The status information may be status information included in the process information, for example. The status information of one record may include a plurality of status information.

  The external information table has external information associated with the date and time when each external information was generated or acquired.

  The monitoring device 40 is an information processing device that can communicate with the server 30. The monitoring device 40 includes an information acquisition unit 401, an operation information acquisition unit 402, a control unit 403, a condition storage unit 404, an information determination unit 405, a related information storage unit 406, and a display control unit 407.

The information acquisition unit 401 acquires all candidate information (external information). Then, the information acquisition unit 401 records the acquired candidate information in the candidate information storage unit 302 of the server 30.
The information acquisition unit 401 acquires text or image (still image or moving image) data as candidate information from, for example, a WEB site published on the Internet. The information acquisition unit 401 acquires recorded data as candidate information by recording a moving image of a television program and a television commercial broadcasted by, for example, terrestrial broadcasting or satellite broadcasting.
Candidate information is information indicated by a predetermined condition. The predetermined condition may be, for example, a condition indicating a WEB site from which data is acquired, a condition indicating acquired data, or another condition. . For example, when the predetermined condition is a condition of “information published by Japanese government offices”, the information acquisition unit 401 may provide information published by the Japanese government offices via the network. You may acquire all of. In this case, more specifically, a URL (Uniform Resource Locator) of each WEB site where information is published by a public office in Japan may be set as a predetermined condition. When a search keyword is set as a condition indicating acquired data, the information acquisition unit 401 selects all information related to the set search keyword from information published on the Internet or other networks. May be acquired as candidate information. The information acquisition unit 401 may record moving images of television programs and television commercials that are broadcast by terrestrial broadcasting or satellite broadcasting. In this case, the recorded moving image data is recorded as candidate information. The information acquisition unit 401 may record moving images of all broadcasted TV programs and TV commercials, or the TV programs and TV commercial videos of time zones and channels indicated in predetermined predetermined conditions. Only images may be recorded. The information acquisition unit 401 may acquire an image (still image or moving image) captured by an imaging device installed in advance as candidate information. In this case, the URL of a WEB site from which an image can be acquired and the IP address of the imaging apparatus may be set as predetermined conditions.

  The operation information acquisition unit 402 acquires information input by the operator of the monitoring system 100 operating the input device 50 (hereinafter referred to as “operation information”). When the operation information acquisition unit 402 is connected to the input device 50 with a wired cable, the operation information acquisition unit 402 acquires operation information by acquiring an electrical signal via the wired cable. When the operation information acquisition unit 402 is connected to the input device 50 through short-range wireless communication such as Bluetooth (registered trademark), the operation information acquisition unit 402 acquires operation information by receiving a radio signal via the short-range wireless communication. . When the operation information acquisition unit 402 is connected to the input device 50 via a network, the operation information acquisition unit 402 acquires operation information by receiving data via the network.

  The control unit 403 controls the monitoring device 40. The control unit 403 controls the information determination unit 405 and the display control unit 407 based on the operation information acquired by the operation information acquisition unit 402, for example. For example, when the operation information acquired by the operation information acquisition unit 402 is information related to a scenario condition (described later), the control unit 403 registers the acquired scenario condition in the condition storage unit 404.

  The condition storage unit 404 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The condition storage unit 404 stores a scenario table. FIG. 3 is a diagram illustrating a specific example of the scenario table. The scenario table has a plurality of records. A record in the scenario table has a scenario ID and a scenario condition value. The scenario ID is scenario identification information represented by each record. The scenario condition indicates a condition set for the scenario represented by each record. The scenario conditions are a condition (hereinafter referred to as an “event condition”) representing an event that can occur in the equipment to be monitored or a monitored object (hereinafter referred to as “event condition”), and a condition that represents information to be collected regarding the event (hereinafter referred to as “collection condition”). And. When information including a character string set in the scenario condition is recorded in the candidate information storage unit 302, the information is recorded in the related information storage unit 406 as related information. Further, when an event indicated by the event condition of the scenario condition occurs, process information related to the event is recorded in the related information storage unit 406 as related information.

  In the example of FIG. 3, “typhoon”, “rain”, “pump and failure”, “flood”, and “water level and high” are set as the scenario conditions with the scenario ID “00001”. “And” included in the scenario condition indicates an AND condition, and does not indicate the character string itself of “and”. That is, the scenario condition “water level and high” is a condition indicating that two character strings “water level” and “high” are included. Of the candidate information, information including any of the keywords “typhoon”, “rain”, “pump and failure”, “flood”, and “water level and high” is recorded as related information. Further, when a predetermined character string (for example, “pump and failure”, “water level and high”) is set as the scenario condition, the character string is interpreted by the information determination unit 405 as an event condition. For example, the character string “pump and failure” is the value of various values used for determining whether or not the pump has failed in the monitoring device 40 when those values indicate the occurrence of a failure. Is recorded as related information. For example, the character string “water level and high” indicates that when the value indicating the water level exceeds a threshold value indicating abnormality, the value is recorded as related information. The association between the character string indicating each event condition and the specific content indicated by the event condition is registered in the information determination unit 405 in advance.

The information determination unit 405 determines whether information satisfying the scenario condition is recorded in the candidate information storage unit 302 for each scenario ID recorded in the condition storage unit 404. When information satisfying the scenario is recorded in the candidate information storage unit 302, the information determination unit 405 records the information as related information in association with the scenario ID in the related information storage unit 406.
When the search condition is acquired by the operation information acquisition unit 402, the information determination unit 405 acquires information related to the acquired search condition from the candidate information stored in the candidate information storage unit 302. The information determination unit 405 outputs the acquired related information to the display control unit 407 via the control unit 403. The acquired related information is displayed on the display device 60 by the display control unit 407. The search condition may be a keyword, identification information indicating a predetermined device, or information indicating a predetermined date and time or period. For example, when the search condition “apparatus ZZ between XX and YY three days ago” is acquired, the information determination unit 405 obtains process information between XX and YY three days ago among the process information of the apparatus ZZ. Read from the candidate information storage unit 302. Thereafter, the display control unit 407 displays an image based on this process information.

  The related information storage unit 406 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The related information storage unit 406 stores data of information determined as related information by the information determination unit 405. The related information storage unit 406 may be configured to store a related information table, for example.

  FIG. 4 is a diagram illustrating a specific example of the related information table. The related information table has a plurality of records. A record in the related information table has a scenario ID and related data values. In the related information table shown in FIG. 4, one record is registered for each scenario ID (for each scenario condition) registered in the scenario table. The scenario ID is scenario identification information represented by each record. The related data indicates data of related information determined to be related to the scenario represented by each record. For example, the related data in the record having the scenario ID “00001” is data of related information determined to satisfy the scenario condition of the scenario ID “00001”.

  The display control unit 407 controls display on the display device 60 according to the control of the control unit 403. For example, the display control unit 407 generates a screen to be displayed on the display device 60 and outputs the screen to the display device 60.

  The input device 50 is configured using an existing input device such as a keyboard, a pointing device (such as a mouse or a tablet), a button, or a touch panel. The input device 50 is operated by the operator when an operator's instruction is input to the monitoring device 40.

  The display device 60 is an image display device such as a CRT (Cathode Ray Tube) display, a liquid crystal display, or an organic EL (Electro Luminescence) display. The image displayed by the display device 60 is visually recognized by the operator.

  FIG. 5 is a specific example of a flowchart showing a flow of candidate information acquisition processing performed by the monitoring device 40. When the predetermined collection timing arrives (step S101—YES), the information acquisition unit 401 acquires candidate information according to a predetermined condition (step S102). The information acquisition unit 401 requests the server 30 to record the acquired candidate information in the candidate information storage unit 302 (step S103). The control unit 301 of the server 30 records candidate information in the candidate information storage unit 302 in response to a request from the information acquisition unit 401.

  FIG. 6 is a specific example of a flowchart showing a flow of candidate information deletion processing performed by the server 30. When the predetermined discard timing has arrived (step S201—YES), the control unit 301 determines whether or not the elapsed time since the recording of the candidate information recorded in the candidate information storage unit 302 exceeds the threshold value. (Step S202). When the elapsed period exceeds the threshold (step S202—YES), the control unit 301 deletes the candidate information from the candidate information storage unit 302 (step S203). On the other hand, when the elapsed period does not exceed the threshold (step S202—NO), the control unit 301 does not delete the candidate information from the candidate information storage unit 302. The control unit 301 executes the processing from step S202 on all candidate information recorded in the candidate information storage unit 302. When the process is completed for all candidate information (step S204—YES), the control unit 301 ends the deletion process.

  FIG. 7 is a specific example of a flowchart showing a flow of related information generation processing performed by the monitoring device 40. When the predetermined determination timing comes (step S301—YES), the information determination unit 405 determines a record to be processed among records registered in the scenario table of the condition storage unit 404. The information determination unit 405 determines whether there is candidate information satisfying the scenario condition of the record to be processed among the candidate information recorded in the candidate information storage unit 302 (step S302). When there is candidate information that satisfies the scenario condition (step S302—YES), the information determination unit 405 acquires the candidate information as related information. Then, the information determination unit 405 records the acquired related information in the related information storage unit 406 (step S303). On the other hand, the information determination unit 405 does not record candidate information that does not satisfy the scenario condition in the related information storage unit 406.

  The information determination unit 405 determines whether or not the processing from step S302 to step S304 has been executed for all candidate information for the scenario condition of the record to be processed (step S304). When unprocessed candidate information exists (step S304—NO), the information determination unit 405 executes the processing from step S302 to step S304 on the unprocessed candidate information. On the other hand, when there is no unprocessed candidate information (step S304—YES), the information determination unit 405 has performed the processing from step S302 to step S305 for all scenarios registered in the condition storage unit 404. (Step S305). When an unprocessed scenario exists (step S305-NO), the information determination unit 405 executes the processing from step S302 to step S305 for the scenario condition of the unprocessed scenario. On the other hand, when there is no unprocessed scenario (step S305—YES), the information determination unit 405 ends the determination process.

  By repeatedly executing the processes of FIGS. 6 and 7 at a predetermined timing, candidate information is recorded in the candidate information storage unit 302 of the server 30 only for a predetermined period represented by the threshold of the elapsed period. That is, candidate information that exceeds the threshold of the elapsed period is deleted from the candidate information storage unit 302. Further, even if the information exceeds the threshold of the progress information, the information determined by the information determination unit 405 as the related information is recorded in the related information storage unit 406. Therefore, even if the information exceeds the threshold of the progress information, the operator can refer to the related information. Further, all candidate information is accumulated in the candidate information storage unit 302 until a predetermined period elapses. Therefore, even if it is information that has already been difficult to obtain on the Internet etc. with past information, it is necessary to go back to the past and obtain necessary information as related information as long as the predetermined period has passed. It becomes possible to do. For example, when the operator operates the input device 50 to instruct to display the weather map 14 days ago and the process information 14 days ago, the display device 60 is displayed 14 days ago by the operations of the control unit 403 and the display control unit 407. Weather map and process information 14 days ago are displayed.

Then, the display control unit 407 displays a plurality of related information on the display device 60 in various modes. Therefore, it becomes possible to provide information that makes the determination easier for the operator.

  When the operator operates the input device 50 and inputs a search keyword, the control unit 403 passes the input search keyword to the display control unit 407. The display control unit 407 searches for the scenario ID of the relationship information having a high correlation with the search keyword. The display control unit 407 displays, for example, the relationship information associated with the scenario ID determined to have the highest correlation on the display device 60. This display may be performed, for example, in a manner as shown in FIGS. 8 to 12 or in another manner. By performing such processing, the operator can efficiently learn based on information related to past events.

  Regarding such effects, there are the following backgrounds. The number of skilled operators who have operated the plant has been decreasing year by year, and the lack of inheritance of plant know-how has become a problem. In the future, the opportunity for operators to acquire knowledge about the detailed level of each device that is becoming increasingly diverse due to automation and widening of the device tends to decrease. However, although most of the operations of the monitoring and control system that are currently implemented have a wide variety of information, the information that is actually provided to the operator is often simple and limited. For example, the failure or state of the equipment is displayed on the monitoring screen, but the cause and subsequent effects are not displayed. If the operator examines why the failure or condition occurred, the operator must manually retrieve the information. Therefore, it took a lot of time and labor. In addition, although it is a problem in recent years to provide an inexperienced operator with a place for learning and technology inheritance, in reality, information for effectively performing learning and technology inheritance is not provided. In response to such a problem, the monitoring system 100 according to the embodiment can provide related information to the operator in the above-described manner to improve the efficiency of learning and technology inheritance.

  According to at least one embodiment described above, an information determination unit 405 that determines and records related information from candidate information, and a display control unit 407 that displays the related information on the display device 60 can be provided to the operator. Thus, it is possible to provide information that makes judgment easier.

  FIG. 13 is a diagram illustrating a modification of the related information table. A record in the related information table shown in FIG. 13 has values of record ID, scenario ID, target period, and related data. In the related information table shown in FIG. 13, one record is registered for one case (for example, occurrence of failure or alarm) that satisfies the scenario conditions registered in the scenario table. The record ID indicates record identification information. The scenario ID indicates which scenario condition the case represented by each record is. The target period represents a date and time period of related data registered in each record based on the occurrence of the case represented by each record. The related data represents data of related information acquired regarding the case represented by each record.

  For example, in the record with the record ID “0000001”, based on the occurrence of a case (for example, a pump failure) that satisfies the scenario condition of the scenario ID “00001”, the relationship information obtained from the occurrence date and time for a predetermined time, Related information obtained until a predetermined time elapses from the date and time of occurrence is registered as related data. A period from a date and time that is a predetermined time later than the date and time of occurrence to a date and time when a predetermined time has elapsed from the date and time of occurrence is registered as the value of the target period. When the related information table is configured in this way, the display control unit 407 generates a screen based on the information of the same record. That is, any process flow information and external information displayed on one screen are created based on related data recorded in the related information storage unit 406 in association with the same record ID.

  Each functional unit provided in the server 30 and the monitoring device 40 may be provided in another device. For example, the information acquisition unit 401 may be included in the server 30 instead of being included in the monitoring device 40, or may be included in another device (for example, an information acquisition device) not described in the above embodiment. Also good. For example, the information determination unit 405 is not provided in the monitoring device 40 but may be provided in the server 30 or provided in another device (for example, an information determination device) that is not described in the rule embodiment. Also good. Further, the server 30 and the monitoring device 40 may be configured as an integrated device.

  You may make it implement | achieve the function of the monitoring apparatus 40 in embodiment mentioned above with a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program that holds a program for a certain period of time. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
