DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the embodiments of the present invention, first, an outline of a method of evaluating the damage mode of each component to be managed, particularly a "damage mode matrix table" will be described. I do.

In general, a large-scale system typified by a power generation plant is composed of a plurality of systems composed of a large number of facilities, and these facilities are composed of a single or a plurality of devices and devices, and individually. Are composed of many components. The present invention, from the viewpoint of maintenance and management of plant equipment, each component constituting the plant, equipment, devices, equipment, parts, parts ...
・ The journal is divided into a hierarchical structure that can be expanded from the upper level to the lower level and can be aggregated from the lower level to the higher level, and the damage status of each component belonging to the lowest level among the hierarchized levels is determined. The damage status of the entire plant is grasped by performing the evaluation retroactively to the components of the hierarchy.

That is, generally considered, a hierarchical structure in a plant can be represented by the following system (a). Equipment-equipment-equipment-parts (a) From the viewpoint of grasping the degree of damage, it is not sufficient to simply start with physically physically separable parts. Important parts of the above must be further divided into several lower-layer parts having different functions, and the aggregated damage status of these parts must be evaluated as the actual damage state of the part. This is called a part, and the hierarchical structure of the plant in consideration of such points can be expressed as the following (b). Equipment-equipment-equipment-parts-part (b) Even if the part is the same, if the part has a plurality of management targets, it is further expanded to more detailed parts to subdivide the information. In this case, the situation can be more accurately and easily grasped. In such a case, the situation can be represented by the following hierarchical structure (c). Equipment-equipment-equipment-parts-part-detailed part ... (c)

And

It should be noted that the relationship between each component and each form of damage is not fixed, and new damage may occur in a certain component, and unexpected damage may occur in an unexpected component. This may occur, and in some cases it may be necessary to expand to a lower hierarchy. In order to realize a management system that can cope with such situations during system operation, the number of components and the number of damaged forms must be changed at any time. Need to be kept.

In the example shown in FIG. 6, an arbitrary portion M2a on the damage form matrix table M2 and the damage form M2b are
Columns marked with the symbol *, for example, in FIG.
In the cell MA corresponding to M2a1 and the damage form “crack” M2b1, the evaluation judgment result is displayed on the damage degree of the specific damage form that can occur (here, the degree of crack propagation to the body trunk). I have. That is, the cell MA
Is evaluated for each cell marked with * in the damage form matrix table M2 represented by the formula (1).

FIG. 7 shows the damage form matrix table M of FIG.
2 is a configuration diagram of a damage degree evaluation method definition table 11 that defines and stores an evaluation method for performing an evaluation determination for each cell displayed in FIG.

The damage degree evaluation method definition table 11 is shown in FIG.
The following (d) to (n) are the same as the number n of the damage forms that can occur in the part a of the part A corresponding to the row direction of the cell.
(F) are defined, and n cell damage degree evaluation method definition sheets 11 (1), 11 (2),..., 11
(N). Judgment items (p ₁₁ , p ₁₂ ,..., P _1m ) (d) Judgment values (q ₁₁ , q ₁₂ ,..., Q _1m ) (e) Judgment method (j ₁₁ , j ₁₂ ,..., J _1m ) (f) Here, the judgment item p ₁₁ is based on the judgment method defined for j ₁₁ , and q ₁₁ is used as a judgment value. Be evaluated.

The cell damage degree evaluation method definition sheet 11
The function f (p) outside the cell of (1)₁₁, P ₁₂, ... ,, p

The case where there are m judgment items for
The evaluation result of ru1 is determined by the judgment item (p₁₁, P₁₂, ... ・
・, P_1m) Is given as a function. Here, the judgment item
(P₁₁, P₁₂, ... ,, p_1m) Is not necessarily multiple
Need not be, for example, p₁₁Can be evaluated with only one
It is possible.

As described above, since the evaluation method can be defined independently for each cell, it is possible to flexibly cope with a later change or addition of the evaluation method.

FIG. 8 is a specific configuration diagram of the cell damage degree evaluation method definition table shown in FIG. 7, which is developed by taking the "body trunk" of the portion M2a in FIG. 6 as an example. That is, as shown in FIG. 6, four damage modes (cracks, run-outs,
Contact marks, magnetization) are defined, and a damage degree evaluation method definition sheet 11 (n) shown in FIG. 7 is created for each damage form.

Therefore, as shown in FIG. 8, the cell damage degree evaluation method definition table “body trunk” has a total of four cell damage degree evaluation method definition sheets 4 (1), 4 (2), and 4 (3). , 4
This is constituted by (4).

As described above, the damage degree evaluation method definition sheet 11 (n) defined for each cell is compiled as a damage degree evaluation method definition table 11 for each part and managed by the cell damage degree evaluation method definition unit 1. You.

For example, when the cell MA of the damage form matrix table M2 shown in FIG. 6 displayed on the display device 37 is activated (selecting the intersection M2a1 and the damage form M2b1 with the mouse), the position of the cell MA is changed. Is read, and the corresponding degree of damage evaluation method definition sheet 11 of the degree of damage evaluation method definition table 11 as shown in FIG. 7 for the corresponding cell MA of the cell damage degree evaluation method definition unit 1 is read. (N) is selected.

Subsequently, the cell damage degree evaluation method definition unit 1 determines the judgment items defined in the damage degree evaluation method definition sheet 11 (n) selected by adding the cell position identification information and the damage items corresponding thereto. A request is made to the data input unit 10 for actual measurement data for determining the actual state. Data input unit 10
Is an arbitrary database 3 in which actual measurement data is stored in advance.
4 and the data corresponding to the judgment item is taken. Alternatively, the data acquisition sensor 35 corresponding to the determination item
Import data directly from. Then, cell position identification information and determination items corresponding to the captured actual measurement data are added,
It is output to the cell damage degree determination unit 2.

Next, in the cell damage degree evaluation section 2, the cell damage degree evaluation method definition sheet 11 of the damage degree evaluation method definition table 11 defined by the cell damage degree evaluation method definition section 1 is provided.
The degree of damage is determined from the actual measurement data taken in from the data input unit 10 using the evaluation method based on the determination method and the determination value of each determination item in (n). As the determination result, for example,
In accordance with the degree of the result of comparison with the judgment value, the levels are classified into "normal", "caution", and "abnormal", and the judgment result is sent to the cell judgment result output unit 3 as the actual damage. The method of dividing the level of the judgment result is defined in the judgment method of the cell damage degree evaluation method definition table 11 (n).

Next, the cell judgment result output section 3 outputs the judgment result based on the judgment result sent from the cell damage degree judgment section 2 and the corresponding cell position identification information to the damage degree judgment result output section 36. The information is displayed on the damage form matrix table displayed on the display device 37 via the display unit 37.

For example, when the state of occurrence of each damage mode is displayed in each cell of the steam turbine / axle damage mode matrix table M2 in FIG. 6, a damage actual state matrix table M3 is obtained as shown in FIG. The damage actual state matrix table M3 has a site M3a on the vertical axis and a damage mode M3b on the horizontal axis, and indicates “normal”, “caution”, and “normal” in appropriate cells at each intersection.

Next, the result of the judgment of each cell by the cell damage degree judging section 2 is sent to the part damage degree judging section 5, and in accordance with the comprehensive evaluation method defined by the part damage degree evaluation method defining section 4, the unit is evaluated in units of parts Is comprehensively evaluated. The result is output to the part determination result output unit 6. The comprehensive evaluation method defined in the site damage degree evaluation method definition unit 4 is generally expressed by the following (g) as a function of the determination results of all cells belonging to the same site.

Fp (α _a1 , α _a2 ,..., Α _an ) (g)

Here, α _a1 , α _a2 ,..., Α
_an is n damage forms 1, 2,...
n is the determination result. In the simplest case, the judgment result of each cell is described as “normal”, “caution”, “abnormal”
If it is determined at a simple stage, a method of selecting the most severe one of α _a1 , α _a2 ,..., Α _an as the function fp can be considered. It should be noted that the evaluation expression represented by the above (g) before being converted into the simple stages of “normal”, “caution”, and “abnormal” is passed to the site damage degree evaluation method definition unit 4 as it is, It can also be evaluated by the above function.

Next, the part determination result output section 6 adds the part determination result output position information to display the evaluation result as the part determined in this manner on the damage actual state matrix table M3 shown in FIG. , Damage degree determination result output unit 3
6 and displayed on the display device 37 as a damage actual state matrix table M4 shown in FIG. The damage actual state matrix table M4 is obtained by providing a part evaluation result cell M4c in the up-down direction in the cell in the rightmost column of the damage actual state matrix table M3 in FIG. 9, and displays the result of the comprehensive evaluation judgment in the same part.

Next, the result of the comprehensive evaluation judgment obtained by the part damage degree judging section 5 is sent to the component damage degree judging section 8,
In accordance with the high-level evaluation determination method defined by the component damage degree evaluation method definition unit 7, a high-level evaluation determination is performed for each component, and the result is determined as a high-level evaluation determination result by the component determination result output unit 9.
Output to

The determination method defined in the component damage degree evaluation method definition unit 7 is generally a determination result of all parts (assumed to be parts a to q) belonging to the same part; βa, βb,.
.., Βq, which is a function of βq.

Fe (βa, βb,..., Βq) (h)

Here, the simplest function form is a method of selecting the strictest one among the judgment results βa, βb,..., Βq of each part.

In the part judgment result output unit 9, as shown in FIG. 10, in the damage actual state matrix table M3, as shown in FIG. The output device 3 adds the output position information to the display device 3 via the damage degree determination result output unit 36.
7 is displayed. For example, it is displayed in the cell M4e of the component evaluation result provided at the bottom of the cell M4c in the rightmost column of the damage actual state matrix table M4d in FIG.

As described above, the cell processing unit 31, the site processing unit 3
2. Since the parts processing unit 33 is defined in the unit of the damage form matrix table shown in FIG. 6, it can be extended according to the range of the equipment to be managed—parts—parts and the damage form as the equipment management system. It can be said that the scalability of the system support range is very high.

As can be seen from the system A3 of the steam turbine facility equipment in FIG. 11 and the system A4 of the labyrinth part equipment in FIG. 12, the levels of the parts in the damage actual state matrix table M4 shown in FIG. Not necessarily.

That is, in the system A3 of FIG. 11, the labyrinth portion is represented as a part. However, when the details are to be confirmed, it is understood that the labyrinth portion is developed as a system A4 in FIG. May be easier. Therefore, when such a concept is applied to the damage actual state matrix table M4 in FIG. 10, for example, a damage actual state matrix table M5 as shown in FIG. 13 is obtained.

In FIG. 13, each cell of the labyrinth portion as a portion is shaded because the entire labyrinth portion is evaluated by a matrix having a different configuration from the other portions of the lower hierarchy. Means that.
“Normal” in the part evaluation result cell M5a indicates the result of the comprehensive evaluation judgment in the matrix table. This is because the damage actual state matrix table M4 in FIG.
In the case where there is a damage type that is hierarchically different from other parts in the same row, as in the modified display example, it indicates that another matrix may be arbitrarily defined.

As described above, according to the present embodiment, it is possible to provide an equipment management system that can flexibly cope with various changes in equipment management methods that are expected to occur in the future in the following points. .

First, by introducing the damage form matrix table, the actual damage state can be grasped at a glance, and it is possible to easily cope with the damage form to be managed and the increase or decrease of the occurrence site.

Second, by making it possible to construct a damage degree evaluation method on each cell of the matrix table,
Changes in evaluation criteria, evaluation methods, etc. can be easily handled by only partially modifying the database.

Third, using the structure of the matrix table, for example, the cell damage evaluation method is applied to each cell, the site damage evaluation method is applied to each row (site), and the component damage evaluation method is applied to the rightmost cell column ( By allocating to parts, it is possible to partially change the evaluation method as a part (upper level of equipment system) without affecting other parts, and an economical system that matches the actual situation of equipment operation It can be.

In the above-described embodiment, the table data storage means has been described as being provided in the cell damage degree evaluation method definition unit 1. However, the present invention is not limited to this. For example, it can be provided at an appropriate place. Further, it is obvious that the system configuration can be freely changed as appropriate, for example, the definition units 1, 4, 7, etc. are also provided in the database 34.

Next, a modification of the first embodiment of the present invention will be described with reference to FIGS. 10, 14 and 15B.

In this example, a component-level equipment status summary table M6 shown in FIG. 14 is created based on the site-level damage status matrix table M4 shown in FIG. 10, and the respective equipment status summary tables M6 are consolidated. Then, an equipment-level equipment summary table M7 shown in FIG.
The equipment-level equipment status summary table M8 shown in FIG. 15B is created by integrating the equipment-level equipment status summary table M7 shown in FIG.

First, in the damage actual state matrix table M4 shown in FIG. 10, a part name corresponding to the part M4a constituting the target component in the damage actual state matrix table M4,
FIG. 1 summarizes the site evaluation result M4c of the rightmost cell, which is the evaluation result of the damage status of each site, in association with each other.
4 can be created. FIG. 14 shows the damage state M6a at the part (axle) level.
And a list of damages (evaluation results) M6b at the level of each part constituting the part (axle). These table creation processes may be performed by the damage degree determination result output unit 36, or such a processing unit may be provided in the display device 37, and may be provided at an appropriate place in the equipment management system 100. Can be.

Next, when an equipment summary list M6 as shown in FIG. 14 is determined for all the related parts and parts, these information are stored in the upper level equipment according to the equipment system to which the parts and parts belong. It can be summarized in the equipment status information.

That is, to simplify the explanation, It is assumed that each of the turbine systems A3 has a hierarchical structure as shown in FIG.

The equipment summary table M6 at the part (axle) level in FIG. 14 includes the “cabin”, “moving blade”, “static vane”, and “nozzle box” in the part level hierarchy of the system A3 in FIG. Each is created correspondingly. Then, the component names and the component evaluation results of the equipment status summary table at each component level of “axle”, “cabin”, “rotor blade”, “stationary blade”, and “nozzle box” are taken in and summarized as shown in FIG. An equipment summary list M7 at the equipment (turbine body) level of the upper hierarchy shown in FIG. In the equipment summary table M7 of FIG. 15A, the equipment name “turbine body” and the equipment evaluation result “abnormal” are displayed in the lower cell M7a, and the “turbine body” is displayed in the upper cell M7b.
Are displayed and the component evaluation results are displayed.

Similarly, for the “main valve”, “control safety device”, “condenser”, and “feed water heater” belonging to the same hierarchy as the “turbine body” shown in FIG. The device names and the device evaluation results of each of the prepared summary tables are read and compiled. As a result, an equipment summary table at the equipment (turbine equipment) level shown in FIG. 15B is created. This FIG.
In the equipment level equipment summary table M8 shown in (B), the names of the equipment constituting the "turbine equipment" and the equipment evaluation results are displayed in the upper cell M8b, and the names and equipment of the "turbine equipment" are displayed in the lower cell M8a. The evaluation result is displayed.

As described above, when the damage actual matrix table M4 shown in FIG. 10 for each part / part is obtained by the processing according to the present embodiment, based on the information, the hierarchy of the equipment system used in the system is determined. 14 and 15
As shown in (B), it is possible to sequentially summarize (higher-level aggregation) the equipment status summary table at the upper level, and to express the damage status of the equipment collectively and simply.

With this configuration, on the contrary, it is easy to know the detailed information of the problem location from the equipment level summary table M8 of the equipment level in FIG. For example, as shown in FIG. 15B, when the equipment evaluation result of the turbine equipment is displayed as “abnormal”, if the user selects a turbine main body that belongs to a component that is “abnormal”, the breakdown shown in FIG. It is possible to call up the equipment-level equipment summary table M7 at (A) and narrow down the problem location (lower-order development). Further, FIG.
In (A), when an axle displayed as "abnormal" is selected, the equipment fact summary table M6 in FIG. 14 can be called up, and it is possible to further narrow down problem areas. Since the procedure of the higher-level aggregation and the lower-level development can be freely performed according to the equipment system used by the system, it is possible to refer to the actual equipment status at a desired level.

Next, a description will be given of a case where the inverse conversion is performed from the component level equipment summary table M6 of FIG. 14 to the damage actual matrix table M4 of FIG.

As described above, the conversion from the damage actual state matrix table M4 in FIG. 10 to the equipment actual state summary table M6 in FIG. 14 can be performed simply by omitting the cells in the damaged form part of the matrix table. If this relationship is stored, it can be called and displayed from the equipment actual state summary table M6 to the damage actual state matrix table M4. Thus, it is possible to reconfirm the problem location and the details of the problem while using the general information as a reference.

Next, another modified example of the first embodiment of the present invention will be described with reference to FIGS.

This modification is an example in which a plant has a plurality of plant systems, that is, a hierarchical structure. Starting from a “damage form matrix table” in each hierarchical structure,
The processing of creating the "damage actual state matrix table" and further the "equipment actual state summary table" is all performed by the equipment management system configuration shown in FIG. In this modified example, by displaying in parallel the equipment status summary tables for components having substantially the same specifications in the equipment status summary tables created in each hierarchical structure, another hierarchical structure (plant system), that is, another The present invention facilitates side-by-side comparison of damage status of components having substantially the same specifications belonging to equipment and makes it possible to grasp the deterioration characteristics of components of the same type.

For example, a plant system table A5 shown in FIG.
It is assumed that a hierarchical structure including devices, components, parts, and the like is formed corresponding to the facilities 1 to 3. Also, it is assumed that the axles A5a, A5b, and A5c, which are component components, have almost the same specifications.

Thus, in the equipment management system shown in FIG. 5, for each equipment, the "damage form matrix table" shown in FIG. 6 is created from the "damage form matrix table" shown in FIG. Further, a summary table of the actual equipment state at the component level of each individual equipment shown in FIG. 14 is created. Next, the summary table of the equipment status for each of these equipments is put together in a display format of the format shown in FIG.

Usually, it is not rare that a single power plant or the same electric power company has a plurality of the same type of equipment. Efforts to ascertain the degradation progress characteristics of the steel are rather routine. In such equipment of the same type, the hierarchical structure is inevitably the same. Therefore, the equipment summary table M6 shown in FIG. 14 for each equipment at an arbitrary hierarchy (level) is required. By creating and displaying the equipment fact summary table M9 in FIG. 17 (an example in which the axle equipment fact summary tables M9a, M9b, and M9c are displayed in parallel), damage to a plurality of identical devices belonging to each facility is displayed. Not only can the degree of progress be compared, but the analysis of the detailed information also makes it easier to consider whether there is a general rule for the characteristic.

As is clear from FIG. 17, the equipment does not necessarily have to be of the same type, and it is sufficient that the configuration in the leftmost column of the equipment status summary table M9 is the same, so that the specifications can be displayed in the same format. Elements may be used, and a plurality of components having the same specification in the same facility (for example, a plurality of water supply pumps that can be deployed in the same component in a lower hierarchy) can be similarly implemented.

Next, still another modification of the first embodiment of the present invention will be described with reference to FIGS.

In this example, not only the abnormal evaluation level, but also “Waiting for inspection”, “Inspection”,
The work state value of "evaluating etc." is displayed.

First, at the time of the data fetching process by the data input unit 10 in FIG. 5, it is determined as follows according to the data collection status. "Waiting for inspection": State where the relevant data has not been collected (input form is output but not input) "Checking": State where the relevant data has been partially collected but not completed. "Evaluating": The collection of the relevant data has been completed, but the validity of the data has not been determined

The priority order of these status value displays is as follows.
For example, if priority is given to the item that is the most delayed in time series, the items are displayed in the order of “waiting for inspection”> “under inspection”> “under evaluation”. If the display of these status values is prioritized over the anomaly evaluation level and displayed in a higher level, for example, at the equipment level of the equipment system, the status of inspection and evaluation of each equipment can be listed, and work delays can be included. It is possible to grasp the actual condition of the equipment. FIG. 18 shows an example of this, and shows an example in which the equipment summary list applied to FIG. 15B is modified.

The work state value display M10a, M10b, M10c of the equipment summary table M10 in the figure can be applied to the damage situation matrix table M4 of FIG. 10, and an example is shown in FIG. The damage actual state matrix table M1 shown in FIG.
The indication "waiting for inspection" of the cell MA of No. 1 indicates that the inspection for the damage form (run-out) of the part (coupling) has not been performed. Since this non-installed state value was prioritized over the abnormal level, the part evaluation result M11a as a coupling and the part evaluation result M as an axle
11c is also displayed as "Waiting for inspection". in this way,
By introducing work status values into the damage status matrix table,
Here, it is possible to configure a screen for urging the user to perform an inspection item called “measurement of coupling shake”.

FIG. 20 is a configuration diagram of an equipment management system according to the second embodiment of the present invention.

In FIG. 20, the same reference numerals as in FIG. 5 showing the first embodiment denote the same or corresponding parts, and a description of the overlapping parts will be omitted.

In FIG. 20, the equipment management system 100
In the cell processing unit 31A of A, a cell treatment method determination unit 13 is added to the cell processing unit 31 of the first embodiment. In the part processing unit 32A, a part treatment determination unit 16 is additionally provided in the part processing unit 32 of the first embodiment. Also, in the component processing unit 33A, the component processing unit 33 of the first embodiment is used.
A part treatment method determining unit 19 is additionally provided. Further, the equipment management system 100A additionally includes a treatment method output unit 39.

Here, the cell treatment method determining unit 13 fetches the result of the evaluation judgment from the cell judgment result output unit 3, defines the treatment method in advance, and refers to a treatment method decision table to be described later after defining and storing the treatment method. A treatment method to be evaluated is determined and treatment method information is output.

The site treatment method determination section 16 fetches the result of the comprehensive evaluation determination from the site determination result output section 6 and refers to a later-described treatment method determination table that defines and stores a treatment method, and determines a corresponding comprehensive evaluation determination target. Is determined and the treatment method information is output.

The component treatment method determination unit 19 fetches the result of the higher evaluation judgment from the component judgment result output unit 9 and refers to a treatment method determination table that defines and stores the treatment method in advance, and refers to the corresponding higher evaluation judgment target. Is determined and the treatment method information is output.

FIG. 21 shows a damage actual matrix table M12 used in the second embodiment. This damage actual matrix table M12 is the damage actual matrix table M4 of FIG.
Is added to the column of the site treatment method M12a.

FIG. 22 shows a treatment method determination table 12 used for determining a treatment method. The treatment method determination table 12 is registered in each part of the damage actual state matrix table M12 in each part. The number of damaged forms to be managed (12 (1), 12 (1) in FIG. 22)
(2),..., 12 (n)) are prepared.

The function of the treatment method determination table 12 will be described with reference to the treatment method determination table 12 (1) shown in FIG.

The treatment method determination table 12 (1) indicates that the damage type 1 is a damage level 1 in which the damage type 1 is a preset classification.
2c, a treatment method 12d determined corresponding thereto, a storage cell 12a of the damage degree determination value f real as the actual state of the damage form transmitted from the cell determination result output unit 3, and a damage degree determination value f real. The damage level 12c (fa ₁₁ , fa ₁₂ ,
.., Fa ₁₅ ) ”, and a damage level adjustment logic 12b for adjusting the relationship.

The combination of the damage level 12c and the treatment method 12d is, for example, the lightest damage level fa as the treatment method.
Treatment methods Sa ₁₁ corresponding to the _11, usually, Sa _11: with a minimum of care, as it is to use. Conversely, treatment methods Sa ₁₅ corresponding to the most stringent level of injury fa ₁₅ may, Sa _15:
It is determined that a new part A should be replaced.

There are cases where the preset damage level classification (fa ₁₁ , fa ₁₂ ,..., Fa ₁₅ ) and the treatment method 12 d do not correspond properly depending on the system. In this case, damage level adjustment is performed. The logic 12b is adjusted.

In the example of FIG. 22, the equipment management system 100
The damage degree evaluation category used by A is, for example, “normal”,
"CAUTION", when the "abnormal", the damage level adjustment logic 12b methods of treatment determination table 12 (1), the "attention" to an OR condition between fa ₁₁ and fa _12, the "abnormal" f
It is implicated as an OR condition between a ₁₃ and fa ₁₄ and fa _15.

Note that, for example, “caution” is changed to fa ₁₁ or f ₁₁
a was the OR conditions, such as _12, may be used as the selection item by the system user to directly displayed in parallel treatment methods applicable, damage degree judgment value f re as actual damage form
This is to enable automatic selection of a treatment method according to al.

The cell treatment method determination unit 13 transmits to the treatment method output unit 39 a treatment method candidate corresponding to the degree of damage of each damage form belonging to the site determined using the treatment method determination table 12.

The treatment method output section 39 is, for example, a site treatment method display M on the damage actual state matrix table M12 in FIG.
A display cell for each part 12a; M12b to M12g...
Is clicked, another window is called up and the treatment method of the corresponding site is displayed. For example,
The contents of B1a of the example of the part processing display B1 in FIG. 23 are displayed corresponding to the cell M12b that also displays the treatment method for each part in FIG. Further, the contents of B1b in FIG. 23 are displayed corresponding to the treatment method display cell M12c for each part in FIG.

The site treatment method determination section 16 collects the cell treatment methods as they are and summarizes the treatment methods for the entire site as a list. The site treatment method display M12a in FIG.
When is clicked, for example, the site treatment method list and the site treatment method output position information in FIG. 23 are output to the treatment method output unit 39 and displayed in another window.

FIG. 23 shows, in parallel, treatment methods according to the degree of damage for all the damage forms evaluated in FIG. 21 other than “normal”. Each row in FIG. 23 is a treatment method corresponding to each cell, and when this is viewed in units of parts, it is a part treatment method. For example, the part "body trunk"
For, since two locations of the damage modes “runout” and “scratch” are to be evaluated, in FIG. 23, the cell B1a indicating the treatment method is displayed in parallel with each damage mode. The site treatment methods M12d and M12e shown in FIG.
Is not displayed in FIG. 23 because the evaluation result is “normal”.

Further, the system user can review the contents displayed in this window as appropriate (removal of unsuitable treatment methods or combine them), regroup them into new treatment methods, and register them as site treatment methods. The site treatment method determination unit 16 gives priority to the contents of correction by the system user. For example, the treatments for the two types of damage (runout and scratches) on the “body trunk” in FIG. 23 can be summarized as in the example of the component treatment method display example B2 shown in FIG.

Next, the part treatment method determining unit 19 receives the treatment methods for each part determined by the part treatment method determining unit 16, collects them as they are, and compiles them as a treatment method list for the entire part. Furthermore, when the part treatment method display M12h in FIG. 21 is clicked, for example, the part treatment method display example B2 in FIG. 24 and the output position information of the part treatment method are output to the treatment method output unit 39 and displayed in another window. I do.

Here, FIG. 24 is a display example corresponding to the cell M12h of the part treatment method display of FIG. 21, and is a conversion example of the part level treatment method to the part treatment method of FIG. This is an example in which the system user collectively displays items related to each other in the matrix table of the site treatment method list in FIG. 23. The treatment method B1a and the treatment method B1c in FIG. B2a is created, and similarly, the treatment method B1b and the treatment method B1d of FIG. 23 are combined to create the treatment method B2b of FIG.

Therefore, when the system automatically outputs the part treatment method, the cell treatment method list of the part is output as shown in FIG. 23. By giving the editing function by the system user also to the method determining unit 19, it is possible to output the integrated treatment method as shown in FIG.

Next, a modification of the second embodiment of the present invention will be described with reference to FIGS.

This example corresponds to the site treatment method determining unit 1 shown in FIG.
The treatment method for each component defined in 6 is consolidated as a treatment method as a device according to the relationship between the device and the component that is a component thereof, and the same applies between the layers of the facility system of the device and the device, and the device and the device. Next, treatment methods at the next lower hierarchical level are collectively summarized, and FIGS.
As in the description of (B), the summary table of the facilities was developed,
Sub-development is also possible.

First, the actual damage matrix table M shown in FIG.
12 is converted into a component-level equipment status summary table M13 shown in FIG. 25 by the same processing as the conversion of the original damage status matrix table M4 of FIG. 10 into the equipment status summary table M6 of FIG.

FIG. 25 is a diagram showing the actual equipment summary M13 shown in FIG.
In the equipment summary table M6, the site evaluation result display cell M6b
A part treatment method display cell M13c is added to a part evaluation result display cell M13b corresponding to
This is obtained by adding a component treatment method display cell M13e to a component evaluation result display cell M13d corresponding to 6a. When an arbitrary site corresponding portion of the site evaluation result display cell M13b is selected, another window is called up, and in this window, a treatment method of the corresponding site is selected and displayed from the treatment methods of FIG. Similarly, the component treatment method display cell M1
When 3e is selected, the component treatment method shown in FIG. 24 is displayed.

The equipment summary list M13 shown in FIG. 25 is shown in FIG.
As described above, the part treatment method display cell M13c and the part treatment method display cell M13e are added to the equipment actual state summary table M6, so that the equipment actual state summary table M13 can also be aggregated at a higher level. Therefore, FIG. 15 (A) and FIG.
Corresponding to (B), it is possible to obtain the equipment level summary table M14 of FIG. 26 and the equipment level summary table M15 of FIG.

On the other hand, it is also possible to develop the equipment actual summary table M15 from the equipment actual summary table M15 of FIG. 27 to the equipment actual summary table M14 of FIG. 26 and the equipment actual summary table M13 of FIG.
13 can also be converted back to the damage status matrix table M12 in FIG.

For such high-level aggregation of the treatment method, the conversion method from FIG. 23 to FIG. 24 used at the time of high-level aggregation from parts to parts can be applied as it is. Unless corrections are made in the human system in the course of this conversion, the treatment method list becomes larger as it goes up in the equipment system. However, the equipment status summary tables M13 to M15 have only a function of calling these lists. Therefore, there is no hindrance to these higher-level aggregation operations.

It should be noted that such a treatment method is determined from the lower level of the equipment system, and is determined stepwise for each level while performing upper aggregation toward the upper level of the equipment system. In such a case, it can be displayed step by step for each level.

By arbitrarily performing such higher-level aggregate display or lower-level expanded display, a treatment method corresponding to equipment or equipment at that level can be called from the equipment status summary table at any level of the equipment system. Since the matrix expansion display is possible, information at the level required by the system user can be efficiently obtained.

Next, a third embodiment of the present invention will be described with reference to FIGS.

In the third embodiment, in the damage form matrix table of the first embodiment, the intersection (cell in the matrix table) of the part to be managed and the damage form corresponding to the part is set in the damage form matrix table of the first embodiment. A "management form matrix table" containing management form names indicating management methods is displayed, and this management state is displayed by color coding or the like.

The equipment management system according to the present invention starts from the damage form matrix table M2 shown in FIG. 6 as a result of the observation of the mechanical parts, and starts the damage actual state shown in FIG. 10 to clarify the actual damage state of the mechanical parts. Matrix table M
4, or is based on deriving the damage actual state matrix table M12 of FIG. 21. When this is developed for a thermal power plant, special conditions as described below in the relevant field are added. This makes it easier to use.

Now, regarding the various types of damage that can occur to various devices, parts, and parts depending on the equipment constituting the thermal power plant, a series of procedures from the discovery method to the follow-up investigation and the implementation of countermeasures. Analyzing the management method of, it has been found that several patterns hold. FIG. 28 is a management state definition table C1 in which the patterns are classified and defined as management modes. Almost all damage types found in thermal power plants fall under this category.

The management form definition table C1 shown in FIG.
Is applied to each damage form in the damage actual state matrix table M4 in FIG. 10, the asterisk can be replaced with the management form name according to the actual management method of each damage form, and the site treatment method display By adding the cell and the component treatment method display cell, a new management form matrix table M16 as shown in FIG. 29 having the same format as the damage actual matrix table M12 shown in FIG. 21 is obtained.

The management form matrix table M16 is also a matrix table showing a management method of the damage form that can occur in each part, and the management form to be applied for the inspection of the damage form can be known. It becomes possible to know the outline of the work to be performed.

The management form matrix table M16
It should also be noted that not all the management modes indicated in the above are necessarily carried out at every regular inspection. For example, the “remaining life” defined in FIG. 28 is generally performed at a long cycle of about 10 years, and when an arbitrary periodic inspection is considered, the management form is skipped. It can happen. In such a case, it is desirable that the cell in the management mode be invalidated (even if selected). This means that the management form matrix table M16 can be used for management of inspection work to be performed in the periodic inspection, and various uses are conceivable.

In order to make the management form matrix table M16 have the function of the damage actual state matrix table M12 of FIG. 21, the damage actual state in the damage actual state matrix table M12 is represented by the character expression of “normal”, “caution”, and “abnormal”. For example, instead of the evaluation level in the above, for example, the display of the management form name is left as it is, and each is displayed in a color such as green, yellow, and red. In this way, if the management form matrix table with the damage level color display is newly implemented in the same way as the damage actual state matrix table, conversion to the equipment actual state summary table, etc. will be performed in By using the display, it can be generated as it is, and can be implemented in a manner similar to the first and second embodiments.
