Description

[Technical Field]

[0001] The present invention relates to a production operation information communication control system, a production operation information communication control method, and a production operation information communication control program. [Background technology]

[0002] Recently, as part of economic security measures, government agencies around the world have been actively establishing security-related systems and imposing restrictions on procurement by their own government agencies. Equipment manufacturers that do not comply with these systems and standards are at risk of being excluded from the market in the future. For production sites, it is becoming an urgent task to implement secure production that takes into account security requirements such as NIST SP800-171 and UN-R155.

[0003] On the other hand, many of the current production systems used in production sites do not satisfy the above-mentioned security requirements. One example of such a production system is a system in which production work information used in production work is input and output between a terminal device used in the production work and the device to be produced via a recording medium such as a USB (Universal Serial Bus) memory. Such systems face the risk of information leakage due to the loss of the recording medium on which the production work information is stored, or the risk of tampering with production work information stored on a recording medium that has been illegally removed. Therefore, technology to resolve the security issues in production systems such as those described above is desired.

[0004] In relation to the above-mentioned technology, Patent Document 1 discloses an information transmission device including a network connection unit, a USB connection unit, and a recording medium. The network connection unit in this device connects to a communication network. The USB connection unit connects to other devices based on the USB standard. The recording medium is a volatile recording medium that stores information. This information transmission device receives information from either a device on the network connection side or a device on the USB connection side, and stores the received information in the recording medium. The information transmission device then outputs the information stored on the recording medium to the device that did not send the information, either the device on the network connection side or the device on the USB connection side.

[0005] [Patent Document 1] Japanese Patent Publication No. 2022-183888 Summary of the Invention [Problem to be solved by the invention]

[0006] A production system using the technology disclosed in Patent Document 1 is expected to resolve the security issues described above because it transmits and receives production work information between terminal devices used in production work and target devices via a communication network rather than via a storage medium such as a USB memory stick. However, a production system using the technology disclosed in Patent Document 1 has the following problems. In this production system, production work information is transmitted from a management server that centrally manages production work information to terminal devices used in production work and target devices. In this case, for example, communication congestion caused by the management server expanding the production work information may occur, which may extend the time required for each device to obtain the production information. Furthermore, if a failure occurs in the management server, each device may be unable to simultaneously obtain the production work information. In other words, a production system in which production work information is centrally managed and transmitted to each device may have the problem of reduced operational efficiency at the production site, as described above.

[0007] A primary object of the present invention is to avoid the problem of reduced work efficiency when production work information is communicated to each device at a production site. [Means for solving the problem]

[0008] A production work information communication control system according to one embodiment of the present invention comprises a plurality of terminal devices that store one or more pieces of production work information in a distributed manner, the production work information representing at least one of the specifications of a production work using one or more production target devices and information input to or output from the production target devices during the production work; an acquisition means that acquires from an external device configuration information representing the configuration of a system to which the production target devices are communicatively connected; a reception means that accepts management information representing the correspondence between the terminal devices that process each piece of production work information in response to user operation and the production target devices; and a communication means that communicates the production work information based on the configuration information between the terminal devices and the production target devices that are associated with each other in the management information.

[0009] In another aspect of achieving the above object, a production work information communication control method according to one embodiment of the present invention acquires, by an information processing device, configuration information representing the configuration of a system in which one or more terminal devices that store multiple pieces of production work information in a distributed manner and the production work information, which represent at least one of the specifications of a production work using one or more production target devices and information input to or output from the production target devices in the production work, and the production target devices are communicatively connected, from an external device, receives management information representing the correspondence between the terminal devices that process each piece of production work information in accordance with user operation and the production target devices, and communicates the production work information based on the configuration information between the terminal devices and the production target devices that are associated with each other in the management information.

[0010] In addition, in a further aspect of achieving the above-mentioned object, a production work information communication control program according to one embodiment of the present invention causes a computer to execute the following operations: an acquisition process for acquiring from an external device configuration information representing the configuration of a system to which one or more terminal devices that store multiple pieces of production work information in a distributed manner and the production work information represents at least one of the specifications of a production work using one or more production target devices and information input to or output from the production target devices in the production work; a reception process for accepting management information representing the correspondence between the terminal devices that process each piece of production work information in accordance with user operation and the production target devices; and a communication process for communicating the production work information based on the configuration information between the terminal devices and the production target devices that are associated with each other in the management information.

[0011] Furthermore, the present invention can also be realized by a computer-readable, non-volatile recording medium storing such a production operation information communication control program (computer program). [Effects of the Invention]

[0012] The present invention can avoid the problem of reduced work efficiency when production work information is communicated to each device at the production site. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0015] First Embodiment 1 is a block diagram showing the configuration of a production operation information and communication control system 1 according to the present disclosure. The production operation information and communication control system 1 is a system for carrying out production operations at a production site such as a factory. The production operation information and communication control system 1 includes a management server 10, m (m is any integer equal to or greater than 1) terminal devices 11-1 to 11-m, n (n is any integer equal to or greater than 1) production target devices 12-1 to 12-n, m communication relay devices 13-1 to 13-m, n communication relay devices 14-1 to 14-n, a management terminal device 15, an alarm indicator light 16, a communication network 17, a communication network 18, and a communication network 19.

[0016] In the following description of the present disclosure, at least one of the terminal devices 11-1 to 11-m, or all of them, may be referred to as terminal device 11. At least one of the production target devices 12-1 to 12-n, or all of them, may be referred to as production target device 12. At least one of the communication relay devices 13-1 to 13-m, or all of them, may be referred to as communication relay device 13. At least one of the communication relay devices 14-1 to 14-n, or all of them, may be referred to as communication relay device 14.

[0017] Terminal devices 11-1 to 11-m are communicably connected to communication relay devices 13-1 to 13-m, respectively, in sequence via USB, for example. Terminal device 11 and communication relay device 13 may be connected via a communication standard different from USB. Production target devices 12-1 to 12-n are communicably connected to communication relay devices 14-1 to 14-n, respectively, in sequence via USB, for example. Production target device 12 and communication relay device 14 may be connected via a communication standard different from USB.

[0018] The management server 10, communication relay devices 13-1 to 13-m, communication relay devices 14-1 to 14-n, management terminal device 15, and alarm indicator light 16 are communicatively connected via a communication network 17. Terminal devices 11-1 to 11-m are communicatively connected via a communication network 18. Production target devices 12-1 to 12-n are communicatively connected via a communication network 19. Communication network 18 and communication network 19 may be the same communication network. Furthermore, by constructing communication network 17 separately from communication networks 18 and 19, it is possible to improve security regarding the communication of production operation information 1120 and 1220 via communication network 17, which will be described later.

[0019] The terminal device 11 is an information processing device such as a personal computer that is used by a user in production work. The terminal device 11 includes a communication unit 111 and a storage unit 112. The communication unit 111 is an example of a communication means.

[0020] The storage unit 112 is, for example, a storage device such as a RAM (Random Access Memory) 903 or a hard disk 904, which will be described later with reference to FIG.

[0021] The production work information 1120 is information that represents at least one of the specifications of a production work using the production target device 12 and information that is input to or output from the production target device 12 during the production work. The production work information 1120 is, for example, information created by a user of the production work information communication control system 1. The production work information 1120 is stored in the storage unit 112, for example, via an input operation by the user on the terminal device 11. The production work information 1120 includes, for example, an inspection program executed by the production target device 12, input data that is input to the production target device 12 when the inspection program is executed, an inspection OS ( OperatingThe production work information 1120 may include image data of the production target equipment 12 (Production System). The production work information 1120 may include, for example, specifications and instructions relating to the inspection of the production target equipment 12, which are generated or updated by a user's input operation on the terminal device 11. The production work information 1120 may include information explaining the contents, such as which part of the production target equipment 12 the included specifications and instructions relate to, or which function of the production target equipment 12 the included inspection program is intended to inspect. The production work information 1120 is stored in a distributed manner on multiple terminal devices 11.

[0022] The operation of the communication unit 111 of the terminal device 11 will be described later.

[0023] The production target device 12 is the device itself that is the production target in the production work performed by the production work information and communication control system 1, or a device that is connected to the production target device and controls the inspection of the production target device. The production target device 12 is an information processing device such as a personal computer that is used by a user in the production work. The production target device 12 includes a communication unit 121 and a memory unit 122. The communication unit 121 is an example of communication means. The memory unit 122 is a memory device similar to the memory unit 112. The memory unit 122 stores production work information 1220.

[0024] Like the production work information 1120, the production work information 1220 is information used in production work, and may include, for example, information created by users of the production work information communication control system 1, and the execution results (inspection logs) of inspection programs by the production target devices 12. The production work information 1220 may also include information that explains the contents, such as which inspection program the included inspection logs are the execution results of. The production work information 1220 is stored in a distributed manner in multiple production target devices 12.

[0025] The operation of the communication unit 121 of the production target device 12 will be described later.

[0026] The communication relay devices 13 and 14 are devices that relay communication when production work information 1120 and 1220 is communicated between the terminal device 11 and the production target device 12. The communication relay device 14 also has a function to control the inspection operation by the production target device 12. For example, the communication relay device 14 may have a function as a USB memory that stores an OS image for inspection when an OS for inspection is started from a USB connected to the production target device 12.

[0027] The communication relay devices 13 and 14 may be, for example, dedicated information processing devices specialized for the communication control function of the production work information 1120 and 1220, or may be realized by general-purpose information processing devices such as personal computers. Also, the communication relay device 13 may be built into the terminal device 11, and the communication relay device 14 may be built into the production target device 12.

[0028] The management terminal device 15 is an information processing device such as a personal computer that is used by a user when inputting information to the management server 10 or when checking information output from the management server 10.

[0029] The management server 10 is an information processing device, and includes an acquisition unit 101, a reception unit 102, a detection unit 103, and a storage unit 104. The acquisition unit 101, the reception unit 102, and the detection unit 103 are examples of an acquisition means, a reception means, and a detection means, respectively.

[0030] The storage unit 104 is a storage device similar to the above-mentioned storage units 112 and 122. The storage unit 104 stores configuration information 1041, management information 1042, a master hash value 1043, and a hash value 1044. The information stored in the storage unit 104 will be described later.

[0031] The management server 10 may be a device installed at a production site or may be a device constructed as a server that provides services in a cloud computing environment. The management server 10 may also be constructed not as a standalone device but as a distributed device among the terminal device 11, production target device 12, communication relay device 13, and communication relay device 14.

[0032] The acquisition unit 101 acquires configuration information 1041 that represents the configuration of the production work information communication control system 1 in which the terminal device 11 and the production target device 12 are communicatively connected, and stores the acquired configuration information 1041 in the storage unit 104. The configuration information 1041 may be acquired, for example, from the terminal device 11, the production target device 12, the communication relay device 13, and the communication relay device 14 that are connected to the communication network 17.

[0033] The configuration information 1041 includes information that can identify each of the above-mentioned devices connected to the communication network 17. The identifiable information indicates, for example, a MAC (Media Access Control) address or an IP (Internet Protocol) address of each device connected to the communication network 17. The configuration information 1041 may also include information about the file systems of the storage unit 112 of the terminal device 11 and the storage unit 122 of the production target device 12. The information about the file systems indicates, for example, the hierarchical structure of folders constructed by the file systems.

[0034] The reception unit 102 receives management information 1042 that indicates the correspondence between the terminal device 11, which is the source or destination of communication, and the production target device 12, which is the source or destination of communication, regarding the communication of each piece of production work information 1120 and 1220. The management information 1042 is, for example, information input by a user through an input operation on the management terminal device 15.

[0035] The management information 1042 may also include information representing the communication path of the production work information 1120 from the terminal device 11 to the production target device 12, and the communication path of the production work information 1220 from the production target device 12 to the terminal device 11. For example, the communication path of the production work information 1120 communicated from the terminal device 11-1 to the production target device 12-1 is represented by the identification information of each device written in the following order: terminal device 11-1, communication relay device 13-1, communication relay device 14-1, production target device 12-1. In this case, the management information 1042 may include information capable of identifying the folder in the memory unit 112 of the terminal device 11-1 that stores the production work information 1120, and information capable of identifying the folder in the memory unit 122 of the production target device 12-1 that stores the production work information 1120.

[0036] The communication unit 111 of the terminal device 11 and the communication unit 121 of the production target device 12 communicate production work information 1120 between the terminal device 11 and the production target device 12 based on the configuration information 1041 and management information 1042 stored as described above in the storage unit 104 of the management server 10. The communication units 111 and 121 may be realized, for example, as software (agents) executed by the terminal device 11 or the production target device 12.

[0037] More specifically, the communication unit 111 reads the production work information 1120 from the folder in which the production work information 1120 is stored, which is indicated by the management information 1042, and communicates it to the communication relay device 13 included in the communication path indicated by the management information 1042. The communication relay device 13 that has received the production work information 1120 from the communication unit 111 communicates the communicated production work information 1120 to the communication relay device 14 that is included in the communication path. The communication relay device 14 that has received the production work information 1120 from the communication relay device 13 communicates the communicated production work information 1120 to the production target device 12 that is included in the communication path. The communication unit 121 of the production target device that has received the production work information 1120 from the communication relay device 14 stores the communicated production work information 1120 in the folder in the storage unit 122 that is indicated by the management information 1042 and in which the production work information 1120 is stored.

[0038] The operation of the communication unit 121 of the production target device 12 communicating production business information 1220 to the terminal device 11 via the communication relay device 14 and the communication relay device 13 is similar to the operation of the communication unit 111 described above communicating production business information 1120 to the production target device 12 via the communication relay device 13 and the communication relay device 14.

[0039] The communication units 111 and 121 may also encrypt the production work information 1120 and 1220 when communicating the production work information 1120 and 1220. However, the communication units 111 and 121 are provided with an encryption key (public key) for encrypting the production work information 1120 and 1220, and a decryption key (private key) for decrypting the encrypted production work information 1120 and 1220 that has been communicated.

[0040] In addition, when the communication unit 121 communicates the production work information 1220 including the inspection log generated by the production target device 12 from the production target device 12 to the terminal device 11, the communication unit 121 may store the communicated production work information 1220 in the production target device 12 in case the inspection log is lost.

[0041] The detection unit 103 of the management server 10 compares the production operation information 1120 and 1220 in an authenticated state with the production operation information 1120 and 1220 at a predetermined time, and if the comparison results in a discrepancy, detects that the production operation information 1120 and 1220 have been tampered with up to the predetermined time. The detection unit 103 is equipped with a clock function. The production operation information 1120 and 1220 are in an authenticated state, for example, when the production operation information 1120 is first stored in the memory unit 112 of the terminal device 11, and when the production operation information 1220 is first stored in the memory unit 122 of the production target device 12. The production operation information 1120 and 1220 are in an authenticated state, or immediately after the production operation information 1120 and 1220 are updated by a valid user input operation. The detection unit 103 may detect tampering with the production work information 1120 and 1220, for example, at predetermined time intervals.

[0042] The detection unit 103 may detect tampering with the production operation information 1120 and 1220, for example, using hash values ​​(digest values) of the production operation information 1120 and 1220. In this case, the terminal device 11 calculates a hash value of the production operation information 1120 using a predetermined hash value calculation formula when the authenticity of the production operation information 1120 is guaranteed. The terminal device 11 notifies the management server 10 of the calculated hash value as the master hash value 1043 together with information that can identify the production operation information 1120. Similarly, the production target device 12 calculates a hash value of the production operation information 1220 using a predetermined hash value calculation formula when the authenticity of the production operation information 1220 is guaranteed. The production target device 12 notifies the management server 10 of the calculated hash value as the master hash value 1043 together with information that can identify the production operation information 1220. The management server 10 stores the master hash value 1043 notified from the terminal device 11 and the production target device 12 in the storage unit 104 in association with information that can identify the production work information 1120 or 1220 .

[0043] When the time arrives to detect tampering with the production operation information 1120, the terminal device 11, in response to a request from the detection unit 103, calculates a hash value 1044 of the current production operation information 1120 using a predetermined hash value calculation formula and notifies the management server 10 of the calculated hash value 1044 together with information that can identify the production operation information 1120. Similarly, when the time arrives to detect tampering with the production operation information 1220, the production target device 12, in response to a request from the detection unit 103, calculates a hash value 1044 of the current production operation information 1220 using a predetermined hash value calculation formula and notifies the management server 10 of the calculated hash value 1044 together with information that can identify the production operation information 1220. The management server 10 stores the hash values ​​1044 notified from the terminal device 11 and the production target device 12 in the storage unit 104, in association with the information that can identify the production operation information 1120 or 1220.

[0044] The detection unit 103 compares the master hash value 1043 and the hash value 1044 for each piece of production operation information 1120 and 1220, and detects that tampering has occurred with the production operation information 1120 or 1220 for which the master hash value 1043 and the hash value 1044 do not match. The detection unit 103 may, for example, display identifiable information for the production operation information 1120 or 1220 for which tampering has been detected on the display screen of the management terminal device 15. The detection unit 103 may, for example, turn on an alarm indicator light 16 when tampering is detected. Note that the production operation information communication control system 1 may, for example, include multiple alarm indicator lights 16 installed near each of the terminal device 11 and the production target device 12. In this case, the detection unit 103 may turn on an alarm indicator light 16 installed near the terminal device 11 or the production target device 12 that stores the production operation information 1120 or 1220 for which tampering has been detected.

[0045] The detection unit 103 may also use information other than the above-mentioned hash values ​​to detect tampering with the production operation information 1120 and 1220. For example, the detection unit 103 may detect tampering when the value of current meta information of a file, such as the timestamp of a file containing the production operation information 1120 and 1220, has been changed from the value when the file was in a state where its validity was guaranteed.

[0046] Next, the operation (processing) of the production operation information communication control system 1 according to the present disclosure will be described in detail with reference to the flowcharts of FIGS.

[0047] FIG. 2 is a flowchart showing the operation of the production operation information communication control system 1 according to the present disclosure, in which production operation information 1120 and 1220 are communicated between the terminal device 11 and the production target device 12.

[0048] The acquisition unit 101 of the management server 10 acquires configuration information 1041 including identification information of the terminal device 11, the production target device 12, and the communication relay devices 13 and 14 from the terminal device 11, the production target device 12, and the communication relay devices 13 and 14, and stores the acquired configuration information 1041 in the memory unit 104 (step S101). The reception unit 102 of the management server 10 receives, from the management terminal device 15, management information 1042 including a communication path for production work information 1120 from the terminal device 11 to the production target device 12, and a communication path for production work information 1220 from the production target device 12 to the terminal device 11, and stores the received management information 1042 in the memory unit 104 (step S102).

[0049] The communication unit 111 of the terminal device 11 encrypts the production work information 1120 using the encryption key, and the communication unit 121 of the production target device 12 encrypts the production work information 1220 using the encryption key (step S103). The communication unit 111 communicates the encrypted production work information 1120 from the terminal device 11 to the production target device 12 based on the configuration information 1041 and the management information 1042, and the communication unit 121 communicates the encrypted production work information 1220 from the production target device 12 to the terminal device 11 (step S104). The communication unit 111 decrypts the production work information 1220 communicated from the communication unit 121 using the decryption key, and the communication unit 121 decrypts the production work information 1120 communicated from the communication unit 111 using the decryption key (step S105), and the entire process ends.

[0050] FIG. 3 is a flowchart showing the operation of the production operation information communication control system 1 according to the present disclosure to detect tampering of the production operation information 1120 and 1220.

[0051] The terminal device 11 and the production target device 12 each calculate a master hash value 1043 of the production operation information 1120 and 1220 whose validity has been guaranteed, and register the master hash value 1043 in the storage unit 104 of the management server 10 in association with information that can identify the production operation information 1120 and 1220 (step S201). The detection unit 103 checks whether the timing has come to detect tampering with the production operation information 1120 and 1220 (step S202).

[0052] If the time has not come to detect tampering with the production work information 1120 and 1220 (No in step S203), the process returns to step S202. If the time has come to detect tampering with the production work information 1120 and 1220 (Yes in step S203), the detection unit 103 requests the terminal device 11 and the production target device 12 for the hash value 1044 of the current production work information 1120 or 1220 (step S204).

[0053] In response to a request from the detection unit 103, the terminal device 11 and the production target device 12 each calculate a hash value 1044 of the current production business information 1120 and 1220, and associate the hash value 1044 with information that can identify the production business information 1120 and 1220, and register it in the memory unit 104 of the management server 10 (step S205).

[0054] The detection unit 103 determines whether the hash value 1044 and the master hash value 1043 match for each of the production operation information 1120 and 1220 (step S206). If the hash value 1044 and the master hash value 1043 match for all of the production operation information 1120 and 1220 (Yes in step S207), the process returns to step S202. If the hash value 1044 and the master hash value 1043 do not match for at least any of the production operation information 1120 and 1220 (No in step S207), the detection unit 103 turns on the alarm indicator lights 16 installed near the terminal devices 11 and production target devices 12 that store the production operation information 1120 and 1220 for which the hash value 1044 and the master hash value 1043 do not match (step S208), and the overall process returns to step S202.

[0055] The production operation information communication control system 1 according to the present disclosure can avoid the problem of reduced operational efficiency when communicating production operation information to each device at a production site. This is because the production operation information communication control system 1 is a system that includes multiple terminal devices 11 and production target devices 12 that store production operation information 1120 and 1220 in a distributed manner, and communicates the production operation information 1120 and 1220 between the terminal devices 11 and the production target devices 12.

[0056] The effects achieved by the production operation information and communication control system 1 according to the present disclosure will be described in detail below.

[0057] Some production systems create a secure environment by transmitting and receiving production work information between terminal devices used in production operations and production target devices via a communication network, rather than via a recording medium such as a USB memory stick. However, in such production systems, production work information is typically transmitted from a management server that centrally manages the production work information to the terminal devices used in production operations and the production target devices. In this case, for example, communication congestion caused by the management server expanding the production work information may occur, which may extend the time required for each device to obtain the production information. Furthermore, if a failure occurs in the management server, each device may not be able to simultaneously obtain the production work information. In other words, in a production system in which production work information is centrally managed and communicated to each device, there is a risk of reduced operational efficiency at the production site, as described above.

[0058] To address these issues, the production operation information communication control system 1 according to the present disclosure acquires, from an external device, configuration information 1041 that represents the configuration of a system in which one or more terminal devices 11 that store multiple pieces of production operation information 1120 in a distributed manner and the production object devices 12 are communicably connected to the terminal devices 11 that process the individual pieces of production operation information 1120 and 1220 in response to user operations. The production operation information communication control system 1 then communicates the production operation information 1120 and 1220 between the terminal devices 11 and the production object devices 12 that are associated with each other in the management information 1042, based on the configuration information 1041. In other words, in the production work information communication control system 1, the storage locations of the production work information 1120 and 1220 are dispersed, and a situation in which access is concentrated on the management server 10 does not occur during the communication processing of the production work information 1120 and 1220, so the problem of reduced work efficiency when communicating production work information to each device at the production site can be avoided.

[0059] Furthermore, the production operation information communication control system 1 according to the present disclosure compares the production operation information 1120 and 1220 whose validity is guaranteed with the production operation information 1120 and 1220 at a predetermined time, and if the comparison results in a mismatch, detects that the production operation information 1120 and 1220 has been tampered with up until the predetermined time. This allows the production operation information communication control system 1 to improve the reliability of the production site.

[0060] Furthermore, the production operation information communication control system 1 according to the present disclosure encrypts the production operation information 1120 and 1220 and communicates the production operation information 1120 and 1220 between the terminal device 11 and the production target device 12. This enables the production operation information communication control system 1 to further improve the reliability of the production site.

[0061] The production operation information and communication control system 1 according to the present disclosure also includes communication relay devices 13 and 14 connected to the individual terminal devices 11 or production target devices 12 via a predetermined communication standard, such as USB, and transmits production operation information 1120 and 1220 between the terminal devices 11 and the production target devices 12 via the communication relay devices 13 and 14 that are communicatively connected to each other. The communication relay device 14 also has a function for starting up the production target devices 12 via the predetermined communication standard using the production operation information 1120 and 1220, which includes an OS image. This allows the production operation information and communication control system 1 to effectively utilize existing production systems that perform production operations using recording media that comply with existing communication standards, such as USB memory sticks, without making any changes to the systems.

[0062] <Modification of the first embodiment> 4 is a block diagram showing the configuration of a production operation information communication control system 1A according to the present disclosure. Note that, among the components included in the production operation information communication control system 1A, those components that have the same functions as the components included in the above-described production operation information communication control system 1 will be assigned the same numbers as the components included in the production operation information communication control system 1, and detailed descriptions thereof will be omitted.

[0063] In the above-described production work information and communication control system 1, communication relay devices 13 are communicatively connected to all terminal devices 11, and communication relay devices 14 are connected to all production target devices 12. In contrast, in the production work information and communication control system 1A, communication relay devices 13 are communicatively connected to some terminal devices 11A, and communication relay devices 14 are connected to some production target devices 12A. In the production work information and communication control system 1A, a parent-child relationship is formed among the multiple terminal devices 11A, and communication relay device 13 (first communication relay device) is connected only to parent terminal device 11A (first terminal device), and communication relay device 13 is not connected to child terminal device 11A (second terminal device). Similarly, in the production operation information and communication control system 1A, a parent-child relationship is formed among a plurality of production target devices 12A, and a communication relay device 14 (second communication relay device) is connected only to the parent production target device 12A (first production target device), while no communication relay device 14 is connected to the child production target device 12A (second production target device). In the present disclosure, the parent terminal device 11A is also referred to as the first terminal device, and the child terminal device 11A is also referred to as the second terminal device. In the present disclosure, the parent production target device 12A is also referred to as the first production target device, and the child production target device 12A is also referred to as the second production target device. In the present disclosure, the communication relay device 13 connected to the terminal device 11A is also referred to as the first communication relay device, and the communication relay device 14 connected to the production target device 12A is also referred to as the second communication relay device.

[0064] FIG. 5 is a diagram illustrating a parent-child relationship established between a terminal device 11A and a production target device 12A in a production operation information communication control system 1A according to the present disclosure.

[0065] In the present disclosure, as illustrated in FIG. 5, the number of the parent terminal device 11A is suffixed with "P," and the number of the child terminal device 11A is suffixed with "C." In the present disclosure, at least one of the parent terminal devices 11A or all of them may be referred to as terminal device 11A-P, and at least one of the child terminal devices 11A or all of them may be referred to as terminal device 11A-C. In the present disclosure, the number of the parent production target device 12A is suffixed with "P," and the number of the child production target device 12A is suffixed with "C." In the present disclosure, at least one of the parent production target devices 12A or all of them may be referred to as production target device 12A-P, and at least one of the child production target devices 12A or all of them may be referred to as production target device 12A-C.

[0066] In the production operation information and communication control system 1A illustrated in Fig. 5, terminal device 11A-2C is configured as a child of parent terminal device 11A-1P. Terminal devices 11A-4C and 11A-5C are configured as children of parent terminal device 11A-3P. Production target devices 12A-2C and 12A-3C are configured as children of parent production target device 12A-1P. Production target device 12A-5C is configured as a child of parent production target device 12A-4P. Communication relay devices 13-1 and 13-3 are connected to parent terminal devices 11A-1P and 11A-3P, respectively, while communication relay devices 13 are not connected to child terminal devices 11A-2C, 11A-4C, and 11A-5C. Similarly, communication relay devices 14-1 and 14-4 are connected to the parent production target devices 12A-1P and 12A-4P, respectively, while no communication relay device 14 is connected to the child production target devices 12A-2C, 12A-3C, and 12A-5C. Such a parent-child relationship between the terminal device 11A and the production target device 12A is indicated, for example, by configuration information 1041A stored in the storage unit 104 of the management server 10. Note that there is a predetermined upper limit to the number of terminal devices 11A-C or production target devices 12A-C configured as children of one parent.

[0067] In the production operation information communication control system 1A, the communication unit 111A of the parent terminal device 11A-1P communicates the production operation information 1120 stored in the memory unit 112 of the terminal device 11A-1P as well as the production operation information 1120 stored in the memory unit 112 of the child terminal device 11A-2C via the communication relay device 13-1. Similarly, the communication unit 111A of the parent terminal device 11A-3P communicates the production operation information 1120 stored in the memory unit 112 of the terminal device 11A-3P as well as the production operation information 1120 stored in the memory unit 112 of the child terminal devices 11A-4C and 11A-5C via the communication relay device 13-3. Similarly, the communication unit 121A of the parent production target device 12A-1P communicates the production work information 1220 stored in the memory 122 of the production target device 12A-1P as well as the production work information 1220 stored in the memory 122 of the child production target device 12A-2C and 12A-3C via the communication relay device 14-1. Similarly, the communication unit 121A of the parent production target device 12A-4P communicates the production work information 1220 stored in the memory 122 of the production target device 12A-4P as well as the production work information 1220 stored in the memory 122 of the child production target device 12A-5C via the communication relay device 14-4.

[0068] The communication unit 111A of the parent terminal devices 11A-P can access the production operation information 1120 stored in the memory unit 112 of the child terminal devices 11A-C by communicating with the communication unit 111A of the child terminal devices 11A-C via the communication network 18. Similarly, the communication unit 121A of the parent production target devices 12A-P can access the production operation information 1220 stored in the memory unit 122 of the child production target devices 12A-C by communicating with the communication unit 121A of the child production target devices 12A-C via the communication network 19.

[0069] The production operation information communication control system 1A according to the present disclosure can avoid the problem of reduced operational efficiency when production operation information is communicated to each device at the production site, for the reasons described above with respect to the production operation information communication control system 1.

[0070] Furthermore, in the production operation information and communication control system 1A according to the present disclosure, a first terminal device 11A-P (parent) connected to a first communication relay device 13 is communicatively connected to a second terminal device 11A-C (child) not connected to the first communication relay device 13. A first production object device 12A-P (parent) connected to a second communication relay device 14 is communicatively connected to a second production object device 12A-C (child) not connected to the second communication relay device 14. The communication unit 111A communicates production operation information 1120 between the second terminal device 11A-C and the first communication relay device 13 via the first terminal device 11A-P, and the communication unit 121A communicates production operation information 1220 between the second communication relay device 14 and the second production object device 12A-C via the first production object device 12A-P. As a result, the production operation information communication control system 1A can achieve the same effects as the above-mentioned production operation information communication control system 1 with a configuration that reduces costs by reducing the number of communication relay devices 13 and 14.

[0071] The parent-child relationship between the terminal device 11A and the production target device 12A may be established based on, for example, the similarity in the attributes of the production operation information 1120 stored in the storage unit 112 and the production operation information 1220 stored in the storage unit 122. The parent-child relationship between the production target device 12A may also be established based on, for example, the similarity in the attributes of the production target device 12A (such as the type of product). Terminal devices 11A or production target devices 12A that store similar attributes of the production operation information 1120 or 1220 are more likely to share the same production operation information 1120 or 1220. Therefore, by grouping the terminal devices 11A or production target devices 12A that store similar attributes of the production operation information 1120 or 1220 as children of the same parent, it is expected that the communication of the production operation information 1120 or 1220 will be more efficient.

[0072] <Second embodiment> 6 is a block diagram showing the configuration of a production operation information communication control system 2 according to the present disclosure. The production operation information communication control system 2 includes an acquisition unit 201, a reception unit 202, and a communication unit 203. The acquisition unit 201, the reception unit 202, and the communication unit 203 are examples of an acquisition means, a reception means, and a communication means, respectively.

[0073] The acquisition unit 201 acquires, from an external device, configuration information 2010 representing the configuration of a system in which one or more terminal devices 21, which store a plurality of pieces of production operation information 200 in a distributed manner, and the production operation devices 22 are communicatively connected to the terminal devices 21. The terminal device 21 is, for example, a device similar to the terminal device 11 in the production operation information communication control system 1. The production operation device 22 is, for example, a device similar to the production operation information 12 in the production operation information communication control system 1. The configuration information 2010 is, for example, information similar to the configuration information 1041 in the production operation information communication control system 1. The acquisition unit 201 operates in the same manner as the acquisition unit 101 in the production operation information communication control system 1.

[0074] The reception unit 202 receives management information 2020 that indicates the correspondence between the terminal device 21 that processes each piece of production operation information 200 in response to a user's operation and the production target device 22. The management information 2020 is, for example, information similar to the management information 1042 related to the production operation information communication control system 1. The reception unit 202 operates in the same manner as the reception unit 102 related to the production operation information communication control system 1, for example.

[0075] The communication unit 203 communicates production operation information 200 based on configuration information 2010 between the terminal device 21 and the production target device 22 that are associated with each other in the management information 2020. The communication unit 203 operates in the same manner as the communication unit 111 or 121 of the production operation information communication control system 1, for example.

[0076] Next, the operation (processing) of the production operation information and communication control system 2 according to the present disclosure will be described in detail with reference to the flowchart of FIG.

[0077] The acquisition unit 201 acquires configuration information 2010 of the production operation information communication control system 2 (step S201). The reception unit 202 receives management information 2020 that indicates the correspondence between the terminal device 21 that processes the production operation information 200 in response to a user's operation and the production target device 22 (step S202). The communication unit 203 communicates the production operation information 200 between the terminal device 21 and the production target device 22 that are associated with each other in the management information 2020 based on the configuration information 2010 (step S203), and the entire process ends.

[0078] The production operation information communication control system 2 according to the present disclosure can avoid the problem of reduced operational efficiency when communicating production operation information to each device at the production site. The reason for this is that the production operation information communication control system 1 is a system including multiple terminal devices 21 and production target devices 22 that store production operation information 200 in a distributed manner, and communicates the production operation information 200 between the terminal devices 21 and the production target devices 22.

[0079] <Hardware configuration example> In each of the above-described embodiments, each unit in the production operation information and communication control system shown in Figures 1, 4, and 6 can be realized by dedicated HW (Hardware) (electronic circuitry). In Figures 1, 4, and 6, at least the following components can be considered as functional (processing) units (software modules) of a software program containing instructions executed by a processor.

The functions are the above-mentioned configurations in the block diagrams (FIGS. 1, 4, and 6) or the functions of the flowcharts (FIGS. 2, 3, and 7) referred to in the description of the embodiment.

The computer program supplied to the device may be stored in a readable / writable volatile memory (RAM 903) or a non-volatile storage device such as a ROM 902 or a hard disk 904.

[0085] In the above case, the method of supplying the computer program to the hardware can be a currently common procedure, such as installing the program in the device via a recording medium 907 such as a CD-ROM, or downloading the program from an external source via a communication line such as the Internet. In such a case, the present invention can be considered to be constituted by the code constituting the computer program or the recording medium 907 on which the code is stored.
