Embodiment 1
The system diagram automatic creation system of the present invention is directed to a system used for a power distribution monitoring and control device that monitors and controls power distribution equipment.
The power reception monitoring control device of the power receiving and receiving monitoring control system such as a factory, a building, and a facility receives a signal notifying the measurement value from the monitoring target device in addition to the failure and the status change of the monitoring target device and notifies the operator. In addition, it is possible to open and close the device from the power reception monitoring control device to a monitoring target device such as a circuit breaker or a disconnect switch.

In order to construct a power reception monitoring control device, signal information for internally processing a signal from a monitoring target device, a power system diagram showing the monitoring target device, and a state of the monitoring target device in the power system diagram In order to indicate the difference between the two, it is necessary to set the behavior.
According to the present invention, the power system diagram described above is automatically created based on a skeleton (single wire connection diagram).
FIG. 1 is an entire configuration diagram of a system diagram automatic creation system according to a first embodiment. Moreover, FIG. 2 is a figure which shows an example of the electric power systematic diagram produced using this system, and FIGS. 3-7 is explanatory drawing explaining the detail of each part of FIG.

First, the entire configuration will be described with reference to FIG.
Prior to the automatic creation of the system diagram, it is assumed that a single-wire diagram of the entire electric device targeted by the power reception and distribution monitoring control device is prepared in advance. This single-line diagram is generally created using a CAD system. Therefore, in the following, a single-wire connection diagram created in advance by a CAD system will be referred to as "CAD data".

  The system diagram automatic creation system is created with CAD data 1 prepared in advance and scan software 2 (hereinafter, abbreviated as scan S / W 2) for creating symbol data (symbol list 3) from CAD data 1 Database creation software 5 (hereinafter referred to as DB creation S /) which creates a system database 6 (hereinafter referred to as system DB 6) from the symbol data (symbol list 3) and the signal information of the prepared device (signal list 4). System diagram creation software 9 (hereinafter, system diagram creation S / W 9) for creating the power system diagram data 10 from the created system DB 6 and the prepared registered symbol list 7 and display range 8 And a display control means 11 for performing control to display a power system diagram based on the created power system diagram data 10 It is. The part surrounded by a dashed-dotted line in the figure is the output from S / W.

Next, details of each part will be described in order.
The CAD data 1 is a single-wire connection diagram of the entire electric device to be monitored, and is created as data readable by scan S / W. Inside CAD data 1, information related to single-line wiring diagram such as font, size, equipment number for distinguishing equipment held by CAD data 1, symbol indicating type of each equipment, position information of each equipment, etc. Is held.
The scan S / W 2 is software that extracts symbols from the CAD data 1 and automatically creates a symbol list 3 as shown in FIG. 3 as symbol data.

  The symbol list 3 of FIG. 3 shows an example of the created symbol data. As shown, the device number 21 and the corresponding symbols 22, coordinates 23, and connected device list 24 are listed. Here, the coordinate 23 is the position coordinate of the symbol which is generated from the position information of each device held inside the CAD data 1. The connected device list 24 indicates the connection status between the devices indicated by the device number, and holds columns by the number of each device number, and the device numbers are arranged from the left in ascending order. The connection status can be confirmed by writing “1” in the column of the corresponding device number if it is connected, and writing “0” if it is not connected.

FIG. 4 shows an example of the signal information to be read by the DB creation S / W 5 together with the created symbol list 3. Specifically, as shown in the signal list 4, the address to be assigned to each symbol is a list It is prepared in advance and stored in this system.
In FIG. 4, the device number 21 corresponds to the device number in FIG. Likewise, corresponding parts are indicated by the same reference numerals.
A device start / stop 25 associated with the device number 21 and indicating whether the device ON / OFF control is possible, a device start / stop destination address 26 which is a transmission signal at the time of start / stop, and conditions for permitting start / stop The device start / stop condition 27 shown, the device name 28 which is a symbol indicating the device name, the device address 29 corresponding to the transmission signal representing a change in the device state, and the ON side representing the symbol state name and symbol color in the ON state The information 30 is composed of the name of the symbol state in the OFF state and the OFF side information 31 representing the symbol color.

Supplementally described, the device start / stop 25 distinguishes whether the signal only displays the current state (ON / OFF) in the power system diagram or a signal that can be controlled ON / OFF by the operator. “0” indicates only display, and “1” indicates that ON / OFF control is possible.
The device start / stop condition 27 is required, for example, when a key lock switch or the like is used, and restricts ON / OFF control of the power facility so that nobody can easily operate it. Is set to “1” when the device is released, and is set to “0” in the locked state. (Note that these logics are built into the system beforehand.)

The DB creation S / W 5 is software for creating the system DB 6 from the symbol list 3 and the signal list 4.
FIG. 5 is a diagram showing an example of the created system DB 6. The contents of the system DB 6 are basically a combination of the symbol list 3 shown in FIG. 3 and the signal list 4 shown in FIG. 4, so the explanation of each item is omitted.

FIG. 6 is a view showing an example of the registered symbol list 7. As shown, the ON-side symbol shape 32 and the OFF-side symbol shape 33 are held as a list for each symbol 22.
The registered symbol list 7 is registered in the present system because the same data can be used each time in the present system.
FIG. 7 is a view showing an example of the display range table 8. As shown in the figure, the number of sheets 34 corresponding to the number of pages of the power system diagram for the power distribution monitoring and control device, the sheet name 35 corresponding to the screen name, and the display device list 36 displayed on each screen. The display device list 36 arranges the device numbers (same as the device number 21 in FIG. 3) sideways, and displays the device to be displayed as “1” and the device not to be displayed as “0”.
The display range table 8 is created in advance and stored in the present system.

System DB 6, registered symbol list 7, display range table 8 are read and summarized as one data, converted to data that can be displayed on screen, and power system diagram data 10 is created as shown in the system diagram creation S / W 9 It is.
The created power system diagram data 10 is data in which information for creating and displaying the “power system diagram” as shown in FIG. 2 is recorded, and the registered symbol is matched with the storage format of the software to be created and displayed. It is file data in which the information in the list 7, the system DB 6, and the display range 8 is rewritten.
The above is the operation until the power system diagram data 10 is created. Power system diagram data 10 can be automatically created by the operator performing input operations of CAD data 1, signal list 4, registered symbol list 7, and display range 8.

Next, based on the generated power system diagram data 10, the display control means 11 automatically displays the power system diagram as shown in FIG. 2 on the display unit of the power reception and distribution monitoring control apparatus as shown in FIG. Do.
FIG. 8 is a flowchart for explaining the entire procedure, and FIGS. 9 to 11 are flowcharts for explaining the internal details of the flowchart of FIG.

A schematic flow up to the display of the power system diagram will be described with reference to FIG.
In step 1 (hereinafter abbreviated as S1), processing for creating a new sheet is performed. Next, symbol arrangement processing is performed in S2, symbol setting processing is performed in S3, and finally a system diagram display processing is performed in S4.
9 is a detailed flowchart of S1 of FIG. 8. Similarly, FIG. 10 is a detailed flowchart of S2 of FIG. 8 and FIG. 11 is a detailed flowchart of S3 of FIG.

Then, the process of creating a sheet will be described in more detail with reference to FIG.
At S11, the number of sheets to be created is read. Since data of the display range table as shown in FIG. 7 is read in the power system diagram data 10, the number of sheets 34 in FIG. 7 is read. The number of power system diagrams can be obtained from the number of rows.
Next, a power system diagram page for the maximum number of sheets read is newly created using the system diagram editor or drawing software (S12).
Next, the sheet name 35 is read (S13), and the sheet name 35 of each power system diagram is assigned to each created page (S14).
Although pages for the maximum number of sheets are created, the operator can select which page is displayed after creation.

Next, processing for arranging and drawing symbols will be described with reference to the flowchart of FIG. First, from the data in the display device list 36 (see FIG. 7) of each sheet, the device number to be displayed on each systematic diagram page is read (S21), and then from the data in the system DB 6 and registered symbol list 7 The symbol 22 corresponding to each device is read (S22). Then, the read symbol 22 is placed at the position of the coordinate 23 of the system DB 6 (S23).
The symbol 22 arranges both the ON side symbol shape 32 and the OFF side symbol shape 33. However, when displaying normally, the current state is confirmed, and if it is the ON side state, the information related to the ON side Is displayed, and all information related to the OFF side is not displayed. On the contrary, in the case of the OFF side state, the information related to the OFF side is displayed, and all the information related to the ON side is not displayed.

Next, the connected device is searched from the connected device list 24 of the arranged device number 21, and it is checked whether or not it is drawn in the power system diagram (S24). If it is drawn (YES), the symbols of the corresponding equipment number 21 are connected by a line (S25). The connections are, for example, connected by one straight line if the X-axis coordinates are the same, and otherwise connected by combining two or three straight lines at right angles.
Next, the device name 28 is read (S26).
Next, the read device names are arranged in the system diagram. Specifically, the device name 28 is arranged on the right or left side of the symbol 22 so as not to overlap with the straight line connecting the symbols 22 arranged in the power system diagram (S27).

When the arrangement and connection of symbols are completed, the process proceeds to the symbol setting process of S3 described in FIG. 8, that is, the process of setting the behavior for the arranged symbols. The details will be described with reference to the flowchart of FIG. .
In FIG. 11, first, the device start / stop 25, the device start / stop destination address 26, the device start / stop condition 27, and the device address 29 are assigned to the symbols 22 arranged in the power system diagram (S31).
Next, the ON side information 30 and the OFF side information 31 are assigned (S32).

In the power distribution monitoring and control apparatus, the operator is notified that the state of the symbols 22 arranged in the power system diagram has changed.
By assigning the ON-side information 30, when the corresponding symbol 22 is turned ON, the color of the symbol 22 is read from the symbol color and displayed. Further, when notifying the operator, the state of the symbol 22 can be read from the name and displayed.
By allocating the OFF side information, when the corresponding symbol 22 is turned OFF, the color of the symbol 22 is read from the symbol color and displayed. Further, when notifying the operator, the state of the symbol 22 can be read from the name and displayed.

  Finally, an image is output to display a systematic diagram (S4 in the flow of FIG. 8). Thus, a power system diagram of the power reception and distribution monitoring control device can be automatically generated.

In the above description, the case where the ON side / OFF side information of FIG. 11 is consistently assigned is described, but how much information is allocated and displayed on the power system diagram displayed on the distribution monitoring and control device The display control means 11 enables the operator to select whether to use the power system diagram according to the application of the power system diagram.
For example, if it is not necessary to set the behavior to change the state of the signal, the procedure of FIG. 11 may be omitted. As a result, the display speed can be increased, and only necessary information can be displayed efficiently.
In addition, the operations described above with reference to the flowcharts of FIGS. 8 to 11 automatically read the generated power system diagram data 10 when the operator starts the system, and the display of the power system diagram is automatically performed. Ru.

As described above, according to the system diagram automatic creation system of the first embodiment, the system diagram automatic creation system automatically creates display data of the power system diagram used in the power receiving and distribution monitoring control device, Scan software for reading symbol data of devices described in the single-wire diagram by reading the single-wire diagram created in advance using a CAD system, and creating symbol data, symbol data created, and devices prepared in advance A power system that can be displayed as a power system diagram by reading database creation software for creating a system database from signal information, and the created system database, registered registration symbol list and display range table prepared in advance Since it has system diagram creation software for creating diagram data, it is created by CAD Power system diagram data that can be displayed as a power system diagram can be automatically created from a single-line diagram, thereby reducing the operation cost required to create the power system diagram and the test cost for testing the created power system diagram . In addition, it is possible to reduce input errors when creating a power system diagram.
In addition, since the data of the display range is included, as shown in the whole system diagram and the partial system diagram, it is possible to divide and display as needed.
From these, it is possible to construct an inexpensive and highly reliable supervisory control device.

  In addition, it has display control means for displaying a power system diagram based on the created power system diagram data, and the display control means automatically allocates signal information based on the signal information read in the power system diagram data. Since this is done, signal information such as start / stop and start / stop conditions can be displayed in association with the devices arranged in the created power system diagram.

  In addition, since the setting of behavior to change the state of the assigned signal is automatically performed on the symbols of the power system diagram to be displayed, whether the placed device is in the ON side or in the OFF side Since the display of the symbol can be changed, the operator can easily know the state of the symbol.
