Description

  The present invention relates to a control system and a control method for controlling setting information.

  There is a system in which setting information is registered from an external device via a network for devices in a predetermined facility, and each device in the facility is controlled based on the setting information. For example, the devices in the substation are constructed in conformity with IEC 61850, which is an international standard, and each device in the substation is controlled based on setting information defined in IEC 61850. Examples of equipment in the substation include intelligent electronic devices (IEDs) and main devices.

  For example, there is a technique described in Patent Document 1 as a technique for controlling each device in a facility such as a substation. In the facility control system described in Patent Document 1, a field device (for example, IED) function is installed in a control station, and a communication link is formed between the device function and the control station to integrate the field device.

JP 2001-202104 A

  Here, in IEC61850, IED settings are described in a configuration file called a CID (Configured IED Description) file. Hereinafter, the setting file is also referred to as setting information. In the setting information, the setting value of the data model can be described in addition to the definition of the IED data model and the communication setting.

  The IED captures setting information via a dedicated setting tool. The fetching of the setting information is performed as a maintenance work. Hereinafter, this processing is also referred to as offline setting. A data model is generated based on the setting information set in the offline setting, and the device is controlled using the setting value of the data model.

  On the other hand, the setting value of the data model can be changed by communication from a client compliant with IEC61850. Hereinafter, this process is also referred to as online setting.

  When the setting value of the data model is changed by the online setting of the IED, the IED operates with a setting different from the setting value of the setting information first set offline by the setting tool.

  When the setting value of the data model is changed by the above online setting, the device is controlled using the changed setting value of the data model, but the change is not reflected in the setting information used during the offline setting. . Because there is no room to analyze the setting information as it is from the viewpoint of the resources of the IED device, it is considered that the data format of the setting information is converted on the management side and the setting information is held in an IED original format. Because. Therefore, even if the setting value of the data model is changed, the current situation is that the changed content is not directly reflected in the setting information.

  Even if the device receives the setting information in the original data format, analyzes it at the time of start-up, and reflects it in the setting value of the data model, the reverse, that is, the setting value in the data model is the setting information of the original data format. There are cases where it is difficult to reflect on

  Normally, to update the setting information file, it is necessary to read the entire file into memory. At startup, the memory used for other purposes can be temporarily used during operation, but in order to reflect the setting value in the data model in the setting information file in the operating device, the file size must be changed. Accordingly, the memory capacity of the device must be increased.

  For this reason, the device can analyze the setting information, but currently does not have a function to rewrite the original setting information or a function to reflect the contents held in the data model to the original setting information. It is.

  Further, there are cases where it is difficult to completely restore the setting information only with the information included in the data model. This is because not all setting values included in the setting information are reflected in the data model.

  Considering the above situation, the following problems occur. For example, when changing the setting of an operating control system that conforms to IEC 61850, if the setting contents are examined based on the initial setting information acquired from the management apparatus by the operator, there is an inconsistency with the actual IED setting. May occur. Due to this inconsistency, there is a possibility that useless setting value adjustment may occur or an appropriate setting value cannot be set.

  Therefore, it is important to acquire setting information that reflects the actual setting of the IED. However, in the prior art, when the setting value is changed from a client conforming to IEC 61850, the setting contents of the IED data model and the setting contents of the setting information on the management apparatus cannot be matched, and the latest setting information It becomes difficult to acquire the set value.

  Further, the above problem is not limited only to a system conforming to IEC61850. For example, even when it is possible to change the setting value of the data model from another device with respect to the device controlled by the setting information acquired from the management apparatus and controlled using the data model generated from the setting information Similar problems occur.

  SUMMARY OF THE INVENTION The present invention is directed to a control system in which device setting information is registered by a management device, and the setting information managed on the management device side can be matched with the setting information stored on the device side. To do.

  The control unit 201 requests the electronic device 30 to change the setting value via the LAN communication unit 203. For example, the control unit 201 can change a setting value of a data model in the electronic device 30 described later.

  The LAN communication unit 203 transmits and receives data to and from the LAN communication unit 311 of the electronic device 30 via the LAN. For example, the LAN communication unit 203 transmits a data model setting value change request to be described later to the electronic device 30.

  The electronic device 30 illustrated in FIG. 2 includes a tool communication unit 301, a control unit 303, a first storage unit 305, a second storage unit 307, a third storage unit 309, and a LAN communication unit 311. Each unit in the electronic device 30 is connected to each other via a bus so that data can be exchanged.

  The tool communication unit 301 transmits / receives data to / from the tool communication unit 105 of the management apparatus 10 via a communication network. For example, the tool communication unit 301 receives a registration request for the setting information A or the setting information B obtained by converting the setting information A from the management apparatus 10, receives a request for acquiring file information and setting change information, File information and setting change information are transmitted to the apparatus 10.

  The control unit 303 executes a request acquired from the tool communication unit 301 or executes a request acquired from the LAN communication unit 311. For example, the control unit 303 registers setting information, generates a data model from the setting information, and changes setting information of the data model. Details of the control unit 303 will be described later with reference to FIG.

  The first storage unit 305 is a non-volatile memory such as a flash memory, for example, and functions as a file system that stores the setting information A or the setting information B. In the example illustrated in FIG. 2, the first storage unit 305 stores setting information B.

  The LAN communication unit 311 transmits / receives data to / from the LAN communication unit 203 of the information processing apparatus 20 via the LAN. For example, the LAN communication unit 311 receives a data model setting value change request from the information processing apparatus 20.

<Functional configuration>
Next, functions of each control unit will be described. FIG. 3 is a block diagram illustrating an example of functions of the control unit 103 of the management apparatus 10 in the embodiment. In the following description, the control system 1 will be described by taking a system based on IEC 61850 as an example. The example illustrated in FIG. 3 is an example in which the setting information A is converted into setting information B on the management apparatus 10 side.

  The control unit 103 includes a format conversion unit 131, a registration unit 133, a request unit 135, and an update unit 137. Each unit in the control unit 103 functions by executing a predetermined program.

  The format conversion unit 131 converts the setting information A stored in the management device 10 into a data format for the electronic device 30. For example, the format conversion unit 131 divides the setting information A (for example, a CID file) in the xml format into a plurality of files or converts it into a binary unique format so that the electronic device 30 can easily handle the setting information. The setting information before conversion is expressed as setting information A, and the setting information after conversion is expressed as setting information B.

  In many cases, the electronic device 30 does not have sufficient resources for analyzing xml. Therefore, the management device 10 may convert the setting information so that the electronic device 30 can easily handle it, and register the converted setting information in the electronic device 30.

  The registration unit 133 registers the setting information B converted by the format conversion unit 131 with the electronic device 30 via the tool communication unit 105. In addition, when the content of the setting information is changed and updated, the registration unit 133 sends the setting information B obtained by converting the updated setting information to the electronic device 30 according to an instruction from the maintenance worker, for example. Registration is performed via the tool communication unit 105.

  The request unit 135 requests the acquisition of file information and setting change information stored in the electronic device 30 via the tool communication unit 105 according to an instruction from the maintenance worker.

  The update unit 137 updates the setting information A based on the file information and the setting change information acquired in response to the acquisition request from the request unit 135. For example, the update unit 137 specifies the ID, version, and revision number of the setting information, searches the storage unit 101, and acquires the corresponding setting information A. The update unit 137 rewrites the setting value of the setting information A of the corresponding setting item to the setting value of the setting change information. When all the contents of the setting change information are reflected, the updating unit 137 updates the revision number and stores the new setting information A in the storage unit 101.

  Note that the data format of the setting information stored in the management device 10 and the electronic device 30 may be unified. In this case, the management device 10 does not need to provide the format conversion unit 131, but an analysis unit that analyzes the setting information A is provided on the electronic device 30 side. For example, the analysis unit analyzes the original setting information A at the time of activation, and reflects the setting value included in the setting information A in the data model.

  The analysis unit analyzes and captures the original setting information in the same manner as the format conversion unit 131. However, the analysis unit directly reflects the setting value extracted from the original setting information on the data model. Is different. Further, the function of this analysis unit may be provided to a data model generation unit 335 described later.

  FIG. 4 is a block diagram illustrating an example of functions of the control unit 303 of the electronic device 30 in the embodiment. In the example illustrated in FIG. 4, the electronic device 30 acquires the setting information B obtained by converting the setting information A.

  The control unit 303 illustrated in FIG. 4 includes a registration unit 331, a file information generation unit 333, a data model generation unit 335, a setting change unit 337, and a change information generation unit 339. Each unit in the control unit 303 functions by executing a predetermined program.

  The registration unit 331 stores the setting information B acquired together with the registration request received by the tool communication unit 301 in the first storage unit 305.

  The file information generation unit 333 detects that the setting information B has been stored in the first storage unit 305, and in order to identify the setting information B, reads the ID, version, and revision number of the setting information B to obtain the file information. Generate. The file information generation unit 333 stores the generated file information in the third storage unit 309.

  When the electronic device 30 is activated, the data model generation unit 335 generates a data model in the second storage unit 307, reads the setting information B from the first storage unit 305, and uses the setting value in the setting information B as the data model. reflect.

  In addition, when the setting change is stored in the third storage unit 309, the data model generation unit 335 reflects the setting value in the setting change information in the data model after the setting value of the setting information B is reflected.

  In this case, the data model generation unit 335 is generated based on the setting information B stored in the first storage unit 305 and the setting change information stored in the third storage unit 309, for example, when the electronic device 30 is restarted. In addition, the data model having the changed set value is stored in the second storage unit 307.

  Therefore, when the electronic device 30 is restarted, a data model reflecting the latest setting value can be generated, and the main device 40 can be controlled with the latest setting value.

  The setting change unit 337 changes the setting value of the data model based on the change request received by the LAN communication unit 311.

  When the change information generation unit 339 detects that the setting value of the data model has been changed, the change information generation unit 339 generates setting change information including the changed setting item and the changed setting value.

<Various data>
Next, specific examples of various data used in the embodiment will be described. FIG. 5 is a diagram illustrating an example of the setting information A. The setting information A shown in FIG. 5 is an example of a CID file and is described in an xml format. The setting information A illustrated in FIG. 5 is stored in the storage unit 101 of the management apparatus 10.

  FIG. 6 is a diagram illustrating an example of the setting information B. The setting information B shown in FIG. 6 has a data format converted by the format conversion unit 131 based on the setting information A shown in FIG. For example, the information of the part P11 of the setting information B indicates the management information of the CID file and is generated from the Header element shown in FIG.

  Further, the information of the part P12 of the setting information B indicates the setting information of the CID file and is generated from the elements of the electronic device 30 shown in FIG. In addition, the setting information B illustrated in FIG. 6 is stored in the first storage unit 305 of the electronic device 30.

  FIG. 7 is a diagram illustrating an example of file information. The file information shown in FIG. 7 is generated by reading the file ID, version, and revision number by the file information generation unit 333 based on the setting information B shown in FIG. In the example shown in FIG. 7, file information including ID “sample”, version “1.0”, and revision number “1” is generated.

  The file information may be generated based on the analysis result of the setting information A. In this case, setting information A is stored in the first storage unit 305, and the file information generation unit 333 performs file information based on a setting value acquired by analyzing the setting information A by an analysis unit (not shown). Is generated.

  FIG. 8 is a diagram illustrating an example of a data model (part) before the change. The data model shown in FIG. 8 is a part of the data model generated by the data model generation unit 335 based on the setting information B shown in FIG.

  For example, in the CID file, a setting value “direct-with-normal-security” is described in the <Val> element. This setting value is defined as an enumeration in the <DataTypeTemplate> element, and the corresponding value is 1. The data model reflecting this setting value is shown in FIG. 8, the data item is “LD1 $ CBR0 $ CF $ Pos $ ctlModel”, the type of the data item is “setting”, and the value is “1”. is there.

  Here, a case where data on the data model is rewritten online from the information processing apparatus 20 will be described. For example, it is assumed that the information processing apparatus 20 requests the electronic apparatus 30 to write the setting value “3” to the data item specified by “LD1 $ XCBR0 $ CF $ Pos $ ctlModel” illustrated in FIG.

  The setting change unit 337 of the electronic device 30 receives the change request from the LAN communication unit 311 and writes the corresponding data on the data model. At this time, if the type is “setting”, the change information generation unit 339 writes the corresponding data in the setting change information.

  FIG. 9 is a diagram illustrating an example of the data model (part) after the change. In the data model shown in FIG. 9, the setting value is changed from “1” to “3” from the data model shown in FIG.

  FIG. 10 is a diagram illustrating an example of the setting change information. The setting change information illustrated in FIG. 10 is information generated by the change information generation unit 339 with respect to the changed data model illustrated in FIG. The setting change information includes a setting item (data item) name and a changed setting value.

  FIG. 11 is a diagram illustrating an example of the updated setting information A. 11 is information updated by the update unit 137 based on the setting change information shown in FIG. 10 and the file information shown in FIG.

  In the setting information A shown in FIG. 11, the <Val> element of <IED> is changed to “direct-with-enhanced-security” corresponding to the setting value “3”. In addition, “revision” is updated to “2”.

  Thereby, the setting information held by the management apparatus 10 and the latest setting information of the electronic apparatus 30 can be matched. The updated setting information A is stored in the storage unit 101 as new information, and its history is recorded in the management table.

  FIG. 12 is a diagram illustrating an example of the management table. The management table shown in FIG. 12 includes a management number, a file name, an ID, a version (version), and a revision (revision).

  The management number is a number assigned to manage the setting information file. The file name is the file name of the setting information. The ID is an ID for identifying setting information. The version represents the version of the setting information. The revision represents the number of times the setting information is corrected. For example, the setting information with the management number “3” is setting information obtained by updating (correcting) the setting information with the management number “1”. By managing the setting information with the management table, it is possible to leave a history of the setting information, and the operator can acquire appropriate setting information as necessary.

<Operation>
Next, operation | movement of the control system 1 in an Example is demonstrated. Below, operation | movement of the control system 1 in each scene is demonstrated in order.

<< Registration of setting information >>

FIG. 13 is a sequence diagram illustrating an example of the setting information registration process. In step S <b> 101 illustrated in FIG. 13, the maintenance worker activates the electronic device 30 using the maintenance tool of the management device 10. For example, an operation to turn on the electronic device 30 is performed.

  In step S <b> 102, the maintenance worker instructs the management apparatus 10 to write setting information. The setting information is, for example, a CID file.

  In step S <b> 103, the management apparatus 10 (registration unit 133) transmits setting information to the electronic apparatus 30. At this time, the management apparatus 10 may transmit the setting information by converting the data format of the setting information by the format conversion unit 131 or may transmit the original setting information.

The management apparatus 10 notifies the maintenance worker, for example, by displaying the completion of writing on the display screen.

  FIG. 14 is a flowchart illustrating an example of setting information storage processing. In step S201 illustrated in FIG. 14, the electronic device 30 (registration unit 331) stores the received setting information in the first storage unit 305.

  In step S202, the electronic device 30 (file information generation unit 333) reads the ID, version, and revision number of the setting information and records them in the file information of the third storage unit 309.

  In step S203, the electronic device 30 deletes the setting change information stored in the third storage unit 309. This is because the setting information stored in the first storage unit 305 this time is the latest information, and the setting change information is deleted.

《Electronic device activation》
Next, processing when the electronic device 30 is activated will be described. FIG. 15 is a sequence diagram illustrating an example of a startup process of the electronic device 30. In step S301 illustrated in FIG. 15, the driving operator activates the electronic device 30. For example, the driving operator performs an operation of turning on the electronic device 30. In step S302, the electronic device 30 performs a setting information reading process.

  FIG. 16 is a flowchart illustrating an example of setting information reading processing. In step S401, the electronic device 30 (data model generation unit 335) analyzes the setting information stored in the first storage unit 305 and extracts the setting value when the power is turned on.

  In step S <b> 402, the electronic device 30 (data model generation unit 335) reflects the setting value of the setting information in the corresponding item of the data model stored in the second storage unit 307.

  In step S403, the electronic device 30 (data model generation unit 335) determines whether or not setting change information is stored in the third storage unit 309. If the setting change information is stored (step S403-YES), the process proceeds to step S404. If the setting change information is not stored (step S403-NO), the process ends.

  In step S <b> 404, the electronic device 30 (data model generation unit 335) reflects the setting change information stored in the third storage unit 309 in the corresponding item of the data model stored in the second storage unit 307.

<< Data Write (Change) from Information Processing Apparatus 20 >>

<Summary>
The electronic device controls the device based on the setting value of the data model. There is a technique for standardizing information exchange (for example, IEC 61850) between an electronic device and a management device that manages the electronic device and between electronic devices. By using this technology, the interoperability of the multi-vendor system can be improved and the life cycle cost of the system can be reduced.

  The electronic device sets the setting value of the data model based on the setting information obtained by standardized information exchange.

  However, electronic devices have limited resources. For this reason, when the setting value of the data model is directly changed by the online setting, the setting information managed by the management apparatus is not changed. Therefore, a contradiction arises in the setting values held by the electronic device and the management device.

  With respect to the above problem, the control system according to the present embodiment can match the setting information held by the management apparatus with the setting information for controlling the device by the electronic apparatus.
