[0006] Plant inspections and the like are performed by plant operators and on-site workers. Operators are employees who manage the operation of the plant. On-site workers are employees who perform practical work related to the plant equipment. For example, operators give instructions regarding the inspection of the plant equipment, and the on-site workers inspect the plant equipment in accordance with the instructions.

[0007] For example, suppose a system that displays a model of plant equipment is used by plant employees, including operators and field workers. The system displays the model on a terminal used by the operator and a terminal used by the field worker when inspecting a specific piece of equipment in the plant. Here, plant employees are examples of users of the system that displays the model of plant equipment. As described above, the roles of operators and field workers during inspections are different. Therefore, it is necessary to control the display of the system according to multiple users.

[0008] The present disclosure has been made in consideration of the above-mentioned problems, and one of its objects is to provide a plant management device and the like that can support work in inspecting a plant.

[0009] A plant management device according to one aspect of the present disclosure includes a display control means for displaying a plant model, which is an image of equipment included in a plant, on a display device, and a reception means for receiving operations by a user on the plant model displayed on the display device, and the display control means displays information corresponding to the user's role and the operation on the display device operated by the user.

[0010] A plant management method according to one aspect of the present disclosure displays a plant model, which is an image of equipment included in a plant, on a display device, accepts operations by a user on the plant model displayed on the display device, and displays information corresponding to the user's role and the operation on the display device operated by the user.

[0011] A computer-readable storage medium according to one aspect of the present disclosure stores a program that causes a computer to execute a process of displaying a plant model, which is an image of equipment included in a plant, on a display device and a process of accepting user operations on the plant model displayed on the display device, and that, in the display process, causes information corresponding to the user's role and the operation to be displayed on the display device operated by the user.

[0012] According to the present disclosure, it is possible to support work during plant inspections.

[0014] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0015] First Embodiment First, a description will be given of a plant inspection. In the present disclosure, a plant inspection is performed by at least a plant operator and a field worker. The plant operator is an employee who operates the plant. For example, the operator operates the plant by operating a control panel or the like in the plant's central control room. The field worker is an employee who performs practical work on equipment included in the plant. The equipment included in the plant is structures such as machines, piping, wiring, and tanks used for production.

[0016] In one example of a plant inspection, an operator gives instructions to a field worker. For example, if an abnormality occurs in equipment, the operator gives the field worker instructions regarding the inspection of the equipment. The field worker who receives the instructions inspects the equipment in accordance with the instructions. The plant management device of the present disclosure is used in such a plant inspection, as an example.

[0017] Next, an overview of the plant management device of the present disclosure will be described.

[0018] 1 is a block diagram showing an example of the functional configuration of a plant management system 100. As shown in FIG.

[0019] The display control unit 110 causes the display device to display various types of information. The display device is a device operated by a user such as an operator or a field worker. The display device includes a display or the like capable of displaying various types of information. The display device is, for example, a personal computer connected to a display. Without being limited to this example, the display device may also be a portable terminal such as a smartphone, a tablet terminal, or a mobile phone.

[0020] The display control unit 110 displays a plant model on the display device. The plant model is an image showing equipment included in the plant. The plant model is, for example, an image showing the appearance of the equipment, such as the shape and structure of the equipment, in three dimensions. The plant model may, for example, be represented by different objects for each piece of equipment. For example, if a plant has piping and a tank as equipment, the piping and the tank may be represented by separate objects in the plant model. Data showing the plant model is stored in a storage device communicatively connected to the plant management device 100 or in a storage device included in the plant management device 100. The display control unit 110, for example, reads data from the storage device and displays the plant model on the display device.

[0021] In this way, the display control unit 110 causes the display device to display a plant model, which is an image of the equipment included in the plant. The display control unit 110 is an example of a display control means.

[0022] The receiving unit 120 receives an operation by a user. The user performs an operation on the plant model displayed on the display device. For example, the user performs an operation to select an object in the plant model. In this case, the receiving unit 120 receives the operation to select the object.

[0023] In this way, the receiving unit 120 receives an operation by the user on the plant model displayed on the display device. The receiving unit 120 is an example of a receiving means.

[0024] The display control unit 110 displays information corresponding to the operation received by the receiving unit 120 on the display device. For example, assume that the receiving unit 120 receives an operation to select an object of the plant model. The display control unit 110 displays, for example, operation information related to the equipment corresponding to the selected object. The operation information related to the equipment may be an operation menu related to the equipment or an input form that receives input from the user. Note that, without being limited to this example, the display control unit 110 may display, as the operation information related to the equipment, information indicating the operating status of the equipment, information indicating how to use the equipment, information indicating the specifications of the equipment, etc.

[0025] At this time, the display control unit 110 may display information corresponding to the operation depending on the user's role. Examples of user roles are a plant operator and a plant field worker. For example, the display control unit 110 changes the content to be displayed depending on whether the user is an operator or a field worker. At this time, the display control unit 110 may change the content to be displayed depending on whether the operation accepted by the accepting unit 120 is performed on a display device operated by an operator or a display device operated by a field worker. For example, when an object of a plant model is selected, the display control unit 110 displays on the display device an operation menu related to the equipment corresponding to the selected object. For example, when an object is selected by an operator, the display control unit 110 displays on the display device an operation menu including an item for requesting the field worker to inspect the equipment. Furthermore, when an object is selected by a field worker, the display control unit 110 displays on the display device an operation menu including an item for inputting information about an abnormality that has occurred in the equipment. Without being limited to this example, when an object is selected by an operator, the display control unit 110 may display an input form for inputting information for specifying the equipment corresponding to the selected object. When an object is selected by a field worker, the display control unit 110 may display an input form for inputting information regarding an abnormality that has occurred in the equipment corresponding to the selected object.

[0026] In this way, the display control unit 110 displays information corresponding to the user's role and operation on the display device operated by the user.

[0027] Next, an example of the operation of the plant management system 100 will be described with reference to Fig. 2. In this disclosure, each step in a flowchart is represented by a number assigned to the step, such as "S1".

[0028] 2 is a flowchart illustrating an example of the operation of the plant management system 100. The display control unit 110 displays a plant model, which is an image of equipment included in the plant, on a display device (S1). The reception unit 120 receives an operation by a user on the plant model displayed on the display device (S2). Then, the display control unit 110 displays information corresponding to the user's role and operation on the display device operated by the user (S3).

[0029] In this way, the plant management system 100 of the first embodiment displays a plant model, which is an image of equipment included in a plant, on a display device and accepts operations by a user for the plant model displayed on the display device. Then, the plant management system 100 displays information corresponding to the user's role and operation on the display device operated by the user.

[0030] Plant operators and on-site workers have different roles during inspections. Therefore, the tasks performed and the information required during inspections differ between operators and on-site workers. In response to this, the plant management system 100 can, for example, control the information to be displayed depending on the user, and can provide a user interface tailored to the user or prioritize the information required by the user. In other words, the plant management system 100 can support work during plant inspections.

[0031] Second Embodiment Next, a plant management system according to a second embodiment will be described. In the second embodiment, the plant management system 100 described in the first embodiment will be described in more detail. Note that some of the content that overlaps with the content described in the first embodiment will not be described again.

[0032] Fig. 3 is a diagram schematically illustrating an example of the configuration of a plant management system 1000. As shown in Fig. 3, the plant management system 1000 includes a plant management device 100. In the example of Fig. 3, the plant management system 1000 includes the plant management device 100, a display device 200, a display device 300, a storage device 400, a sensor 500, and an estimation device 600. The plant management device 100 can communicate with the display device 200, the display device 300, the storage device 400, the sensor 500, and the estimation device 600 via a wireless or wired network.

[0033] The display device 200 is a device operated by a field worker. The field worker performs on-site work related to plant equipment while checking information displayed on the display device 200, and inputs information using the display device 200. The display device 200 is, for example, a portable terminal such as a smartphone, a tablet terminal, a mobile phone, or a laptop-type personal computer. The display device 200 may also be a wearable terminal. Examples of wearable terminals include goggle-type terminals and wristwatch-type terminals. Hereinafter, the display device 200 will also be referred to as an operator terminal 200. The field worker will also be simply referred to as an operator.

[0034] The display device 300 is a device operated by an operator. The operator considers measures to be taken for the equipment while checking the information displayed on the display device 300, and inputs information using the display device 300. Hereinafter, the display device 300 is also referred to as an operator terminal 300.

[0035] The storage device 400 stores various types of information. For example, the storage device 400 stores data indicating a plant model, data acquired by the sensor 500, data related to the history of repairs performed on equipment, etc. The data stored in the storage device 400 will be described in detail later. The storage device 400 may be provided in the plant management device 100.

[0036] The sensor 500 is a sensor installed in the plant equipment. The sensor 500 is, for example, a temperature sensor, a pressure sensor, a voltage sensor, an optical sensor, etc., but is not limited to these examples. The sensor 500 may be any sensor that can measure information related to the status of the plant equipment. Note that a plurality of sensors 500 may be installed.

[0037] The estimation device 600 is a device that performs fault estimation for plant equipment based on various data.

[0038] Operators and workers share information via the plant management system 1000. For example, the worker inputs information that an abnormality has occurred in plant equipment by operating the worker terminal 200. The plant management system 100, for example, outputs the information input by the worker on the operator terminal 300. Then, the operator inputs, for example, instructions regarding the abnormality that has occurred by operating the operator terminal 300. The plant management system 100, for example, outputs the input instructions on the worker terminal 200. In this way, the plant management system 1000 supports two-way communication between operators and workers.

[0039] [Details of Plant Management System 1000] Fig. 4 is a block diagram showing an example of the functional configuration of the plant management system 1000. As shown in Fig. 4, the plant management system 100 is communicably connected to a worker terminal 200 (i.e., the display device 200), an operator terminal 300 (i.e., the display device 300), a storage device 400, a sensor 500, and an estimation device 600.

[0040] The worker terminal 200 includes an input unit 210 and an output unit 220. The input unit 210 receives input from a worker. For example, the input unit 210 receives a signal from an input device connected to the worker terminal 200. The input device is, for example, a device operated by a user, such as a mouse or a keyboard. Furthermore, without being limited to this example, if the worker terminal 200 has a touch panel, the input unit 210 may receive a signal generated by the user operating the touch panel. The output unit 220 outputs various information. For example, the output unit 220 displays a plant model on a display of the worker terminal 200. Note that the output unit 220 may be controlled by the plant management apparatus 100. A plurality of worker terminals 200 may be present. For example, the worker terminal 200 may be a terminal carried by each of a plurality of workers.

[0041] The operator terminal 300 includes an input unit 310 and an output unit 320. The input unit 310 is similar to the input unit 210 of the operator terminal 200. That is, the input unit 310 receives signals generated when a user of the operator terminal 300 operates an input device. The output unit 320 is similar to the output unit 220 of the operator terminal 200. That is, the output unit 320 displays various types of information on a display provided in the operator terminal 300. The output unit 320 may be controlled by the plant management system 100. A plurality of operator terminals 300 may be present.

[0042] The sensor 500 transmits sensor data to the plant management system 100. The sensor data is data related to values ​​measured by the sensor 500. For example, if the sensor 500 is a temperature sensor, the sensor data is data indicating the temperature measured by the temperature sensor. The sensor data also includes sensor identification information. The sensor identification information is information that identifies the sensor 500.

[0043] The plant management device 100 includes a display control unit 110, a receiving unit 120, and a sensor data management unit 130. The display control unit 110 includes an acquiring unit 1101 and a control unit 1102. The acquiring unit 1101 acquires data. For example, the acquiring unit 1101 acquires data stored in the storage device 400.

[0044] An example of data stored in the storage device 400 is data representing a plant model. The data representing the plant model is stored in advance in the storage device 400. The plant model includes a three-dimensional model representing the shape and structure of equipment within the plant. The three-dimensional model is generated, for example, based on point cloud data related to the equipment. For example, a measuring instrument photographs the inside of the plant. The measuring instrument is a device capable of 3D scanning, such as 3D-LiDAR (three-dimensional light detection and ranging). Point cloud data of the equipment within the plant is then created from the data photographed by the measuring instrument. Then, point cloud processing software converts the point cloud data to generate a three-dimensional model of the equipment. Note that the plant model may be created using various existing methods.

[0045] Another example of data stored in the storage device 400 is equipment information. The equipment information is information related to equipment included in the plant. The equipment information may include an operation log for the equipment, a repair history for the equipment, design drawings for the equipment, specifications for the equipment, a work procedure manual for the equipment, performance information for the equipment, and sensor trend values ​​for the equipment. The repair history is information indicating the history of repair work performed on the equipment. The design drawings are information indicating the shape, structure, dimensions, etc. of the equipment. The specifications are information including descriptions of the functions and characteristics, etc. of the equipment. The work procedure manual is information indicating the procedure for work to be performed on the equipment. The performance information is information indicating the actual measured values ​​of the performance of the equipment during operation. The sensor trend values ​​are information including sensor data measured by the sensor 500. The sensor trend values ​​are information managed by the sensor data management unit 130, which will be described later. In this way, the acquisition unit 1101 may acquire various data stored in the storage device 400.

[0046] The sensor data management unit 130 acquires sensor data from the sensors 500. The sensor data management unit 130 may periodically acquire the sensor data. The sensor data management unit 130 stores the acquired sensor data in the storage device 400. At this time, the sensor data management unit 130 may aggregate the sensor data for each piece of equipment in which the sensors 500 are installed and store the aggregated sensor data as a sensor trend value.

[0047] One or more sensors 500 are installed in one or more pieces of equipment within a plant. Therefore, the sensor data management unit 130 aggregates sensor data from the sensors 500 installed in the same piece of equipment. At this time, the sensor data management unit 130 associates the sensor data from the sensors installed in the same piece of equipment with equipment identification information that identifies the equipment and stores the associated data. For example, assume that a temperature sensor and a pressure sensor are installed in a cooling water pump. At this time, the sensor data management unit 130 associates the sensor data of the temperature sensor and the sensor data of the pressure sensor with equipment identification information. The sensor data management unit 130 may then store each piece of sensor data associated with the equipment identification information in the storage device 400 as a sensor trend value corresponding to the cooling water pump. In this case, information associating the sensor identification information with the equipment identification information of the equipment in which the sensor is installed is stored in advance in the storage device 400. The sensor data management unit 130 identifies the equipment identification information corresponding to the sensor identification information included in the acquired sensor data.

[0048] Furthermore, the acquiring unit 1101 may acquire data from the estimating device 600. Specifically, the acquiring unit 1101 acquires failure estimation data related to equipment included in the plant from the estimating device 600. The failure estimation data is information indicating a sign of equipment failure. The failure estimation data is generated by the estimating device 600.

[0049] The estimation device 600 includes an estimation unit 610. The estimation unit 610 estimates a failure of equipment included in the plant. The estimation unit 610 estimates the presence or absence of a sign of failure for the equipment based on, for example, sensor data of the equipment, an operation log, and the like stored in the storage device 400. The method for estimating the presence or absence of a sign of failure may be any of various existing methods.

[0050] For example, the estimation unit 610 estimates the presence or absence of a sign of failure using a rule-based method. At this time, if the value measured by the sensor 500 exceeds a predetermined threshold, the estimation unit 610 may estimate that there is a sign of failure in the equipment. Specifically, if the temperature measured by a temperature sensor installed in the equipment exceeds a temperature indicated as a threshold, the estimation unit 610 may estimate that there is a sign of failure in the equipment.

[0051] Furthermore, the estimation unit 610 may estimate the presence or absence of a sign of a failure using machine learning. In this case, a learning model that learns the relationship between sensor data, operation logs, etc., and equipment failures is generated in advance. The learning model receives the sensor data, operation logs, etc. as input, and outputs the presence or absence or probability of equipment failure. For example, the estimation unit 610 uses the learning model to obtain output information indicating the presence or absence of equipment failure. Then, if the output indicates that there is an equipment failure, the estimation unit 610 may estimate that there is a sign of equipment failure.

[0052] The estimation unit 610 transmits failure estimation data indicating whether or not there is a sign of a failure in the equipment to the plant management system 100.

[0053] The control unit 1102 of the plant management system 100 displays the data acquired by the acquisition unit 1101 on at least one of the worker terminal 200 and the operator terminal 300. For example, assume that the acquisition unit 1101 acquires data indicating a plant model. The control unit 1102 displays the plant model on the worker terminal 200 or the operator terminal 300. When displaying the plant model on the worker terminal 200, the control unit 1102 may, for example, control the output unit 220 of the worker terminal 200 to display the plant model.

[0054] The reception unit 120 receives an operation for the displayed plant model. Then, the control unit 1102 displays information corresponding to the operation received by the reception unit 120. The information corresponding to the received operation is referred to as operation information. Here, the control unit 1102 controls the operation information depending on the situation. Specific examples of the operation information will be described below with reference to the drawings.

[0055] FIG. 5 is an example of a plant model. In the example of FIG. 5, three cooling water pumps are shown as an example of equipment included in a plant. In this example, the plant model includes equipment objects and identification objects. The equipment objects are objects that represent the appearance of the equipment. For example, the equipment objects are three-dimensional models of the equipment. The equipment objects are shown as different objects for each piece of equipment. For example, the equipment objects may be shown in different colors for each piece of equipment. The identification objects are objects that are displayed to identify the equipment. In the example of FIG. 5, identification objects labeled "cooling water pump A," "cooling water pump B," and "cooling water pump C" are shown. Each identification object corresponds to a different equipment object. In this way, the plant model includes objects. Each of the objects is associated with a specific piece of equipment. Note that each of the objects may also be associated with a component of the equipment.

[0056] Here, it is assumed that the user performs an operation to select an identified object. That is, it is assumed that the user performs an operation to select equipment corresponding to the object. In this case, the control unit 1102 displays operation information related to the equipment corresponding to the selected object (that is, the selected equipment). For example, the control unit 1102 displays an operation menu related to the equipment corresponding to the selected object. At this time, the control unit 1102 displays different operation menus depending on the role of the user who performed the operation. That is, the control unit 1102 displays different operation menus depending on whether the user who performed the operation is an operator or a worker.

[0057] FIG. 6A is a first example of operation information. More specifically, FIG. 6A is an example of operation information when the user is a worker. For example, the worker touches an identification object of cooling water pump A displayed on the worker terminal 200. At this time, the receiving unit 120 receives the operation of touching the identification object as an operation to select cooling water pump A. Then, the control unit 1102 displays an operation menu corresponding to the worker on the worker terminal 200. In the example of FIG. 6A, an operation menu including items "Input Abnormality Report," "Work Procedure Manual," "Device Operation Manual," "Device Specifications," and "Sensor Trend Value" is displayed. The processing when an item on the operation menu is selected will be described later.

[0058] For example, the item "Input Abnormality Report" is an item for accessing information for reporting an abnormality that has occurred in cooling water pump A. Furthermore, for example, the item "Equipment Operation Manual" is an item for accessing the operation manual for cooling water pump A. Operators perform field work on plant equipment. Therefore, the operation menu corresponding to operators includes, for example, items for accessing information required for field work and information for reporting an abnormality in the equipment. Note that the information included in the operation menu is not limited to this example. The operation menu may further include items for accessing instructions from operators and design drawings of the equipment. For example, when instructions are input by an operator, the control unit 1102 may include, in the operation menu, an item for accessing the instructions.

[0059] 6B is a second example of operation information. For example, an operator touches the identification object of cooling water pump A displayed on the operator terminal 300. At this time, the reception unit 120 receives the operation of touching the identification object as an operation to select cooling water pump A. Then, the control unit 1102 displays an operation menu corresponding to the operator on the operator terminal 300. In the example of FIG. 6B, an operation menu including items such as "Refer to abnormality report," "Input instruction," "Repair history," "Fault estimation data," and "Sensor trend value" is displayed.

[0060] For example, the "reference to abnormality report" item is an item for accessing information input by a worker, which is information regarding an abnormality that has occurred in cooling water pump A. Furthermore, for example, the "input instructions" item is an item for accessing information for an operator to input instructions to the worker. The operator identifies the abnormality that has occurred, formulates a response to the abnormality, and gives instructions to the worker. Therefore, the operation menu corresponding to the operator includes items for accessing, for example, information for checking the report regarding the abnormality from the worker, information necessary to formulate a response to the abnormality, and information for giving instructions to the worker. Note that the information included in the operation menu is not limited to this example. For example, the operation menu may include items for accessing a work procedure manual, performance information, etc.

[0061] The operation menus displayed when the user is an operator and when the user is a worker are not limited to the above example. For example, the control unit 1102 may display the operation menu so that the order of items in the operation menu differs depending on the user's role. In this case, items for accessing information required by the user are displayed at the top.

[0062] In this way, the control unit 1102 displays operation information related to the specific equipment indicated by the selected object on the display device operated by the user. At this time, the operation information related to the specific equipment differs depending on whether the user's role is an operator or a worker.

[0063] Various methods may be used to identify the role of the user who performed the operation. For example, the reception unit 120 may identify the role of the user by identifying the type of display device on which the operation was performed. For example, if the operation was performed using the operator terminal 200, the reception unit 120 may identify the role of the user as a worker. If the operation was performed using the operator terminal 300, the reception unit 120 may identify the role of the user as an operator. Furthermore, the reception unit 120 may identify the role of the user based on the type of user who performed the operation, rather than the type of display device on which the operation was performed. For example, a user logs in to the plant management system 1000 to display a plant model on a display device. When logging in, the user inputs user identification information that identifies the user as login information. The user identification information is an example of information indicating the type of user. The user identification information is associated with information indicating the user's role. The reception unit 120 may identify whether the user who performed the operation is an operator or a worker, based on the user identification information input at the time of login. In this way, the control unit 1102 controls the information corresponding to the operation to be different based on the type set depending on whether the user's role is a plant operator or a plant field worker.

[0064] Next, a process when an item in the operation menu is selected will be described. The accepting unit 120 accepts an operation to select an item. The control unit 1102 displays information corresponding to the selected item.

[0065] In the example of FIG. 6A , assume that the operator selects the “Input Abnormality Report” option. At this time, the reception unit 120 receives the selection of the option. Then, the display control unit 110 displays an input form on the operator terminal 200, allowing the operator to input information about the abnormality. FIG. 7A is a diagram illustrating a first example of the input form. In the example of FIG. 7A , an input form related to cooling water pump A is illustrated. The reception unit 120 receives input of information about the abnormality from the operator via the input form. At this time, the reception unit 120 may receive input of at least one of text, audio, and image. For example, in the example of FIG. 7A , when the operator selects to start recording, recording is performed using a microphone included in the operator terminal 200. As a result, the plant management system 100 can capture audio including the abnormal sound, for example, when an abnormal sound is occurring in the equipment. Furthermore, for example, when the operator selects to start capturing an image, the camera included in the operator terminal 200 is activated and captures an image. As a result, the plant management system 100 can capture an image showing the exterior of the equipment in which the abnormality is occurring.

[0066] The receiving unit 120 stores the input information about the abnormality in the storage device 400. At this time, the receiving unit 120 stores the input information about the abnormality in association with the equipment identification information of the selected equipment. In this way, the receiving unit 120 may receive input of information about the abnormality of specific equipment from a display device operated by an operator.

[0067] Furthermore, in the example of FIG. 6A , assume that the worker selects the "sensor trend value" item. At this time, the receiving unit 120 receives the item selection operation. Then, the display control unit 110 displays the sensor trend value related to the selected equipment on the worker terminal 200. In this case, the acquiring unit 1101 acquires the sensor trend value of the selected equipment, i.e., cooling water pump A, from the storage device 400. Then, the control unit 1102 displays the acquired sensor trend value on the worker terminal 200. FIG. 7B is a diagram showing an example of a sensor trend value. In the example of FIG. 7B , information indicating the sensor trend value of the temperature sensor related to cooling water pump A is displayed. In this way, the display control unit 110 may display information related to the selected equipment.

[0068] In the example of FIG. 6B , it is assumed that the operator selects the item "See Abnormality Report." At this time, the reception unit 120 receives the selection of the item. Then, the display control unit 110 displays the information about the abnormality input by the operator on the operator terminal 300. In this case, the acquisition unit 1101 acquires information about the abnormality of cooling water pump A from the storage device 400. Then, the control unit 1102 displays the acquired information about the abnormality on the operator terminal 300.

[0069] FIG. 7C is a diagram showing an example of information related to an anomaly. The example of FIG. 7C shows information related to an anomaly of cooling water pump A, which was input in the example of FIG. 7A. More specifically, the control unit 1102 displays information including text, audio, and images input by the operator. In the example of FIG. 7C, the input audio is displayed as an audio memo. The input image is displayed as a photographed image. At this time, the control unit 1102 may highlight and display an object indicating the equipment that is the subject of the information related to the anomaly. For example, the control unit 1102 may add color to the equipment object of cooling water pump A, thicken the outline of the equipment object, or blink the equipment object. The operator checks the information related to the anomaly to formulate a response to the anomaly.

[0070] Here, the display control unit 110 may display information about the specific equipment in addition to information about the abnormality of the specific equipment. Specifically, the acquisition unit 1101 acquires, in addition to information about the abnormality of the cooling water pump A, at least one of the following from the storage device 400: a repair history of the cooling water pump A, a sensor trend value of the sensor 500 related to the cooling water pump A, and failure estimation data for the cooling water pump A. The control unit 1102 may then display the acquired information about the cooling water pump A on the operator terminal 300. In this manner, the display control unit 110 may display, on a display device operated by the operator, information about the abnormality input by the worker and information about the specific equipment. In this case, the information about the specific equipment may include any of the repair history of the specific equipment, the sensor trend value of the sensor related to the specific equipment, and failure estimation data indicating a sign of a failure of the specific equipment. This allows the operator to formulate a response to the abnormality while taking various data into consideration.

[0071] Furthermore, in the example of FIG. 6B , assume that the operator selects the “Instruction Input” option. At this time, the reception unit 120 receives the selection of the option. Then, the display control unit 110 displays, on the operator terminal 300, an input form in which instruction information indicating the details of the work to be performed on the equipment can be input. FIG. 7D is a diagram showing a second example of the input form. The example of FIG. 7D shows an input form regarding instructions for work to be performed on cooling water pump A. The reception unit 120 receives input of instruction information from the operator via the input form. The example of FIG. 7D shows information prompting the operator to input work details and text. As the work details, for example, a work procedure manual corresponding to the work is set. Note that this example is not limiting, and the reception unit 120 may also receive input of voice and image. The reception unit 120 stores the input instruction information in the storage device 400. At this time, the reception unit 120 associates and stores the equipment identification information of the selected equipment with the input instruction information.

[0072] The instruction information is displayed on the worker terminal 200 by the display control unit 110. When displaying the instruction information on the worker terminal 200, the display control unit 110 may highlight the object of the equipment that is the target of the work indicated in the instruction information. For example, assume that the instruction information is for work on cooling water pump A. In this case, the control unit 1102 may add color to the equipment object representing cooling water pump A, thicken the outline of the equipment object, or blink the equipment object.

[0073] In this way, the receiving unit 120 may receive input of instruction information including the details of the work from a display device operated by a plant operator. Furthermore, the display control unit 110 may display the input instruction information on a display device operated by a field worker of the plant.

[0074] [Operation Example 1 of Plant Management Apparatus 100] Next, an example of the operation of the plant management apparatus 100 will be described with reference to Fig. 8. In this operation example, the operation when acquiring sensor data from the sensor 500 will be described.

[0075] 8 is a flowchart illustrating a first example of the operation of the plant management system 100. The sensor data management unit 130 acquires sensor data from the sensor 500 (S101). At this time, the sensor data management unit 130 acquires the sensor data, for example, periodically. Then, the sensor data management unit 130 stores the acquired sensor data in the storage device 400 (S102). At this time, the sensor data management unit 130 associates the acquired sensor data with equipment identification information of the equipment in which the sensor is installed, and stores the associated sensor data as a sensor trend value.

[0076] [Second Example of Operation of Plant Management Apparatus 100] Next, another example of operation of the plant management apparatus 100 will be described with reference to Fig. 9. In this example of operation, an operation will be described in which a user operates a display device operated by the user.

[0077] 9 is a flowchart illustrating a second example of the operation of the plant management system 100. First, the acquisition unit 1101 acquires data indicating a plant model from the storage device 400 (S201). Then, the control unit 1102 displays the plant model on the display device (S202).

[0078] The reception unit 120 receives an operation on the plant model by the user (S203). For example, the reception unit 120 receives an operation to select an object included in the plant model. Then, the control unit 1102 displays operation information according to the role of the user (S204). For example, the control unit 1102 displays different operation menus depending on whether the user is an operator or a worker.

[0079] The receiving unit 120 also receives an operation for the operation information (S205). For example, the receiving unit 120 receives an operation to select an item from an operation menu. Then, the control unit 1102 displays information corresponding to the operation (S206). For example, if an item for reporting an abnormality is selected, the control unit 1102 displays an input form for inputting information about the abnormality. Note that, if an item for equipment information such as a sensor trend value is selected in the processing of S205, the acquisition unit 1101 acquires the equipment information from the storage device 400. Then, the control unit 1102 displays the equipment information.

[0080] [Example of Operation of Plant Management System 1000] Next, an example of a specific operation of the plant management system 1000 will be described with reference to Figures 10 and 11. This example of operation shows an example of communication that takes place between the worker terminal 200 and the operator terminal 300 when an abnormality occurs in the equipment.

[0081] 10 is a sequence diagram illustrating a first example of the operation of the plant management system 1000. More specifically, FIG. 10 illustrates an example of the operation of the plant management system 1000 when an operator operates the operator terminal 200. First, the acquisition unit 1101 acquires data indicating a plant model from the storage device 400 (S301). Then, the control unit 1102 causes the operator terminal 200 to display the plant model (S302).

[0082] The plant model is displayed on the operator terminal 200 via the output unit 220. Then, an object included in the plant model is selected in the input unit 210 (S303).

[0083] The receiving unit 120 receives an operation to select an object (S304). The control unit 1102 displays an operation menu according to the user's role (S305). In this example, since the user is a worker, the control unit 1102 displays the operation menu shown in FIG. 6A on the worker terminal 200.

[0084] At the operator terminal 200, an operation menu is displayed via the output unit 220. Then, the item "input abnormality report" is selected at the input unit 210 (S306).

[0085] The accepting unit 120 accepts an operation to select an item (S307). Since the item "Input abnormality report" has been selected, the control unit 1102 displays an input form for inputting information about the abnormality (S308).

[0086] An input form is displayed on the operator terminal 200 via the output unit 220. Then, information about the abnormality is input via the input unit 210 (S309).

[0087] The receiving unit 120 acquires information about the abnormality and stores the information about the abnormality in the storage device 400 (S310).

[0088] Fig. 11 is a sequence diagram illustrating a second example of the operation of the plant management system 1000. More specifically, Fig. 11 illustrates an example of the operation of the plant management system 1000 when an operator operates the operator terminal 300. First, the acquisition unit 1101 acquires data indicating a plant model from the storage device 400 (S401). Then, the control unit 1102 causes the operator terminal 300 to display the plant model (S402).

[0089] The plant model is displayed on the operator terminal 300 via the output unit 320. Then, an object included in the plant model is selected in the input unit 310 (S403).

[0090] The reception unit 120 receives an operation to select an object (S404). The control unit 1102 displays an operation menu according to the user's role (S405). In this example, since the user is an operator, the control unit 1102 displays the operation menu shown in FIG. 6B on the operator terminal 300.

[0091] On the operator terminal 300, an operation menu is displayed via the output unit 320. Then, the item "Refer to abnormality report" is selected on the input unit 310 (S406).

[0092] The receiving unit 120 receives an operation to select an item (S407). Since the "Refer to Abnormality Report" item has been selected, the acquiring unit 1101 acquires information about the abnormality (S408). Then, the control unit 1102 displays the acquired information about the abnormality (S409). At this time, the display control unit 110 may also display information about the equipment in which the abnormality occurred (i.e., the equipment corresponding to the selected object). For example, the acquiring unit 1101 may acquire equipment failure estimation data from the storage device 400. Then, the control unit 1102 may display the acquired failure estimation data.

[0093] Thereafter, the "input instruction" item is selected in the operation menu by the input unit 310 of the operator terminal 300 (S410). That is, the operator selects the "input instruction" item.

[0094] The reception unit 120 receives an operation to select an item (S411). Since the "Instruction input" item has been selected, the control unit 1102 displays an input form in which instruction information indicating the content of the work to be performed on the equipment can be input (S412).

[0095] An input form is displayed on the operator terminal 300 via the output unit 320. Then, instruction information is input into the input unit 310 (S413).

[0096] The receiving unit 120 receives the instruction information and stores the information about the abnormality in the storage device 400 (S414).

[0097] The instruction information is displayed on the operator terminal 200 in the same manner as the information regarding the abnormality.

[0098] In this way, the plant management system 100 of the second embodiment displays a plant model, which is an image of equipment included in a plant, on a display device and accepts operations by a user for the plant model displayed on the display device. Then, the plant management system 100 displays information corresponding to the user's role and operation on the display device operated by the user.

[0099] As an example, the plant management device 100 of the second embodiment accepts an operation to select an object included in a plant model, and displays operation information related to a specific facility indicated by the selected object on a display device operated by the user. At this time, the operation information related to the specific facility differs depending on whether the user's role is a plant operator or a field worker of the plant.

[0100] Plant employees have different roles. Therefore, the tasks performed and the information required during inspections differ between operators and field workers. In response to this, the plant management system 100 can, for example, control the information displayed depending on the user, and can provide a user interface tailored to the user or prioritize the information required by the user. In other words, the plant management system 100 can support work during plant inspections.

[0101] Furthermore, the plant management system 100 of the second embodiment accepts input of information relating to an abnormality of a specific piece of equipment from a display device operated by a field worker of the plant, and causes the display device operated by the plant operator to display the input information relating to the abnormality and information relating to the specific piece of equipment. In this way, the plant management system 100 can provide the operator with information relating to an abnormality that has occurred in the specific piece of equipment, which has been input by the field worker.

[0102] At this time, the plant management system 100 can also provide the operator with information related to the specific equipment. The information related to the specific equipment may be, for example, at least one of the following: a repair history of the specific equipment, a sensor trend value of a sensor related to the specific equipment, and failure estimation data indicating a sign of a failure of the specific equipment. This allows the plant management system 100 to preferentially provide the operator with information necessary to formulate a response to the abnormality.

[0103] Furthermore, the plant management system 100 of the second embodiment receives instruction information including the details of a task from a display device operated by a plant operator, and displays the input instruction information on a display device operated by a plant field worker. This allows the plant management system 100 to provide the field worker with the instructions regarding the task input by the operator.

[0104] [Variation 1] The plant model does not have to include a three-dimensional model showing the shape and structure of the equipment within the plant. For example, the plant model may include a photographed image of the equipment. In this case, the part of the equipment that appears in the photographed image is the equipment object. Furthermore, the identification object is superimposed on the photographed image.

[0105] [Modification 2] The estimation device 600 may be included in the plant management system 100. That is, the plant management system 100 may estimate whether or not there is a sign of a failure in the equipment.

[0106] Furthermore, the sensor data management unit 130 does not have to be included in the plant management apparatus 100. That is, the sensor data management unit 130 may be included in an external device different from the plant management apparatus 100. In this case, the external device is connected to at least the sensor 500 and the storage device 400 so as to be able to communicate with them.

[0107] [Variation 3] The display control unit 110 may display objects included in the plant model in various modes. For example, the control unit 1102 may display objects representing equipment by assigning different colors to each piece of equipment. Furthermore, for example, pipes, tanks, and the like contain raw materials. The control unit 1102 may display the objects by assigning colors to the objects representing the equipment according to the type of raw material present therein.

[0108] Furthermore, the plant equipment may include equipment for which work is required by law. For example, there may be equipment for which periodic inspection work is required by law. The display control unit 110 may apply color to objects that indicate equipment for which work is required by law.

[0109] [Variation 4] In the above embodiment, an example has been described in which the operation information displayed when an object included in the plant model is selected is an operation menu. The operation information displayed when an object is selected is not limited to an operation menu. For example, when an object is selected on the operator terminal 200, the display control unit 110 may display an input form such as that shown in FIG. 7A. Furthermore, for example, when an object is selected on the operator terminal 300, the display control unit 110 may display an input form such as that shown in FIG. 7D.

[0110] 10 and 11 , an example has been described in which the plant management system 100 starts with an operator inputting information related to an anomaly, and then outputs various pieces of information to the operator terminal 300. However, the plant management system 100 may also start with an operator inputting instruction information, and then output various pieces of information to the operator terminal 200.

[0111] Third Embodiment Next, a plant management system according to a third embodiment will be described. In the third embodiment, further functions of the plant management system will be described. Note that some of the content that overlaps with the content described in the first and second embodiments will not be described.

[0112] [Details of Plant Management System 1001] Fig. 12 is a block diagram showing an example of the functional configuration of the plant management system 1001. As shown in Fig. 12, the plant management system 1001 includes a plant management system 101 instead of the plant management system 100 shown in Fig. 4. That is, the plant management system 1001 includes the plant management system 101, a worker terminal 200 (i.e., the display device 200), an operator terminal 300 (i.e., the display device 300), a storage device 400, a sensor 500, and an estimation device 600. The plant management system 101 can communicate with the display device 200, the display device 300, the storage device 400, the sensor 500, and the estimation device 600 via a wireless or wired network.

[0113] The plant management device 101 includes a display control unit 110 , a receiving unit 120 , a sensor data management unit 130 , and a notification unit 140 .

[0114] When a user inputs something, the notification unit 140 notifies the user who made the input or another user. Specifically, when a user inputs something, the notification unit 140 transmits notification information to a display device operated by the user who made the input or a display device operated by another user. The notification unit 140 is an example of a notification means.

[0115] For example, assume that information regarding an abnormality is input to the operator terminal 200. The notification unit 140 transmits the notification information to the operator terminal 300. In this case, the notification information includes information indicating that information regarding the abnormality has been input. The notification information may further include equipment identification information of the target equipment and user identification information of the operator who made the input.

[0116] FIG. 13 is a diagram illustrating an example of notification information. For example, when information regarding an abnormality is input to the operator terminal 200, the notification unit 140 displays the notification information on the operator terminal 300 by superimposing it on the plant model. In the example of FIG. 13, an object stating "An abnormality has been reported regarding cooling water pump A" is displayed. In this manner, the notification unit 140 may display the object indicating the notification information by superimposing it on the plant model. In this case, the notification unit 140 transmits the notification information to the operator terminal 300 after, for example, the processing of S310 in FIG. 10 . In this way, the plant management device 101 can prompt the operator to check the information regarding the abnormality.

[0117] Furthermore, for example, when an object indicating notification information is selected by an operator, the display control unit 110 may display information related to an abnormality. Here, it is assumed that an object of equipment that is not the subject of information related to an abnormality is displayed on the operator terminal 300. At this time, when an object of notification information is selected, the display control unit 110 may perform control so that an object of equipment that is the subject of information related to an abnormality is displayed on the operator terminal 300.

[0118] Similarly, assume that instruction information is input to the operator terminal 300. At this time, the notification unit 140 transmits the notification information to the worker terminal 200. The notification information includes information indicating that the instruction information has been input. The notification information may further include equipment identification information of the target equipment and user identification information of the operator who made the input. For example, when instruction information is input to the operator terminal 300, the notification unit 140 superimposes the notification information on the plant model and displays it on the worker terminal 200. In this case, the notification unit 140 transmits the notification information to the worker terminal 200 after, for example, the processing of S414 in FIG. 11 . This allows the plant management device 101 to prompt the worker to confirm the instruction information.

[0119] 13 , the display control unit 110 may perform control so that instruction information is displayed when an object of the displayed notification information is selected. Assume that an object of equipment that is not the target of the instruction information is displayed on the worker terminal 200. If the object of the notification information is selected at this time, the display control unit 110 may perform control so that the object of the equipment that is the target of the instruction information is displayed on the worker terminal 200.

[0120] Furthermore, the notification unit 140 may transmit notification information indicating that instruction information has been input to a predetermined destination. For example, the notification unit 140 transmits the notification information based on person in charge information. The person in charge information includes information indicating the worker in charge of each piece of equipment. The person in charge information is stored in the storage device 400. FIG. 14 is a diagram showing an example of person in charge information. For example, assume that the equipment identification information of the equipment that is the target of the work included in the instruction information is "001". In this case, the notification unit 140 notifies worker X, who is in charge of the equipment with equipment identification information "001". In other words, the notification unit 140 transmits the instruction information to a display device operated by worker X.

[0121] In this way, the notification unit 140 may notify the instruction information to a display device operated by one of the multiple on-site workers in charge of the equipment that is the target of the work. As a result, the plant management device 101 notifies the person in charge of the equipment, thereby providing support for quickly progressing the work.

[0122] At this time, the notification unit 140 may also notify other personnel of the instruction information. For example, the notification unit 140 may send a notification to personnel in charge of equipment related to the equipment that is the target of the work. Equipment related to the equipment that is the target of the work is also referred to as related equipment. For example, related equipment is equipment connected to the equipment that is the target of the work. However, related equipment may also be equipment that is affected by an abnormality that occurs in the equipment that is the target of the work. In the example of FIG. 14 , equipment identification information "001" is associated with related equipment "002." For example, assume that the equipment identification information of the equipment that is the target of the work, included in the instruction information, is "001." In this case, the notification unit 140 notifies worker X, who is the person in charge of the equipment with equipment identification information "001," and worker Y, who is the person in charge of the equipment with equipment identification information "002." That is, the notification unit 140 transmits the instruction information to the display device operated by worker X and the display device operated by worker Y.

[0123] In this way, the notification unit 140 may notify the instruction information to a display device operated by another person in charge of equipment related to the equipment being worked on. Depending on the results of the work, predetermined work may be performed not only on the equipment being worked on but also on related equipment. By notifying the person in charge of the related equipment of the instruction information, the plant management device 101 can support rapid information sharing.

[0124] The notification unit 140 may transmit notification information based on qualification information, without being limited to the above example. Qualification information is information that associates workers with the qualifications held by the workers. The qualification information is stored in the storage device 400. FIG. 15 is a diagram showing an example of qualification information. For example, worker X holds the qualification "ABC", and worker Y holds the qualification "ABC" and the qualification "DEF".

[0125] Assume that the work included in the instruction information is work that can only be performed by a person with a specific qualification. In this case, the notification unit 140 notifies a worker with the specific qualification. For example, assume that the work included in the instruction information is work that can only be performed by a person with the qualification "DEF." For example, the notification unit 140 notifies worker Y, who holds the qualification "DEF," of the instruction information based on the qualification information in FIG. 15 .

[0126] In this way, the notification unit 140 may notify the display device operated by a field worker who has the necessary qualifications for the work, among multiple field workers. This allows the plant management device 101 to notify the appropriate worker of the instruction information when instructing work that requires qualifications.

[0127] Furthermore, the notification unit 140 may transmit notification information to the operator terminal 300 when instruction information is input to the operator terminal 300. Typically, work procedures are provided for tasks performed on plant equipment. That is, work procedures corresponding to each task are stored in advance in the storage device 400. For example, when inputting instruction information, the operator sets a work procedure as the task content. Here, the operator may want to request a task that is different from the usual task from a worker. That is, the operator may want to request a task for which no work procedure exists. In this case, a new work procedure needs to be issued. Therefore, when instruction information is input, if no work procedure has been set for the task content included in the instruction information, the notification unit 140 transmits notification information to the operator terminal 300 prompting the issuance of a work procedure. For example, in the example of FIG. 11 , the notification unit 140 transmits notification information to the operator terminal 300 prompting the issuance of a work procedure after S413.

[0128] In this way, when a work procedure manual for a task in the input instruction information has not been set, the notification unit 140 may send a notification to a display device operated by the operator to prompt the operator to issue a work procedure manual for the task. This allows the plant management device 101 to prevent forgetting to issue a work procedure manual.

[0129] Furthermore, when instruction information is input to the operator terminal 300, the notification unit 140 may transmit notification information including notes regarding the equipment to be worked on to the operator terminal 300. The equipment included in the plant includes equipment for which work methods are regulated by law. For example, some equipment may require only personnel holding a specific qualification to work on it, or may require approval from a person holding a specific position or application to a specific institution to perform the work. For example, if a person without the specific qualification performs work that can only be performed by a person holding the specific qualification, it may be a violation of the law. Therefore, when equipment requiring legally compliant measures is selected, the notification unit 140 may send notification information to the operator including notes indicating that legally compliant measures are required.

[0130] FIG. 16 is a diagram illustrating another example of notification information. In the example of FIG. 16 , notification information including a caution indicating that legally compliant measures are required is displayed. In this example, the notification information including the caution is displayed when an input form for inputting instruction information is displayed. In this manner, the notification unit 140 may notify the operator of the notification information when the receiving unit 120 receives an operation to select an item from an operation menu for inputting instruction information and the equipment in question is equipment for which work methods are specified by law. Furthermore, without being limited to this example, the notification unit 140 may notify the operator of the notification information when the receiving unit 120 receives an operation to select an object and the equipment corresponding to the selected object is equipment for which work methods are specified by law.

[0131] In this way, the notification unit 140 may send a notification to a display device operated by an operator indicating that legally compliant measures are required depending on the type of equipment to be worked on. This allows the plant management device 101 to reduce the possibility of taking measures that violate the law.

[0132] [Variation 6] In the above embodiment, an example has been described in which the field worker is a human, but the field worker may also be a robot. The robot may be a patrol inspection robot that inspects equipment. The robot may further include a function for taking photographs and a function for estimating faults.

[0133] For example, when an operator inputs instruction information, the robot performs work on the target equipment based on the instruction information. Then, the robot transmits work results, which are information about the results of the work, to the plant management device 101. The work results include, for example, sensor values ​​when the work was performed and images of the equipment taken when the work was performed. The work results may also include failure estimation data. In this case, the robot estimates, for example, the degree of rust progression and the presence or absence of signs of abnormalities such as liquid leakage from the images taken of the equipment.

[0134] The reception unit 120 stores the work results in the storage device 400. Then, the notification unit 140 transmits notification information indicating that the work has been completed to the operator terminal 300.

[0135] <Fourth embodiment> Next, a plant management system according to a fourth embodiment will be described. In the fourth embodiment, further functions of the plant management system will be described. Note that some of the content that overlaps with the content described in the first, second, and third embodiments will not be described.

[0136] First, an example of a situation in which the plant management system 1002 in this embodiment is used will be described. FIG. 17 is a diagram schematically illustrating an example of a situation in which the plant management system 1002 is used. In the example of FIG. 17 , markers are installed on equipment. The worker terminal 201 has a camera function. A field worker uses the worker terminal 201 to capture an image including the markers. The worker terminal 201 extracts information from the captured image and transmits the extracted information to the plant management device 102. The plant management device 102 controls the display of the plant model based on the extracted information.

[0137] [Details of Plant Management System 1002] Fig. 18 is a block diagram showing an example of the functional configuration of the plant management system 1002. As shown in Fig. 18, the plant management system 1002 includes a plant management system 102 instead of the plant management system 100 shown in Fig. 4. That is, the plant management system 1002 includes the plant management system 102, an operator terminal 201 (i.e., the display device 201), an operator terminal 300 (i.e., the display device 300), a storage device 400, a sensor 500, and an estimation device 600. The plant management system 102 can communicate with the display device 201, the display device 300, the storage device 400, the sensor 500, and the estimation device 600 via a wireless or wired network.

[0138] The operator terminal 201 includes an input unit 210, an output unit 220, and an extraction unit 230. The input unit 210 includes a camera function. That is, the input unit 210 captures an image. The input unit 210 then generates a captured image. The extraction unit 230 extracts information from a marker included in the captured image. Information extracted from the marker is also referred to as extracted information. The marker is, for example, installed on a facility. This example is not limiting, and the marker may be installed near the facility. The marker may be different for each facility. The marker is, for example, a two-dimensional code, but is not limited thereto. For example, the marker may be a symbol indicated by a different shape or color for each facility. The extracted information includes information indicating the facility on which the marker is installed. For example, assume that a marker is installed on a facility. In this case, the extraction unit 230 extracts extracted information including information indicating the facility from the captured image including the marker. In this way, the extraction method includes information indicating at least one facility included in the plant. Then, the extraction unit 230 transmits the extracted information to the plant management device 102 .

[0139] The plant management device 102 includes a display control unit 111 , a reception unit 121 , a sensor data management unit 130 , and a notification unit 140 .

[0140] The reception unit 121 receives the extracted information from the worker terminal 201. More specifically, the reception unit 121 receives the extracted information, which is information extracted from a marker included in an image captured by a display device operated by a field worker.

[0141] The display control unit 111 includes an acquisition unit 1101 and a control unit 1112. The control unit 1112 identifies the equipment indicated by the extracted information. Then, the control unit 1112 displays a plant model indicating the identified equipment on the operator terminal 201. In this way, the display control unit 111 displays the plant model indicating the equipment indicated by the extracted information on a display device operated by a field operator.

[0142] Here, it is assumed that an operator has given an instruction regarding a work to a worker, that is, instruction information has been input to the operator terminal 300. At this time, the control unit 1112 may cause the operator terminal 201 to display information indicating whether or not the equipment indicated by the extracted information is the equipment that is the target of the work included in the instruction information.

[0143] For example, instruction information is displayed on the operator terminal 201. At this time, the input unit 210 of the operator terminal 201 activates a photography screen. Then, the input unit 210 takes a photograph in response to an operation by the operator. The extraction unit 230 transmits the extraction information and equipment identification information of the equipment that is the target of the work, which is included in the instruction information. Assume that the instruction information is input by the operator. At this time, the control unit 1112 displays a plant model that indicates the equipment indicated by the extraction information, and also displays information indicating whether the equipment indicated by the extraction information is the equipment that is the target of the work.

[0144] FIG. 19 is a diagram illustrating an example of a display based on extraction information. The example in FIG. 19 illustrates a case where the extraction information includes information indicating cooling water pump B and the target of work is cooling water pump C. In this case, the control unit 1112 displays an object indicating cooling water pump B. The control unit 1112 also displays an object including the statement, "Cooling water pump B is not a target of work." Meanwhile, the control unit 1112 highlights the object of cooling water pump C, which is the target of work. In the example in FIG. 19 , the object of cooling water pump C is indicated by hatching. This example is not limiting. The control unit 1112 may also color the object of the equipment that is the target of work, thicken the outline of the object, or blink the object. Furthermore, the control unit 1112 may display the object of the equipment indicated by the extraction information in a manner different from the object of the equipment that is the target of work.

[0145] In this way, the display control unit 111 may display information indicating whether or not the equipment indicated by the extracted information is the equipment that is the target of work on a display device operated by a field worker.

[0146] [Example of Operation of Plant Management System 1002] Next, an example of a specific operation of the plant management system 1002 will be described with reference to Fig. 20. In this example of operation, an example will be described in which the plant management device 102 displays a plant model on the operator terminal 201 based on the extracted information. In this example of operation, it is assumed that instruction information has been input to the operator terminal 300.

[0147] 20 is a sequence diagram illustrating an example of the operation of the plant management system 1002. First, the notification unit 140 transmits notification information indicating that instruction information has been input to the operator terminal 201 (S501). Then, an object indicating the notification information is selected in the input unit 210 of the operator terminal 201 (S502). The reception unit 121 receives an operation to select the object (S503). Then, the control unit 1112 displays the instruction information (S504).

[0148] Then, the camera of the operator terminal 201 is activated, and the input unit 210 captures an image of the marker (S505). The extraction unit 230 extracts information from the captured image including the marker (S506). The extraction unit 230 then transmits the extracted information and equipment identification information based on the instruction information to the plant management device 102 (S507). The equipment identification information based on the instruction information is equipment identification information of equipment that is the target of the work included in the instruction information.

[0149] The control unit 1112 identifies a facility based on the extracted information (S508). Then, the control unit 1112 displays the plant model (S509). At this time, the control unit 1112 displays an object indicating the identified facility, and also displays information indicating whether the identified facility is a facility that is the target of work, on the operator terminal 201.

[0150] In this way, the plant management device 102 of the fourth embodiment accepts extracted information, which is information extracted from an image captured by a display device operated by a field worker, and displays a plant model indicating the equipment indicated by the extracted information on the display device operated by the field worker. In this case, the extracted information is information extracted from markers included in the image. The extracted information also includes information indicating at least one of the pieces of equipment included in the plant. A plant has a large number of pieces of equipment. Therefore, there is a risk that the worker will not know which object on the plant model corresponds to the equipment he or she is visually observing. In response to this, the plant management device 102 can allow the worker to confirm the plant model corresponding to the equipment he or she is visually observing.

[0151] Furthermore, the plant management device 102 of the fourth embodiment may display information indicating whether or not the equipment indicated by the extracted information is the equipment to be worked on, on a display device operated by a field worker. As described above, there is a large number of pieces of equipment in a plant, and therefore, the worker may not know which piece of equipment is the target of the work included in the instruction information. In response to this, the plant management device 102 displays information indicating whether or not the equipment indicated by the extracted information is the equipment to be worked on, thereby making it possible to present to the worker which piece of equipment is the target of the work included in the instruction information.

[0152] [Variation 7] The extraction unit 230 may be included in the plant management device 102. In this case, the input unit 210 transmits a captured image including a marker and equipment identification information based on the instruction information to the plant management device 102. The extraction unit 230 of the plant management device 102 extracts the extracted information from the captured image. Then, the control unit 1112 displays the plant model based on the extracted information extracted by the extraction unit 230.

[0155] The storage device 94 stores a program (computer program) 98. The processor 91 executes the program 98 of the plant management apparatus using the RAM 92. Specifically, the program 98 includes, for example, a program that causes a computer to execute the processes shown in FIGS. 2 , 8 , 9 , 10 , 11 , and 20 . The processor 91 executes the program 98 to realize the functions of the components of the plant management apparatus. The program 98 may be stored in the ROM 93. Alternatively, the program 98 may be recorded in the storage medium 80 and read out using the drive device 97, or may be transmitted to the computer apparatus 90 from an external device (not shown) via a network (not shown).

[0156] The input / output interface 95 exchanges data with peripheral devices (such as a keyboard, a mouse, and a display device) 99. The input / output interface 95 functions as a means for acquiring or outputting data. The bus 96 connects the various components.

[0157] There are various variations in the method for realizing the plant management device. For example, the plant management device can be realized as a dedicated device. Furthermore, the plant management device can be realized based on a combination of multiple devices.

[0158] The scope of each embodiment also includes a processing method in which a program for realizing each component of the function of each embodiment is recorded on a storage medium, the program recorded on the storage medium is read as code, and the program is executed on a computer.
