[0009] (First Embodiment) A memory control device according to one embodiment of this disclosure will be described below with reference to the drawings. The memory control device according to this embodiment is used, for example, in a plant monitoring system. The memory control device stores alarm information indicating failures or abnormalities in plant equipment. The user uses the various information stored in the memory control device to perform maintenance on the plant equipment.

[0010] Figure 1 is a schematic block diagram showing the system configuration of the plant monitoring system 1 according to the embodiment. As shown in Figure 1, the plant monitoring system 1 includes a first plant 10, a second plant 20, and a terminal device 30 (memory control device). In this embodiment, the first site A1 where the first plant 10 is located and the second site A2 where the second plant 20 is located are, for example, located at a distance from each other. The terminal device 30 is, for example, located at a remote location A3 that is separated from the first site A1 and the second site A2.

[0011] In this embodiment, the first plant 10 and the second plant 20 are, for example, a waste incineration plant, a power plant, or a cogeneration facility. Alternatively, the first plant 10 and the second plant 20 may be combustion facilities such as a stoker furnace, a melting furnace, an on-site gas turbine, an on-site gas engine, or a biomass facility. The first plant 10 comprises the first equipment 11. The second plant 20 comprises the second equipment 21. In this embodiment, the first equipment 11 and the second equipment 21 are, for example, the equipment that constitutes the plants described above. The first equipment 11 and the second equipment 21 may include, for example, boiler equipment, drainage equipment, cooling tower equipment, instrumentation air equipment, and decarbonization equipment.

[0012] In this embodiment, there may be multiple pieces of equipment. Specifically, in this embodiment, there may be multiple first pieces of equipment 11 in the first plant 10, and there may be multiple second pieces of equipment 21 in the second plant 20. For example, multiple boiler pieces of equipment may be provided in each of the first pieces of equipment 11 and the second pieces of equipment 21. For example, in the first piece of equipment 11, multiple pieces of the same equipment may be provided, or one different piece of equipment may be provided in each. In this embodiment, at least some of the components constituting the first equipment 11 and the components constituting the second equipment 21 are different. That is, for example, the first equipment 11 and the second equipment 21 do not have to have the same components or equipment. For example, the first equipment 11 may have a stoker furnace, while the second equipment 21 has a melting furnace. In this case, some of the components constituting the stoker furnace of the first equipment 11 and some of the components constituting the melting furnace of the second equipment 21 may be the same. Furthermore, in this case, the components constituting the stoker furnace of the first equipment 11 and the components constituting the melting furnace of the second equipment 21 do not have to be completely common. Also, for example, even if the first equipment 11 and the second equipment 21 have the same components, the number of such components may differ. For example, the first equipment 11 may have three boiler units, while the second equipment 21 has two boiler units.

[0013] As shown in Figure 1, the first plant 10 and the terminal device 30, and the second plant 20 and the terminal device 30 are connected to each other via a network 70. The network 70 may be a wireless communication network or a wired communication network. The network 70 may be configured using, for example, the Internet or a local area network (LAN). The network 70 may be configured by combining multiple networks.

[0014] Figure 2 is a schematic block diagram showing a specific example of the functional configuration of the terminal device 30. The terminal device 30 is configured using an information device such as a smartphone, a tablet, a personal computer, or a dedicated device. The terminal device 30 includes a communication unit 31, an input unit 32, a display unit 33, a memory unit 34, and a control unit 35.

[0015] The communication unit 31 is a communication device. The communication unit 31 may be configured as, for example, a network interface. The communication unit 31 performs data communication with other devices via the network 70 according to the control of the control unit 35. The communication unit 31 may be a device that performs wireless communication or a device that performs wired communication.

[0016] The input unit 32 is configured using an existing input device such as a keyboard, a pointing device (mouse, tablet, etc.), a button, or a touch panel. The input unit 32 is operated by the user when inputting the user's instruction to the terminal device 30. The input unit 32 may be an interface for connecting the input device to the terminal device 30. In this case, the input unit 32 inputs an input signal generated in response to the user's input in the input device to the terminal device 30. The input unit 32 may be configured using a microphone and a voice recognition device. In this case, the input unit 32 acquires an acoustic signal generated by the user's speech, recognizes the words spoken by the user, and inputs the string information of the recognition result to the terminal device 30. The voice recognition processing may be executed by the control unit 35. The input unit 32 may be configured in any manner as long as it can input the user's instruction to the terminal device 30.

[0017] The display unit 33 outputs information in a form recognizable by the user. The display unit 33 may be, for example, an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 33 may also be an interface for connecting an image display device to the terminal device 30. In this case, the display unit 33 generates a video signal for displaying image data and outputs the video signal to the image display device connected to itself. The display unit 33 may be a device that outputs sound such as a speaker. The display unit 33 may also be an interface for connecting a sound output device such as a speaker or headphones to the terminal device 30. In this case, the display unit 33 generates a sound signal for reproducing sound data and outputs the sound signal to the sound output device connected to itself. Note that the display unit 33 may be configured as a touch panel integrated with the input unit 32.

[0018] The storage unit 34 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 34 stores data used by the control unit 35. The storage unit 34 stores data required when the control unit 35 performs processing.

[0019] The control unit 35 is composed of a processor such as a CPU (Central Processing Unit) and memory (main memory). The control unit 35 functions as a memory control means 351, a selection means 352, a search means 353, a reading means 354, and a display control means 355 when the processor executes a program. Note that all or part of each function of the control unit 35 may be implemented using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded on a computer-readable recording medium. Computer-readable recording media include, for example, portable media such as flexible disks, magneto-optical disks, ROMs, CD-ROMs, and semiconductor memory devices (e.g., SSDs: Solid State Drives), as well as memory devices such as hard disks and semiconductor memory devices built into computer systems. The above program may be transmitted via a telecommunications line.

[0020] The control unit 35 may execute an application installed on its own device (terminal device 30). A program installed on the terminal device 30 may cause the computer to function as the terminal device 30 (storage control device) according to this embodiment. A specific example of such an application is an application provided to the terminal device 30 as a dedicated application for the plant monitoring system 1. Another specific example of such an application is a web browser application. Such an application may be pre-installed on the terminal device 30, or it may be downloaded each time a judgment process is executed. For example, if it is implemented as a web browser application, the terminal device 30 may download and execute the application from a device specified by the web server (for example, the web server itself or another server) when the terminal device 30 connects to a specific web server. The control unit 35 operates according to the program of the application being executed.

[0021] The control unit 35 controls the terminal device 30 in response to user operations and information received from the first equipment 11 of the first plant 10 or the second equipment 21 of the second plant 20. For example, the control unit 35 receives information transmitted from the first equipment 11 or the second equipment 21 via the network 70 at the communication unit 31, or receives information entered by the user via the input unit 32, generates screen data based on the received information, and displays the screen data on the display unit 33. Such screen data includes images and characters that represent the information transmitted from the first equipment 11 or the second equipment 21. For example, when the control unit 35 receives information transmitted from the first equipment 11 or the second equipment 21 via the network 70 at the communication unit 31, it generates audio data based on the received information and outputs the audio data from the display unit 33.

[0022] The memory control means 351 causes various types of information to be stored in the storage unit 34. In this embodiment, the memory control means 351 causes alarm information, alarm identification information, component information, guide information, and factor information to be stored in the storage unit 34.

[0023] Alarm information indicates a malfunction or abnormality in the plant's equipment. In this embodiment, the memory control means 351 stores multiple alarm information in the memory unit 34. In this embodiment, the multiple alarm information stored in the storage unit 34 includes first alarm information and second alarm information. The first alarm information is alarm information indicating a malfunction or abnormality in the first equipment 11 of the first plant 10. The second alarm information is alarm information indicating a malfunction or abnormality in the second equipment 21 of the second plant 20.

[0024] Alarm identification information is information that identifies alarm information. In this embodiment, the memory control means 351 stores multiple pieces of alarm identification information in the memory unit 34. In this embodiment, the plurality of alarm identification information stored in the storage unit 34 includes first alarm identification information and second alarm identification information. The first alarm identification information is alarm identification information that identifies the first alarm information. The second alarm identification information is alarm identification information that identifies the second alarm information. In this embodiment, alarm information and alarm identification information may be associated with each other and stored in the storage unit 34.

[0025] Component information is information that indicates the components that make up the equipment. In this embodiment, the memory control means 351 stores multiple pieces of component information in the memory unit 34. In this embodiment, the plurality of component information stored in the storage unit 34 includes first component information and second component information. The first component information is component information indicating the components that constitute the first equipment 11. The second component information is component information indicating the components that constitute the second equipment 21.

[0026] Factor information is information indicating the cause of the malfunction or abnormality indicated by the alarm information. In this embodiment, the memory control means 351 stores multiple pieces of factor information in the memory unit 34. In this embodiment, the plurality of factor information stored in the storage unit 34 includes first factor information and second factor information. The first factor information is factor information indicating the cause of the failure or abnormality indicated by the first alarm information. The second factor information is factor information indicating the cause of the failure or abnormality indicated by the second alarm information. In this embodiment, the memory control means 351 stores the first factor information and the first alarm identification information in association with each other in the memory unit 34, and also stores the second factor information and the second alarm identification information in association with each other in the memory unit 34.

[0027] Guide information is information that explains how to deal with the malfunction or abnormality indicated by the alarm information. In this embodiment, the memory control means 351 stores multiple pieces of guide information in the memory unit 34. In this embodiment, the plurality of guide information stored in the storage unit 34 includes first guide information and second guide information. The first guide information is guide information that explains how to deal with the malfunction or abnormality indicated by the first alarm information. The second guide information is guide information that explains how to deal with the malfunction or abnormality indicated by the second alarm information.

[0028] In this embodiment, the first guide information and the second guide information are stored in the storage unit 34 in association with the various types of information described above. Specifically, this is as follows. For example, the first guide information is stored in the storage unit 34 in association with the first alarm identification information. Similarly, the second guide information is stored in the storage unit 34 in association with the second alarm identification information. In this embodiment, "stored in association" may mean, for example, that the serial number of one record of the first guide information is stored in one field of the record of the first alarm identification information. Furthermore, the first guide information may be stored in the storage unit 34 in association with the first alarm identification information and the first component information. Also, the second guide information may be stored in the storage unit 34 in association with the second alarm identification information and the second component information. Furthermore, the first guide information may be stored in the storage unit 34 in association with the first alarm identification information and the first factor information. Also, the second guide information may be stored in the storage unit 34 in association with the second alarm identification information and the second factor information.

[0029] In this embodiment, the guide information, which explains how to deal with the malfunction or abnormality indicated by the alarm information, is updated by the user as appropriate. In other words, new guide information may be added by the user. In this case, the memory control means 351 may store new guide information corresponding to the first equipment 11 and the first alarm identification information in the memory unit 34 in association with each other. The memory control means 351 may also store new guide information corresponding to the second equipment 21 and the second alarm identification information in the memory unit 34 in association with each other. Furthermore, the memory control means 351 may store in the memory unit 34 new guide information corresponding to the first equipment 11, the first alarm identification information, and the first component information in association with each other. The memory control means 351 may also store in the memory unit 34 new guide information corresponding to the second equipment 21, the second alarm identification information, and the second component information in association with each other. Furthermore, the memory control means 351 may store in the memory unit 34 new guide information corresponding to the first equipment 11, the first alarm identification information, and the first factor information in association with each other. The memory control means 351 may also store in the memory unit 34 new guide information corresponding to the second equipment 21, the second alarm identification information, and the second factor information in association with each other.

[0030] The selection means 352 is a means for selecting a predetermined item from the various pieces of information stored in the memory unit 34. The selection means 352 selects, for example, predetermined alarm information and predetermined component information from among a plurality of alarm information and a plurality of component information stored in the memory unit 34. Furthermore, the selection means 352 may select a predetermined alarm identification information from among a plurality of alarm identification information stored in the storage unit 34. Furthermore, the selection means 352 may select predetermined alarm information and predetermined cause information from among the alarm information and cause information stored in the memory unit 34. The selection of this information by the selection means 352 is performed, for example, based on the user inputting appropriate instructions via the input unit 32. The user selects, for example, various pieces of information displayed on the display unit 33 by clicking or tapping. The information selected by the user may, for example, be highlighted on the display unit 33. Details of the information displayed on the display unit 33 will be described later.

[0031] The search means 353 is a means for searching the various types of information stored in the memory unit 34. The search means 353 searches for, for example, guide information associated with the alarm information and component information selected by the selection means 352, from among the guide information stored in the storage unit 34. Furthermore, the search means 353 may search for guide information associated with the alarm identification information selected by the selection means 352 from among the guide information stored in the storage unit 34. Furthermore, the search means 353 may search for guide information associated with the alarm information and factor information selected by the selection means 352 from among the guide information stored in the storage unit 34. The search means 353 retrieves this information, for example, when the selection means 352 selects information based on user input. Specifically, for example, when the selection means 352 selects information based on user input, the selected information is used as a key to search the guide information stored in the storage unit 34. The retrieved information may be highlighted on the display unit 33, for example, or displayed on a newly opened window screen.

[0032] The reading means 354 is a means for reading guide information stored in the storage unit 34. The reading of guide information by the reading means 354 is performed, for example, when the search means 353 searches for the various types of information described above. The guide information read by the reading means 354 may be displayed, for example, in individual windows on the display unit 33. In this case, the search means 353 may retrieve multiple guide information at once. In such cases, the reading means 354 may read one guide information in one of the following ways. In other words, the reading means 354 may, for example, read out the guide information that is newer than the others when there are multiple guide information items retrieved by the search means 353. Newer than others may mean, for example, that the date and time registered by the user is later than the others. The registration date and time may be stored in the storage unit 34 as appropriate, in association with the guide information. Furthermore, if there are multiple pieces of guide information retrieved by the search means 353, the reading means 354 may read the guide information retrieved by the search means 353 that has a higher number of references than the others. The number of references may be, for example, the number of times the guide information has been read by the reading means 354. The number of references may be stored in the storage unit 34 each time the guide information is read by the reading means, associated with the guide information. Furthermore, if there are multiple guide information items retrieved by the search means 353, the reading means 354 may read the guide information item with a higher recommendation rating than the others. The recommendation rating may be determined, for example, by the user appropriately selecting from elements such as the update date and time of the guide information, the number of times it has been viewed, the monitor who created it, etc., or the language model may determine the recommendation rating, or it may be determined by any other arbitrary method. The recommendation rating may be associated with the guide information and appropriately stored in the storage unit 34. Furthermore, if there are multiple pieces of guide information retrieved by the search means 353, the reading means 354 may read the guide information retrieved by the search means 353 that was created by a designated supervisor. The designated supervisor may be, for example, a highly skilled supervisor. Information on supervisors, including the designated supervisor, may be stored in the storage unit 34 in association with the guide information as appropriate. In this case, the designated supervisor and other supervisors may be stored separately.

[0033] The display control means 355 causes the display unit 33 to display various information. Specifically, the display control means 355 converts the various information processed by the means described above and stored in the storage unit 34 into information that can be visually viewed by the user and displays it on the display unit 33. This allows the user to operate the terminal device 30 while visually viewing the display unit 33.

[0034] Figure 3 shows a first example of information displayed on the display unit 33 by the display control means 355. As shown in Figure 3, the display control means 355 causes, for example, the alarm list table AL to be displayed on the display unit 33. In the example shown in Figure 3, the alarm list table AL is displayed near the center of the display unit 33, but it may be displayed in any other location as appropriate.

[0035] Alarm List AL is a list of various information regarding alarms issued in Equipment 11 of Plant 10 and Equipment 21 of Plant 20. Alarm List AL displays information about alarms issued in Equipment 11 and Equipment 21, row by row. The information displayed for each alarm in Alarm List AL includes, for example, level information, occurrence information, recovery information, alarm identification information, alarm information, plant information, and equipment information. In this embodiment, the various pieces of information displayed in each row of the alarm list table AL are associated with each other as history information and stored in the storage unit 34. The display control means 355 may refer to the history information thus registered and display it in the alarm list table AL. Specifically, this is as follows. Specifically, for example, when an alarm is issued, the time of the alarm is registered in association with the alarm identification information and alarm information stored in the storage unit 34 as described above, the severity level of the issued alarm, information about the affiliation of the equipment that issued the alarm (plant information), and information about the equipment that issued the alarm (equipment information). This generates historical information that can be referenced by the display control means 355. Then, when the system recovers from the event related to the alarm, the time of recovery is registered in association with the historical information generated as described above. Preferably, the historical information registered in this way is registered each time an alarm is issued and stored as data. This allows, for example, a user to refer to it as information about alarms that have been issued in the past.

[0036] In this embodiment, unless otherwise specified, the first facility 11 and the second facility 21 will be described as gas turbine on-site. The first facility 11 will consist of a gas turbine power generation facility, three boiler facilities, a drainage facility, a cooling tower facility, an instrumentation air facility, and a deoxygenation facility. The second facility 21 will consist of all the facilities of the first facility 11 except for the cooling tower facility.

[0037] In this embodiment, the alarm list table AL includes, for example, a level information image AL1, an occurrence information image AL2, a recovery information image AL3, an alarm identification information image AL4, an alarm information image AL5, a plant information image AL6, and an equipment information image AL7, as shown in Figure 3. In the example shown in Figure 3, the top row of the alarm list table AL displays an image showing the content of the information for each column in the alarm list table AL. Specifically, it is as follows:

[0038] The level information image AL1 is an image that displays level information indicating the severity of alarms issued by the first equipment 11 and the second equipment 21. The level information may be stored in the storage unit 34 in advance, for example, in association with the content of the alarm. As shown in Figure 3, the level information image AL1 is displayed in the column labeled "Level" in the top row of the alarm list table AL. In the example shown in Figure 3, the level information displayed by the level information image AL1 consists of two categories: "severe" and "mild." By displaying the level information for each alarm in the alarm list table AL, users can better understand the severity of the alarms that have been triggered.

[0039] The event information image AL2 is an image that shows the date and time when the event related to the alarm occurred. As shown in Figure 3, the event information image AL2 is displayed in the column labeled "Occurrence" in the top row of the alarm list table AL. In the example shown in Figure 3, the incident information image AL2 displays the date, time, and time (hour, minute, second) of the event related to the alarm. By showing the date and time of the event in the alarm list table AL, users can understand when the event occurred.

[0040] The recovery information image AL3 is an image that shows the date and time when the system recovered from the event related to the alarm. As shown in Figure 3, the recovery information image AL3 is displayed in the column labeled "Recovered" in the top row of the alarm list table AL. In the example shown in Figure 3, the recovery information image AL3 displays the date, time, and seconds of recovery from the alarm-related event. Also in the example shown in Figure 3, the second row from the top of the alarm list table AL is blank, and the dates and times are displayed in the rows from the third row onward. In this case, the blank recovery information image AL3 indicates that recovery from the alarm-related event has not occurred. Thus, by showing the date and time of recovery from the alarm-related event in the alarm list table AL, and leaving it blank if recovery has not occurred, it helps the user to understand whether or not recovery from the alarm-related event has been completed, and if so, when the recovery occurred.

[0041] Alarm identification information image AL4 is an image that shows the alarm identification information related to the issued alarm. As shown in Figure 3, alarm identification information image AL4 is displayed in the column labeled "Alarm Tag" in the top row of the alarm list table AL. In the example shown in Figure 3, the alarm identification information shown by the alarm identification information image AL4 consists of multiple codes separated by hyphens (-). For example, in the example shown in Figure 3, the alarm identification information image AL4 displayed in the second row from the top of the alarm list table AL shows "AL-UN-GT-001".

[0042] In this case, for example, "AL" means alarm, and the alarm identification information image AL4 indicates alarm identification information. "AL" is included in all of the alarm identification information images AL4 shown in Figure 3.

[0043] "UN" indicates that the alarm identification information shown by the corresponding alarm identification information image AL4 is unique to the equipment related to the alarm. If alarm identification information image AL4 contains "UN", it indicates that the corresponding alarm identification information cannot be shared with other equipment. In the example shown in Figure 3, some alarm identification information images AL4, starting from the fifth row from the top of the alarm list table AL, have the code "CM" instead of "UN". This "CM" indicates that the alarm identification information shown by the corresponding alarm identification information image AL4 can be shared with other equipment. If alarm identification information image AL4 contains "CM", it indicates that the corresponding alarm identification information can be shared with other equipment.

[0044] "GT" stands for gas turbine, indicating that the alarm identification information shown by alarm identification information image AL4 pertains to a gas turbine. In the example shown in Figure 3, the alarm identification information image AL4 from the third row onwards in the alarm list table AL may have the symbols "Boir1", "Boir2", "Boir3", "Drain", "Cool", "InstAir", and "Do" instead of "GT". In this case, "Boir1", "Boir2", and "Boir3" refer to the first boiler, the second boiler, and the third boiler, respectively. "Drain" refers to the drainage equipment. "Cool" refers to the cooling tower equipment. "InstAir" refers to the instrumentation air equipment. "Do" refers to the deoxygenation equipment. Thus, in this embodiment, the alarm identification information may also indicate components that constitute the equipment. That is, the first alarm identification information may indicate components that constitute the first equipment 11, and the second alarm identification information may indicate components that constitute the second equipment 21. In this case, each of the above-mentioned symbols in the alarm identification information may be component information indicating components that constitute the equipment. Furthermore, in this embodiment, the first alarm identification information and the second alarm identification information may be common in at least part. If the alarm identification information for the first equipment 11 and the alarm identification information for the second equipment 21 are common, the user can, for example, recognize a failure or abnormality in the second equipment 21 in the same way as a failure or abnormality in the first equipment 11.

[0045] In this embodiment, the first equipment 11 and the second equipment 21 differ in that the second equipment 21 does not have a cooling tower. In this case, the first alarm identification information and the second alarm identification information may be common, except for the alarm identification information AL4 shown in the third row from the bottom of the alarm list table AL in Figure 3, which includes the code "Cool" meaning the cooling tower. As shown in the alarm list table AL in Figure 3, the alarm identification information image AL4 related to such alarm identification information has the code "CM" to indicate that the alarm identification information can be shared. On the other hand, the alarm identification information shown in the alarm identification information image AL4 shown in the third row from the bottom of the alarm list table AL in Figure 3 has the code "UN" to indicate that the alarm identification information cannot be shared. As described above, the second facility 21 does not have the cooling tower equipment that the first facility 11 has. At this time, in the third row from the bottom of the alarm list table AL shown in Figure 3, the alarm identification information image AL4 is shown as "AL-UN-Cool-001". According to this alarm identification information image AL4, the code "UN" indicates that the alarm identification information related to the cooling tower equipment, indicated by the code "Cool", cannot be shared with the second facility 21 of the second plant 20.

[0046] Furthermore, even if different equipment is provided between multiple pieces of equipment, alarm identification information for common parts may be shared. That is, for example, even if the first piece of equipment 11 of the first plant 10 is equipped with a stoker furnace and the second piece of equipment 21 of the second plant 20 is equipped with a melting furnace, if parts such as drainage equipment, cooling tower equipment, instrumentation air equipment, and deoxygenation equipment are common, common alarm identification information may be used for those parts.

[0047] "001" is a number assigned individually to each of the alarm identification information shown in the alarm identification information image AL4. For example, if the alarm identification information image AL4 shows "AL-UN-GT-001", it indicates that the corresponding alarm identification information is the first of the alarm identification information shown by "AL", "UN", and "GT" as described above. The alarm indicated by "001" may be something other than a numerically represented condition, such as temperature or pressure. For example, the alarm indicated by "001" may be used for situations such as equipment not starting properly or poor communication between equipment.

[0048] In the example shown in Figure 3, some alarm identification information images AL4, starting from the third row from the top of the alarm list table AL, have the symbols "H", "L", "PH", "PHH", "PL", and "PLL" instead of "001". The symbols "H" and "L" in these codes indicate that the value is "high" or "low" relative to the standard value set in the equipment, respectively. Alarms indicated by such codes may relate to numerically expressed conditions, such as temperature or pressure.

[0049] Furthermore, the "P" in these symbols indicates a state just before an alarm is triggered. In this embodiment, the information triggered in the state just before an alarm is triggered is called a notification alarm. The notification alarm helps prevent the alarm from being triggered by informing the user that the equipment related to the alarm identification information shown by the alarm identification information image AL4 is in a state just before an alarm is triggered. The threshold for triggering the notification alarm may be arbitrarily set by the user. Also, the threshold does not need to be common among multiple plants. In notification alerts, if two symbols such as "H" or "L" are present, it indicates a higher degree of deviation from the baseline value than if only one of these symbols is present. For example, "PH" indicates that the temperature, pressure, etc., in the equipment has begun to rise above the set reference value, and "PHH" indicates that the temperature, pressure, etc., in the equipment has risen even higher than the state indicated by "PH". In this case, if the temperature, pressure, etc., in the equipment rises higher than the state indicated by "PHH", an alarm will be triggered. In this case, the alarm identification information image AL4 may display the code "H" with the "P" removed. Furthermore, for example, "PL" indicates that the temperature, pressure, etc., in the equipment has begun to fall below the set reference value, and "PLL" indicates that the temperature, pressure, etc., in the equipment has fallen even lower than the state indicated by "PL". In this case, if the temperature, pressure, etc., in the equipment falls below the state indicated by "PLL", an alarm will be triggered. In this case, the alarm identification information image AL4 may display the code "L" with the "P" removed.

[0050] In this way, by displaying information that identifies the alarm in the alarm list table AL, it helps users to easily understand the specific details of the alarms and notification alerts that have been issued.

[0051] Alarm information image AL5 is an image that shows alarm information related to an issued alarm. As shown in Figure 3, alarm information image AL5 is displayed in the column labeled "Alarm Name" in the top row of the alarm list table AL. In the example shown in Figure 3, the alarm information displayed by the alarm information image AL5 is written in natural language. For example, in the example shown in Figure 3, from top to bottom, it displays: "Startup congestion", "Discharge gas pressure value PHH", "Discharge gas pressure value PL", "Intake gas pressure value PH", "Bypass control valve opening output value H", "Communication failure", "Compressor vibration value PLL", and "Compressor capacity limit value L". For example, "startup congestion" indicates that the equipment in question is not starting up properly. Similarly, "communication failure" indicates that the equipment in question is unable to communicate properly. Each of the other alarm information indicates a notification warning, showing that the pressure value, valve opening output value, vibration value, and capacity limit value of the respective equipment are in a state indicated by the symbols "PHH," "PL," "PH," "H," "PLL," and "L," respectively.

[0052] Plant information image AL6 is an image that shows plant information indicating the affiliation of the equipment that triggered the alarm. As shown in Figure 3, plant information image AL6 is displayed in the column labeled "Plant" in the top row of the alarm list table AL. In the example shown in Figure 3, the plant information displayed by the plant information image AL6 consists of two parts: "Plant 1" and "Plant 2". In this way, the alarm list table AL indicates the affiliation of the equipment that triggered the alarm, which helps users understand the affiliation of the equipment that triggered the alarm.

[0053] Equipment information image AL7 is an image that shows equipment information indicating the equipment for which an alarm has been triggered. As shown in Figure 3, equipment information image AL7 is displayed in the column labeled "Equipment" in the top row of the alarm list table AL. In the example shown in Figure 3, the equipment information shown by equipment information image AL7 consists of two pieces of equipment: "Equipment 1" and "Equipment 2". In the example shown in Figure 3, the equipment information displayed by the equipment information image AL7 consists of two items: "Equipment 1" and "Equipment 2". In this case, among the alarm information and alarm identification information, the items displayed as "Equipment 1" are the first alarm information and the first alarm identification information, respectively. Similarly, among the alarm information and alarm identification information, the items displayed as "Equipment 2" are the second alarm information and the second alarm identification information, respectively. In this way, by showing the equipment on which an alarm has been triggered in the alarm list table AL, it helps users to understand which equipment has triggered an alarm. Furthermore, as described above, in this embodiment, there are multiple first equipment 11s in the first plant 10, and multiple second equipment 21s in the second plant 20. In this embodiment, the first alarm information and the second alarm information may each indicate a failure or abnormality of one of the multiple pieces of equipment. That is, for example, the first alarm information may indicate a failure or abnormality of each of the aforementioned pieces of equipment in the first equipment 11, and the second alarm information may indicate a failure or abnormality of each of the aforementioned pieces of equipment in the second equipment 21.

[0054] In the example shown in Figure 3, the third row from the top of the alarm list table AL is highlighted in a different color from the other rows. Such a display indicates, for example, that the user has selected information regarding the relevant alarm. The user may select the information by, for example, by entering appropriate instructions via the input unit 32.

[0055] Furthermore, in the example shown in Figure 3, the display control means 355 may display an emergency stop button F1, a print button F2, a buzzer stop button F3, and a current time display unit F4, in addition to the alarm list table AL containing the various information described above. The emergency stop button F1 is, for example, a button for emergency stopping of equipment. The print button F2 is, for example, a button for printing the alarm list AL displayed on the display unit 33. The buzzer stop button F3 is, for example, a button for stopping the buzzer in equipment, etc. These buttons may be operated, for example, by the user selecting them via the input unit 32 by clicking or tapping. The current time display unit F4 is, for example, the part that displays the current time at the location where the terminal device 30 is installed. For example, if there is a time difference between the location where the terminal device 30 is installed and the location where the equipment is installed, the time displayed on the current time display unit F4 may be changed as appropriate. Furthermore, as shown in Figure 3, alarms displayed in the alarm list table AL that have not been restored, or those selected by the user, may be displayed at the top of the display unit 33 as appropriate.

[0056] Figure 4 shows a second example of information displayed on the display unit 33 by the display control means 355. As shown in Figure 4, the display control means 355 may cause the operator guide window OW to be displayed on the display unit 33. The operator guide window OW may be displayed, for example, when one of the alarm-related items in the alarm list table AL displayed on the display unit 33 is selected. The operator guide window OW may be displayed, for example, superimposed on the alarm list table AL on the display unit 33.

[0057] The Operator Guide Window (OW) is a window that individually displays guide information corresponding to the malfunction or abnormality related to the alarm displayed in the Alarm List (AL). In the Operator Guide Window (OW), guide information corresponding to the alarm selected by the user from among the alarms displayed in the Alarm List (AL) is displayed. In this embodiment, the operator guide window OW includes, for example, an alarm number image OW1, an alarm image OW2, a guide number image OW3, a guide information image OW4, a new registration button OW5, an edit button OW6, and a close button OW7, as shown in Figure 4.

[0058] Alarm number image OW1 is an image that displays the sequential number of the alarm information stored in the memory unit 34. The sequential number of the alarm information may be assigned, for example, according to the order in which it is stored in the memory unit 34, regardless of its type or content.

[0059] Alarm image OW2 is an image that shows the alarm information selected by the user from the alarm information displayed in the alarm list table AL. The content of alarm image OW2 corresponds to the content of alarm information image AL5 in the alarm list table AL. In the example shown in Figure 4, alarm image OW2 shows "Discharge gas pressure value PHH". In other words, in the example shown in Figure 4, alarm information image AL5 related to "Discharge gas pressure value PHH" has been selected from the alarm information displayed in the alarm list table AL.

[0060] Guide number image OW3 is an image that shows the sequential number of the guide information registered in response to the alarm information, and the update time of the corresponding guide information. The aforementioned sequential number of the guide information may be assigned, for example, in the order in which it was registered. In the example shown in Figure 4, the guide number image OW3 displays "12: 2023 / 09 / 08 10:12:34". In other words, in the example shown in Figure 4, the 12th guide information, registered in response to the alarm information, was registered at the aforementioned date and time.

[0061] Guide information image OW4 is an image that displays guide information. The content of guide information image OW4 is registered in correspondence with alarm information. Alarm information registered in this manner may be stored in the storage unit 34. Furthermore, alarm information stored in the storage unit 34 may be read out by the reading means 354 and displayed as guide information image OW4. In the example shown in Figure 4, the guide information image OW4 displays "Observation." Such information may be registered by the user as appropriate.

[0062] In this embodiment, the first equipment 11 and the second equipment 21 are common to each other except that the second equipment 21 does not have a cooling tower. In this case, the methods for dealing with malfunctions or abnormalities indicated by alarm information in the first equipment 11 and the second equipment 21 may be the same.

[0063] Furthermore, if the first equipment 11 and the second equipment 21 are different pieces of equipment, even if the alarm information is the same, different guide information may be registered for each. The following explanation will take the example of a case where the first equipment 11 and the second equipment 21 are equipped with a common boiler, and the second equipment 21 is not equipped with the auxiliary burner that the first equipment 11 is equipped with. In such a case, for example, the pressure-related parts of the common boiler may differ as follows. That is, for example, suppose a boiler pressure anomaly occurs in the first equipment 11 and the second equipment 21 as described above. In this case, in the first equipment 11, which is equipped with an auxiliary burner, information may be registered as guide information to check whether the auxiliary burner was extinguished before the pressure anomaly occurred. On the other hand, in the second equipment 21, which is not equipped with an auxiliary burner, information may be registered as guide information to check whether the depressurization valve that depressurizes the drum is performing its depressurization operation at the appropriate pressure. As described above, components in equipment can be the cause of the malfunction or abnormality indicated by the alarm information. In such cases, information about the component related to the abnormality or malfunction related to the alarm, in other words, information about the component mentioned in the guide information, may be considered the cause information. In the example above, for example, the auxiliary burner or the depressurization valve may be considered the cause, and the component information indicating these components may be considered the cause information. Furthermore, in such cases, the component information, which is information about a component and is included in the alarm identification information described above, may also be called cause information. In this embodiment, it can be said that cause information is stored in the storage unit 34 in association with the alarm identification information. In such cases, for example, a user can grasp the cause information by checking the alarm identification information.

[0064] The New Registration button OW5 is a button to select when registering new guide information. For example, a user may register guide information by selecting the New Registration button OW5 via the input section 32 by clicking or tapping it, and then entering the appropriate information. The edit button OW6 is the button to select when editing registered guide information. For example, a user may edit registered guide information by selecting the edit button OW6 via the input section 32 by clicking or tapping it, and then entering the appropriate information. The close button OW7 is the button selected when closing the operation guide window OW. The user may close the operation guide window OW and return to the alarm list table AL by selecting the close button OW7 via the input unit 32, for example.

[0065] (Regarding the control method) Next, the control method by the terminal device 30 according to this embodiment will be explained with reference to Figure 5. Figure 5 shows a flowchart of the memory control method according to the embodiment. The control method using the terminal device 30 refers to a method for the user to use the terminal device 30 to check various information, register guide information, and so on. The control method by the terminal device 30 includes, for example, a storage control step S1, a selection step S2, a search step S3, a reading step S4, and a display control step S5, as shown in Figure 5.

[0066] The memory control step S1 is a step in which the memory control means 351 causes various types of information to be stored in the storage unit 34. Specifically, in the memory control step S1, for example, the memory control means 351 causes multiple alarm information indicating a failure or abnormality of the plant equipment to be stored in the storage unit 34, and also causes multiple alarm identification information to be stored in the storage unit 34 to identify the alarm information. In addition, in the memory control step S1, the memory control means 351 may also cause, for example, component information, guide information, and factor information to be stored in the storage unit 34. Details of the memory control means 351's control of these types of information are as described above and will therefore not be explained further. In this embodiment, the method of memory control step S1 by the memory control means 351 may also be called a memory control method.

[0067] Selection step S2 is a step in which the selection means 352 selects a predetermined piece of information from the various pieces of information stored in the storage unit 34. As described above, the selection of information by the selection means 352 is performed, for example, based on the user inputting appropriate instructions via the input unit 32. In this embodiment, selection step S2 may be performed by the user operating the terminal device 30.

[0068] Search step S3 is a step in which the search means 353 searches for the various types of information stored in the storage unit 34. As described above, the search by the search means 353 is performed when the selection means 352 selects information based on instructions from the user. In this embodiment, search step S3 may be performed when the user operates the terminal device 30 and selection step S2 is performed.

[0069] The reading step S4 is a step in which the reading means 354 reads the guide information stored in the storage unit 34. As described above, the reading of the guide information by the reading means 354 is performed, for example, when the search means 353 searches for the various types of information described above. In this embodiment, the search step S3 may be performed as a result of the search step S3 being performed as described above.

[0070] The display control step S5 is a step in which the display control means 355 causes the display unit 33 to display various information. Specifically, the display control step S5 is a step in which the display control means 355 causes the display unit 33 to display various information, which has been processed by the means described above and stored in the storage unit 34, in a way that is visible to the user. The display control step S5 may be performed at any time, for example, while the above steps are being performed. The control method according to this embodiment is performed as described above.

[0071] Figure 6 is a schematic diagram showing an example of the hardware configuration of the information processing device 90 applied to the embodiment. The information processing device 90 comprises a processor 91, main memory 92, communication interface 93, auxiliary storage device 94, input / output interface 95, and internal bus 96. The processor 91, main memory 92, communication interface 93, auxiliary storage device 94, and input / output interface 95 are connected to each other via the internal bus 96 so as to be able to communicate with each other. The information processing device 90 may be applied to, for example, a terminal device 30. In this case, for example, the communication unit 31 may be configured using the communication interface 93. For example, the storage unit 34 may be configured using the auxiliary storage device 94. Furthermore, the control unit 35 may be configured using the processor 91 and the main memory 92.

[0072] As described above, the terminal device 30 (storage control device) according to this embodiment includes a storage control means 351 that stores multiple alarm information indicating a failure or abnormality of plant equipment in the storage unit 34, and also stores multiple alarm identification information for identifying the alarm information in the storage unit 34. This makes it possible to store information related to alarms issued in the plant. Furthermore, of the multiple alarm identification information stored in the memory unit 34, at least a portion of the first alarm identification information that identifies the first alarm information indicating a failure or abnormality of the first equipment 11 of the first plant 10 and the second alarm identification information that identifies the second alarm information indicating a failure or abnormality of the second equipment 21 of the second plant 20 are common. As a result, for example, a user (e.g., a user, artificial intelligence, or program) can grasp the alarm identification information related to the failure or abnormality of either the first equipment 11 or the second equipment 21, and then grasp the failure or abnormality of the other equipment by associating it with the alarm identification information. Therefore, for example, it becomes easier for users to more efficiently grasp the failures or abnormalities of multiple pieces of equipment.

[0073] Furthermore, the multiple component information stored in the memory unit 34 includes first component information indicating the components constituting the first equipment 11, and second component information indicating the components constituting the second equipment 21. The components constituting the first equipment 11 and the components constituting the second equipment 21 differ in at least some respects. As a result, for example, a user can understand that the components constituting the first equipment 11 and the components constituting the second equipment 21 differ in at least some respects by understanding the component information. Therefore, for example, even if a common failure or abnormality occurs in the first equipment 11 and the second equipment 21, it becomes easier for a user to understand that the response to the failure or abnormality may differ.

[0074] Furthermore, first guide information explaining how to deal with the malfunction or abnormality indicated by the first alarm information is stored in the storage unit 34 in association with the first alarm identification information and the first component information. Similarly, second guide information explaining how to deal with the malfunction or abnormality indicated by the second alarm information is stored in the storage unit 34 in association with the second alarm identification information and the second component information. This makes it easier for users, for example, to distinguish from among multiple pieces of guide information that all relate to the same component that is the target of the equipment malfunction or abnormality.

[0075] Furthermore, the system includes a selection means 352 for selecting predetermined alarm information and predetermined component information from among a plurality of alarm information and a plurality of component information stored in the storage unit 34, and a search means 353 for searching for guide information associated with the alarm information and component information selected by the selection means 352 from among the guide information stored in the storage unit 34. This makes it possible, for example, for users to reliably and easily find the guide information associated with the alarm information and component information selected by the selection means 352. Also, for example, it makes it possible for users to more reliably and easily find among a plurality of guide pieces of information that are related to the same component that is the target of action for equipment failure or abnormality.

[0076] Furthermore, the memory control means 351 stores new guide information corresponding to the first equipment 11, the first alarm identification information, and the first component information in the memory unit 34 in association with each other. This allows, for example, newly added guide information for the equipment to be stored in the memory unit 34 in association with appropriate alarm identification information and component information. Therefore, for example, it becomes easier for the user to deal with equipment failures or abnormalities more effectively.

[0077] Furthermore, the first alarm identification information also indicates the components constituting the first equipment 11, and the second alarm identification information also indicates the components constituting the second equipment 21. The components constituting the first equipment 11 and the components constituting the second equipment 21 are at least partially different. This allows users, for example, to understand that the components constituting the first equipment 11 and the components constituting the second equipment 21 are at least partially different, even through the alarm identification information. Therefore, it becomes easier for users, for example, to understand that the components constituting the first equipment 11 and the components constituting the second equipment 21 are different. Therefore, it becomes easier for users, for example, to understand that even if a common failure or abnormality occurs in the first equipment 11 and the second equipment 21, the response to the failure or abnormality may differ.

[0078] Furthermore, first guide information explaining how to deal with the malfunction or abnormality indicated by the first alarm information is stored in the storage unit 34 in association with the first alarm identification information. Similarly, second guide information explaining how to deal with the malfunction or abnormality indicated by the second alarm information is stored in the storage unit 34 in association with the second alarm identification information. These alarm identification pieces also indicate the components that make up the equipment. This allows, for example, a user to understand the alarm identification information and identify the component that needs to be addressed in response to the malfunction or abnormality of the equipment. It also makes it easier for a user to distinguish between multiple pieces of guide information that refer to the same component that needs to be addressed in response to the malfunction or abnormality of the equipment.

[0079] Furthermore, the system includes a selection means 352 for selecting a predetermined alarm identification information from among multiple alarm identification information stored in the storage unit 34, and a search means 353 for searching for guide information associated with the alarm identification information selected by the selection means 352 from among the guide information stored in the storage unit 34. This makes it possible for users, for example, to reliably and easily find the guide information associated with the alarm identification information selected by the selection means 352. Also, it makes it possible for users, for example, to more reliably and easily find among multiple pieces of guide information that refer to the same part that is the target of action for equipment failure or abnormality.

[0080] Furthermore, the memory control means 351 stores new guide information corresponding to the first equipment 11 in the memory unit 34 in association with the first alarm identification information. This allows, for example, newly added guide information to the equipment to be stored in the memory unit 34 in association with appropriate alarm identification information. Therefore, for example, it becomes easier for the user to deal with equipment failures or abnormalities more effectively.

[0081] Furthermore, the memory control means 351 stores in the memory unit 34 the first factor information indicating the cause of the failure or abnormality indicated by the first alarm information in association with the first alarm identification information, and also stores in the memory unit 34 the second factor information indicating the cause of the failure or abnormality indicated by the second alarm information in association with the second alarm identification information. Therefore, for example, a user can easily distinguish between multiple alarm pieces of information that have the same corresponding cause of failure or abnormality.

[0082] Furthermore, the first guide information, which explains how to deal with the malfunction or abnormality indicated by the first alarm information, is stored in the storage unit 34 in association with the first alarm identification information and the first cause information. Similarly, the second guide information, which explains how to deal with the malfunction or abnormality indicated by the second alarm information, is stored in the storage unit 34 in association with the second alarm identification information and the second cause information. This makes it easier for a user, for example, to distinguish between multiple pieces of guide information that correspond to the same alarm information and the same cause of malfunction or abnormality.

[0083] Furthermore, the system includes a selection means 352 for selecting predetermined alarm information and predetermined cause information from among the alarm information and cause information stored in the memory unit 34, and a search means 353 for searching for guide information associated with the alarm information and cause information selected by the selection means 352 from among the guide information stored in the memory unit 34. This makes it possible, for example, for a user to reliably and easily find the guide information associated with the alarm information and cause information selected by the selection means 352. Also, for example, it makes it possible for a user to more reliably and easily find guide information that corresponds to the same cause of failure or abnormality from among multiple pieces of guide information.

[0084] Furthermore, the memory control means 351 stores new guide information corresponding to the first equipment 11, first alarm identification information, and first cause information in the memory unit 34 in association with each other. This allows, for example, newly added guide information to the equipment to be stored in the memory unit 34 in association with appropriate alarm identification information and cause information. Therefore, for example, it becomes easier for the user to understand the cause of equipment failure or abnormality. Also, for example, it becomes easier for the user to deal with equipment failure or abnormality more effectively.

[0085] Furthermore, if there are multiple guide information items retrieved by the search means 353, the system is further equipped with a reading means 354 that retrieves the guide information item that is newer than the others. This makes it easier for the user to refer to newer guide information, for example. Therefore, it makes it easier for the user to deal with equipment failures or abnormalities more efficiently.

[0086] Furthermore, if there are multiple pieces of guide information retrieved by the search means 353, the system is further equipped with a reading means 354 that retrieves the guide information retrieved by the search means 353 that is referenced more frequently than others. This makes it easier for users, for example, to refer to guide information corresponding to methods for dealing with equipment failures or abnormalities that are performed more frequently. Therefore, it makes it easier for users to deal with equipment failures or abnormalities more efficiently.

[0087] Furthermore, if there are multiple guide information items retrieved by the search means 353, the system is further equipped with a reading means 354 that retrieves the guide information item with a higher recommendation level than the others. This makes it easier for the user to refer to guide information with a higher recommendation level. Therefore, it makes it easier for the user to deal with equipment failures or abnormalities more efficiently.

[0088] Furthermore, if there are multiple pieces of guide information retrieved by the search means 353, the system is further equipped with a reading means 354 that retrieves the guide information created by a designated monitor from among the guide information retrieved by the search means 353. This allows, for example, if the designated monitor has a high level of skill, the user to more easily refer to more reliable guide information. Therefore, for example, the user can more easily deal with equipment failures or abnormalities more efficiently.

[0089] Furthermore, since there are multiple pieces of equipment, the first and second alarm information each indicate a failure or abnormality in multiple pieces of equipment. This makes it easier for users, for example, to simultaneously understand abnormalities or failures in multiple pieces of equipment.

[0090] (Second Embodiment) Next, a plant monitoring system according to a second embodiment of the present invention will be described with reference to Figure 7. In this second embodiment, the same reference numerals are used for parts that are the same as those in the first embodiment, and their descriptions are omitted. Only the differences will be described. Figure 7 is a schematic block diagram showing the system configuration of the plant monitoring system according to the second embodiment. The second plant monitoring system 2 (plant monitoring system) shown in Figure 7 differs from the first embodiment in that the terminal device 30 (memory control device) in the first embodiment is provided at the first site A1, the second site A2, and the remote location A3, respectively. In other words, in the second embodiment, the second plant monitoring system 2 comprises a first plant 10, a second plant 20, a first terminal device 30A, a second terminal device 30B, and a third terminal device 30C, as shown in Figure 7.

[0091] The first terminal device 30A is a terminal device 30 located within the first site A1 of the first plant 10. The first terminal device 30A stores, for example, first alarm information in the storage unit 34. The second terminal device 30B is a terminal device 30 located within the second site A2 of the second plant 20. The second terminal device 30B stores, for example, second alarm information in the storage unit 34. The third terminal device 30C is a terminal device 30 located at a remote location A3, separated from the first site A1 and the second site A2. The third terminal device 30C stores, for example, first alarm information and second alarm information in a storage unit 34. In addition, the first terminal device 30A may store the second alarm information in the storage unit 34, and the second terminal device 30B may store the first alarm information in the storage unit 34.

[0092] The first terminal device 30A, the second terminal device 30B, and the third terminal device 30C may each be connected to one another by a network 70, for example. This may enable them to communicate information with each other. Furthermore, the information displayed on the display unit 33 may be common to each of the first terminal device 30A, the second terminal device 30B, and the third terminal device 30C. That is, the various types of information described in the first embodiment may be displayed on each of the first terminal device 30A, the second terminal device 30B, and the third terminal device 30C.

[0093] Figure 8 shows an example of information displayed on the display unit 33 of the first terminal device 30A or the second terminal device 30B in the second embodiment.
