Description

An embodiment of the present invention relates to a system for supporting the design of upgrade panels during plant upgrade engineering.

At plants that are already in operation, equipment may need to be replaced or new equipment may need to be introduced. In such plant renewal engineering work, the latest expansion and connection diagram for the plant is obtained. Even the latest expansion and connection diagram is often subject to revisions and changes made at the time without being reflected in the drawings. For this reason, it is necessary to investigate the condition of the panels installed at the actual site and update the expansion and connection diagram.

Conventionally, on-site surveys would involve measuring the dimensions of the equipment inside the existing panel using a tape measure and taking numerous photographs, bringing this data back with them to update the deployment and connection diagram, and then carrying out the renewal design on paper based on the updated deployment and connection diagram.

Therefore, depending on the know-how of the on-site investigator, measurements or photographs may be missed, making it necessary to conduct an on-site investigation again. If it is discovered that necessary information is missing in the final stages of the renewal design, redesign may be necessary, which significantly reduces the productivity of the renewal design.

For example, Patent Document 1 describes the design of a control panel using a three-dimensional model (3D structural drawing). Currently, such 3D structural drawings are generally easy to prepare, and their use is on the rise. In addition to electrical circuit information for the development and connection diagram, 3D structural drawings can also be associated with information on the dimensions of panels, units, etc. and stored in a database. If used in the design work for updated panels, it is expected to improve productivity.

Japanese Patent Application Publication No. 6-314318

The embodiment of the present invention has been made to solve the above problems, and aims to provide an update panel design support system that improves the efficiency of updating existing panels and updating panel design work.

An embodiment of the present invention includes an image data acquisition means for acquiring first image data including an entire existing panel installed in a plant, a position angle information detection means for detecting first position information and first angle information of the image data acquisition means, a first database storage means for storing a first three-dimensional structural drawing representing the entire existing panel and a second three-dimensional structural drawing corresponding to a unit constituting the existing panel, and a processing device for searching and extracting the first three-dimensional structural drawing from the first database means based on a feature amount of the first image data. The image data acquisition means acquires second image data acquired by photographing a part of the existing panel after acquiring the first image data. The position angle information detection means detects second position information and second angle information of the image data acquisition means when acquiring the second image data. The processing device searches and extracts the second three-dimensional structural drawing from the first database means based on the second image data, and associates the second three-dimensional structural drawing with the first three-dimensional structural drawing based on the distance between the image data acquisition means and the existing panel, the first position information, the first angle information, the second position information and the second angle information.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as in reality. Even when the same part is shown, the dimensions and ratios of each part may be different depending on the drawing.
In this specification and each drawing, elements similar to those described above with reference to the previous drawings are given the same reference numerals and detailed description thereof will be omitted as appropriate.

FIG. 1 is a schematic block diagram illustrating an updated board design support system according to an embodiment.
1, the updated board design support system 100 includes a camera (image data acquisition means) 13, a gyro sensor (position angle information detection means) 14, and a processing device 2. The camera 13 and the gyro sensor 14 are communicatively connected to the processing device 2. In this example, the camera 13 and the gyro sensor 14 are communicatively connected to a communication device 11, and the processing device 2 is communicatively connected to a communication device 10. The communication devices 10 and 11 are communicatively connected to each other via a communication line. As long as the camera 13 and the gyro sensor 14 can be communicatively connected to the processing device 2, the communication connection path is not limited to this.

The camera 13 and the gyro sensor 14 are, for example, a portable terminal configured as one unit. This portable terminal preferably has a display unit capable of displaying captured images and also displaying information transmitted by the processing device 2. A portable terminal in which the camera 13 and the gyro sensor 14 are integrated may be referred to as the camera 13, etc. below. The gyro sensor 14 has a position detection function. Since the camera 13, etc. is integrated with the gyro sensor 14, the gyro sensor 14 can collect information on the position and angle of the camera 13. The camera 13, etc. transmits information on the position and angle of the camera 13 acquired by the gyro sensor 14 to the communication device 11 together with image data acquired by the camera 13.

The processing device 2 is communicatively connected to the communication device 10, and receives image data from the camera 13 etc., and information on the position and angle of the camera 13 etc., transmitted via the communication devices 11 and 10. The processing device 2 is connected to an input device 8 such as a keyboard or mouse, and executes a predetermined process based on the information from the communication device 10 and the input information from the input device 8, and outputs the desired output to, for example, a display device 1 connected to the processing device 2.

An example of the configuration of the processing device 2 will be described. The processing device 2 has an arithmetic processing unit 4 and an image processing unit 3. The arithmetic processing unit 4 executes a predetermined process based on input information. The predetermined process is, for example, an image recognition function executed according to a program stored in a storage device (not shown). The image processing unit 3 executes image processing to obtain a desired display output based on the results of calculations performed by the arithmetic processing unit 4, for example, according to information input from an input device 8.

The processing device 2 further has a 3D structural drawing CAD processing section 6, an existing board 3D structural drawing library 5, and an updated board 3D structural drawing library 7. The 3D structural drawing CAD processing section 6 accesses the existing board 3D structural drawing library 5 and the updated board 3D structural drawing library 7, and uses the 3D structural drawing CAD processing section 6 to create, edit, and delete each 3D structural drawing. The processing device 2 also uses the arithmetic processing section 4, image processing section 3, and 3D structural drawing CAD processing section 6 to design the updated board using the 3D structural drawing stored in the 3D structural drawing library. The 3D structural drawing is structural drawing data created by three-dimensional (3D) CAD and can be used with software compatible with 3D CAD, and can be associated with electrical connection information, etc., in addition to the dimensions of each part, as described below.

The processing device 2 is, for example, an information processing device operated by an arithmetic processing device, such as a computer terminal or a server. The communication devices 10 and 11 are, for example, access points for wireless communication.

The on-site surveyor 12 carries a camera 13 or the like and goes to the site where the existing panel 15 is installed, and photographs the existing panel 15. The photographed image data of the existing panel 15 is sent to the processing device 2 via the communication devices 11, 10, together with information on the position and angle of the camera 13 or the like. The processing device 2 searches the existing panel 3D structural drawing library 5 for 3D structural drawings corresponding to the existing panel 15 and the units 17 etc. mounted on the existing panel 15, based on the received image data and the information on the position and angle of the camera 13 or the like.

The processing device 2 updates the information of the 3D structural drawing corresponding to the existing panel 15 based on image data of the existing panel 15 and information on the position and angle of the camera 13, etc. Updating the information of the 3D structural drawing means modifying the information of the units actually installed, etc., of the original 3D structural drawing corresponding to the existing panel based on image data, etc. of the existing panel 15 installed on-site, and creating a 3D structural drawing corresponding to the latest existing panel 15 with the modified content.

2A and 2B are schematic diagrams illustrating a part of an updated board design support system according to an embodiment.
2(a) and 2(b) show examples of 3D structural drawing databases 50, 70 stored in the existing board 3D structural drawing library 5 and the updated board 3D structural drawing library 7.
2(a), the 3D structural drawing database 50 stored in the existing board 3D structural drawing library 5 includes a 3D structural drawing 150 of the entire board. Also, the 3D structural drawing database 70 stored in the updated board 3D structural drawing library 7 includes a 3D structural drawing 150a of the entire board. The 3D structural drawings 150, 150a of the entire board are associated with the board name, and the board name is associated with information on the dimensions of the entire board and information on the devices housed therein. The information associated with the board name may include various information for identifying the board, such as information on the installation location of the board and the serial number.

As shown in FIG. 2(b), the 3D structural drawing database 50 of the existing board 3D structural drawing library 5 stores 3D structural drawings 170 of the units stored in the board. The 3D structural drawing database 70 of the updated board 3D structural drawing library 7 stores 3D structural drawings 170a of the new units to be stored in the board. In this example, the 3D structural drawing of the unit is shown as the data for 3D structural drawing 170a, but the existing board 3D structural drawing library 5 and the updated board 3D structural drawing library 7 already store 3D structural drawings of all the devices and equipment stored in the existing board and all the devices and equipment to be stored in the updated board.

The 3D structural diagrams of units stored in any of the 3D structural diagram libraries are associated with the unit name and unit number, and the unit number is associated with the unit's dimensional information as well as information on the installed I/O modules and I/O module connection information.

The database in the Existing Panel 3D Structural Diagram Library 5 is constructed from data from the time of design or the most recent renewal engineering, but as mentioned above, there may be differences from the actual configuration of the existing panel at the site. During an on-site survey at the time of the renewal engineering, the actual configuration of the existing panel, including differences in the configuration of the existing panel at the site, is investigated, and the 3D structural diagram database 50 in the Existing Panel 3D Structural Diagram Library 5 is updated to the latest state.

In the design work for the updated panel, the design work for the updated panel is carried out based on the 3D structural drawing database updated to the latest state and the specifications to be updated. When the design work for the updated panel is completed, the processing device 2 replaces the 3D structural drawing database after the design work is completed with the 3D structural drawing database of the existing panel.

The operation of the updated board design support system 100 according to the embodiment will be described.
FIG. 3 is a schematic diagram for explaining the operation of the updated board design support system according to the embodiment.
3 shows an existing panel 15 to be inspected on-site, a camera 13, etc. The existing panel 15 has a panel name for identifying the existing panel written on a plate 16, which is "P1102-P5" in this example. A unit 17 is provided on the existing panel 15. Note that the name of the unit 17 may be written on a plate or the like, but generally the unit name is not written on the plate.

The surveyor photographs the entire existing panel 15 and measures the distance between the camera 13 etc. and the existing panel 15 as an initial operation to identify the position in the image data of the photographed existing panel 15. The distance between the camera 13 etc. and the existing panel 15 is measured according to the principle of three-point surveying.

For example, the inspector holds the camera 13 etc. almost horizontally to photograph the entire existing board 15, and then, in the same position, tilts the camera 13 etc. downward to photograph the installation part at the bottom end of the existing board. The distance between the camera 13 etc. and the existing board 15 is calculated based on the holding height of the camera 13 etc. and the angle of the camera 13 etc. at this time. The camera 13 etc. transmits the measured data to the processing device 2. The processing device 2 calculates the distance between the camera 13 etc. and the existing board 15 from the height and angle information received from the camera 13 etc. The distance between the camera 13 etc. and the existing board 15 may be calculated by the camera 13 etc. and the result may be transmitted to the processing device 2. Also, after measuring the distance between the camera 13 etc. and the existing board 15, the entire existing board 15 may be photographed. The distance between the camera 13 and the existing board 15 is not limited to this, and may be measured more directly by detecting the position of the existing board 15 using the position detection function of the gyro sensor 14, or a separate tape measure may be used to measure the distance between the camera 13 and the existing board 15. In this case, the measured distance must be input manually or the like into the processing device 2.

The camera 13 etc. transmits image data (first image data) capturing an image of the entire existing panel 15, as well as position information (first position information) and angle information (first angle information) of the camera 13 etc. to the processing device 2.

4A and 4B are schematic diagrams for explaining the operation of the updated board design support system according to the embodiment.
FIG. 4A shows an example of image data DI captured by the camera 13 or the like.
As shown in Fig. 4(a), the image data (first image data) DI includes the panel name "P1102-P5" written on the plate of the existing panel 15. The image data DI also includes a full view of the existing panel 15. Since the 3D structural drawing of the existing panel 15 includes information regarding the dimensions of the housing and the like, the position of each part can be identified by setting a reference position in the image data DI and photographing the existing panel 15. In this example, the position of the plate is set to the reference position of the existing panel.

The camera 13 etc. transmits the image data DI to the processing device 2. The processing device 2 uses an image recognition function implemented by the calculation processing unit 4, for example an image recognition program, to recognize the board name "P1102-P5" as a feature of the image data of the existing board, and identifies the existing board.

As shown in FIG. 4(b), the processing device 2 searches the 3D structural drawing database 50 of the existing board 3D structural drawing library 5 and extracts the 3D structural drawing (first three-dimensional structural drawing) 150 associated with the board name "P1102-P5". The processing device 2 can display the extracted 3D structural drawing 150 on the display device 1 according to the operation of the operator. Also, preferably, the on-site inspector can operate the camera 13 or the like to display the 3D structural drawing 150 extracted by the processing device 2 on the camera 13 or the like. In the above description, a plate with the board name written on it is used to identify the existing board, but this is not limited to this. For example, if the shape of the board's casing is characteristic, the image data and the 3D structural drawing may be directly compared to extract the desired 3D structural drawing. In that case, the processing device 2 is set to set a specific location of the existing board and the 3D structural drawing as the reference position.

5A and 5B are schematic diagrams for explaining the operation of the updated board design support system according to the embodiment.
As shown in Fig. 5(a), multiple units are stored in the image data DI of an existing panel. Parts A to D of the image data DI show four units stored in the panel. In this example, when the plate position is set as the reference position, parts A to D of the image data DI are arranged below the plate position in this order.

As shown in FIG. 5(b), the on-site inspector photographs the entire existing panel, including the plate that serves as the reference position for image data DI, and then photographs the units stored in the existing panel. The inspector photographs the target by tilting the camera 13 etc. downward from a state where the camera is focused on the plate, and focusing on part C. The camera 13 etc. transmits the photographed image data (second image data) DIC to the processing device 2 together with position information (second position information) and angle information (second angle information) of the camera 13 etc.

The processing device 2 extracts the features of the image data DIC using the image recognition function of the calculation processing unit 4, searches the 3D structural drawing database of the existing board 3D structural drawing library 5, and extracts the 3D structural drawing 170 that matches the extracted features.

The processing device 2 associates the 3D structural drawing identified by the image data DIC with the 3D structural drawing corresponding to the existing board. When associating, information on the placement position on the existing board is also associated based on the distance between the camera 13, etc. and the existing board 15, and the position information and angle information of the camera 13, etc. received together with the image data DIC.

Then, the on-site investigator tilts the camera 13 etc. further downward and takes a picture so as to focus on part D. The camera 13 etc. transmits the captured image data DID to the processing device 2 along with position information and angle information of the camera 13 etc. The processing device 2 searches for and extracts a 3D structural diagram that matches the features of the image data DID, just as in the case of image data DIC. Similarly, for parts A and B, the processing device 2 obtains image data, position information and angle information of the camera 13 etc. by photographing them with the camera 13 etc., and based on this, searches for and extracts a 3D structural diagram of the corresponding unit.

In this example, a 3D structural drawing 150 corresponding to the existing panel 15 is associated with a 3D structural drawing 170 corresponding to a unit 17 that is stored in advance in the existing panel 15. These 3D structural drawings and their associations are updated with the 3D structural drawing of the unit identified by the image data DIC, DID, etc.

6A and 6B are schematic diagrams for explaining the operation of the updated board design support system according to the embodiment.
In the embodiment of the design support system 100 for updating a panel, modules mounted on a unit housed in an existing panel 15 are also registered in a 3D structural drawing, and the information is associated with the existing panel and the updated panel. Therefore, the 3D structural drawing of the modules mounted on the unit can also be identified by photographing them.

As shown in FIG. 6(a), for image data DID corresponding to portion D of image data DI of the existing panel, an on-site inspector photographs the camera 13, etc., in this example, by changing the angle from left to right. For example, first, the camera 13, etc. is aimed so as to focus on the leftmost module and image data DID1 is acquired. The camera 13, etc. transmits the acquired image data DID1 and position information and angle information of the camera 13, etc. to the processing device 2. The processing device 2 performs image recognition of the image data DID1, and searches for and extracts a 3D structural drawing 171 that matches the features of the image data DID1.

The on-site investigator points the camera 13 further to the right and acquires image data DID2. The acquired image data DID2 is subjected to image recognition by the processing device 2 in the same manner as described above, and the 3D structural drawing 172 is searched for and extracted.

The extracted 3D structural drawing is linked to the 3D structural drawing of the existing board after the placement position is identified based on the distance between the camera 13 etc. and the existing board 15, and the position information and angle information of the camera 13 etc. The 3D structural drawing may be linked hierarchically, such as existing board-unit-module.

After extracting the 3D structural diagram of the module to be mounted on the unit, the processing device 2 may perform image recognition of the wiring number of the module and associate information regarding the wiring with the 3D structural diagrams 171 and 172 of the module.

7A and 7B are schematic diagrams for explaining the operation of the updated board design support system according to the embodiment.
7(a) and 7(b), in the existing panel 3D structural drawing library 5, the 3D structural drawing database 50 is updated to a 3D structural drawing database 50a. For units stored in the panel, 3D structural drawings are extracted from image data, and the placement positions within the existing panel are identified from position information and angle information of the camera 13, etc.

The unit corresponding to part A of the image data DI is designated as unit A' in the updated 3D structural drawing 50a and is stored in the top row of the board. The unit corresponding to part B is designated as unit B' in the updated 3D structural drawing 50a and is stored in the second row from the top of the board. The unit corresponding to part C is designated as unit 170a in the updated 3D structural drawing 50a and is stored in the third row from the top of the board. The unit corresponding to part D is designated as unit 170b in the updated 3D structural drawing 50a and is stored in the bottom row of the board.

In the embodiment of the renewal panel design support system 100, the 3D structural drawing database 50 of the existing panel 3D structural drawing library 5 stores data based on the latest information, but in the case of renewal engineering, changes may be made to the existing panel on-site that are not reflected in the database. In this example, the units in the top and second row from the top have been replaced with products from company A and company B, which do not exist in the 3D structural drawing database. Also, in the bottom unit 170b, the Xth module has been changed.

When such changes are made that are not reflected in the 3D structural diagram database, the 3D structural diagram of the changed unit, etc. may not exist in the 3D structural diagram database. In such a case, in the embodiment of the updated panel design support system 100, dummy units and dummy modules are registered in the 3D structural diagram database for the units and modules that do not exist, and the dummy units are associated with units A' and B' corresponding to parts A and B, and the dummy module is associated with the Xth module of unit 170b.

Any number of dummy units and dummy modules can be stored, and necessary information for the design work of the update board, such as information on dimensions, information on the functions of the units, and information on the wiring to be connected, is input by the input device 8, etc.

In this way, the latest 3D structural drawing 50a of the existing panel, taking into account the results of the on-site survey, is stored in the 3D structural drawing database of the existing panel 3D structural drawing library 5.

8A and 8B are schematic diagrams for explaining the operation of the updated board design support system according to the embodiment.
The design work for the renewal panel is carried out based on the latest 3D structural drawing 50a of the existing panel, which takes into account the results of the on-site survey shown in FIG. 8(a).
The operator of the processing device 2 (the designer of the updated panel) reads out, for example, the 3D structural drawing 50a of the latest existing panel from the existing panel 3 structural drawing library 5, and designs each of the units A" to D" shown in Fig. 8(b) according to the design specifications of the updated panel. In this way, the updated panel design support system 100 of the embodiment can design the updated panel based on the 3D structural drawing of the latest existing panel, making it possible to streamline the design work and improve productivity.

FIG. 9 is an example of a flowchart for explaining the operation of the updated board design support system according to the embodiment.
A series of operations of the updated board design support system 100 according to the embodiment will be described below with reference to a flowchart.
9 , in step S1, an inspector photographs the existing panel 15 installed at the site using the camera 13 or the like. The first photograph of the existing panel 15 is taken so as to include a full view of the existing panel 15, including a plate that serves as a reference position. The photographed image data DI, and position information and angle information of the camera 13 or the like are transmitted to the processing device 2.

In step S2, the processing device 2 uses image recognition to determine the board name contained in the image data DI and identify the corresponding existing board. The processing device 2 sets the plate on which the board name is written to the reference position.

In step S3, the processing device 2 searches the 3D structural drawing database of the existing panel 3D structural drawing library 5 to extract the 3D structural drawing corresponding to the identified existing panel. The processing device 2 makes the extracted 3D structural drawing corresponding to the existing panel displayable on the display device 1, and also displayable on the camera 13, etc.

In step S4, the inspector moves and tilts the camera 13 etc. to focus on the units in the existing panel 15 and take pictures. The captured image data, position information and angle information of the camera 13 etc. are sent to the processing device 2.

In step S5, the processing device 2 identifies the photographed unit based on the reference position, image data, position information and angle information of the camera 13, etc.

In step S6, the processing device 2 searches the 3D structural drawing database of the existing panel 3D structural drawing library 5.

In step S7, the processing device 2 determines whether or not there is a 3D structural diagram corresponding to the identified unit.

If a 3D structural drawing corresponding to the unit identified in step S7 exists, in step S9, the processing device 2 extracts the 3D structural drawing and registers it in the database in association with the 3D structural drawing corresponding to the existing panel.

If there is no 3D structural drawing corresponding to the unit identified in step S7, in step S8, the processing device 2 extracts a dummy unit and registers it in the database in association with the 3D structural drawing corresponding to the existing panel.

In the updated panel design support system 100, the above-mentioned processes from step S4 to step S9 are repeated according to the number of units to be stored in the existing panel. If there are multiple modules installed in the unit, the processes from step S4 to step S9 are repeated according to the number of modules.

In this way, the embodiment of the updated panel design support system 100 can update the 3D structural drawing corresponding to the existing panel, taking into account the configuration of the existing panel on-site.

In the above, the processing device 2 has been described as using the plate as the reference position, but when the plate is used as the reference position, other points on the existing board 15 are photographed by the camera 13, etc., and the angle between the reference position and the other points is measured by the gyro sensor 14, and the distance between the camera 13, etc. and the existing board 15 is found according to the principle of three-point surveying. In this case, the height of the camera 13, etc. is set in advance to the height of the surveyor, etc. According to this principle, the reference position is not limited to the plate, and may be other locations. For example, the distance between the camera 13, etc. and the existing board 15 can be found from the photographing angle of the top and bottom corners of the board's casing, and any location within the board can be found from the angle detected by the gyro sensor 14.

The effects of the updated board design support system 100 according to the embodiment will be described.
The replacement panel design support system 100 according to the embodiment includes a camera 13 and a gyro sensor 14, and the processing device 2 receives image data DI of the existing panel 15 acquired by the camera 13, etc., and position information and angle information of the camera 13, etc. The processing device 2 uses an image recognition function to determine information identifying the existing panel contained in the image data DI. The processing device 2 has a 3D structural drawing corresponding to the existing panel in advance, which is associated with information identifying the existing panel. Therefore, the replacement panel design support system 100 can identify the existing panel 15 based on the image data DI of the existing panel 15, and extract the corresponding 3D structural drawing that has been set in advance.

The updated panel design support system 100 of the embodiment is equipped with a gyro sensor 14, and is therefore able to acquire angle information from the camera 13, etc. The processing device 2 acquires the angle information from the camera 13, etc. together with image data, and is therefore able to identify the locations of units, modules, etc. housed within the existing panel based on this information, and use the image recognition function of the processing device 2 to search for and extract 3D structural drawings corresponding to those units or modules.

The image recognition function of the processing device 2 can also recognize and determine information related to characters in image data. Therefore, the update board design support system 100 can also obtain wiring information connected to units, modules, etc., associate it with the units, modules, etc., and store it in a database.

In this way, the embodiment of the renewal panel design support system 100 can sequentially collect the configuration details of the existing panel on-site in real time and reflect them in the 3D structural drawing of the existing panel. This makes it possible to streamline the updating work of the deployment connection drawing and the renewal panel design work.

The 3D structural diagrams created by the updated board design contain electrical connection information as well as three-dimensional shape information, so they can be used as elements for augmented reality (AR).

According to the embodiment described above, it is possible to realize an update panel design support system that improves the efficiency of update work for existing panels and update panel design work.
