Description

  The present invention relates to a three-dimensional CAD (Computer Aided Design) system that automatically associates an electrical circuit diagram and a device mounting diagram in designing a control panel or the like.

  Conventionally, in the design of control panels, etc., the electrical circuit diagram created by electrical circuit design is designed using electrical CAD, and the design of how electrical components are arranged on the control panel, etc. based on the electrical circuit diagram. However, a mechanical drawing describing the configuration, arrangement, and the like has been created by three-dimensional CAD. For this reason, it is necessary to refer to both the electrical circuit diagram and the mechanical drawing for work such as actual control panel manufacture, inspection, maintenance and repair after operation.

  In a control system in a large-scale plant such as a power plant, various electrical components are installed in one product. Therefore, check where an arbitrary electrical component on the electrical schematic is installed in the product. Was very difficult. In addition, since a large number of devices such as control panels equipped with various electrical components are arranged, it is possible to easily identify any electrical component, in addition to design and manufacturing work, for maintenance work after operation, etc. It was a very important requirement for improving work efficiency. Therefore, conventionally, as a method of determining the position of an electrical component attached to a product such as a control panel, an identification number (hereinafter, referred to as a physical position in the product) for each electrical component of the electrical circuit diagram. (Referred to as logical coordinates) on the electric circuit diagram. Logical coordinates are the position of the board in the control panel, for example, a symbol indicating the number of steps from the top, and the specific position on the board as the origin, and the vertical and horizontal positions are separated by a specific distance, and the vertical and horizontal positions This is defined in combination with a symbol representing. For example, when the number of stages of the substrate is A, B, C, D, the position on the substrate is divided into A, B, C, D in the vertical direction and 1, 2, 3, 4 in the horizontal direction, Arrangement positions of individual electrical components can be represented by symbols such as “FA1” and “FB2”.

  As a result, a maintenance worker who maintains the control system can identify the position of the component attached in the apparatus by looking at the logical coordinates on the electric circuit diagram. On the other hand, in the control system design process, an electrical component layout is created from the three-dimensional CAD data of the mechanical drawing, the electrical component on the electrical circuit diagram is placed on the layout diagram, and created from the position on the layout diagram. By assigning the logical coordinates to the electric parts of the electric circuit diagram, the association between the electric circuit diagram and the electric parts described in the mechanical drawing can be understood.

Patent Document 1 automatically generates a three-dimensional model based on design information designed by another CAD system, such as a mechanical CAD for mechanical design, an electrical CAD for electrical design, and an optical CAD for optical design. There is a disclosure about an example of a three-dimensional CAD system that can be designed while performing an operation simulation linked with design information by the CAD system.

  In this way, the layout drawing that has been created in the past associates the electrical CAD for the electrical circuit design with the design information for the three-dimensional CAD for the structural design. The transcription of the logical coordinates to the electrical circuit diagram was manually performed by the designer. For this reason, there is a problem that a lot of time is required for the work, and errors in allocation of logical coordinates and a transcription work occur, resulting in low reliability and design productivity.

  In the example shown in Patent Document 1, it is possible to generate a three-dimensional model using design information by another CAD system. For example, an electric component of an electric circuit diagram and a corresponding electric component of the three-dimensional model There is no function to correlate each other and provide it to the user. For this reason, it has been impossible to provide materials such as drawings in which design information by the plurality of CAD systems is associated with each other in a form that can be used by the user.

  The present invention has been made in view of the above points. For example, information on an electric circuit diagram designed by an electric CAD and information on a mechanical drawing designed by a three-dimensional CAD are associated with each other, and mounting positions of individual electric components are obtained. An object of the present invention is to provide a three-dimensional CAD system capable of easily recognizing an image.

The present invention provides a three-dimensional CAD operation unit that generates and manages three-dimensional CAD data, a three-dimensional data storage unit that stores data generated by the three-dimensional CAD operation unit, and generates and manages electric CAD data. Reads the electric CAD calculation unit, the electric circuit data storage unit that stores the data generated by the electric CAD calculation unit, the data generated by the three-dimensional CAD calculation unit and the data generated by the electric CAD calculation unit, And a data link processing unit for associating the data with each other, when displaying a 3D model drawing based on the 3D CAD information stored in the 3D data storage unit, by attaching the information of the electrical components of the drawing on a display screen of a three-dimensional model drawings by the information of the three-dimensional CAD 3D model When displaying an electrical circuit drawing stored by the electrical circuit data storage unit, the logical coordinate information of the 3D model drawing based on the 3D CAD information associated by the data link processing unit is displayed. The information is pasted on the display screen of the electric circuit drawing based on the information of the above and displayed simultaneously with the electric circuit drawing.
In this case, the data link processing unit automatically assigns the logical coordinates indicating the mounting position in the product for the electric parts of the three-dimensional CAD data generated by the three-dimensional CAD calculation unit, and the assigned logical coordinates are converted into the electric CAD. It outputs to a calculating part and registers as the attribute information of the said electrical component of electrical CAD data.
Alternatively, the data link processing unit outputs the electrical component attribute information to the three-dimensional CAD computation unit for the electrical component of the electrical CAD data generated by the electrical CAD computation unit, and outputs the attribute information of the electrical component of the three-dimensional CAD data. Register as

  In addition, the present invention creates a production drawing of a product manufactured by attaching an electrical component based on the 3D CAD data generated by the 3D CAD operation unit and the attribute information of the electrical component registered by the data link processing unit. A production drawing creation processing unit is provided.

  According to the present invention, it is possible to associate three-dimensional CAD data and electrical CAD data with each other and automatically register the automatically assigned attribute information in the three-dimensional CAD data and electrical CAD data. For this reason, work for associating data with each other, such as assignment of logical coordinates, which has been conventionally performed manually, can be performed in a short time, and productivity in design and manufacturing work is improved. Furthermore, since it is possible to easily refer to information on electrical parts corresponding to each other in the three-dimensional CAD data and the electrical CAD data, it is possible to improve work efficiency even in maintenance and inspection work after the start of operation of the control system. it can.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows a configuration example of a three-dimensional CAD system according to this example. In this example, a 3D CAD function for structural design is realized, and a 3D CAD server computer 1 incorporating a 3D CAD operation unit for generating and managing 3D CAD data is connected to the 3D CAD server computer 1. Connected to the 3D database 3 and 3D CAD server computer 1, which is a 3D data storage unit for storing design information such as 3D CAD data, via the network 13 to realize an electrical CAD function for designing electrical circuits. Electrical circuit data that stores electrical CAD data that is connected to the electrical CAD server computer 2 and electrical CAD server computer 2 that incorporates an electrical CAD calculation unit that generates and manages electrical CAD data and stores design information such as electrical circuit diagrams designed by electrical CAD Electric circuit database 4, three-dimensional CAD server computer 1, electric CAD server computer 2, and network as storage units 13 through the connecting constitutes a client computer 5 and 6 the three-dimensional CAD design and electrical CAD design.

  The client computer 5 is obtained by installing a program for realizing a three-dimensional CAD and an electric CAD function in a computer such as a personal computer (PC) having input / output devices such as a display device 7, a keyboard 9, and a mouse 11. is there. The client computer 6 has the same configuration. In FIG. 1, two client computers are connected, but two or more may be connected.

  The 3D database 3 includes product management information (3D) 31, electrical component identification information 32, electrical component mounting information 33 as information for associating with design information based on 3D CAD and electrical circuit design information based on electrical CAD. 3D model information 34 is stored. The electric circuit database 4 stores product management information (electricity) 41, circuit attribute information 42, and electric circuit information 43 as information on electric circuit design by electric CAD.

  Next, the configuration of the client computer according to this example will be described. Although there are a plurality of client computers, the configuration is the same, so the client computer 5 will be described as an example.

  FIG. 2 shows a configuration diagram illustrating a configuration example of the client computer. The client computer 5 is connected to the three-dimensional CAD server computer 1 and the electric CAD server computer 2 via a network. The client computer 5 receives data from the three-dimensional CAD processing unit 21 for designing the three-dimensional CAD, the electric CAD processing unit 22 for designing the electric CAD, the three-dimensional CAD server computer 1, and the electric CAD server computer 2. A data link processing unit 23 for reading and correlating each other, and a production drawing creation processing unit 24 for creating a production drawing of a product to be produced by attaching an electrical component based on the association data created by the three-dimensional CAD data and the data link processing unit 23 From the electric component display processing unit 25 that displays a screen for mutually confirming the correspondence between the three-dimensional CAD data and the electric component described in the electric circuit diagram, and the data storage unit 26 that stores data referred to by each processing unit Constitute. In the data storage unit 26, the three-dimensional data 27 read from the three-dimensional CAD server computer 1, the electric circuit data 29 read from the electric CAD server computer 2, and the association data 28 created by the data link processing unit 23 are registered.

  In this example, when performing the three-dimensional CAD design or the electric CAD design, the designer works using the client computers 5 and 6, and the three-dimensional database 3 or 3 via the three-dimensional CAD server computer 1 or the electric CAD server computer 2. Data stored in the electric circuit database 4 is read, displayed on the display devices 7 and 8 and edited, and the edited data is written into the three-dimensional database 3 or the electric circuit database 4.

  Further, according to this example, when performing the association work between the three-dimensional CAD data and the electric CAD data, the designer works using the client computers 5 and 6 and reads from the three-dimensional CAD server computer 1 and the electric CAD server computer 2. The logical coordinates are assigned based on the data, and the correlated data is stored in the three-dimensional database 3 or the electric circuit database 4 as attribute information. As a result, the three-dimensional CAD data and the electric parts registered in the electric CAD data can be associated one-to-one.

  Next, processing for associating three-dimensional CAD data with electrical CAD data using a client computer will be described. In this example, the association between the three-dimensional CAD data and the electric CAD data is performed by assigning logical coordinates to the electric parts on the electric circuit diagram on the electric CAD side, and by identifying the electric parts in the three-dimensional model of the three-dimensional CAD. By performing a process of assigning a certain instrument number, they can be associated with each other.

  FIG. 3 is a flowchart showing a processing example of logical coordinate / appliance number assignment processing by the data link processing unit 23. With reference to FIG. 3, the contents of the logical coordinate / appliance number assignment processing will be described. The left side of FIG. 3 shows processing performed from the data link processing unit 23 via the three-dimensional CAD processing unit 21, and the right side shows processing performed from the data link processing unit 23 via the electric CAD processing unit 22. In the following description, processing performed through the three-dimensional CAD processing unit 21 is referred to as “three-dimensional CAD”, and processing performed through the electric CAD processing unit 22 is referred to as “electric CAD”.

  First, in the three-dimensional CAD, a three-dimensional model reading process is performed (step S301). Here, for example, a product identification code is input by a user specifying a target product to be associated from a client, and in 3D CAD, product management information is based on the input product identification code. (3D) 31 is referred and a three-dimensional model is specified. Then, the information of the corresponding three-dimensional model is read from the three-dimensional CAD server computer 1 to the client computer. Next, an electrical component identification process is performed for identifying only electrical components from among the components of the read three-dimensional model (step S302). The part name of the component of the three-dimensional model is collated with the part name of the electric part identification information 32. If the part name corresponds to the electric part, the three-dimensional model name, hierarchy name, XYZ (three-dimensional model) are included in the electric part mounting information 33. Set the part name. Next, logical coordinate assignment processing is performed on the electrical component identified in step S302 (step S303). In the logical coordinate assignment process, logical coordinates expressing the mutual positional relationship of electrical components in the product are assigned from XYZ, which is a three-dimensional model space coordinate representing the mounting position of the electrical component, and set in the electrical component mounting information 33. . Next, the logical coordinates assigned in step S303 are displayed over the corresponding three-dimensional model (step S304). The user can confirm the logical coordinate allocation result on the screen displayed on the display device of the client computer.

  Next, the circuit attribute information 42 relating to the electric circuit diagram corresponding to the corresponding product identification code is requested to the electric CAD and read (step S305). On the electric CAD side, circuit attribute information 42 requested from the three-dimensional CAD side is output (step S311). Next, the component name of the electrical component mounting information 33 and the component name of the read circuit attribute information 42 are collated, and the appliance number of the circuit attribute information 42 is set in the electrical component mounting information 33 for the matching electrical component. A device number assignment process is performed (step S306). Note that when there are a plurality of identical part names when collating the part names, the assignment process is performed based on a preset assignment rule. The appliance number assignment rule will be described later. Next, the logical coordinates assigned in step S303 and the instrument number assigned in step S306 are displayed superimposed on the corresponding three-dimensional model (step S307). The user can confirm the assignment result of the logical coordinates and the instrument number on the screen displayed on the display device of the client. As a result of the confirmation, if it is determined that there is a change (step S308), the user changes the logical coordinates or changes the assigned position of the instrument number (step S309). The user can change the allocation of logical coordinates and instrument numbers by, for example, selecting the logical coordinates or instrument numbers displayed on the 3D model on the screen with the mouse and selecting arbitrary positions on the 3D model. Move to. After movement on the screen, the destination three-dimensional model name and hierarchy name are automatically recognized, and the change contents are set in the electrical component mounting information 33. When all the processes for changing the logical coordinates and appliance numbers that need to be changed have been completed and no change has been made in step S308, the assigned logical coordinates and appliance numbers are set in the circuit attribute information 42 and output to the electric CAD. (Step S310), the process ends.

  On the electric CAD side, the circuit attribute information 42 output from the three-dimensional CAD side is read (step S312). In the electric CAD, based on the read circuit attribute information 42, the assigned logical coordinates are superimposed and displayed as the attribute of the circuit of the electric part of the corresponding appliance number on the electric circuit diagram (step S313). The user can confirm the logical coordinate assignment result on the electric circuit diagram by the screen displayed on the display device of the client.

  The appliance number allocation rule in the appliance number allocation process in step S306 will be described. A rule for assigning the appliance number is set in advance in the data link processing unit 23 as assignment rule definition information. For example, as shown in FIG. 10, the allocation rule definition information 35 includes an allocation pattern 351 and an allocation condition 352. As the allocation condition 352, the user defines conditions such as “circuit classification” and “rating”, and the user can select an allocation rule by specifying arbitrary conditions before starting the logical coordinate and device number allocation processing. Keep it like that. For example, when the allocation pattern A “circuit classification” is selected, when there are a plurality of the same part names, the allocation processing is performed in the order of the highest voltage based on the circuit classification.

  14 to 17 show examples of screen display in the logical coordinate / appliance number assigning process according to this example. FIG. 14 is a display example of an electric circuit diagram of the electric CAD. The electrical circuit diagram 51 includes information such as the electrical component 52, the appliance number 53 of the electrical component (indicated as “YFY1” in the drawing), and the model 54 (indicated as “TSC-6J” in the drawing).

  FIG. 15 is a display example of a three-dimensional CAD three-dimensional model. In the logical coordinate / appliance number assigning process according to this example, only the electrical component is identified from the information of the three-dimensional model 61, and the logical coordinate is assigned to the identified electrical component. In the example of FIG. 15, logical coordinates are sequentially assigned in order from the upper left to the lower right, starting from the upper left of the front surface of the three-dimensional model. As a result, the logical coordinate 62 of “FY1” is assigned to the electrical component arranged at the upper left, and “FY2” and “FY3” are assigned in order downward.

  FIG. 16 shows an example in which the result of performing the device number assignment processing based on the circuit attribute information 42 read from the electric CAD system is displayed on the three-dimensional CAD three-dimensional model. In the example of FIG. 16, on the three-dimensional model 61, the assigned logical coordinates 62 (displayed as “FY1” in the figure), the instrument number 63 (displayed as “YFY1” in the figure), and the model 64 read from the circuit attribute information 42. (Displayed as “TSC-6J” in the figure). In this example, the user can check the logical coordinates and instrument numbers automatically assigned by the screen. Also, if you want to change the assignment, use this screen to change the assignment destination by selecting the display characters on the screen such as logical coordinates or instrument numbers you want to change with the mouse and moving to the location you want to change. Can do.

  FIG. 17 is an example in which the logical coordinates and instrument numbers determined to be assigned on the three-dimensional CAD three-dimensional model are read into the electric CAD system and displayed on the electric circuit diagram. In FIG. 17, in addition to the instrument number 53 (displayed as “YFY1” in the figure) initially displayed, the assigned logical coordinates 55 (displayed as “FY1” in the figure) can be displayed on the electrical circuit diagram 51. it can. In this example, the user can confirm the result of the logical coordinate and instrument number assignment processing on the electric circuit diagram on the screen.

  As described above, in this example, it is possible to automatically assign logical coordinates to the electric parts of the electric circuit diagram, and the time required for the work of assigning the logical coordinates to the electric circuit diagram that has been performed manually in the past is reduced. It can be greatly reduced and productivity can be improved.

  Next, the process of creating an electrical component assembly work instruction diagram by the production drawing creation processing unit 24 according to this example will be described. The electrical component assembly work instruction diagram is used to instruct the installation of electrical components necessary for product assembly based on a mechanical drawing designed by 3D CAD and a design drawing such as an electrical circuit diagram designed by electrical CAD. For example, a drawing of a three-dimensional model that is a mechanical drawing and an assembly component mounting list in which the contents of the electrical component mounting information 33 are in a list form are edited into one drawing.

  FIG. 4 is a flowchart showing a processing example of the electrical component assembly work instruction diagram creation processing by the production drawing creation processing unit 24. With reference to FIG. 4, the content of the electrical component assembly work instruction drawing creation process will be described.

  First, in the three-dimensional CAD, a three-dimensional model reading process is performed (step S401). Here, for example, the user specifies the product for which the electrical component assembly work instruction diagram is to be created from the client so that the product identification code is input. In the 3D CAD, the input product identification code is Based on the product management information (3D) 31, the three-dimensional model is specified. Then, the information of the corresponding three-dimensional model is read from the three-dimensional CAD server computer 1 to the client. Next, the read 3D model drawing is pasted on the electrical component assembly work instruction diagram, and the drawing sheet name for identifying the drawing and the 3D model name pasted on the drawing are stored as drawing management information (step S402). ). The drawing management information 36 is information for managing the created drawing, and includes, for example, a drawing sheet name 361 and a three-dimensional model name 362 as shown in FIG.

  Next, based on the electrical component mounting information 33, a serial number is set to the assigned logical coordinates, and the balloon number of the set number is assigned to the corresponding electrical component of the three-dimensional model on the drawing (step S403). . The balloon number is a balloon drawn from a corresponding part and the number is entered in a circle symbol ahead of it. Here, the serial number set in the logical coordinates represents the work order of assembling the electrical parts into the product, for example, in the order in which the coordinates are rearranged in ascending order based on the logical coordinates representing the physical positions of the electrical parts. A setting method is determined in advance, such as numbering. Also, a plurality of numbering methods may be defined so that the method of numbering can be arbitrarily selected. Next, the contents of the electrical component mounting information 33 are rearranged in the order of the serial numbers set in step S403, edited into a list format, and pasted on the electrical component assembly work instruction diagram (step S404). Finally, the created electrical component assembly work instruction diagram and drawing management information are sent to the three-dimensional CAD server computer 1 and stored in the three-dimensional database 3, and the process ends (step S405).

  FIG. 18 shows an example of an electrical component assembly work instruction diagram created by the electrical component assembly work instruction diagram creation process according to this example. In the electrical component assembly work instruction diagram 71 of FIG. 18, the drawing of the 3D model created by 3D CAD is pasted on the left side as the mounting diagram 72, and the contents of the electrical component mounting information 33 are edited on the right side in the form of a list. This is pasted as a mounting list 73. The mounting list 73 is composed of number 75, logical coordinates 76, instrument number 77, part name 78, model 79, rating 80, and the like. In the mounting diagram 72, the number corresponding to each electrical component is displayed as a balloon number 74, and by referring to the mounting list 73 of the number corresponding to the balloon number 74, information on the electrical component can be confirmed. Can do.

  As described above, in this example, the electrical component assembly work instruction diagram can be automatically created by pasting the three-dimensional model and the electrical component mounting information on the electrical component assembly work instruction diagram. In addition, since the assembly order can be automatically determined from the logical coordinates, the number of steps for creating the electrical component assembly work instruction diagram can be reduced.

  Data is sequentially registered in the electrical component mounting information 33 by logical coordinates, appliance number assignment processing, and electrical component assembly work instruction drawing creation processing. In FIG. 7, an example of registered data is shown by (A), (B), and (C) in the order of those processes. FIG. 7A shows the result of the electrical part identification process (step S302) of the logical coordinate / appliance number assigning process in the electrical part mounting information 33 for the part corresponding to the electrical part among the constituent parts of the three-dimensional model. In the example, the dimension model name 331, the hierarchy name 332, the XYZ 333, and the part name 337 are set, and the logical coordinate 334 is set as a result of the logical coordinate assignment process (step S303).

  FIG. 7B shows the result that the component name of the electrical component mounting information 33 matches the component name of the circuit attribute information 42 of the electrical CAD as a result of the device number assignment processing (step S306) of the logical coordinate and device number assignment processing.

  In this example, as described above, the information designed by the three-dimensional CAD and the information designed by the electric CAD are automatically associated and linked. As a result, it is possible to display on the three-dimensional model which part of an actual product an arbitrary electrical component on the electrical circuit diagram of the electrical CAD is attached to. On the contrary, it is also possible to display on the electrical circuit diagram where the arbitrary electrical component on the three-dimensional model of the three-dimensional CAD is described in the electrical circuit diagram.

In 3D CAD, the product management information (3D) is based on the input product identification code. ) 31 to specify the three-dimensional model name. Then, the information of the corresponding three-dimensional model is read from the three-dimensional CAD server computer 1 to the client. Next, the read three-dimensional model is displayed on the screen of the client display device (step S132). Next, when the user selects a specific electrical component of the displayed three-dimensional model with a mouse or a keyboard, the electrical component mounting information 33 is referred to, and the appliance number of the corresponding electrical component is specified (step S133). Next, the product identification code and the specified appliance number are transferred to the electric CAD, and a display request for the corresponding electric circuit diagram is made (step S134).

  Next, in the electric CAD that has received the display request, the product management information (electricity) 41 is referred to based on the product identification code input from the three-dimensional CAD, and the electric circuit diagram name is specified. Then, the information of the corresponding electric circuit diagram is read from the electric CAD server computer 2 to the client (step S135). Next, based on the appliance number input from the three-dimensional CAD, the circuit attribute information 42 is referred to and the corresponding electrical component is specified (step S136). Next, an electrical circuit diagram is displayed on the screen of the client display device, and the specified electrical component portion is highlighted (step S137). Note that the display method can be other display methods that the user can easily distinguish in addition to the highlight display, as described in the electrical component attachment position display process.

  FIG. 20 shows a screen display example by the electric circuit diagram description position display processing according to this example. FIG. 20A shows a three-dimensional model 71 displayed on the display device of the client by three-dimensional CAD.

Thereby, the maintenance worker can carry the portable terminal device at the time of inspection of the control system, maintenance work, etc., so that each drawing can be referred to at an arbitrary place such as the vicinity of the device at the site.

  In addition, the same software as the client computer is installed in the mobile terminal device, and the necessary 3D CAD data and electrical CAD data are read by communicating with the 3D CAD server computer 1 or the electrical CAD server computer 2 by wireless communication. The functions of the electric component attachment position display and the electric circuit diagram description position display described can also be realized. As a result, a server computer is installed in a central control room of a large-scale plant, etc., and maintenance workers carry the mobile terminal device during inspections and maintenance work, so that each drawing can be referred to at any place. be able to. In addition, when a product is assembled, an on-site worker carries the portable terminal device, so that each drawing can be referred to at the work site. Furthermore, when parts are added or changed during assembly work or the like, it is possible to correct data such as three-dimensional CAD data and electrical circuit diagrams while confirming actual devices at the work site.
