[Figure 9] This is an explanatory diagram illustrating the hardware configuration of each device according to the said embodiment. [Modes for carrying out the invention]

[0015] Embodiments of this disclosure will be described below with reference to the drawings. Figure 1 is a schematic block diagram showing the configuration of a monitoring and control system 100 for a power system 30 according to one embodiment of this disclosure. The power system 30 may be either a power transmission system or a power distribution system. Control devices such as circuit breakers, switches, and transformers are arranged in the power system 30. The monitoring and control system 100 monitors and controls these control devices via electronic devices such as IEDs (Intelligent Electric Devices) that are connected to the system via communication means compliant with international standards such as IP (Internet Protocol) networks.

[0016] The monitoring and control system 100 includes an HMI (Human Machine Interface) device 10 (information processing device) and a system monitoring and control device 20. The HMI device 10 and the system monitoring and control device 20 are communicably connected by communication means such as an IP network. The HMI device 10 edits a power system diagram used in the monitoring and control system 100 of the power system 30. Also, the HMI device 10 is installed, for example, inside an electrical substation and provides an interface for a user such as an electrical substation staff to monitor and control the power system 30 by the system monitoring and control device 20. The power system diagram edited by the HMI device 10 is used for this interface. The number of control devices that can be monitored or controlled by the HMI device 10 is, for example, 100 units. The HMI device 10 may be realized by one or more computers reading and executing a program.

[0017] The system monitoring and control device 20 monitors and controls the power system 30. The system monitoring and control device 20 acquires or controls the state of control devices arranged in the power system 30 via electronic devices such as IEDs communicably connected by an IP network. The system monitoring and control device 20 may be realized by one or more computers reading and executing a program.

[0018] FIG. 2 is a schematic block diagram showing the configuration of the HMI device 10 in the present embodiment. The HMI device 10 includes a display position specifying unit 11, a control device information acquisition unit 12, an association specifying unit 13, a consistency check unit 14, a system diagram information storage unit 15, a control device state acquisition unit 16, a system diagram display unit 17, a device control unit 18, and an edit history display unit 19.

[0019] The display position specifying unit 11 provides an interface for specifying the display position in the power system diagram of an object indicating each device (control device) to be monitored or controlled in the power system 30. For example, the display position may be specified by the user arranging the object in the power system diagram using a pointing device such as a mouse. The display position specifying unit 11 stores the specified display position in the system diagram information storage unit 15.

[0020] The control device information acquisition unit 12 acquires device data that includes identification information for each of the multiple control devices. For example, the control device information acquisition unit 12 may acquire device data from a file specified by the user by reading the file. For example, the identification information may include a network address (such as an IP address) for monitoring or controlling the control device, a control device name (for example, a position name within the power system 30), both, or other information related to the control device.

[0021] The mapping specification unit 13 provides an interface for specifying the mapping between each object and identification information. For example, this mapping may be specified by the user selecting the object and identification information using an input device such as a mouse or keyboard. The mapping specification unit 13 stores the mapping results in the system diagram information storage unit 15.

[0022] The consistency check unit 14 verifies the consistency between the identification information associated with an object by the mapping specification unit 13 and the identification information contained in the equipment data. For example, if the control equipment information acquisition unit 12 acquires equipment data after the identification information has been associated with an object by the mapping specification unit 13, the consistency check unit 14 may verify whether the identification information associated with the object is included in the equipment data. If the identification information includes multiple items, the consistency check unit 14 may verify whether the combination of these items matches between the identification information associated with the object and the identification information contained in the equipment data.

[0023] The system diagram information storage unit 15 stores system diagram information for each object included in the power system diagram, including its display position, identification information of the corresponding control device, and the status of the corresponding control device. The system diagram information storage unit 15 also stores the change history (editing history) of the system diagram information.

[0024] The control device status acquisition unit 16 acquires the status of each control device from the system monitoring and control device 20. The status of a control device is, for example, its open or closed state if the control device is a switch or circuit breaker. The status of a control device may also include the status of the power system, such as the voltage at that control device. The control device status acquisition unit 16 stores the acquired status in the system diagram information storage unit 15.

[0025] The system diagram display unit 17 displays a power system diagram on a display such as a liquid crystal display or an organic EL (Electro Luminescence) display provided by the HMI device 10, based on the system diagram information stored in the system diagram information storage unit 15. The system diagram display unit 17 also provides an interface for inputting control instructions to control equipment.

[0026] The equipment control unit 18 transmits the control instructions input by the system diagram display unit 17 to the system monitoring and control device 20.

[0027] The editing history display unit 19 displays the editing history of the power system diagram and the object-to-identification information mapping, along with information indicating the editor (user), on the display provided by the HMI device 10.

[0028] Figure 3 shows an example of the first display screen of the HMI device 10 in this embodiment. Figure 3 is the system diagram creation screen. Objects OB1 and OB2 are power system diagram objects that correspond to the controlled equipment and are arranged by the interface provided by the display position specification unit 11. List LT1 is a list that is displayed when, for example, the mouse is right-clicked on object OB1, and is a list for performing operations on object OB1. "Copy" in list LT1 is an operation to copy object OB1, "Paste" is an operation to paste already copied information onto object OB1, and "Position Assignment" is an operation to associate identification information with object OB1.

[0029] Figure 4 shows an example of a second display screen of the HMI device 10 in this embodiment. Figure 4 is the system diagram creation screen when "Position Assignment" is selected in Figure 3. Dialog DL1 is a dialog for reading a file containing control data, and is provided by the control equipment information acquisition unit 12. This file is, for example, a file containing equipment data generated from the design information of the electric station where the HMI device 10 is installed.

[0030] Figure 5 shows an example of the third display screen of the HMI device 10 in this embodiment. Figure 5 is the system diagram creation screen after "Load" is selected in Figure 4, that is, after the file containing the control data has been loaded. Dialog DL2 is a dialog for associating identification information (address name and position name) with object OB1 of object number 001, and is provided by the association specification unit 13. List LT2 is a candidate list of identification information to associate with object OB1. In List LT2, for example, "CB1" is the position name and "XX.XX.XX.XX" is the address name. When any of the identification information in the candidate list of List LT2 is specified, the association specification unit 13 displays the address name and position name of the specified identification information in the address name and position name of Dialog DL2. List LT2 may also be a candidate list based on the equipment data stored in the file specified and loaded in Dialog DL1 in Figure 4.

[0031] Figure 6 shows an example of a fourth display screen of the HMI device 10 in this embodiment. Figure 6 is the system diagram creation screen after "Load" is selected in Figure 4, that is, after the file containing the control data has been loaded. Dialog DL3 is a dialog for associating identification information (address name and position name) with object OB1 of object number 001, and is provided by the association specification unit 13. List LT3 is a candidate list of identification information to associate with object OB1, but the content of the address names differs from that of list LT2. The consistency check unit 14 determines that there is an inconsistency because the address name "XX.XX.XX.XX" associated with object OB1 of object number 001 does not exist in the candidate list of list LT3, and highlights the address name field (for example, in red). The consistency check unit 14 may also highlight object OB1 that it has determined to be inconsistent even if dialog DL3 is not open.

[0032] Figure 7 shows an example of a fifth display screen of the HMI device 10 in this embodiment. Figure 7 is the edit history screen displayed by the edit history display unit 19. In the example of Figure 7, the edit history table displays the edit date and time, object, editor, and edit content in each row. The edit date and time shows the year, month, day, hour, and minute when the edit was made, such as "2024 / 08 / 01, 13:05". Note that the edit date and time is not limited to year, month, day, hour, and minute; for example, it may be year, month, and day, or year, month, day, hour, minute, and second. The object shows the object that was edited, such as "Object 001". The editor shows the user who made the edit (change), such as "A". The edit content shows the edit content, such as "Changed address name from XX.XX.XX.XX to YY.YY.YY.YY".

[0033] Figure 8 is a table showing an example of system diagram information stored by the system diagram information storage unit 15 in this embodiment. In the table in Figure 8, each row includes object number, display position, position name, address name, and status. The object number is, for example, "001", and is a number that identifies the object in the power system diagram. The display position is, for example, "30,50", and is the coordinate (X coordinate, Y coordinate) in the power system diagram where the object with the corresponding object number is displayed. The position name is, for example, "CB1", and is the position name of the control device corresponding to the object with the corresponding object number. The address name is, for example, "XX.XX.XX.XX", and is the network address of the control device corresponding to the object with the corresponding object number. The status is, for example, "Closed", and is the status of the control device corresponding to the object with the corresponding object number.

[0034] Figure 9 is an explanatory diagram illustrating the hardware configuration of each device according to this embodiment. Each device is an HMI device 10 and a system monitoring and control device 20. Each device consists of an input / output module I, a memory module M, and a control module P.

The memory module M is implemented by including a drive H7. The memory module M may further consist of some or all of a memory H8. The control module P is implemented by including a memory H8 and a processor H9. These hardware components are connected to each other via a bus so as to be able to communicate with each other and are powered by a power supply H6.

[0035] The connection module H12 is a digital input / output port such as USB (Universal Serial Bus). The pointing device H21, keyboard H22, and display H23 may be touch panels. The sensor H52 is an accelerometer, gyroscope, GPS receiver module, proximity sensor, etc. The power supply H6 is a power supply unit that supplies the electricity necessary to operate each device. The power supply H6 may be a battery. The drive H7 is an auxiliary storage medium such as a hard disk drive or solid state drive. The drive H7 may be a non-volatile memory such as EEPROM or flash memory, or a magneto-optical disk drive or flexible disk drive. Furthermore, the drive H7 is not limited to one built into each device, for example, but may also be an external storage device connected to the connector of the connection module H12. The memory H8 is a main memory medium such as random access memory. Note that the memory H8 may be cache memory. The memory H8 stores instructions when they are executed by one or more processors H9. The processor H9 is the CPU (Central Processing Unit). The processor H9 may be an MPU (microprocessing unit) or a GPU (graphics processing unit). The processor H9 reads programs and various data from drive H7 via memory H8 and performs calculations to execute instructions stored in one or more memory H8s.

[0036] Input / output module I is used in the HMI device 10, the system monitoring and control device 20, etc. Control module P is used for the implementation of each part of the HMI device 10 and the system monitoring and control device 20.
