(First embodiment)
With reference to FIG. 1, a plant operation support system 1 according to a first embodiment of the present disclosure will be described. The plant operation support system 1 is a system used to support the operation of any plant that sequentially performs a plurality of processes on an object, such as a water treatment plant. The plant operation support system 1 includes an information processing device 10 and a terminal device 20. Although one information processing device 10 and one terminal device 20 are illustrated in FIG. 1, the plant operation support system 1 can include any number of information processing devices 10 and terminal devices 20.

The information processing device 10 is any computer such as a PC (Personal Computer), a smartphone, a tablet terminal, or a server. The information processing device 10 is installed, for example, in a central control room of a plant, but is not limited thereto and can be installed in any location. The information processing device 10 can communicate with the terminal device 20 and the plant equipment 30 via a network 40 including, for example, the Internet or a LAN (Local Area Network). The terminal device 20 is any computer used by a plant worker, such as a PC, a smartphone, a tablet terminal, a wearable terminal, or the like.

Each plant equipment 30 is any equipment used to perform one or more processes in a plant. For example, the plant equipment 30 may include any structure used to implement the process, field equipment, a control device such as a PLC (Programmable Logic Controller) that controls the field equipment, and any data related to the process (hereinafter also referred to as "process data"). ), a communication device connected to the network 40, and the like. However, the configuration of the plant equipment 30 is not limited to this example, and for example, a configuration that further includes a storage device or the like that temporarily stores the detected values of the sensors is also possible.

For example, FIG. 2 is a diagram showing a specific example of each plant equipment 30 provided in a water treatment plant. In the specific example of FIG. 2, the structures of each plant equipment 30 are illustrated as a water receiving well, a mixing basin, a floc formation basin, a settling basin, a sand filtration basin, a water purification basin, and a water distribution basin. Note that in FIG. 2, illustration of components other than the structures of each plant equipment 30 (for example, field equipment, control devices, sensors, etc.) is omitted. Also, for example, process data on a mixing pond used to carry out a chemical injection process may include, for example, data indicating the injection rate of a flocculant. Also, for example, process data on a settling tank used to perform a sedimentation and flocculation process may include data indicating the turbidity of water in the settling tank. Also, for example, process data on a sand filter used to implement a filtration process may include data indicating the frequency of cleaning of the filter sand layer. However, the process carried out using each plant equipment 30 and the process data in each plant equipment 30 are not limited to the specific example, and can be arbitrarily determined depending on the plant to which it is applied.

(Summary of the first embodiment)
Here, the outline of the first embodiment will be explained, and the details will be described later.

When the information processing device 10 detects the occurrence of an event that suggests an abnormality in the plant (for example, an event in which a value detected by a sensor installed in the plant equipment 30 of process data exceeds an allowable upper limit), the information processing device 10 detects the event. In addition to outputting an alarm indicating the occurrence of the abnormality, it also outputs confirmation work information regarding confirmation work to determine whether or not the abnormality has actually occurred (for example, whether or not the sensor is measuring correctly). The "confirmation work information" is information indicating the content of the confirmation work, but is not limited thereto, and may include any information related to the confirmation work, such as information instructing a worker to perform the confirmation work.

Subsequently, when the information processing device 10 obtains a confirmation result that the abnormality has actually occurred, the information processing device 10 obtains plant information regarding the plant, and performs work on one or more plant equipment 30 based on the plant information. Determine. Particularly in this embodiment, the plant information includes first information and second information described below, and the work includes first work and second work described below.

Specifically, the information processing device 10 first outputs at least one first question information, and acquires the worker's answer to the at least one first question information as the first information included in the plant information. . The "first question information" is question information for determining the primary countermeasure for an abnormality occurring in the plant. Typically, the primary countermeasure for an abnormality in a plant is implemented in a later process than the process in which the abnormality is currently occurring, thereby reducing the negative effects of the abnormality (for example, the product that has undergone the last process in the plant). quality deterioration, etc.). Therefore, in order to determine the primary countermeasure for the abnormality, the first question information is, for example, the current state of one or more plant equipment 30 that implements a process subsequent to the process in which the abnormality is currently occurring (for example, The information may include questions for confirming (process data, etc. of processes performed in the plant equipment 30). In such a case, the first information includes information indicating the current state of one or more plant equipment 30 that implements a process subsequent to the process in which the abnormality is currently occurring. However, the contents of the first question information and the first information are not limited to this example, and may be any question information and its answer for determining the primary countermeasure.

Subsequently, the information processing device 10 determines a first work as a primary countermeasure for the abnormality based on the acquired first information, and outputs first work information regarding the first work. In particular, in the present embodiment, the "first work" is a work that reduces the negative impact of the abnormality in a process that is later than the process in which the abnormality is actually occurring, and This is also done for one or more plant facilities 30 that carry out subsequent processes. However, the first work is not limited to this example, and may be any work that serves as a primary countermeasure for an abnormality. In addition, "first work information" is information indicating the content of the first work, but is not limited to this, and may include any information related to the first work, such as information instructing the worker to perform the first work. May include.

Subsequently, the information processing device 10 outputs at least one second question information, and acquires the worker's answer to the at least one second question information as second information included in the plant information. "Second question information" is question information for determining secondary countermeasures for abnormalities occurring in the plant. Typically, secondary countermeasures for an abnormality in a plant are required to alleviate or eliminate the abnormality itself by implementing it in the process where the abnormality is currently occurring or in a process preceding the process. . Therefore, in order to determine secondary countermeasures for an abnormality, the second question information is used, for example, to determine the current status of the process in which the abnormality is currently occurring or one or more plant equipment 30 that implements a process subsequent to the process. It may also include the content of a question to confirm the status. In such a case, the second information includes the current state of one or more plant equipment 30 that implements the process in which the abnormality is currently occurring or the process preceding the process. However, the contents of the second question information and the second information are not limited to this example, and may be any question information and its answer for determining secondary measures. Note that when the plant operation support system 1 is applied to a water treatment plant that processes water from a water source, the plant information includes current weather information of the area where the plant and/or the water source is located, and water source information regarding the water source (for example, (information indicating water quality such as pH or turbidity). In such a case, for example, the second question information may further include question content for confirming current weather information of the area where the plant and/or water source is located and water source information regarding the water source.

Then, the information processing device 10 determines a second work as a secondary countermeasure for the abnormality based on the acquired second information, and outputs second work information regarding the second work. In particular, in this embodiment, the "second work" is a work to alleviate or eliminate the abnormality in the process in which the abnormality is actually occurring or in a process preceding the process, where the abnormality is actually occurring. The process is carried out for one or more plant facilities 30 that carry out a process or a process preceding the process. However, the second work is not limited to this example, and may be any work that serves as a secondary countermeasure against an abnormality. Further, "second work information" is information indicating the content of the second work, but is not limited to this, and may include any information related to the second work, such as information instructing the worker to perform the second work. May include.

To explain a specific example of the operation of the information processing device 10 described above, for example, in the water treatment plant shown in FIG. When the occurrence of an event in which the detected value is higher than the permissible upper limit) is detected, an alarm indicating the occurrence of the event is issued (e.g., an alarm stating that the turbidity of the sedimentation basin may be higher than the permissible upper limit). is output, as well as confirmation work information related to the work to confirm whether or not turbidity abnormality in the sedimentation tank is actually occurring (for example, the work content "confirm whether the turbidity sensor of the sedimentation tank is measuring correctly") or work instruction information such as "Please check whether the turbidity sensor of the sedimentation tank is measuring correctly" is output.

When a confirmation result is obtained that turbidity abnormality in the sedimentation tank is actually occurring (for example, a confirmation result that "the turbidity sensor is measuring correctly"), the primary countermeasure for the turbidity abnormality in the sedimentation tank is determined. At least one first question information (for example, "Is the rising trend of head loss in the sand filter pond a normal value?") is output, and the worker's answer to the at least one first question information is output. (For example, an answer such as "the rising speed of head loss is higher than normal") is acquired as the first information included in the plant information. Next, based on the acquired first information, the first task (for example, "increasing the frequency of cleaning the filter sand layer in the sand filter basin higher than the normal value") is carried out as a primary countermeasure for the turbidity abnormality in the sedimentation basin. The first work information related to the first work (for example, information indicating the work content of "increasing the cleaning frequency of the filter sand layer in the sand filter pond higher than the normal value", or "the cleaning frequency of the filter sand layer in the sand filter pond") Work instruction information such as "Please raise the value higher than the normal value" is output. By having the worker perform the first work based on the first work information, primary measures can be taken to reduce the adverse effects of the abnormality in subsequent processes even if the abnormality continues.

Furthermore, at least one second question information for determining secondary countermeasures for turbidity abnormality in the settling basin (for example, "Is the turbidity of the raw water taken into the receiving well higher than on a clear day due to rain?" " question information) is output, and the worker's answer to the at least one second question information (for example, "The turbidity of the raw water is higher than on a clear day due to rain") is included in the plant information. This information is acquired as second information. Next, based on the acquired second information, a second task (for example, "increase the flocculant injection rate in the mixing basin to a higher rate than on a clear day") is determined as a secondary countermeasure for the turbidity abnormality in the settling basin. 2nd work information related to the second work (for example, information indicating the work contents such as "determine the appropriate value of the flocculant injection rate in the mixing pond using a jar test and change the injection rate to the appropriate value") Perform a test to determine the appropriate value for the flocculant injection rate in the mixing pond, and change the injection rate to the appropriate value.'' Work instruction information such as "Please change the injection rate to the appropriate value" is output. When the worker performs the second work based on the second work information, secondary measures are taken to alleviate or eliminate the abnormality that is currently occurring.

As described above, according to the first embodiment, when the occurrence of an event suggesting an abnormality in the plant is detected, an alarm is first output, so that the operator can quickly recognize the occurrence of the event. Furthermore, even though no abnormality has actually occurred, for example, there is a possibility that a sensor installed in the plant equipment 30 may malfunction due to a failure and an abnormal value may be erroneously detected. According to this method, since confirmation work information is output, it is possible to prompt the worker to confirm whether or not the abnormality is actually occurring. In addition, since the output of the first work information prompts the worker to perform the first work, even if the worker does not necessarily have sufficient experience and skills, the system can perform the work in a process subsequent to the process in which the abnormality is occurring. It becomes possible to implement primary measures to reduce the negative effects of abnormalities. In addition, in order to further encourage the worker to perform the second work by outputting the second work information, even if the worker does not necessarily have sufficient experience and skills, it is possible to use the second work to alleviate or eliminate the abnormality that is currently occurring. The following measures can be implemented.

Furthermore, the communication unit 11 includes a communication interface that communicates with each of the display device 50 and the input device 60. Here, the display device 50 is any display such as a liquid crystal display or an OEL (Organic Electro-luminescence) display. The input device 60 is any input interface that accepts operations by a user, such as a keyboard or a mouse.

The storage unit 12 is one or more memories. In this embodiment, the "memory" is, for example, a semiconductor memory, a magnetic memory, or an optical memory, but is not limited to these and can be any memory. Each memory included in the storage unit 12 functions as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 12 is built in, for example, the information processing device 10, but a configuration in which it is externally connected to the information processing device 10 via an arbitrary interface is also possible.

Control unit 13 includes one or more processors. In this embodiment, the "processor" is a general-purpose processor, a dedicated processor specialized for specific processing, or the like, but is not limited to these and can be any processor. The control unit 13 controls the operation of the information processing device 10 as a whole. Details of the operation of the information processing device 10 will be described later.

(Software configuration of information processing device)
The software configuration of the information processing device 10 will be described with reference to FIG. 3. One or more programs used to control the operation of the information processing device 10 are stored in the storage unit 12. When the one or more programs are read by the control unit 13, the information processing device 10 is configured to include a question storage unit 1301, a detection unit 1303, an alarm output unit 1304, a confirmation work output unit 1305, a confirmation result acquisition unit 1306, and a question output unit. 1307, acquisition means 1308, determination means 1309, and output means 1310.

The question storage unit 1301 is a unit for storing a plurality of question information in the storage unit 12. In this embodiment, the question storage unit 1301 stores a plurality of first question information and a plurality of second question information in the storage unit 12. Details will be explained below.

First, when it is assumed that a certain abnormality has occurred in a plant, as a primary countermeasure for the abnormality, multiple candidates for the first work (hereinafter also referred to as "first work candidates") are considered according to the state of the plant. It will be done. The plurality of first question information is used to determine an appropriate first work as a first countermeasure based on the current state of the plant from among a plurality of first work candidates when the abnormality in question actually occurs in the plant. It will be done.

Specifically, the question storage means 1301 stores a plurality of pieces of first question information in the storage unit 12 for each abnormality that is assumed to occur in the plant. Further, the question storage unit 1301 further stores in the storage unit 12 information indicating a plurality of first work candidates according to the answers to the plurality of first question information. For example, if three pieces of first question information are stored in association with a certain abnormality, each of which can be answered by a worker with Yes or No, up to eight pieces of first question information can be stored depending on the answer pattern of the three pieces of first question information. Information indicating work candidates can be stored. However, the mode of answering the first question information is not limited to the mode of answering Yes or No, for example, the mode of responding by selecting an arbitrary number of options from two or more options, or the mode of responding by selecting a numerical value. You can decide how you want to respond.

The content of each first question information, the content of each first work candidate, and the correspondence relationship between the answers to the plurality of first question information and each first work candidate are, for example, plant engineer, process engineer, or skilled worker. However, it is not limited to this example, and can be arbitrarily determined depending on the plant to which it is applied.

In addition, when it is assumed that a certain abnormality has occurred in a plant, for example, the same abnormality may occur as a result of multiple different factors, so as a secondary countermeasure for the abnormality, A plurality of candidates for the second work (hereinafter also referred to as "second work candidates") can be considered depending on the cause of the occurrence. The plurality of second question information is used to determine the appropriate second work as a secondary countermeasure based on the current state of the plant from among the plurality of second work candidates when the relevant abnormality actually occurs in the plant. used.

Specifically, the question storage means 1301 stores a plurality of pieces of second question information in the storage unit 12 for each abnormality that is assumed to occur in the plant. Further, the question storage unit 1301 further stores in the storage unit 12 information indicating a plurality of second work candidates according to the answers to the plurality of second question information. For example, if three pieces of second question information that can be answered by the worker with Yes or No are stored in association with a certain abnormality, up to eight pieces of second question information can be stored depending on the answer pattern of the three pieces of second question information. Information indicating work candidates can be stored. However, the mode of answering the second question information is not limited to the mode of answering Yes or No. For example, the mode of answering by the worker selecting an arbitrary number of options from two or more options, or the mode of answering by the worker choosing a numerical value You can decide how you want to respond.

The content of each second question information, the content of each second work candidate, and the correspondence relationship between each cause of abnormality estimated from the answers to the plurality of second question information and each second work candidate are, for example, It is determined by a plant engineer, a process engineer, or a skilled worker, but is not limited to this example, and can be arbitrarily determined depending on the plant to which it is applied.

Detection means 1303 is means for detecting the occurrence of an event that suggests an abnormality in the plant. Specifically, the detection means 1303 acquires detection values of process data by various sensors provided in each plant equipment 30 from each plant equipment 30 via the network 40 and communication unit 11 . The detection means 1303 detects, for example, an event in which the detected value of process data in a certain plant equipment 30 is an abnormal value in comparison with a predetermined standard (for example, the turbidity detected by a turbidity sensor of a sedimentation tank in a water treatment plant If an event in which the temperature is higher than the allowable upper limit) occurs, it is determined that an event indicating an abnormality in the plant equipment 30 (for example, abnormal turbidity in a sedimentation tank) has been detected. However, the event that suggests an abnormality in the plant is not limited to this specific example and can be arbitrarily determined. For example, the above-mentioned "event in which the detected value of the process data is an abnormal value in comparison with a predetermined standard" is an example of an event in which the detected value is within the permissible range (acceptable numerical range) but not within the recommended range. It may also be an event that the value does not fall within a desirable numerical range. Therefore, an "abnormality in the plant" may be a relatively serious abnormality that is unacceptable, or a relatively minor abnormality that is acceptable but undesirable.

The alarm output unit 1304 is a unit that outputs an alarm indicating the occurrence of the event when the detection unit 1303 detects the occurrence of the event. Specifically, the alarm output unit 1304 transmits a command to output an alarm indicating the occurrence of the event to, for example, the display device 50 and/or the worker's terminal device 20, and outputs the alarm on the screen and/or in the voice. Output with .

The confirmation work output means 1305 is a means for outputting confirmation work information regarding the work of checking whether or not the abnormality has actually occurred, when the occurrence of the above event is detected by the detection means 1303. Specifically, the storage unit 12 stores in advance information indicating the corresponding confirmation work for each event that can be detected by the detection means 1303. The confirmation work output means 1305 extracts the confirmation work corresponding to the event detected by the detection means 1303 from the storage unit 12 . Then, the confirmation work output means 1305 transmits an output command of confirmation work information regarding the extracted confirmation work to, for example, the display device 50 and/or the worker's terminal device 20, and outputs the confirmation work information on the screen and/or in the voice. Output with . Note that in this embodiment, a configuration in which the confirmation work output means 1305 is not provided is also possible. In such a case, the operator may perform confirmation work as appropriate in response to the warning output by the warning output means 1304.

The confirmation result acquisition means 1306 is a means for acquiring a confirmation result as to whether or not the above-mentioned abnormality is actually occurring. Specifically, the confirmation result acquisition unit 1306 acquires information indicating the confirmation result by the worker from the worker's terminal device 20 via the network 40 and the communication unit 11 or via the input device 60.

Question output means 1307 is means for outputting at least one piece of question information. In this embodiment, the question output means 1307 outputs at least one first question information and at least one second question information. Details will be explained below.

Specifically, the question output unit 1307 selects at least one piece of question information from among a plurality of pieces of question information associated with the abnormality that has been confirmed to have actually occurred. Then, the question output means 1307 transmits an output command of the selected at least one question information to, for example, the display device 50 and/or the worker's terminal device 20, and outputs the at least one question information on the screen and/or the worker's terminal device 20. Or output it as audio.

Note that any method can be adopted to select and output at least one question information from among a plurality of question information associated with an abnormality that has been confirmed to have actually occurred. For example, the question output unit 1307 may select and output the plurality of question information (that is, all the question information associated with the abnormality that has been confirmed to have actually occurred).

Alternatively, the question storage unit 1301 may further store, in the storage unit 12, the degree of association with the corresponding abnormality for each of the plurality of pieces of question information. The degree of association between the question information and each abnormality may be determined in advance by, for example, a plant engineer, a process engineer, or a skilled worker, or may be determined and updated based on the past operation history of the plant. Then, the question output means 1307 selectively outputs only each piece of question information whose degree of association with the abnormality is equal to or higher than a threshold value, from among the plurality of question information associated with the abnormality confirmed to have actually occurred. You may. Alternatively, when outputting at least one question information, the question output means 1307 may output each question information whose degree of association with the abnormality is equal to or higher than a threshold value and each question information whose degree of association with the abnormality is less than the threshold value. . Specifically, when outputting each question information in a distinguishable manner according to the degree of relevance, for example, each question information whose degree of relevance is greater than or equal to a threshold value is output before each question information whose degree of relevance is less than the threshold value. Alternatively, each question information whose degree of relevance is above a threshold value may be outputted more prominently than each question information whose degree of relevance is less than a threshold value (for example, by increasing the font size when outputting to the screen. , or increase the volume when outputting audio). However, the specific output mode of each question information according to the degree of relevance is not limited to this example, and can be arbitrarily determined.

Note that the question output means 1307 outputs at least one second question information at the same time as outputting the at least one first question information or after outputting the at least one first question information. According to the configuration in which the second question information is output after the output of the first question information, for example, the worker is first prompted to take the first measure, and then the second question is asked to determine the second measure. Since responses to information can be prompted, primary measures can be implemented quickly.

The acquisition means 1308 is means for acquiring plant information regarding the plant. Specifically, the acquisition means 1308 performs an operation on at least one question information outputted by the question output means 1307 from the worker's terminal device 20 via the network 40 and the communication unit 11 or via the input device 60. The answer of the person is acquired as part of the plant information (first information or second information).

The determining means 1309 is means for determining work to be performed on one or more plant equipment 30 based on the plant information acquired by the acquiring means 1308. Specifically, the determining means 1309 selects the worker's first information included in the acquired plant information from among the plurality of first work candidates associated with the abnormality that is confirmed to have actually occurred. The first work candidate according to the answer is determined as the first work. In addition, the determining means 1309 is configured to respond to the worker's answer, which is the second information included in the acquired plant information, from among the plurality of second work candidates associated with the abnormality that has been confirmed to have actually occurred. The second work candidate is determined as the second work.

Note that if the content of the work candidate (here, the first work candidate or the second work candidate) includes a variable (for example, the amount of operation to be performed on the plant equipment 30), the determining means 1309 The value of the variable is determined based on the information (here, the first information or the second information). For example, if the job candidate is "Please set the cleaning frequency of the filter sand layer in the sedimentation basin to [variable The value of the variable X can be determined by extracting it from the plant information and substituting it into the formula. However, the determination of variables included in the identified work candidates is not limited to this specific example, and any method can be adopted.

The output means 1310 is a means for outputting work information regarding the work determined by the determining means 1309. Specifically, the output unit 1310 transmits a command to output work information to, for example, the display device 50 and/or the worker's terminal device 20, and causes the first instruction information to be output on the screen and/or in voice. .

In addition to the above-mentioned means 1301 to 1310, the control unit 13 includes means for executing any processing that can be executed by a processor in general (for example, means for executing general arithmetic processing and time measurement processing, etc.). It is also possible to further function as

(Operation of information processing device)
The operation of the information processing device 10 according to the first embodiment will be described with reference to FIG. 4.

Step S100: The question storage means 1301 stores a plurality of question information (here, a plurality of first question information and a plurality of second question information) in the storage unit 12.

In detail, as described above, the question storage means 1301 stores a plurality of pieces of first question information in the storage unit 12 for each abnormality that is assumed to occur in the plant, and also answers answers to the plurality of pieces of first question information. The storage unit 12 further stores information indicating a plurality of first work candidates corresponding to the first work candidates. Further, the question storage means 1301 stores a plurality of pieces of second question information in the storage unit 12 for each abnormality that is assumed to occur in the plant, and also stores a plurality of pieces of second question information in accordance with the answers to the plurality of second question information. Information indicating work candidates is further stored in the storage unit 12.

If it is determined that the occurrence of the event has been detected (step S101-Yes), the operation proceeds to step S102. On the other hand, if it is determined that the occurrence of the event has not been detected (step S101-No), the operation of step S101 is repeatedly executed.

Step S102: If it is determined in step S101 that the occurrence of the event has been detected (step S101-Yes), the alarm output means 1304 outputs an alarm indicating the occurrence of the event.

Step S103: The confirmation work output means 1305 outputs confirmation work information regarding the confirmation work to determine whether or not the abnormality has actually occurred. Note that in this embodiment, a configuration in which step S103 is omitted is also possible. In such a case, the operator performs confirmation work as appropriate in response to the warning in step S102.

Step S104: The confirmation result acquisition means 1306 determines whether the abnormality is actually occurring based on the confirmation result by the operator. If it is determined that the abnormality has actually occurred (step S104-Yes), the operation proceeds to step S105. On the other hand, if it is determined that the abnormality has not actually occurred (step S104-No), the operation ends.

Step S105: If it is determined in step S104 that the abnormality has actually occurred (step S104-Yes), the question output means 1307 outputs at least one first question information. Specifically, as described above, the question output unit 1307 outputs at least one piece of first question information among the plurality of pieces of first question information associated with the abnormality that has been confirmed to have actually occurred.

Step S106: The acquisition means 1308 acquires the first information included in the plant information. In detail, as described above, the acquisition means 1308 receives at least one question outputted by the question output means 1307 from the worker's terminal device 20 via the network 40 and communication unit 11 or via the input device 60. The worker's answer to one question information is acquired as first information.

The worker's answer to the second question information is acquired as second information.

Step S111: The determining means 1309 determines a second work as a secondary countermeasure for the abnormality based on the acquired second information.

Step S112: The output means 1310 outputs second work information regarding the determined second work.

As described above, according to the first embodiment, when the occurrence of an event suggesting an abnormality in the plant is detected, an alarm is first output, so that the worker can quickly recognize the occurrence of the event. can. Furthermore, even though no abnormality has actually occurred, for example, there is a possibility that a sensor installed in the plant equipment 30 may malfunction due to a failure and an abnormal value may be erroneously detected. According to this method, since confirmation work information is output, it is possible to prompt the worker to confirm whether or not the abnormality is actually occurring. In addition, since the output of the first work information prompts the worker to perform the first work, even if the worker does not necessarily have sufficient experience and skills, the system can perform the work in a process subsequent to the process in which the abnormality is occurring. It becomes possible to implement primary measures to reduce the negative effects of abnormalities. In addition, in order to further encourage the worker to perform the second work by outputting the second work information, even if the worker does not necessarily have sufficient experience and skills, it is possible to use the second work to alleviate or eliminate the abnormality that is currently occurring. The following measures can be implemented.

(Second embodiment)
A second embodiment of the present disclosure will be described with reference to FIG. 5. In the second embodiment, part of the software configuration and operation of the information processing device 10 differs from the first embodiment described above. As an overview, in the second embodiment, the output of question information and the acquisition of answers are omitted, the plant information includes third information, which will be described later, performance information, which will be described later, is stored, and This embodiment differs from the first embodiment described above in that the first work and the second work as the primary countermeasure and the secondary countermeasure are determined based on the third information and performance information.

Specifically, when the program stored in the storage unit 12 of the information processing device 10 is read by the control unit 13, the information processing device 10 is detected by the detection unit 1303, the alarm output unit 1304, the confirmation work output unit 1305, and the confirmation result. It functions as an acquisition means 1306, an acquisition means 1308A, a determination means 1309A, an output means 1310, and a performance storage means 1315. Among these, the acquisition means 1308A, the determination means 1309A, and the performance storage means 1315 are different from the first embodiment, and the other means are the same as in the first embodiment. Hereinafter, differences from the first embodiment will be mainly described in detail.

The track record storage unit 1315 is a unit for storing track record information indicating the past state of the plant in the storage unit 12. The performance information includes time-series data of the detection values of each sensor installed in each plant equipment 30, a time stamp when an event suggesting an abnormality in the plant occurred and data indicating the event, and one item depending on the occurrence of the event. It includes time-series data of countermeasure work performed on the above plant equipment 30. In other words, the performance information includes multiple groups each having a combination of an event that occurred in the past, the detection value of each sensor when the event occurred, and countermeasure work performed for the abnormality related to the event. include. Each group can be defined using any algorithm, such as a decision tree. Further, each group may be defined by, for example, machine learning, or may be defined manually. Specifically, the performance storage means 1315 receives the detection value and time stamp of each sensor periodically, for example, from each plant equipment 30 via the communication unit 11. Furthermore, the performance storage unit 1315 receives information indicating the content of countermeasure work performed on the plant equipment 30 and a time stamp from each plant equipment 30 or the worker's terminal device 20 via the communication unit 11, for example. Then, the performance storage means 1315 stores the received information, data indicating the event detected by the detection means 1303, and a time stamp as performance information. Note that the performance information is not limited to the above specific example, and can be arbitrarily determined depending on the plant. For example, when applying the plant operation support system 1 to a water treatment plant that processes water from a water source, the performance information includes time-series data of past weather information of the area where the plant and/or water source is located, and past weather information regarding the water source. It may further include time series data of water source information. For example, the performance storage means 1315 may acquire weather information from an external server (for example, a weather information distribution server, etc.) via the communication unit 11 and the network 40, or may acquire weather information from each plant equipment 30 or worker via the communication unit 11. By acquiring water source information from the terminal device 20 of , these can be accumulated as performance information.

The acquisition means 1308A is means for acquiring plant information regarding the plant. In detail, the acquisition means 1308A acquires current detection values of one or more sensors installed in each plant equipment 30, detection values in a predetermined period going back from the present (i.e., time series data of detection values in the predetermined period). ), and at least one of the parameters calculated using the detection values of the one or more sensors is acquired as third information included in the plant information, which is different from the first embodiment. Specifically, the acquisition unit 1308A receives the current detection value of each sensor from each plant equipment 30 via the communication unit 11. Alternatively, the acquisition unit 1308A extracts the detection value of each sensor in the predetermined period from the performance information stored in the storage unit 12. Alternatively, the acquisition unit 1308A calculates a predetermined parameter using the current detection value of each sensor or the detection value of each sensor in the predetermined period. The parameter is any parameter that can be calculated or estimated from the detected values of one or more sensors. For example, the parameter may be any index value related to the process that is calculated or estimated by substituting the detection values of multiple sensors into a predetermined formula, or the statistical value of the detection value of one sensor over a predetermined period (e.g. , average value, median value, etc.), but are not limited to these. Note that the third information is not limited to the above specific example, and can be arbitrarily determined depending on the plant. For example, when the plant operation support system 1 is applied to a water treatment plant that processes water from a water source, the third information may include current weather information of the area where the plant and/or water source is located (or weather information for the above-mentioned predetermined period). ) and current water source information regarding the water source (or time series data of the water source information in the predetermined period). For example, the acquisition unit 1308A can acquire weather information from an external server (for example, a weather information distribution server, etc.) via the communication unit 11 and the network 40, or acquire weather information from each plant equipment 30 or worker via the communication unit 11. Water source information can be acquired from the terminal device 20.

The determining means 1309A is means for determining work to be performed on one or more plant equipment 30 based on the plant information acquired by the acquiring means 1308A. Specifically, when the confirmation result acquisition means 1306 acquires a confirmation result that an abnormality has actually occurred, the determination means 1309A selects the third information included in the plant information acquired by the acquisition means 1308A and the actual performance. This embodiment differs from the first embodiment in that the work is determined based on the performance information stored in the storage unit 12 by the storage unit 1315. Specifically, for example, when the current detection value of each sensor is acquired as the third information, the determining means 1309A selects the current detection value of each sensor from among the plurality of groups included in the performance information. , and in which the same event as the event currently detected by the detection means 1303 has occurred. The determining means 1309A determines, among the countermeasure work included in the identified one or more groups, the work that reduces the negative impact of the abnormality in a process subsequent to the location where the abnormality occurs, and The work to be performed on the plant equipment 30 is determined as the first work. Further, the determining means 1309A determines whether, among the countermeasure work included in the identified one or more groups, the work is to alleviate or eliminate the abnormality in the process in which the abnormality is currently occurring or in a process preceding the process. Then, the work to be performed on one or more plant equipment 30 that implements the process in which the abnormality is currently occurring or the process preceding the process is determined as the second work.

(Operation of information processing device)
The operation of the information processing device 10 according to the second embodiment will be described with reference to FIG. 6.

Step S200: The track record storage unit 1315 stores track record information in the storage unit 12. As mentioned above, performance information includes multiple items each having a combination of an event that occurred in the past, the detection value of each sensor when the event occurred, and countermeasure work performed for the abnormality related to the event. Contains groups of.

Step S201: The detection means 1303 determines whether or not the occurrence of an event suggesting an abnormality in the plant has been detected. If it is determined that the occurrence of the event has been detected (step S201-Yes), the operation proceeds to step S202. On the other hand, if it is determined that the occurrence of the event has not been detected (step S201-No), the operation of step S201 is repeatedly executed.

Step S202: If it is determined in step S201 that the occurrence of the event has been detected (step S201-Yes), the alarm output means 1304 outputs an alarm indicating the occurrence of the event.

Step S203: The confirmation work output means 1305 outputs confirmation instruction information that instructs the operator to perform a confirmation work to determine whether or not the abnormality has actually occurred. Note that in this embodiment, a configuration in which step S203 is omitted is also possible. In such a case, the operator performs confirmation work as appropriate in response to the warning in step S202.

Step S204: The confirmation result acquisition unit 1306 determines whether the abnormality is actually occurring based on the confirmation result by the operator. If it is determined that the abnormality is actually occurring (step S204-Yes), the operation proceeds to step S205. On the other hand, if it is determined that the abnormality has not actually occurred (step S204-No), the operation ends.

Note that in this embodiment, for example, a configuration in which step S203 is omitted is also possible. In this case, instead of having an operator confirm the occurrence of an abnormality, for example, the current detection value of one or more sensors installed in each plant equipment 30 and the detection value over a predetermined period retroactively from the present are obtained, Based on the acquired detection value, it may be determined that an abnormality is actually occurring. Alternatively, if it is determined in step S202 that the occurrence of the event has been detected, steps S203 and S204 may be omitted and the process may proceed to step S205.

Step S205: If it is determined in step S204 that the abnormality has actually occurred (step S204-Yes), the acquisition means 1308A acquires the third information included in the plant information. In detail, the acquisition means 1308A acquires, for example, the current detection value of one or more sensors provided in each plant equipment 30, the detection value in a predetermined period going back from the present, and the detection value of the one or more sensors. At least one of the calculated parameters is acquired as third information.

Step S206: The determining means 1309A performs the first work as a primary countermeasure for the abnormality based on the third information acquired by the acquiring means 1308A and the performance information stored in the storage unit 12 by the performance storage means 1315. decide.

Step S207: The output means 1310 outputs first work information regarding the determined first work.

Step S208: The determining means 1309A performs a second operation as a secondary countermeasure for the abnormality based on the third information acquired by the acquiring means 1308A and the performance information stored in the storage unit 12 by the performance storage means 1315. Determine.

Step S209: The output means 1310 outputs second work information regarding the determined second work.

As described above, according to the second embodiment, the first work and the second work are determined based on the third information and performance information. There is no need to answer questions, and the burden on the worker can be reduced.

In addition, in 2nd Embodiment mentioned above, the example which utilized the plant operation support system 1 in order to support implementation of the primary countermeasure and secondary countermeasure for abnormality in a plant was demonstrated. However, the plant operation support system 1 can also be used, for example, to support plant operation during normal times, without assuming that an abnormality occurs in the plant. In such a case, the actual performance information includes time-series data of the detection values of each sensor installed in each plant equipment 30 during normal times, and work performed on the plant equipment 30 during normal times (for example, the operation of the plant during normal times). This includes time-series data of work to continue operations, maintenance and inspection work of plant equipment 30 during normal times, etc.). That is, the performance information includes a plurality of groups each having a combination of a work performed in the past and a detection value of each sensor when the work was performed. The determining means 1309A determines which task the worker should perform next in normal times, based on the third information acquired by the acquiring means 1308A and the performance information stored in the storage unit 12 by the performance storage means 1315. (hereinafter also referred to as "normal work"). Specifically, for example, when the current detection value of each sensor is acquired as the third information, the determining means 1309A selects the current detection value of each sensor from among the plurality of groups included in the performance information. Identify one or more groups that are similar to. The determining means 1309A determines the work included in the identified one or more groups as the normal work that the worker should perform next. Then, the output means 1310 outputs normal work information regarding the determined normal work. According to this configuration, it is possible to make the worker aware of the normal work to be performed next by outputting the normal work information, so that even the worker who does not necessarily have sufficient experience and skills can perform the normal operation of the plant. can be continued appropriately. Note that when using the plant operation support system 1 to support plant operation in normal times, various means related to abnormalities in the plant (detection means 1303, alarm output means 1304, confirmation work output means 1305, and confirmation result acquisition means) are used. 1306) can be omitted.

(Modified example of embodiment)
Further, a modification example that combines the first embodiment and the second embodiment described above is also possible. With reference to FIG. 7, an information processing device 10 according to a modification of the embodiment will be described. As an overview, the information processing device 10 according to the present modification determines the work to be performed on one or more plant equipment 30 based on the third information and performance information, as in the second embodiment, while also determining the work to be performed on one or more plant equipment 30 as described below. If the work cannot be determined based on the third information and performance information, the work is determined based on the first information and the second information as in the first embodiment.

Specifically, when the program stored in the storage unit 12 of the information processing device 10 is read by the control unit 13, the information processing device 10 is controlled by the question storage unit 1301, the detection unit 1303, the alarm output unit 1304, and the confirmation work output. It functions as means 1305, confirmation result acquisition means 1306, acquisition means 1308, determination means 1309, output means 1310, and performance storage means 1315. The following will mainly describe operations specific to this modification.

The acquisition means 1308 acquires the third information included in the plant information, similarly to the second embodiment described above. Note that the acquisition of the third information may be performed, for example, after the confirmation result acquisition means 1306 determines that an abnormality has actually occurred based on the confirmation result by the operator, and then the question output means 1307 outputs at least one first question information. However, it is not limited to this, and can be performed at any timing. In this modification, when the confirmation result acquisition means 1306 determines that an abnormality has actually occurred, the third acquisition means 1316 acquires the third information.

When the third information is acquired, the determining means 1309 attempts to determine the first work to be performed on one or more plant equipment 30 based on the third information and performance information. Specifically, for example, when the current detection value of each sensor is acquired as the third information, the determining means 1309 selects the current detection value of each sensor from among the plurality of groups included in the performance information. It is determined whether one or more groups that are similar to the above and in which the same event as the event currently detected by the detection means 1303 has occurred can be identified.
If one or more groups can be identified, the determining means 1309 reduces the negative impact of the abnormality in a process subsequent to the location where the abnormality occurs, among the countermeasure work included in the identified one or more groups. The work to be performed on the plant equipment 30 that implements the subsequent process is determined as the first work. In this way, when the first task can be determined based on the third information and performance information, the question output means 1307 outputs the first question information (step S105 described above) and the acquisition means 1308 acquires the first information ( Step S106) described above is omitted. On the other hand, if one or more groups cannot be identified (that is, the first task cannot be determined based on the third information and performance information), the operations from step S105 onward are similar to the first embodiment described above. is executed.

According to this configuration, when the work to be performed on the plant equipment 30 can be determined based on the third information and the performance information, the output of the first question information and the acquisition of the first information are omitted. There is no need for the operator to answer the first question information, and the burden on the operator can be reduced.

Note that in this modification, the second task can also be determined using the same method as the first task described above. Specifically, when one or more groups can be identified as described above, the second determining means 1313 determines whether the abnormality has actually occurred among the countermeasure work included in the identified one or more groups. Work to alleviate or eliminate the abnormality in the process in which the abnormality is currently occurring or in the process preceding the process, and is performed on the plant equipment 30 that implements the process in which the abnormality is currently occurring or the process preceding the process. The work is determined as the second work. On the other hand, if one or more groups cannot be identified (that is, if the second task cannot be determined based on the third information and performance information), the operations from step S109 onward are similar to the first embodiment described above. is executed. According to this configuration, when the second work can be determined based on the third information and performance information, the output of the second question information and the acquisition of the second information are omitted, so that the worker can There is no need to respond to information, and the burden on the worker can be reduced.

Further, in the above-mentioned modification, a specific example was given to explain the combination of the first embodiment and the second embodiment, but the operation mode related to the combination of both embodiments is not limited to the above-mentioned specific example. For example, a configuration is also possible in which the information processing device 10 can switch between the operation of the first embodiment and the operation of the second embodiment in response to the occurrence of an arbitrary trigger. For example, during normal times, the information processing device 10 determines the normal work that the worker should perform next based on the third information and performance information, similar to the second embodiment, but when an abnormality occurs, the information processing device 10 determines the normal work that the worker should perform next, as in the second embodiment. Similarly, it is also possible to determine the first work and the second work as the primary countermeasure and secondary countermeasure for the abnormality based on the first information and the second information.

It should therefore be noted that these variations and modifications are included within the scope of this disclosure. For example, the functions included in each means, each step, etc. can be rearranged so as not to be logically contradictory, and it is possible to combine or divide multiple means and steps into one. .

For example, a configuration in which the plant operation support system 1 includes a plurality of information processing devices 10 is also possible. Further, a configuration in which each component or each means of one information processing device 10 according to the embodiment is distributed and arranged in a plurality of devices that can communicate with each other is also possible.

Furthermore, in the embodiment described above, an example of the operation of the information processing apparatus 10 has been described with reference to FIGS. 4 and 6. However, a configuration is also possible in which some steps included in the operations described above or some operations included in one step are omitted within a logically consistent range. Furthermore, a configuration in which the order of a plurality of steps included in the above-described operation is changed within a logically consistent range is also possible.
