Description

  Embodiments described herein relate generally to a resource management system and a resource management method.

  In existing nuclear power plants, accident conditions may develop rapidly. In such a case, it is difficult to perform a recovery operation after determining a more appropriate response means using the collected information. For this reason, when a serious accident occurs, a great deal of labor is required for the recovery work. For example, there are cases where operators and plant instructors require labor to grasp on-site information and work progress, and there is a case where necessary information cannot be shared among related parties. There is a risk that it will not be possible to make a quick understanding and appropriate decision on the response policy. For this reason, there is a need for a monitoring and display system that supports prompt and reliable recognition of plant abnormality in the event of a plant abnormality and can share necessary information among related parties.

  In particular, in order to recover an abnormal situation due to a failure of equipment or equipment, under the consistent management based on the response plan by the plant instructor, the necessary replacement parts, the work time required to replace the replacement parts, and the workers It is necessary to quickly grasp the above and formulate a recovery work plan.

  In addition, technologies related to a mechanism related to resource management for process management are disclosed. However, this mechanism is a technique for carrying out regular periodic inspections more systematically, and does not assume a situation in which a prompt response is required as in an accident.

  In an existing nuclear power plant, when an abnormal event occurs due to a faulty part such as a failed device, the discoverer, the instructor who gives a restoration instruction, the maintenance staff who gives the worker a work instruction, the worker who performs on-site work, etc. Correspondence is performed by such. However, when this measure is taken, in addition to the human task of communicating and reporting between personnel, there are tasks such as confirmation work for finding replacement candidate articles for the failed part, and securing and arranging work personnel. Yes. In this case, it takes time to deal with the communication between the parties concerned and deal with the work. Furthermore, there is no mechanism for monitoring the progress of the entire response plan for an abnormal event, and it is difficult to confirm the progress status of the response plan and to share this progress status among related parties.

For this reason, in order to maintain the function of the plant, it is necessary to deal with a plurality of abnormal events. However, it is said that the response by the existing system places a lot of human load on the determination of the priority order for a plurality of abnormal events, the formulation of a recovery plan, and the work of collecting information. In particular, in the case of an abnormal event that occurs due to a faulty part, it is difficult to secure sufficient replacement articles for restoring the function. For this reason, in order to maintain the plant operation plan, a flexible response is required in which an item in another facility that is normally operating is used as a replacement item for the failed part.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
The resource management system according to the first embodiment sorts the articles that can be used for recovery of the faulty part based on the function priority according to the plant state, thereby replacing the articles arranged in the order of the function priority. A correspondence plan table is formed as an article so that replacement candidate articles can be provided more appropriately. More details will be described below.

  Based on FIG. 1 thru | or FIG. 3, the whole structure of the resource management system 1 which concerns on 1st Embodiment is demonstrated. FIG. 1 is a block diagram illustrating the configuration of the resource management system 1 according to the first embodiment. As shown in FIG. 1, the resource management system 1 according to this embodiment includes a resource adjustment unit 100, a plant database 120, an equipment specification database 140, and a resource management database 160.

  The resource adjustment unit 100 supports plant maintenance work. In the present embodiment, the resource adjustment unit 100 includes a plan management unit (input unit) 180A, a similar specification extraction unit 200, an abnormal stage determination unit 220, an article detection unit 240, and a plan management unit (output unit). 180B, which will be described later in detail.

  In the plant database 120, plant parameters relating to plant state changes, alarm messages based on the plant parameters, and the like are recorded as plant state information in chronological order.

  The facility specification database 140 includes specifications corresponding to each of the articles in the plant, function priorities according to the abnormal stage of the plant for each of these articles, and information on specifications used with priority when searching for similar articles. It is recorded. This function priority indicates the priority of maintaining the function of the plant.

  Moreover, the abnormal stage of the plant as the plant state is classified into, for example, a design base accident DBA (Design Base Accident), severe accidents SA1, SA2, and the like. That is, this abnormal stage is classified into four levels, such as DBA, SA1, SA2, and after the functional container is damaged, from the lighter degree of damage. The detailed configuration of the equipment specification database 140 will be described later with reference to FIG.

  In the resource management database 160, the equipment state of articles existing in the plant is accumulated. The detailed configuration of the resource management database 160 will be described later with reference to FIG.

  The monitoring operation terminal 10 is arranged at a position where a discoverer, an instructor, a maintenance staff, a worker or the like can monitor and operate. The monitoring operation terminal 10 is a personal computer, for example.

  The plan management unit (input unit) 180A in the resource adjustment unit 100 described above reads information output from the monitoring operation terminal 10 used by each of the discoverer, the instructor, the maintenance staff, the worker, and the like. That is, the plan management unit (input unit) 180A performs a process for forming a plan management screen having a response plan table for an abnormal event and an input process to the response plan table according to the input information. For example, the plan management unit (input unit) 180A reads from the monitoring operation terminal 10 the date and time of occurrence, the abnormal item of the abnormality that has occurred, the content of the abnormality that has occurred, the failure part, the work plan, and the like. Is.

  The similar specification extracting unit 200 is an article that can be used for recovery of the failed part input in the correspondence plan table, and extracts an article having the same specification and similar specification as the failed part. That is, the similar specification extraction unit 200 extracts a replacement candidate article that can be used for recovery of the failed part from the equipment specification database 140 that stores specifications corresponding to each article in the plant based on the specification of the failed part. For example, these articles are extracted as a replacement article list including alternative means.

  The abnormal stage determination unit 220 uses the plant state information recorded in the plant database 120 to determine the abnormal stage of the plant as the plant state. The abnormal stage determination unit 220 obtains, from the equipment specification database 140, a function priority according to the plant state for each usable article extracted by the similar specification extraction unit 200 based on the abnormal stage of the plant. It is.

  The article detection unit 240 sorts each usable article extracted by the similar specification extraction unit 200 according to the corresponding function priority. That is, the article detection unit 240 detects and outputs information on these usable articles arranged in the sort order as a detection result. In this case, the article detection unit 240 outputs an article provided in another correspondence plan table by removing it from the detection result.

  Based on the detection result, the plan management unit (output unit) 180B forms a correspondence plan table in which these usable articles arranged in the sort order are used as replacement candidate articles for the failure part. In addition, the plan management unit (output unit) 180B outputs a plan management screen having the formed correspondence plan table so that it can be displayed on the monitoring operation terminal 10. That is, the plan management unit (output unit) 180B outputs the plan management screen having the correspondence plan table and the plan management screen having the correspondence plan table so that they can be displayed on the monitoring operation terminal 10. In the present embodiment, the plan management unit (input unit) 180A and the plan management unit (output unit) 180B constitute a plan management unit.

  Next, data stored in the facility specification database 140 will be described with reference to FIG. FIG. 2 is a diagram showing data stored in the facility specification database 140. As shown in FIG. 2, the equipment specification database 140 stores article specification data 12, function priority data 14, and similarity priority determination data 16.

  The item specification data 12 records N specifications indicating the device name, TAGNO, device system, and device characteristics for all devices forming the plant. In the present embodiment, the device may be referred to as an article. This device is, for example, a control panel, a power panel, a battery, a valve, a board, or the like.

  In the function priority data 14, the function priority corresponding to the plant state is recorded in advance for all the articles recorded in the article specification data 12. As the function priority, for example, when the abnormal stage level of the plant is DBA, 1 is assigned to the equipment used in the plant, while in the case of DBA, the equipment is less likely to be used in the plant. Is assigned 0. That is, 0 is assigned to an article that can be used for replacement of a failed part, and 1 is assigned to an article that is difficult to use for replacement.

  Further, in the case of SA1 in which the degree of damage to the plant is increased by one step, the equipment used in the plant is different from that in the case of DBA. For example, since the power panel B is used for plant control at the DBA stage, 1 is assigned as the function priority. However, at the SA1 stage, since the possibility of being used for plant control is low, 0 is assigned as the function priority. Furthermore, after the specific container damage in which the degree of damage to the plant has become heavy, 1 is assigned as the function priority to the equipment related to the water discharge vehicle that has been assigned 0 until the stage of SA2. Note that the function priority may be multi-valued according to the priority level. For example, 0, 1, 2, 3, etc. may be assigned to the function priority.

  In the similarity priority determination data 16, information on the specifications prioritized for the device system in the article specification data 12 is recorded as a priority key. That is, in the function priority data 14, the order of specifications prioritized during the similarity determination process is recorded in association with the equipment system in the article specification data 12.

  Next, data stored in the resource management database 160 will be described with reference to FIG. FIG. 3 is a diagram illustrating data stored in the resource management database 160. As shown in FIG. 3, the resource management database 160 stores equipment state management data 18.

  The equipment state management data 18 is data for managing the equipment state of the articles existing in the plant, and the plan number assigned to the corresponding plan table is assigned to the article selected from the replacement candidate articles. It is. That is, the plan number assigned to the correspondence plan table that has not been completed is assigned as the correspondence plan number. In addition, the equipment state management data 18 includes the inspection state of all items existing in the plant, the previous inspection date, the accumulated operation time accumulated from the installation of the item, the state of charge of the battery and the state of the equipment. The planned remaining operation time such as the continuous operation guarantee time and the arrangement position when the event occurs are recorded.

  The above is the description of the overall configuration of the overall configuration of the resource management system 1 according to the present embodiment. Next, the processing operation of the resource adjustment unit 100 that outputs the replacement candidate article will be described based on FIG. FIG. 4 is a flowchart for explaining the flow of processing operations for providing exchange candidate articles performed by the resource adjustment unit 100.

  Here, when the maintenance staff inputs the failure part to the input unit via the monitoring operation terminal 10, the replacement candidate article list of the failure part is repaired via the plan management screen having the correspondence plan table corresponding to the failure part. Explain the example provided to the staff.

  As shown in FIG. 4, the failure part is input to the correspondence plan table from the monitoring operation terminal 10 operated by the maintenance staff through the plan management unit (input unit) 180A (step S10). Next, the abnormal stage determination unit 220 reads plant parameters for determining an abnormal stage from the plant database 120 (step S12). Subsequently, the abnormal stage determination unit 220 determines the abnormal stage of the plant based on the plant parameter, reads the function priority data 14 from the equipment specification database 140, and extracts the function priority according to the plant abnormal stage. . (Step S14).

  Next, the similar specification extraction unit 200 reads the article specification data 12 and the similarity priority determination data 12 from the equipment specification database (step S16). Subsequently, the similar specification extraction unit 200 extracts an article having the same specification as the failed part and a similar article serving as a substitute for the failed part as an article that can be used to recover the failed part (step S18). That is, the similar specification extraction unit 200 uses the specification information recorded in the priority key in the similarity priority determination data associated with the equipment system of the article corresponding to the failure part, from the article specification data 12 to the similar article. To extract. Subsequently, the similar specification extraction unit 200 outputs the detection result to the article detection unit 240.

  Next, the article detection unit 240 reads the function priority of each article that can be used for recovery of the failed part from the function priorities according to the plant abnormality stage extracted by the abnormality stage determination unit 220 (step S20). . Subsequently, the article detection unit 240 sorts these usable articles using the read function priority (step S22). Subsequently, the article detection unit 240 reads management data regarding these usable articles from the resource management database 160 (step S24).

  Next, based on the management data that has been read, the article detection unit 240 determines whether these usable articles are duplicated with other correspondence plan tables (step S26). In other words, it is confirmed whether there is an article that is assigned a number corresponding to another correspondence plan table among these usable articles, and an article that is assigned a number corresponding to another correspondence plan table. Judge that it overlaps with other plans.

  Subsequently, the article detection unit 240 removes the articles determined to be duplicated from the usable articles arranged in the sort order, and uses the information on these usable articles arranged in the sort order as a detection result as a plan management unit (output unit). ) Output to 180B (step S28). That is, the article detection unit 240 outputs usable article information and the function priority of each usable article to the plan management unit (output unit) 180B, excluding duplicated articles.

  Next, the plan management unit (output unit) 180B forms a correspondence plan table with usable articles arranged in the sort order as replacement candidate articles for the failure part, and the maintenance staff operates the plan management screen having this correspondence plan table. Displayed on the monitoring operation terminal 10 to be displayed. The maintenance staff determines a replacement device from the correspondence plan table and ends the process (step S30). In this way, it is possible to determine whether or not there is an overlapping assignment with another corresponding plan table for the result of the sorting process, and to provide the replacement candidate article list to the maintenance staff via the plan management screen having the corresponding plan table. .

  Next, the flow of the abnormal stage determination process performed by the abnormal stage determination unit 220 will be described with reference to FIG. FIG. 5 is a flowchart showing the flow of the abnormal stage determination process performed by the abnormal stage determination unit 220. Here, an example will be described in which, when the maintenance staff inputs a failure part to the plan management unit (input unit) 180A via the monitoring operation terminal 10, the function priority for the replacement candidate article of the failure part is extracted.

  As shown in FIG. 5, the maintenance staff inputs the failed part to the plan management unit (input unit) 180A via the monitoring operation terminal 10 (step S40). Next, the abnormal stage determination unit 220 reads the failure part from the plan management unit (input unit) 180A (step S42). Subsequently, the abnormal stage determination unit 220 reads the latest plant parameters from the plant database 120 (step S44).

  Next, the abnormal stage determination unit 220 determines which abnormal stage the plant state corresponds to according to a conditional expression set in advance by the instructor using the read plant parameters (step S46). For example, if one plant parameter indicates “DC main bus board A: power loss” and the other parameter indicates “DC main bus board B: power loss”, the set condition SA1 is determined according to the equation. Further, for example, when the read parameter indicates “EHPCCW operation”, it is determined as SA2 in accordance with the set conditional expression. This abnormal stage is sometimes called an accident response level.

  The maintenance staff can also input the plant state via the plan management unit (input unit) 180A. That is, when it is desired to change the plant state, the maintenance staff inputs the abnormal state at the plant state via the plan management unit (input unit) 180A (step S48).

  Next, the abnormal stage determination unit 220 determines whether a plant state input operation is performed (step S50). When the maintenance staff is performing an input operation (step S50: Yes), the automatic determination processing result is changed to the plant state input by the input operation (step S52). On the other hand, when the maintenance staff has not performed an input operation (step S50: No), and after the above-described step S52, the function priority data is read from the equipment specification database 140 (step S54).

  Next, the function priority corresponding to the determined plant state is extracted for the article that can be used for recovery of the failed part (step S56). The extracted function priority and the determined plant state are output to the article detection unit 240, and the abnormal stage determination process is terminated (step S58). Thereby, it becomes possible to extract the priority of these usable articles according to the plant state and to quickly reflect it in the recovery plan formulation. Note that the information on the usable articles may be input from the similar specification extraction unit 200 to the abnormal stage determination unit 220 or may be input to the abnormal stage determination unit 220 via the article detection unit 240. Further, when the information on the usable articles is not input to the abnormal stage determination unit 220, the function priorities for all the articles may be output to the article detection unit 240.

  Next, the flow of the similar specification extraction process of the article performed by the similar specification extraction unit 200 will be described with reference to FIG. FIG. 6 is a flowchart showing a flow of similar specification extraction processing for an article performed by the similar specification extraction unit 200. Here, an example will be described in which, when the maintenance staff inputs a failure part to the plan management unit (input unit) 180A via the monitoring operation terminal 10, an article that can be used for recovery of the failure part is extracted.

  As shown in FIG. 6, the similar specification extraction unit 200 reads the failure part from the plan management unit (input unit) 180A (step S60). Subsequently, the similar specification extraction unit 200 reads the article specification data 12 and the similarity priority determination data 16 from the equipment specification database 140 (step S62).

  Next, the similar specification extraction unit 200 calculates the compatibility between the article corresponding to the failure part and the article recorded in the article specification data 12 (step S64). In other words, the similar specification extraction unit 200 acquires information on the equipment system recorded in the article specification data 12 for the article corresponding to the failed part, and assigns priority information to the priority key associated with the equipment system. Obtained from degree determination data. Subsequently, an article having the specification described in the priority key is extracted from the article specification data 12, and a calculation for converting the compatibility into a numerical value is performed based on the matching state with the priority key. For example, 2 points are added if the specification of the article matches the priority key 1, and 1.7 points are added if it matches the priority key 2, and the points assigned to the appropriate priority key are added. Quantify compatibility.

  Next, the similar specification extraction unit 200 performs the sorting process of the articles based on the numerical value allocated for each article (Step S66). That is, the similar specification extraction unit 200 extracts an article having a numerical value greater than or equal to a certain value based on the result of the sorting process as an article having a high compatibility value. Subsequently, the similar specification extraction unit 200 lists the extracted articles having the same specification and similar specifications, and outputs them to the detection unit as articles that can be used for recovery of the faulty part, and ends the similar specification extraction process ( Step S68). As a result, even if there are no parts in the plant that have exactly the same specifications as the part at the failure site, an article that has a certain level of compatibility is automatically extracted as an alternative, and information is provided to relevant parties including maintenance staff. can do.

  Next, the flow of processing performed by the article detection unit 240 will be described based on FIG. FIG. 7 is a flowchart for explaining the flow of processing performed by the article detection unit 240. Here, an example will be described in which the extraction of articles that can be used for recovery of a faulty part and the extraction of function priorities have already been completed.

  As shown in FIG. 7, first, the article detection unit 240 reads the extraction result regarding the function priority from the abnormal stage determination unit 220, and the similar specification extraction unit 200 reads the article having the same specification as the failure part and the similar specification. The article is read as an article that can be used to recover the failed part (step S70). Subsequently, the article detection unit 240 sorts these usable articles by the corresponding function priority (step S72). That is, the article detection unit 240 arranges the usable articles in ascending order of function priority values.

  Next, the article detection unit 240 reads the equipment state management data 18 from the resource management database 160 (step S74). Subsequently, the article detection unit 240 associates the sorted usable articles with the equipment state management data 18 (step S76).

  Next, the article detection unit 240 determines whether or not the plan management number is assigned to an available article in the equipment state management data 18 during the associating process (step S78). When assigned (step S78: Yes), the article detection unit 240 excludes an article to which a plan management number is assigned from available articles (step S80).

  On the other hand, when the plan management number is not assigned (step S78: No), after the above-described step S80, the article detection unit 240 performs plan management using information on usable articles arranged in the sort order as a detection result. Output to the unit (output unit) 180B, and the process performed by the article detection unit 240 is terminated (step S82).

  This makes it possible to extract articles that can be used for replacement work from all the articles managed in the plant with respect to the failed part. For this reason, for example, it is possible to eliminate the manual extraction work that is performed in the conventional work procedure, such as extracting a replaceable exchange article while referring to the specifications on the design book. Furthermore, it is avoided that the replacement items selected in the other corresponding plan table in parallel are selected redundantly. As described above, by operating the monitoring operation terminal 10, it is possible to automatically display an article list reflecting the function priority according to the plant state based on the failure part input in the correspondence plan table. As a result, the time required for searching for replacement candidate articles can be shortened.

  As described above, according to the resource management system 1 according to the present embodiment, the article detection unit 240 sorts the articles that can be used for recovery of the faulty part by the function priority according to the plant state, and the plan management unit. It is decided to form a correspondence plan table in which articles usable for restoration arranged in order of function priority 180 are exchange candidate articles. Thereby, exchange candidate goods can be provided more appropriately.

(Second Embodiment)
The resource management system according to the second embodiment allocates a plan number by allocating a plan number in the corresponding plan table to the selected item when an item is selected from the replacement candidate items in the corresponding plan table. It is intended to prevent the replacement candidate article from being redundantly provided to each of the different response plan tables by providing the unrecognized items as replacement candidate items in other different response plan tables. Hereinafter, a different part from 1st Embodiment mentioned above is demonstrated.

  FIG. 8 is a block diagram illustrating the configuration of the resource management system 1 according to the second embodiment. As shown in FIG. 8, the resource management system 1 according to this embodiment is different from the resource management system 1 according to the first embodiment in that a resource plan management database 260 is provided instead of the resource management database 160. doing.

  Next, data stored in the resource plan management database 260 will be described with reference to FIG. FIG. 9 is a diagram for explaining data accumulated in the resource plan management database 260. As shown in FIG. 9, the resource plan management database 260 stores equipment state management data 18, terminal operation history data 22, and abnormality occurrence history data 24. The equipment state management data 18 is equivalent to the equipment state management data 18 included in the resource management database 160. That is, the equipment state management data 18 is data for managing the equipment state of the articles existing in the plant, and is the plan number assigned to the correspondence plan table for the article selected from the replacement candidate articles. Is allocated.

  In the terminal operation history data 22, operation contents and operation execution times from a plurality of monitoring operation terminals 10 installed in various places to the plan management unit (input unit) 180 </ b> A are recorded in chronological order as history. Further, the abnormality occurrence history data 24 is equivalent to the data recorded in the plant database 120. That is, in the abnormality occurrence history data 24, plant parameters relating to plant state changes and alarm messages based on the plant parameters are recorded in chronological order.

  Next, a process of automatically reflecting the plan number assigned to the correspondence plan table on the articles in the equipment state management data 18 will be described with reference to FIG. FIG. 10 is a flowchart for explaining the flow of processing for automatically reflecting the plan number assigned to the correspondence plan table to the articles in the equipment state management data 18. Here, an example will be described in which the maintenance staff operates the monitoring operation terminal 10 to select an article to be used for recovery work from among replacement candidate articles for the failed article.

  As shown in FIG. 10, the maintenance staff operates the monitoring operation terminal 10 to select an article to be used for the restoration work from the replacement candidate articles (step S90). Subsequently, the plan management unit (input unit) 180A reads the selected replacement target article (step S92).

  Next, the plan management unit (input unit) 180A reflects the plan number of the corresponding plan table corresponding to the selected replacement target article in the equipment state management data 18 of the resource plan management database 260, and ends the process (step). S94). That is, the plan management unit (input unit) 180 </ b> A reflects the plan number corresponding to the correspondence plan table on which the maintenance staff performs an operation of selecting an article in the equipment state management data 18. In this manner, the equipment state management data 18 is automatically updated without the maintenance staff operating the monitoring operation terminal 10 to update the equipment state management data 18. In addition, the article detection unit 240 can output information on articles that can be used for recovery of a failed part to which no plan number is assigned based on the updated equipment state management data 18. As a result, it is avoided that the plan management unit (output unit) 180B redundantly provides replacement candidate articles to different correspondence plan tables.

  Further, the plan management unit (output unit) 180B supports the formulation of a similar correspondence plan table based on the operation history in the terminal operation history data 22 and the abnormality occurrence history in the abnormality occurrence history data 24, and the prepared correspondence plan table Outputs information that enables support for corrections.

  For example, when the maintenance staff or the like operates the monitoring operation terminal 10 and characters such as “control panel A” are input to the abnormal items in the correspondence plan table, the plan management unit “ An operation history similar to “control panel A” is searched. Subsequently, the plan management unit (input unit) 180A searches the abnormality occurrence history data 24 for a plant parameter corresponding to the occurrence time of the operation history similar to the searched “control panel A”. Subsequently, the plan management unit further re-searches plant parameters similar to the current plant parameters from the searched plant parameters. Then, the plan management unit displays the correspondence plan table corresponding to the re-searched plant parameter on the monitoring operation terminal 10 as a reference.

  That is, the plan management unit (input unit) 180A is a correspondence plan table in which characters similar to “control panel A” are inputted from among correspondence plan tables formed in the past, and similar plant parameters are generated. Search the correspondence plan table in the state that has been checked and display it for reference. In this case, there is a high possibility that a response plan table for an abnormal event similar to the current abnormal event is displayed. For this reason, the maintenance staff can formulate the response plan table and revise the prepared response plan table with reference to the contents described in the response plan table displayed for reference.

  As described above, according to the resource management system 1 according to the present embodiment, the plan management unit (input unit) 180A displays the plan number in the equipment state management data 18 when an item is selected from the replacement candidate items. And the article detection unit 240 based on the equipment state management data 18, the article to which the plan number is not assigned is sent to the plan management unit (output unit) 180 B as an article that can be used for recovery of the failed part. I decided to output it. Thereby, it can avoid that the plan management part (output part) 180B provides an exchange candidate article redundantly to each different correspondence plan table | surface.

(Third embodiment)
In the resource management system according to the third embodiment, information is input to a response plan table from a plurality of monitoring operation terminals, and the response plan table in which the information is input is output so as to be displayed on a plurality of monitoring operation terminals. It is intended to more appropriately share information among concerned parties. Hereinafter, a different part from 2nd Embodiment mentioned above is demonstrated.

  FIG. 11 is a block diagram illustrating the configuration of the resource management system 1 according to the third embodiment. As shown in FIG. 11, the resource management system 1 according to this embodiment is different from the resource management system 1 according to the second embodiment in that it further includes a sensor 26 and an alarm device 28. The sensor 26 outputs plant parameters to the plant database 120. The alarm device 28 receives plant parameters from the sensor 26, generates a warning message based on the plant parameters, and outputs the warning message to the plant database 120.

  The monitoring operation terminal 10 is installed at a position where each of the discoverer, the instructor, the maintenance staff, and the operator can monitor and operate. Thus, the correspondence is notified from the resource adjustment unit 100 to the discoverer, the instructor, the maintenance staff, and the worker via the monitoring operation terminal 10. That is, information is inputted to the correspondence plan table from the plurality of monitoring operation terminals 10 via the plan management unit (input unit) 180A, and the correspondence plan table to which the information is inputted is sent to the plan management unit (output unit) 180B. And output to the plurality of monitoring operation terminals 10 through the display.

  Next, the correspondence plan table will be described with reference to FIG. FIG. 12 is an example of a correspondence plan table. As shown in FIG. 12, the correspondence plan table is configured with a description column divided for each plan number. That is, each column corresponds to an individual response plan table. In addition, each column, that is, each of the correspondence plan table includes a plan number, an occurrence date, an abnormal item, an abnormal content, an associated alarm, a treatment deadline, an impact assessment, a failure part, a replacement candidate article, a management state, a current position, a work plan, It consists of input items for schedule, work progress, and confirmation result. Also, the plan management unit (input unit) 180A assigns a plan number to the item of the plan number when information is newly input to any item of the correspondence plan table.

  In addition, the occurrence date and time of the abnormal event is input as the occurrence date and time, the item of the generated abnormality is input to the abnormal item, and the detailed content of the abnormality is input to the abnormal content. Further, a related alarm message fetched from the abnormality occurrence history data 24 in the plant design database 8 can be input to the related alarm as a reference.

  Furthermore, the deadline in which the instructor compared with the plant operation procedure and the like is input as the treatment deadline, and the influence on the plant operation and function maintenance accompanying the occurrence of abnormality is input by the maintenance staff in the impact evaluation. In the exchange candidate articles, the exchange candidate articles extracted by the article detection unit 240 are listed and displayed.

  Moreover, the information regarding the management state in the equipment state management data 18 is input into the management state with respect to the article displayed as the replacement candidate article. For example, in the case of a battery, the charging time, that is, the remaining working time or the like is input as the management state. In the current position, the arrangement position in the plant that is taken in for the replacement candidate article from the equipment state management data 18 is displayed. In the work plan, the work place, the target equipment, the target article, the required number of people, and the work procedure are input by the maintenance staff as work instructions from the maintenance staff. In the work schedule, the work start scheduled time and the work completion scheduled time are input by the worker based on the work instruction from the maintenance staff. The work progress and the work completion report are input to the work progress by the maintenance staff or the worker. In the result confirmation, information indicating that the restoration at the event occurrence point has been confirmed is input by the instructor or the discoverer.

  In this way, there is no authority or restriction for input work to the response plan table, and confirmation and input operations can be performed on the same response plan table from any monitoring operation terminal 10. Further, the history of input operations to the correspondence plan table is accumulated in the resource plan management database 260 as terminal operation history data 22 in chronological order. This operation history can be confirmed on the monitoring operation terminal 10 via the plan management unit (output unit) 180B in the resource adjustment unit 100 separately from the correspondence plan table.

  Further, the response plan table has a function of notifying a target person who wants to request the next response after the related person performs necessary input work. For example, the plan management unit (output unit) 180B, based on the terminal operation history data 22 stored in the resource management database 160, where information has been changed in the items of the correspondence plan table, or where the items have been input To extract. Subsequently, the plan management unit (output unit) 180B emphasizes these items by color change or the like, and notifies the corresponding person in an identifiable state.

In this case, the discoverer performs input processing on the occurrence date and time, the abnormal item, the abnormal content, the related alarm, and the confirmation item. That is, the discoverer discovers an event, reports an abnormal event to the instructor, confirms an event after recovery, and reports a confirmation result to the instructor.

  In addition, the instructor performs input processing for the treatment deadline and the confirmation result items. That is, the instructor performs necessity of handling an abnormal event, judgment of setting of a handling level in an accident state, setting of a treatment deadline, and a handling instruction to a maintenance staff. The response level in this accident state is usually a serious accident.

  Furthermore, the maintenance staff performs input processing for impact assessment, failure location, work plan, and work progress. In other words, the maintenance staff evaluates the impact on the plant for abnormal events, formulates a work plan until event recovery, arranges items and personnel, manages the recovery work on the site, manages items such as replacement parts and portable equipment, Deliver.

  The worker performs an input process to the work schedule and work progress. That is, the worker reports the scheduled work time, the recovery work, and the work result.
