The drawing target information input unit 11 can acquire these pieces of information input by the user as information necessary for creating a sequence diagram, and input them to the drawing data search unit 12 . Note that the location number may include the panel number of the digital control panel, which is the object to be drawn, the device number, and the like.

The drawing data search unit 12 uses information such as the system number and the location number input by the drawing object information input unit 11 to search the drawing data stored in advance in the drawing data storage unit 13 to find information related to the object to be drawn. Drawing data (hereinafter referred to as "target drawing data") is searched. The drawing data storage unit 13 stores interlock block diagrams (IBD), outline drawings, instrument specifications (IDS), Data of design drawings (upstream documents) including equipment design specifications and the like are stored in association with system numbers and location numbers of the products. The IBD and outline drawing are each represented by CAD data, for example, and the IDS and equipment design specifications are each represented by character-coded text, for example. Based on the information input by the drawing target information input unit 11, the drawing data search unit 12 searches for a set of data of design drawings (upstream documents) of the object to be drawn as target drawing data.

The symbol extraction unit 14 extracts symbols related to input/output signals of the object to be drawn and character information associated with the symbols from the IBD included in the target drawing data searched by the drawing data search unit 12 . Generally, in the IBD of the digital control panel, an input signal to the digital control panel and an output signal from the digital control panel are represented by signs or figures (symbols) having a predetermined shape. The symbol extracting unit 14 extracts a portion drawn in a predetermined shape in the IBD of the object drawing data as a symbol, and reads the character information written around the symbol, thereby extracting the input/output signal of the object to be drawn.

In general, the IBD of the digital control panel used in the plant includes input/output signals for measurement and control related to plant monitoring and operation, but input/output signals derived from the digital control panel is not listed. This corresponds to, for example, an operation control signal for a cooling fan in a control panel. The signal extraction unit 16 can extract the input/output signal by recognizing the portion related to the input/output signal in the outline drawing of the target drawing data. The shape of the portion to be recognized in the outline drawing by the signal extraction unit 16 is stored in advance in the extraction target shape storage unit 17 .

The information addition unit 18 adds signal information regarding specifications of input/output signals represented by the symbol to the symbol extracted from the IBD of the target drawing data by the symbol extraction unit 14 . At this time, the information adding unit 18 uses, for example, character information read from the vicinity of the symbol extracted by the symbol extracting unit 14 as a search key to obtain signal information (signal type , design range, instrument type, installation location, etc.) are obtained by searching from the IDS included in the target drawing data.

These functional blocks are implemented in the drawing system 1 by, for example, the processor 2 in FIG. 1 executing a predetermined program or application stored in the storage 4 .

The existing drawing information input unit 31 acquires information necessary for searching upstream books corresponding to existing sequence diagrams, and inputs the information to the drawing data search unit 12 . For example, the existing drawing information input unit 31 acquires information such as system numbers and location numbers for products for which sequence diagrams have already been created manually or by the drawing system 1 in the same way as the drawing target information input unit 11. can be done.

When the information acquired by the existing drawing information input unit 31 is input to the drawing data search unit 12, the drawing data search unit 12, the symbol extraction unit 14, the signal extraction unit 16, the information addition unit 18, and the list creation unit 19: Processing similar to that described in the first embodiment is performed respectively. As a result, the list creating unit 19 creates a list of input/output signals represented in the upstream document corresponding to the existing sequence diagram. This list is input from the list creation section 19 to the list comparison section 34 .

The existing sequence diagram input unit 32 acquires an existing sequence diagram related to the product whose information is acquired by the existing diagram information input unit 31 and inputs it to the list conversion unit 33 .

As in the first embodiment, the drawing system 1 of the present embodiment can also create a new sequence diagram of the object to be drawn by operating according to the flowchart of FIG. Description is omitted.

Step S301: The existing sequence diagram input unit 32 acquires an existing sequence diagram.

Step S302: The list conversion unit 33 creates an input/output signal list from the existing sequence diagram acquired in step S301.

As described in the first embodiment, if the selected signal is, for example, a signal derived from the digital control panel, it is determined that the signal is not described in the IBD, and the process proceeds to step S309. On the other hand, if the signal does not correspond to these signals, it is determined that the signal is described in the IBD, and the process proceeds to step S312.

Step S309: The difference extraction unit 35 extracts the portion corresponding to the signal selected in step S307 from the outline drawing included in the upstream document acquired in step S303. Here, the portion to be extracted from the outline drawing can be determined based on the input operation performed by the user using the input/output device 6, for example. Alternatively, the drawing system 1 may automatically determine the portion to be extracted from the outline drawing using a predetermined image recognition process or the like.

Step S312: The difference extraction unit 35 extracts the symbol corresponding to the signal selected in step S307 from the IBD included in the upstream book acquired in step S303. Here, for example, by searching the IBD for character information describing the name of the signal and identifying the symbol corresponding to the character information, the symbol to be extracted from the IBD can be determined. Alternatively, the symbols to be extracted from the IBD may be determined based on the input operation performed by the user using the input/output device 6 .

Step S313: The difference learning unit 36 learns the signal pattern of the symbols extracted from the IBD in step S312. Here, for example, the signal pattern can be learned by associating the symbol with the signal selected in step S307.

Step S314: The learning result of step S313 is output from the difference learning unit 36 to the extraction target symbol storage unit 15, and the extraction target symbol storage unit 15 stores the learning result. As a result, the learning result for the signal selected in step S307 is reflected in the symbol extraction unit 14. FIG. After executing the process of step S314, the process proceeds to step S315.

Step S315: It is determined whether or not all signals having a difference have been selected in step S307. If there is an unselected input/output signal determined to have a difference in step S306, the process returns to step S307, and after selecting one of them in step S307, steps S308 to S315 are repeated. On the other hand, if all the input/output signals determined to have a difference in step S306 have been selected in step S307, the process shown in the flowchart of FIG. 7 ends.
