Description

  The present invention relates to a process management method, and more particularly, to a process management system having an isolation management function for performing isolation management and a method thereof.

  In general, it is known that a process management system and an isolation management system exist and function independently in maintenance work of a large plant such as a nuclear power plant (see, for example, Patent Document 1).

  The process management system and the isolation management system in this nuclear power plant will be described below. At a nuclear power plant, maintenance work is regularly performed in order to generate power safely. This maintenance work is a wide range of maintenance work items such as equipment inspection, repair, replacement of deteriorated parts, etc. (One maintenance work item is a series of maintenance work closely related to each other for one maintenance purpose. The maintenance work related to is performed. In general, these maintenance operations need to be completed within a certain period of time when the plant is stopped, and therefore, a plurality of maintenance operations are performed in a complicated manner. In addition, each maintenance operation must be performed in a certain order, that is, other maintenance operations must be completed before one maintenance operation, and safety is ensured before the operation starts. Certain preparations must be completed for etc.

  Under the circumstances described above, in order to carry out maintenance work on a nuclear power plant or the like, a maintenance work plan is made in advance, and the progress status of the maintenance work actually performed during the periodic inspection period is recorded and managed. Process management must be performed so that each maintenance work is performed safely and without delay. For this reason, the process control system of the plant which used the computer conventionally was used.

  Here, conventional process management means and isolation management means will be described with reference to FIGS. FIG. 12 is a configuration diagram showing the configuration of the conventional process management means, and FIG. 13 is a configuration diagram showing the configuration of the conventional isolation management means.

  As shown in FIG. 12, the conventional process management system 31 includes a process editing unit 32, a process attribute editing unit 33, a time analysis unit 34, a process display unit 35, and a graph display unit 36. . In the process editing unit 32, the maintenance work execution period and the context between the works are input. There are a type in which a process is created graphically using a pointing device such as a mouse, and a type in which a process is created using numerical (symbol) information. The process attribute editing unit 33 edits process attribute information such as the maintenance work name, the name of the company in charge of the work, the supervisory department name of the electric power company, or resource information such as the actual / planned artificial number.

  The process display unit 35 is a means for displaying the information edited and input by the process editing unit 32 and the process attribute editing unit 33 as it is or after being processed. The graph display unit 36 is a unit that displays the resource information edited by the process attribute editing unit 33 in a graph format by performing operations such as addition for each time unit in the entire process or a part thereof.

  In addition, in nuclear power plants, collaborating companies prepare books such as construction procedures, and the contents and timing of system isolation are described in them. Based on the content and timing of this system isolation, the above-mentioned power company employees have applied for isolation on a device-by-device basis. The requested quarantine documents are collected by the department in charge of the electric power company, and adjustments are made such as integrating those that can be quarantined together. Finally, fill the drawing with isolated areas to make sure there are no problems. In a general isolation management system, when a device to be constructed is designated, candidates for isolation locations necessary for the construction are extracted from past results and the like. The departments in charge of the electric power company carry out the selection from the extracted candidates for isolation and the integration of the isolations with reference to drawings and processes.

  Next, the isolation management system will be described with reference to FIG.

As shown in FIG. 13, the conventional process management system 37 includes a construction target device registration unit 38, an isolation location designation unit 39, an actual / plan input unit 40, and an isolation location display unit 41. The construction target device registration unit 38 selects a construction target device by either using a device name or a device number or selecting a device symbol using a drawing on the screen. ing. In the isolation location designating unit 39, when constructing the construction target device registered in the construction target device registration unit 38, the isolation location and the execution timing for isolation such as valve closing operation and power shut-off are designated. At this time, there is a system for extracting a candidate for an isolation part such as a power shutdown. In the actual / plan input unit 40, the scheduled time and actual time for performing isolation such as power-off are input or changed. The isolation part display unit 41 is a means for displaying the information input by the construction target device registration unit 38, the isolation part designation unit 39, and the result / plan input unit 40 as they are or after being processed.

Not.

  For example, in a process management system and an isolation management system in a nuclear power plant, in order to perform construction, it is necessary to isolate a target device and prepare in advance so that the device can be overhauled. If a large amount of this device is isolated, the operations may be complicated and confusing. In order to avoid this, the isolation work is substantially reduced by a method such as integrating the isolation points of equipment and isolating the entire line.

  However, construction is delayed, and it is required that the isolation of some target devices and the operation test of other target devices be performed at the same timing, and complicated isolation is sometimes required. In this case, it is necessary to confirm that there is no error in the isolation of the target device, etc. by painting the target device, etc. and peripheral devices on the drawing. There was a problem in that it required a lot of labor.

  In addition, since the process management system 31 and the isolation management system 37 are not linked, the isolation plan created on the isolation management system 37 must be significantly changed by the change of the work schedule generated on the process management system 31.

  Embodiments of a process management system and method having an isolation management function according to the present invention will be described below with reference to the drawings. Here, the same or similar parts are denoted by common reference numerals, and redundant description is omitted.

  FIG. 1 is a configuration diagram showing a configuration of a process management system 1 having an isolation management function according to an embodiment of the present invention.

  First, the configuration of the process management system 1 having an isolation management function will be described with reference to FIG.

  As shown in the figure, the process management system 1 having an isolation management function includes a process management unit 2, an isolation management unit 3, and an incidental unit 4. Here, “means” and “system” are a general term for computer processing devices, their input / output means, and storage means. In addition to the case where they are physically one computer, distributed computers are connected by data communication. Including the case.

  This process management means 2 is a means for inputting, displaying and storing the process plan and work results performed at the power plant. The process edit section 5, the process attribute edit section 6, the time analysis section 7, and the process display section. 8 and a graph display unit 9.

  The process editing unit 5 is configured to be able to input and edit work in chronological order, and is also configured to be able to perform linking indicating the context between the work. Enclose the work from start to finish with a symbol such as a rectangle. Linking indicating the context between the works is performed by selecting the symbol of the preceding work and then selecting the symbol of the succeeding work in the same manner.

  The process attribute editing unit 6 is configured so that resource information and remark information can be input and edited for each process. By opening the symbol for the above operation, it is possible to input, change and refer to resource information and remark information. The limit amount of resources can also be registered.

In the time analysis part 7, it implements by menu selection etc. As a technique, a PERT (Program Evaluation and Review Technique) technique is basically used. This PERT method is one of the process planning and management methods. By making the interdependencies of each work that constitutes the entire work (project), a schedule plan for each work is created and the time required for the entire work is reduced. It is a method of calculating and further clarifying the required time. The general procedure is as follows.
1. Clarify the work of each process.
2. Estimate the time required to complete each process.
3. Clarify the execution order of processes and the context between processes.
4). Each process is connected, that is, linked, and a network diagram is created (start date and end date of each process are determined).
5. Calculate the time required for the entire job and clarify the completion time.
6). Consider shortening the time required for critical paths.

  The process display unit 8 will be described with reference to FIG. FIG. 2 is a process chart showing a specific example of the screen of the process display unit 8 and the graph display unit 9 of FIG. As shown in FIG. 2, the process display unit 8 is configured to display processes in chronological order, and the process editing unit 5 and the process attribute editing unit 6 are also operated on the same screen.

  As shown in FIG. 2, the graph display unit 9 calculates resource information input to each process in synchronization with the processes displayed according to the time series (time coincidence) and displays the resource information on the graph. It is configured to be able to. In this graph display unit 9, a plurality of persons in charge of the electric power company allocated to the work are regarded as resources, and the amount per hour is displayed. In addition, it is possible to determine whether or not the limit amount has been exceeded on the screen.

  Next, the isolation management unit 3 will be described. The isolation management unit 3 includes a construction target device registration unit 10, an isolation location designation unit 11, an actual / plan input unit 12, an isolation location adjustment unit 13, and an isolation location display unit 14.

  The construction target device registration unit 10 allows the construction target device to be selected depending on whether the construction target device is designated using a device name or a device number or a device symbol is selected using a drawing on the screen. It has become.

  In the isolation location designating unit 11, when constructing the construction target device registered in the construction target device registration unit 10, the isolation location and the implementation time (execution forecast) that should be isolated such as the closing operation of the valve and the power shut-off are performed. Is included).

  In the actual / plan input unit 12, the scheduled time and actual time for performing the isolation are input or changed.

  In the isolation part adjustment unit 13, when the isolation part needs to be changed, the isolation part can be changed. For example, when a construction target device is added or an isolation part is added, it may be necessary to expand the range of the isolation part. In such a case, the isolation location adjustment unit 13 adjusts the isolation location.

  The isolation part display part 14 is demonstrated using FIG. FIG. 3 is an explanatory diagram showing a specific example of the screen of the isolation location display unit 14 of FIG. As shown in FIG. 3, in the isolation location display unit 14, based on the information input in the construction target device registration unit 10, the isolation location designation unit 11, the actual / plan input unit 12 and the isolation location adjustment unit 13, Reference can be made according to time series.

  Next, the auxiliary means 4 will be described. The incidental means 4 has a collation unit 15 and a transfer unit 16.

  In the verification unit 15, the information related to the construction target device and the isolation location possessed by the isolation location adjustment unit 13 and the information related to the construction target device and the isolation location in the process possessed by the process attribute editing unit 6 are collated. Both pieces of information are linked. Specifically, a key code for connecting both databases is set.

  In the transfer unit 16, information related to the scheduled time or actual time for performing the isolation of the isolation part adjusting unit 13 based on the result of the verification in the verification unit 15 is transferred to the process attribute editing unit 6, and Information related to the scheduled time or actual time for performing the isolation analyzed and calculated by the time analysis unit 7 is transferred to the isolation part adjusting unit 13. However, in operation, when the scheduled time and actual time of isolation are input only to the process management means 2 side, information related to the scheduled time or actual time for performing the isolation is transferred from the time analysis unit 7 to the isolation point adjustment unit 13. Will only be done.

  The normal operation in the present embodiment configured as described above will be described with reference to FIGS. FIG. 4 is a process table showing a specific example of the isolation location in FIG. 1, FIG. 5 is a table showing data after input by the process editing unit 5 in FIG. 1, and FIG. FIG. 7 is a table showing data after being input by the process attribute editing unit 6 in FIG. 1.

  As shown in FIG. 4, each process is graphically input in the process editing unit 5. This “input graphically” means, for example, that the work is displayed by being drawn with a line (“work bar” or “process bar”) on the computer screen. Further, as shown in FIG. 5, the input data can display the work name, start date and time, and end date and time in the form of data.

  Linking indicating the context between the operations is performed by selecting the preceding “work bar” on the pointing device and then selecting the subsequent “work bar”. When this association is performed, as shown in FIG. 6, it is displayed as data of the preceding work barcode and the succeeding work barcode.

  When attributes such as remarks information and resource information are additionally input to the individual information (“work bar” or “process bar”) by the process attribute editing unit 6, the input data is shown in FIG. 7 is stored in a table format as shown in FIG. In addition, as resource information, information such as input artificial and used cranes is input, and when “level-1.0” is described in the resource information, the corresponding resource is uniformly set to 1 in the same period as each bar. It means to use 0 times. For this resource information, a name and a limit amount are registered in advance in the initial setting. As the remark information, a quarantine number or a symbol indicating quarantine work is input.

  Next, the time analysis performed in the time analysis unit 7 based on the data input as described above will be described with reference to FIG. FIG. 8 is an explanatory diagram showing the time analysis result of the time analysis unit 7 of FIG. 1, wherein (a) is a process table showing a specific example before the analysis, and (b) is a specific example after the analysis. It is a process chart.

  This time analysis is performed using the PERT method. As described above, the PERT method is a method of creating a schedule plan for each work, calculating the required time for the entire work, and clarifying the further to shorten the required time. In other words, the context between the tasks is linked in advance from the base work to the last work, and based on the work time from the start to the end of this work and the link indicating the context between the works. , All the work is ahead of time. From the process before the analysis in FIG. 8A, the process shown in the process after the analysis in FIG. 8B is performed. In contrast to this result, this time, paying attention to the resource, when the limit amount of the resource is exceeded due to duplication of work or the like, one of them is delayed in time, and the result is suppressed within the limit amount of the resource. However, since it is not possible to change a work for which a past record has been input, it is excluded from the object of being moved forward or backward.

  In addition, since the process will be changed if the time analysis or judgment of landscaping is performed before linking indicating the context between the above operations, a menu for executing the above time analysis and judgment of landscaping is prepared. However, unless this menu is selected, the time analysis and the judgment that the mountain breaks are possible cannot be performed.

  Next, the process is displayed on the process display unit 8 based on the data input as described above. Although the display of this process may be displayed in exactly the same way as in FIG. 2, remark information such as a device number and a company name can be attached to the process bar and displayed. Since it is not always necessary to display the same period as that of the input screen, it can be enlarged and reduced like a general OS function. The display period is moved using a scroll bar.

  The graph display unit 9 is arranged at the upper or lower part of the screen of the process display unit 8, and the display period and scale of the time axis are the same as those of the process display unit 8. The display format of the graph can be displayed for each resource (input artificial and used crane) or in total.

  The construction target device registration unit 10 will be described. Prepare in advance a drawing describing piping, valves, pumps, motors, instrumentation equipment, etc. on the piping instrumentation diagram. In the construction target device registration unit 10, the devices such as valves on the drawing prepared in advance are converted into buttons on the screen, and by selecting this device, the name or device number of the device subject to construction can be easily registered. (Application)

  The isolation part designation | designated part 11 is demonstrated using FIG. FIG. 9 is a table showing data after being input by the isolation location specifying unit 11 of FIG. In the isolation part designating unit 11, an isolation part is designated by selecting a buttoned device by the same mechanism as the construction target device registration unit 10, and this isolation period (in the isolation work and the isolation release work) The start and end dates and times) are also input together. In this case, the construction target device can be identified by a technique including color coding or highlighting. As shown in FIG. 9, the above data includes the isolation number, the construction target device name (device number), the isolation device name (device number), the isolation operation start date and time, the isolation operation end date and time, the isolation release operation start date and time, the isolation Displayed as the release work end date and time. When the construction target device is determined, the isolation location is almost determined, so the past results of the isolation location are accumulated and can be displayed as candidates.

  The isolation part adjustment part 13 is demonstrated using FIG. FIG. 10 is an explanatory diagram showing the integration of isolation in the isolation point adjustment unit 13 of FIG. 1, (a) is a configuration diagram showing a specific example before the integration, and (b) is a specific example after the integration. FIG. 11 is a table showing data after the change input of the isolation part adjusting unit 13 of FIG.

  This isolation point adjustment unit 13 is used by a person in charge of the electric power company, separately from the applicant for isolation, to reorganize the isolation plan by integrating a plurality of isolations.

  For example, in FIG. 10 (a), pump A and pump B carry out construction work at the same time, and valves A and B are fully closed as pump A is isolated, and valves C and D are fully closed as pump B is isolated. The pre-integration state for which operation has been applied is assumed. As shown in FIG. 10 (b), after the integration, the valves A and B can be isolated by performing the fully-closing operation of the valves E and F. In this case, the data is changed as shown in FIG. 11 and is instantly reflected in the isolated portion display unit 14 shown in FIG.

  In the isolation location display unit 14, the construction target devices and isolation locations registered so far are displayed at specific times. The conditions for extracting the construction target device to be displayed on the isolation part display unit 14 and the isolation part are as follows.

  When the time X is displayed on the isolation part display unit 14, the construction target device and the isolation part included in the following are displayed.

Start date / time of isolation work <Date / time X <End date / time of isolation release work Also, it is necessary to color-code the construction target device and the isolation location so that they can be distinguished.

  Furthermore, since the work target equipment and the isolation location during the isolation and isolation release operations require special attention, it is necessary to display the warning by highlighting or blinking.

  The extraction conditions in this case are as follows.

Quarantine work start date and time <Date and time X <Quarantine work end date and time
Or the date and time of start of the quarantine release operation <date and time X <date and time of ending the quarantine release operation In the collation unit 15, the quarantine information managed by the quarantine management unit 3 and the information related to the quarantine operation managed by the process management unit 2 are displayed. Comparison is performed in comparison.

  Specifically, the information corresponding to FIG. 11 from the isolation part adjusting unit 13 and the information corresponding to FIG. 7 from the process attribute editing unit 6 are extracted, and collation is performed according to the following algorithm.

  The construction target device name related to the isolation management means 3 shown in FIG. 11 and the device name column related to the process management means 2 shown in FIG. 7 are collated, and when the same device is displayed, extraction is performed for each device. Is called. However, the process management means 2 side targets only those items that are described as “isolation work”, “isolation release work” or “semi-isolation work” in the column of the isolation work.

  For each extracted device, the "isolation location device name" + "isolation (release) state" related to the isolation management means 3 shown in FIG. 11 is compared with the work name related to the process management means 2 shown in FIG. Then, the isolation number of the isolation management means 3 shown in FIG. 11 is copied to the isolation work column of the process management means 2 shown in FIG.

  In the case of the work for releasing the quarantine, a symbol (for example, “E”) indicating the quarantine release is added to the quarantine number so that the quarantine number can be distinguished.

  For those in which the collation is not completed despite the above processing, the collation is manually performed, and finally the isolation number of the isolation management means 3 shown in FIG. 11 is displayed in the column of the isolation work of the process management means 2 shown in FIG. To copy automatically.

  In the transfer unit 16, information is transferred using the isolation number in the isolation number column of the isolation management unit 3 and the isolation number column of the process management unit 2 as keys.

  According to this embodiment configured as described above, it is possible to link the database of the process management means 2 and the database of the isolation management means 3 within the scope related to the isolation. It is possible to refer to the isolation state of all at once.

  Thus, since the database of the process management means 2 and the isolation management means 3 are linked, it becomes easy to find omission of isolation application and omission of description of work process. As a result, it greatly contributes to work safety and safe operation of the plant. can do. Furthermore, since a plurality of quarantine states can be referred to at a time, it is possible to detect interference and inconsistency of the applied quarantine, and to confirm interference between the operation test and the quarantine.
