により決定する。この式における右辺第２項を重心ｃｓに加えることにより、ランダムに重心座標（ｃｊ）がずれ、これが状態図形の描画位置のずれを引き起こす。続いてステップＳ４で、次式により状態図形のコントロールポイントを決定する。
【００９９】
【数２】

【０１００】
この場合にも右辺第３項によるランダムな成分の加算でコントロールポイントに揺らぎを与え、結果として状態図形に揺らぎが与えられる。
【０１０１】
このようにして状態図形のコントロールポイントが決定されてならば、ステップＳ５で、各コントロールポイントを通過するベジェ曲線を描画し、図５の状態表示図面６２のように表示してユーザに示す。
【０１０２】
この図２５のステップＳ３〜Ｓ５の処理は、図２６のステップＳ３〜Ｓ５にまとめて示す処理となる。
【０１０３】
図２７は、図２５，図２６に示した手書き風図形作成処理で使用される基本状態図形の登録データである。この基本状態図形は、開を示す「○」、中間開を示す「△」、閉を示す「×」のそれぞれにおいて、基本状態図形３０−１，３０−２，３０−３を準備している。コントロールポイント座標は、基本状態図形３０−１については６ポイント、基本状態図形３０−２についても６ポイント、基本状態図形３０−３については５ポイントを決めている。
【０１０４】
更に、これは基本状態図形を作成するベジェ曲線の数として、基本状態図形３２−１については１本、基本状態図形３２−２については３本、基本状態図形３２−３については２本を、それぞれコントロールポイントに対応して定義している。
【０１０５】
したがって、図２７のような基本状態図形のデータから基本コントロールポイントの座標を取得し、図２５のステップＳ４のようにシンボル図形の重心座標とサイズを用いてコントロールポイントに揺らぎを与えることで、描画ごとに揺らぎを持った状態表示図形を生成することができる。
【０１０６】
このような本発明における機器シンボルに重ねて表示する状態表示図形に揺らぎを与える方法としては、これ以外に次のような方法をとることもできる。
（１）ユーザ別基本状態図形の登録
通常、人が描いた図形は描く人によって異なり、同じ人が描けばよく似た図形になるという特徴も考えられる。この特徴を表現するために、ユーザごとに異なった基本状態図形、即ち実際に手描きした図形もしくは基本コントロールポイントを登録する。そして図面を開く際に保守管理データベースサーバ１４からアイソレーション票を読み出す際に、作成者を抽出し、作成者に対応した基本状態図形を選択して使用することで、作成者の癖に応じた状態表示図形を機器シンボルに重ねて表示することができる。
（２）重要度別基本状態図形の登録
機器番号ごとに重要度のパラメータを持たせ、重要度に応じ基本状態図形を登録することによって、重要な機器については通常より目立つ状態表示図形を描画する。
（３）重要度によるサイズ（ｓｉｚｅ）への重み付け
機器番号ごとに重要度のパラメータを持たせ、重要度に応じてｓｉｚｅパラメータを調整することによって、重要な機器の状態表示図形は少し大きめに強調描画する。

BACKGROUND OF THE INVENTION
The present invention relates to a maintenance management system, method, and program for creating an isolation plan used for an operation of isolating a specific device at the time of repair and inspection of a plant, and in particular, confirming a device operation state in an isolation plan drawing. The present invention relates to a maintenance management system, a method, and a program that are displayed so as to be easily performed.
[0002]
[Prior art]
Conventionally, when a failure occurs in a plant such as a nuclear facility, an isolation operation that isolates the failed device by first closing a valve around the failed device is performed, and then the failed device is replaced after the isolation operation. Perform the work.
[0003]
Also, depending on the plant, there may be legally required periodic inspections. During this periodic inspection, an isolation operation is performed to isolate the inspection target equipment, and the work such as replacement of the equipment is performed after the isolation operation. To implement.
[0004]
In such an isolation operation, conventionally, a maintenance staff accesses a server that manages maintenance management drawings, searches for a CAD drawing of a failure location, prints it out, and around the failed device on the CAD drawing. Prepare the isolation plan drawing by manually writing the state figure indicating the open / closed state of the valve necessary for the isolation operation on the symbol representing the device such as the valve, and check the isolation status at a glance By making it possible, we are working to improve operational safety.
[0005]
[Problems to be solved by the invention]
However, in the conventional process of creating an isolation plan drawing, it is necessary to manually determine the isolation range for the target device, open / close state of the valves included in the isolation range, etc. by looking at the CAD drawing printed out by maintenance personnel. There is a problem that it takes time and labor to create a plan drawing.
[0006]
In addition, when a failed device is replaced, the replacement device is used as an index, and a list of devices that have performed isolation operations is created and saved as a maintenance record.If the same device fails later, Search the saved target list, write the isolation plan drawing again by manually writing the open / closed state of the valve for isolation on the CAD drawing printed by maintenance personnel while viewing this list. However, it still takes time and effort, and the past maintenance history cannot be fully utilized.
[0007]
It is an object of the present invention to provide a maintenance management system, method, and program that can efficiently create a plan drawing for an isolation operation when equipment is replaced.
[0008]
Another object of the present invention is to provide a maintenance management system, method, and program that make it possible to confirm an isolation status at a glance by highlighting a status display graphic indicating an operation status on a device symbol. .
[0009]
[Means for Solving the Problems]
FIG. 1 is a diagram illustrating the principle of the present invention. The present invention provides a maintenance management method for creating an isolation plan used for an operation of isolating a specific device at the time of repair and inspection of a plant.
[0010]
This maintenance management method
A drawing search step for searching and displaying a drawing including a device to be quarantined;
An operation state setting step for determining an isolation range on the drawing and setting an operation state for isolation for each operation target device existing in the isolation range;
A plan drawing creation step for creating an isolation plan drawing in which a hand-drawn state display figure is displayed on a device symbol in correspondence with the operation state of the operation target device;
A saving step for saving the plan information including the isolation plan drawing by a confirmation operation;
It is provided with.
[0011]
For this reason, by identifying the isolation target device to be replaced, the corresponding CAD drawing is automatically searched and displayed, and the isolation that requires an isolation operation around the isolation target device on the displayed CAD drawing. When the range is determined on a trial and error basis, and the operation status of the device to be operated in the determined isolation range is determined, a hand-drawn status display figure indicating the operation status is displayed over the listening symbol, and the isolation status can be seen at a glance. It becomes possible to confirm.
[0012]
In particular, in a CAD drawing in which regular graphics are usually arranged, the distortion of handwritten-style graphics is highly emphasized, and the distinction between device symbol graphics and operation status display graphics can be identified with a sense without staring. The safety of isolation work can be further improved.
[0013]
In the maintenance management method of the present invention, when plan information including an isolation plan drawing is stored,
A saved drawing search step for searching and displaying a saved isolation plan drawing corresponding to the device to be quarantined;
An operation state change step for changing the operation state of the operation target device as necessary on the isolation plan drawing,
A plan drawing change step for changing a handwritten-like state display figure in response to a change in the operation state of the operation target device;
A save step for saving plan information including an isolation plan drawing that has been changed by a confirm operation;
It is provided with.
[0014]
For this reason, once the plan information including the isolation plan drawing is created and saved for a specific device to be isolated, the saved isolation plan drawing is searched and displayed for the subsequent items, and the operation target is operated as necessary. It is only necessary to change the operation state of the device, and quick and reliable isolation operation can be performed by utilizing the stored maintenance management assets.
[0015]
Here, the drawing retrieval step acquires and displays a CAD drawing including the device to be isolated from the drawing management server by inputting a device number, a device name, or a drawing name.
[0016]
In the operation state setting step, when the operation target device on the drawing is clicked, the isolation range is determined with the next operation target device connected to the clicked operation target device as a terminal device.
[0017]
Specifically, in the operation state setting step, when the operation device on the drawing is clicked, the next operation target device connected by piping to the operation target device is referred to as a termination device table registered in advance as a termination device. The terminal device corresponding to the clicked operation target device is recognized to determine the isolation range.
[0018]
For this reason, when an operation target device is clicked around the device to be isolated on the CAD drawing displayed on the screen, another device connected to the pipe is automatically selected and displayed, for example, in a different color. Thus, the isolation range can be efficiently determined by trial and error.
[0019]
The operation state setting step displays a list of operation target devices included in the determined isolation range, and inputs and sets the operation state in this list.
[0020]
In the plan drawing creation step, a figure handwritten by a person is registered in a primitive figure of the CAD system, and is read and displayed as a handwritten-like state display figure. In the planned drawing creation step, a predetermined fluctuation may be randomly given to the basic figure to create and display a handwritten state display figure.
[0021]
The planned drawing creation step creates and displays a handwritten-like state display graphic with reference to the isolation state definition table in which the state name of the operating device and the identification flag of the state display graphic are registered in advance.
[0022]
In the plan drawing creation step, when the operation device is a valve, a handwritten-like state display figure of circle, triangle and cross is created and displayed corresponding to full open, intermediate open and full close of the valve.
[0023]
The saving step verifies the isolation range with reference to a terminal device table in which the next operation device connected to the operation target device by pipe connection is registered in advance as a terminal device, and displays whether the isolation range is excessive or insufficient. This automatic verification function makes the isolation range more reliable.
[0024]
The present invention provides a maintenance management program for creating an isolation plan to be used for an operation of isolating a specific device during a repair inspection of a plant. This program
On the computer,
A drawing search step for searching and displaying a drawing including a specific device to be isolated in the plant;

[0029]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 2 is an explanatory diagram of a system configuration according to the present invention. In FIG. 2, the maintenance management system of the present invention is installed in a plant such as a nuclear facility. As a system configuration, the drawing management server 12 and the maintenance management database server are connected to the maintenance management client 10 via a network such as a LAN. 14 and a data collection system server 16 provided for the plant.
[0030]
The maintenance management client 10 realizes a function as a maintenance management system according to the present invention, and is used for an operation for isolating a specific device at the time of repair inspection and periodic inspection when a plant device fails. Create an isolation plan. This isolation plan is composed of an isolation plan drawing using a CAD drawing and an isolation vote.
[0031]
The drawing management server 12 stores and manages the CAD drawings of the plant to be maintained and information on various devices. For this reason, the maintenance management client 10 can search and display a CAD drawing including a device to be replaced at the time of failure or inspection by accessing the drawing management server 12.
[0032]
The maintenance management database server 14 stores and manages various maintenance management data including an isolation plan created by the maintenance management client 10 that constructs the maintenance management system of the present invention as a database.
[0033]
Further, the data collection system server 16 performs record management of data collection by various sensors provided in the plant to be maintained and managed. Data collected by the data collection system server 16 is used for display control of a client or a monitoring panel that performs centralized management of the plant.
[0034]
FIG. 3 is a block diagram of the functional configuration of the maintenance management system according to the present invention, which is shown together with the drawing management server 12 and the maintenance management database server 14 connected via the network 18.
[0035]
In FIG. 3, the maintenance management system 11 of the present invention comprises a maintenance management client 10 and various tables necessary for maintenance management. The maintenance management client 10 includes a device table 20, a device / drawing conversion table 22, a drawing number / drawing name conversion table 24, a terminal device table 26, an isolation state definition table 28, for creating an isolation plan according to the present invention. A status display graphic table 30, an execution plan table 32, and an execution plan detail table 34 are provided. Details of these tables will be made clear later.
[0036]
The function of the maintenance management client 10 includes a new creation unit 36 and a result reference creation unit 38. The new creation unit 36 operates when an isolation plan is first created for a specific device to be isolated. The result reference creation unit 38 operates when an isolation plan has already been created and stored for a specific device to be isolated.
[0037]
The new creation unit 36 includes a drawing search unit 40, an operation state setting unit 42, a plan drawing creation unit 44, and a storage unit 46. The drawing retrieval unit 40 retrieves and displays a CAD drawing including an isolation target device that is a target of failure or maintenance inspection.
[0038]
The operation state setting unit 42 determines an isolation range to be isolated on the CAD drawing displayed by drawing search, and each operation target device existing in the isolation range has an operation state for isolation, for example, a valve. Set the valve open or closed.
[0039]
The plan drawing creation unit 44 creates an isolation plan drawing in which a hand-drawn state display graphic is displayed superimposed on a device symbol in accordance with the operation state of the operation target device set by the operation state setting unit 42. . The storage unit 46 stores the plan information including the isolation plan drawing by the confirmation operation in the isolation form file 58 and the isolation plan drawing file 60 provided in the maintenance management database server 14.
[0040]
The record reference creation unit 38 includes a saved drawing search unit 48, an operation state change unit 50, and a plan drawing change unit 52. The saved drawing retrieval unit 48 retrieves and displays a saved isolation plan drawing corresponding to the isolation target device to be subjected to failure or maintenance inspection.
[0041]
In this search, the maintenance management database server 14 is accessed, the corresponding isolation vote is read from the isolation vote file 58, and the target isolation plan drawing is simultaneously read from the isolation plan drawing file 60.
[0042]
The operation state changing unit 50 changes the setting of the operation state of the operation target device as needed on the stored isolation plan drawing displayed by search. Of course, if there is no change in the stored isolation plan drawing and the operation state of the current operation target device, the operation state is not changed and the stored isolation plan drawing is used as it is.
[0043]
The plan drawing change unit 52 changes the handwritten-style state display graphic in response to the change in setting of the operation state of the operation target device. Of course, in the result reference creation unit 38, when a confirmation operation is performed, the storage unit 46 of the new creation unit 36 is operated, and the modified isolation plan drawing and the isolation form corresponding thereto are stored in the maintenance management database server 14. The configuration plan drawing file 60 and the isolation form file 58 are stored.
[0044]
FIG. 4 is a flowchart of an isolation plan drawing creation process according to the maintenance management method of the present invention that functions as the maintenance management system 11 of FIG.
[0045]
In FIG. 4, the processing of steps S1 to S3 and S5 to S7 is the processing of the new creation unit 36 provided in the maintenance management client 10 of FIG. Further, the processing of steps S1, S4, S5 to S7 is the processing of the result reference creation unit 38 in the maintenance management client 10 of FIG.
[0046]
First, if it is determined in step S1 that a new product has been created, the process proceeds to step S2, and a drawing including a device to be isolated that is a target of repair or maintenance inspection is retrieved and displayed. Subsequently, in step S2, the isolation range for performing the isolation operation on the display drawing is determined by trial and error.
[0047]
If the isolation range is determined, an operation state for isolation is set for the operation target device existing in the isolation range in step S5. Subsequently, in step S6, an isolation plan drawing in which handwritten style display graphics, for example, “O”, “△”, and “X” in a handwritten style are displayed on the equipment symbol in correspondence with the operating state of the operation target device. Create In step S7, based on the confirmation operation, the created isolation plan drawing is stored together with the corresponding isolation form.
[0048]
On the other hand, if the result reference creation is determined in step S1, the process proceeds to step S4, and the stored isolation plan drawing corresponding to the isolation target crisis that is the object of repair or maintenance and its isolation form are searched. Display the saved drawing. In this saved drawing, a handwritten-like status display figure is displayed over the device symbol for the operation target device in the isolation range created last time, and if it is necessary to change the operation state of the operation target device, In S5, the setting of the operation state is changed.
[0049]
When the operation state setting is changed, in step S6, a plan drawing is created by changing the handwritten-style state display graphic corresponding to the changed operation state. Finally, in step S7, a new isolation plan drawing created by correcting and changing the stored isolation plan drawing based on the confirmation operation is saved together with the corresponding isolation form.
[0050]
FIG. 5 is a specific example of the state display drawing 62 used as the isolation plan drawing created according to the maintenance management system 11 of FIG. 3 and the flowchart of FIG.
[0051]
In FIG. 5, this state display drawing 62 is an example of an isolation plan drawing for maintenance and inspection, and a portion indicated by a broken line represents a color-isolated isolation range, and an operation target such as a valve existing in this isolation range. For the device, handwritten-style “◯”, “Δ”, and “×” are superimposed on the device symbol as graphics representing the operation state for isolation.
[0052]
The highlighted state by the handwritten-like state display graphic can clearly distinguish the operation target device from the device symbol of the CAD drawing and can be confirmed at a glance.
[0053]
FIG. 6 is a specific example of the device table 20 of FIG. 3, and takes the case of creating the state display drawing 62 of FIG. The device table 20 is composed of three pieces of information: a device number, a device name, and a steady state code. In this example, three types of test valves, test measuring instruments, and test pumps are shown. The steady state codes of the test valves and test measuring instruments are “OP” indicating full open, and the test pumps indicate operating conditions. The steady state code is “ON”.
[0054]
FIG. 7 is a specific example of the device / drawing conversion table 22 of FIG. The device / drawing conversion table 22 includes a device number and a drawing number. For this reason, by designating the device number, it is possible to recognize the drawing number including the designated device and to search and display the CAD drawing including the designated device.
[0055]
FIG. 8 is a diagram number / drawing name conversion table 24 of FIG. 3, in which drawing names are registered corresponding to the drawing numbers. For this reason, after the drawing number is searched from the device number by the device / drawing conversion table 22 in FIG. 7, the drawing number / drawing name conversion table 24 is referred to by the searched drawing number, and the corresponding drawing name is acquired. As a result, the target drawing can be read from the CAD drawing file 56 on the drawing management server 12 side.
[0056]
FIG. 9 is an explanatory diagram of the terminal device table 26 of FIG. This terminal device table 26 is used when automatically determining an isolation range for isolation on a CAD drawing. In other words, in the terminal device table 26, when a specific operation target device is clicked, it is defined to which device connected by piping the range of isolation is expanded.
[0057]
In this example, a model code “TST1” meaning a valve is defined as a model code. Therefore, when a specific device is clicked on the CAD drawing, a process of automatically extending the isolation range to the next valve connected by piping according to the definition of the terminal device table 26 is executed.
[0058]
The terminal device table 26 is used not only for determining the isolation range on the CAD drawing but also for verification when the isolation plan drawing is created and confirmed and saved.
[0059]
That is, the isolation range on the CAD drawing is determined by trial and error while maintenance personnel look at the drawing on the screen, and since it is an artificial process, the range is always determined according to the definition of the terminal device table. May not have been done.
[0060]
Therefore, before saving the isolation plan drawing by the confirmation operation, the definition of the termination device table 26 is applied to the isolation range determined on the CAD drawing and verified. For example, normalization is displayed on the drawing to prompt confirmation by maintenance personnel.
[0061]
FIG. 10 is an explanatory diagram of the isolation state definition table 28 of FIG. The isolation state definition table 28 includes a state code, a state name, and a state display graphic flag. In the case of a valve, the status code is OP open, MD intermediate open, and CL closed. As for the pump, ON is on (operation) and OF is off (stop).
[0062]
The state display graphic flag is 0 for handwritten style “◯”, 1 for handwritten style “Δ”, and 2 for handwritten style “X”. It can be seen that, for example, a steady state code in the device table 20 of FIG. 6 and an IL state code and a recovery state code in the implementation plan detail table 34 of FIG. 13 are set according to the contents of the isolation state definition table 28.
[0063]
FIG. 11 is an explanatory diagram of the state display graphic table 30 of FIG. In this state display graphic table 30, handwritten-like basic state figures 30-1, 30-2, 30-3 corresponding to the state display graphic flags 0, 1, 2 of the isolation state definition table 28 of FIG. It is registered as a primitive figure of CAD.
[0064]
As for this primitive figure, basic state figures 30-1 to 30-3 are registered as figure information normalized to “1.0 × 1.0” by dividing the state into “open”, “intermediate open”, and “closed”. Has been.
[0065]
As shown in the state display drawing 62 of FIG. 5, the handwritten-like basic state figures 30-1 to 30-3 are enlarged and reduced in accordance with the size of the device symbol for which the operation state is set, and are superimposed on the device symbol. Displayed together.
[0066]
The handwritten style basic state figures 30-1 to 30-3 in FIG. 11 can be realized by the following two methods.
(1) A figure actually handwritten by hand is registered as a primitive figure of a CAD system.
(2) A certain amount of fluctuation is randomly given to a basic figure, and a handwritten-like figure is generated and displayed in real time.
[0067]
Of these, when the hand-drawn figure by the person of (1) is used, all the same hand-drawn-like figures are obtained. However, in the case of generating in real time with random fluctuations of (2), the same CAD drawing is the same. Even in the case of a graphic, a random fluctuation occurs for each symbol, resulting in a different graphic, and the emphasis as a handwritten graphic can be further enhanced. The process of generating a handwritten style figure by randomly giving a certain amount of fluctuation to the basic figure in (2) will be clarified in later explanation.
[0068]
FIG. 12 is an explanatory diagram of the execution plan table 32 of FIG. The implementation plan table 32 is a table corresponding to the header of the isolation vote, and is data that is searched for when creating a result reference, and is not referenced when creating a new record. The execution plan table 32 includes an IL management number (isolation management number), a subject, a planner name, a planning date, a planning start date, and a planning end date.
[0069]
FIG. 13 is an implementation plan detail table of FIG. 34 It is explanatory drawing of. This execution plan detail table 34 Is a table corresponding to the data part of the isolation vote, which is searched when referring to the results and is not referred to when newly creating.
[0070]
Implementation plan details table 34 Consists of an IL management number, an equipment serial number, an IL equipment number, an IL status code, and a recovery status code, and corresponds to the status display drawing 62 shown in FIG. 5 in this example.
[0071]
FIG. 14 is a flowchart of a specific processing procedure according to the present invention for creating the isolation plan drawing shown as the state display drawing 62 in FIG. 5. This flowchart is a new creation unit 36 of the maintenance management client 10 in FIG. And the program which implement | achieves the function of the results reference preparation part 38 is comprised.
[0072]
In FIG. 14, first, in step S1, the menu screen 64 of FIG. 15 is opened, and a new plan 66 in “isolation management” is selected and clicked. This click opens the new creation screen 68 of FIG.
[0073]
Subsequently, the maintenance staff checks whether or not it is a new creation in step S2, and if it is a new creation, proceeds to step S3, clicks the target drawing list 70 in the lower right of the new creation screen 68 in FIG. A search screen 74 is displayed.
[0074]
The drawing search screen 74 is provided with input boxes for drawing name 76, target device number 78, and target device name 80. When a necessary item is input in step S4 and the search button is pressed, 18 target drawing list screen 82 opens. In this case, “test drawing” is entered as the drawing name 76 on the drawing search screen 74 in FIG. 17 and the search button 80 is clicked.
[0075]
Subsequently, in step S5, for example, when “test drawing 2” is selected from the target drawing list screen 82 of FIG. 18 and the drawing confirmation button 84 is clicked, the original drawing 86 as shown in FIG. 19 is called and displayed.
[0076]
Therefore, in step S6, the maintenance staff determines the isolation range for isolation by trial and error with the original drawing 86 of FIG. By determining the isolation range, for example, a range display drawing 88 as shown in FIG. 20 is displayed.
[0077]
In the determination of the isolation range, when the device number of the device displayed in the drawing is clicked, the valves connected to both sides of the clicked device are automatically expanded as the isolation range.
[0078]
For example, when the device number “TST3-999-2” is clicked, the device numbers “TST1-999-4”, “TST1-999-5”, “TST1-999-5V”, and “TST1-” indicating the valves connected to the pipes are clicked. The isolation range automatically expands to “999-6” and “TST1-999-7”. This automatic expansion of the isolation range is performed based on the contents of the terminal device table 26 shown in FIG.
[0079]
If the isolation range is determined in step S6, the process proceeds to step S11, and the device information operation screen 90 as shown in FIG. 21 is opened by selecting and clicking a device to be isolated in the isolation range. Therefore, the process proceeds to step S12, and the isolation state is designated as necessary for the devices listed on the device information operation screen 90.
[0080]
After the setting of the isolation state on the device information operation screen 90 is completed, when the OK button 91 is clicked, according to the designation of the isolation state, the state display in FIG. A drawing 62 is displayed.
[0081]
When the isolation plan drawing in which the handwritten-like state display figure is superimposed on the device symbol can be created in this way, the dialog is opened in step S14 and the list creation button is clicked, as shown in FIG. Then, an isolation form creation screen 94 is opened as an isolation form corresponding to the device in the isolation range in the state display drawing 62 of FIG. 5 and its operation state.
[0082]
Finally, in step S15, when the isot form issuing button 96 on the upper left of the isolation form creation screen 94 is clicked, the data is confirmed, and the status display drawing 92 of FIG. 5 and the isolation form of FIG. 22 are the maintenance management database server. 14 and stored in the isolation form file 58 and the isolation plan drawing file 60, respectively.
[0083]
On the other hand, when the performance reference creation process is performed in the state where the new creation screen 68 of FIG. 16 is opened from the menu screen 64 of FIG. 15 in step S1, the isolation data extraction list 72 provided in the new creation screen 68 is stepped. By selecting and clicking in S7, the result reference screen 98 of FIG. 23 is opened.
[0084]
In this example, the result reference screen 98 is registered with one record that has been newly created, and when this is selected as reference information, the process of operating the copy button 102 is performed in step S8. 24, the isolation form correction screen 102 shown in FIG. 24 is displayed as a creating screen.
[0085]
Therefore, in step S9, when the target drawing list button 106 in the isolation form correction screen 102, which is the creation screen, is selected and operated in step S9, the same target drawing list screen 82 as in FIG. 18 is displayed.
[0086]
Next, in step S10, when a drawing such as “test drawing 2” is selected from the target screen list and the drawing confirmation button 84 is operated, the same isolation range as that in FIG. The state display drawing 62 in which the wind operation state figure is displayed in an overlapping manner with the device symbol is opened.
[0087]
Here, in the state display drawing 62 of FIG. 5, when there is a device whose state is to be changed in the isolation range, when that device is selected and clicked in step S11, device information as shown in FIG. 21 is displayed in step S12. When the operation screen 90 is opened, the isolation state of the device displayed here is changed as necessary, and the OK button 91 is operated, the device symbol corresponding to the change of state is switched to the changed handwritten state display figure. The state display drawing 62 is displayed.
[0088]
When the dialog is opened in step S14 and the list creation button is pressed, the isolation form correction screen 102 shown in FIG. 24 corresponding to the changed operation state is displayed. By clicking the correction end button 104 in the upper left, step S15 The data is confirmed in the same manner as the issuance of the isolation form at the time of new creation, and the corrected state display drawing 62 and the isolation form are transferred to the maintenance management database server 14 side of FIG. 3 and stored.
[0089]
When the confirmation operation is performed in step S15, conditions for expanding the isolation range defined in the terminal device table 26 of FIG. 3 for the isolation range in the state display drawing 62 as shown in FIG. If there is an excess or deficiency in the isolation range that does not conform to the conditions of the terminal device table 26, the part is displayed, for example, as a flicker, and the operator is prompted to confirm.
[0090]
Next, as shown in FIG. 5, in the state display drawing 62, as a handwritten-like state display figure indicating the operation state of isolation according to the device symbol, a certain amount of fluctuation is randomly given to the basic state figure and the handwritten style is displayed. A process for displaying a graphic will be described.
[0091]
FIG. 25 is a flowchart of a handwritten-style graphic creation process. In this embodiment, the characteristics of the Bezier curve are used to generate the fluctuation state graphic. The Bezier curve is an algorithm that can draw a smooth curve passing through a control point if a control point for controlling the curve is determined.
[0092]
In the present invention, a certain amount of fluctuation is given to the control point used to generate the Bezier curve, and a Bezier curve passing through the control point is drawn, so that a handwriting style with a slightly different shape every time it is drawn. A status display figure is generated. Further, when the state display graphic is drawn, a certain amount of deviation is given to the barycentric coordinates of the state display graphic, thereby drawing the state graphic slightly shifted in position for each drawing.
[0093]
Here, a Bezier curve is used to generate the fluctuation state figure, but any curve may be used as long as it can be controlled by control points and can draw a smooth curve.
[0094]
In FIG. 25, first, in step S1, a symbol graphic and a basic state graphic are determined from the acquired device number and open / closed state. That is, the basic symbol “◯” corresponding to the valve symbol and the open state is determined based on the device number. Next, in step S2 of FIG. 25, the center of gravity cs and the size “size” are calculated from the coordinates of the basic figure constituting the symbol figure as shown in step S2 of FIG.
[0095]
Here, the size “size” is the length from the barycenter of the symbol figure to the furthest symbol position, and in this example, size = 3.6.
[0096]
Subsequently, in step S3 of FIG.
[0097]
[Expression 1]

[0098]
(Where rud is a fluctuation vector generated each time by a random number function satisfying | rud | ≦ 1)
Determined by By adding the second term on the right side of this equation to the center of gravity cs, the center of gravity coordinates (cj) are randomly shifted, which causes a shift in the drawing position of the state figure. Subsequently, in step S4, a control point of the state figure is determined by the following equation.
[0099]
[Expression 2]

[0100]
Also in this case, the control point is fluctuated by addition of a random component according to the third term on the right side, and as a result, the state figure is fluctuated.
[0101]
If the control points of the state figure are determined in this way, in step S5, a Bezier curve passing through each control point is drawn and displayed as shown in the state display drawing 62 of FIG. 5 to the user.
[0102]
The processes in steps S3 to S5 in FIG. 25 are processes collectively shown in steps S3 to S5 in FIG.
[0103]
FIG. 27 shows basic state graphic registration data used in the handwritten-style graphic creation processing shown in FIGS. The basic state figures 30-1, 30-2, and 30-3 are prepared for each of the basic state figures “◯” indicating open, “Δ” indicating intermediate open, and “×” indicating close. . The control point coordinates are determined to be 6 points for the basic state graphic 30-1, 6 points for the basic state graphic 30-2, and 5 points for the basic state graphic 30-3.
[0104]
Furthermore, this is the number of Bezier curves for creating the basic state figure: one for the basic state figure 32-1, three for the basic state figure 32-2, and two for the basic state figure 32-3. Each is defined corresponding to a control point.
[0105]
Accordingly, the coordinates of the basic control point are acquired from the data of the basic state figure as shown in FIG. 27, and the control point is fluctuated using the barycentric coordinates and size of the symbol figure as shown in step S4 of FIG. It is possible to generate a state display figure with fluctuation for each.
[0106]
In addition to this, the following method can also be used as a method for giving fluctuation to the state display graphic displayed in such a manner as to be superimposed on the device symbol in the present invention.
(1) Registration of basic state figures by user
Usually, the figure drawn by a person differs depending on the person who draws it, and if the same person draws it, it may be a similar figure. In order to express this feature, a different basic state figure for each user, that is, an actually hand-drawn figure or a basic control point is registered. Then, when reading the isolation form from the maintenance management database server 14 when opening the drawing, the creator is extracted, and the basic state figure corresponding to the creator is selected and used. The status display figure can be displayed over the device symbol.
(2) Registration of basic state figures by importance
By assigning an importance parameter to each device number and registering a basic state figure according to the importance, a state display figure that is more noticeable than usual is drawn for important equipment.
(3) Weighting the size according to importance
By assigning an importance parameter to each device number and adjusting the size parameter according to the importance, the state display graphic of the important device is drawn with a slightly larger size.
[0107]
In addition, this invention is not limited to said embodiment, The appropriate deformation | transformation which does not impair the objective and advantage is included. The present invention is not limited by the numerical values shown in the above embodiments.
