BACKGROUND OF THE INVENTION
The present invention relates to a plant management apparatus, and more particularly to a plant management apparatus that manages a piping configuration for transporting materials such as petroleum to a predetermined facility in a plant such as petroleum off-site.
[0002]
[Prior art]
In general, in a plant such as oil off-site, a large number of pipes are arranged in a network in order to transport supplies such as oil stored in tanks to a predetermined point such as a tanker.
Therefore, it is necessary to efficiently select a piping path that connects the material source, that is, the FROM facility, to the material destination, that is, the TO facility.
[0003]
Conventionally, in such a management apparatus for managing the piping of a plant, an auto lineup function for automatically selecting a predetermined piping route based on a connection form and connection information between facilities inputted in advance is used. ing.
In this case, an image corresponding to each facility or pipe is arbitrarily arranged as a part on the screen, and a path screen showing a connection form between the facilities is generated.
Further, actual data indicating these connection forms, that is, connection information indicating which piping is connected between which facilities, is operated and input separately from the pass screen.
[0004]
[Problems to be solved by the invention]
However, in such a conventional plant management apparatus, it is desired that the operator inputs the connection information of the pipes connecting the facilities from the keyboard, which increases the operation burden on the operator and causes an input error. There was a problem that it took time to create information for auto lineup.
In addition, there has been proposed an apparatus in which connection information is automatically created from an image image generated on a pass screen (see, for example, JP-A-4-302800).
[0005]
In this case, since the connection information is created from the position of the image image arranged on the path screen, the processing load on the apparatus is heavy, and in this case also it takes time to create information for auto lineup. There was a problem.
This invention is for solving such a subject, and it aims at providing the plant management apparatus which can create the information required for an auto lineup in a short time, which can reduce the operation burden to an operator significantly. Yes.

In addition, each object has position information in which objects of other parts connected to the corresponding parts are stored as logical connection information.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of a plant management apparatus according to an embodiment of the present invention.
In the figure, 1 sets the connection form of various facilities and piping used in the plant based on an instruction from the data input unit 1A, and generates lineup information indicating a piping route connecting predetermined facilities based on the connection form. A configuration device.
[0011]
In the configuration apparatus 1, 11 is a screen that edits the connection relationship between each equipment by arranging image images corresponding to various equipment and piping used in the plant as parts on the screen, and logically connects the parts. It is a path screen editing unit that creates object information 12 including connection information.
Reference numeral 14 denotes a connection information creation unit that creates connection information 15 indicating the correspondence between piping and facilities connected to both ends of each piping from the object information 12.
[0012]
Also, 16 is a line-up information creating unit that extracts a piping path connecting predetermined facilities based on the connection information 15 and creates line-up information 17 indicating the piping path, and 18 is an arbitrary line based on the line-up information 17. It is a line-up display unit that highlights the piping route on the screen of the data display unit 1B.
[0013]
Next, the operation of the present invention will be described with reference to FIG.
FIG. 2 is a flowchart showing a schematic process in the configuration apparatus, and particularly shows a processing procedure until connection information is created.
In the path screen editing unit 11, various equipment and piping connection forms used in a predetermined equipment range in the plant are edited using a predetermined editing tool based on an instruction from the data input unit 1 </ b> A.
[0014]
FIG. 3 is an explanatory view showing a screen output example of the path screen editing unit.
An image image, that is, a part indicating any equipment or piping from the tool box 11B, is selected by the mouse, and is arranged on the sheet screen 11A in the center of the screen.
In response to this, an information management unit, that is, an object indicating various attributes relating to the part is generated (step 31).
[0015]
Each facility part such as a tank, a pump, a valve, or a flow meter is provided with a connection point, that is, a port, with a piping part indicating piping.
Here, when the equipment part or the piping part is placed or moved, if the port of the equipment part and the end point of the piping part are present at the same position on the sheet screen 11A, the equipment part and the piping part are logical. Is determined to be connected.
[0016]
Then, the logical connection relationship between the two is stored as logical connection information in the equipment part and piping part objects, and the object is updated (step 32).
In this way, by arranging various parts on the sheet screen, the objects of each part are repeatedly generated and updated, and various equipment and piping connection forms are output as object information 12 composed of these objects.
[0017]
Thereafter, according to the end of editing (step 33: YES), the connection status between the parts is checked based on the object information 12 (step 34). If the connection status is incorrect (step 35: NO), Returning to step 31, the error is corrected and edited.
If there is no error and it is normal (step 35: YES), connection information is automatically generated based on the object information 12 (step 36), and the series of processing ends.
[0018]
Next, the configuration of the object information will be described with reference to FIG.
FIG. 4 is an explanatory diagram showing an example of the configuration of object information, where (a) shows an example of connection form, (b) shows a parts list, and (c) shows an object group.
As shown in FIG. 4 (a), the valve (VALVE1) and the pump (PUMP1) are provided with ports (P1, P2) as connection points for connecting the pipe (PIPE1). Connected.
[0019]
The object information 12 includes a parts list 13 of each part constituting the connection form, and an object group of these parts, that is, objects 12A to 12C.
The parts list 13 is a list of storage positions, that is, pointer addresses of the objects 12A to 12C of each part in the object information 12, as shown in FIG.
[0020]
In this example, the pointers of the objects included in the object group shown in FIG. 4C, that is, the pointer a10 of the valve object 12A, the pointer a20 of the piping object 12B, and the pointer a30 of the pump object are stored. .
Thereby, the object of each part which comprises a connection form can be referred easily in the object information 12. FIG.
[0021]
FIG. 5 is an explanatory diagram showing a configuration example of an object of each part.
As shown in FIG. 5, each of the objects 12A to 12C is composed of a plurality of subordinate objects that indicate their attributes hierarchically.
For example, the piping object 12B is composed only of link objects indicating attributes of the entire part.
[0022]
On the other hand, the valve object 12A and the pump object 12C include a part object indicating an attribute of the entire part, a parameter object indicating an attribute of the connection point of the part, and a physical connection point of the part, that is, an attribute of the port. It consists of the port object shown.
In particular, in the objects 12A and 12C, a hierarchical connection relationship is configured in the order of the parameter object and the port object with the part object as the highest level.
[0023]
These part object, parameter object, and port object mutually have logical connection information between hierarchically adjacent objects.
In particular, the port object mutually has logical connection information with a link object included in object data of adjacent parts, that is, pipes.
[0024]
As the logical connection information of these objects, there is a mutual object storage position, that is, a pointer address in the object information 12, and the objects connected to each other are referred to using these pointer addresses. The attributes of these objects are roughly classified into attributes necessary for drawing the part on the path screen, that is, a picture part object, and actual functional attributes of the part, that is, a function part object.
[0025]
In particular, when using the attribute information of each object, the attributes of the picture part object are mainly referred to when drawing the pass screen, and the attributes of the function part object are mainly referred to when creating the connection information. .
Therefore, each object has logical connection information between a picture part object and a functional part object in the same object, and for other adjacent objects, between picture part objects and functional part objects Each of them has logical connection information separately.
[0026]
For example, as shown in FIG. 5, in the port object P2 in the object 12A of the valve VALVE1, the picture part object and the functional part object respectively have logical connection information composed of pointer addresses of each other.
The picture object of the port object P2 has logical connection information including pointer addresses to the picture object of the parameter object P2 in the same object 12A. The functional object of the port object P2 is also the parameter object. It has logical connection information consisting of a pointer address to the P2 function part object.
[0027]
Further, the picture part object of the port object P2 in the object 12A of the valve VALVE1 has logical connection information including pointer addresses to the picture part objects of the link objects in the adjacent pipe object 12C, and the port object P2 Similarly, the functional unit object has logical connection information including a pointer address to the functional unit object of the link object.
[0028]
6 is an explanatory view showing an object of the valve VALVE1, FIG. 7 is an explanatory view showing an object of the pipe PIPE1, and FIG. 8 is an explanatory view showing an object of the pump PUMP1, and includes parts, parameters P1, ports P1, parameters P2, and ports. A picture part object and a functional part object are provided for each of the P2 and link objects.
Each object is provided with a pointer group as one piece of attribute information, in which an address pointer indicating logical connection information is stored.
[0029]
Therefore, for example, in the pointer group of the picture part object of the port P2 in the valve VALVE1 (see FIG. 6), the pointer address b14 of the functional part object and the pointer address a13 of the picture part object of the parameter P2 are stored.
Furthermore, the pointer address a20 of the link picture part object in the pipe PIPE1 is stored.
[0030]
Note that attribute information such as drawing position coordinates on the path screen is stored in the picture object of the part object and the link object. In addition, in the function object of the part object and the link object, attribute information such as a name (ID) for identifying each part and a classification indicating the type of the part is stored.
[0031]
In particular, for information such as a pump and a flow meter in which the direction in which the material flows is specified, attribute information called a flow path indicating the flow direction is stored.
In addition, as for the configuration of the object of each part and the configuration of each object constituting the object, a template is prepared in advance according to the type of the part and the type of the object, and the actual equipment ( The specific attribute information is stored according to the part or object.
[0032]
Next, the connection information creation process will be described with reference to FIG.
FIG. 9 is a flowchart showing a connection information creation procedure, where (a) shows connection information creation processing and (b) shows parts information storage processing.
After the connection status of the object information described above is confirmed, the connection information creation unit 14 executes connection information creation processing shown in FIG. 9 to automatically create connection information based on the object information.
[0033]
FIG. 10 is an explanatory diagram showing a configuration example of connection information.
The connection information 15 (see FIG. 1) is information indicating the correspondence between the pipes and the equipment connected to both ends of each pipe, and includes item information as shown in FIG.
The connection ID is a name uniquely assigned to each pipe, and the pipe is identified by this.
[0034]
The FROM name and the TO name are the names of the equipment (parts) connected to each end of the pipe. Here, they are expressed as FROM and TO for convenience, but they coincide with the flow direction of goods. Absent.
The FROM facility classification and the TO facility classification are classification names indicating the types of facilities indicated in the FROM name and the TO name.
[0035]
Further, the FROM channel and the TO channel are values indicating the flow direction of the materials included in the facilities indicated by the FROM name and the TO name.
For example, pumps, flow meters, valves, and the like may have a flow direction that is unique to each facility. In such a case, the port to which the pipe is connected is connected upstream or downstream of the facility. Side or other (both directions) is shown.
[0036]
When creating such connection information, as shown in FIG. 9A, first, when there is an unprocessed part in the object information (step 51: YES), one of the unprocessed parts is selected. (Step 52).
Then, the pointer of the picture part object of the part is read from the parts list 13 (step 53), and the pointer of the functional part object is read from the pointer group of the picture part object (step 54).
[0037]
Next, a classification indicating the type of the part is acquired from the attribute information of the functional unit object (step 54), and it is determined whether or not the classification indicates “pipe” (step 55).
If the selected part classification is not piping (step 55: NO), the process returns to step 51 to select the next unprocessed part.
[0038]
On the other hand, when the selected part classification is piping (step 55: YES), the name indicating the ID of the part is acquired from the attribute information of the functional unit object and stored in the connection ID of the connection information. (Step 56).
In the same manner, a part information storage process for acquiring a pointer indicating an object of a part connected to one and the other end points from the pointer group, acquiring information on the part based on the pointer, and storing the information in the connection information is a subroutine. (Steps 57 and 58).
[0039]
In the part information storage process shown in FIG. 9B, first, the pointers of the objects connected to the upper layer side are sequentially obtained from the pointer group of the functional unit object pointed to by the obtained pointer (step 61). The upper level object, that is, the part object is reached, the name and classification of the part are obtained from the functional unit object, and stored in the FROM name (or TO name) and FROM classification (or TO classification) of the connection information (step 62). ).
[0040]
Further, if necessary, the flow path of the part is acquired from the functional unit object, and stored in the FROM flow path (or TO flow path) of the connection information (step 63), and the subroutine processing is terminated.
Thus, after acquiring the information of each part connected to both ends of the pipe and storing it in the connection information, the process returns to step 51 and repeats steps 52 to 58 until there are no unprocessed parts. When there is no more (step 51: NO), the series of processing ends.
[0041]
Therefore, for example, in the case of the connection form shown in FIG. 4A, for the pipe PIPE1, the pointer a20 indicating the picture part object of the link object of the pipe PIPE1 is first referenced from the parts list 13 shown in FIG. As shown in FIG. 7, the pointer b20 of the functional unit object is referred to from the pointer group of the picture unit object.
Then, the pointer b14 of the port P2 of the valve VALVE1 connected to one end point thereof is referred from the pointer group of the functional unit object.
[0042]
Next, as shown in FIG. 6, the function unit object of the port P2 pointed to by the pointer is selected, and the pointer b13 of the parameter P2 connected to the upper side is referred to from the pointer group.
Similarly, the pointer b10 of the part connected to the upper side is referred from the pointer group, and the functional unit object of the part connected to the highest level is searched in this way, and the attribute information is connected. Stored as information.
[0043]
In this way, the path screen editing unit 11 edits the path screen that displays the connection form between each equipment by arranging parts indicating each equipment and piping on the screen according to a predetermined operation, and the logic between each part. The object information 12 including the general connection information is created, and the connection information creating unit 14 creates the connection information 15 indicating the correspondence between each pipe and the equipment connected to each pipe based on the object information 12. Since it is created automatically, the burden on the operator can be greatly reduced, and the information necessary for auto lineup can be created in a short time.
[0044]
In addition, the connection information creation unit 14 extracts the parts connected to both ends of the pipe by searching the logical connection information among the objects of each part included in the object information 12, and extracts the parts from the extracted part objects. Since connection information is automatically created by acquiring information about equipment corresponding to the part, connection information can be created by a relatively simple search.
[0045]
In addition, each object is provided with position information in which objects of other parts connected to the corresponding part are stored as logical connection information, and an object of a desired part is searched based on these position information. As a result, it is possible to search for an object of a desired part at a very high speed with simple information.
[0046]
Further, by using such connection information 15 as well as the path screen showing the connection form, that is, the drawing information, the consistency of the connection form edited by the path screen editing unit 11 can be checked easily and accurately.
FIG. 11 is an explanatory diagram showing the consistency check of the connection form.
For example, when the same equipment, here, valve B is connected on different seat screens as shown in FIGS. 11A and 11B, other parts connected before and after valve B based on connection information 15 It can be easily found that there is a contradiction in (valves A and B), and it can be determined that there is an error in consistency.
[0047]
In addition, since the connection information 15 includes the flow direction of goods, as shown in FIG. 11 (c), in the connection form in which the flow flows from the valves A, B, and C toward the branch point, it can be performed in any direction. It can be easily found that there is no output port of goods, and it can be judged that there is an error in consistency.
Further, as shown in FIGS. 11D and 11F, the flow direction of resources can be automatically specified by the arrangement direction of parts such as the pump PUMP1 on the path screen, and the auto lineup can be performed more quickly.
[0048]
In particular, since the flow direction of such goods is extracted from the object information 12 and automatically stored in the connection information 15, it is not necessary for the operator to separately input as in the conventional case, and input mistakes can be suppressed. At the same time, work efficiency can be improved.
[0049]
【The invention's effect】
As described above, according to the present invention, parts indicating each facility and piping are arranged on the screen in accordance with a predetermined operation to display a connection form between each facility and a path including logical connection information between each part. In addition to creating a screen, connection information indicating the correspondence between each pipe and the equipment connected to each pipe and the flow direction of goods in each pipe is automatically created, which reduces the operational burden on the operator. The information required for auto lineup can be created in a short time.
