Description

Technical Field

[0001] The present invention relates to a design support system, a drawing data editing support method, and a program.

Background Art

[0002] As a general design method for facilities such as water treatment facilities, there is a design method of creating a design drawing such as a piping flow diagram using CAD (Computer Aided Design). By using CAD, a piping flow diagram in which a plurality of members (valves, pumps, pipes, tanks, water tanks, etc.) are arranged can be created. Such a piping flow diagram is provided with drawing component information in which member identification information for identifying a member and specification information of the member are linked for each member. Here, as the member identification information, in many cases, a character string (type or name) indicating a rough classification of the member is used. The specification information is, for example, information on specification attributes indicating the diameter of a valve or the like. As a related technique, Patent Document 1 discloses a design layout integration system capable of performing the layout of members based on drawing data created by CAD drawing editing software.

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the components described in the embodiments are merely examples, and are not intended to limit the scope of the present invention thereto.

[0012] (First Embodiment) FIG. 1 is a block diagram showing the configuration of a design support system according to a first embodiment of the present invention. Referring to FIG. 1, the design support system 10 can communicate with an information processing terminal 20 via a communication network 30. The communication network 30 is a network such as the Internet. The information processing terminal 20 is a terminal capable of executing a CAD program. As the information processing terminal 20, for example, a personal computer (PC), a portable information terminal such as a tablet terminal, etc. can be used. The information processing terminal 20 can create a CAD drawing, which is a design drawing, by executing a CAD program. Here, it is assumed that a large-scale facility design of a water treatment facility is performed using CAD, and a plurality of piping flow diagrams are created as CAD drawings. Examples of the water treatment facility include a water purification plant, a sewage treatment plant, water production equipment (e.g., production equipment for industrial water, drinking water, pure water, ultrapure water, etc.), wastewater treatment equipment, waste liquid treatment equipment, and the like. Although only one information processing terminal 20 is shown in FIG. 1, a plurality of information processing terminals 20 can access the design support system 10.

[0013] The design support system 10 includes a drawing registration unit 11, an information extraction unit 12, an information storage unit 13, an information editing unit 14, a drawing update unit 15, and a database 16. The drawing registration unit 11 accepts the registration of at least one CAD drawing (drawing data) created by the information processing terminal 20. The CAD drawing includes drawing member information in which member identification information for identifying a member and specification information of the member are associated with each other for each member, and a plurality of members are arranged.

[0014] The information extraction unit 12 extracts drawing component information from the CAD drawings registered in the drawing registration unit 11. The information storage unit 13 saves the drawing component information extracted by the information extraction unit 12 in the database 16. The information editing unit 14 presents a component information list screen that displays at least component identification information and specification information for each component based on the drawing component information stored in the database 16, accepts editing of the specification information for each component on the component information list screen, and reflects the edited specification information in the drawing component information stored in the database 16. The drawing update unit 15 updates the drawing data registered in the drawing registration unit 11 based on the edited specification information reflected in the drawing component information stored in the database 16.

[0015] Figure 2 is a schematic diagram illustrating the drawing data editing support process of the design support system 10. The drawing data editing process will be explained in detail below with reference to Figures 1 and 2. Equipment designers 40 create CAD drawings 21 using information processing terminals 20. Here, the CAD drawings 21 will consist of multiple piping flow diagrams for a water treatment facility. Each piping flow diagram will include at least one component such as a valve, pump, rotating equipment, instrument, tank, water tank, packing material, filtration membrane, small equipment, piping, or fittings. Equipment designers 40 are, for example, equipment planners or equipment designers. Multiple equipment designers 40 can access the design support system 10 using multiple information processing terminals 20. Other workers authorized to access the system (e.g., purchasing managers, inventory managers, budget managers, production managers, etc.) can also view the information on the design support system 10.

[0016] After the equipment designer 40 creates a CAD drawing 21 on the information processing terminal 20, he / she accesses the design support system 10 via the communication network 30 and requests registration of the CAD drawing 21. In the design support system 10, the drawing registration unit 11 performs the drawing registration process in response to the registration request (step S10). In the drawing registration process, the drawing registration unit 11 presents the drawing registration screen 11a and accepts the registration of the CAD drawing on the drawing registration screen 11a. The drawing registration unit 11 holds the CAD drawing 21 (registered drawing data) that the equipment designer 40 has registered on the drawing registration screen 11a. The equipment designer 40 can register multiple CAD drawings 21 at once.

[0017] Once the CAD drawing 21 is registered, the information extraction unit 12 then performs the drawing component information extraction process (step S11). In the drawing component information extraction process, the information extraction unit 12 extracts drawing component information 22 from the CAD drawing 21. The drawing component information 22 includes a type name, which is component identification information, and specification attributes, which are specification information. The type name is composed of a string that indicates a general classification of the component and a string that indicates a detailed classification. Specification attributes include, for example, information such as bore diameter, valve number, specification symbol, valve body, and operating method for a valve.

[0018] Once the drawing member information 22 is extracted, the information storage unit 13 then performs the drawing member information storage process (step S12). In the drawing member information storage process, the information storage unit 13 stores the extracted drawing member information 22 in the database 16.

[0019] Figure 3 shows an example of drawing component information 22 stored in the database 16. The drawing component information 22 includes the fields "Type Name," "Specification Attributes," and "Sheet No." "Sheet No." refers to the number of the drawing in which the component is placed. If "Sheet No." is "1," it indicates that the component is placed in the first CAD drawing. The "Type Name" field stores the type names of all components included in the registered CAD drawing 21. The "Specification Attributes" field stores the specification attribute information of the component stored in the "Type Name" field.

[0020] Although Figure 3 shows only one "Specification Attributes" item, multiple items may be provided to store more detailed information. For example, if the component is a valve, multiple items such as bore diameter, valve number, specification symbol, valve body, and operating method may be provided as "Specification Attributes" items. In addition, the drawing component information 22 stored in the database 16 may include items to store information other than "Type Name," "Specification Attributes," and "Sheet No.".

[0021] After the drawing component information 22 is saved in the database 16, if a change in the specifications of a component occurs, the equipment designer 40 accesses the design support system 10 using the information processing terminal 20 and requests editing of the drawing component information 22. In the design support system 10, the information editing unit 14 performs drawing component information editing processing in response to the editing request (step S13). In the drawing component information editing processing, the information editing unit 14 presents a component information list screen 23 that displays at least the type name and specification attributes for each component based on the drawing component information 22 saved in the database 16. The information editing unit 14 accepts editing of the specification attributes for each component on the component information list screen 23 and reflects the edited content in the drawing component information 22 saved in the database 16.

[0022] Figure 4 shows an example of the component information list screen 23. The component information list screen 23 includes the fields "Type Name" and "Specification Attributes". The "Type Name" field displays the type names of all components included in the drawing component information 22 stored in the database 16. The "Specification Attributes" field displays the specification attribute information of the component displayed in the "Type Name" field. Although only one "Specification Attributes" field is shown in Figure 4, multiple fields may be provided to display more detailed information (for example, bore diameter, valve number, specification symbol, valve body, operating method, etc.).

[0023] The equipment designer 40 can select the "Specification Attributes" item of the component that is subject to specification change from the components displayed in the "Type Name" item on the component information list screen 23, and edit the displayed information. In this editing process, the equipment designer 40 can select and edit components displayed in the "Type Name" item individually, or select and edit multiple components simultaneously.

[0024] When the drawing component information 22 is edited, the drawing update unit 15 then performs a drawing update process (step S14). In the drawing update process, the drawing update unit 15 updates the CAD drawing 21 registered in the drawing registration unit 11 based on the specification attributes of the components edited by the information editing unit 14 from the drawing component information 22 stored in the database 16. The equipment designer 40 can download the CAD drawing 21 stored in the drawing registration unit 11 on the information processing terminal 20.

[0025] When the equipment designer 40 wants to check the registered CAD drawing 21, they can download the registered CAD drawing 21 and check its contents using CAD drawing editing software. The equipment designer 40 can also delete the registered CAD drawing 21 on the drawing registration screen 11a. Furthermore, the equipment designer 40 may further edit the downloaded CAD drawing 21 using CAD drawing editing software. For example, they may change the drawing component information 22, delete components, or add components. They may also re-register the edited CAD drawing 21 to the drawing registration unit 11. In this case, the drawing component information extraction process (step S10), drawing component information saving process (step S11), and drawing component information editing process (step S12) may be performed as appropriate for the edited CAD drawing 21.

[0026] According to the design support system 10 of this embodiment, the equipment designer 40 can easily and efficiently edit the specification attributes of components in multiple CAD drawings 21 when a change in component specifications occurs, by registering multiple CAD drawings 21 created on the information processing terminal 20 in the drawing registration unit 11. For example, when using CAD editing software, it is necessary to open each of the multiple CAD drawings 21 one by one, specify the component to be changed individually, and edit it. In contrast, in this embodiment, the component information list screen 23 shown in Figure 3 displays the "type name" and "specification attribute" information of all components. The equipment designer 40 can change the specifications of components in all CAD drawings 21 simply by editing the "specification attribute" of the component to be changed on the component information list screen 23.

[0027] (Second embodiment) Figure 5 is a block diagram showing the configuration of a design support system according to a second embodiment of the present invention. The design support system 10A of this embodiment differs from the design support system 10 shown in Figure 1 in that it omits the information editing unit 14 and the drawing update unit 15, and has an information addition unit 17 and a procurement data creation unit 18. The design support system 10A can be called a procurement data creation support system. The same reference numerals are used for the same components as those shown in Figure 1. To avoid duplication of explanation, detailed explanations of the same components are omitted here.

[0028] Figure 6 is a schematic diagram illustrating the information addition process and procurement data creation process of the design support system 10A. The information addition process and procurement data creation process will be described in detail below with reference to Figures 5 and 6. In this embodiment, it is assumed that the drawing member information extraction process (step S11) and the drawing member information saving process (step S12) shown in Figure 2 have been performed in advance.

[0029] The information addition unit 17 performs specification information addition processing in response to an information addition request from the information processing terminal 20 (step S15). In the specification information addition processing, the information addition unit 17 presents a member information list screen 23a based on the drawing member information 22 stored in the database 16. Figure 7 shows an example of the member information list screen 23a. The member information list screen 23a is the member information list screen 23 shown in Figure 4 with the item "Additional Member Information" added, and necessary information can be added for each member. The member information list screen 23a can be called an additional information input screen.

[0030] The information addition unit 17 accepts additional information for each component on the component information list screen 23a and links it as additional component information 24 to the component identification information (type name) of the corresponding component in the drawing component information 22 stored in the database 16. The additional component information 24 includes, for example, specification information necessary for procuring components that cannot be extracted from the CAD drawing 21. If the component is a valve, the additional component information 24 may include, for example, the valve's pressure class, fittings, fluid name, pressure, temperature, material, whether or not it is oil-free, the structure of the operating handle, the installation location, and other supplementary information necessary for procuring it.

[0031] Figure 8 shows an example of drawing member information 22 to which additional member information 24 is linked. Drawing member information 22 includes the "Type Name" item, the "Specification Attributes" item, and the "Sheet No." item shown in Figure 3, and also includes an additional "Additional Member Information" item. In the "Additional Member Information" item, the additional information of the member added by the information addition unit 17 is stored in the corresponding part of the member.

[0032] The ordering data creation unit 18 performs ordering data creation processing in response to an ordering data creation request from the information processing terminal 20 (step S16). In the ordering data creation processing, the ordering data creation unit 18 creates ordering data 26 based on the drawing member information 22 stored in the database 16. The equipment designer 40 selects the type name of the member to be ordered. The ordering data creation unit 18 creates ordering data 26 for each selected type name. The created ordering data 26 is displayed on the ordering data list screen 25. Figure 9 shows an example of the ordering data list screen 25. The ordering data list screen 25 is a screen that displays the created ordering documents and includes the ordering document number, the "Type Name" item shown in Figure 3, and the ordering conditions.

[0033] The ordering data creation unit 18 transmits the created ordering data 26 to the information processing terminal 20. The ordering data 26 can be provided in file formats such as PDF (Portable Document Format), Excel, CSV (Comma Separated Value), or text files. The equipment designer 40 can format the ordering data 26 output in file format into an order form on the information processing terminal 20.

[0034] The design support system 10A of this embodiment provides the following effects and advantages. Even for components of the same type (e.g., valves), the required detailed specifications differ depending on their location within the equipment. Since this detailed specification information is not included in the drawing component information 22 obtained from the CAD drawing 21, relying solely on the drawing component information 22 is insufficient when ordering components. Therefore, it is necessary to create ordering data by adding the detailed specification information of components that cannot be obtained from the CAD drawing 21 to the drawing component information 22. Traditionally, it was necessary to obtain component information (type name and specification attributes) of the components to be ordered from the CAD drawing 21, and then add the detailed specification information of the components to the obtained component information to create ordering data. This ordering process was extremely cumbersome and inefficient for workers.

[0035] In contrast, in this embodiment, the equipment designer 40 selects the component to be procured from the "Type Name" item on the component information list screen 23a shown in Figure 7 and writes detailed specification information of the component in the "Additional Component Information" item. This results in drawing component information 22 linked to the additional component information 24, as shown in Figure 8. In this way, detailed specification information can be added easily and efficiently for all components to be procured. Furthermore, the additional component information 24 written on the component information list screen 23 is automatically added to the created procurement data 26 displayed on the procurement data list screen shown in Figure 9. Moreover, if there are any edits to items other than the additional component information 24, these edits are also automatically reflected in the procurement data 26. Therefore, procurement work can be performed easily and efficiently.

[0036] Furthermore, various modifications and improvements are possible in the design support system 10A of this embodiment. For example, on the order data list screen 25, more detailed items may be provided as selection items necessary for creating order data. For example, selection items such as delivery time, components used within the unit, components used outside the unit, drawing number (sheet no.), installation location, and manufacturer may be provided. This will enable the ordering of more detailed components.

[0037] Furthermore, the design support system 10A may also include the information editing unit 14 and the drawing update unit 15 shown in Figure 1. In this case, the procurement data creation unit 18 may save the procurement data 26 to the database 16, and the information editing unit 14 may edit the procurement data 26 saved in the database 16. For example, the information editing unit 14 displays a list of multiple procurement data 26 saved in the database 16 on the component information list screen 23, and the equipment designer 40 edits the procurement data 26 to be edited on the component information list screen 23. The information editing unit 14 reflects the edited content of the procurement data 26 in the corresponding procurement data 26 saved in the database 16.

[0038] Furthermore, to simplify the process of adding additional component information 24, if the specification attribute (specification information) of the drawing component information 22 includes a specification symbol indicating the type of component, table information linking the specification symbol and standard specification information for each component may be pre-stored in the database 16. In this case, the information addition unit 71 may obtain the corresponding standard specification information as additional component information 24 from the table information based on the specification symbol included in the drawing component information 22. In addition, in the table information, the specification symbol may be linked to standard specification information specific to each equipment delivery destination. For example, even with the same specification symbol, the standard specification information can be changed for delivery destination A and delivery destination B, making it possible to efficiently set additional component information that is suitable for each delivery destination.

[0039] (Third embodiment) Figure 10 is a block diagram showing the configuration of a design support system according to a third embodiment of the present invention. The design support system 10B of this embodiment differs from the design support system 10A shown in Figure 5 in that it has a data linkage unit 19. The same reference numerals are used for components that are the same as those shown in Figure 5. To avoid repetition in the explanation, detailed descriptions of the same components are omitted here.

[0040] The data linkage unit 19 can communicate with the purchasing management system 50 via the communication network 30. The data linkage unit 19 works in conjunction with the purchasing management system 50 and provides the purchasing management system 50 with the ordering data creation unit 18. The purchasing officer can access the purchasing management system 50 using an information processing terminal (PC) 51 and format the ordering data 26 provided by the data linkage unit 19 into a purchase order. The purchasing officer then sends the purchase order to the manufacturer to order the parts.

[0041] Furthermore, the equipment designer 40 sends the purchase order, which has been prepared from the procurement data 26, from the information processing terminal (PC) 51 to the purchasing officer's information processing terminal (PC) 51. In this case, the purchasing officer sends the purchase order sent by the equipment designer 40 to the manufacturer and orders the parts.

[0042] According to the design support system 10B of this embodiment, the data linkage unit 19 provides the procurement data 26 to the purchasing management system 50, so procurement work can be carried out more efficiently. In addition, because data linkage with the purchasing management system 50 is possible, the equipment designer 40 can also check the ordering status of materials.

[0043] In the design support systems 10, 10A, and 10B of the first to third embodiments described above (hereinafter referred to as "the System"), a search means may be provided to search for inappropriate settings from the drawing component information 22 and additional component information 24 stored in the database 16. For example, if the search means detects an inappropriate setting, it may display an error indicating that fact. Here, an inappropriate setting means that non-existent information (e.g., valve number, specification symbol, etc.) or incorrect information has been set. The error display makes it easy to identify the parts of the drawing component information 22 and additional component information 24 that need to be corrected, thereby improving the efficiency of the correction work of the equipment designer.

[0044] Furthermore, this system may have a display means for displaying identification information of information processing terminals currently connected to this system via the communication network 30. The identification information of the information processing terminal may be, for example, the identification information (e.g., name) of the equipment designer currently using this system. In this case, the equipment designer can confirm the name of the equipment designer using the system, and thus be able to carry out their work in cooperation with collaborators.

[0045] Furthermore, this system may have recording means for recording the editing history of drawing component information 22 and additional component information 24 as log information along with date and time data. In this case, the equipment designer can perform editing work while checking the log information (editing history). Here, the log information may include the worker's identification information (e.g., name). This allows the equipment designer to check the editing work previously performed by collaborators.

[0046] Furthermore, in this system, the database 16 may be built on an internet-based storage area (e.g., a file server, cloud, etc.) that can be accessed by multiple people simultaneously.

[0047] Furthermore, while this system is primarily intended to support the design of water treatment facilities, its applications are not limited to water treatment facilities. Examples of applications include buildings (e.g., houses, commercial buildings, office buildings, factories, chemical plants, power plants, public facilities, etc.), structures (e.g., bridges, dams, tunnels, towers, etc.), transportation infrastructure (e.g., roads, railways, airports, etc.), machinery, electrical circuits, electronic equipment, vehicles (e.g., automobiles, railway cars, etc.), ships, home appliances, furniture, and more.

[0048] Furthermore, the components that can be handled by this system include, for example, valves (e.g., manual valves, air-operated valves, solenoid valves, electric valves, safety valves, etc.), pumps (e.g., water supply pumps, drainage pumps, sewage pumps, chemical injection pumps, etc.), rotating equipment (e.g., blowers, fans, agitators, speed reducers, etc.), instruments (e.g., pressure gauges, flow meters, thermometers, power meters, concentration meters, pH meters, level gauges, etc.), tanks (e.g., resin tanks, metal tanks, etc.), water tanks (e.g., concrete water tanks, etc.), packing materials (e.g., sand, gravel, activated carbon, biological carriers, adsorbents, resins, etc.), filtration membranes (e.g., microfiltration (MF) membranes, limiting filtration (UF) membranes, reverse osmosis (RO) membranes, etc.), small equipment (e.g., heat exchangers, dehumidifiers, UV oxidation devices, etc.), piping (e.g., resin pipes, metal pipes, etc.), and pipe fittings. The components listed above are just examples of components used in water treatment facilities, and it is also possible to handle components used in other equipment.

[0049] Furthermore, this system may be composed of a computer such as a CPU (Central Processing Unit) that operates according to a computer program (hereinafter referred to as "program") that describes the processing content as a procedure. For example, in the design support system 10, a storage unit may be provided that stores a program for causing the computer to execute screen registration processing (S10), screen component information extraction processing (S11), screen component information saving processing (S12), screen component information editing processing (S13), and drawing update processing (S14). In the design support system 10A, a storage unit may be provided that stores a program for causing the computer to execute screen registration processing (S10), screen component information extraction processing (S11), screen component information saving processing (S12), specification information addition processing (S15), and procurement data creation processing (S16). In the design support system 10B, a storage unit may be provided that stores programs for causing a computer to execute screen registration processing (S10), screen component information extraction processing (S11), screen component information saving processing (S12), specification information addition processing (S15), procurement data creation processing (S16), and data linkage processing. The storage unit may be, for example, memory such as ROM (Read Only Memory) or RAM (Random Access Memory), or HDD (Hard Disk Drive) or SSD (Solid State Drive).

[0050] The program may be provided via a network such as the Internet. Alternatively, the program may be recorded on a computer-readable storage medium, and the program recorded on this medium may be loaded into a computer and executed. Furthermore, two or more of the design support systems 10, 10A, and 10B of the first to third embodiments may be combined to construct a single system. [Explanation of Symbols]
