for the construction and maintenance work of the power plant. This is because the work in cooperation with the post-process was performed and it was difficult to measure the exact time.

For example, taking pipe installation work as an example, workers or work groups differ for each work procedure such as pipe member import work → groove alignment work → welding work → finishing work → weld inspection → painting work, In this work, time such as movement to the work place, preparation work, tidying work, and movement after work was also included, and the time measurement was not made.
In addition, it moves to move to the next work place, or the work is interrupted due to various factors and other work is started. For example, there were factors that made it difficult to distinguish between actual man-hours and preparation time and clean-up time in response to changes in work conditions, but the actual man-hours could be measured separately. There wasn't.
In power plant construction work and maintenance work, work instructions are issued for each work, but the actual man-hours for each work instruction cannot be measured. Furthermore, the competence evaluation by worker type and work group has not been achieved.

  The present invention solves the above-described conventional problems, and is capable of measuring the actual number of workers in plant construction work and maintenance work separately from preparation time, travel time, clean-up time, etc. An object is to provide a management system and a work management method.

In order to solve the above-mentioned problems, the present invention attaches in advance a product wireless identification tag for identifying a target device or target object of the construction in a plant facility construction work and maintenance work management method. In addition, at least entrance / exit detection means capable of communicating with the personal wireless identification tag held by the worker is installed at the entrance / exit of the work area of the construction,
Using a portable terminal having tag communication means, photographing means, display means, and input means capable of communicating with the product wireless identification tag and the personal wireless identification tag, identification information is obtained from the product wireless identification tag,
A first work step for inputting start or resumption of work and a second work step for inputting completion or interruption of work are displayed on the display means, and the object is displayed in the first work step and the second work step. While letting the operator photograph the work part of the object, obtain time information at the time of photographing as actual man-hour time information,
Time information when the personal wireless identification tag is detected by the entry / exit detection means is acquired as entry / exit time information, and based on the entry / exit time information and the time information of the actual man-hours, the actual man-hours and before and after It is characterized in that the preparation / tidy-up time is divided and measured.

According to the present invention, it is possible to determine the stay of each worker in the work area by the entry / exit detection means, and the worker's identification information is input to the portable terminal as the worker of the work during the stay time. When the actual man-hour time information of the first work step for inputting the start or restart of the work and the second work step for inputting the completion or interruption of the work is acquired, the entry / exit detection means Based on the acquired entry / exit time information of each worker and the actual man-hour time information, the actual man-hour and the preparation / clean-up time before and after that can be measured separately.
As a result, the actual number of man-hours for each work can be easily tabulated and distinguished from the previous preparation time and the subsequent cleaning time.

  According to the present invention, there is provided a work management system and a work management method capable of measuring the actual number of workers in plant construction work and maintenance work separately from preparation time, travel time, cleanup time, and the like. Can do.

<Work flow for creating work instructions>
Next, with reference to FIGS. 19 and 20, as necessary, with reference to FIGS. A flowchart of a control flow in which the unit 216 (see FIG. 2) assists the work of creating the work instruction sheet 60 will be described. FIG. 19 is a flowchart of a control flow for assisting the creation of the work instruction. Here, a case where a groove alignment work instruction 60 in piping work is created will be described as a specific example.
The operator first selects a work instruction creation function by the work instruction creation unit 216 of the office terminal 11. Here, description will be made on the assumption that the work instruction 60 (see FIG. 10) is created from the beginning.

  In step S11, the operator operates the input unit 23 (see FIG. 2) to accept an input for selecting the format (model) of the work instruction sheet 60 from the work instruction sheet DB 16K in the menu format. Then, the format of the accepted work instruction sheet 60 is displayed on the display unit 22 (see FIG. 2). And it will be in the input reception state of the work name, book number, etc. of step S12.

The operator selects a work name from the menu screen, for example, pipe groove alignment and groove inspection (abbreviated as “pipe FU” in FIG. 11 which means pipe groove alignment), and the work name field 61a ( 11), and the book number is entered while checking the work instruction document ID information column of the work procedure DB 16H (see FIG. 6).
The book numbers are automatically numbered by linking with work procedure items in the work procedure DB 16H. When the book numbers are matched with the groove alignment items in FIG. A book number obtained by adding 1 to a sequence number that already exists under the number classification is automatically generated and input to the book number column 61b.

Next, the operator selects the systematic name to display the menu selection screen of systematic name, for example, select the "turbine main steam", the systematic name abbreviation "MS (M ain S team)", systematic name field 61d, and enter the systematic name abbreviations column 61d _1, to display the search menu screen pipe working drawings, enter the piping construction drawing number from the pipe construction diagram DB included in the design diagram information DB16A (see FIG. 3). As a result of the input, in step S13, in response to the input of the system name and the piping construction drawing number, the piping construction drawing is searched from the piping construction drawing DB included in the design drawing information DB 16A. At this time, the piping construction figure number is input to the piping construction figure number column 61e of FIG.

And in step S14, the searched piping construction drawing is displayed on the display part 22, and the input of a welding line number, a work area number, and a line number is received. Specifically, as shown in FIG. 4 (a), the piping construction diagram includes area numbers and weld line numbers, so copy the text data of the corresponding area numbers and weld line numbers. , the area number column of the work instruction sheet 60 61 g, pasted to the welding line (the joint) number column 61f _1.
Also, when the corresponding weld line number in the piping construction diagram shown in FIG. 4 (a) is clicked, the weld detail data table shown in FIG. 4 (c) is displayed. The text data is copied and pasted in the line number column 61h. By these operations, the welding line number, work area number, and line number can be input easily and accurately.

  In step S15, both upstream and downstream piping information is transcribed from the piping construction drawing. As described above, since the welded portion detailed data table shown in FIG. 4C is displayed, the data in the columns from the spool number column to the wall thickness are copied and stored in the welded upstream / downstream piping data column 62. paste. Although not shown in FIG. 4C, an identifier is attached to the data, and the operation record column is automatically skipped and pasted to the corresponding column in the weld upstream / downstream piping data column 62. Is done. Incidentally, the data in the welding inspection presence / absence column of FIG. 4C is ignored and pasted in the welded portion upstream / downstream piping data column 62.

Next, in step S16, groove part information is transcribed from the piping construction drawing. In step S17, an input of an applicable measuring instrument name is received.
Specifically, link data not shown in the drawing is attached to the groove thickness dimension column and the groove shape column shown in FIG. When the background color is reversed and clicked, the groove portion information related to this field in the groove information DB included in the detailed construction information DB 16B is popped up, and “standard” in the groove data column 63A is displayed. ”,“ Minimum ”wall thickness data, data in the fields 63c, 63e, and 63g in the groove data column 63B, a groove shape abbreviation in the groove shape code column 64a in the groove shape diagram column 64, and a figure in the drawing column 64b information, column of the groove data column 63C 63i, 63k, data corresponding to the column of _{63n 1, 63n 4, 63n 7} , 63n 10, 63n 13 is displayed. Furthermore, the type corresponding to the application the instrument column 63p ₁ ~63p _5, the outer shape photo is displayed. Accordingly, the operator inputs the data in the corresponding fields of the groove data fields 63A, 63B, 63C by copying and pasting.
However, in step S17, “Applying Applicable Instrument Name Input Accepted” is displayed. However, in addition to the name of the measuring instrument, the model of the measuring instrument and the external photograph are also accepted.

In step S18, an input of a construction confirmation item is accepted. Corresponding to the work name entered in the work name column 61a, the contents of the construction work confirmation item are linked from the detailed construction information DB 16B so as to be searchable, and the construction time confirmation displayed on the display unit 22 is linked. Copy the contents of the item and paste it in the confirmation item column 65 during construction.
In step S19, a photo record at the time of completion of the previous process in the work instruction sheet 60 is searched based on the work procedure DB 16H and the work record DB 16M, and transferred to the photo column 66 at the time of completion (interruption) of the previous process, and a time information column 66b. Also post time information.

In step S20, the input of the construction team / worker is accepted. Specifically, the operator searches the work group information corresponding to the work group information column 70 from the construction group / worker DB 16L, and transcribes the information in the columns 70a to 70d. At this time, the name of the contractor, the name, and the qualification necessary for the work are displayed in the columns 70a to 70d. As link information not displayed, there are RFID tag information, personal ID information, and a qualified code. In step S21, an input of a target man-hour is accepted. Specifically, the operator retrieves and inputs the target man-hour corresponding to the work name input in step S12 from the construction man-hour DB 16N.
In step S22, the operator displays the entire work instruction sheet 60 and confirms the uninput data, and then checks whether or not the confirmation end operation has been performed (“end of the work instruction sheet confirming display?”). If the confirmation end operation has been performed (Yes), the process proceeds to step S23. If the confirmation end operation has not been performed (No), the operator moves the cursor to a non-input field or makes an error input. You can move the cursor to the field and continue the input.

In step S23, the input of the work instruction creator name is accepted. Specifically, this input is based on the personal ID information by reading the personal ID information of the RFID tag built in the personal ID card with a photograph attached to the chest of the operator with the RFID_R / W 24, for example. The name is searched from the personnel management DB 16D, and the name is entered in the issuer name field 71b (see FIG. 17).
In step S24, the draft of the created work instruction 60 is transferred to the investigator and approver. This transfer is performed by an electronic approval procedure linked with the mail system. In response to this, the investigator examines the draft of the work instruction 60 and the approver approves it. This is the same as in step S23. For example, the personal ID of the RFID tag built in the personal ID card with a photograph attached to his / her chest as the operator of the office terminal 11 (see FIG. 2) by the investigator or the approver. By reading the information with the RFID_R / W 24, the name is searched from the personnel management DB 16D based on the personal ID information, and the name is input to the investigator name field 71d and the approver name field 71f. Then, by performing an operation for making the investigation and approval OK, the date at the time of the operation is automatically input to the date / month fields 71c and 71e.

In step S25, it is checked whether the investigation and approval of the work instruction 60 has been completed.
If the investigation and approval of the work instruction 60 has been completed (Yes), the process proceeds to step S26, and if not (No), step S25 is repeated. In step S26, the completion of investigation and approval is notified to the work instruction creator. This can be automatically confirmed by receiving an e-mail to the drafter at the end of each procedure of investigation and approval, and returning the contents of the investigation and approval to the drafter's office terminal 11.
When the investigation and approval procedures are completed, the work instruction 60 is transferred to the drafter's office terminal 11 and, if there is a comment from the investigator or approver, it is officially issued. By officially issuing the work instruction 60, the date of issue is automatically entered in the date field 71b.
Further, the officially issued work instruction sheet 60 is registered in the work instruction sheet DB 16K and is also registered in the work procedure sheet DB 16H in conjunction with the work instruction sheet.
In the example of the work instruction 60 for pipe groove alignment, the book number (work instruction sheet) of the work instruction 60 is displayed in each column next to the local work procedure of “groove alignment” of item numbers 1-9 in FIG. ID information) and the line number in the line number field 61h (see FIG. 11) and the weld line number in the weld line (joint) number field 61f ₁ (see FIG. 11) in the product ID information field. Information in the work group information column 70 (see FIG. 16) is input in the personal ID information column, and the area number in the area number column 61g is input in the area ID information column.

  Thus, the procedure for issuing the new work instruction 60 is completed. The operator uploads the work instruction sheet 60 to the portable terminal 41 (see FIG. 2) to be held by the work group in charge of the contents of the work instruction sheet 60, and if necessary, the related design drawing information is transferred to the design drawing information DB 16A. Therefore, for example, a piping construction drawing of the work area is also uploaded to the portable terminal 41 to assist in confirming the piping to be worked.

If the work instruction 60 has already been issued and the work is interrupted for some reason and the work record is stored in the work record DB 16M in that state, the work instruction 60 is interrupted in step S116 of FIG. The work record itself is automatically updated to Rev. It is created as a work instruction sheet 60 (see FIG. 10) with a number increased by one. Specifically, data that has already been input as a work record is directly updated from the work record as Rev. The work record column that has been transferred to the numbered work instruction 60 is left blank, and the unrecorded work record column is left blank. After the previous process is completed (suspended), the data in the photo column 66 is deleted, and the work in the suspended work record is performed. Photo data and date / time information in the columns 68a and 68b of the photo column 68 at completion (interruption) are transferred to the columns 66a and 66b, and data in the photo column 67 at work start (resumption) and photo column 68 at work completion (interruption). Is deleted.
Also, the fields 73a and 73b (see FIG. 18) of the business record confirmation procedure field 73 are blanked.

  Then, if necessary, the data in the work group information column 70 is changed to change to a work group capable of working on the day.

<Work flow for creating work records>
Next, with reference to FIGS. 21 to 23, referring to FIGS. 1, 2, 5, 10, and 24 to 30, work recording is performed using the portable terminal 41 (see FIG. 2). A flowchart of a control flow in which the creation unit 243 (see FIG. 2) assists in creating the work instruction sheet 60 will be described. FIGS. 21 to 23 are flowcharts of a control flow for selecting a work instruction and assisting in inputting a work record.
First, workers 51 (see FIG. 1) constituting a work group enter the work area designated by the work instruction sheet 60 with the portable terminal 41. Therefore, the portable terminal 41 is activated and the function of the work record creation unit 243 is operated.
As a result, the number of work instructions 60 (see FIG. 10) stored in the storage unit 41f of the portable terminal 41 is displayed on the display unit 41b, so that book numbers, work names, work area numbers, and work that constitute work groups "Start work" or "Resume work" is displayed for the personal ID information of the person 51 or the like and the work instruction 60.

  Here, the display of “start work” or “restart work” is also an icon button, and the book number in the book number column 61b (see FIG. 11) of the work instruction 60 is Rev. In the case of 0, since this is the first work for the work instruction 60, the “Resume Work” display is gray, for example, so that the “Resume Work” icon button cannot be pressed. To display. Rev. attached to the book number of the work instruction 60 One or more Rev. In the case of the number, since it is a rework for the work instruction 60, the display of “Resume work” is clearly displayed and displayed so that the icon button can be pressed, and “Start work” is displayed. The display is, for example, gray so that the “work start” icon button cannot be pressed.

In step S31, a message “Please read your RFID tag” is displayed on the display unit 41b (see FIG. 2). At this time, an icon button of “end input of personal ID information” is also displayed.
In step S32, the RFID tags of the workers 51 including the work group head are read.
In step S33, the personal ID information read in step S32 is displayed on the display unit 41b. In step S34, it is checked whether or not the operator has pressed the icon button for ending the input of personal ID information using the RFID tag ("Press the input end button?"). If the “end of personal ID information input” icon button is pressed (Yes), the process proceeds to step S35, and if not pressed (No), steps S32 to S34 are repeated.

In step S36, for example, a group is identified based on the personal ID information of the team leader in the worker 51 or the like input in steps S32 to S34, and the corresponding work instruction 60 that the group is scheduled to work on is determined. And a message “Please select the work instruction you are responsible for” is displayed on the display unit 41b. Also at this time, the book number, work name, work area number, personal ID information of the workers 51 and the like constituting the work team, and “start work” or “restart work” for the work instruction 60 are displayed. . On this display screen, “return button” and “decision button” are displayed as icon buttons.
When the operator places the marker on the corresponding book number in the work instruction sheet 60 and presses the “OK” button, the work instruction sheet 60 is selected. In step S37, it is checked whether or not the work instruction sheet 60 has been selected ("select work instruction sheet?"). If the work instruction sheet 60 is selected (Yes), the process proceeds to step S38, and if not selected (No), the process returns to step S36.

In step S38, the selected work instruction 60 is displayed on the display unit 41b. In this display screen, “return button”, “decision button”, and “start button” or “resume button” are displayed as icon buttons.
The operator 51 confirms the displayed work instruction 60, and if it is correct, the operator presses the “decision button”, and if it is incorrect, presses the “return button”.
In step S39, it is checked whether the return button or the decision button has been pressed. If the “return button” is pressed, the process returns to step S36, and if the “decision button” is pressed, the process proceeds to step S40.

In step S40, the work instruction sheet 60 displayed in step S38 is displayed on a screen for creating a work record. That is, it is in a state of accepting input. In step S41, a message “Please read the RFID tag attached to the work target indicated by the work instruction and the work target part” is displayed on the display unit 41b.
In response to this, for example, the operator uses the RFID_R / W 41e to read the RFID tag 44 attached in the vicinity of the welded portion of the upstream and downstream pipes of the weld line number specified in the work instruction sheet 60. In step S42, the instructed RFID tag 44 is read and product identification information is displayed. The product identification information corresponding to the work instruction sheet 60 includes “206A-T32-W2Y” and “206A” stored in the two RFID tags 44 on the upstream and downstream sides of the field welding line labeled “W2Y” in FIG. -T33-W2Y "spool number and weld line number.

In step S43, it is checked whether the RFID tag 44 attached to the work target or the work target part is correct. This determination is in the work record creation unit 243, a data weld line (joint) number column 61f _1, the upstream and downstream sides of the data of the spool number column 62a, and product identification information read from the RFID tag 44, 44 This can be easily done by comparing
If not correct (No), the process proceeds to step S44 of FIG. 22 according to the connector (B), and if correct (Yes), the process proceeds to step S45 of FIG. 22 according to the connector (C).

In step S44, a message “Not a correct work target or work target part, please read the RFID tag again” is displayed on the display unit 41b. Thereafter, the process returns to step S42 in FIG. 21 according to the connector (D).
In step S45, a message “Please photograph the work target or work target part designated by the work instruction sheet and press the start button or the resume button” is displayed on the display unit 41b. Then, an icon button labeled “shooting button” is displayed on the display unit 41b. In step S46, it is checked whether or not the shooting button has been pressed. If the shooting button is pressed (Yes), the process proceeds to step S47, and if the shooting button is not pressed (No), the process returns to step S45.
In step S47, the captured image is acquired together with time information and temporarily stored. Here, the time information includes information indicating date, hour and minute. In step S48, the captured image acquired in step S47 is displayed on the display unit 41b.

In step S49, it is checked whether the start button or the resume button has been pressed. When the start button or the resume button is pressed (Yes), the process proceeds to step S50, and when not pressed (No), the process returns to step S46. Here, the repetition of steps S46 to S49 is for re-shooting when the point of interest is not clearly shown in the shot image. When a plurality of captured images are acquired by repeating step S47, a plurality of captured images can be displayed on the display unit 41b in a reduced image display, and the marker displayed on the display unit 41 is moved and applied to the image to be selected. In this state, the user can select an image by pressing the “decision button” of the input unit 41c.
When the “start button” or “resume button” is pressed, tab information indicating the start of work or the resumption of work is added to the electronic file of the work record, and the status of the work record The configuration is such that the identification can be easily made.

In step S50, the selected photographed image is pasted (stored) together with the corresponding time information (actual man-hour time information) in the photo column 67a and the time information column 67b of the photo column 67 at the start of work (resumption) in FIG. Steps S45 to S50 correspond to the “first work step” recited in the claims.
Incidentally, a plurality of captured images and time information acquired in step S47 that are not selected are automatically deleted from the temporary storage. Thereafter, the icon of the “start button” or “resume button” disappears on the display unit 41b, and the “complete button” and “interrupt button” icon buttons continue to be displayed instead.

After step S50, the process proceeds to step S60, and the input of the work record is accepted according to the work instruction sheet 60. When the input of the work record according to the work instruction 60 in step S60 is accepted, it is checked whether the “interrupt button” or the “completion button” is pressed as shown in step S61 (“interrupt button or Press the complete button? ").
If the “interrupt button” or “completion button” is not pressed (No), step S50 is continued. If the “interrupt button” or “completion button” is pressed (Yes), the process proceeds to step S62.

(Accepting work records input according to work instructions)
Acceptance of work record input in accordance with work instruction 60 in step S50 differs depending on the format of work instruction 60. Here, groove alignment and groove inspection (pipe FU) shown in FIGS. 10 and 24 to 31 are performed. Illustrate according to the example of work In the state of step S60, an “OK button” and an “NG button” are displayed as icon buttons on the display unit 41b. For example, the work group information column 70, the confirmation column 62b, the determination result column 63n _{3 and the} like are exemplified below. Can be input.

First, whether the personal ID information of the RFID tag 52 read and displayed in steps S32 to S35, the qualification code indicating the contents of the qualified person's qualification, and the code indicating the affiliated company correspond to the work group information column 70, respectively. The affiliation company code that is visually confirmed and displayed as work for confirming the work team information is in the contractor column 70a, the personal ID information of the work team head is in the work team head field 70b, and the personal ID information of the other workers 51 etc. Are drawn into the operator column 70c and the qualification codes and personal ID information of the workers 51 who have the qualifications required for the operation are respectively drawn and dropped into the qualified user column 70d. This completes the entry and confirmation of the work group information column 70. In addition, the personal ID information of the worker 51 and the like who inputs the record by operating the portable terminal 41 is drawn and dropped in the recordr name field 73b. Accordingly, the time information at that time is entered in the time information column 73a.
Even if the configuration of the team scheduled at the time when the work instruction 60 is created is changed on that day, it can be easily changed as a work record.

Next, the original input of the work record will be described. As for the upstream and downstream spool number fields 62a of the welded part upstream / downstream piping data field 62, the product identification information is read from the RFID tag 44 and the process proceeds to Yes. input. Next, the marker automatically moves to the confirmation result column 63d, and visually confirms that the groove alignment method matches the method displayed in the groove alignment method column 63c, and presses the “OK button”. Then, OK is entered in the confirmation result column 63d. The marker moves to the groove surface inspection result column 63m and prompts the operator 51 to confirm the groove shape.
The operator confirms that the groove shape is correct while confirming the abbreviation code even written in the groove shape field 63k, or checking the drawing field 64b of the groove shape field 64 with the actual groove shape. Then, an “OK button” is pressed to enter OK in the groove surface inspection result field 63m. In addition, a message prompting the user to take a picture is displayed, and a photograph showing the groove shape is taken and attached to the groove surface inspection result field 63m.

Then, the marker is automatically moved to the foreign substance confirmation column 63 b _1, prompt confirmation of absence of foreign matter in groove portion operator or the like 51. The operator confirms that there is no foreign matter in the groove portion, presses the “OK button”, and enters OK in the foreign matter confirmation column 63b ₁ . Then, the marker points to the photo column 63b ₂ , a message prompting the user to take a photo is displayed, and the operator confirms that there is no foreign object in the groove portion and attaches it to the photo column 63b ₂ .
Note that it is desirable that a plurality of photographed images to be affixed are affixed so that the circumferential direction of the pipe can be confirmed to some extent.

Next, the marker moves to the confirmation item column 65 at the time of construction, and it is confirmed that there is no abnormality in each item of the confirmation items at the time of construction that the workers 51 have assigned and confirmed, and the operator applies the marker to that item. Press the “OK” button to input OK, take a picture, capture the captured image and time information, and read the RFID tag 52 of the assigned worker 51 using the RFID_R / W 41e to confirm the individual of the confirmer Enter ID information.
In this work record example, spool appearance confirmation, flow direction confirmation, piping gradient confirmation, and internal foreign matter confirmation are performed. In the spool appearance confirmation and the internal foreign matter confirmation, it is preferable to read the RFID tag 43 with the RFID_R / W 41e, and associate the product identification information of each piping member with each photographed image.

Next, the marker automatically points to the confirmation result field 63f, and the operator receives this, and then attaches an RFID tag (not shown) attached to the container containing the temporary welding rod to be used for temporary welding. The temporary welding rod / type identification information read by the RFID_R / W 41e and displayed in the temporary welding rod / type column 63e matches the temporary welding rod / type identification information displayed in the readout display unit 41b by the RFID tag. Confirm that you want to do this, press the “OK button”, and proceed to the next step of work recording.
The operator 51 confirms the temperature range indicated by the temporary preheating temperature column 63g and performs preheating, and the operator 51 confirms that the temperature sensor displays the temperature within the range, and the confirmation result column Input the “OK button” at 63h. And the workers 51 etc. perform temporary welding.

Next, the marker moves to the applicable measuring instrument fields 63p _{1 to} 63p ₅ of the groove data field 63C, and the RFID tag attached to the operator, for example, a tool / measuring instrument 45 such as a gap gauge or an angle gauge. Prompt to read 46. The operator reads the RFID tag 46, displays the type of the applicable measuring instrument, the tool / measuring instrument ID information on the display unit 41b, and determines whether it is suitable for each of the applicable measuring instrument fields 63p _{1 to} 63p _5. Check with the attached photo or model. When the applied measuring instrument is correct, an “OK” display is temporarily displayed, and the tool / measuring instrument ID information that is read from the RFID tag 46 although it is not clearly shown in the applied measuring instrument columns 63p _{1 to} 63p _5. Is entered in the corresponding column. If it is not correct or the expiration date has expired, for example, “NG” is temporarily displayed, and the tool / measuring instrument ID information is not entered in the corresponding column.

Then, the operator reads the result measured by the applicable measuring instrument determined to be correct, and inputs it to the corresponding fields 63n ₂ , 63n ₅ , 63n ₈ , 63n ₁₁ , 63n ₁₄ . Then, when the result falls within the maximum and minimum tolerance ranges described in the columns 63n ₁ , 63n ₄ , 63n ₇ , 63n ₁₀ , 63n ₁₃ , the columns 63n ₃ , 63n ₆ , 63n ₉ are automatically entered. , 63n ₁₂ , 63n ₁₅ is inputted OK, and NG is inputted when it is out of the maximum and minimum tolerance range.

  This completes the input of the work records illustrated in FIGS. Returning to step S61 in FIG. 22, if the interrupt button or the completion button is pressed and the answer is Yes, the process proceeds to step S62, where the “work target indicated by the work instruction or the work target portion is photographed and the interrupt button is pressed. Or press the completion button again ”message is displayed on the display unit 41b. Thereafter, the process proceeds to step S63 in FIG. 23 according to the connector (E). Then, an icon button labeled “shooting button” is displayed on the display unit 41b.

In step S63, it is checked whether or not the shooting button has been pressed. If the shooting button has been pressed (Yes), the process proceeds to step S64. If the shooting button has not been pressed (No), the process returns to step S63.
In step S64, the captured image is acquired together with time information and temporarily stored. Here, the time information includes information indicating date, hour and minute. In step S65, the captured image acquired in step S64 is displayed on the display unit 41b.

In step S66, it is checked whether an interrupt button or a completion button has been pressed. When the interrupt button or the completion button is pressed (Yes), the process proceeds to step S67, and when not pressed (No), the process returns to step S63. Here, the repetition of steps S63 to S66 is for redoing the imaging when the point of interest is not clearly shown in the captured image. When a plurality of photographed images are acquired by repeating step S64, a plurality of photographed images can be displayed on the display unit 41b in a reduced image display, and the marker displayed on the display unit 41 is moved and applied to the image to be selected. In this state, the user can select an image by pressing the “decision button” of the input unit 41c.
When the “interrupt button” or “completion button” is pressed, tab information indicating that the work is interrupted or completed is added to the electronic file of the work record, and the status of the work record The configuration is such that the identification can be easily made.

In step S67, the selected photographed image is pasted (stored) together with the corresponding time information (actual man-hour time information) in the photo column 68a and the time information column 68b of the photo column 68 when the work is completed (suspended) in FIG. Steps S61 to S67 correspond to the “second work step” recited in the claims.
Incidentally, a plurality of captured images and time information acquired in step S64 that are not selected are automatically deleted from the temporary storage.

In step S68, the work man-hour is calculated. Specifically, the actual work time is calculated from the two time information in the time information column 67b and the time information column 68b, and the workers who constitute the team from the number of different personal ID information entered in the work team information column 70 51 is calculated, and the actual number of man-hours (man · Hr) is added to the value already entered in the actual man-hour column 69b by multiplying the work time and the number of people.
When this work record is the start of work, no actual value is entered in the actual man-hour column 69b, so the actual man-hour (man · Hr) calculated as it is is written there. In the lower case, the actual man-hours up to the previous time have already been entered in the actual man-hour column 69b, the calculated actual man-hours are added to the value, and the result is input and displayed in the actual man-hour column 69b. Thereafter, a difference result obtained by subtracting the value of the target man-hour column 69a from the value of the actual man-hour column 69b is input and displayed in the man-hour difference display column 69c with a plus or minus sign.
When the difference result is positive, it indicates that the target man-hour has been exceeded. When the difference result is negative, the work has been completed in less work time than the target man-hour.

In step S69, it is checked whether the work is interrupted or completed. If the interrupt button is pressed in step S66, the process proceeds to step S70, where Rev. The number is incremented, and the work instruction sheet 60 is generated and stored in the storage unit 41f, leaving the part that has not been input blank. Rev. When the work instruction sheet 60 with the number increased is generated, the data in the photo column 66a in the photo column 66 when the previous process is completed (suspended) and the data in the time information column 66b are the photo column in the photo column 68 when the work is completed (suspended). 68a is replaced with the data in the time information column 68b, the data in the photo column 67a in the photo column 67 at the time of starting (resuming work), the data in the time information column 67b, and the photo column 68a in the photo column 68a at the time of completion (interruption) of work. The data in the information column 68b is deleted.
If the completion button is pressed in step S66, the process proceeds from step S69 to step S71 to determine work recording. Specifically, all the parts to be input as work records in the work instruction sheet 60 are entered, confirmation result columns 62b, 63b ₁ , 63d, 63f, 63h, 63m, judgment result columns 63n ₃ , 63n ₆ , 63n ₉ , If all of 63n ₁₂ , 63n ₁₅ , 65e, etc. have been input OK, it is determined to be acceptable, and “pass” is automatically entered in the work record determination result column 72. If the input is forgotten or NG is input, although omitted in the flowchart, the process returns to step S60, the input is performed, and the process returns to step S71.
If the NG item cannot be corrected, a failure input is made in step S71. Further, the process proceeds to step S70 of the interruption process.
After steps S70 and S71, the process proceeds to step S72, and the input of a series of work records based on the work instruction sheet 60 is completed.

As described above, even when the work record creation work based on the work instruction 60 is interrupted due to a lunch break or a support request from another team, the work record can be resumed. This is convenient for resuming the work because the current photo is left.
Sometimes work does not resume on the same day, but may resume on another day, so there is no need to check the work site even if another work team takes over and resumes the work. You can understand the current situation through photo recording and resume work.

In step S135, the construction group / worker movement information is stored in the storage unit 21c based on the area ID information included in the information related to the selected work man-hours, the work start / restart time information, and the worker personal ID information. Search from. Before starting or resuming work, search for effective construction group / worker movement information until entering the work area indicated by the area ID information.
Here, “the work area” refers to the work area indicated by the area ID information (area ID information indicated by the area number column 61g of the work instruction sheet 60) included in the information relating to the work man-hour selected in step S135. It is.
In addition, the valid construction team / worker movement information is the invalid construction team / worker movement information that is processed during the man-hour counting process and is flagged as invalid. Since the construction group / worker movement information for which the invalid flag is set is deleted from the storage unit 21c, any construction group / worker movement information is initially in a valid state.

In step S136, effective construction group / worker movement information until entering the work area is selected before the work is started or restarted.
In step S137, based on the effective construction group / worker movement information until entering the work area, the movement time for the work is calculated for each personal ID information.
In step S138, after entering the work area, the time until the start or restart of the work is calculated for each personal ID information as a preparation time for the work.

After step S138, the process proceeds to step S139 in FIG. 40 according to the connector (J), and the actual man-hours of the work for each personal ID information from the work start or restart time information and the work completion or suspension time information. Calculate as (working time).
Subsequently, in step S140, the time from the work completion or suspension time information until the user leaves the work area is calculated for each personal ID information as a cleanup time for the work.
In step S141, an invalid flag is set for the construction team / worker movement information until the work area is entered.
In step S142, the book number of the work record, Rev. A number is attached, and the travel time, preparation time, and cleanup time are stored in the construction man-hour DB 16N together with the personal ID information.

  In step S143, after the completion or suspension time information of the information related to the processed work man-hours, the work site passes through the work site entrance / exit gate without being included in the information related to other unprocessed work man-hours. It is checked whether or not the workers etc. 51 who have left are searched and detected. If the corresponding worker 51 is detected (Yes), the process proceeds to step S144. If not detected (No), the process proceeds to step S145 of FIG. 41 according to the connector (K).

In step S144, as the travel time after the work is completed, the book number of the work record, Rev. A number is assigned, and the travel time is stored in the construction man-hour DB 16N together with the personal ID information, and an invalid flag is set for the construction team / worker movement information concerned. After step S144, the process proceeds to step S145 of FIG. 41 according to the connector (K).
In step S145, a processed flag is set in the information relating to the work man-hour. In step S146, it is checked whether or not there remains information relating to the work man-hours for which no processed flag is set. If it remains (Yes), the process returns to step S134 in FIG. If there is no information relating to the number of work steps that have not been flagged in step S146 (No), the process proceeds to step S147, and it is checked whether or not valid construction team / worker movement information remains. When it remains (Yes), the process proceeds to step S148, and when it does not remain (No), the process proceeds to step S150.

In step S148, a message “Please judge man-hours by hand” is displayed on the display unit 22 (see FIG. 2).
In step S149, the remaining construction team / worker movement information is processed by manual input by the operator of the office terminal 11. That is, it is determined which work procedure manual corresponds to the travel time, the preparation time, and the cleanup time, and is stored in the construction man-hour DB 16N as such. Then, the invalid flag is set in the construction group / worker movement information.
This is because construction group / worker movement information is automatically generated as a result of the general inspection before the work of the day by the work group head and supervisor, and the general inspection work after the completion of the work of the day. This is the case.

  In step S150, the information related to the man-hours for which the processed flag is set and the construction team / worker movement information for which the invalid flag is set are deleted from the storage unit 21c. Then, a series of travel time before work, preparation time, actual man-hours, clean-up time, and travel time after work for each personal ID information, A number is added to complete the calculation.

In FIG. 42, the work group passes through the gate device 55 of “R1”, then passes through the gate device 55 of “R2”, and enters the work area # 1 designated by the work instruction sheet # 1. Yes. Here, the gate device 55 of “R1” relates to the entry / exit of the gate device 55 outside the work area # 1 designated by the work instruction sheet # 1, that is, the work area # 1 designated by the work instruction sheet # 1. The gate device 55 not to be used, for example, the gate devices 55A, 55B, and 55K (see FIG. 7). The gate device 55 of “R2” refers to the gate device 55 at the entrance / exit of the work area # 1 designated by the work instruction sheet # 1, for example, the gate devices 55C and 55E.
It takes time T1 from passing through the gate device 55 of “R1” to passing through the gate device 55 of “R2”. After entering the work area # 1, the portable terminal 41 inputs the start of work to the work instruction sheet # 1 at the time indicated by “S1-1” after the time T2 has elapsed. After that, after the time T3 has elapsed, the interruption of the work in the work instruction sheet # 1 is input at the time indicated by “F1-1”. Thereafter, the work group passes through the gate device 55 of “R2” and goes out of the work area # 1, for example, takes a break for a time T4, and again passes through the gate device 55 of “R2” to work area #. 1 at the time indicated by “S1-2”, and the portable terminal 41 inputs the resumption of work to the work instruction sheet # 1, and at the time indicated by “F1-2” after the time T5 has elapsed. The operation interruption of work instruction # 1 is input. The team passes through the gate device 55 of “R2” and goes out of the work area # 1, and passes through the gate device 55 of “R3” and enters the work area # 2. The time T6 has elapsed from passing through the gate device 55 of “R2” to passing through the gate device 55 of “R3”.
Here, the gate device 55 of “R3” refers to the gate device 55 at the entrance / exit of the work area # 2 designated by the work instruction sheet # 2, for example, the gate devices 55D and 55E (see FIG. 7).

  Then, after entering the work area # 2, after the time T7 has elapsed, at the time indicated by “S2”, the portable terminal 41 inputs the start of work to the work instruction sheet # 2. Thereafter, the bureaucracy of the work instruction # 2 is input at the time indicated by “F2” after the time T8 has elapsed. After the time T9 has elapsed from the time indicated by “F2”, the work team passes the gate device 55 of “R3” and goes out of the work area # 2, and passes the gate device 55 of “R2” after the time T10 has elapsed. Then, the work area # 1 is returned. Immediately after that, the mobile terminal 41 inputs work resumption to the work instruction sheet # 1 at the time indicated by “S1-3”, and after the time T11 has elapsed, the work instruction sheet at the time indicated by “F1-3”. Input for completion of work of # 1. The team passes through the gate device 55 of “R2” after the time T12 from the time indicated by “F1-3”, goes out of the work area # 1, and further passes the “R1” after the time T13 has elapsed. It passes through the gate device 55.

In FIG. 42, for example, the time T1 until entering the work area # 1 is the movement time before entering the work of the work instruction # 1.
The staying time in work area # 1 is T2 + T3 + T5 + T11 + T12 as shown in FIG. The work time (actual man-hour) based on the work instruction sheet # 1 is T3 + T5 + T11. The preparation time for the work of the work instruction # 1 is T2, and the cleanup time for the work of the work instruction # 1 is T12. The movement time after work of work instruction # 1 is T13.
Actually, the man-hour calculation in an artificial (man · Hr) unit is performed by multiplying these times by the number of persons constituting the work group.

The staying time in work area # 2 is T7 + T8 + T9 as shown in FIG. The work time (actual man-hour) based on work instruction # 2 is T8. The preparation time for the work of work instruction # 2 is T7, and the cleanup time for the work of work instruction # 2 is T9. The travel time between work area # 1 and work area # 2 is T6 + T10.
In fact, these times are multiplied by the number of people who make up the work team.

<Effect of man-hour management>
Next, as described above, the book number of the work record, Rev. The effect of using the results accumulated in the construction man-hour DB 16N for each numbered personal ID information, actual man-hours, preparation time, clean-up time, and travel time will be described with reference to FIGS.
FIG. 43 is an explanatory diagram illustrating an example of a work time summary table for pipe installation work. The work time tabulation table 83 includes an item number field 83a displaying "procedure No.", a work name field 83b displaying "work sequence", a work start time field 83c, a work suspension time field 83d, a work resuming time field 83e, a work It includes a completion time field 83f, an actual man-hour field 83g, a target man-hour field 83h, a target / actual man-hour difference field 83i, an area field 84, and a work team man-hour field 85.

Here, in the work name column 83b, items of a series of work names such as “carry-in”, “brush”, “Fu (groove alignment)”, “welding”, “finish”, “inspection”, and “painting”. In addition, the waiting process including the moving time and the preparation time before the start of the first work in the series of works described above ("waiting process" of procedure No. 1), and the previous work in the work procedure The cleaning time after the previous work, the moving time after the previous work, the moving time before the next work, and the preparation time before the next work Waiting process including the waiting time (procedure No. 3, 5, 7, 9, 11 and 13 "waiting process"), the cleanup time after completion of the last work in the series of work, and the moving time ( Step No. 15 “waiting step”) is included.
Incidentally, "finishing" is "welding part finishing".

Incidentally, the work interruption time field 83d and the work resumption time field 83e are appropriately increased by the number of times of the interruption and resumption.
The units of the columns 83g, 83h, and 83i are indicated as “Hr”, but more precisely, man · Hr.

  The area column 84 is provided with an area ID information column 84a in which area ID information (area number) is written, and an area division column 84b. In the area classification field 84b, for example, information related to a work area such as a passage, a room, a radiation management area, and a radiation management area outside is described.

The work group man-hour column 85 is provided for each work group, and a group head name column 85a that describes the name of the team head of the work group, a worker number column 85b that indicates the number of people configured in the work of the group, It includes an actual man-hour column 85c indicating the actual man-hour, a target man-hour column 85d indicating the target man-hour of the entire team, and a team evaluation column 85e.
This group evaluation column 85e is a column in which the manager who manages the worker evaluates the ability of the work group and inputs the result. For example, when the difference between the target man-hour and the actual man-hour (actual man-hour-target man-hour) is large on the plus side, the evaluation becomes worse.

The total number of actual man-hours for each work group is included in the information related to the work man-hours in the Rev. of work record. Since the numbered book number is included, and the personal ID information of the work team head to which an identifier indicating the work team head is added is included, the actual man-hours of the workers 51 of the work team can be easily counted. Then, the actual man-hours and the target man-hours for each work team can be compared, and the ability evaluation of each work team can be easily performed as compared with other work teams.
In addition, the waiting time can be easily counted.

In addition, when starting or resuming work, completing or interrupting work, a photo record is acquired and time information is also acquired, so when the work is completed and the next work procedure is started, or the same When the work is resumed, the previous state can be confirmed in the work record without confirming again at the work site, so that time can be saved.
In particular, when the work according to the work procedure manual is interrupted, the Rev. Based on the work record when the work is interrupted at that time, the photographed image in the photo field 68a at the time of completion (interruption) of the work is displayed in the photo field 66a at the time of completion (interruption) of the previous process. Since it automatically transcribes, the previous state can be confirmed in advance when the work is resumed. Even if the work team needs to be replaced, reliable communication is possible.

Furthermore, the following work processes can be managed. FIG. 44 is an explanatory diagram of the management display of work processes for each piping line in piping installation work.
For example, in FIG. 44, the vertical axis indicates work procedure items (specific items are omitted on the vertical axis in FIG. 44), the horizontal axis indicates the time of month display or date display, and management of work processes by piping line. A display 87 is displayed. Thus, the planned process 88 and the actual process 89 can be compared including not only the actual man-hours but also the waiting processes before and after the work item. Here, the double hatched box 88 a indicates the waiting process 88 a in the planning process 88, and the white frame box 88 b indicates the target man-hour 88 b in the planning process 88. Similarly, the coarsely shaded box 89a indicates the waiting process 89a in the actual process 89, and the densely shaded box 89b indicates the actual man-hour 89b in the actual process 89.
Then, when creating a diagram of such work process management display as an electronic file, as work record links, work results, for example, work completion images of work for each item, numerical data of actual man-hours, work execution contents, etc. When the marker is placed in the box 89b of the actual process 89, it is convenient to display the work completion image, the numerical data of the actual man-hours, the work execution contents, etc. as in the case of the ejection display. .

FIG. 45 is an explanatory diagram of the process management display for each group. In FIG. 45, the vertical axis indicates the area ID information, the horizontal axis indicates the month display time or the date display time, and how each group moves the work area and performs work. A work process management display (group dynamic management) 91 is shown. An execution schedule 94 is shown for the planning process 93, and how the execution schedule 94 plans "TB2-A", "TB2-B", "TB2-C", and "TB2-D" with area ID information. It can be displayed whether it is changing compared with the process 93.
Also in this case, it is convenient to link the work record as described above in the execution step 94.

FIG. 46 is an explanatory diagram of the man-hour management display. In FIG. 45, the ordinate indicates the man-hour, the abscissa indicates the time of month display or date display, and the man-hour management display 95 for each area, each building, the whole, and the like.
FIG. 47 is an explanatory diagram of personnel management display. In FIG. 47, the vertical axis indicates the man-hours, the horizontal axis indicates the time of month display or date display, and the personnel management display 97 for each area, each building, the whole, or the like. The vertical bars indicate job types, for example, the actual number of people (total number of people) in the execution process, divided into three job types: carry-in, brushing, welding, painting, and inspection.
Such personnel management by job type can be easily determined and counted from the work name of the work record recorded by the work group (the record entered in the work instruction 60).

Such data of the management displays 87, 91, 95, and 97 are accumulated and updated in the work performance DB 16P (see FIG. 3).
It should be noted that such a program for creating the management display 87, 91, 95, 97 data can be easily performed by a known commercially available program (software), and therefore omitted in the functional block of the information processing unit 21a in FIG. It is.

In the present embodiment, the uploading of the work instruction sheet 60 and the like from the office terminal 11 to the portable terminal 41 and the downloading of the work record from the portable terminal 41 to the office terminal 11 are performed with the communication connector 41h of the portable terminal 41 and the office work. Although the example in the case of performing by connecting with the communication terminal 25 for exclusive use of the station terminal 11 with a communication cable was demonstrated, it is not limited to this.
If a LAN cable is provided at the work site 4 and a wireless terminal connected to the LAN cable is installed in each work area or the like and wireless communication is possible between the wireless terminal and the portable terminal 41, the wireless terminal The terminal can be connected to the office terminal 11 via a LAN cable, and the uploading and downloading described above can be performed between the portable terminal 41 and the office terminal 11 as needed. In this case, the office terminal 11 can manage the progress of the execution process in real time.
