  Next, the operation of the screen display control data generation device 30 will be described. Here, the case where the screen display control data of the equipment monitoring screen is generated by using the power system diagram (single line connection diagram) shown in FIG. 2 as the original diagram 9 (paper original diagram 9a) will be described as an example. In general, a power system diagram shows a control circuit for instrumentation control and a ground line in addition to a main circuit portion through which a power supply current flows. In addition, equipment such as transformers and circuit breakers constituting the circuit are represented by electrical symbols defined in JIS C0617 and JISIA 118-1, and the names and specifications of the equipment are also appended. For example, as shown in FIG. 2, on the right side of the disconnector 75 displayed with a predetermined electrical symbol, “DS”, “DV-RB”, “3” in addition to “89M1R” which is the name of the device. .6 kV 600 A ”,“ 20 kA ”and the like are described.

  Of the devices described in the paper original drawing 9a of FIG. 2, the devices described in the screen format FIG. 3 are listed. In the first system (left system) connected to 52M1, between the cable head 71 and the cable head 72, there are an electric wire 73, a disconnect switch 75, a load switch 76, a transformer 77, a measured value 78, a measured value 79, and a measured value. The value 80, protective relay 81, protective relay 82, and protective relay 83 are described. In the second system (right system) connected to 52M2, between the cable head 91 and the cable head 92, there are an electric wire 93, a disconnector 95, a disconnector 96, a transformer 97, a measured value 98, a measured value 99, and a measured value. 100, protective relay 101, protective relay 102, and protective relay 103 are described. FIG. 2 also shows an electric wire 74 that connects the electric wire 73 and the electric wire 93.

  The original drawing 9 such as the power system diagram provided by the orderer is read by the original drawing input processing unit 1 to generate the original drawing data 15 (original drawing data generation step). The original drawing data 15 is stored in a recording device or a recording medium. At this time, a paper original diagram 9a which is a printed power system diagram provided with the original diagram 9 is read by the scanner device 16 and stored as original diagram data 15 which is image data. When the provided system diagram is a data file such as CAD data (CAD data file 9b), it is input to the CAD terminal device 17 and stored as it is. The CAD terminal device 17 generates original drawing data 15 that is an image of the original drawing from the CAD data file 9b. If the provided CAD data file 9b is an imaged system diagram or the like, it has already been imaged and is used as it is.

  Next, the original drawing edit processing unit 2 edits and generates the screen format figure 3 and variable image symbol attribute information 18 necessary for displaying the equipment monitoring screen from the saved original drawing data 15 (previous data generation step). The variable image symbol attribute information 18 (see FIG. 5) generated by the original drawing edit processing unit 2 is data in which an item number associated with a monitoring control item of the target device described later is not registered, and is a screen control data generation processing unit. 6 is completed, the variable image symbol attribute information 18a (see FIG. 6) in which the item numbers are registered is completed. The monitoring control item is a notation that summarizes the monitoring target item and the control target item. The monitoring control item is a monitoring target item for monitoring, and is also a control target item for control.

  The editing processing unit 2 extracts a necessary part as an equipment monitoring screen from the original drawing data 15 to create an initial screen format diagram, and the variable of the screen variable image symbol data 4 representing the state of the monitored device in the initial screen format diagram. The screen symbols shown in FIG. 4 are generated by arranging the image symbols. When the original drawing editing processing unit 2 extracts a necessary part for the equipment monitoring screen from the original drawing data 15, the screen variable image symbol data 4 is created in advance as a symbol extraction table. An example of the symbol extraction table is shown in FIG. The symbol extraction table is data obtained by converting the screen variable image symbol data 4 into a table format.

  The screen variable image symbol data 4 shown in FIG. 3 will be described. The table of the screen variable image symbol data 4 has columns (columns) for names, graphic symbols on the original drawing, variable image symbols, display color when on, display color when off. The information registered in the column (row) of the display color when on and the display color when off is the change information. Depending on the variable image symbol, the on-time display color is read as an energized display color or an operating display color. The off-time display color is also read as a cut-off display color or a non-operating display color depending on the variable image symbol. In the name column, six devices are shown. In the third stage, since the variable image symbols are the same, the disconnect switch and the load switch are shown together. The first stage is a cable head. The graphic symbols and variable image symbols on the original drawing are two downwards and upwards, respectively. The variable image symbol of the cable head does not change color.

  The second stage is a circuit breaker and shows two types of graphic symbols on the original drawing. The variable image symbol is a common symbol even in the circuit breaker of (1) and the circuit breaker of (2). In the case of a circuit breaker, the on-time display color and the off-time display color mean the display color when energized and the display color when interrupted. The variable image symbol of the circuit breaker changes to red and green, respectively, when it is on and when it is off (when energized and when it is shut off).

  The third stage is a disconnector and a load switch. The symbol on the original drawing of (1) is a disconnector, and the symbol on the original drawing of (2) is a load switch. The variable image symbol is a common symbol even in the disconnect switch of (1) and the load switch of (2). In the case of a disconnector and a load switch, the display color when on and the display color when off mean the display color when energized and the display color when shut off. The variable image symbols of the disconnecting switch and the load switch change to red and green, respectively, in the on-time table and in the off-time (when energized and shut off).

  The fourth stage is a transformer. Two graphic symbols and variable image symbols are shown on the original drawing. The variable image symbol of the transformer does not change color. The fifth level is a protective relay. Four graphic symbols and variable image symbols on the original drawing are shown. In the case of a protective relay, the on-time display color and the off-time display color mean the display color during operation and the display color during non-operation. The variable image symbol of the protective relay changes to red and unlit (background color), respectively, in the on-time table and in the off-time (operating and non-operating).

  The sixth level is the measured value. The graphic symbol and the variable image symbol on the original drawing each show two values, a current value and a voltage value. In the case of measurement values, the display color when on and the display color when off are the meanings of the display color when operating and the display color when not operating (unmeasured). The variable symbol of the measured value displays the value of the measuring instrument when it is on (during operation), and when the numerical value is normal, the numerical value turns white, and when the numerical value is abnormal, the numerical value Turns red. When the variable image symbol of the measured value is off (during non-operation), the display symbol “***” is displayed and the display symbol changes to red.

  The processing procedure of the original drawing edit processing unit 2, that is, the previous stage data generation process will be described. Screen Format in FIG. 4 The processing procedure of the original drawing editing processing unit 2 will be described by taking as an example the case where the variable image symbol attribute information 18 in FIGS. 3 and 5 is generated. First, as step S001, the original drawing data 15 of the original drawing 9 and the graphic symbols (registered drawing symbols) of the respective devices registered in the screen variable image symbol data 4 are collated, and each device described in the original drawing data 15 is checked. Graphic symbols (original graphic symbols) are extracted (graphic symbol extraction step). The graphic symbols extracted in the paper original drawing 9a of FIG. 2 are the cable heads 71, 72, 91, 92, the disconnectors 75, 95, the load switches 76, 96, the transformers 77, 97, and the measured values 78, 79, 80. , 98, 99, 100, and protective relays 81, 82, 83, 101, 102, 103.

  In step S002, paying attention to the four types of graphic symbols extracted from step S001: cable head, circuit breaker, disconnector, and transformer, connection extending from the cable head 71, 72, 91, 92 to each device Only the lines (electric wires 73, 74, 93) are extracted, and the other connection lines are deleted. The extracted connection lines (electric wires 73, 74, 93) correspond to the power supply main circuit to be drawn as a screen format diagram (main circuit extraction step).

  As a step S003, among the graphic symbols extracted in the step S001, for the circuit breakers, disconnectors 75 and 95, and load switches 76 and 96, a character string drawn in the vicinity of the extracted graphic symbols (a group of characters without division) A character string (89M1R, etc.) starting with 52 is extracted from the set), and a breaker or load switch is started with 89, and the others are deleted (character string arranging step). In FIG. 2, there is no circuit breaker. In FIG. 2, since there are two disconnectors 75 and 95 and two load switches 76 and 96, “89M1R”, “89T1”, “89M2R”, and “89T2” in the respective disconnectors and load switches. Only the character string of is left, and other character strings are deleted.

  In step S004, the graphic symbol extracted in step S001 is replaced with variable image symbol data corresponding to each graphic symbol in accordance with the screen variable image symbol data 4 (variable image symbol replacing step). The cable heads 71, 72, 91, 92 in the original paper 9a of FIG. 2 are replaced with the cable heads 31, 32, 51, 52 in the screen format FIG. 3 of FIG. Similarly, the disconnectors 75 and 95 and the load switches 76 and 96 in the original paper 9a are replaced with the disconnectors 35 and 55 and the load switches 36 and 56 in the screen format FIG. 3, respectively. The transformers 77 and 97 in FIG. 9a are replaced with the transformers 37 and 57 in the screen format FIG. 3, respectively. The measured values 78, 79, 80, 98, 99, 100 in the original paper 9a are replaced with the measured values 38, 39, 40, 58, 59, 60 in the screen format FIG. The protective relays 81, 82, 83, 101, 102, and 103 in the paper original drawing 9a are respectively replaced with the protective relays 41, 42, 43, 61, 62, and 63 in the screen format FIG.

  When executing step S004, the operator displays a screen format diagram in the middle of the work on the CAD terminal device 17 to add the name of the power transmission destination circuit or the like, or to narrow down the range to be displayed on one screen. Work may be performed (adjustment process).

  In step S005, the screen data completed by executing steps S001 to S0004 is saved as the screen format FIG. 3 in which the variable image symbols are arranged (screen format diagram saving step). The storage destination is a recording device, a recording medium, or the like. Steps S001 to S0005 are screen format diagram generation steps.

  FIG. 4 shows an example of the screen format shown in FIG. 3 that is automatically generated from the system diagram of the original paper sheet 9a shown in FIG. 2 according to the processing procedure of steps S001 to S0005. In this screen format FIG. 3, the electric wires 73, 74, and 93 shown on the original system diagram are shown as electric wires 33, 34, and 53, and the graphic symbols shown on the original system diagram are displayed. Of these, those that match the graphic symbols specified in the screen variable image symbol data 4 are respectively replaced with the data of the variable image symbols. Note that the same screen format as FIG. 3 shown in FIG. 4 is displayed as the equipment monitoring screen of the equipment monitoring control system 20. The facility monitoring screen includes a fixed-image graphic screen that represents a relationship between a plurality of monitoring target devices in the monitoring target facility, and a variable image symbol that changes according to the state of the monitoring target device.

  In step S006, the original drawing editing processing unit 2 generates variable image symbol attribute information 18 as shown in FIG. 5 based on the screen format FIG. 3 in which the variable image symbol is arranged and the screen variable image symbol data 4. .

In the information registration field (column) provided in the variable image symbol attribute information 18, attribute information such as the type of each symbol, the coordinates on the screen, and the display color corresponding to the data of each variable image symbol is automatically registered. (Attribute information generation step). The variable image symbol attribute information 18 is stored in a recording device, a recording medium, or the like. The variable image symbol attribute information 18 shown in FIG. 5 includes numbered (No.) columns (columns), coordinates, picture names, symbol types, item numbers, on / off color, and failure color. Information registration fields (columns) are provided, and each piece of attribute information can be registered. In the variable image symbol attribute information 18 shown in FIG. 5, items other than the item numbers associated with the monitoring control items of the target device are automatically registered based on the screen format FIG. 3 and the screen variable image symbol data 4. However, the item number associated with each symbol and the monitoring control item is not registered. The item number registration is performed by the screen control data generation processing unit 6. Note that, in the column (column) of “additional codes on the drawing” in FIG. 5, the symbols attached to the variable image symbols in the screen format FIG. 3 of FIG. 4 are described for convenience so that the correspondence can be easily understood.

  The screen control data generation processing unit 6 executes a control data generation process for generating screen display control data 7 by executing an item number registration process and a final data generation process described below. The item number registration process and the final data generation process will be described. In the screen control data generation processing unit 6, an associating operation for assigning an item number associated with a monitoring control item to variable image symbol data that has not been performed in the processing of the original drawing editing processing unit 2 (previous stage data generation step), that is, an item Number registration work is performed (item number registration process).
