Description

Technical Field

[0001] The invention relates to a drawing management device, a drawing management system and a drawing management method. Background Art

[0002] As a method for identifying a target object such as a pump from 3D data of a factory, for example, Patent Document 1 discloses a method of identifying an unknown target object by generating 2D data from 3D data obtained by scanning the factory's appearance and comparing the 2D data with known 2D data.

[0003] Patent Document 1: Japanese Patent Publication No. 2017-120632 Summary of the invention

[0004] In Patent Document 1, since it is assumed that the known 2D data is the latest data, it is impossible to determine the unknown target object when the known 2D data is not the latest data. Here, various drawings are used in the design of the factory, including a refinement of the PFD (Process Flow Diagram), the P&ID (Piping and Instrument Diagram) of the PFD, and a 3D piping diagram (3D factory diagram) containing physical information in the P&ID. When correcting one of the drawings, such as the PFD, the necessary elements should also be reflected in the P&ID and the 3D piping diagram. However, in the factory, multiple persons in charge share the work of drawing correction, and sometimes the reflection work is shelved or the correction content is forgotten due to changes in the persons in charge or busyness. Therefore, the matching between the various drawings cannot be guaranteed, and the matching between the various drawings and the physical factory cannot be guaranteed. In particular, when P&IDs and 3D piping diagrams are produced based on PFDs that do not match the current state of the factory, the mismatched parts contained in the drawings will extend to other drawings, and the matching between the various drawings cannot be guaranteed, and further, the matching between the various drawings and the actual factory cannot be guaranteed.

[0005] Therefore, an object of the present invention is to provide a drawing management device, a drawing management system and a drawing management method that can ensure the matching between various drawings and further ensure the matching between various drawings and physical factories.

[0006] Several embodiments of the drawing management device include a processing unit and a communication unit, wherein the processing unit generates a virtual factory based on various drawings of the factory, and when any one of the various drawings is changed, the processing unit updates the virtual factory based on the change, and the processing unit notifies a specified notification destination of information related to the change of the updated virtual factory via the communication unit.

[0007] In this way, the matching between various drawings can be guaranteed, and then the matching between various drawings and the physical factory can be guaranteed.

[0008] In one embodiment, the processing unit may verify whether the elements changed when the virtual factory is updated are elements that need to be recorded in the various drawings when updated, and include the verification result in the information related to the changes of the updated virtual factory.

[0009] As a result, each person in charge can effectively understand whether the drawings he is responsible for need to be changed as the virtual factory is updated, thereby eliminating omissions in reflection and improving work efficiency.

[0010] In one embodiment, the processing unit may verify whether the elements changed when the virtual factory is updated are reflected in the various drawings at the time of the update, and include the verification result in the information related to the change of the updated virtual factory.

[0011] As a result, each person in charge can effectively understand whether the drawings he is responsible for need to be changed as the virtual factory is updated, thereby eliminating omissions in reflection and improving work efficiency.

[0012] In one embodiment, the processing unit may perform the verification on various drawings other than the changed drawing during the update.

[0013] Thereby, the verification can be performed more efficiently.

[0014] A drawing management system according to some embodiments includes the drawing management device described above and at least one terminal device capable of communicating with the drawing management device.

[0015] In this way, the matching between various drawings can be guaranteed, and then the matching between various drawings and the physical factory can be guaranteed.

[0016] Several embodiments of the drawing management method use a computer and include the following steps: a step of generating a virtual factory based on various drawings of the factory; a step of updating the virtual factory based on the change when any one of the various drawings is changed; and a step of notifying a specified notification destination of information related to the change of the updated virtual factory.

[0017] In this way, the matching between various drawings can be guaranteed, and then the matching between various drawings and the physical factory can be guaranteed.

[0018] According to the present invention, a drawing management device, a drawing management system and a drawing management method can be provided, which can ensure the matching between various drawings and further ensure the matching between various drawings and a physical factory.

DETAILED DESCRIPTION

[0026] Hereinafter, embodiments for implementing the present invention will be described with reference to the accompanying drawings. In each of the drawings, the same reference numerals represent the same or equivalent components.

[0027] (Drawing Management System)

[0028] Reference Figure 1 The configuration of the drawing management system 1 according to the present embodiment will be described.

[0029] The drawing management system 1 includes a drawing management device 10, a terminal device A corresponding to a first terminal device, a terminal device B corresponding to a second terminal device, and a terminal device C corresponding to a third terminal device. The drawing management device 10 can communicate with the terminal device A, the terminal device B, and the terminal device C via a network 20 such as the Internet. The number of terminal devices is not limited to three, and may be any number.

[0030] The drawing management device 10 is a PC (personal computer) or a computer such as a server belonging to a cloud computing system, but is not limited thereto.

[0031] The drawing management device 10 includes a processing unit 11 , a storage unit 12 , and a communication unit 13 .

[0032] The processing unit 11 includes one or more processors. The processor is, for example, a general-purpose processor such as a CPU (central processing unit) or a dedicated processor dedicated to a specific process. The processing unit 11 controls each part of the drawing management device 10 and performs processes related to the operation of the drawing management device 10.

[0033] The storage unit 12 includes one or more semiconductor memories, one or more magnetic memories, one or more optical memories, or a combination thereof. The semiconductor memory is, for example, a RAM (random access memory) or a ROM (readonly memory). The storage unit 12 stores information used for the operation of the drawing management device 10 and information obtained through the operation of the drawing management device 10. For example, in addition to storing information related to various drawings of the physical factory and the virtual factory VP, the storage unit 12 also stores information related to the expression rules, comparison rules, comparison results, registration history, and notification history of these. In addition, the storage unit 12 can also store information related to the terminal devices A to C of the notification destination, the addresses of each person in charge, and the business in charge.

[0034] The communication unit 13 includes one or more communication interfaces capable of communicating via, for example, the Internet, a gateway, and a LAN (local area network). The communication unit 13 receives information used for the operation of the drawing management device 10 and transmits information obtained by the operation of the drawing management device 10 .

[0035] The operation of the drawing management device 10 is realized by the processor included in the processing unit 11 executing a program stored in the storage unit 12. The program may be stored in a non-transitory computer-readable medium.

[0036] The terminal device A, the terminal device B, and the terminal device C are, for example, a mobile phone, a smart phone, a tablet computer, or a computer such as a PC (personal computer), but are not limited thereto. The terminal device A, the terminal device B, and the terminal device C can be appropriately installed with any application required for managing various drawings of the physical factory, and are used by personnel related to the various drawings. In addition, the personnel related to the various drawings are not limited to the person in charge of processing the various drawings, but may also include supervisors of various drawings, leaders of the revision team, supervisors of multiple drawings or the entire factory, etc.

[0037] Physical factories include, for example, factories that manage and control wellheads and their surroundings, including gas fields and oil fields, in addition to chemical and other industrial factories. In addition, physical factories may also include factories that manage and control power generation, including hydroelectric power generation, thermal power generation, and nuclear power generation, factories that manage and control environmental power generation, including solar power generation and wind power generation, and factories that manage and control dams and reservoirs.

[0038] In the above configuration, an external storage device that can communicate with the drawing management device 10 and the terminal device A, the terminal device B, and the terminal device C can also be responsible for a part or all of the processing of the storage unit 12 of the drawing management device 10. In addition to the above configuration, the drawing management system 1 can also have any 3D scanning device that can 3D scan the appearance of the physical factory, and any terminal device that can communicate with the 3D scanning device. In addition, the drawing management system 1 can also have any terminal device that can manage the entire system.

[0039] (First Processing Example)

[0040] Reference Figure 2 A first processing example of the drawing management system 1 according to this embodiment will be described. The first processing example corresponds to one embodiment of the drawing management method of the present invention.

[0041] First, it is assumed that drawing A1 created by person in charge A, drawing B1 created by person in charge B, and drawing C1 created by person in charge C are pre-registered in the storage unit 12 of the drawing management device 10. In this example, drawing A1 is a PFD (Process Flow Diagram). Drawing B1 is a P&ID (Piping and Instrument Diagram). Drawing C1 is a 3D piping diagram. The order of registering drawings A1, B1, and C1 is arbitrary, and the types of drawings A1, B1, and C1 are not limited to PFD, P&ID, and 3D piping diagram. The processing unit 11 of the drawing management device 10 generates a virtual plant VP1 based on drawings A1, B1, and C1 obtained from the storage unit 12, and stores it in the storage unit 12. For example, the processing unit 11 extracts elements such as valves or pipes included in drawings A1, B1, and C1 and the relationship between the elements by using an arbitrary method, and merges them without duplication to generate a virtual plant VP1. That is, the so-called "virtual factory" is a collection of data representing valves, pipes and other equipment in a physical factory and the relationship between the equipment, etc. For example, the "virtual factory" can also be described using a semantic data model.

[0042] The first processing example starts when the person in charge B uses the terminal device B to change the drawing B1 to create the drawing B2 and register the drawing B2 in the storage unit 12 of the drawing management device 10. In addition, by controlling access rights such as check-in / check-out, it is also possible to prevent other persons in charge B' from modifying the drawing B1 while the person in charge B is modifying the drawing B1.

[0043] In step S101, the processing unit 11 of the drawing management device 10 obtains drawings B1 and B2 of the same type from the storage unit 12 and compares drawings B1 and B2. In the first processing example, drawing B1 corresponds to the old drawing of the first type of drawings, and drawing B2 corresponds to the new drawing of the first type of drawings.

[0044] In step S102, the processing unit 11 of the drawing management device 10 determines whether there is a difference ΔB between the drawing B1 and the drawing B2. For example, the drawing B1 and the drawing B2 are drawings of the same type with the same or similar elements and expressions, so the processing unit 11 can also use any image analysis technology to perform the determination in step S102, but is not limited to this. For example, the processing unit 11 performs the determination in step S102 after converting the drawings B1 and the drawings B2 into any comparison model including elements and information indicating the relationship between the elements. If there is a difference ΔB (step S102: Yes), the process proceeds to step S103. If there is no difference ΔB (step S102: No), the process ends. However, if there is no difference ΔB, the processing unit 11 notifies the terminal device B via the communication unit 13 that there is no difference ΔB. As a result, the person related to the drawing B can recognize the fact that the drawing B is newly registered and confirm that there is no change in the registered drawing B. In addition, the so-called no difference ΔB can be considered that only the number of revisions of drawing B has increased, but the relevant personnel of drawing B can recognize this and grasp the fact of the unchanged revision or draw attention to it. In addition, it can prevent unnecessary notification to the relevant personnel of other drawings.

[0045] When the process proceeds from step S102 to step S103, in step S103, the processing unit 11 of the drawing management device 10 reflects the difference ΔB in the virtual plant VP1 obtained from the storage unit 12. As a result, the virtual plant VP1 is updated to the virtual plant VP2. The processing unit 11 stores information related to the change of the updated virtual plant VP2 in the storage unit 12. In addition, the information can include information such as the update content or the update time.

[0046] In step S104, the processing unit 11 of the drawing management device 10 notifies the specified notification destination such as the terminal device A, the terminal device B or the terminal device C via the communication unit 13 of information related to the change of the virtual factory VP2. For example, the person in charge A who receives the notification via the terminal device A recognizes the new change, reflects the necessary changes in the new change to the drawing A1 using the terminal device A, creates the drawing A2, and registers it in the storage unit 12 of the drawing management device 10. Here, in the first processing example, the drawing A1 and the drawing A2 are respectively equivalent to the second type of drawing. In addition, the processing unit 1 may automatically perform the notification of step S104 via the communication unit 13 when the virtual factory VP2 is updated. Alternatively, the processing unit 11 may also notify the establishment of a link (for example, URL, etc.) to the virtual factory VP stored in the storage unit 12 of the drawing management device 10 via the communication unit 13. In this case, the person in charge who receives the notification of the message can click the link to access the virtual factory VP stored in the storage unit 12 of the drawing management device 10.

[0047] According to the first processing example, the matching between various drawings and the matching between various drawings and the physical plant can be ensured. In addition, in the first processing example, the update of the virtual plant VP1 caused by the change of drawing B1 is described, but the same processing is performed when the drawing A1 or drawing C1 is changed.

[0048] (Second processing example)

[0049] Reference Figures 3 to 5 A second processing example of the drawing management system 1 according to this embodiment will be described. The second processing example corresponds to one embodiment of the drawing management method of the present invention.

[0050] When the categories of drawings are different, the elements contained in the drawings are also different, and the amount of information is also different. For example, the amount of information increases in the order of PFD, P&ID, and 3D piping diagram. In particular, the amount of information in PFD is very small. For example, sometimes even if the P&ID is changed, there is no need to reflect the change in the PFD. Specifically, suppose a manual valve is added to the P&ID. Since the manual valve is not recorded in the PFD, it is meaningless even if the person in charge of the PFD, A, is notified that the manual valve has been added. In addition, when the person in charge or the team in charge is responsible for multiple drawings, or when the persons in charge of multiple drawings collaborate with each other, sometimes changes in certain categories of drawings have been reflected in drawings of other categories. The second processing example is an example that takes these situations into consideration.

[0051] First, it is assumed that drawing A1 produced by person in charge A, drawing B1 produced by person in charge B, and drawing C1 produced by person in charge C are pre-registered in the storage unit 12 of the drawing management device 10. In addition, the registration order of drawings A1, B1, and C1 is arbitrary, and the types of drawings A1, B1, and C1 are not limited to PFD, P&ID, and 3D piping diagrams. The processing unit 11 of the drawing management device 10 generates a virtual plant VP1 based on drawings A1, B1, and C1, and stores it in the storage unit 12, similarly to the first processing example.

[0052] The second processing example starts when the person in charge B changes the drawing B1 using the terminal device B to create the drawing B2 and registers the drawing B2 in the storage unit 12 of the drawing management device 10. In this example, the change from drawing B1 to drawing B2 is the addition of a manual valve (M-Valve) MV501 and a control valve (C-Valve) CV203.

[0053] In step S201, the processing unit 11 of the drawing management device 10 obtains drawings B1 and B2 of the same type from the storage unit 12 and compares drawings B1 and B2. In the second processing example, drawing B1 corresponds to the old drawing in the first type of drawings, and drawing B2 corresponds to the new drawing in the first type of drawings.

[0054] In step S202, the processing unit 11 of the drawing management device 10 determines whether there is a difference ΔB between the drawing B1 and the drawing B2 in the same manner as in step S102. If there is a difference ΔB (step S202: Yes), the process proceeds to step S203. On the other hand, if there is no difference ΔB (step S202: No), the process ends. In this example, the difference ΔB corresponds to the addition of MV501 and CV203.

[0055] When entering step S203 from step S202, in step S203, the processing unit 11 of the drawing management device 10 reflects the difference ΔB in the virtual factory VP1 obtained from the storage unit 12. As a result, the virtual factory VP1 is updated to the virtual factory VP2. In this example, the virtual factory VP2 is obtained by adding MV501 and CV203 to the virtual factory VP1. That is, the so-called virtual factory VP2 refers to the virtual factory VP1 that represents the structure of the physical factory so far, corresponding to the changes such as the addition or deletion of elements in various drawings, and reflects the changes and is updated. In addition, various drawings are used for the design of the factory. The changes in various drawings are finally reflected in the physical factory. And when the changes are accurately reflected by the operator, etc., the various drawings are consistent with the physical factory. However, before the design contents recorded in various drawings are reflected in the physical factory, the virtual factory VP is the data (future factory image) that integrates the drawing group used for factory design, which is not completely consistent with the physical factory.

[0056] Here, Figure 4 This shows an example of a data table including information on whether or not elements such as main instruments constituting virtual factories VP1 and VP2 are elements that need to be recorded in each drawing. Figure 4 In the table, “○” indicates a necessary element, and “×” indicates an unnecessary element. Figure 4 The data table shown is stored in the storage unit 12 of the drawing management device 10, and is appropriately referred to by the processing unit 11. Figure 4 In the data table shown in FIG. 1 , for example, the control valve is an element that needs to be recorded in the PFD, P&ID, and 3D piping diagram. On the other hand, it can be seen that the manual valve is an element that does not need to be recorded in the PFD, but needs to be recorded in the P&ID and 3D piping diagram. Therefore, in step S204, the processing unit 11 of the drawing management device 10 refers to Figure 4 The data table shown verifies, in drawings A1, B2, and C1, whether the elements changed when the virtual factory VP2 is updated are elements that need to be recorded in various drawings when the virtual factory VP2 is updated. The processing unit 11 includes the result of the verification in the information related to the change of the virtual factory VP2. Instead, the update from the virtual factory VP1 to the virtual factory VP2 is triggered by the change from drawing B1 to drawing B2. Therefore, the processing unit 11 can also perform the verification of step S204 on drawings A1 and C1 other than drawing B2. Thereby, the verification of step S204 is further validated. In this example, the processing unit 11 obtains the verification result that MV501 is not an element that needs to be recorded in drawing A1 but is a necessary element recorded in drawing C1, and CV203 is an element that needs to be recorded in drawings A1 and C1.

[0057] In step S205, the processing unit 11 of the drawing management device 10 verifies whether the elements that are changed when the virtual factory VP2 is updated and that are verified as elements that need to be recorded in various drawings in step S204 are reflected in various drawings in drawings A1, drawing B2, and drawing C1 respectively. The processing unit 11 includes the result of the verification in the information related to the change of the virtual factory VP2. Instead, the update from the virtual factory VP1 to the virtual factory VP2 is triggered by the change from drawing B1 to drawing B2. Therefore, the processing unit 11 can also perform the verification of step S205 on drawings A1 and drawing C1 other than drawing B2. Thereby, the verification of step S205 is further validated. In this example, the processing unit 11 obtains the verification results that MV501 is not reflected in drawing C1, and CV203 is reflected in drawing A1 but not in drawing C1.

[0058] In step S206, the processing unit 11 of the drawing management device 10 notifies the terminal device A, the terminal device B, or the terminal device C of the information related to the change of the virtual factory VP2 via the communication unit 13. Figure 5 In the form of a list shown, information related to the change of the virtual factory VP2 is notified to a predetermined notification destination such as the terminal device A, the terminal device B or the terminal device C. Figure 5 In the table, "√" indicates that the update has been reflected. "×" indicates that the update has not been reflected. "-" indicates an unnecessary element. A star mark indicates a drawing that triggers the VP update. In addition, the mark (symbol) is an example and is not limited to this. Figure 5In the notification illustrated in the example, each person in charge who receives the notification via each terminal device can confirm (1) information related to the update from the virtual factory VP1 to the virtual factory VP2, (2) information related to whether the elements constituting the virtual factory VP2 are elements that need to be recorded in various drawings, (3) information related to whether the elements constituting the virtual factory VP2 have been reflected in various drawings, and (4) the type of the drawing that becomes the trigger for updating the virtual factory VP1 to the virtual factory VP2. In this example, the person in charge A who receives the notification via the terminal device A can confirm that (1) MV501 and CV203 are added to the virtual factory VP1, (2) MV501 is an element that does not need to be recorded in the drawing A1, CV203 is an element that needs to be recorded in the drawing A1, (3) CV203 has been reflected in the drawing A1, and (4) the drawing that becomes the trigger for updating the virtual factory VP1 to the virtual factory VP2 is the drawing B. In this case, the person in charge A does not need to change the drawing A1. On the other hand, the person in charge C who receives the notification via the terminal device C can confirm that (1) MV501 and CV203 are added to the virtual factory VP1, (2) MV501 and CV203 are elements that need to be recorded in the drawing C1, (3) MV501 and CV203 are not reflected in the drawing C1, and (4) the drawing that triggers the update of the virtual factory VP1 to the virtual factory VP2 is the drawing B. In this case, the person in charge C adds MV501 and CV203 to the drawing C1 using the terminal device C to create the drawing C2, and registers it in the storage unit 12 of the drawing management device 10. However, the form of the notification is not limited to Figure 5 The list format shown can be changed appropriately according to the notification object or purpose. In the second processing example, the drawing A1 corresponds to the second type of drawing, and the drawings C1 and C2 correspond to the third type of drawings.

[0059] Furthermore, in step S206, the processing unit 11 of the drawing management device 10 may notify all relevant personnel of the information related to the change of the virtual factory VP2 via the communication unit 13, or may notify only the necessary information to the persons in charge of various drawings. For example, the processing unit 11 may notify only the person in charge of drawing A of the information related to the change of the virtual factory VP2 via the communication unit 13, and whether the change in drawing A is necessary. In addition, for example, Figure 5As shown, only when a mark (e.g., "×") is marked indicating that there are elements that are changed when the virtual factory VP2 is updated, such as elements that are not reflected in the drawing C, the processing unit 11 may notify the person in charge of the drawing C, etc., via the communication unit 13 of the content of the elements that are not reflected in the drawing C. Alternatively, the processing unit 11 may notify each terminal device of information related to the change of the virtual factory VP via the communication unit 13 when a prescribed time has passed since the update of the virtual factory VP, or when the amount of information that should be reflected in various drawings accompanying the update of the virtual factory VP exceeds a prescribed threshold. In addition, the "prescribed time" and the "prescribed threshold" are appropriately set by each person in charge. Thus, each person in charge can appropriately adjust the frequency of operations associated with the notification. Therefore, it is useful to avoid each person in charge from feeling cumbersome or having low work efficiency due to notifying a small amount of changes one by one.

[0060] According to the second processing example, since each person in charge can efficiently understand whether the drawings he is responsible for need to be changed in accordance with the update of the virtual factory VP, the efficiency of the drawing change is improved. In addition, in the second processing example, the update of the virtual factory VP1 in accordance with the change of the drawing B1 is described, but the same processing is performed when the drawing A1 or the drawing C1 is changed.

[0061] The present invention has been described above based on the drawings and embodiments, but it should be noted that various deformations or changes can be made based on the present invention for those skilled in the art. Therefore, these deformations or changes should be understood to be included in the scope of the present invention. For example, the functions included in each step can be reconfigured in a logically non-contradictory manner, or a plurality of steps can be combined into one or divided into a plurality of steps.

[0062] For example, in the above-mentioned processing example, each person in charge may access the drawing management device 10 using each terminal device at any time in order to confirm the latest status of the virtual factory VP.

[0063] In the above processing example, the information related to the change of the virtual factory VP is described. Figure 5In the example shown in the list format, the information is notified to the person in charge A, B, or C. However, since there are many elements constituting the virtual plant VP, if the information related to the change of the virtual plant VP can be filtered and notified to the person in charge A, B, or C, the work efficiency is improved. Therefore, as a modified example, the processing unit 11 of the drawing management device 10 filters the information related to the change of the virtual plant VP based on the filtering conditions obtained from the terminal device A, B, or C via the communication unit 13. Then, the processing unit 11 of the drawing management device 10 notifies the terminal device A, B, or C of the filtered information related to the change of the virtual plant VP via the communication unit 13. In addition, the "filtering conditions" are (1) the current status of specific elements such as valves or pipes in the drawings for which the user is responsible, (2) whether it is necessary to reflect the elements related to the update of the virtual plant in the drawings for which the user is responsible, (3) the current status of drawings other than the drawings for which the user is responsible (especially drawings outside the user's responsibility but with a high correlation with the drawings for which the user is responsible), (4) the current status of the entire virtual plant, or a combination thereof. In particular, (3) is useful for a supervisor who is in charge of the entire factory. In addition, the filtering condition can be appropriately set by the person in charge A, B, or C using the terminal device A, B, or C, for example.

[0064] In addition, in the above processing example, when the on-site operators replace or repair the parts of the factory, they sometimes do not refer to the drawings one by one, or do not fully follow the drawings. As a countermeasure, a 3D scanning device that can take pictures of the appearance of the physical factory can be used to grasp the current situation of the physical factory. The processing unit 11 of the drawing management device 10 can also update the virtual factory VP based on the comparison of the 3D pipeline diagram remade based on the 3D scanning data of the physical factory photographed by the 3D scanning device and the 3D pipeline diagram that has been made based on PFD or P&ID. In this way, the actual status of the physical factory, such as which equipment is set, how to set, and how to remove it, etc., in the equipment added or deleted in various drawings, can be grasped along with the changes in various drawings, and the virtual factory VP can be updated according to the actual status of the physical factory. Therefore, the matching of various drawings with the physical factory can be further improved. In addition, the information related to the change of the virtual factory VP can also include the production history of various drawings.

[0065] Possibility of industrial application

[0066] According to the present invention, a drawing management device, a drawing management system and a drawing management method can be provided, which can ensure the matching between various drawings and further ensure the matching between various drawings and a physical factory.
