Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in an alarm management system, various alarms such as urgent alarms, non-urgent alarms, frequently occurring alarms, and first-occurrence alarms occur. Therefore, users such as plant operators who monitor alarms are required to immediately judge and implement appropriate countermeasures according to the alarms.

[0005] However, there are no strict rules regarding how the above users should respond to the alarms, and the system does not provide support for this. For example, at plant sites, there are unique rules such as the need for approval from the plant manager before responding to an alarm, the need for confirmation from another plant operator after responding to an alarm, and the need for the plant operator to keep a record when an alarm is triggered.

[0006] This invention has been made in view of the above, and aims to support the implementation of countermeasures against alarms. [Means for solving the problem]

[0007] The present invention provides an alarm management device comprising: a storage unit that stores operational procedures for each countermeasure that can be implemented in response to an alarm of a monitored device; a transmission unit that transmits the alarm of the monitored device; a reception unit that receives the countermeasure for the alarm selected by the user; and an output unit that retrieves the operational procedure associated with the countermeasure selected by the user from the storage unit and outputs it to the user.

[0008] Furthermore, the present invention provides an alarm management method in which a computer maintains operational procedures for each countermeasure that can be taken in response to an alarm of a monitored device, transmits the alarm of the monitored device, accepts the countermeasure for the alarm selected by the user, obtains the operational procedures associated with the countermeasure selected by the user, and outputs them to the user.

[0009] Furthermore, the present invention provides an alarm management program that causes a computer to store operational procedures for each countermeasure that can be taken in response to an alarm of a monitored device, transmit the alarm of the monitored device, receive the countermeasure selected by the user for the alarm, obtain the operational procedure associated with the countermeasure selected by the user, and output it to the user. [Effects of the Invention]

[0010] According to the present invention, there is an effect that it can support the implementation of countermeasures against alarms. [Brief explanation of the drawing]

[Figure 10] This is a diagram illustrating an example of a hardware configuration according to the embodiment. [Modes for carrying out the invention]

[0012] An alarm management device, an alarm management method, and an alarm management program according to one embodiment of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the embodiments described below.

[0013] [Embodiment] Below, the configuration and processing of the alarm management system 100 according to the embodiment, the configuration and processing of each device of the alarm management system 100, specific examples of each process of the alarm management system 100, and the flow of the processes of the alarm management system 100 will be described in order, and finally the effects of the embodiment will be described.

[0014] [1. Configuration and Processing of Alarm Management System 100] Using FIG. 1, the configuration and processing of the alarm management system 100 according to the embodiment will be described in detail. FIG. 1 is a diagram showing a configuration example and a processing example of the alarm management system 100 according to the embodiment. Below, a configuration example of the entire alarm management system 100, a processing example of the alarm management system 100, and problems of the alarm management system 100P according to the related art will be described in order, and finally the effects of the alarm management system 100 will be described. In the embodiment, factory production remote monitoring using plant equipment, which is a device installed in a plant, will be described as an example, but the device and the field of use are not limited, and it can also be applied to environmental measurement remote monitoring such as power monitoring, wind power generation, water and sewage monitoring, and river monitoring.

[0015] (1-1. Configuration Example of the Entire Alarm Management System 100) The alarm management system 100 includes an alarm management device 10, a corresponding operator terminal 20, a superior operator terminal 30, and a shared operator terminal 40. Here, the alarm management device 10, the corresponding operator terminal 20, the superior operator terminal 30, and the shared operator terminal 40 are communicably connected by wire or wirelessly via a predetermined communication network (network) not shown. Note that various communication networks such as the Internet and dedicated lines can be adopted for the predetermined communication network.

[0016] Here, the corresponding operator terminal 20 is a terminal used by the corresponding operator O who responds to the alarm. Also, the upper operator terminal 30 is a terminal used by the upper operator M who commands and supervises the corresponding operator O and the shared operator C. Further, the shared operator terminal 40 is a terminal used by the shared operator C who shares the situation with the corresponding operator O who responds to the alarm. Note that the alarm management system 100 shown in FIG. 1 may include a plurality of alarm management devices 10, a plurality of corresponding operator terminals 20, a plurality of upper operator terminals 30, or a plurality of shared operator terminals 40.

[0017] (1-2. Processing example of the entire alarm management system 100) The processing of the entire alarm management system 100 as described above will be explained. Hereinafter, as countermeasures implemented by the corresponding operator O and operations on the alarm (appropriately, "alarm operation"), the alarm response flow screen management process executed when implementing "alarm response" that immediately responds to the alarm, and the alarm shelving flow screen management process executed when implementing "alarm shelving" that defers the response for a certain period and responds to the alarm after a certain period of time will be explained. Note that the following processes can also be executed in a different order. Also, some of the following processes may be omitted.

[0018] (1-2-1. Alarm response flow screen management process) First, the alarm management device 10 transmits an alarm (see FIG. 1(a-1)). For example, the alarm management device 10 transmits an alarm indicating an abnormality in the process occurring in the plant to the corresponding operator terminal 20. At this time, the alarm management device 10 may detect the alarm or receive the alarm from an alarm device having an alarm detection function.

[0019] Secondly, the responding operator O selects an alarm response operation as the alarm operation (see Figure 1(a-2)). For example, the responding operator O selects the alarm response operation on the alarm summary display screen shown on the responding operator terminal 20. The responding operator terminal 20 then transmits the selection of the alarm response operation to the alarm management device 10.

[0020] Thirdly, the alarm management device 10 generates an alarm response flow screen as a flow screen (see Figure 1(a-3)). For example, based on the type of alarm that occurred, the location of the alarm, the urgency, etc., the alarm management device 10 generates an alarm response flow screen that shows the procedure for performing an alarm response operation. In the example in Figure 1(a-3), the alarm response flow screen generates a flow screen that shows the procedure of "Check response manual" → "Request approval" → "Response work in progress".

[0021] Fourth, the alarm management device 10 displays an alarm response flow screen as a flow screen (see Figure 1(a-4)). For example, the alarm management device 10 displays a flow screen showing the procedure of "Check response manual" → "Request approval" → "Response work in progress" on the monitor of the response operator terminal 20 used by the response operator O. At this time, the alarm management device 10 may indicate the progress of the alarm response operation by coloring buttons such as "Check response manual" (see the shaded area in Figure 1(a-3)).

[0022] Fifth, the responding operator O checks the response manual (see Figure 1(a-5)). For example, responding operator O clicks the "Check Response Manual" button on the alarm response flow screen displayed on the monitor of the responding operator terminal 20 and checks the displayed online manual. At this time, the alarm management device 10 displays the online manual linked to the type of alarm that occurred, the location of the alarm, the urgency, etc., on the monitor of the responding operator terminal 20.

[0023] Sixth, the alarm management device 10 requests approval for the alarm response operation (see Figure 1(a-6)). For example, the responding operator O clicks the "Approval Request" button on the alarm response flow screen displayed on the monitor of the responding operator terminal 20. The alarm management device 10 also displays the approval request screen on the monitor of the higher-level operator terminal 30, including the type of work to be performed in the alarm response operation that responding operator O intends to carry out, the message requesting approval, and "Approve" or "Reject" buttons. The higher-level operator M then checks the approval request screen displayed on the monitor of the higher-level operator terminal 30 and selects "Approve" or "Reject" on the approval request screen.

[0024] Seventh, the responding operator O inputs the details of the response (see Figure 1(a-7)). For example, responding operator O clicks "Response in progress" on the alarm response flow screen displayed on the monitor of the responding operator terminal 20, and inputs the status of the response work into the displayed text input screen.

[0025] Eighth, the operator terminal 20 transmits input information (see Figure 1(a-8)). For example, the operator terminal 20 transmits the status of the work performed to the alarm management device 10 as input information entered by the operator O.

[0026] Ninth, the alarm management device 10 shares the status of alarm operations (see Figure 1(a-9)). For example, shared operator C clicks the "In Progress" button on the alarm response flow screen displayed on the monitor of the shared operator terminal 40 to check the status of the alarm response operation performed by the displayed response operator O.

[0027] (1-2-2. Alarm Shelf Management Flow Screen Processing) Firstly, the alarm management device 10 notifies of an alarm (see Figure 1(b-1)). For example, the alarm management device 10 transmits an alarm indicating a process abnormality that has occurred in the plant to the corresponding operator terminal 20.

[0028] Secondly, the responding operator O selects the alarm deactivation operation as the alarm operation (see Figure 1(b-2)). For example, the responding operator O selects the alarm deactivation operation on the alarm summary display screen shown on the responding operator terminal 20. The responding operator terminal 20 then transmits the selection of the alarm deactivation operation to the alarm management device 10.

[0029] Thirdly, the alarm management device 10 generates an alarm shelving flow screen as a flow screen (see Figure 1(b-3)). For example, based on the type of alarm that occurred, the location of the alarm, the urgency, etc., the alarm management device 10 generates an alarm shelving flow screen that shows the procedure for performing the alarm shelving operation. In the example in Figure 1(b-3), the alarm shelving flow screen generates a flow screen that shows the procedure of "Enter reason / purpose" → "Request approval" → "Shelving in progress".

[0030] Fourth, the alarm management device 10 displays an alarm shelving flow screen as a flow screen (see Figure 1(b-4)). For example, the alarm management device 10 displays a flow screen showing the procedure of "Enter Reason / Purpose" → "Request Approval" → "Shelving" on the monitor of the operator terminal 20 used by the operator O as the alarm shelving flow screen. At this time, the alarm management device 10 may indicate the progress of the alarm shelving operation by coloring buttons such as "Enter Reason / Purpose" (see the shaded area in Figure 1(b-3)).

[0031] Fifth, the responding operator O enters the reason or purpose (see Figure 1(b-5)). For example, responding operator O clicks the "Enter Reason / Purpose" button on the alarm response flow screen displayed on the monitor of the responding operator terminal 20, and enters the reason or purpose for selecting the alarm shelving operation in the displayed text input screen.

[0032] Sixth, the operator terminal 20 transmits input information (see Figure 1(b-6)). For example, the operator terminal 20 transmits to the alarm management device 10 the reason or purpose for selecting the alarm shelving operation as input information entered by the operator O.

[0033] Seventh, the alarm management device 10 requests approval for the alarm deactivation operation (see Figure 1(b-7)). For example, the responding operator O clicks the "Approval Request" button on the alarm deactivation flow screen displayed on the monitor of the responding operator terminal 20. The alarm management device 10 also displays the approval request screen on the monitor of the higher-level operator terminal 30, including the reason or purpose for selecting the alarm deactivation operation entered by the responding operator O, a message requesting approval, and "Approve" or "Reject" buttons. The higher-level operator M then checks the approval request screen displayed on the monitor of the higher-level operator terminal 30 and selects "Approve" or "Reject" on the approval request screen.

[0034] Eighth, the alarm management device 10 shares the status of alarm operations (see Figure 1(b-8)). For example, shared operator C clicks the "Enter Reason / Purpose" button on the alarm shelving flow screen displayed on the monitor of the shared operator terminal 40 to confirm the reason or purpose for selecting the alarm shelving operation entered by the responding operator O. Shared operator C can also confirm that "Shelving in Progress" is displayed on the alarm shelving flow screen on the monitor of the shared operator terminal 40, and recognize that the responding operator O has not yet started an alarm response operation.

[0035] (1-3. Effects of the Alarm Management System 100) The following sections will explain the background of the alarm management system 100P related to the reference technology, the functions required for the alarm management system 100P, an overview of the alarm management system 100P, and its problems, and then describe the effects of the alarm management system 100.

[0036] (1-3-1. Background of the Alarm Management System 100P) The Alarm Management System 100P, due to its function of promptly detecting hazards at plant sites, protecting corporate assets, and safeguarding the lives of workers on site, is strictly standardized by international standards such as ISA18.2 and IEC62682. These standards define the basic alarm functions that the Alarm Management System 100P must meet as essential and recommended functions, and it has become industry-wide requirement for each control system vendor to implement the Alarm Management System 100P in accordance with these standards.

[0037] By the way, the alarm management system 100P generates various types of alarms, including urgent alarms, non-urgent alarms, frequently occurring alarms, and first-time alarms. Therefore, the response operators O who monitor the alarms are required to immediately determine and implement appropriate countermeasures according to the alarm.

[0038] However, while the functionality of alarms is becoming standardized, there are currently no strict rules regarding how responding operators O, who monitor alarms, should respond to them, and this is not supported by the alarm management system 100P. Furthermore, unique rules are often established at plant sites. For example, there are unique rules such as requiring approval from a superior operator M before responding to an alarm, requiring confirmation from another operator, such as a shared operator C, after responding to an alarm, or requiring responding operator O to keep a record when an alarm is activated. In such cases, the specific means of complying with these unique rules are often low-tech methods that do not rely on the control system, or are handled by separate systems.

[0039] Therefore, the alarm management system 100P requires an alarm function that can assist users, such as the corresponding operator O, in operating alarms without deviating from the alarm model based on ISA18.2 or IEC62682.

[0040] (1-3-2. Functions required for the Alarm Management System 100P) This section describes the functions required for the alarm management system 100P. Firstly, the responding operator O should avoid leaving the alarm summary screen as much as possible while an alarm is occurring during alarm monitoring. This is because, in a plant environment, related alarms may occur after an initial alarm, or the alarm state may transition without being stable. Therefore, the alarm management system 100P needs to reduce the burden on the responding operator O by supporting alarm operation and external communication.

[0041] Secondly, it is important to record the alarm response status of operator O, as well as the reasons and purposes for the alarm operation. By sharing this information with other members in a simple manner, confusion at the plant site can be prevented. Therefore, the alarm management system 100P needs to support the sharing of the above situation, and to share the situation in real time in conjunction with the alarm status.

[0042] Thirdly, given the current circumstances, the number of skilled operators is decreasing, and in many cases, less experienced operators are performing operations and monitoring. While skilled operators can understand the work sequence without referring to the response manual, less experienced operators often need to confirm the procedure. Therefore, the alarm management system 100P needs a mechanism that allows skilled operators to check the response status from a remote environment.

[0043] (1-3-3. Overview of the Alarm Management System 100P) Using Figure 2, we will explain the overview of the alarm management system 100P related to the reference technology. Figure 2 is a diagram illustrating the alarm response operation related to the reference technology. Below, we will explain the basic configuration of the alarm management system 100P, followed by an overview of the processing of the alarm management system 100P and its problems.

[0044] (1-3-3-1. Basic configuration of the Alarm Management System 100P) This section explains the basic configuration of the Alarm Management System 100P. The following sections will cover the HMI (Human Machine Interface) function, alarm manual, and the responsible administrator.

[0045] (HMI function) First, let's explain the HMI function. The HMI has the function of collecting alarms generated by the alarm management function and displaying alarm messages and the current alarm status. The operator O can receive alarm notifications and learn about the current alarm status through the HMI.

[0046] Furthermore, the alarm summary screen display function is one of the HMI functions. The alarm summary screen displays a list of alarms to the operator O and notifies the operator of the alarms using marks, text, sounds, etc. The operator O can also perform alarm confirmation operations, shelving operations (alarm shelving function), etc. from the alarm summary screen. In addition, the operator O can also take action against alarms (valve control, etc.) through the HMI.

[0047] (Alarm Manual) Secondly, I will explain the alarm manual. An alarm manual is a response manual defined for each type of alarm. Depending on the plant site, the medium of the alarm manual may vary, such as being in paper format or an online manual published on the intranet. Also, since alarm manuals differ from plant site to plant, they are often prepared by the users of the plant rather than the control system vendor.

[0048] (Administrator) Thirdly, I will explain the role of supervisors and senior operators such as M. In many plant sites, approval or confirmation from supervisors and senior operators is required when implementing any measures in response to an alarm, or after responding to an alarm. In particular, for measures that affect the behavior of an alarm, such as alarm suppression operations, it is often required not only to approve the action but also to record the purpose and reasons for suppressing the alarm.

[0049] (1-3-3-2. Overview of the processing of the alarm management system 100P) Figure 2 illustrates the overview of the alarm management system 100P's processing. In the alarm management system 100P, the responding operator O performs operations and monitoring while constantly checking the alarm summary screen to see if any alarms requiring attention have occurred. At this time, the responding operator O sorts and displays alarms on the alarm summary screen according to their preferences, such as priority order or occurrence order, so that they can focus on those that require immediate attention. Therefore, the responding operator O tries to avoid displaying alarms that do not require attention or do not require immediate attention as much as possible.

[0050] In the example in Figure 2, operator O performs the alarm response operation as follows: First, operator O checks whether an alarm has occurred from the alarm summary screen displayed on the monitor of operator terminal 20 (see Figure 2(1)). Second, if an alarm has occurred, operator O checks the alarm manual (response manual) necessary for alarm response (see Figure 2(2)). Third, operator O requests approval for alarm response from senior operator M, who is the manager in charge, as necessary (see Figure 2(3)). Fourth, senior operator M approves the alarm response (see Figure 2(4)). Fifth, operator O performs the alarm response using operator terminal 20 (see Figure 2(5)). Sixth, if operator O has performed the alarm response, operator O reports and confirms the results of the alarm response.

[0051] In the processing of the alarm management system 100P described above, the responding operator O may leave the HMI, i.e., the responding operator terminal 20, as needed. Furthermore, since multiple alarms may occur simultaneously in the alarm management system 100P, if priority orders or required response times are set, even more complex procedures will be required.

[0052] Furthermore, in the alarm management system 100P, a function to temporarily shelve lower-priority alarms when higher-priority alarms are issued simultaneously (alarm shelving function) is defined as a mandatory function in ISA18.2 and IEC62682. Operator O uses the above alarm shelving function to perform the alarm shelving operation in order to concentrate on other tasks. Operator O also performs the alarm shelving operation with the intention of temporarily hiding lower-priority alarms in order to concentrate on responding to higher-priority alarms. However, due to the nature of the alarm shelving operation, which involves hiding alarms, many plant sites require approval from a higher-ranking operator M or have rules in place to record the reasons and purposes for doing so.

[0053] In a specific example, operator O performs the alarm deferral operation as follows: First, operator O checks whether an alarm has occurred from the alarm summary screen displayed on the monitor of operator terminal 20. Second, if an alarm has occurred, operator O decides to perform the alarm deferral operation and determines the deferral period during which the alarm response will be postponed. Third, operator O records the reason and purpose for performing the alarm deferral operation. Fourth, operator O requests approval for alarm deferral from senior operator M, who is the manager in charge, as necessary. Fourth, senior operator M approves the alarm deferral. Fifth, operator O performs the alarm deferral operation using operator terminal 20.

[0054] In the processing of the alarm management system 100P described above, the responding operator O may leave the HMI, i.e., the responding operator terminal 20, as necessary.

[0055] In addition to the processing performed by the alarm management system 100P described above, there are many other alarm operations and response cases, and the rules and circumstances differ from plant site to plant.

[0056] (1-3-3-3. Problems with the Alarm Management System 100P) This document explains the problems with the alarm management system 100P. The problems will be described in the following order: Problem 1 related to responding operator O, Problem 2 related to senior operator M, and Problem 3 related to shared operator C.

[0057] (Problem 1) First, let's discuss problem 1 related to response operator O. Response operator O needs to take their eyes off the HMI to check the response manual and communicate with senior operator M. Therefore, while response operator O is away, the situation may change, such as the alarm status changing or a higher-priority alarm occurring, which could lead to a dangerous situation.

[0058] (Problem 2) Secondly, I will explain problem 2 related to senior operator M. When responding operator O requests approval from senior operator M, etc., it is necessary to obtain captured images, make notes such as IDs to identify the alarm type, etc., in order to convey alarm information, etc., and report this to senior operator M, etc. The effort required for responding operator O to communicate with senior operator M, etc. as described above can hinder responding operator O's work and may cause delays in response.

[0059] (Problem 3) Thirdly, I will explain problem 3 related to shared operator C. Shared operator C may not be aware of the status of responding operator O, and there are cases where information sharing is delayed, such as learning about it later verbally. As a result, shared operator C may end up responding to alarms twice, or the reasons and objectives for responding may not be shared, causing alarms to suddenly disappear and leading to confusion.

[0060] (1-3-4. Overview of Alarm Management System 100) This section provides an overview of the alarm management system 100. The following sections will describe the alarm response flow screen management process, followed by the alarm shelving flow screen management process.

[0061] (Alarm response flow screen management processing) The alarm management system 100 performs the following alarm response flow screen management process: First, the alarm management device 10 sends an alarm. Second, the responding operator O selects an alarm response operation as the alarm operation. Third, the alarm management device 10 generates an alarm response flow screen as a flow screen. Fourth, the alarm management device 10 displays the alarm response flow screen as a flow screen. Fifth, the responding operator O checks the response manual. Sixth, the alarm management device 10 requests approval for the alarm response operation. Seventh, the responding operator O inputs the response details. Eighth, the responding operator terminal 20 transmits the input information. Ninth, the alarm management device 10 shares the status of the alarm operation.

[0062] (Alarm Shelving Flow Screen Management Process) The alarm management system 100 executes the alarm shelving flow screen management process as follows: First, the alarm management device 10 sends an alarm. Second, the responding operator O selects the alarm shelving operation as the alarm operation. Third, the alarm management device 10 generates the alarm shelving flow screen as the flow screen. Fourth, the alarm management device 10 displays the alarm shelving flow screen as the flow screen. Fifth, the responding operator O enters the reason or purpose. Sixth, the responding operator terminal 20 sends the input information. Seventh, the alarm management device 10 requests approval for the alarm shelving operation. Eighth, the alarm management device 10 shares the status of the alarm operation.

[0063] (1-3-5. The effectiveness of the alarm management system 100) The effects of the alarm management system 100 will be explained in the following order: Effect 1 related to the responding operator O, Effect 2 related to the senior operator M, and Effect 3 related to the shared operator C.

[0064] (Effect 1) First, let's explain the effect related to the responding operator O. With the alarm management system 100, responding operator O can complete tasks that previously relied on external systems or other media, such as manual display, approval and confirmation, and inputting reasons for shelving operations, all within the system. This reduces the time O spends away from the HMI, allowing them to concentrate on alarm monitoring. Furthermore, the alarm management system 100 integrates approval and confirmation mechanisms, automatically notifying approvers and verifiers, such as senior operators M, of the relevant alarm information and status, thus saving responding operator O the trouble of explaining the situation.

[0065] Furthermore, the alarm management system 100 provides a flowchart to guide users through the alarm response procedure, allowing even inexperienced operators O to respond smoothly. Additionally, other experienced co-operators C can remotely monitor the situation and provide support.

[0066] (Effect 2) Secondly, we will explain Effect 2 related to Senior Operator M. In the alarm management system 100, approvers and verifiers such as Senior Operator M can become aware of requests through notifications from the system (internal chat, email, or other external media). In addition, in the alarm management system 100, Senior Operator M can check the content of the notification and perform approval or confirmation operations through the system, or perform operations via email or web page. Furthermore, in the alarm management system 100, the request notification is accompanied by notes such as information about the target alarm, its current status, and the reason and purpose of the operation by the responding operator O, so that the content of the request can be understood even if the responding person is not present.

[0067] (Effect 3) Thirdly, we will explain effect 3 related to shared operator C. In the alarm management system 100, shared operator C can check the status of alarm responses from the flow screen. At this time, the alarm management system 100 introduces a mechanism that applies exclusive logic so that if someone has started responding, shared operator C cannot take action, thus eliminating redundant responses. In addition, in the alarm management system 100, even if the status of an alarm changes due to an alarm shelving operation or the like, the situation can be checked via the flow screen, the reason and purpose can be shared, and confusion can be avoided.

[0068] Based on the above, the alarm management system 100 reduces the burden on the response operator O who monitors alarms, enabling system support to allow them to concentrate on monitoring important alarms. In other words, the alarm management system 100 can support the implementation of countermeasures against alarms.

[0069] [2. Configuration and Processing of Each Device in the Alarm Management System 100] Using Figure 3, the configuration and processing of the alarm management device 10 of the alarm management system 100 shown in Figure 1 will be explained. Figure 3 is a block diagram showing an example of the configuration of each device of the alarm management system 100 according to the embodiment. Below, an example of the overall configuration of the alarm management system 100 according to the embodiment will be explained, followed by a detailed explanation of the configuration and processing examples of the alarm management device 10, the corresponding operator terminal 20, the higher-level operator terminal 30, and the shared operator terminal 40.

[0070] (2-1. Example of the overall configuration of the alarm management system 100) Using Figure 3, an example of the overall configuration of the alarm management system 100 shown in Figure 1 will be explained. As shown in Figure 3, the alarm management system 100 includes an alarm management device 10, a corresponding operator terminal 20, a higher-level operator terminal 30, and a shared operator terminal 40. The alarm management device 10 is connected to the corresponding operator terminal 20, the higher-level operator terminal 30, and the shared operator terminal 40 via a communication network N, which is implemented via the internet or a dedicated line.

[0071] (2-2. Example of configuration and processing of alarm management device 10) Using Figure 3, an example of the configuration and processing of the alarm management device 10 will be explained. The alarm management device 10 includes a communication unit 11, a storage unit 12, and a control unit 13. The alarm management device 10 may also have an input unit (e.g., a keyboard or mouse) for receiving various operations from the administrator of the alarm management device 10, and a display unit (e.g., a liquid crystal display) for displaying various information.

[0072] (2-2-1. Communications Section 11) The communication unit 11 is responsible for data communication with other devices. For example, the communication unit 11 communicates data with each communication device via a router or the like. The communication unit 11 can also communicate data with an operator's terminal (not shown).

[0073] (2-2-2. Storage section 12) The storage unit 12 stores various information that the control unit 13 refers to when it operates, and various information acquired when the control unit 13 operates. The storage unit 12 has an alarm-responding flow screen storage unit 12a and an alarm-shelving flow screen storage unit 12b. Here, the storage unit 12 can be implemented as, for example, a semiconductor memory element such as RAM (Random Access Memory) or flash memory, or a storage device such as a hard disk or optical disc. In the example in Figure 3, the storage unit 12 is installed inside the alarm management device 10, but it may be installed outside the alarm management device 10, or multiple storage units may be installed.

[0074] The memory unit 12 stores operational procedures for each possible countermeasure in response to an alarm of the monitored equipment. For example, the memory unit 12 stores operational procedures including an immediate response flow screen (alarm response flow screen) that shows the operational procedures for immediate response operations in response to an alarm. The memory unit 12 also stores operational procedures including a postponement flow screen (alarm postponement flow screen) that shows the operational procedures for postponement operations in response to an alarm, where the response is postponed for a certain period of time and an action is taken after that period has elapsed.

When shared operator C clicks a button such as "Handling in Progress" on the alarm response flow screen, a dialog box is displayed that describes the work performed by responding operator O in response to the alarm, along with a message such as "Displaying completed work details." At this time, the output unit 13c can also display the button indicating the currently performed operation procedure (e.g., "Check Response Manual") in a different color (e.g., red) to indicate the progress.

[0097] To give a specific example of the alarm shelving flow screen, the output unit 13c displays the alarm shelving flow screen for the alarm being shelved by operator O on the monitor of the shared operator terminal 40 used by shared operator C. When shared operator C clicks a button such as "Enter Reason / Purpose" on the alarm shelving flow screen, a dialog box is displayed with a message such as "We will display the reason / purpose for shelving," along with a message stating the reason or purpose for which the user selected the shelving operation for the alarm. At this time, the output unit 13c can also display the button indicating the currently performed operation procedure (e.g., "Enter Reason / Purpose") in a different color (e.g., red) to indicate the progress.

[0098] (Process to display the approval request screen) The output unit 13c executes the approval request screen display process. Specifically, in the immediate response flow screen, the output unit 13c displays a screen on the administrator terminal of the administrator managing the monitored equipment where the alarm occurred, allowing the user to request approval for the work to be performed in response to the alarm. In addition, in the shelving flow screen, the output unit 13c displays a screen on the administrator terminal of the administrator managing the monitored equipment where the alarm occurred, allowing the user to request approval for a shelving operation in response to the alarm.

[0099] To give a specific example of the alarm response flow screen, if the reception unit 13b has received a request for an immediate response operation as a possible countermeasure, the output unit 13c displays a window on the monitor of the senior operator terminal 30 used by the senior operator M, along with a message such as "We will implement the XXXXXX response. Please approve." and buttons such as "Approve" and "Reject".

[0100] To give a specific example of the alarm deferral flow screen, if the output unit 13c has received a deferral operation as a possible measure that can be implemented by the reception unit 13b, it displays a window on the monitor of the upper-level operator terminal 30 used by the upper-level operator M with a message such as "Deferring for 24 hours to address XXXXX," along with buttons such as "Approve" and "Reject."

[0119] [3. Specific examples of each process in the alarm management system 100] Using Figures 6 and 7, specific examples of each process of the alarm management system 100 according to the embodiment will be described. Below, the basic configuration of the alarm management system 100 according to the embodiment will be described, followed by specific examples of alarm response flow screen management processing, alarm shelving flow screen management processing, and application examples of the alarm management system 100.

[0120] (3-1. Basic Configuration of Alarm Management System 100) In the following, the basic configuration of the alarm management system 100 according to this embodiment will be described in the order of the flow screen and the operator note function.

[0121] (3-1-1. Flow Screen) First, a flow screen according to the embodiment will be described. For each alarm operation (alarm confirmation, shelving, inventory, etc.), the corresponding flow is displayed as a flowchart. The flow screen can be displayed from the alarm summary screen or the like with simple operations such as clicking or double-clicking.

[0122] The flow screen displays the current process status at a glance (e.g., the corresponding flow is color-coded), and includes features such as displaying online manuals and approval request screens for senior operators M, allowing tasks to be completed within the system. Approval requests to senior operators M can be made using in-system notifications or email notifications.

[0123] Furthermore, the flow screen allows for the sharing of operator notes (described later) with the corresponding operator O, senior operator M, shared operator C, etc., within each process of the flow.

[0124] (3-1-2. Operator Note Function) Secondly, the operator note function according to the embodiment will be described. The operator note function is a function that allows the responding operator O to share operation notes with other operators and to receive interactive replies. The operator note function also includes approval and confirmation functions, so that by selecting a recipient and sending an approval request, a notification (such as in-system chat or email) is sent to the recipient approver. Approvers such as senior operator M can approve or confirm through the system (or by replying to an email if they are out of the office). In addition, the operator note function allows writing and reading permissions to be set for each user.

[0125] Furthermore, the operator note function works in conjunction with the flow screen, requiring the input of reasons and objectives in the approval and operator notes. This locks the flow, preventing it from progressing until approval is granted or the input of reasons and objectives is completed. In addition, if approval is rejected using the operator note function, the responding operator O can check the reason for rejection, take appropriate action, and resubmit the approval request.

[0126] (3-2. Specific Examples of Alarm Response Flow Screen Management Processes) Using Figure 6, a specific example of the alarm response flow screen management process executed by the alarm management system 100 will be explained. Figure 6 is a diagram showing a specific example of the alarm response flow screen management process according to the embodiment.

[0127] In the example shown in Figure 6, the responding operator O performs the alarm response operation as follows: First, responding operator O checks whether an alarm has occurred from the alarm summary screen displayed on the monitor of the responding operator terminal 20, and if an alarm has occurred, selects normal response (immediate response) (see Figure 6(1)). Second, responding operator O clicks the "Check Response Manual" button on the "Alarm Response Flow Screen" displayed on the monitor of the responding operator terminal 20 and checks the displayed online manual (see Figure 6(2)). Third, responding operator O clicks the "Request Approval" button on the "Alarm Response Flow Screen" displayed on the monitor of the responding operator terminal 20 and requests approval for the alarm response from the senior operator M (see Figure 6(3)). At this time, the senior operator M can select to approve or reject the alarm response on the approval request screen displayed on the monitor of the senior operator terminal 30. Fourth, responding operator O clicks the "Responding" button on the "Alarm Response Flow Screen" displayed on the monitor of responding operator terminal 20 and enters the details of the alarm response work performed into the operator's notebook (see Figure 6(4)). Fifth, shared operator C can check the details of the work performed by responding operator O by clicking the "Responding" button on the "Alarm Response Flow Screen" displayed on the monitor of shared operator terminal 40 (see Figure 6(5)).

[0128] The flow in the alarm response flow screen described above can be designed for each user as part of alarm engineering. Furthermore, based on the type, location, and urgency of the alarm, it is possible to set a required action (e.g., "Check response manual"). It is also possible to set emergency response methods that bypass the alarm response flow screen, based on the type, location, and urgency of the alarm.

[0129] (3-3. Specific example of alarm shelving flow screen management process) Using Figure 7, a specific example of the alarm shelving flow screen management process executed by the alarm management system 100 will be explained. Figure 7 is a diagram showing a specific example of the alarm shelving flow screen management process according to the embodiment.

[0130] In the example shown in Figure 7, the responding operator O performs the alarm shelving operation as follows: First, responding operator O checks whether an alarm has occurred from the alarm summary screen displayed on the monitor of the responding operator terminal 20, and selects shelving if an alarm has occurred (see Figure 7(1)). Second, responding operator O clicks the "Reason / Purpose Input" button on the "Alarm Shelving Flow Screen" displayed on the monitor of the responding operator terminal 20 and enters the reason or purpose for shelving the alarm into the operator's notes (see Figure 7(2)). Third, responding operator O clicks the "Approval Request" button on the "Alarm Shelving Flow Screen" displayed on the monitor of the responding operator terminal 20 and requests approval for alarm handling from the senior operator M (see Figure 7(3)). At this time, the senior operator M can select to approve or reject the shelving on the approval request screen displayed on the monitor of the senior operator terminal 30. Fourth, shared operator C can confirm the reason or purpose for shelving entered by responding operator O by clicking the "Reason / Purpose Input" button on the "Alarm Response Flow Screen" displayed on the monitor of shared operator terminal 40 (see Figure 7(4)).

[0131] The flow in the above alarm deferral flow screen can be designed for each user as part of alarm engineering. Furthermore, based on the type, location, and urgency of the alarm, it is possible to set a required operation for a specific flow (e.g., "Enter Reason / Purpose"). It is also possible to set emergency response methods that bypass the alarm deferral flow screen based on the type, location, and urgency of the alarm.

[0132] (3-4. Application Examples of Alarm Management System 100) In the following sections, we will describe examples of the application of the alarm management system 100 according to the embodiment, starting with educational support and then accumulating know-how.

[0133] (3-4-1. Educational Support) As an example of the application of the alarm management system 100, we will describe its use in supporting training from experienced personnel to novice personnel. The alarm management system 100 can be used as a training tool for inexperienced novice personnel by combining it with a function that simulates plant accident situations using the plant control system. Here, since the number of experienced personnel is limited, it is conceivable that they may only be in a remote environment rather than on-site. Even in such cases, the alarm management system 100 can provide comprehensive training support by integrating with the system.

[0134] For example, the alarm management system 100 can reproduce the alarm situation on the day of an accident using a simulator, and experienced operators can provide support in real time through operator notes. In the alarm management system 100P, which is a reference technology, it was difficult to conduct rehearsals outside the system, such as approval procedures, but the alarm management system 100 makes it easy to conduct the above rehearsals within the system. In addition, the alarm management system 100 can promote education through more interactive communication by linking voice call and video chat functions with the flow screen.

[0135] (3-4-2. Accumulation of know-how) As an example of applying the alarm management system 100, we will describe an example of accumulating operator notes as know-how. The alarm management system 100 records the history of responses to alarms, and by accumulating information such as who responded, how, and what problems occurred in the operator notes, it can be compiled into a collection of know-how. This know-how can be utilized in similar jobs and can be used as reference information during operations or as training material.

[0136] Furthermore, by keeping a record of the raw response history of the responding operator O, the alarm management system 100 allows for the consideration of more effective countermeasures when an accident or other incident actually occurs, rather than just relying on error logs.

[0137] [4. Flow of each process in the alarm management system 100] The flow of each process in the alarm management system 100 according to the embodiment will be explained using Figures 8 and 9. Below, the alarm response flow screen management process and the alarm shelving flow screen management process according to the embodiment will be explained in that order.

[0138] (4-1. Alarm response flow screen management processing) Using Figure 8, the flow of the alarm response flow screen management process of the alarm management system 100 according to the embodiment will be explained. Figure 8 is a sequence diagram showing an example of the flow of the alarm response flow screen management process of the alarm management system 100 according to the embodiment. In the following, the alarm response flow screen management process will be explained in the following order: alarm response selection management process, alarm response flow screen management process, response manual management process, work content approval management process, and alarm response status sharing management process. Note that the processes in steps S101 to S117 below can also be executed in a different order. Also, some of the processes in steps S101 to S117 below may be omitted.

[0139] (4-1-1. Alarm response selection management process) The alarm management system 100 executes the alarm response selection management process shown in steps S101 to S105 below.

[0140] First, the alarm management device 10 performs an alarm information creation process (step S101). Second, the alarm management device 10 performs an alarm information transmission process (step S102). Third, the corresponding operator terminal 20 performs an alarm screen display process (step S103).
