[DESCRIPTION]

[Title of Invention]

PLANT OPERATION TRAINING SIMULATOR SYSTEM AND METHOD

[Technical Field]

[0001] The present invention relates to a plant operation training simulator system and method, and in particular can be suitably applied to a plant operation training simulator system and method in which a plurality of servers used in a practical plant are integrated into a single server.

[Background Art]

[0002] Generally speaking, the scale of practical plants such as an atomic power plant is enormous, and upon controlling the operation of a practical plant, the operator operates the operation monitor control panel provided in the central control room.

Nevertheless, it is not as though the practical plant can be operated for skill training.

Thus, in the foregoing case, a plant operation training simulator system is used.

[0003] A plant operation training simulator system is a system in which a practical plant is virtually built, and is a system which simulates the operation of the practical plant based on the operation of programs. When the operator operates this plant operation training simulator system, the operator can confirm the same behavior as that of a practical plant.

[0004] Meanwhile, among the various practical plants, an Advanced BWR (ABWR), which is an improved version of a Boiling Water Reactor (BWR), uses numerous GUIs (Graphical User Interfaces), and the various equipment in the plant, which are monitored and displayed on FDs (Flat Displays), can be easily operated.

[0005] With a plant operation training simulator system of an Advanced BWR, by operating the various equipment in the plant which are monitored and displayed on the FDs based on touch operation or the like, the various equipment that was subject to the touch operation can also be operated in the same manner as a practical plant.

[0006] A plant operation training simulator of an Advanced BWR is configured by comprising a plurality of FDs, and each FD belongs to one system among the plurality of systems configuring the plant. A system is a unit of an independent network. The EDs and the various equipment in the plant are divided for each system, and the range that is displayed in an operable manner on the FD differs for each system to which the FD belongs.

[0007] When the various equipment in the plant that are being monitored and displayed on the FD are operated, for instance, based on a touch operation, an operation request is sent to an HMI (Human Machine Interface) server corresponding to the system to which the FD belongs. And after the HMI server executes the processing corresponding to the operation request, by sending the processing result to the ED, various services are provided in response to the operation from the FD.

[0008] PTL 1 discloses a configuration of a practical plant in which the HMI server is disposed for each system. Specifically, PTL discloses a client server-type plant operation monitoring apparatus comprising, in a plant configured from a plurality of systems, a ED which is provided for each of a plurality of systems, a client which is provided for each of the plurality of systems and processes an operation monitoring request, and a plurality of HMI servers which provide services to requests from the client.

[Summary of Invention]

[Technical Problem] [0010] Nevertheless, with the apparatus described in PTL 1, since each system is configured from one or two HMI servers and a plurality of FDs, when the number of FDs relative to the HMI servers of the respective system is n and the number of systems of the overall apparatus is m, the number of HMI servers of the overall apparatus will be (mi-a) and the number of FDs of the overall apparatus will be (m+a)xn, and enormous hardware resources are required.

[0011] And if the configuration of this practical plant is applied as is to a plant operation training simulator system, enormous hardware resources will become required as with the practical plant, and immense costs are required even though it is merely a simulator to be used for operation training.

[0012] The present invention was devised in view of the foregoing points, and an aim of this invention is to propose an operation training simulator system and method capable of reducing costs.

[Solution to Problem] [0013] In view of the foregoing aim, the present invention proposes a plant operation training simulator system which simulates behavior of a plant configured from a plurality of systems comprising a plurality of ED clients for displaying equipment installed in each of the plurality of systems in a manner such that the equipment can be operated with respect to each system, and a single integrated server internally comprising a plurality of physical servers for managing, with respect to each system, the equipment installed in each of the plurality of systems, wherein, upon receiving an operation request of the equipment, the FD client stores the operation request and information for determining the system in a transmission header file, and sends the transmission header file to the integrated server, and, wherein, upon receiving the transmission header file, the integrated server determines the ED client as a source of the transmission header file based on the information for determining the system, and sends the operation request to the physical server managing the equipment that is displayed as being operable by the determined ED client.

[0014] Moreover, in view of the foregoing aim, the present invention proposes a plant operation training simulator method which simulates behavior of a plant configured from a plurality of systems comprising a first step of a plurality of FD clients displaying equipment installed in each of the plurality of systems in a manner such that the equipment can be operated with respect to each system, a second step of a single integrated server internally comprising a plurality of physical servers managing, with respect to each system, the equipment installed in each of the plurality of systems, a third step of the FD client storing, upon receiving an operation request of the equipment, the operation request and information for determining the system in a transmission header file, and sending the transmission header file to the integrated server, and a fourth step of the integrated server determining, upon receiving the transmission header file, the FD client as a source of the transmission header file based on the information for determining the system, and sending the operation request to the physical server managing the equipment that is displayed as being operable by the determined FD client.

[Advantageous Effects of Invention] [0015] According to the present invention, it is possible to reduce costs for virtually building a practical plant.

[Description of Embodiments]

[0017] An embodiment of the present invention is now explained in detail with reference to the appended drawings.

[0018] (1) Overall configuration Fig. 1 is an overall configuration diagram of the plant operation training simulator system 1 according to this embodiment. The plant operation training simulator system 1 is configured by comprising a simulation server 11, an integrated HMI (Human Machine Interface) server 12, a plurality of FD (Flat Display) clients 13, and a plurality of instructor clients 14.

[0019] The simulation server 11, the integrated HMI server 12, the plurality of FD clients 13 and the plurality of instructor clients 14 are mutually connected in a communicable manner via a communication interface IF.

[0020] Note that, in the ensuing explanation] when an explanation is provided with reference to "FD client 13", the explanation relates to the FD clients as a whole without differentiating the FD clients 1 3A to 1 3E. When it is necessary to differentiate the FD clients, an indication of "FD client 1 3A" or the like will be used in the explanation. The same applies to the FD 131 and the control unit 132. The same also applies to the "instructor client 14".

[0021] When the simulation server 11 receives a simulation execution request from the integrated HMI server 12, the simulation server 11 executes arithmetic processing corresponding to the execution request. The simulation server 11 thereby simulates the operation of the plant by sending, to the integrated HMI server 12. the arithmetic result obtained as a result of executing the arithmetic processing.

[0022] When the integrated HMI server 12 receives an operation request from the FD client 13, the integrated HMI server 12 determines which FD client 13 among the FD clients 13A to 13E sent the operation request. Here, let it be assumed that the data required for the service to be provided to the determined ED client 13 has be acquired from a process computer server not shown and stored in the integrated HMI server 12 in advance.

[0023] A process computer server is a terminal for monitoring the flow rate: pressure and other statuses of the plurality of equipment installed in the plant. The integrated HMI server 12 sends, to the simulation server 11, the simulation execution request together with the data concerning the status of various equipment which has been acquired from the process computer server and stored in the integrated HMI server 12 in advance.

[0024] When the integrated HMI server 12 receives the arithmetic result sent from the simulation server 11, the integrated HMI server 12 provides the service for each system by sending the receiving arithmetic result to the FD client 13. A system refers to the range within the plant in which each of the plurality of ED clients 13A to 13E can be operated.

[0025] Here, for example, the various equipment in the plant that can be operated by the ED client 13A and the various equipment in the plant that can be operated by the ED client 13B are different. Note that the integrated HMI server 12 also receives operation requests from the instructor client 14 without limitation to the FD client 13.

[0026] The instructor client 14 is a terminal capable of operating a plurality of systems as described later. In the foregoing case, foremost, the integrated HMI server 12 determines the intended system of the operation request from the instructor client 14 (that is, for which system the operation request was sent). After the system is determined, the foregoing processing is executed to the target system and the service is provided for each system.

[0027] The FD client 13 is configured by comprising an FD 131 and a control unit 132. The FD 131 is, for example, a touch panel, and displays screen data generated by the control unit 132 on a display screen in an operable manner. When a touch operation is performed to the display screen based on the user's operation, the FD 131 sends, to the control unit 132, an operation request of the equipment of the position where the touch operation was performed.

[0028] The control unit 132 is configured by comprising a CPU (Central Processing Unit), a memory and the like, and a screen display program is stored in the memory. The CPU generates screen data by coordinating with the screen display program, and sends the generated screen data to the FD 131. Moreover, when the control unit 132 receives an operation request from the ED 131, the control unit 132 sends the operation request to the integrated HMI server 12.

[0029] When the control unit 132 receives the arithmetic result corresponding to the operation request from the integrated HMI server 12, the control unit 132 generates new screen data based on the arithmetic result, replaces the existing screen data with the generated new screen data, sends the new screen data to the FD 131, and thereby updates the display screen displayed on the ED 131.

[0030] Note that the FD client 13 displays on the display screen only information of the equipment belonging to the system in which each of the ED clients 13A to 13E is in charge. Thus, for instance, the display screen displayed by the ED 131A and the display screen displayed by the FD 131B are different. Meanwhile, the instructor client 14 displays a display screen related to information of a plurality of systems, and the instructor client 14 differs from the FD client 13 with respect to this point.

[0031] The instructor client 14 is configured by comprising a common simulator control screen 141 and a control unit 142. The common simulator control screen 141 is similar to the ED 131 with respect to the point that it displays screen data on the display screen in an operable manner, but differs from the ED 131, which displays only information of a single system, with respect to the point that it displays information of a plurality of systems in an operable manner.

[0032] Moreover, the control unit 142 is configured by comprising a CPU, a memory and the like, and a screen display program is stored in the memory as with the control unit 132. The control unit 142 differs from the control unit 132, which generates only / screen data of a single system, with respect to the point that it generates a plurality of screen data.

[0033] (2) Functional configuration Fig. 2 shows a functional configuration of the plant operation training simulator system 1. Here, the functional configuration of the integrated HMI server 12 and the FD clients 13A and i3B which display information for each system, in an operable manner, based on a port number is particularly explained.

[0034] In addition to comprising a CPU and a memory (not shown), the integrated HMI server 12 is configured by comprising a communication interface 121, an interface program 122 and an actual equipment HMI server 123. Note that the interface program 122, the actual equipment HMI server 123 and the port number management table Ti described later may also be stored in the memory (not shown).

[0035] The communication interface 121 is an interface for receiving a transmission header file Di from either client 13A or 13B and sending the received transmission header file Dl to the interface program 122, and sending the arithmetic result from the interface program 122 to either client 13A or 13B.

[0036] The transmission header file Dl is configured, as shown in the diagram, a header information region, a data information region, a port number region and a backup region. Here, the interface program 122 determines, based on the port number stored in the pod number region, whether the transmission header file Dl is the transmission header file Dl that was sent from the FD client 13A or the transmission header file Dl that was sent from the ED client 1 3B.

[0037] When the interface program 122 receives the transmission header file Dl sent from the communication interface 121, the interface program 122 extracts the port number from the transmission header file Dl, refers to the port number management table Ti, and identifies the actual equipment HMI server 123 that is associated with the extracted port number. Here, one server among the servers A to C is identified.

[0038]

S

The port number management table Ti is a table for associating the port numbers of the source and the plurality of servers within the actual equipment HMI server 123 and managing such association. By referring to the port number management table Ti, for instance, the interface program 122 can send the transmission header file Di to the server A among the servers A to C when the transmission header file Dl is sent from the FD client i 3A.

[0039] The actual equipment HMI server i23 is configured by comprising a plurality of servers that are logically divided for each system. Here, the plurality of servers are logically divided in the actual equipment HMI server 123 so that the server A belongs to the same system as the FD client i3A, and the server B belongs to the same system as the ED client i3B. Each of the servers A to C is configured by comprising the same program and data corresponding to the affiliated system based on the same structure.

[0040] The plurality of servers A to C configuring the actual equipment HMI server are installed by being separated physically, and in terms of network, in the actual practical plant, but here, are integrated in the integrated HMI server 12. Since the servers A to C are configured based on the same data structure, when these are integrated, it will not be possible to identify the server to which the transmission header file Di should be sent. Here, however, the server to which the transmission header file Di should be sent can be identified based on the port number.

[0041] For example, the server A to which the transmission header file Di was sent based on the port number will send a simulation execution request to the simulation server ii based on the received transmission header file Dl.

[0042] Subsequently, when the server A receives the arithmetic result in response to the execution request from the simulation server ii, the server A sends the received arithmetic result to the interface program 122. When the interface program 122 receives the arithmetic result, the interface program 122 sends the received arithmetic result to the FD client i3, which is the source of the transmission header file Dl.

[0043] In addition to comprising the FD 131A and the control unit 132A described above with reference to Fig. 1, the FD client 13A is configured by comprising a communication interface 133A and a server A communication interface 134A. The FD client 1 3B differs from the FD client 1 3A with respect to the point that it comprises a server B communication interface 134B, but is otherwise configured the same as the FD client 13A.

[0044] The communication interface 133A is an interface for sending and receiving data between the FD 131A and the control unit 132A. The server A communication interface 134A is an interface for sending and receiving data between the FD client 13A and the integrated HMI server 12.

[0045] The server A communication interface 134A of the FD client 13A and the server B communication interface 134B of the ED client 13B are different interfaces, and, for instance, have different port numbers. Thus, the port number stored in the port number region of the transmission header file Dl sent from the FD client 1 3A and the port number stored in the port number region of the transmission header file Dl sent from the ED client 1 3B are different.

[0046] The control unit 132A stores the pod number of the server A communication interface 134A in the port number region of the transmission header file Dl, and thereafter sends the transmission header file Dl to the integrated HMI server 12. Meanwhile, the control unit 132A is configured by comprising a screen display program 1321A and a screen data 1 322A.

[0047] When the screen display program 1321A receives the arithmetic result from the integrated HMI server 12, the screen display program 1321A generates new screen data 1 322A and replaces existing screen data 1 322A with the generated new screen data 1322A. Subsequently, the screen display program 1321A sends the new screen data 1322A to the FD 131A. The FD 131A switches the existing display screen, and displays the new display screen in an operable manner.

[0048] Fig. 3 shows a functional configuration of another plant operation training simulator system 1A. Here, the functional configuration of the integrated HMI server 12 and the FD clients 13A and 13B which display information for each system, in an operable manner, based on a server number is particularly explained.

[0049] Note that the configuration that is the same as the plant operation training simulator system 1 of Fig. 2 is given the same reference numeral and the explanation thereof is omitted, and only the different configurations are explained.

[0050] The plant operation training simulator system 1A of Fig. 3 differs from the plant operation training simulator system 1 with respect to the following points; namely, server numbers 1323A and 1323B are assigned to the respective screen data 1322A and 1322B, the respective client FDs 13A and 13B comprise the same interface; specifically, a common communication interface 134, a server number region for storing the server number is included in the transmission header file Dii, and the integrated HMI server 12 comprises a server number management table Ti 1.

[0051] In the plant operation training simulator system iA of Fig. 3, for instance, when the screen display program i32iA receives an operation request from the FD i3iA, the screen display program i32iA stores the server number i323A in the server number region of the transmission header file Dii, and sends the transmission header file Dii to the integrated HMI server 12.

[0052] The interface program 122 of the integrated HMI server 12 refers to the server number i323A of the source and the server number management table Til that is associated with the server A, and sends the received transmission header file Dii to the server A. Subsequently, when the interface program 122 receives an arithmetic result from the server A, the interface program 122 sends the received arithmetic result to the FD client 1 3A.

[0053] When the screen display program i32iA receives the arithmetic result from the integrated HMI server 12, the screen display program i32iA generates new screen data i322A, and replaces existing screen data i322A. Subsequently, the screen display program 1321A sends the new screen data 1322A to the ED 131A. The ED 131A switches the existing display screen and displays the new display screen.

[0054] Fig. 4 shows the functional configuration of the plant operation training simulator system 1A of Fig. 3. Here, the functional configuration of the integrated HMI server 12 and the instructor client 14A which display information for each system, in an operable manner, based on a server number is particularly explained.

[0055] In the plant operation training simulator system 1A of Fig. 4, for instance, when the screen display program 1421A of the instructor client 14A receives an operation request including a designation of the screen data 1 322A from the common simulator control screen 141A, the screen display program 1421A stores the server number 1323A in the server number region of the transmission header file Dli, and sends the transmission header file Dli to the integrated HMI server 12.

[0056] The interface program 122 of the integrated HMI server 12 refers to the server number management table Ti 1, and sends the received transmission header file Dli to the server A. Subsequently, when the interface program 122 receives an arithmetic result from the server A, the interface program 122 sends the received arithmetic result to the instructor client 14A.

[0057] When the screen display program 1421A receives the arithmetic result from the integrated HMI server 12, the screen display program 1421A generates new screen data 1322A, and replaces existing screen data 1322A with the new screen data 1322A. Subsequently, the screen display program 1421A sends the new screen data i322A to the common simulator control screen l4iA. The common simulator control screen 141A switches the existing display screen and displays the new display screen.

[0058] Fig. 5 shows a functional configuration of another plant operation training simulator system lB. Here, the functional configuration of the integrated HMI server 12, the FD client 13A and the instructor client i4A which display information for each system, in an operable manner, based on a server number is particularly explained.

[0059] Note that the configuration that is the same as the plant operation training simulator system 1A of Fig. 3 and Fig. 4 is given the same reference numeral and the explanation thereof is omitted, and only the different configurations are explained.

[0060] The plant operation training simulator system 1 B of Fig. 5 differs from the plant operation training simulator system 1A of Fig. 3 and Fig. 4 with respect to the following points; namely, the integrated HMI server 12 comprises a common program 124 in substitute for the interface program 122, and the respective servers A to C only comprise data without comprising programs.

[0061] The ED client 13A or the instructor client 14A sends, to the integrated HMI server 12, the transmission header file Dli storing the server number. Thus, the integrated HMI server 12 can determine which of the servers A to C should be accessed by referring to the server number management table Ti 1.

[0062] Thus, here, a common program 124 which commonalizes the respective programs of the respective servers A to C of the actual equipment HMI server 123 as one common program is provided, and the common program 124 displays information for each system, in an operable manner, based on the server number.

[0063] (3) Flowchart Fig. 6 shows the processing routine of the screen display processing in a case where the integrated HMI server 12 comprises the interface program 122. Here, the screen display processing is executed by the FD client 13A, the integrated HMI server 12 and the simulation server 11 of the plant operation training simulator system 1. The processing executed by the ED client 13A may also be executed, for instance, by the FD client 13B or the instructor client 14.

[0064] Foremost, when the screen display program 1321A of the ED client 13A receives an equipment operation request from the FD 131A (SF1), the screen display program 1321A writes the operation request, together with the pod number, into the transmission header file Dl, and sends the transmission header file Dl to the interface program 122 (SF2).

[0065] Subsequently, when the interface program 122 of the integrated HMI server 12 receives the transmission header file Dl, the interface program 122 refers to the port number management table Ti, and identifies the actual equipment HMI server 123 (one server among the servers A to C) belonging to the same system as the FD client 13A that sent the transmission headerfile Dl (SF3).

[0066] Subsequently, the interface program 122 sends the transmission header file Dl to the actual equipment HMI server 123 identified in step SP3 (here, let it be assumed that the server A has been identified) (SF4).

[0067] When the program of the server A within the actual equipment HMI server 123 receives the transmission header file Dl, it identifies the equipment to be operated (SF5), and sends a simulation execution request regarding the identified equipment to the simulation server 11 (SF6).

[0068] When the simulation server 11 receives the simulation execution request, the simulation server 11 executes arithmetic processing (SF7), and obtains an arithmetic result. Subsequently, the simulation server 11 sends the obtained arithmetic result to the server A within the actual equipment HMI server 123 (SF8).

[0069] When the program of the server A within the actual equipment HMI server 123 receives the arithmetic result, it stores the received arithmetic result as data in the server A(5P9), and sends the arithmetic result to the interface program 122 (SF10).

[0070] When the interface program 122 receives the arithmetic result, the interface program 122 converts the arithmetic result into the transmission header file Dl to be used for communicating with the ED client 13A (SF11), and sends the transmission header file Dl to the screen display program 1321A (SF12).

[0071] When the screen display program 1321A receives the transmission header file Dl, the screen display program 1321A generates screen data based on the transmission header file Dl (SF13). Subsequently, the screen display program 1321A sends the generated screen data to the FD 131A (SF14), and then ends the screen display processing.

[0072] Subsequently, the FD 131A displays the screen data from the screen display program 1321A on the display screen.

[0073] The processing explained with reference to Fig. 6 is similarly executed in the plant operation training simulator system 1A. In the foregoing case, in step SF2, the screen display program 1321A writes the operation request, together with the server number, into the transmission header file Dli.

[0074] Moreover, in step SF3, the interface program 122 refers to the server number management table Til, and identifies the actual equipment HMI server 123 belonging to the same system as the FD client 1 3A that sent the transmission header file Dli.

[0075] Fig. 7 shows the processing routine of the screen display processing in a case where the integrated HMI server 12 comprises a common program 124. This screen display processing is executed by the FD client 13A, the integrated HMI server 12 and the simulation server 11 of the plant operation training simulator system 1 B. Note that the processing executed by the FD client 13A may also be executed, for instance, by the FD client 13B or the instructor client 14.

[0076] Foremost, when the screen display program 1321A of the FD client 13A receives an equipment operation request from the FD 131A (SF21), the screen display program 1321A writes the operation request, together with the server number, into the transmission header file Dii, and sends the transmission header file Dii to the common program 124 (SF22).

[0077] Subsequently, when the common program 124 of the integrated HMI server 12 receives the transmission header file Dii, the common program 124 refers to the server number management table Iii, and identifies the actual equipment HMI server 123 (one server among the servers A to C) belonging to the same system as the FD client 13A that sent the transmission header file Dli (SF23).

[0078] Moreover, the common program 124 identifies the equipment to be operated (SF24).

Subsequently, the common program 124 sends a simulation execution request regarding the equipment identified in step SF24 to the simulation server 11 (SF25).

[0079] When the simulation server 11 receives the simulation execution request, the simulation server 11 executes arithmetic processing (SF26), and obtains an arithmetic result. Subsequently, the simulation server 11 sends the obtained arithmetic result to the common program 124 (SF27).

[0080] When the common program 124 receives the arithmetic result, the common program 124 stores the received arithmetic result as data in the server A (SF28), converts the arithmetic result into the transmission header file Dli to be used for communicating with the FD client 13A (SF29), and sends the transmission header file Dli to the screen display program 1321A (SF30).

[0081] When the screen display program 1321 A receives the transmission header file Dli, the screen display program 1321A generates screen data based on the transmission header file Dli (SF31). Subsequently, the screen display program 1321A sends the generated screen data to the FD 131A (SF32), and then ends the screen display processing.

[0082] (4) Effects yielded by this Embodiment According to the plant operation training simulator system 1 described in the foregoing embodiment, the FD client 13 or the instructor client 14 sends a transmission header file Dl including a port number to the integrated HMI server 12, and the integrated HMI server 12 determines the ED client 13 as the source of the transmission header file Dl based on the port number included in the transmission header file Dl and the port number management table Ti that is prepared in advance. Thus, even if the servers A to C for each server are collectively integrated in the integrated HMI server, it is possible to determine to which one of the servers A to C the transmission header file Di should be sent. Thus, data can be sent and received for each system without having to physically prepare a plurality of servers A to C, and the cost for building a simulator system can be reduced.

[0083] Moreover, according to the plant operation training simulator system 1A described in the foregoing embodiment, the integrated HMI server 12 determines the FD client 13 as the source of the transmission header file Dli based on the server number included in the transmission header file Dii and the server number management table Ti 1 that is prepared in advance. Thus, in addition to yielding the effect of being able to reduce costs described above, a common interface (common communication interface 134) can be used as the communication interface of the FD client 13.

[0084] Moreover, according to the plant operation training simulator system lB described in the foregoing embodiment, the integrated HMI server 12 comprises a common program 124 in substitute for the interface program 122. Thus, it is possible to yield the effect of reducing costs as described above without having to provide a program to each of the servers A to C.
