A mode for carrying out the invention is shown below. The drawing system 1 of the present embodiment is used for drawing a high-voltage power receiving facility, a distribution board, a distribution board, or a control board. Further, the drawing system 1 is specified by the device specifying means 13 for specifying the type of the device from the image data of at least one of the symbol and the character indicating the device and the device specifying means 13 in the two-dimensional drawing which is the input information. It includes a position information acquisition means 14 for acquiring position information on the Cartesian coordinate system of the device, and a role specifying means 15 for identifying the role of the device from the device and the position information specified by the device specifying means 13. Therefore, it is possible to save the trouble of rewriting the drawing and reduce the drawing production time and the labor cost.

The device identifying means 13 is connected to a storage unit 18 in which at least one of data of a plurality of patterns of symbols and characters indicating the device is recorded in a state of being associated with the type information of the device, and is based on the image data. It is preferable to specify the type of device by referring to the storage unit 18 from the input data.

Here, the overall picture of the drawing system 1 in the embodiment will be described. As can be understood from FIG. 1, the drawing system 1 includes an image data reading means 11 for reading a figure created by the requester, an image recognition means 12 for recognizing the read figure, and an image recognition means. A device identifying means 13 that identifies the type of device using the information recognized by 12, a position information acquiring means 14 that can grasp the positional relationship of a plurality of devices, a role specifying means 15 that estimates the role of the device, and theirs. The connection diagram creating means 16 for creating a connection diagram using the result is provided. Further, the correction means 17 used for correcting an error in the result obtained by the drawing system 1 is provided. Further, the database is provided as a storage unit 18 in which information to be compared with the information recognized by the image recognition means 12 is recorded.

The drawing system 1 can read the image data obtained by scanning a paper drawing such as a handwritten drawing created by the requester or the image data converted to PDF by the image data reading means 11. In this way, unlike the CAD diagram, even if the line or diagram does not have device information or connection information embedded in advance, the drawing system 1 of the embodiment can be used to understand the meaning of the shape and arrangement. It makes it possible to guess what the requester intended. The data format that can be read by the image data reading means 11 is not limited to the above as long as the content intended by the requester can be inferred. For example, it may be capable of reading CAD diagram data.

An example of the flow when using this drawing system 1 will be briefly described. In the example shown in FIG. 2, image data is read based on the material provided by the requester (S001). A database is referred to in order to identify the type of device included in the read image data (S002). The type of device is specified from the referenced result (S003).

In addition, the position information of the device whose type is specified is specified (S004). The role of the device is specified from the type and position of the device specified in steps 003 and 004 (S005). When the role of each device is estimated, a line is drawn so that the role of each device can be played (S006). Drawing in this way eliminates the need for a person to create a drawing from scratch based on the materials provided by the client.

Here, an example of specifying the type of device will be described. The drawing sent from the requester describes the symbol and the characters related to the symbol, but even if the same thing is expressed, the symbol and how to express the character are not fixed ( (See FIG. 3). Therefore, the drawing system 1 of the embodiment reads the image data, collates the symbols and characters extracted by the image recognition means 12 with the information recorded in the database, and describes them in the drawing submitted by the requester. Identify the type of device. In the database, the type of device is associated with symbols and characters.

In the embodiment, in order to perform this identification, first, a database symbol and character matching the requesting symbol and character are searched for. That is, it finds matching data rather than similar data. At this time, it is sufficient that at least one of the symbol and the character indicating the device can be read.

There are various ways to write the symbols and characters of the drawings submitted by the requester. Therefore, in the embodiment, various symbols and character patterns are associated with the style symbols and characters represented on the drawing by the drawing system 1 side and stored in the database, and are described in the drawing submitted by the requester. The existing symbols and characters are converted into the style symbols and characters on the system side (see FIGS. 4 and 5). It should be noted that the information shown in FIG. 6 is represented by the notation of characters as shown at the right end of FIG.

The image data of the symbol submitted by the requester may be used as it is for device identification, or may be converted into line information and then used for device identification. For example, the image data of the characters submitted by the requester may be converted into character data by OCR (Optical Character Reader), and the device may be specified by collating with the character data stored in the database.

The stored information in the database may be information stored in advance, or in addition, it may be one that stores the result judged by a person in the process of the actual drawing work and accumulates the data. In the latter case, the judgment in the device-specific system can be made closer to the judgment by a person. If the input information does not match even if the database is referenced, an error determination may be made and the system user may be notified to that effect (see FIG. 7).

By the way, it suffices to find the same data that matches mechanically, but since the symbols and characters of the requesting drawing vary from person to person, it is assumed that they do not match the accumulated data in the database. In order to solve such a situation, the image data or the character data may be determined by the AI trained in various forms of characters as teacher data. (See FIGS. 8 and 9). Even if the data submitted by the requester does not completely match the accumulated data in the database, identifying the device by AI judgment based on the teacher data can further reduce the possibility of errors.

In the embodiment, the device-specific learning means for learning at least one image data (condition item) of a symbol and a character indicating a device and a type (result) of the device representing the image data as teacher data is provided. The "condition item" referred to here is assumed to be various, for example, various patterns of symbols and characters submitted or will be submitted by the requester. The "result" is a symbol or character output at the time of drawing in this system.

If the "condition item" is a symbol submitted or will be submitted by the requester, the "result" is the corresponding symbol output by the system. If the "condition item" is a character submitted or will be submitted by the requester, the "result" may be the corresponding symbol and character in the system. In this way, by giving teacher data to the device-specific learning means for learning, the device can be specified by the AI determination even if the requesting symbol or character has various patterns.

If the device type cannot be specified as one as a result of the determination, the error determination may be notified to the system user, or the device candidates may be displayed and the system user may select the device ( (See FIG. 9).

By the way, the device judged by the symbol and the device judged by the character may be different. In this case, in the embodiment, it is preferable to preferentially adopt the determination result from the characters (see FIGS. 10 to 12). This is done because the numerical values of various parameters cannot be specified only by the symbols, and as a past tendency, the symbols are more likely to be incorrect than the characters. It is considered that this is due to forgetting to change the symbol or lack of knowledge about the symbol when the drawing used in the past is diverted. Therefore, when the type of the device specified by the symbol and the type of the device specified by the character are different, the device specifying means 13 is configured to preferentially adopt the type of the device specified by the character. preferable.

In addition, an error determination may be made so that a person can confirm which of the symbol and the character is correct. In the case of a transformer, in the case of internal connection designation, there are cases where the requester intentionally specifies the symbol and the character even if the judgment of the symbol and the character is different. When such a situation is expected, it is preferable to notify the user that the specifications are different from the general specifications.

Here, the role identification performed by the drawing system 1 will be described. Role identification is to identify the relationship between a specific device and another device, such as how it is connected to the other device. Even if the same equipment is used, the roles may be different, so this role identification is important for creating drawings. For example, even if the same LBS (high-voltage AC load switch) has different roles, such as the main circuit breaker and the switch on the secondary side thereof, it is possible to specify which LBS plays which role. Things are done.

Since it is necessary to specify the type of the device as a premise for specifying the role, in the embodiment, the type of the device is specified by the device specifying means 13. Then, the role is specified from the position information of the devices (relative positional relationship between the devices) and the combination of the devices. Therefore, the role specifying means 15 of the embodiment is connected to the storage unit 18 that records the combination of devices, and refers to the relative position information between the specified devices and the combination information of the devices recorded in the storage unit 18. It is configured to identify the role of the device by doing so. When AI is used, it is preferable to provide a role-specific learning means for learning the role of the device based on the combination of the position information of the specified device and the device as teacher data. Regarding the position information, it is preferable to determine the devices having substantially the same value on the X-axis or the Y-axis and use it as one of the judgment factors for specifying the role. In this case, for example, a common x value or y value is searched for between devices.

Here, a specific example of determining the role is shown. For example, in the example shown in FIG. 13, the figure submitted by the requester has four symbols that can be read as LBS and two symbols that can be read as a transformer (TR). In this case, if one TR and one LBS have the same x value, it is determined that the LBS is a primary switch of the TR having the same x value. When one TR and two LBSs have the same x value, the y value is referred to, and the LBS closer to the y value of the TR having the same x value is the primary switch of the TR having the same x value. judge. It should be noted that such a judgment can be similarly made by replacing TR with SC (capacitor), high-voltage magnet, cutout, and CT.

Further, in the example shown in FIG. 14, there are four symbols that can be read as LBS, but when the y value of LBS is acquired, only one position is different, and the remaining three are the same y value. Further, LBS having the same y value has a pair of symbols that can be read as a capacitor (SC) and a transformer (TR) at the same x value, respectively. From the above results, it can be determined that the LBS having the same y value is the primary side switch of the SC and TR paired with the same x value. Further, the only LBS having a different y value can be determined as the main circuit breaker. Such a determination can be made in the same manner even if the LBS is replaced with a VCB (vacuum breaker).

Further, a different determination example will be described. In the example shown in FIG. 15, there are three TR symbols and three VM / AM symbols. In addition, VM means a voltmeter and AM means an ammeter. Although it is a VM / AM paired with a TR, the position of the symbol is the same level of separation as multiple TR symbols, and it is difficult to determine which TR it is paired with. For example, if they are linked in the direction of a shown in FIG. 15, the rightmost VM / AM and the leftmost TR are left over. On the other hand, when linked in the direction of b, no remainder is generated. Therefore, in this case, it can be seen that the b-direction association should be applied.

Here, an example of the determination procedure in such a case will be described. In this case, the role specifying means 15 is arranged so as to be displaced in the X-axis direction at the first y value from the position information of the specified device and the combination information stored in the storage unit 18. It is located so that the device and the second y value, which is different from the first y value, deviate from all the first devices in the X-axis direction, and can be combined with at least one first device from the combination information. Until a combination is found in which all the second devices in the group are combined one-to-one with the first device adjacent to each of the group including the plurality of second devices determined to be. , Repeat the judgment of the combination. If the second device cannot be fully connected to the first device, it is determined that the connection candidate is inappropriate.

In this way, it is possible to correctly connect the paired devices whose symbols are out of alignment without leaving unconnected devices. Further, such a judgment can be similarly judged by replacing TR with LBS and VCB. Similarly, the same judgment can be made by replacing the VM / AM with other measuring instruments or alarms (leakage fire alarms, leakage alarms, thermal relays, fuses, instrument transformers, etc.).

In such a procedure, x and y may be interchanged depending on the drawing configuration. In this case, a plurality of role specifying means 15 are arranged so as to be displaced in the Y-axis direction at the first x value. The first device and the second x value, which is different from the first x value, are located so as to deviate from all the first devices in the Y-axis direction, and from the combination information for at least one first device. A combination in which all the second devices in the group are combined one-to-one with the first device adjacent to each of the group including the plurality of second devices determined to be able to be combined. The combination judgment may be repeated until is found.

It should be noted that the selection contents may be modified at each stage, but in the embodiment, the modification can be performed even after the device is specified and the role is specified. In the example shown in FIG. 16, when it is determined after the role identification is completed, "there is a difference between the recommended value of each numerical value in the combination of devices recorded in the database and the read value", the numerical value. Is modified to match the database side. Such corrections may be made automatically or after taking the confirmation step. In addition, the notation method at the time of output may be changed from other parts so that the correction can be easily understood.

If the relationship between the devices is specified by the role specifying means 15, a line may be connected between the devices based on the information of the role and the connection information based on the role stored in advance. In the embodiment, the wiring diagram creating means 16 for automatically creating the wiring diagram from the information of the specified type, position, and role of the device is provided.

After creating the wiring diagram, it is preferable that the box can be automatically selected by using the box selection means 21 according to the type and number of the specified devices. Further, it is preferable that the estimation means 22 is used to automatically estimate, or these results can be output to the requester.

Up to this point, the explanation has been made with reference to the drawings of the high-voltage power receiving equipment, but as can be understood from FIGS. 17 and 18, the drawing system 1 is used to create the drawings for the distribution board and the distribution board. can do. In the diagram provided by the requester shown in FIG. 17, since a plurality of breaker symbols exist on the same x value and one breaker symbol does not exist on the same x value, the breaker symbols do not exist on the same x value. A breaker symbol having a y value larger than that of a plurality of breaker symbols on the same x value is determined to be the main breaker 81. Further, the symbol of the breaker having a smaller y value than the symbol determined to be the main breaker 81 is determined to be the branch breaker 82. Further, the symbol of the breaker having a larger y value than the symbol determined to be the main breaker 81 is determined to be the main primary side breaker 83. As a result, the drawing system 1 draws a diagram as shown in FIG.

Further, as can be understood from FIGS. 19 and 20, the drawing system 1 can be used for creating a drawing for the control panel. In the diagram provided by the requester shown in FIG. 19, since a plurality of breaker symbols exist on the same y value, the breaker symbol having the smallest x value is determined to be the main breaker 81. Further, the symbol of the breaker having a larger x value than the symbol determined to be the main breaker 81 is determined to be the branch breaker 82. Further, it is determined that the symbol existing on the same x value as the symbol determined to be the branch breaker 82 is the symbol of the device 85 attached to the branch breaker 82. As a result, the drawing system 1 draws a diagram as shown in FIG. 20.

Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be in various modes. For example, the x value and the y value are not set to one specific value, and a width can be provided within a range where there is no problem.

The illustrated flows may be reordered, deleted or modified, or include other steps, as long as they are in line with the object of the present invention.
