[0011]
FIG. 3 is a flowchart showing a processing flow of graphic processing technology (facility input processing) in the facility management system according to the embodiment of the present invention. The description will be continued with reference to FIGS. In the facility management system according to the present embodiment, it is assumed that the shape of a figure is determined for each facility type. Examples of the shape of the figure include a broken line, a rectangular surface, and a symbol. For each equipment type, an attribute item set in advance can be displayed on the map as a character string (attribute character string).
[0012]
First, in step 301, the user designates the equipment type to be input. At this time, the figure shape to be displayed is determined based on the designated equipment type. In step 302, a position for displaying a graphic is designated. In step 303, an attribute value is designated. In step 304, a layer to be drawn is acquired. Details of this processing will be described later with reference to FIGS. In step 305, the size of the character string of the attribute item to be displayed is acquired. Details of this processing will be described later with reference to FIG. In step 306, it is checked whether the figure shape of the facility is a symbol. If it is not a symbol, graphic data is displayed and registered in the attribute data table 11 in step 309, and the process ends. On the other hand, when the figure shape of the facility is a symbol, the facility symbol is acquired in step 307. Details of this processing will be described later with reference to FIG. In step 308, the symbol size is obtained. Details of this processing will be described later with reference to FIG. In step 309, graphic data display processing and data registration processing in the attribute data table 11 shown in FIG. 1 are performed, and the series of processing ends.
[0013]
FIG. 4 is a diagram showing an example in which the details of the specific facility input processing shown in FIGS. 1 to 3 are displayed on a map. The equipment type of the symbol shape is selected, and the graphic position P1 is designated on the displayed map (step 303 in FIG. 3). When the attribute data is input (steps 304 to 308 in FIG. 3), the equipment figure C1 and the attribute character string S1 are arranged (displayed) on the map (step 309 in FIG. 3). In the figure, the figure position P1 is indicated at the time of input, and the equipment C1 (valve graphic) and the display character string S1 (valve) are displayed after the input.
[0014]
Next, with reference to FIG. 5 and FIGS. 6 to 8, the details of the flow of the graphic information acquisition process in the facility management system according to the embodiment of the present invention will be described. FIG. 5 is a flowchart showing the flow of the graphic information acquisition process, and corresponds to the layer acquisition process 304 of FIG. 6 to 8 show examples of table data at that time. In addition to the layer acquisition process (step 304) shown in FIG. 3, the graphic information acquisition process shown in FIG. 5 includes a character size acquisition process (step 305), an equipment symbol acquisition process (step 307), and a symbol size acquisition process (step 307). The process is the same as that in step 308).
[0015]
By the start of the processing in FIG. 6 (A), the user has a graphic information table with unique definition values for each graphic information type, equipment type, and attribute value combination, and a graphic information type, equipment type, and attribute item combination. Is created as a parameter data table. The user may customize using an existing database. In addition, an attribute data table in which attribute items 1 to n are input is created for each shape element ID.
[0016]
First, in step 501, for example, when the user inputs “valve” as the equipment type and “layer” as the graphic information type, the equipment management program 6 (FIG. 1) displays the parameters as shown in FIG. Get parameter data by referring to the table. If search data exists in the parameter table, “attribute item 2 attribute item 3” is acquired as parameter data of the corresponding attribute item combination from the parameter data table.
[0017]
The processing from step 502 to step 505 is processing for sequentially processing the set attributes 1 to n. When the process item corresponds to the attribute item combination of the parameter data, the parameter data is converted as the attribute value of the attribute item. The converted data is secured in the program as a “conversion value”.
[0018]
In step 502, it is checked whether or not all attribute items have been processed. If it is determined in step 502 that all attribute items have been processed, graphic information cannot be acquired, so an error is returned (step 507), and the process returns to the caller process. In step 502, if an unprocessed portion of the attribute item processing remains, the following processing is performed. First, parameter conversion is performed for attribute item 1 (step 503). If converted, a definition value of graphic information is acquired based on the converted parameter (step 504). Next, it is checked whether or not the graphic information has been acquired (step 505). If it can be obtained, the graphic information is returned (step 506), and the process returns to the calling process. If the graphic information cannot be acquired in step 505, the process proceeds to step 502, and the process is continued for the next attribute item.
[0019]
Referring to FIG. 7C, attribute item 1 is a processing target here, but no conversion is performed because there is no target item in the attribute item combination of parameter data (a conversion value cannot be obtained). ). Referring to FIG. 7D, when the graphic information table is searched based on the condition that the equipment object is “valve”, the graphic information type is “layer”, and the conversion value is “(none)”, the corresponding data is found. Since it cannot be found, it is assumed that there is no target data.
[0020]
Next, the process returns to step 502, and attribute item 2 is set as a processing target. Since attribute item 2 is a conversion target from “attribute item 2 attribute item 3” acquired in FIG. 6B, the attribute value “low pressure” of attribute item 2 is acquired from the attribute data table and set as the conversion value. To do. That is, in step 503, the parameter data is converted. With reference to (E) of FIG. 8, when the parameter conversion is performed on the attribute item 2 to be processed, the conversion value “low pressure” can be acquired. Next, in step 504, a definition value of graphic information is acquired based on the converted parameters. Next, in step 505, it is checked whether or not graphic information has been acquired. Referring to FIG. 8F, the graphic information table is searched from the current conversion value. Since there is no data corresponding to the conversion value “low pressure” in the graphic information table, the processing returns to step 502 with no target data, and then attribute item 3 is processed.
[0021]
For attribute item 3, in step 503, the parameter data is converted. Referring to FIG. 9G, since the attribute item 3 is a conversion target from the parameter data “attribute item 2 attribute item 3” acquired in FIG. 6B, the attribute value “3” of the attribute item 3 is obtained from the attribute data. 50 ”is acquired and added after the already stored“ low pressure ”in the same manner as the attribute item combination, and set as a conversion value. That is, when the parameter data is converted for the attribute item 3 to be processed, the conversion value “low pressure aperture 50” can be acquired. Next, in step 504, a definition value of graphic information is acquired based on the converted parameter. Next, in step 505, it is checked whether graphic information has been acquired. Referring to FIG. 9H, when the graphic information table is searched based on the condition that the equipment type is “valve”, the graphic information type is “layer”, and the conversion value (= attribute value combination) is “low pressure aperture 50”. There is corresponding data, and “301” can be acquired as the definition value.
[0022]
If the graphic information can be acquired, the graphic information definition value “301” is returned in step 506, and the process returns to the caller process in FIG. Through the above processing, the graphic information type “layer”, the equipment type “valve”, the attribute value combination “low pressure aperture 50”, and the definition value “301” are searched, and based on this, graphic display and registration of attribute data (FIG. 3). Step 309) can be performed.
[0023]
In the above example, the parameter data table is searched from the condition that the equipment type is “valve” and the graphic information type is “layer”, and the attribute value combination is a combination of the attribute item 2 “low pressure” and the attribute item 3 “caliber” And using this as a search key, the definition value 301 is obtained from the graphic information table. By changing the definition value of the graphic information table, or by changing the attribute value combination in the parameter data table, the user can It can be easily customized. For example, in the acquisition of graphic information, when a combination of multiple attribute items is targeted, it is not necessary to convert all the attribute items to attribute values, and the graphic information definition values corresponding to the values generated during the conversion are set. You can also
[0024]
Next, an example of obtaining the character size (step 305 in FIG. 3) will be described with reference to FIG. As shown in FIG. 10A, the graphic information type of the graphic information table is “character size” in the sample data at the start of processing, and the definition value is also a value different from FIG. “1000” and “1200”.
[0025]
As shown in FIG. 10B, the equipment type is “valve”, the graphic information type is “character size”, and the conversion value, that is, the attribute, is the same as the method described in FIGS. When the graphic information table is searched based on the condition that the value combination is “low pressure”, it can be seen that the corresponding data exists in the graphic information table. Based on this search result, “1000” can be acquired as the definition value.
[0026]
Next, an example of equipment symbol acquisition (step 307 in FIG. 3) will be described with reference to FIG. As shown in FIG. 11A, in the sample data at the start of processing, the graphic information type of the graphic information table is “equipment symbol”, and accordingly, the definition value is also a value different from that in FIG. “L_VALVE” and “M_VALVE”.
[0027]
As shown in FIG. 11B, as in the method described with reference to FIGS. 6 to 9, the equipment type is “valve”, the graphic information type is “equipment symbol”, and the conversion value, that is, the attribute When the graphic information table is searched based on the condition that the value combination is “low pressure”, it can be seen that the corresponding data exists in the graphic information table. Based on the search result, “L_VALVE” can be acquired as the definition value.
[0028]
Next, an example of obtaining a symbol size (step 308 in FIG. 3) will be described with reference to FIG. As shown in FIG. 12A, the graphic information type of the graphic information table is “symbol size” in the sample data at the start of processing, and the definition value is also a value different from that in FIG. “500” and “750”.
[0029]
