<Description of isolation range setting method>
The flow of setting the isolation range described in the work procedure will be described with reference to FIGS. 12 to 16 as appropriate with reference to FIGS.
Japanese Patent Laid-Open No. Hei 9-2009 discloses a technique for using P & ID information 211 to create an operation procedure for a process of isolating a valve for performing maintenance and inspection work of a pump connected to a pipe or performing a draining operation. Since it is described in Japanese Patent No. 91327, it will not be described in detail here.
And it supports the work to determine the setting of the isolation range and the setting of the isolation part for performing the electrical circuit isolation process for isolating the target equipment for the maintenance inspection of the electric equipment not shown in the prior art A technique using the ECWD information 213 will be described in detail below.

FIG. 10 and FIG. 11 are flowcharts showing the flow of control for assisting the worker on the implementation side to determine the isolation location that is the boundary of the isolation range. The person in charge on the execution side performs processing mainly using the work management server computer 200 and the field maintenance support server computer 300 via the field maintenance terminal device 9, but the ECWD interface 247 is ECWD isolated in terms of the functional block configuration. Processing is performed using the work procedure creation support unit 225.
The ECWD isolation work procedure creation support unit 225 includes the following as basic functions.
(1) Drawing search function (including search function input, drawing mutual search, and element search functions)
(2) ECWD drawing list generation function corresponding to search conditions (3) Selection diagram display function (4) Inspection equipment setting function (5) Isolation location setting function (6) Isolation propagation search function (7) Isolation confirmation function (8) Separation management table generation function (9) Printing function (10) Verification function Each function described above will be specifically described as needed in the description of the flowchart.

  In order to set an inspection device, it is necessary to search a drawing in which the device is described. For this purpose, a search input screen 20 as shown in FIG. 12 is prepared as a drawing search function. The search input screen 20 includes, under the title display 20a “ECWD drawing search”, a plant name column 20b for designating a plant name for inputting search conditions, and for nuclear power plants (plants), for example, Units 1 to 6 In many cases, multiple units of nuclear power generation equipment called Unit No. are installed, the Unit column 20c for designating the unit, the Major Category column 20d for designating the major category of equipment, and the number of drawings in one item of Major Category In the case where there are many volumes, a volume code column 20e for specifying the volume is provided. A drawing list display window 21 for displaying the searched drawing list is arranged below the search condition input field. Further, an ECWD drawing is searched in accordance with the input search condition and displayed on the drawing list display window 21. An icon button 20 f displayed as “Search” and one or more of the drawing lists displayed on the drawing list display window 21. Is designated by clicking the mouse, and an icon button 20g described as “display” for displaying the designated drawing is prepared.

By the way, the major categories of equipment are, for example, basic items, reactor system, radiation monitor system, nuclear reactor instrumentation system, computer, turbine system, electrical system, waste treatment system, common, ventilation air conditioning system, miscellaneous equipment , Power transmission and reception systems, service facilities, etc.
In addition to the above-mentioned functions, the drawing search function includes a drawing mutual search function for calling and displaying each sheet by the sheet number (SH. No.) described in each drawing, all ECWD drawings or a list displayed drawing. It has an element search function for extracting a specified element, for example, a drawing in which a switch of the same model is described as a target and displaying it in a list, and further designating and displaying the displayed list. Therefore, an icon button not shown in FIG. 12 is displayed.
These icon buttons are displayed in a screen state displaying an ECWD drawing.

  First, in step S11, an ECWD drawing is selected. That is, as described above, inputs from the search condition input fields 20b to 20e are received and displayed in a list. In step S12, designation of a representative ECWD drawing including an inspection device (an ECWD drawing representing the inspection device) from the list-displayed ECWD drawings is accepted. In step S13, a related chart list is generated. Steps S11 to S13 correspond to the drawing search function and the ECWD drawing list generation function corresponding to the search conditions.

FIG. 13A schematically shows a search method for generating a list of related drawings. In the initial display drawing (Base drawing) 22, a drawing and a sheet number (SH. No.) are attached to a terminal end where the wiring is electrically connected to another drawing. In this case, it is connected to four drawings whose sheet numbers are a, b, c, and d. Then, first, the drawing 22a (drawing-a) is searched. Drawing 22a is connected to two drawings with sheet numbers a1 and a2, and drawing 22b (drawing-a1) and drawing 22c (drawing-a2) are retrieved. Since drawing 22b is not electrically connected to another drawing, there is no further related drawing retrieval from drawing 22b. Also, since the drawing 22c is only electrically connected to the initial display drawing 22 (Base), there is no further related drawing retrieval from the drawing 22c.
Next, similarly, from the initial display drawing 22 to the drawing 22d (drawing-b), the drawing 22e (drawing-b1), the related drawing search of the drawing 22f (drawing-b2), and similarly from the initial display drawing 22 to the drawing 22g (drawing-c). ), Drawing 22h (Drawing-c1), Drawing 22i (Drawing-c2) Related drawing search, Initial display Drawing 22 to Drawing 22j (Drawing-d), Drawing 22k (Drawing-d1), Drawing 22m (Drawing-d2) The related drawings are searched. As a result, a related chart list 23 as shown in FIG. 13B is generated. In the related diagram list 23, the sheet number of the drawing is displayed in the display drawing column 23a in which "drawing" is displayed in the leftmost column, and the related drawing is displayed in the related drawing column 23b in which "transition drawing" is displayed on the right side thereof. The sheet number is displayed.

From the displayed related diagram list 23, the operator moves the cursor with the mouse to find and display the drawing including the inspection device (corresponding to the above-described selection diagram display function), and displays the inspection device on the ECWD drawing. Click the symbol with the mouse to specify it, and click the icon button for inspection equipment registration (not shown) with the mouse. Then, in step S14, inspection device registration is accepted, and in step S15, the inspection device is displayed in a color-changed manner so that it can be easily identified on the ECWD drawing. This corresponds to the inspection device setting function described above.
Note that the inspection device registration acceptance in step S14 can accept designation of a plurality of devices.
In step S16, an input of information incidental to inspection device registration is accepted as necessary.

Next, in step S17, the related drawings are searched again starting from the inspection device. The flow of this search is schematically shown using FIG.
In FIG. 14, the ECWD drawing in which the inspection device X is set is assumed to be an initial display drawing (Base drawing) 24 in this related drawing search. The isolation set on the downstream side of the flow or current flow of the electrical signal inspection apparatus X is that there is a connection terminal T _X possible. After setting the inspection apparatus X, in step S16, further settings that do not propagate to the downstream side, and to the processing of later-described setting condition "Lift" in the connection terminal T _X.
Thereafter, when a related drawing search is performed starting from the initial display drawing 24, the sheet number of the drawing directly related to the inspection device X is only a0. Therefore, as shown in the related diagram lists 25a to 25d attached to the right side of each ECWD drawing shown in FIG. Drawings 24b (drawing-a1) and 24c (drawing-a2) are searched as drawings related to drawing 24a (drawing-a0) and drawing 24a (drawing-a0), and further searching is lost. As a result, the related chart list 25 shown in FIG. 14B is obtained.

The operator searches for a candidate for the isolation location from the base drawing 24 according to the related diagram list 25, and inputs the isolation location settings and isolation status settings one after another. In step S18, the setting of the isolation location and the input of the isolation status setting (isolation range setting input) are received. This step S18 corresponds to the isolation location setting function described above.
In step S19, the related drawings are searched again. That is, the related diagram list 25 automatically repeats the base drawing 24 as a starting point and updates the display of the related diagram list 25 according to the isolation range setting input. As a result, the number of related drawings changes. In step S20, it is checked whether or not an icon button (not shown) labeled “Isolation range determination” is clicked (Isolation range determination?). If the isolation range is determined (Yes), the process proceeds to step S21. If not (No), the process returns to step S18.
Here, step S19 corresponds to the isolation propagation search function described above.

The operator uses the function of the book search unit 244 of the procedure manual management unit (execution side) 322 to search for the past procedure manual from the procedure manual DB 302 and describes the input of the isolation range setting described above. It is also possible to refer to the curing list described later.
A detailed method of setting and inputting the isolation range will be described with reference to FIG.
Incidentally, the sign “#” is attached in front of the number in the figure to indicate the sign number.
In the example of the ECWD drawing 27A of the sheet number a (SH # a) in FIG. 15A, with respect to the electric supply line R (line #R) and the electric supply line T (line #T) indicated by reference numeral 28c. , A switch (hereinafter abbreviated as SW) 29A is connected to the drawing of the sheet number d (SH # d), and from the electric supply line R (line #R) and the electric supply line T (line #T) A double switch 29B, a fuse 30, and a switch 29C are connected in parallel to the electricity supply line R (line #R) and the electricity supply line T (line #T) indicated by the branched reference numeral 28d. Only on one downstream side of the double switch 29B, the device 31A indicated as “device-c” is connected by the connection terminals S1 and S2. Then, it is shown that there is no further electrical supply or output of electrical signals from the device 31A to other devices. The detailed ECWD drawing of the device 31A is shown with reference to the drawing of SH # cc.
Similarly, on the downstream side of the fuse 30, a device 31B indicated as “device-b” is connected by connection terminals S1 and S2. Then, it is shown that there is no further electrical supply or output of electrical signals from the device 31B to other devices. The detailed ECWD drawing of the device 31B is shown with reference to the drawing of SH # bb.
On the downstream side of the switch 29C, a device 31C labeled “device-a” is connected via connection terminals S1 and S2. Then, it is shown that there is no further electrical supply or output of electrical signals from the device 31C to other devices. The detailed ECWD drawing of the device 31C is shown with reference to the drawing of SH # aa.

Here, the inspection equipment setting is registered for the equipment 31B and 31C as indicated by the operation of reference numeral 30a. In this inspection, it is assumed that each connection terminal (S1, S2), which is a candidate for an isolated portion, is set in a connected state, that is, as “propagation” as indicated by the operation of reference numeral 30b.
Here, the following five types of isolation state settings are prepared for connection terminals and switches that are candidates for isolation locations.
(1) “On”: Sets a device such as a switch to an on state. In this case, it is not isolated at this point and the propagation extends to the next element.
(2) “Off”: Sets a device such as a switch to an off state. In this case, it is isolated at this point and does not propagate to the next element.
(3) “Lift”: The cable is disconnected at the connection terminal, and the terminal treatment is performed in a state where it is not electrically connected. In this case, it is isolated at this point and does not propagate to the next element.
(4) “Propagation”: The cable is directly connected at the connection terminal. In this case, it is not isolated at this point and the propagation extends to the next element.
(5) “Jumper”: Connect to another element with a jumper wire, with or without removing the cable at the connection terminal. In this case, a temporary circuit connected to the ECWD drawing by a jumper line is set including grounding.

In the input of the operator's isolation range setting for step S18, when the operator sets the inspection device, the connected device (device etc.) is sequentially traced starting from the inspection device, and the next element is different from the inspection device. Change the color and make the element blink. In this way, the operator can easily find the element of the isolation part from the screen. At this time, when a plurality of inspection devices are registered in the related drawings of a series of ECWD drawings, different colors may be set for each inspection device. By doing so, it is easy to understand which inspection equipment the element relates to. Instead, on the ECWD drawing, for example, when the tip of the arrow symbol pointer is matched with the blinking candidate element of the isolation location, the inspection device number is automatically displayed in the balloon symbol. good.
In this example, the color of the device 31C is changed up to the switch 29C, and the symbol representing the switch 29C blinks. The operator sets the switch 29C to the “OFF” isolation state as indicated by the operation of the reference numeral 30c. As a result, the propagation extension from the switch 29C to the upstream is stopped.

Since the fuse 30 is a non-isolated device, it propagates as it is to the device 31B, and the symbol “SH # b” displayed on the screen indicating the boundary with the related drawing blinks. When the operator clicks the sign of “SH # b”, the screen transitions to the related drawing 27B (see FIG. 15B) including the next element whose color has been changed. Then, the color up to the switch 29D is changed and the symbol of the switch 29D blinks. The operator sets the switch 29D to the “OFF” isolation state as indicated by the operation of the reference numeral 30d.
In order to prevent forgetting to enter the isolation range setting, when transitioning between drawings is allowed, check that the isolation propagation setting for the blinking element in the drawing has been completed before that. If the operator mistakenly performs an operation for making a transition between drawings before that, it is preferable to display a warning guide by a balloon display or the like.

Thus, the setting of the isolation range is completed when the devices 31B and 31C in the ECWD drawing 27A are inspection devices. If the isolation range is determined in step S20 (Yes), the process proceeds to step S21, and a list of drawings related to the isolation range is created.
In step S22, it is checked whether or not forgetting to set the isolation state for the boundary element of the drawing related to the isolation range or the connection terminal (isolation location). If yes (Yes), the process proceeds to step S23, the drawing is displayed to prompt the setting of the isolation state, the setting input is accepted, and the process returns to step S22. At this time, it is good to blink the symbol of the isolation | separation location where the isolation | separation state is not set.
If there is no isolation state setting in step S22 (No), the process proceeds to the next, and the operator can perform an oversight check and consistency check of the isolation propagation by transitioning between drawings related to the isolation range. And Steps S22 and S23 correspond to the isolation confirmation function described above.

At this time, the screen displays three icon buttons displayed as “Quarantine range registration”, “Quarantine range correction”, and “Temporary save”. In step S24, it is checked which of the three icons has been selected. If it is detected in step S24 that the “temporary save” icon has been clicked, the process proceeds to step S25, where the work file 9a (see FIG. 1) includes a list of drawings related to the isolation range in this state and the inspection device. The data of the setting, the setting of the quarantine location, and the setting of the quarantine state are saved, and further, the operation state data of the quarantine work procedure creation support function of the ECWD interface 247 is also stored and the processing ends. By starting up the temporary storage file stored in the work file 9a again, this operation can be continued. It is convenient to prepare the temporary save function icon button on the screens after step S12.
When the “isolation range registration” icon button is clicked in step S 24, the process proceeds to step S 26, where a separation management table is generated and the process ends. Here, an example of the separation management table 31 is shown in FIG. This separation management table 31 is an example in the case of a connection terminal. The serial number of the separation management table 31 created this time, the ECWD drawing number (ECWD.NO), the panel number (panel number), the terminal block number (or coordinates), Cable. Information on NO (or terminal NO) and isolation treatment (setting state) is entered.
In addition, although not shown in figure, the apparatus name and apparatus number of the inspection apparatus which were registered by step S14 with which this isolation location are related are automatically recorded as incidental information.
If the “Isolation range correction” icon button is clicked in step S24, the process returns to step S18.
It should be noted that all the operation input history information of the operator in each step after the operation in step S11 is saved, and even if temporarily saved or continuously operated, the process returns to an arbitrary step, It may be made easier to perform the correction work without performing the work again from step S11, such as the addition of the inspection equipment, the cancellation of the specification error of the inspection equipment, or the cancellation of the setting of the isolation part.

  Note that step S14 of the flowchart in the present embodiment constitutes a target device setting means of the present invention (embodiment), step S18 constitutes an isolation state setting means and an isolation propagation search means, and step S21 constitutes an isolation range display means.

《Explanation on how to create curing list management table》
Next, the person in charge on the implementation side uses the curing list creation unit 347 of the field maintenance support server computer 300 via the field maintenance terminal device 9 to cooperate with the ECWD isolation work procedure creation support unit 225 to create the separation management table. The flow of control of work support for creating a curing list management table based on 31 will be described.
FIG. 17 is a flowchart for explaining the flow of control of work support for creating a curing list management table, and FIG. 18 is an example of a screen for registering the created curing list management table.

  In step S31, the separation management table is read, and the drawing corresponding to the isolation location is retrieved from the ECWD information 213 in the drawing DB 203 based on the drawing number of the EWCD drawing (step S32), and the drawing is displayed (step S33). In step S34, a designation input indicating whether the upstream or downstream side is the isolation range side with respect to the isolation location is accepted. Then, a related drawing search by propagation is performed on the side included in the isolation range (step S35). This operation is performed for all isolation points. Therefore, the operations from S31 to S35 are repeated for all the separation management tables. In step S36, it is checked whether or not the drawing corresponding to the isolation location has been completed, that is, whether or not the work from S31 to S35 has been completed for all the separation management tables. If not completed (No), the process returns to step S31, and if completed (Yes), the process proceeds to step S37.

In step S37, it is checked whether or not an isolation part is included inside the isolation range. If it is included (Yes), the process proceeds to step S38, the corresponding isolation part is displayed on the drawing, and a message “Issue to check the isolation part” is output and the process ends. When it is not included in step S37 (No), the process proceeds to step S39, a message “Isolated location is appropriate” is output, a curing list management table is generated (step S40), and the process ends.
Here, the fact that the isolation part is included in the isolation range means that there is a useless isolation part, and the number of isolation processes may only be increased, and the work becomes complicated.
However, conversely, by setting a small isolation range for each inspection device and finely recovering the isolated part each time maintenance inspection of the inspection device is completed, the device that has undergone maintenance inspection regardless of the recovery procedure Set up to be operable every time, even if there are multiple isolation points, even if the uppermost isolation point is restored in the order of the process, it is prevented to energize the downstream equipment during maintenance inspection There is also an idea that you can.
Note that steps S37 to S39 correspond to the verification function of the ECWD isolation work procedure creation support unit 225 described above.
In addition to the isolation range setting result verification function by the ECWD isolation procedure creation support unit 225, the isolation plans for the same equipment created by multiple departments, for example, the design department and the inspection department, are compared and compared. A function for displaying the location on the ECWD drawing is also included.
By preparing such a function, it is possible to make a flawless isolation plan.

FIG. 18 shows an inspection device / curing list management table registration screen for creating a curing list management table for the inspection target device in the curing list creation unit 347 and editing a work record of isolation processing in the curing list editing unit 364. One example of 33 is shown. This example is an example of an isolation processing curing list management table based on an ECWD drawing. The format of a curing list such as a valve operation based on a P & ID drawing is naturally different from this, but is omitted here.
In the icon button column arranged on the left side of the screen, various icon buttons are prepared so that the main menu can be selected. The screen configuration is the same as the description of the screen 60, and the description is omitted.

  The inspection device / curing list management table registration screen 33 is composed of two tables, an inspection object device management table 34 and a curing list management table 35, as shown in FIG. The inspection target device management table 34 is provided with an item number column 34 a displaying “No.”, a device name column 34 b displaying “device name”, and a device number column 34 c displaying “device number”. Yes. The data in the column 34b and the column 34c are also loaded with the device name and device number which are supplementary information when the data of the above-described separation management table 31 is called. "" And click to automatically enter.

In the curing list management table 35, a tag number column 35a which is a number assigned to the work tag 15 (refer to FIG. 1) displayed as “Tag No.”, followed by description columns 35b to 35h for information on the isolation locations, A record column 36 that describes the work record of the isolation and restoration work, and a remarks column 39 that describes the affected devices and the like are prepared.
Incidentally, the data in the columns 35b to 35h are read from the read separation management table and automatically inputted. Column 35b is the ECWD drawing number (ECWD.NO), column 35c is the panel number (panel NO), column 35d is the terminal block number (terminal block No), column 35e is the coordinate, and column 35f is the cable number (cable e.NO). ), The column 35g is input with the terminal number (terminal NO), and the column 35 is input with the isolation treatment (setting state).
Note that the tag number in the column 35a is a number set by the work tag issue support unit 272 when the work side issues a work slip by using the work slip creation / issuance management unit 271, and inputs a work record. It is entered when the manual is submitted, and is left blank at the submission stage.

  The record field 36 labeled “Implementation and confirmation” is further composed of an isolation record field 37 labeled “Quarantine confirmation” and a recovery record field 38 labeled “Recovery confirmation”. Implementation date columns 37a and 38a for inputting implementation date data, implementer columns 37b and 38b for inputting an implementer name, and witness columns 37c and 38c for entering an witness name are prepared.

  In addition, the icon buttons 55A and 55B for printing the inspection target device management table 34 and the curing list management table 35 created, the icon button 52A for returning the screen to the previous screen, the inspection target device management table 34, the curing Scroll icons 56 a, 56 b, 56 c for scrolling the list management table 35, and an icon button 57 </ b> A displaying “Register” for registering in a manual or report are prepared.

  It should be noted that by using the functions of the P & ID isolation work procedure creation support unit 223 and the ECWD isolation work procedure creation support unit 225 by the icon buttons 53A and 53B displayed as “From P & ID drawing” and “From ECWD drawing” You can search to see the data about the device and the quarantine. The work button DB 206 can be accessed and the work tag information 206b can be searched by the icon button 53C displaying “From work slip”.

<< Description of how to create and obtain work record information >>
Next, with reference to FIGS. 1 and 19, a method of using RFID tags in the issuance of work tags and the subsequent management will be described.
As shown in FIG. 1, an RFID tag 16 </ b> A is affixed to the work tag 15, and an RFID tag 16 </ b> B is affixed or built in a personal ID card 19 attached to the chest of each worker 18.

In step S51, the person in charge on the implementation side creates a procedure manual using the procedure manual management unit (implementation side) 322, obtains approval from the supervisor, and submits it to the management side in the form of electronic information (implementation procedure procedure). Writing).
In step S52, the procedure manual management unit (management side) 241 receives it, the manager in charge of the survey investigates, obtains the approval of the supervisor, and returns the approval to the implementation side (management side procedure approval). Then, the approval management unit 341 of the procedure manual management unit (implementation side) 322 registers the procedure manual in the procedure manual DB 302 (step S53 (stored in the procedure manual DB)).
In step S54, the person in charge on the management side reads the relevant manual in the work manual DB 302 using the work slip management section (management side) 229, and uses the work slip creation / issuance management section 271 to create one work subject. On the other hand, a work slip for instructing the work content for each work step is created. At this time, if the contents of the work slip include the work of attaching the work tag 15, that is, the work of isolation processing, the work tag 15 is also issued based on the curing list management table 35 (see FIG. 18) of the manual. (Administrative work form creation (issue of work tags)). At this time, when the work tag 15 is issued, work tag information is generated using the work tag issuance support unit 272, but the ID information is read through the RFID tag printer 7c, and the work tag information and the ID information are associated with each other.
In step S55, the work form creation / issuance management unit 271 registers the generated work form information 206a in the work form DB 206 (stores in the work form DB).

  In step S56, the worker on the implementation side performs the separation work of the isolation part under the presence of the field agent and the supervisor on the management side, and attaches the work tag 15 (execution of the isolation part (execution of the isolation part (work tag)). attachment)). Thereafter, in step S57, the worker on the implementation side uses the portable terminal device 13 to create a work record for the separation work of the isolation part. At that time, the RFID tag 16A of the work tag 15 is read, the work tag ID is specified, and the work tag information related to the work tag 15 is related. Further, the worker on the implementation side, the field agent, and the witness on the management side The information of the RFID tag 16B of the personal ID card 19 is read out and transmitted to the work management server computer 200 in addition to the work record information as information for identifying the worker, the on-site agent and the witness, respectively (work record from the portable terminal device) Send information).

In step S58, the work tag management unit 231 of the inspection / isolation management unit (management side) 227 receives and refers to the process information in the process DB 208 by the process management interface 232 and corresponds to the work record information in the inspection / isolation DB 207. Update inspection / quarantine information (reflect in inspection / quarantine DB).
In step S59, the inspection / isolation management unit (management side) 227 transfers the work record information to the execution side and notifies that the corresponding inspection / isolation information has been updated (notification to the execution side).
In step S60, the inspection / isolation information collection unit 373 of the inspection / isolation interface (execution side) 327 collects work record information (collection of work record information).
Thereafter, maintenance inspection work is performed on the inspection target device.

  When the maintenance / inspection work for the inspection target device is completed, in step S61, the worker on the implementation side carries out the restoration work for the isolated portion in the presence of the field agent and the witness on the management side, and the work tag 15 is removed. (Implementation of recovery work for isolated locations (work tag collection)). Thereafter, in step S62, the worker on the implementation side uses the portable terminal device 13 to create a work record for the work for recovering the isolated portion in the same manner as in step S67, and transmits it to the work management server computer 200 (from the portable terminal device to the work Send record information). Thereafter, the control proceeds from step S62 to step S63. In addition, after the work of step S61, the process proceeds to the work of step S66 (editing of the curing list).

In step S 63, the work tag management unit 231 of the inspection / isolation management unit (management side) 227 receives and refers to the process information in the process DB 208 by the process management interface 232 and corresponds to the work record information in the inspection / isolation DB 207. Update inspection / quarantine information (reflect in inspection / quarantine DB).
In step S64, the inspection / isolation management unit (management side) 227 transfers the work record information to the execution side and notifies that the corresponding inspection / isolation information has been updated (notification to the execution side).
In step S65, the inspection / isolation information collection unit 373 of the inspection / isolation interface (execution side) 327 collects work record information (collection of work record information).
Note that the work record information for the separation and separation work collected in steps S60 and S65 is stored in an area set in advance in a storage device (not shown) of the on-site maintenance support server computer 300, and the above-described inspection / Access can be made using the isolation management interface (implementation side) 327 and the curing list editing unit 364.

In step S66, the person in charge on the implementation side transfers the work record information to the record column 36 of the cure list management table as shown in FIG. 18 using the cure list editing section 364 of the report management section (implementation side) 323. (Edit the curing list). Specifically, the work record information collected in step S60 and step S65 is read and transferred.
After that, edit the contents of other items in the report, for example, the replacement parts list, the used instrument / test equipment list, and the used tool / equipment list, and create a report (edit the other items and report Writing).

  Steps S57 and S62 in the flowchart in the present embodiment constitute work record creation means of the present invention (embodiment).

  As described above, according to the present embodiment, in the curing list creation unit 347, the inspection target device including inspection / isolation information such as the name and device number of the maintenance inspection target device, the isolation location, and the isolation status based on the separation management table 31. Since the management table 34 and the curing list management table 35 are created, the burden on the operator is reduced. The separation management table 31 uses the P & ID interface 245, the single-line diagram interface 246, and the ECWD interface 247 to search the CAD information drawing for the drawings including the inspection device and related drawings, and check the inspection device on the drawing. Can be used to search for quarantine propagation, and quarantine locations can be set easily. In particular, the ECWD interface 247 can be used to support the setting of the isolation range using ECWD drawings so far, the burden on the operator can be reduced, and human errors such as transcription can be eliminated. .

Furthermore, based on the curing list management table 35 of the procedure manual created and submitted by the implementation document management unit (implementation side) 322, the management side uses the work document management unit (management side) 241 It is possible to issue work tags when issuing (instructions) accurately and without error.
In particular, the RFID tag 16A is affixed to the work tag 15, and the isolation processing of the isolation part and the creation of the work record of the recovery work are performed by reading the ID information of the RFID tag 16A affixed to the work tag 15. Therefore, the complexity of manual input is reduced. In addition, human error induction can be prevented.
Further, the forgotten collection work tag 15 can be easily detected by reading the collected work tag 15 with an RFID tag reader and comparing it with the work record of the work tag management unit 231.
