Description

Technical Field

[0001] Embodiments of the present invention relate to test operation support technology.

Background Art

[0002] When considering the test planning work of a nuclear power plant, an operator investigates a plurality of drawings such as a piping and instrumentation diagram (P&ID), an interlock block diagram (IBD), and a developed connection diagram (ECWD) in order to confirm the connection of piping, interlocks, and electrical connections. Hereinafter, the piping and instrumentation diagram may be referred to as P&ID, the developed connection diagram may be referred to as ECWD, and the interlock block diagram may be referred to as IBD.

[0003] Also, before performing the test on the test target equipment, installation of equipment by mechanical construction, installation of electrical components by electrical instrumentation construction, and confirmation test of electrical circuits by electrical instrumentation test are performed. The scope of transfer of each construction and test target equipment and the required date are presented to each group based on P&ID. In this case, the transfer means transferring the management of the test target equipment from the construction group to the test group.

[0004] Also, adjustment is performed in advance at the area adjustment meeting so that work interference does not occur. Also, the operator grasps the position of the valve or equipment to be operated during the test in advance with the design drawing or equipment layout drawing, and confirms the formal installation position by line check before the test. Also, during the test period, the commander judged the daily progress based on the completion status of the work schedule.

[0005] Since there are a huge number of drawings to be investigated, it takes time for the operator to find the necessary information. Furthermore, access to the information desired from among the multiple existing drawings is achieved by storing various drawing information in the core system and accessing it from this system.

Patent Document 1

[0007] During the planning of nuclear power plant tests, workers verify piping connections, interlocks, and electrical connections. This involves checking a vast number of documents, including P&ID, IBD, and ECWD. However, verifying which pages contain the necessary information and ensuring the documents are up-to-date is time-consuming and laborious.

[0008] Furthermore, during the period from construction to testing of a nuclear power plant, mechanical work is based on P&ID (Plant and Information Design), electrical instrumentation work is based on equipment layout diagrams and 3D CAD (Computer-Electrical Design Worksheet), and electrical instrumentation testing is based on ECWD (Electronic Construction Worksheet). Because each group uses different documents as the basis for their work, discrepancies can arise in the understanding of the scope of equipment to be transferred and the required dates, which can lead to the discovery of unfinished work within the scope of the equipment to be transferred after the transfer.

[0009] Furthermore, while the supervisor makes adjustments to prevent interference in the work area, they sometimes fail to consider height differences within the same area. As a result, interference with other work may be discovered just before the test, leading to delays due to changes in the process.

[0010] Furthermore, during line checks of the target equipment conducted before testing, workers confirm the installation status of the equipment based on P&ID. However, P&ID lacks information on the installation location of piping or equipment, and it takes time to confirm the placement height, installation location, and area.

[0011] Furthermore, in managing the progress of the trials, it is difficult to determine the scope of completion for P&ID, IBD, and ECWD, making it time-consuming and inefficient to grasp.

[0012] The embodiments of the present invention have been made in consideration of these circumstances, and aim to allow users to access the page containing the necessary information in the latest publications that should be consulted when planning tests for nuclear power plants in the shortest possible time. [Means for solving the problem]

[0013] The test work support system according to an embodiment of the present invention comprises one or more computers that perform processing to support test planning work and test progress management work in flow path verification tests and interlock tests of nuclear power plants, wherein the computers are configured to link the piping number information and equipment number information in piping instrumentation diagrams registered in a piping instrumentation diagram database to the piping number information and equipment number information in 3D CAD drawings registered in one or more other databases, to link the equipment number information in equipment layout diagrams registered in the other databases using the equipment number information registered in the piping instrumentation diagram database as a key, to the equipment number information in equipment layout diagrams registered in the other databases using the equipment number information registered in the piping instrumentation diagram database as a key, to the electrical circuit information in deployment connection diagrams registered in the other databases using the electrical circuit information registered in the piping instrumentation diagram database as a key, and to link the alarm information in interlock block diagrams registered in the other databases using the alarm information registered in the piping instrumentation diagram database as a key. [Effects of the Invention]

[0014] According to embodiments of the present invention, when planning tests for a nuclear power plant, users can access the page containing the necessary information in the latest reference book in the shortest possible time. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0016] Hereinafter, embodiments of the test work support system and the test work support method will be described in detail with reference to the drawings.

[0017] Reference numeral 1 in FIG. 1 is the test work support system of the present embodiment. The test work support method is implemented using this test work support system 1. The test work support system 1 is a system for assisting in the investigation of related documents during the test plan and test, and for assisting in the transfer management and work progress management of the test target equipment. For example, the test work support system 1 assists in the test planning work and the test progress management work in the flow path confirmation test and the interlock test of a nuclear power plant. Note that the work includes its preparation.

[0018] The test work support system 1 includes a plurality of work support terminals 2, a database group 10, and a design drawing data server 16.

[0019] The test work support system 1 is a computer equipped with hardware resources such as a CPU (Central Processing Unit), GPU (Graphics Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), HDD (Hard Disk Drive), and SSD (Solid State Drive), and the CPU executes various programs, thereby enabling software-based information processing using the hardware resources. Furthermore, the test work support method of this embodiment is implemented by having the computer execute various programs.

[0020] Each component of the Test Work Support System 1 does not necessarily have to be installed on a single computer. For example, one Test Work Support System 1 may be implemented using multiple computers connected to each other via a network. For example, a single database configuration may be installed on each individual computer.

[0021] The configuration of the test work support system 1 may be implemented as a cloud service. In other words, the computers that make up the test work support system 1 may be servers on the cloud. For example, not only the configuration that processes memory, but the entire configuration that processes the main processing may reside on the cloud, and the user may only configure the test work support system 1 and check the input / output via an API (Application Programming Interface) or a web browser.

[0022] The database group 10 includes a piping and instrumentation diagram database 11, a deployment and connection diagram database 12, an interlock block diagram database 13, a 3D CAD database 14, and an equipment layout diagram database 15. These are one or more other databases (other databases) in this embodiment. Hereinafter, the piping and instrumentation diagram may be referred to as P&ID, the deployment and connection diagram as ECWD, and the interlock block diagram as IBD.

[0023] The database group 10 and the design drawing data server 16 are collections of information that are stored in hardware resources such as memory, HDDs, SSDs, or cloud computing resources, and are organized so that they can be searched or stored.

[0024] Multiple work support terminals 2 are connected to the database group 10 and the design drawing data server 16 via predetermined software and a predetermined network. The predetermined network includes the Internet, LAN (Local Area Network), WAN (Wide Area Network), and mobile communication networks.

[0025] The piping and instrumentation diagram database 11 is the core of the test work support system 1. The piping and instrumentation diagram database 11 contains registered piping number information, equipment number information, electrical circuit information, and alarm information.

[0026] The piping and instrumentation diagram database 11 and the unfolded connection diagram database 12 are linked by electrical circuit information. For example, various types of information are registered in the unfolded connection diagram database 12 using electrical circuit information as the primary key.

[0027] The piping and instrumentation diagram database 11 and the interlock block diagram database 13 are linked by alarm information. For example, various types of information are registered in the interlock block diagram database 13 using alarm information as the primary key.

[0028] The piping and instrumentation diagram database 11 and the 3D CAD database 14 are linked by piping number information and equipment number information. For example, various types of information are registered in the 3D CAD database 14 using at least one of the piping number information and equipment number information as the primary key.

[0029] The piping and instrumentation diagram database 11 and the equipment layout diagram database 15 are linked by equipment number information. For example, various types of information are registered in the equipment layout diagram database 15 using the equipment number information as the primary key.

[0030] Since the database group 10 is shared with the design drawing data server 16, the latest version of the design documents can always be accessed. The scope of the work to be transferred is presented to each group via this test work support system 1.

[0031] At a nuclear power plant, multiple workers are divided into multiple groups, each responsible for a specific task. For example, the workers may be divided into a testing group, an electrical instrumentation testing group, a mechanical work group, and an electrical instrumentation work group. Each group of workers is provided with a work support terminal 2. By operating the work support terminal 2, workers can access the database group 10 and the design drawing data server 16. In particular, workers proceed with their work while viewing designated pages of drawings stored in the design drawing data server 16. This viewing allows workers to confirm piping connections, interlocks, and electrical connections.

[0032] One or more computers constituting the test work support system 1 are at least one of the computers constituting the database group 10 or the work support terminal 2. This computer uses the piping number information and equipment number information in the piping and instrumentation diagrams registered in the piping and instrumentation diagram database 11 as keys to link to the piping number information and equipment number information in the 3D CAD drawings registered in the 3D CAD database 14. This computer also uses the equipment number information registered in the piping and instrumentation diagram database 11 as keys to link to the equipment number information in the equipment layout diagram 25 (Figure 6) registered in the equipment layout diagram database 15. This computer also uses the electrical circuit information registered in the piping and instrumentation diagram database 11 as keys to link to the electrical circuit information in the deployed connection diagrams registered in the deployed connection diagram database 12. This computer also uses the alarm information registered in the piping and instrumentation diagram database 11 as keys to link to the alarm information in the interlock block diagrams registered in the interlock block diagram database 13.

[0033] The work support terminal 2 may also perform a process to link the piping and instrumentation diagram database 11 with other databases.

[0034] As shown in Figure 2, the work support terminal 2 comprises an input unit 3, an output unit 4, a communication unit 5, a processing circuit 6, and a storage unit 7.

[0035] Input unit 3 receives predetermined information in response to the user's operations using the work support terminal 2. This input unit 3 includes input devices such as a mouse, keyboard, and touch panel. In other words, predetermined information is input to the test work support system 1 in response to the operation of these input devices.

[0036] Output unit 4 outputs predetermined information. The work support terminal 2 includes a device for displaying images, such as a display that outputs the analysis results. In other words, output unit 4 controls the images displayed on the display. The display may be separate from the computer main unit or integrated into it.

[0037] In this embodiment, a display is exemplified as a device for displaying images, but other embodiments are also possible. For example, images may be displayed using a head-mounted display or a projector. Furthermore, a printer that prints information on paper may be used instead of a display. In other words, the objects controlled by the output unit 4 may include a head-mounted display, a projector, or a printer.

[0038] The communication unit 5 communicates with other computers via a communication line such as the Internet. In this embodiment, the work support terminal 2 and other computers are connected to each other via the Internet, but other configurations are also possible. For example, the work support terminal 2 and other computers may be connected to each other via a LAN (Local Area Network), WAN (Wide Area Network), or mobile communication network. Alternatively, each device may be connected to each other via a bus.

[0039] The processing circuit 6 is, for example, a circuit equipped with a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or a dedicated or general-purpose processor. This processor realizes various functions by executing various programs stored in the memory unit 7. The processing circuit 6 may also be composed of hardware such as an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). Various functions can also be realized by this hardware. Furthermore, the processing circuit 6 can realize various functions by combining software processing by the processor and programs with hardware processing.

[0040] The storage unit 7 stores various types of information necessary for providing test work support based on the information stored in each of the database groups 10 and the design drawing data server 16. For example, the storage unit 7 stores a predetermined program to be executed by the processing circuit 6.

[0041] As shown in Figure 1, piping number information, equipment number information, electrical circuit information, and alarm information are pre-extracted from the drawings stored in the design drawing data server 16 and are pre-linked to the page of the drawing from which the information was extracted.

[0042] One or more computers constituting the test work support system 1 access and display pages of drawings stored in the design drawing data server 16 based on links to each database.

[0043] Since the piping and instrumentation diagram database 11 and the unfolded connection diagram database 12 are linked by electrical circuit information, the unfolded connection diagram database 12 can be accessed from the piping and instrumentation diagram database 11.

[0044] The piping and instrumentation diagram database 11 and the interlock block diagram database 13 are linked by alarm information, so the interlock block diagram database 13 can be accessed from the piping and instrumentation diagram database 11.

[0045] The piping and instrumentation diagram database 11 and the 3D CAD database 14 are linked by piping number information and equipment number information, so the 3D CAD database 14 can be accessed from the piping and instrumentation diagram database 11.

[0046] The piping and instrumentation diagram database 11 and the equipment layout diagram database 15 are linked by equipment number information, so the equipment layout diagram database 15 can be accessed from the piping and instrumentation diagram database 11.

[0047] Since the latest versions of the documents are always uploaded to the database group 10 and the design drawing data server 16, users can access the page containing the necessary information for the latest documents to be checked in the shortest possible time when planning tests.

[0048] One or more computers constituting the test work support system 1 accept user input when the user formulates a test schedule and creates a test plan, allowing the user to select target equipment from the scope of the test. This computer accesses and displays the page containing the information to be provided to the user in the latest documents registered in the database group 10 and the design drawing data server 16. Here, the latest documents registered in the database group 10 and the design drawing data server 16 are linked to piping number information, equipment number information, electrical circuit information, and alarm information registered in the piping and instrumentation diagram database 11.

[0049] As shown in Figure 3, the screen of the work support terminal 2 displays the P&ID diagram (piping and instrumentation diagram) 20 registered in the piping and instrumentation diagram database 11.

[0050] The user selects the test flow path range in the P&ID drawing (piping and instrumentation diagram) 20 using the mouse pointer 21. The work support terminal 2 then displays the range selected by the user, filled with a predetermined color (first color). Furthermore, the work support terminal 2 displays the menu bar 22. Here, the work support terminal 2 displays the name of the drawing document related to the range selected by the user in the P&ID drawing (piping and instrumentation diagram) 20, the test completion status, the transfer target list, and the menu bar 22 that allows access to 3D CAD.

[0051] For example, the work support terminal 2 displays the test channel range in a predetermined color when the user selects the test channel range in the P&ID drawing (piping and instrumentation diagram) 20. The work support terminal 2 can then access drawings related to the target range in this P&ID drawing (piping and instrumentation diagram) 20.

[0052] The displayed menu bar 22 consists of selection items related to the range selected by the user in the P&ID drawing (piping and instrumentation diagram) 20. For example, menu bar 22 consists of selection items such as IBD, ECWD, 3DCAD, test completion, transfer target list, and equipment layout. In addition, drawing document names may also be included in menu bar 22. When the user selects any selection item, drawing information related to the selected range is displayed on the screen of the work support terminal 2.

[0053] Furthermore, if the screen of the work support terminal 2 is a touch panel, the user may select a predetermined area in the drawing using touch operation instead of the mouse pointer 21.

[0054] As shown in Figure 4, the user selects the "IBD" item in the menu bar 22 using the mouse pointer 21. The work support terminal 2 then identifies the equipment related to the user's selected area in the P&ID diagram (piping and instrumentation diagram) 20 from the alarm information (IBD information) linked to the piping and instrumentation diagram database 11. Next, the work support terminal 2 displays an IBD diagram (interlock block diagram) 23 with the portion related to the alarm information of the identified equipment filled in. In this way, the user can easily obtain alarm information related to the test.

[0055] As shown in Figure 5, the user selects the "ECWD" item in the menu bar 22 using the mouse pointer 21. The work support terminal 2 then identifies the equipment related to the user's selected area in the P&ID drawing (piping and instrumentation diagram) 20 from the electrical circuit information (ECWD information) linked to the piping and instrumentation diagram database 11. Next, the work support terminal 2 displays an ECWD drawing (deployed connection diagram) 24 with the electrical circuits of the identified equipment filled in. In this way, the user can easily obtain the electrical circuit information related to the test.

[0056] As shown in Figure 6, the user selects the "Equipment Layout" item in the menu bar 22 using the mouse pointer 21. The work support terminal 2 then identifies the equipment related to the user's selected area in the P&ID drawing (piping and instrumentation diagram) 20 from the equipment number information linked to the piping and instrumentation diagram database 11. Next, the work support terminal 2 displays an equipment layout diagram 25 with the area where this identified equipment is located filled in. In this way, the user can easily obtain information about the area where the test will be performed.

[0057] As shown in Figure 7, the user selects the "3DCAD" item in the menu bar 22 using the mouse pointer 21. The work support terminal 2 then identifies the equipment related to the user's selected area in the P&ID drawing (piping and instrumentation diagram) 20 from the piping number information and equipment number information linked to the piping and instrumentation diagram database 11. Next, the work support terminal 2 displays a 3DCAD drawing 26 with the installation location of this identified equipment filled in. In this way, the user can confirm the installation location of the equipment during the line check of the equipment to be tested, which is performed before the test.

[0058] As shown in Figure 8, the user selects the "Transfer Target List" item in the menu bar 22 using the mouse pointer 21. The work support terminal 2 then identifies the equipment located within the equipment transfer range requested for each group responsible for the work related to the range selected by the user in the P&ID drawing (piping and instrumentation diagram) 20. Next, the work support terminal 2 displays a predetermined list (transfer target list) 27 of this identified equipment. In this way, communication of transfer locations can be eliminated, and the user can manage whether or not the equipment has been transferred before the test. Furthermore, since the equipment transfer range requested for each group can be shared among users using the piping and instrumentation diagram, interlock block diagram, and deployment connection diagram, discrepancies in the transfer target range can be eliminated, and the understanding of the transfer range and the request date can be shared.

[0059] As shown in Figure 9, the user selects the "Test Complete" item in the menu bar 22 using the mouse pointer 21. When the user enters the test result indicating test completion, the work support terminal 2 fills the test completion area 28 in the P&ID diagram (piping and instrumentation diagram) 20 and the IBD diagram (interlock block diagram) 23 with a predetermined color (second color) and displays this test completion area 28. The work support terminal 2 fills the test completion area 28 with a different color (second color) than the color (first color) used when the user selected the test flow path area. In this way, the test completion area 28 is automatically filled in, making it easier for the user to recognize that the test is complete.

[0060] The aforementioned test work support system 1 comprises a control device, a memory device, an output device, an input device, and a communication interface. Here, the control device includes a highly integrated processor such as a CPU (Central Processing Unit), GPU (Graphics Processing Unit), FPGA (Field Programmable Gate Array), or a dedicated chip. The memory device includes ROM (Read Only Memory), RAM (Random Access Memory), HDD (Hard Disk Drive), SSD (Solid State Drive), etc. The output device includes a display panel, a head-mounted display, a projector, a printer, etc. The input device includes a mouse, a keyboard, a touch panel, etc. This test work support system 1 can be implemented with a hardware configuration using a standard computer.

[0061] The program executed by the aforementioned test work support system 1 is provided pre-installed on ROM or similar media. Alternatively, this program may be provided as an installable or executable file stored on a computer-readable, non-temporary storage medium. This storage medium may include CD-ROMs, CD-Rs, memory cards, DVDs, flexible disks (FDs), etc.

[0062] Furthermore, the program executed by this test work support system 1 may be stored on a computer connected to a network such as the Internet and provided via download over the network. In other words, the program may be provided from cloud computing resources. Alternatively, a server on the cloud may execute the program, and only the processing results may be provided via the cloud. In addition, this test work support system 1 can also be configured by connecting and combining separate modules, each independently performing the functions of its components, via a network or dedicated line.

[0063] According to the embodiment described above, the computer uses the piping number information and equipment number information as keys to link to the piping number information and equipment number information in 3D CAD drawings registered in one or more other databases. This allows the user to quickly access the page containing the necessary information in the latest documents that need to be checked when planning tests for a nuclear power plant.

[0064] When planning tests for nuclear power plants, users can access the necessary information in the latest documents in the shortest possible time, thus reducing both work time and the amount of materials involved.

[0065] Furthermore, since the scope of equipment transfer requested for each group can be shared using piping and instrumentation diagrams, interlock block diagrams, and deployment connection diagrams, discrepancies in the scope of transfer can be eliminated, ensuring shared understanding of the transfer scope and request date, and preventing omissions in the transfer locations.

[0066] Furthermore, because users can easily confirm the placement of equipment, it can be used as an auxiliary tool for coordinating work areas with other tasks, thereby eliminating process delays caused by interference between work areas.

[0067] Furthermore, during the line check of the equipment to be tested before the test, the user can confirm the installation location of the equipment, allowing for more efficient verification work and reducing working time.

[0068] Furthermore, when a user inputs test results, the completed test area 28 is automatically filled in on the piping and instrumentation diagram, interlock block diagram, and deployment connection diagram, allowing other users to visually understand the test progress. This enables efficient management of test progress.

[0069] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These embodiments can be carried out in a variety of other forms, and various omissions, substitutions, modifications, and combinations are possible without departing from the spirit of the invention. These embodiments or their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents. Where there is a singular noun, it does not exclude plural nouns unless the context clearly indicates otherwise. Furthermore, conjunctions such as "and" and "or" are inclusive unless the context clearly indicates otherwise. [Explanation of Symbols]
