Description

  The present invention relates to a plant facility management and maintenance support system and a management and maintenance method that assist in identifying a generation source when a failure such as a plant alarm occurs, and support efficient troubleshooting.

Conventionally, for example, in Patent Documents 1 and 2, device information written on CAD (Computer Aided Design) drawings such as P & ID (Piping & Instrumentation Diagram: system diagram, piping instrumentation diagram), single-line diagram, etc. For example, a technique is described in which an automatic search is performed using an association between a model, a system, a device (equipment number), and a sheet number of a drawing, and an isolation range for performing maintenance work on plant equipment is determined on the drawing. Has been.
In the isolation range, devices included in the isolation range, for example, isolation work by attaching a tag for maintaining the off state of a switch for controlling on / off operation, and devices included in the isolation range are included. The alarm signal of the related instrumentation that performs the alarm action using the signal output from the control signal and the control signal to the related control device that controls on the downstream side, floating the wiring terminal in the control device housing, jumper This includes the work of attaching and bypassing control and alarms.

For example, the details of related instrumentation for alarm operation are in the form of CAD drawings, alarm output relationship diagram of soft logic diagram, alarm output relationship diagram of PI / O (Process Input Output) table diagram, and ECWD (Elementary Control Wiring Diagram). : Control device development connection diagram). Patent Document 3 describes a technique for setting terminals and switches in a control device housing that is used as a boundary for isolating devices included in an isolation range without being overlooked between a plurality of related drawings of ECWD.
Incidentally, depending on the plant maker, the PI / O table diagram may be included in the software logic drawing collection as an accompanying drawing of the software logic diagram, but here it is treated as another name for easy understanding.

  Until now, IBD (Interlock Blok Diagram) that shows the system specifications (including P & ID and single-line diagram) and logical signals in block diagrams, which are upstream books printed on paper, from plant manufacturers to customers. : Interlock block diagram) and detailed design books such as soft logic diagrams, PI / O table diagrams, ECWD, etc. are delivered in the form of hardware drawings printed on paper.

By the way, IBD is not created in the form of a CAD drawing at the plant maker at present, but it is associated with the alarm output drawing of the soft logic diagram or PI / O table diagram which is a CAD drawing by attribute information. Thus, it is not possible to search for a drawing of a soft logic diagram, a PI / O table diagram, or ECWD from the drawing, or, conversely, a drawing search of a IBD from a soft logic diagram, PI / O table drawing, or ECWD.
In an example of a nuclear power plant, there are thousands of IBD drawings, tens of thousands of soft logic diagrams, and about 10,000 drawings of ECWD.

  By the way, when an alarm signal indicating a failure or abnormality occurs in the operating plant, the customer can further troubleshoot the software logic diagram representing the physical signal, which is a thick collection of drawings, and ECWD, IBD, which represents a logical signal that is a collection of drawings in a block diagram, is tracked, and the determination of the source of the failure and the influence range is performed. However, since there is no attribute information related to the sheet number (sheet number) between drawings between drawings of IBD, soft logic diagram, PI / O table diagram and ECWD, the relationship between drawings is gained through experience. If you are not an engineer who understands the problem, the IBD, which is an upstream book, and the soft logic diagram, PI / O table diagram, and ECWD, which are detailed design books, are searched to identify the source of failure and the range of influence. It took time to make a decision, and there was a problem that a quick response was not possible.

  Specifically, at present, an experienced engineer can use signal names (in the soft logic diagrams, PI / O table diagrams, and ECWD drawings from the IBD drawing information of the upstream books based on the alarms to indicate the signal names ( Upstream of the signal that outputs an alarm based on the information of the character information), logic pattern (AND logic code, OR logic code, WITH logic code, WITHOUT logic code, NAND logic code, NOR logic code, NOT logic code, etc.) Then, the related equipment is traced, and the source of the abnormality or failure is identified and the influence range is investigated manually, and is checked across the various drawings described above. For this reason, it is very time consuming and troublesome to identify the source of the abnormality or failure and investigate the range of influence.

  For example, in the central control room of a nuclear power plant, an alarm indicating a final abnormality or failure is displayed on the monitoring screen of a monitoring device that monitors the operation state of the nuclear power plant, and the alarm of IBD is described. Even if the sheet number is found, it is possible that there are too many devices, etc., even if the IBD is registered as a CAD drawing, so that the original device that reaches the output of the alarm corresponds to the alarm, Associating the attribute information with each device in the ECWD or soft logic diagram drawing only takes a lot of effort to input the attribute information, and helps to quickly estimate the device that shows the original failure or abnormality. Must not.

  The present invention solves the above-described conventional problems. A detailed design book is searched from an IBD warning signal, which is an upstream book, to quickly estimate the source of the warning, or to quickly determine the range of influence. It is an object of the present invention to provide a management maintenance support system and a management maintenance method that can be investigated.

  In order to solve the above-mentioned problem, the present invention designates a drawing retrieval unit that retrieves a drawing including a device to be isolated from a drawing storage unit that stores drawing information, and a device on the drawing retrieved by the drawing retrieval unit. And an isolation operation state setting means for determining an isolation range using the next operation device connected to the device as an isolation boundary and setting an operation state for isolation in each of the operation target devices existing in the isolation range And when an alarm signal is output downstream according to the operation state of each operation target device existing in the isolation range set by the isolation operation state setting means, the alarm signal is output to the device and the operation target. A quarantine information list creating unit that is associated with a device and registered in the quarantine information list, and a quarantine information list that is created by the quarantine information list creating unit is stored in the quarantine information list storage unit. The information list storage means and the alarm signal are designated, and the isolation target device or the operation target device is searched from the isolation information list stored in the isolation information list storage means, causing the alarm signal. And an alarm signal cause estimating means for estimating the device.

  At this time, it is desirable that the alarm signal cause estimating means further retrieves and presents a drawing including a device causing the alarm signal from the drawing storage means.

  According to the present invention, the quarantine information list created at the time of maintenance and inspection work is accumulated, the quarantine target device or the operation target device is searched from the stored quarantine information list, and the device that causes the alarm signal is obtained. Can be estimated.

Quarantine process switches ECWD information 203c of ECWD (control panel wiring) 203c based on ₁ control panel using ECWD isolation work procedure creation supporting unit 225, processing to remove the terminal, when the jumper processing, etc., Ya upstream On the downstream side, some instruments and devices that output alarm signals indicating abnormalities or failures are included in the panel or related panels. The ECWD isolation work procedure creation support unit 225 according to the present embodiment traces the current supply line to the downstream side of the part subjected to the isolation process, and reaches the alarm signal by tracing the signal line upstream and downstream of the part subjected to the isolation process. It has a feature in that it has a function of automatically searching for things.

  When, for example, the control panel controller 63-1, which controls the rotational speed of the pump 63, as shown in FIG. Since the control signal of the pump 63 is not output from the control panel controller 63-1, the control device outputting the target value signal of the rotation speed signal to -1 detects the abnormality of the control panel controller 63-1. Alarm output.

  Therefore, when the operator of the on-site maintenance terminal device 9 creates an isolation work procedure using the ECWD isolation work procedure creation support unit 225, it automatically detects the related ECWD information 203c and detects an alarm signal. When referring to the plant operation rule information 203g of the drawing DB 203B using the book / drawing DB search unit 244B, it should be isolated so that the warning signal is not output, or leave the warning signal as it is, Make sure it is not isolated so that the safety of redundancy is not reduced.

  Here, as shown in FIG. 9, the controller inputting the control signal to the control panel controller 63-1 (see FIG. 5) cannot receive the feedback signal from the control panel controller 63-1, so that the control panel controller It is determined that the fault is a heavy fault of 63-1, and the signal “control device serious fault (RAL0295-23)” is output to the alarm control controller AUXC001 (see FIG. 10). However, based on the plant operation rule information 203g. In order not to reduce the safety of the redundancy, it is made non-isolated, and the No. in the serial number column 82 of the reference non-isolation alarm column 92 is set. Corresponding to the second row, “control device serious failure (RAL0295-23)”, “RAL4077”, “RAL0295”, “XXXA-ΔΔΔΔΔ” are entered in the respective columns 92a, 92b, 92c, and 92d. To do.

  In addition, since the controller that inputs the control signal to the motor-operated valve 64 (see FIG. 5) that is the flow rate adjustment valve cannot receive the feedback signal from the control panel controller 64-1, It is determined that there is a failure, and a signal “control device serious failure (RAL 1333-24)” is output to an alarm control controller (not shown). However, the safety of redundancy is ensured based on the plant operation rule information 203g. In order not to decrease, it is made non-isolated, and the No. in the serial number column 82 of the reference non-isolation alarm column 92 is set. Corresponding to the row 7, “control device serious failure (RAL1333-24)”, “RAL5044”, “RAL0301”, “XXXA- □□□□” are entered in the respective columns 92 a, 92 b, 92 c, 92 d. .

("Implementation of work to recover the quarantine (work tag collection)"). After that, in step S12, 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 S07, and transmits it to the work management server computer (management side) 200 ( "Send work record information from portable terminal device"). Thereafter, control proceeds from step S12 to step S13.
In addition, after the work of step S11, the process proceeds to the work of step S16 ("curing list editing").

In step S 13, the work tag management unit 231 of the inspection / isolation management unit (management side) 227 of the work management server computer (management side) 200 receives the work record information transmission from step S 12, and the process management interface 232 performs the process. The inspection / isolation information corresponding to the work record information in the inspection / isolation DB 207 is updated with reference to the process information in the DB 208 (“reflect in the inspection / isolation DB”).
In step S14, the inspection / isolation management unit (management side) 227 of the work management server computer (management side) 200 transfers the work record information to the execution side and notifies that the corresponding inspection / isolation information has been updated. (“Notify the implementation side”)
In step S15, the inspection / isolation information collection unit 373 of the inspection / isolation management interface (implementation side) 327 of the on-site maintenance support server computer (implementation side) 300 collects work record information (“collection of work record information”).

  In addition, the work record information for the separation and separation work and the recovery work collected in step S10 and step S15 is stored in an area set in advance in a storage device (not shown) of the on-site maintenance support server computer (implementation side) 300, It can be accessed using the inspection / isolation management interface (implementation side) 327 and the curing list editing unit 364 described above.

In step S <b> 16, the person in charge on the implementation side uses the report list editing unit 364 of the report management unit (implementation side) 323 of the field maintenance support server computer (execution side) 300 to record work record information in the record column of the cure list 80. Is posted ("Edit Curing List"). Specifically, the work record information collected in step S10 and step S15 is read and transferred.
After that, in step S17, the contents of other items in the report, such as the replacement parts list, the used instrument / test equipment list, and the used tool / equipment list, are also edited to create a report and stored in step S01B. The attached isolation-alarm association list 140 is attached.

  In step S18, the person in charge on the implementation side uses the approval management section 361 (see FIG. 3) of the report management section (execution side) 323 of the field maintenance support server computer (execution side) 300, and then passes through the supervisor's approval procedure. The management side submits (transmits) the report created in step S16 and the quarantine-alarm association list 140 to the work management server computer (management side) 200 in the form of an electronic file via the network 3. Thereafter, the process proceeds to step S19 in FIG. 15 according to the connector (1).

  In step S19, the report management unit (management side) 251 (see FIG. 2) of the work management server computer (management side) 200 receives the submitted report, and the person in charge on the management side receives the report management unit (management Side) 251 (see FIG. 2) is used to approve the report through the supervisor's approval procedure, proceed to step S20, store the approved report in the report DB 210, and implement the on-site maintenance support server computer (implementation) The approved report is also transmitted to (300) ("store in report DB and send to implementation side"). In response, the person in charge of the site maintenance support server computer (implementation side) 300 reports the report to the supervisor with the function of the approval management unit 361 of the report management unit (implementation side) 323, The approved report is stored in the report DB 303.

  In step S21, the person in charge on the management side is attached to the report using the function of the isolation-alarm relation editing unit 255 of the report management unit (management side) 251 of the work management server computer (management side) 200. The quarantine-alarm association list 140 (see FIG. 21) is temporarily stored. In step S22, the person in charge on the management side uses the attached quarantine-alarm association list 140 for the failure alarm cause search server computer 600. When transferred to (see FIG. 1), the failure alarm cause search server computer 600 receives the isolation-alarm association list 140 and automatically isolates only new information in the isolation-alarm association list 140. It is stored (accumulated) in the relation DB (quarantine information list accumulating means) 211.

  Now, preparation of procedure, approval of procedure, execution of maintenance and inspection work, collection of work records, creation of maintenance report and creation of isolation-alarm association list 140, approval of report, isolation-alarm association The entire work related to the maintenance work of storing the list 140 is completed.

Next, the flow of creating the curing list 80 and creating the isolation-alarm association list 140 will be described with reference to FIGS. FIGS. 16 to 19 are flowcharts showing the flow of generation of a curing list (isolation list) and creation of an isolation-alarm association list.
This processing is performed by the P & ID isolation work procedure creation support unit 223, the single-line diagram isolation work procedure creation support unit 224, the ECWD isolation work procedure creation support unit 225, the curing list editing unit 347, and the field maintenance support server computer (execution side) 300. This is done in the isolation-alarm association list editor 347B included in the curing list editor 347A.

  In step S31, the selection of the isolation level is accepted. The selection of the isolation level means that the person in charge on the site maintenance terminal device 9 who accesses the field maintenance support server computer (implementation side) 300 accesses the P & ID isolation work procedure creation support unit 223 for the function, single line connection It depends on which one of the drawing isolation work procedure creation support unit 224 and the ECWD isolation work procedure creation support unit 225 is selected to create the isolation work procedure manual. Here, “system equipment” is used when the P & ID isolation work procedure creation support unit 223 is used, “power supply device” is used when the single-line diagram isolation work procedure creation support unit 224 is used, and the ECWD isolation work procedure creation support unit 225 is used. The case of use is displayed as “control panel”.

In the case of “system equipment”, the process proceeds to step S32. In the case of “power supply apparatus”, the process proceeds to step S61 in FIG. 19, and in the case of “control panel”, according to the connector (B). The process proceeds to step S71 in FIG. At this stage, the curing list (in the middle of creation) 80 in the format shown in FIGS. 7 to 9 is automatically displayed as a pop-up screen on the screen of the display device of the on-site maintenance terminal device 9.
In step S32, the person in charge uses the book / drawing DB search unit 244B to search and display the drawing of the relevant P & ID information 203a from the drawing DB 203B, and uses the P & ID isolation work procedure creation support unit 223. The P & ID isolation work procedure creation support unit 223 accepts the specification of the isolation range 69 by the person in charge on the system diagram (P & ID).

  In step S33, registration of the specified range of isolated devices is accepted as a main device in the curing list (in the process of creation) 80. For example, in the example shown in FIG. 5, a frame is set in the isolation range 69, and the devices included therein are displayed in different colors, and the pump 63, electric valves 62 and 64, and pump drain valve included in the isolation range 69 are displayed. By specifying 65 and the manual valves 66 and 67 individually, the device number is automatically input to the device number column 83 and the related device number column 89, and is also input to the main / sub column 87 as the main device.

In step S34, it is checked whether or not the registration of the main device has been completed. This can be confirmed by checking whether or not all of the devices in which the isolated range 69 is frame-set and the devices included therein are displayed in different colors are selected. If the registration of the main device is completed (Yes), the process proceeds to step S35, and if not (No), the process returns to step S33.
In step S35, selection of the main device is accepted from the curing list (in the middle of creation) 80. In this state, the person in charge accepts manual entry of the location field 84, the isolation status field 85, the recovery field 86, and the remarks field 88. For example, an operation state setting input for isolation (setting an operation state for isolation) is received in the isolation state column 85, and an operation content setting input at the time of recovery of the device or the like is received in the recovery column 86.

  In step S36A, if there is an instrumentation device related to the device No specified in step S35 on the P & ID, the person in charge determines whether or not isolation processing is necessary for the instrumentation device. Then, an instrumentation device that requires isolation processing is designated and input as a slave device (designation of a slave instrumentation device is designated on the P & ID). The designation input as the slave device is that the device No. of the instrumentation device designated in the device No column 83 of the curing list 80 is input by selecting and designating the device No. of the relevant instrumentation device. The device is input in accordance with the master / subordinate column 87, and the device number in the device number column 83 selected in step S35 is input to the related device number column 89.

For example, in FIG. 7, when the device number “XXXA-PUMP-020-1” in the device number column 83 is selected and the control panel controller 63-1 or the on-site thermometer 63-2 in FIG. Can be designated as a slave device. After that, the person in charge accepts manual entry of the slave device location field 84, the isolation status field 85, the recovery field 86, and the remarks field 88. For example, an operation state setting input for isolation (setting an operation state for isolation) is received in the isolation state column 85, and an operation content setting input at the time of recovery of the device or the like is received in the recovery column 86.
The processing step of this step S36A is described in the claims “When a device on the drawing searched in the drawing search step is designated, the next operation device connected to the device is set as an isolation boundary. This corresponds to the “isolation operation state setting step of determining and setting an operation state for isolation for each of the operation target devices existing in the isolation range”.

  In step S36B, a single-line diagram relating to the selected main device is searched and displayed using the book / drawing DB search unit 244B. In step S37, the person in charge searches for a device such as a switch from the displayed single-line diagram, and registers the device necessary for the isolation process as a device according to the curing list (in the middle of creation) 80. After that, the person in charge accepts manual entry of the slave device location field 84, the isolation status field 85, the recovery field 86, and the remarks field 88. For example, an operation state setting input for isolation (setting an operation state for isolation) is received in the isolation state column 85, and an operation content setting input at the time of recovery of the device or the like is received in the recovery column 86.

In step S38, it is checked whether or not the registration of the slave device for the master device registered in the curing list (in the middle of creation) 80 has been completed. This is determined by whether or not the person in charge has operated the icon button to proceed to the next step. If registration of the slave device to the main device is completed (Yes), the process proceeds to step S39, and if not (No), the process returns to step S35.
In step S39, selection of the main device is accepted from the curing list (in the middle of creation) 80. In step S40, the person in charge uses the book / drawing DB search unit 244B to search and display the ECWD, soft logic diagram, and PI / O table diagram of the instrumentation related to the main device selected in step S39 from the drawing DB 203B. Let Here, the ECWD isolation work procedure creation support unit 225 is automatically activated to search the drawing data.

  In step S41, the person in charge determines whether or not alarm bypass is necessary based on the PI / O table diagram (alarm output) and the plant operation rule information. If alarm bypass is necessary, the process proceeds to step S42 of FIG. 17 according to the connector (C), and if alarm bypass is not required, the process proceeds to step S44 of FIG. 17 according to the connector (D).

  In step S42, the ECWD isolation work procedure creation support unit 225 automatically searches terminals, switches, and jumpers for the ECWD drawing, displays the color change, and the person in charge selects a target for bypass processing. Make it easy to do. Then, the person in charge selects the signal name to be bypassed, terminal No. (or switch No., jumper part No., device No.), ECWD sheet No., soft logic diagram sheet No., PI / O table diagram sheet No. It is registered in the curing list (in the middle of creation) 80 by designating it on the ECWD drawing. This means that the data is automatically entered in the columns 91a to 91c in FIG. 8 in the row of the device number of the main device in the device number column 83 in FIG.

Here, the signal name to be bypassed, that is, not to be output or input, is not limited to the alarm signal but also includes a control signal. This is because the slave device receives a control signal from the upstream, starts operating suddenly at the time of recovery, becomes a pump whose rotational speed is controlled, and includes the purpose of preventing the valve whose opening degree is adjusted from starting abnormal operation It is.
At this time, for example, an operation state setting input for isolation (setting the operation state for isolation) is received in the isolation state column 85, and an operation content setting input at the time of recovery of the device or the like is received in the recovery column 86.

  In step S43, the person in charge searches for the sheet No. of the IBD based on the signal name specified in step S42 using the book / drawing DB search unit 244B and Register in the IBD sheet No. column 91d of the main device isolation alarm column 91. Thereafter, the process proceeds to step S46.

In step S44, the person in charge searches the displayed ECWD drawing to see if there is an ECWD sheet No. related to the alarm signal. If there is, the signal name, the ECWD sheet No. related thereto, and the soft logic diagram Sheet No., PI / O table diagram Sheet No., etc. are registered in the columns 92a to 92c of the reference non-isolation alarm column 92 of the curing list (in the middle of creation) 80.
By the way, the soft logic diagram sheet No., PI / O table diagram sheet No. specifies the signal name of the alarm signal on the ECWD drawing and uses the book / drawing DB search unit 244B to create the soft logic diagram, PI / O. It can be easily obtained by searching the table diagram.

  In step S45, the person in charge searches for the sheet No. of the IBD based on the signal name specified in step S44 using the book / drawing DB search unit 244B and The information is registered in the IBD sheet number column 92d of the reference non-isolation alarm column 92 of the slave device. Thereafter, the process proceeds to step S46.

In step S46, it is checked whether or not the instrumentation process related to the selected main device has been completed. This is determined by whether or not the person in charge has operated the icon button to proceed to the next step. If the instrumentation process for the selected main device has been completed (Yes), the process proceeds to step S47. If not (No), the process returns to step S39 according to the connector (E).
Incidentally, steps S39 to S45 are a flow required when the main device to be isolated is a control device. If the main device is not a control device, an icon button is prepared so that a jump can be performed. .

  In step S47, the selection of the slave device registered in steps S36A and S37 in the curing list (in the middle of creation) 80 is accepted. In step S48, the ECWD, soft logic diagram, and PI / O table diagram of the instrumentation related to the selected slave device are retrieved from the drawing DB 203B and displayed. Here, the ECWD isolation work procedure creation support unit 225 is automatically activated to search the drawing data.

In step S49, the person in charge determines whether or not alarm bypass is necessary based on the PI / O table diagram (alarm output) and the plant operation rule information. If alarm bypass is necessary, the process proceeds to step S50, and if alarm bypass is not necessary, the process proceeds to step S52.
In step S50, the ECWD isolation work procedure creation support unit 225 automatically searches terminals, switches, and jumpers for the ECWD drawing, displays the color change, and the person in charge selects a target for bypass processing. Make it easier to do. At this time, for example, an operation state setting input for isolation (setting the operation state for isolation) is received in the isolation state column 85, and an operation content setting input at the time of recovery of the device or the like is received in the recovery column 86.
The processing step of this step S50 is described in the claims “When a device on the drawing searched in the drawing search step is designated, the next operating device connected to the device is set as an isolation boundary. This corresponds to the “isolation operation state setting step of determining and setting an operation state for isolation for each of the operation target devices existing in the isolation range”.

  Then, the person in charge selects the signal name to be bypassed, terminal No. (or switch No., jumper part No., device No.), ECWD sheet No., soft logic diagram sheet No., PI / O table diagram sheet No. It is registered in the curing list (in the middle of creation) 80 by designating it on the ECWD drawing. This means that the data is automatically entered in the columns 91a to 91c in FIG. 8 in the row of the slave device in the device number column 83 in FIG.

  Here, the signal name to be bypassed, that is, not to be output or input, is not limited to the alarm signal but also includes a control signal. This is because the slave device receives a control signal from the upstream, starts operating suddenly at the time of recovery, becomes a pump whose rotational speed is controlled, and includes the purpose of preventing the valve whose opening degree is adjusted from starting abnormal operation It is.

  In step S51, the person in charge searches for the sheet No. of the IBD based on the signal name specified in step S50 using the book / drawing DB search unit 244B. The information is registered in the IBD sheet number column 91d of the isolation alarm column 91 of the slave device. Thereafter, the process proceeds to step S54 in FIG. 18 according to the connector (F).

In step S52, the person in charge searches the displayed ECWD drawing to see if there is an ECWD sheet No. related to the alarm signal. If there is, the signal name, the ECWD sheet No. related thereto, and the soft logic diagram Sheet No., PI / O table diagram Sheet No., etc. are registered in the columns 92a to 92c of the reference non-isolation alarm column 92 of the curing list (in the middle of creation) 80.
By the way, the soft logic diagram sheet No., PI / O table diagram sheet No. specifies the signal name of the alarm signal on the ECWD drawing and uses the book / drawing DB search unit 244B to create the soft logic diagram, PI / O. It can be easily obtained by searching the table diagram.

  In step S53, the person in charge searches for the sheet No. of the IBD based on the signal name specified in step S52 by using the book / drawing DB search unit 244B. The information is registered in the IBD sheet number column 92d of the reference non-isolation alarm column 92 of the slave device. Thereafter, the process proceeds to step S54 in FIG. 18 according to the connector (F).

  In step S54, it is checked whether or not the instrumentation process related to the selected slave device has been completed. This is determined by whether or not the person in charge has operated the icon button to proceed to the next step. If the instrumentation process for the selected main device has been completed (Yes), the process proceeds to step S55. If not (No), the process returns to step S47 according to the connector (G).

In step S55, the person in charge uses the isolation-alarm association list editing unit 347B to the isolation alarm column 91 and the reference non-isolation alarm column with respect to the curing list (in the middle of generation) 80 generated by the curing list editing unit 347A. The item of the main device and the slave device described in 92 is extracted, and the quarantine-alarm relation list 140 is created and stored in the quarantine-alarm relation DB 305.
In step S56, the curing list editing unit 347A deletes the quarantine warning column 91 and the reference non-quarantine warning column 92 from the created curing list (in the middle of creation) 80 by the operation of the person in charge. A submitted version is created and saved in the manual DB 302 as part of the manual.

  Although not shown in the figure, an isolation recording column 37 and a recovery recording column 38 are provided as a recording column 36 shown in FIG. In the column 37, an implementation date column 37a, an implementer column 37b, and an witness column 37c are arranged, and in the recovery record column 38, an implementation date column 38a, an implementer column 38b, and an witness column 38c are arranged, It is preferable to use a work record format.

  When the process proceeds from step S31 in FIG. 16 to step S61 in FIG. 19 according to the connector (A), the person in charge searches the drawing DB 203B for the drawing of the single-line diagram information 203b using the book / drawing DB search unit 244B. The single line connection diagram isolation work procedure creation support unit 224 is used. The single-line connection diagram isolation work procedure creation support unit 224 receives the designation of the isolation range 79 by the person in charge on the single-line connection diagram. In step S62, registration of the specified range of isolated devices is accepted as a main device in the curing list (in the middle of creation) 80. At that time, an operation state setting input for isolation (setting an operation state for isolation) is received in the isolation state column 85, and an operation content setting input at the time of recovery of the device or the like is received in the recovery column 86.

  In step S63, it is checked whether or not registration of the main device has been completed. This can be confirmed, for example, by setting the frame of the isolation range 79 of FIG. 6 and selecting all the devices that are displayed in different colors. If the registration of the main device is completed (Yes), the process proceeds to step S64. If not (No), the process returns to step S62.

  In step S64, selection of the main device is accepted from the curing list (in the middle of creation) 80. In this state, the person in charge accepts manual entry of the location field 84, the isolation status field 85, the recovery field 86, and the remarks field 88. For example, an operation state setting input for isolation (setting an operation state for isolation) is received in the isolation state column 85, and an operation content setting input at the time of recovery of the device or the like is received in the recovery column 86.

  In step S65, the person in charge searches for a control panel, system equipment, etc. on the downstream side that is fed from the main equipment specified in step S64 on the single-line diagram, and follows the curing list (in the middle of creation) 80. Accepting and registering specified input as a device. Specifying and inputting the slave device as the slave device is performed by selecting and specifying the control panel No. and the device No. of the system device, so that the board No. or the device No. The device is input according to the master / subordinate column 87, and the device number in the device number column 83 selected in step S64 is input to the related device number column 89. After that, the person in charge accepts manual entry of the slave device location field 84, the isolation status field 85, the recovery field 86, and the remarks field 88.

  In step S66, it is checked whether or not the registration of the slave device for the master device registered in the curing list (in the middle of creation) 80 is completed. This is determined by whether or not the person in charge has operated the icon button to proceed to the next step. When the registration of the slave device with respect to the main device is completed (Yes), the process proceeds to step S39 of FIG. 16 according to the connector (H). Otherwise (No), the process returns to step S64.

When the process proceeds from step S31 in FIG. 16 to step S71 in FIG. 20 according to the connector (B), the person in charge uses the ECWD isolation work procedure creation support unit 225, and the ECWD isolation work procedure creation support unit 225 specifies the control panel. And searches for the uppermost sheet of ECWD of the control panel.
In step S72, the person in charge uses the ECWD isolation work procedure creation support unit 225, and the ECWD isolation work procedure creation support unit 225 accepts designation of an isolation range (not shown) on the ECWD sheet. In step S73, the specified range of isolated devices is registered in the curing list (in the middle of creation) 80 as a main device. Then, for example, an operation state setting input for isolation (setting an operation state for isolation) is received in the isolation state column 85, and an operation content setting input at the time of recovery of the device or the like is received in the recovery column 86.
In step S74, it is checked whether or not the registration of the main device has been completed. This can be checked by checking whether the person in charge has operated the icon button for the next step. If the registration of the main device is complete (Yes), the process proceeds to step S75. If not (No), the process returns to step S73.

In step S81, a new quarantine-alarm relation list 140 received as an electronic file in a predetermined format is read. In step S82, each item is checked against the quarantine-alarm association list 140 already stored in the quarantine-alarm relationship DB 211. Here, "each item" means every line of the serial number column 141 in FIG.

In step S83, it is checked whether it has already been stored. If already stored (Yes), the process proceeds to step S85, and if not stored (No), the process proceeds to step S84.
In step S84, the isolation-alarm relation DB 211 stores
(1) The alarm signal names match.
(2) The IBD sheet numbers match.
(3) The IBD sheet number is close to that already stored.
Store in the order of priority. That is, when storing, a new term is not simply added to the end of the list, but is added while rearranging so that it can be easily searched visually from the alarm signal name or the IBD sheet No.

  In step S85, it is checked whether there are any items that have not yet been processed in the new quarantine-alarm association list 140 read in step S81. If an unprocessed item remains (Yes), the process returns to step S82 to repeat the process for the next item. If there is no item that has not been processed (No), the storage process of the read quarantine-alarm association list 140 is terminated, and the read quarantine-alarm association list 140 is erased from the temporary storage.

  Thus, the process of storing the isolation-alarm association list 140 shown in FIG. 22 in the isolation-alarm relation DB 211 is completed.

《Failure alarm cause search》
Next, referring to FIG. 21 and FIG. 23 to FIG. 25, the customer's central control room engineer or the customer maintenance management department engineer uses the central control room terminal device 4 or the management terminal device 7 to search for the cause of the failure alarm. A method for quickly searching for a device causing an alarm signal based on an alarm signal name or the like by the server computer 600, or for quickly searching a range of devices considered to be related to the cause of the alarm signal will be described.
FIG. 23 to FIG. 25 are flowcharts showing the flow of control for searching for the cause device of the alarm signal generation using the isolation-alarm relation DB and the drawing DB in the failure alarm cause search server computer.

In step S91, the failure alarm cause search server computer 600 checks whether or not the customer staff from the terminal devices 4 and 7 has received access to the failure alarm cause search server computer 600. If access is received (Yes), the process proceeds to step S92. If not (No), step S91 is repeated.
In step S92, the alarm signal name (symbol display) displayed on the display device (in the legend 137 of FIG. 13, "RAL0295-24" corresponds) and the alarm signal name (symbol display) are displayed. The software logic diagram sheet No. (in the legend 137 of FIG. 13, “RAL 4077” corresponds) is input.

  The alarm signal name (symbol display) and the soft logic diagram sheet No. displayed on the display device are displayed on the display device of the console of the central control room in the case of a main or important alarm signal. However, in the case of an auxiliary alarm signal name (symbol display), the display device of the console in the central control room displays only a display indicating that an alarm has been issued on the control panel, and the operator receives it. Or the engineer can go to see the display device of the control panel, and from the status display of the display device of the control panel, the alarm signal name (sign display) and the soft logic diagram sheet No. on which it is described can be seen .

In step S93, the isolation-alarm association list 140 (see FIG. 21) stored in the isolation-alarm relation DB 211 is searched based on the input alarm signal name (sign display).
In step S94, it is checked whether or not there is an input alarm signal name (sign indication) in the isolation-alarm association list 140. If there is an input alarm signal name (sign display) (Yes), the process proceeds to step S95, and if not (No), the process proceeds to step S97.
In step S95, the term of the isolation-alarm association list 140 including the alarm signal name (sign display) is displayed on the display devices of the terminal devices 4 and 7.

  In step S96, the ECWD including the soft logic diagram, the PI / O table diagram, and the alarm signal name (symbol display) included in the item of the displayed isolation-alarm association list 140 is displayed on the display devices of the terminal devices 4 and 7. The alarm signal name (sign display) is displayed in a different color. By this color change display, the operator of the terminal devices 4 and 7 can easily find the attention point of the soft logic diagram, PI / O table diagram, and ECWD.

By the way, the PI / O table diagram sheet No. is easily found in the quarantine-alarm association list 140 because the PI / O table diagram sheet No is described. The attribute information C, D, and E (see FIG. 4) for searching the respective drawings of the ECWD information 203c, the soft logic diagram information 203d, and the PI / O table diagram information 203e in FIG. Therefore, it can be easily searched and displayed by the function of the book / drawing DB search unit 244A (omitted in FIG. 1) of the failure alarm cause search server computer 600.
After step S96, the process proceeds to step S103 in FIG. 24 according to the connector (J).

In step S97, it is checked whether or not the input soft logic diagram sheet No. exists in the quarantine-alarm association list 140. If there is a soft logic diagram sheet No. (Yes), the process proceeds to step S98, and if not (No), the process proceeds to step S108 in FIG. 25 according to the connector (K).
In step S98, the term of the isolation-alarm association list 140 including the soft logic diagram sheet No. is displayed on the display devices of the terminal devices 4 and 7. Thereafter, the process proceeds to step S99 in FIG. 24 according to the connector (L).

In step S99, the soft logic diagram is displayed on the display devices of the terminal devices 4 and 7, and the input alarm signal name (sign display) is searched on the drawing.
In step S100, it is checked whether or not there is an input alarm signal name (sign display). If yes (Yes), the process proceeds to step S101. If not (No), the process proceeds to FIG. 25 according to the connector (K). The process proceeds to step S108.
In step S101, the input alarm signal name (sign display) on the soft logic diagram is displayed in a different color.
In step S102, the PI / O table diagram and ECWD including the input alarm signal name (symbol display) are displayed on the display devices of the terminal devices 4 and 7, and the alarm signal name (symbol display) is displayed on these drawings. Change color and display.

  By the display of step S95 or the display of step S98, the alarm signal name (symbol display) input by the single or plural items in the serial number column 141 searched and displayed in the isolation-alarm association list 140 of FIG. Which system name (see column 142) is associated with which device (see column 143) is related, whether it is a main device or a slave device during inspection and maintenance work (see column 145), and related main device ( Column 146), and the sheet number (see column 147) of the drawing in which the device is described. Therefore, it is quickly understood that the alarm is related to this device.

Engineers with deep experience in searching drawings of upstream design books such as system diagram (P & ID), single-line diagram, IBD, etc., but not so proficient in searching drawings of ECWD, soft logic diagrams, PI / O table diagrams However, ECWD, soft logic diagrams, and PI / O table diagrams can be quickly searched from IBD alarm signal names. Further, when determining which of the detailed devices such as which controller in the control panel is the cause, it is necessary to further search the drawing DB 203C.
For this purpose, on this screen, “Continue Survey” and “End” icon buttons are displayed on this screen for inputting whether further detailed survey is to be continued or terminated.

In step S103, it is checked whether or not a more detailed investigation is to be performed. If the “Continue Survey” icon button is operated (Yes), the process proceeds to step S104, and if the “End” icon button is operated (No), the process ends.
In step S104, designation of an upstream signal name (symbol display) is accepted on the displayed soft logic diagram.

  In step S105, the software logic diagram, PI / O table diagram, and ECWD including the designated signal name (symbol display) are displayed, and the designated signal name (symbol display) is displayed in a different color. This color change display makes it easy to find further signal names (symbol display) or other signal names (symbol display) input to various logic patterns such as an AND logic pattern and an OR logic pattern. In this screen state, “Continue Survey” and “End” icon buttons are displayed on this screen for inputting whether further detailed survey is to be continued or terminated.

In step S106, it is checked whether or not to conduct a more detailed investigation. If the “Continue Survey” icon button is operated (Yes), the process proceeds to step S107, and if the “End” icon button is operated (No), the process ends.
In step S107, designation of any of the plurality of displayed soft logic diagrams is accepted. This designation can be performed, for example, by moving the arrow indication mark to a white background portion on the target soft logic diagram by a mouse operation and performing a double click operation in that state.
Thereafter, the process returns to step S104.

When the process proceeds from step S97 or step S100 to step S108 according to the connector (K), based on the input alarm signal name (symbol display), the IBD including the alarm signal name (symbol display) from the drawing DB 203C, soft logic The figure, PI / O table diagram, and ECWD are displayed on the display devices of the terminal devices 4 and 7, and the input alarm signal name (symbol display) is displayed in different colors on each drawing. Thereafter, the process proceeds to step S109 to display the system name.
There are IBD information 203f systematic names in the figures of the column (IBD (drawing 203f ₁ displays the alarm output) of the FIG. 13 IBD information 203f) 131 (see FIG. 13), the input alarm signal name (code display ) System name can be easily searched and displayed.
After step S109, the process proceeds to step S103 in FIG. 24 according to the connector (M).
This completes the process of quickly searching for a device that is the cause of the alarm signal based on the name of the alarm signal or the like, or quickly searching for the range of devices that are considered to be related to the cause of the alarm signal.
