Description

Supervisory control system, server, backup processing method, and backup processing program

The present disclosure relates to a supervisory control system, a server, a backup processing method, and a backup processing program that monitor and control objects to be monitored and controlled.

Conventionally, redundant monitoring and control systems equipped with backup functions have been known so that functions can be maintained in case of failure. In addition, in the redundancy of the supervisory control system, it is being studied to arrange a backup device at a remote location and perform disaster recovery in preparation for a large-scale disaster. In order to perform disaster recovery, the backup device must have the same data as the main device in addition to the monitoring control function.

However, the data of the main unit includes the measurement data itself transmitted from the monitoring control equipment and the intermediate data in the process of converting the measurement data into processed data. can be difficult to periodically synchronize with a backup device. Therefore, for example, Japanese Patent Laid-Open No. 2002-200003 proposes a technique for distributing and backing up data output from a monitoring control device to a plurality of clients.

In order to solve the above-described problems and achieve the purpose, the supervisory control system of the present disclosure includes multiple gateway devices and a server. A plurality of gateway devices are communicably connected to a plurality of monitoring control devices. The server collects measurement data transmitted from a plurality of monitoring control devices via a plurality of gateway devices, and monitors and controls a monitoring control target based on the collected measurement data. The server includes a resource data acquisition section, a setting data storage section, and a backup processing section. The resource data acquisition unit periodically acquires resource data indicating the resource usage status of each of the plurality of gateway devices. The setting data storage unit stores setting data including method data including data indicating a backup method and condition data indicating backup conditions for each target data included in backup data, which is data to be backed up. The backup processing unit distributes and stores the backup data in a plurality of gateway devices while changing the backup method based on the resource data and setting data periodically acquired by the resource data acquisition unit.

According to the present disclosure, it is possible to more appropriately distribute and store backup data.

Also, the measurement data processing unit 23 processes the measurement data of the plurality of monitoring control devices 1 to generate processed data. The processed data is data suitable for monitoring control, and includes, for example, data obtained by thinning out the measurement data, statistical data of the measurement data, or data obtained from multiple types of measurement data.

The measurement data processing unit 23 causes the monitoring control data storage unit 30 to store the processed data generated by processing the measurement data. The measurement data processing unit 23 also causes the monitoring control data storage unit 30 to store intermediate data obtained when generating the processed data. Thus, the monitoring control data stored in the monitoring control data storage unit 30 includes measurement data, intermediate data, processed data, and the like.

The monitoring control processing unit 24 monitors and controls the monitoring control target based on the processed data of the monitoring control data stored in the monitoring control data storage unit 30 . For example, the monitoring control processing unit 24 generates monitoring screen data for monitoring and controlling the monitoring control target based on the processed data of the monitoring control data stored in the monitoring control data storage unit 30. The data of the monitored screen obtained is transmitted to the client device 3 via the communication unit 20 . When receiving the monitoring screen data, the client device 3 causes a display unit (not shown) to display the monitoring screen based on the monitoring screen data.

The resource data acquisition unit 25 periodically acquires resource data transmitted from each gateway device 2 . For example, the resource data acquisition unit 25 acquires resource data periodically transmitted from each gateway device 2 and received by the communication unit 20 from the communication unit 20 .

The backup processing unit 26 distributes the monitoring control data stored in the monitoring control data storage unit 30 as backup data based on the resource data of the plurality of gateway devices 2 periodically obtained by the resource data obtaining unit 25. It is stored in a plurality of gateway devices 2.

The backup processing unit 26 includes a backup method determination unit 40 and a backup execution unit 41 . Based on the setting data stored in the setting data storage unit 31 and the resource data acquired by the resource data acquisition unit 25, the backup method determination unit 40 performs backup for each target data included in the monitoring control data to be backed up. Decide how and where to back up For example, the backup method determination unit 40 determines the backup method and backup destination for each target data each time the resource data of each gateway device 2 is acquired by the resource data acquisition unit 25 or at a preset cycle.

The backup method includes the data period and backup cycle of the data to be backed up. The data period indicates how long ago the target data is to be backed up. If the data period is one hour, the data to be backed up is, for example, the measurement data from one hour ago to the present, the intermediate data generated from the measurement data from one hour ago to the present, and the data from one hour ago to the present. This is processed data generated from the measurement data of .

The backup cycle indicates the backup cycle, which is the cycle for backing up the target data. For example, if the backup cycle is 3 minutes, the target data backed up in the gateway device 2 is updated every 3 minutes.

The setting data stored in the setting data storage unit 31 is data including method data including data indicating a backup method and condition data indicating backup conditions for each target data. The condition data is data indicating resource state conditions.

FIG. 4 is a diagram depicting an example of setting data stored in a setting data storage unit according to the first embodiment; As shown in FIG. 4, the setting data stored in the setting data storage unit 31 includes "data ID (identifier)", "data type", "data name", "backup condition", "backup method", and " priority” for each target data.

"Data ID" is identification data unique to each target data. The "data type" is data indicating the name of the data type of the target data, and the "data name" is data indicating the name of the target data.

"Backup condition" is data indicating the backup condition of the target data, and includes "memory free space", "HDD free space", and the like. “Free memory capacity” is data indicating the condition of the free memory capacity of the gateway device 2 . “HDD free space” is data indicating the condition of the free space of the HDD of the gateway device 2 . The "backup condition" may include the usage rate of the processor of the gateway device 2, and may include the resource environment such as the temperature or humidity of the memory, HDD, or processor of the gateway device 2. FIG.

"Backup method" is data indicating the backup method of the target data, and includes "backup period" and "backup cycle". "Backup period" is data indicating the data period of the data to be backed up. "Backup cycle" is data indicating a backup cycle, which is a cycle for backing up target data.

"Priority" is data indicating the priority of the target data, and the higher the priority of the target data, the more preferentially the backup destination gateway device 2 is determined. For example, "priority" is represented by a number from 1 to 5, and the smaller the value, the higher the priority.

In the setting data shown in FIG. 4, the data type of the target data with ID D0001 is temperature and the data name is room temperature, and the data type of the target data with ID D0002 is humidity, and the data name is indoor humidity.

In the setting data shown in FIG. 4, for the target data whose IDs are D0001 and D0002, a memory free space of "1 GB or more" and an HDD free space of "50 GB or more" are set as backup conditions, and a backup method is set as a backup method. A period of "1 hour" and a backup cycle of "3 minutes" are set. "1 GB or more" indicates that the memory free space is 1 GB or more, and "50 GB or more" indicates that the HDD free space is 50 GB or more.

Although not shown in FIG. 4, the setting data includes data of different combinations of backup conditions and backup methods for the same target data. For example, for the target data whose ID is D0002, in addition to the data shown in FIG. 3 minutes” is included.

The backup method determination unit 40 determines the backup method and backup destination for each target data, which is the data to be backed up, based on the setting data and the resource data. The backup method determining unit 40 selects the gateway devices 2 that satisfy the backup conditions defined by the setting data in order of priority in the setting data, and determines the backup method for each gateway device 2 .

The backup method determination unit 40 causes the method data storage unit 32 to store the determined backup method for each target data and the method data including each data of the backup destination. The backup method determination unit 40 determines the backup method and backup destination for each target data, for example, when the backup method determination timing arrives at a preset cycle. For example, the backup method determination unit 40 can shorten the arrival cycle of the backup method determination environment timing as the probability of _a disaster occurring in the region where the cloud environment 8-1 in which the server _5-1 is constructed increases. can. For example, if the target of monitoring and control is a river, the higher the water level of the river, the higher the possibility of a disaster occurring.

In addition, the backup method determination unit 40 can determine the gateway device 2 as the backup destination of the target data to be the gateway device 2 that does not transmit the measurement data corresponding to the target data. The measurement data corresponding to the target data is, for example, when the target data is intermediate data or processed data obtained from the measurement data transmitted from the monitoring control device ₁₁₁ or the measurement data transmitted from the monitoring control device ₁₁₁ . , are measurement data transmitted from the monitoring control device ₁₁₁ . In this case, the backup method determining unit 40 sets the gateway device 2 _other than the gateway device 21 as the backup destination of the target data.

In addition, when the backup method determination unit 40 cannot store all of the backup data in the plurality of gateway devices 2 due to insufficient free space in the HDDs of the plurality of gateway devices 2, the backup method determination unit 40 Data can be preferentially targeted for backup, and target data with low importance can be excluded from backup.

In addition, the backup method determination unit 40 determines the backup method and backup destination for each target data so that the same target data is backed up to different gateway devices 2 when the HDDs of the plurality of gateway devices 2 have sufficient free space. can also decide.

The backup execution unit 41 stores the backup data in the backup destination gateway device 2 determined by the backup method determination unit 40 using the backup method determined by the backup method determination unit 40 .

For example, the backup execution unit 41 acquires data for the backup period defined by the backup method determined by the backup method determination unit 40 from the monitoring control data storage unit 30 as target data. The backup executing unit 41 transmits the acquired target data to the backup destination gateway device 2 via the communication unit 20 , thereby causing the backup destination gateway device 2 to store the acquired target data.

The backup executing unit 41 repeatedly acquires the target data from the monitoring control data storage unit 30 at the backup cycle defined by the backup method determined by the backup method determining unit 40, and stores the acquired target data in the backup destination gateway device 2. be memorized. As a result, the target data in the gateway device 2 is updated to new data at the backup cycle defined by the backup method.

In addition, when the backup method and the backup destination are changed by the backup method determination unit 40, the backup execution unit 41 stores the target data in the changed backup destination gateway device 2 using the changed backup method.

In addition, the backup execution unit 41 transmits backup data to the gateway device 2 during a period when the information amount of the control data from the monitoring control processing unit 24 to the plurality of monitoring control devices 1 via the gateway device 2 exceeds the threshold value. can be stopped.

The setting data generation unit 27 generates setting data in a setting mode selected from the first setting mode and the second setting mode. The setting data generation unit 27 causes the setting data storage unit 31 to store the generated setting data. The first setting mode is a mode for generating setting data based on general setting data. The second setting mode is a mode for generating setting data based on past setting data. Note that the setting mode is set based on a setting request from the client device 3, for example.

First, the first setting mode will be explained. The setting data generating section 27 generates setting data based on the general setting data stored in the general setting data storage section 33 . The general setting data stored in the general setting data storage unit 33 is data including method data including data indicating a backup method and condition data indicating backup conditions for each data type.

FIG. 5 is a diagram showing an example of general setting data stored in a general setting data storage unit according to the first embodiment. As shown in FIG. 5, the general setting data stored in the general setting data storage unit 33 includes "tag ID", "tag name", "backup condition", "backup method", and "priority" as data types. data contained in each

"Tag ID" is identification data unique to each tag, and "tag name" is data indicating the name of the tag. A tag is set for each data type. "Tag name" includes data indicating the name of the data type as the name of the tag.

The "backup conditions", "backup method" and "priority" of the general setting data are the same as the "backup conditions", "backup method" and "priority" of the setting data shown in FIG.

For example, the setting data generation unit 27 determines the data type of each target data included in the monitoring control data stored in the monitoring control data storage unit 30, and based on the determined data type, sets backup conditions and conditions for each target data. Generate configuration data that includes data indicating how to back up.

For example, when the data type of the target data included in the monitoring control data is temperature, the setting data generated by the setting data generation unit 27 is data indicating the backup conditions associated with the ID "T0001" shown in FIG. and data indicating the backup method.

In this way, since the setting data generation unit 27 generates setting data based on the general setting data and the monitoring control data, at least part of the monitoring control data handled by the monitoring control system 100 Backup settings are made automatically. Therefore, in the monitoring and control system 100, by executing the first setting mode, it is possible to shorten the work time for setting the backup.

Next, the second setting mode will be explained. The setting data generation unit 27 generates setting data based on the past setting data stored in the past setting data storage unit 34 . The past setting data stored in the past setting data storage unit 34 is the setting data generated in the past, and includes the setting data generated in the past by the supervisory control system 100 and the settings generated in the past by another supervisory control system. Contains at least one of the data. The past setting data storage unit 34 stores a plurality of past setting data.

For example, the setting data generation unit 27 generates setting data based on the past setting data stored in the past setting data storage unit 34 and the monitoring control data stored in the monitoring control data storage unit 30 . Specifically, the setting data generating unit 27 selects the monitoring control data similar to the monitoring control data stored in the monitoring control data storage unit 30 from among the plurality of past setting data stored in the past setting data storage unit 34. Determine the past setting data that has been set for

For example, the setting data generating unit 27 determines the past setting data having the most similar data type and the number of data for each data type among the plurality of past setting data. The setting data generation unit 27 stores the past setting data determined to be most similar in the setting data storage unit 31 as setting data for the monitoring control system 100 .

As described above, since the setting data generation unit 27 generates setting data based on the past setting data and the monitoring control data, all data of the monitoring control data handled by the monitoring control system 100 can be backed up. Settings are automatic. Therefore, in the monitoring and control system 100, by executing the second setting mode, the input operation at the time of backup setting is unnecessary.

The backup data acquisition unit 28 is used when the server 5 switches from the standby system to the active system. Specifically, when a failure occurs in the active server 5 and the standby system is switched to the active system, the backup data acquisition unit 28 acquires a plurality of backup data distributed and stored in the plurality of gateway devices 2 . obtained from the gateway device 2 of the For example, the backup data acquisition unit 28 acquires backup data from each gateway device 2 via the communication unit 20 by transmitting a backup data transmission request to each gateway device 2 from the communication unit 20 . The backup data acquisition unit 28 stores the acquired backup data in the monitoring control data storage unit 30 as monitoring control data.

Next, processing by the gateway device 2 will be explained using a flowchart. 6 is a flowchart illustrating an example of processing by the gateway device according to the first embodiment; FIG.

As shown in FIG. 6, the data transmission/reception processing unit 12 of the gateway device 2 determines whether data addressed to another device has been received by the communication unit 10 or 11 (step S10). When the data transmission/reception processing unit 12 determines that data addressed to another device has been received (step S10: Yes), the data transmission/reception processing unit 12 transmits data addressed to the other device received by the communication unit 10 or 11 to the other device. A relay process of transferring via the communication unit 11 or the communication unit 10 is performed (step S11).

The resource data transmission processing unit 13 of the gateway device 2, when the processing of step S11 is completed, or when it is determined that the data addressed to another device has not been received (step S10: No), at the resource data transmission timing It is determined whether or not it has become (step S12).

In the processing of step S12, the resource data transmission processing unit 13, for example, when the communication unit 11 receives a resource transmission request transmitted from the server 5 at the backup cycle determined by the server 5, the resource data transmission timing is reached. I judge that. Note that when the backup cycle information determined by the server 5 is transmitted from the server 5 and received by the gateway device 2 , the resource data transmission processing unit 13 transmits resource data based on the backup cycle information transmitted from the server 5 . It is determined that the data transmission timing has come.

When the resource data transmission processing unit 13 determines that it is time to transmit the resource data (step S12: Yes), it generates resource data indicating the state of the resources of the gateway device 2 (step S13). Then, the resource data transmission processing unit 13 transmits the resource data generated in step S13 to the server 5 via the communication unit 11 (step S14).
