[0006] Technical issues

[0007] In alarm management systems, various alarms such as emergency alarms, non-emergency alarms, frequent alarms, and first alarms are generated. Therefore, users such as factory operators who monitor alarms are required to quickly identify and implement appropriate measures corresponding to the alarms.

[0008] However, there are no strict rules on how users should handle (or respond to) these alarms, and the system does not provide support for this. For example, unique rules exist at each plant site, such as requiring approval from the plant's management representative before responding to an alarm, confirmation from another plant operator after responding to an alarm, and requiring plant operators to keep records while performing alarm actions.

Note that the embodiment will be described as an example of remote monitoring of factory production using factory equipment, wherein the factory equipment is equipment installed in a factory; however, the embodiment does not limit the equipment and the field of use, and can also be applied to remote monitoring of environmental measurements, such as power monitoring, wind power generation, water supply and drainage monitoring, and river monitoring.

[0031] 1-1. Example of a general configuration for an alarm management system 100

[0032] The alarm management system 100 includes an alarm management device 10, a response operator terminal device 20, a high-level operator terminal device 30, and a shared operator terminal device 40. The alarm management device 10, the response operator terminal device 20, the high-level operator terminal device 30, and the shared operator terminal device 40 are connected in a wired or wireless manner via a given network (not shown), enabling them to communicate with each other. Note that various types of networks, such as the Internet and dedicated lines, can be used as the given network.

[0033] The responding operator terminal device 20 is the terminal device for responding operator O in response to alarms. The higher-level operator terminal device 30 is the terminal device for controlling and monitoring higher-level operator M, who is also the sharing operator C. The sharing operator terminal device 40 is the terminal device for sharing operator C, which shares the status with responding operator O in response to alarms. Figure 1 The alarm management system 100 shown may include multiple alarm management devices 10, multiple response operator terminal devices 20, multiple advanced operator terminal devices 30, or multiple shared operator terminal devices 40.

[0034] 1-2. Examples of general processes performed by the alarm management system 100

[0035] The general processes performed by the alarm management system 100 described above will be described below. Below, as measures implemented by the responding operator O, and operations related to alarms (referred to as "alarm operations" where appropriate), the alarm response process management process and the alarm suspension process management process will be described. The alarm response process management process is performed when "alarm response" is performed to respond to an alarm immediately, and the alarm suspension process management process is performed when "alarm suspension" is performed to pause response for a given time and then respond to the alarm after a given time has elapsed. The following processes can also be performed in a different order. Some processes may be omitted in the following descriptions.

[0036] 1-2-1. Alarm Response Process Screen Management and Handling

[0037] First, alarm management device 10 sends an alarm (see reference). Figure 1 (a-1)). For example, alarm management device 10 sends alarms generated within the plant that indicate process abnormalities to responder terminal device 20. Alarm management device 10 can detect alarms or receive alarms from alarm devices with alarm detection capabilities.

[0038] Secondly, the operator O should select the alarm response action as the alarm action (see reference). Figure 1(a-2)). For example, operator O selects an alarm response action on the alarm summary display screen shown on operator terminal device 20. Operator terminal device 20 sends the selected alarm response action to alarm management device 10.

[0039] Third, the alarm management device 10 generates an alarm response process screen as a process screen (reference). Figure 1 (a-3)). For example, the alarm management device 10 generates an alarm response process screen that presents a flow of steps for performing alarm response operations based on the type of alarm generated, its location, urgency level, etc. Figure 1 In the example of (a-3), a flowchart is generated that presents the steps of "Confirm Response Manual" → "Request Approval" → "Response in Progress".

[0040] Fourth, the alarm management device 10 displays the alarm response screen as a flowchart (see reference). Figure 1 (a-4)). For example, the alarm management device 10 displays a flow chart on the monitor of the operator terminal device 20 used by the operator O. This flow chart, as an alarm response flow chart, presents the steps of "Confirm Response Manual" → "Request Approval" → "Response in Progress". The alarm management device 10 can display the progress of the alarm response operation by showing buttons such as "Confirm Response Manual" in color (see reference). Figure 1 (a-3)).

[0041] Fifth, respond to operator O confirmation in the response manual (refer to...) Figure 1 (a-5)). For example, operator O clicks the "Confirm Response Manual" button on the alarm response process screen displayed on the monitor of operator terminal device 20, and confirms the displayed online manual. Alarm management device 10 displays an online manual on the monitor of operator terminal device 20 that is associated with the type of alarm generated, the location of the alarm, the urgency level, etc.

[0042] Sixth, the alarm management device 10 requests approval for alarm response operations (see reference). Figure 1 (a-6)). For example, operator O clicks the "Approve Request" button on the alarm response process screen displayed on the monitor of operator terminal device 20. Alarm management device 10 also displays an approval request screen on the monitor of advanced operator terminal device 30, showing the type of work content to be performed by operator O in the alarm response operation, the approval request message, and "Approve" or "Reject" buttons. Advanced operator M confirms the approval request screen displayed on the monitor of advanced operator terminal device 30 and selects "Approve" or "Reject" on the approval request screen.

[0043] Seventh, respond to operator O input response content (refer to...) Figure 1 (a-7)). For example, operator O clicks "Response in progress" on the alarm response process screen displayed on the monitor of operator terminal device 20, and inputs the status of the response operation into the displayed text input screen.

[0044] Eighth, respond to input information sent to the operator's terminal device 20 (refer to...) Figure 1 (a-8)). For example, the operator terminal device 20 sends the status of the work content being performed, as input information in response to the operator O, to the alarm management device 10.

[0045] Ninth, the alarm management device 10 shares the status of alarm operation (refer to...). Figure 1 (a-9)). For example, the shared operator C clicks the "Response in Progress" button on the alarm response process screen displayed on the monitor of the shared operator terminal device 40, and confirms the execution status of the alarm response operation performed by the response operator O.

[0046] 1-2-2. Alarm Shelving Process Screen Management and Handling

[0047] First, the alarm management device 10 issues an alarm notification (see reference). Figure 1 (b-1)). For example, alarm management device 10 will send alarms generated within the plant that indicate process abnormalities to responder terminal device 20.

[0048] Secondly, the operator O should select the alarm shelving operation as the alarm operation (see reference). Figure 1 (b-2)). For example, operator O selects the alarm suspension operation on the alarm summary display screen shown on operator terminal device 20. Operator terminal device 20 sends the alarm suspension operation selection to alarm management device 10.

[0049] Third, the alarm management device 10 generates an alarm suspension process screen as a process screen (reference). Figure 1 (b-3)). For example, the alarm management device 10 generates an alarm shelving process screen that presents a flow of steps for performing an alarm shelving operation based on the type of alarm generated, its location, urgency level, etc. Figure 1 In the example of (b-3), a flowchart is generated that presents the steps of “Enter reason or purpose” → “Request approval” → “Put on hold”.

[0050] Fourth, the alarm management device 10 displays the alarm pause screen as a process screen (see reference). Figure 1(b-4)). For example, the alarm management device 10 displays a flow chart on the monitor of the operator terminal device 20 used by the operator O. This flow chart, as an alarm shelving flow chart, presents the steps of "Enter reason or purpose" → "Request approval" → "Shelving". The alarm management device 10 can present the progress of the alarm shelving operation by displaying buttons such as "Enter reason or purpose" in color (see reference). Figure 1 (b-3)).

[0051] Fifth, the operator should input the reason or purpose (see reference). Figure 1 (b-5)). For example, operator O clicks the "Enter Reason or Purpose" button on the alarm response process screen displayed on the monitor of operator terminal device 20, and enters the reason or purpose for selecting the alarm suspension operation into the displayed text input screen.

[0052] Sixth, it should respond to input information sent by the operator's terminal device 20 (refer to...). Figure 1 (b-6)). For example, the operator terminal device 20 sends the reason or purpose for selecting alarm suspension operation to the alarm management device 10 as input information entered by the operator O.

[0053] Seventh, the alarm management device 10 requests approval for alarm suspension operation (see reference). Figure 1 (b-7)). For example, operator O clicks the "Approval Request" button on the alarm shelving process screen displayed on the monitor of operator terminal device 20. Alarm management device 10 displays an approval request screen on the monitor of advanced operator terminal device 30, showing the reason or purpose for the alarm shelving operation selected by operator O, the message requesting approval, and "Approve" or "Reject" buttons. Advanced operator M confirms the approval request screen displayed on the monitor of advanced operator terminal device 30 and selects "Approve" or "Reject" on the approval request screen.

[0054] Eighth, the alarm management device 10 shares the status of alarm operation (refer to...). Figure 1 (b-8)). For example, on the alarm shelving process screen displayed on the monitor of the shared operator terminal device 40, the shared operator C clicks the "Enter Reason or Purpose" button and confirms the reason or purpose for selecting the alarm shelving operation entered by the responding operator O. The shared operator C can confirm that "Shelving" is displayed on the alarm shelving process screen displayed on the monitor of the shared operator terminal device 40 and recognize that the responding operator O has not yet started the alarm response operation.

[0055] 1-3. The effectiveness of the alarm management system 100

[0056] The background of the alarm management system 100P according to the reference technology, the required functions of the alarm management system 100P, and the overview and problems in the alarm management system 100P will be described below. Then, the effect of the alarm management system 100 will be described below.

[0057] 1-3-1. Background of Alarm Management System 100P

[0058] Alarm Management System 100P is rigorously standardized according to international standards such as ISA 18.2 and IEC 62682 because it features the ability to quickly detect risks on the factory floor, protect company assets, and safeguard the lives of workers operating on the factory floor. According to these standards, the basic alarm functions that Alarm Management System 100P must meet are defined as required and recommended functions, and each control system supplier is required to implement Alarm Management System 100P according to these industry standards.

[0059] In the alarm management system 100P, various alarms such as emergency alarms, non-emergency alarms, frequent alarms, and first alarms are generated. Therefore, the operators who monitor the alarms need to quickly determine the appropriate measures corresponding to the alarms and implement these measures.

[0060] While the functioning of alarms is standardized, there are no strict rules regarding how operators such as O should respond to alarms, and the current alarm management system 100P does not provide support for this. Unique rules are typically set at each plant site. For example, unique rules exist such as requiring approval from a higher-level operator M (as a superior) before responding to an alarm, confirmation from a shared operator C (as another operator) after responding to an alarm, and maintaining a record by the responding operator O when performing an alarm action. The specific implementation of these unique rules is often achieved through low-tech methods independent of the control system or by another system.

[0061] Therefore, in the alarm management system 100P, it is necessary to control the alarm functions included in the system, and these alarm functions should enable the assistance of alarm operations performed by users such as operators O without straining the alarm models based on ISA18.2 or IEC62682.

[0062] 1-3-2. Requires the functionality of an alarm management system (100P).

[0063] The required functions of the alarm management system 100P will be described. Firstly, in alarm monitoring, when an alarm is generated, the operator O should minimize leaving the alarm summary screen. This is because, at the factory site, after an alarm is generated, further related alarms may be generated in the following ways, or there may be unstable changes in the alarm status. Therefore, the alarm management system 100P needs to reduce the workload of the operator O by assisting with alarm operations and external communication.

[0064] Secondly, it is important to record the status of the operator's response to the alarm and the reason or purpose of the alarm action, and to share this information with other members in a simple way so as to prevent chaos on the factory floor in advance. Therefore, the alarm management system 100P needs to provide support for sharing the above-mentioned status to share the status associated with the alarm in real time.

[0065] Third, in this era, the number of experienced operators has decreased, while inexperienced operators frequently perform operations and monitoring. Although experienced operators can master work instructions without referring to manuals, in many cases, inexperienced operators must verify the procedures. Therefore, the alarm management system 100P needs to enable experienced operators to verify the response status in a remote environment.

[0066] 1-3-3. Overview of Alarm Management System 100P

[0067] use Figure 2 This section will describe an overview of the alarm management system 100P based on reference technology. Figure 2 This is a schematic diagram illustrating alarm response operations according to the reference technology. The basic configuration of the alarm management system 100P will be described, followed by an overview of the processes performed by the alarm management system 100P and any issues encountered within the alarm management system 100P.

[0068] 1-3-3-1. Basic Configuration of Alarm Management System 100P

[0069] This section describes the basic configuration of the alarm management system 100P. The HMI (Human-Machine Interface) functions, alarm manual, and management representative will be described below.

[0070] HMI Function

[0071] First, the HMI functionality will be described. The HMI has the ability to collect generated alarms and display alarm messages and current alarm status. Operators can receive notifications about alarms and their current status through the HMI.

[0072] The alarm summary screen display function is an HMI function. The alarm summary screen displays a list of alarms to the responding operator O and uses symbols, strings, sounds, etc., to notify the alarms. The responding operator O can perform alarm confirmation operations, shelve operations (alarm shelve function), etc., on the alarm summary screen. The responding operator O can respond to alarms (e.g., valve control) through the HMI.

[0073] Alarm Manual

[0074] Secondly, the alarm manual will be described. An alarm manual is a response manual defined for each alarm. Alarm manuals exist in various media, such as paper media or online manuals accessible on an intranet, depending on the plant site. Alarm manuals differ from plant site to plant, and therefore in many cases are not prepared by the control system supplier, but rather by the user side of the plant.

[0075] Management Representative

[0076] Third, the management representative, such as a superior or senior operator M, will be described. In many plant settings, approval or confirmation from a management representative, such as a superior or senior operator M, is required when implementing a measure in response to an alarm, or after responding to an alarm. In particular, for measures that affect alarm actions, such as alarm suspension procedures, it is not uncommon to not only approve but also maintain records of the purpose and rationale for the alarm suspension procedure.

[0077] 1-3-3-2. Summary of the processes performed by the alarm management system 100P

[0078] use Figure 2 This section will describe an overview of the processes performed by the alarm management system 100P. Within the alarm management system 100P, particularly regarding alarm generation, the operator O should keep the alarm summary screen open and, while performing operational and monitoring tasks, pay attention to whether any alarms requiring immediate attention have been generated. The operator O should view alarms on the alarm summary screen in a categorized manner according to their preference, either by priority or by generation order, to focus on alarms that must be addressed quickly.

[0079] exist Figure 2 In the example, operator O should perform the alarm response as follows. First, operator O should check the alarm summary screen displayed on the monitor of operator terminal device 20 to confirm whether an alarm has been generated (see [link to example]). Figure 2 (1)). Secondly, when an alarm is generated, the operator should confirm the alarm manual (response manual) necessary for responding to the alarm (see [link]). Figure 2 (2)). Third, the responding operator O should request approval from the senior operator M, who acts as the management representative, to respond to the alarm (see [reference]). Figure 2 (3)). Fourth, the senior operator M approves the response to the alarm (see Figure 2 (4)). Fifth, the operator O should use the operator terminal device 20 to respond to alarms (see...). Figure 2 (5)). Sixth, when responding to an alarm, the responding operator O shall report and confirm the result of responding to the alarm.

[0080] In the processing performed by the alarm management system 100P, the operator O sometimes leaves the HMI, i.e., the operator terminal device 20 is activated as needed. In the alarm management system 100P, multiple alarms are sometimes generated simultaneously; therefore, setting priority order, response time, etc., requires more complex steps.

[0081] In the alarm management system 100P, when multiple high-priority alarms occur simultaneously, the function of shelving lower-priority alarms (alarm shelving function) is defined as a basic function according to ISA 18.2 and IEC 62682. Using this alarm shelving function, operator O is instructed to perform an alarm shelving operation to focus on other tasks. Performing the alarm shelving operation on operator O also aims to temporarily hide lower-priority alarms so that focus can be placed on higher-priority alarms. However, because the alarm shelving operation hides alarms, it requires approval from higher-level operator M, or, in many factory settings, rules are established to leave the alarm shelving with a reason and purpose.

[0082] In a specific example, operator O shall perform an alarm suspension operation as follows: First, operator O confirms whether an alarm has been generated from the alarm summary screen displayed on the monitor of operator terminal device 20. Second, if an alarm has been generated, operator O determines to suspend the alarm and determines the duration for which alarm response will be paused. Third, operator O records the reason or purpose for suspending the alarm. Fourth, operator O requests approval from senior operator M, acting as the management representative, to suspend the alarm. Fifth, senior operator M approves the suspension of the alarm. Sixth, operator O performs the alarm suspension operation using operator terminal device 20.

[0083] In the above process performed by the alarm management system 100P, the responder operator O can leave the HMI as needed, i.e., the responder operator terminal device 20.

[0084] In addition to the processes performed by the alarm management system 100P mentioned above, there are many more alarm operations and response scenarios, and the rules and statuses are different in each factory site.

[0085] 1-3-3-3. Problems with Alarm Management System 100P

[0086] This section will describe the problems of the alarm management system 100P. It will then describe, in turn, problems 1 concerning operator O, 2 concerning higher-level operator M, and 3 concerning shared operator C.

[0087] Question 1

[0088] First, we will describe issue 1 regarding responding to operator O. Responding to operator O requires taking their attention away from the HMI to review the response manual and communicate with senior operator M. Therefore, there is a possibility of status changes, such as alarm status changes, and higher-priority alarms being generated while responding to operator O is out of sight, which could potentially lead to dangerous situations.

[0089] Question 2

[0090] Secondly, issue 2 regarding the higher-level operator M will be described. When responding to operator O requesting approval from higher-level operator M, it is necessary to obtain captured images, create memos to specify the type of alarm ID, and report to higher-level operator M to deliver information about the alarm. These tasks related to communication between operator O and higher-level operator M hinder operator O's work and, in some cases, cause delays in response.

[0091] Question 3

[0092] Third, the third issue 3 regarding shared operator C will be described. In some cases, information sharing is delayed; for example, shared operator C may not know the situation of responding operator O and is only verbally notified later. Therefore, in some cases, shared operator C redundantly responds to alarms, or the reasons or purposes for responding are not shared, and the alarms suddenly disappear, leading to confusion.

[0093] 1-3-4. Overview of Alarm Management System 100

[0094] This section will provide an overview of the alarm management system 100. The alarm response process and alarm suspension process will then be described in turn.

[0095] Alarm response process screen management and processing

[0096] The alarm management system 100 performs alarm response process management as follows: First, the alarm management device 10 sends an alarm. Second, the operator O selects an alarm response operation as the alarm operation. Third, the alarm management device 10 generates an alarm response process screen as the process screen. Fourth, the alarm management device 10 displays the alarm response process screen as the process screen. Fifth, the operator O confirms the response manual. Sixth, the alarm management device 10 requests approval for the alarm response operation. Seventh, the operator O inputs the response content. Eighth, the operator's terminal device 20 sends the input information. Ninth, the alarm management device 10 shares the status of the alarm operation.

[0097] Alarm shelving process screen management and processing

[0098] The alarm management system 100 performs the alarm suspension process as follows: First, the alarm management device 10 sends an alarm. Second, it responds to the operator O's selection of alarm suspension as the alarm operation. Third, the alarm management device 10 generates an alarm suspension process screen as the process screen. Fourth, the alarm management device 10 displays the alarm suspension process screen as the process screen. Fifth, it responds to the operator O's input of a reason or purpose. Sixth, it sends input information to the operator's terminal device 20. Seventh, the alarm management device 10 requests approval for the alarm suspension operation. Eighth, the alarm management device 10 shares the status of the alarm operation.

[0099] 1-3-5. The effectiveness of the alarm response system

[0100] The effects of the alarm management system 100 will be described. The effects on operator O (1), higher-level operator M (2), and shared operator C (3) will be described sequentially.

[0101] Effect 1

[0102] First, the effect on operator O will be described. In the alarm management system 100, operations that would otherwise be pre-executed by external systems or other media, such as manual display, approval and confirmation, and input of reasons for postponing operations, can be completed by operator O within the system. Therefore, the time operator O spends away from the HMI can be reduced, and operator O can focus on monitoring alarms. In the alarm management system 100, the system is integrated with the approval and confirmation system, and thus notifies the approver or confirmer of alarm information and alarm status, such as senior operator M, eliminating the task of interpreting the status for operator O.

[0103] The alarm management system 100 uses flowcharts to provide navigation through the operational steps of alarm response, which enables inexperienced operators O to respond smoothly and allows experienced shared operators C to provide support through confirmation in a remote environment.

[0104] Effect 2

[0105] Next, the effect 2 regarding the high-level operator M will be described. In the alarm management system 100, approvers or confirmers such as the high-level operator M are notified by the system (via chat within the system or via external media such as email) and are thus aware of the existence of a request. In the alarm management system 100, the high-level operator M can confirm the content of the notification and perform an approval or confirmation operation via the system, or via email or a webpage. In the alarm management system 100, a memo is attached to the request notification, such as information about the target alarm, the current status of the target alarm, and the reason or purpose for the operation to be performed by the responding operator O, which allows the content of the target request to be identified even without a person responsible for responding.

[0106] Effect 3

[0107] Third, the effect 3 regarding shared operator C will be described. In the alarm management system 100, shared operator C can confirm the status of alarm responses from the process screen. In the alarm management system 100, when someone responds, shared operator C is introduced into a system that implements exclusive logic to prevent shared operator C from responding, thus avoiding redundant responses. In the alarm management system 100, even when the status of an alarm changes due to alarm shelving operations, the status is confirmed via the process screen, and the reason or purpose is shared, which avoids confusion.

[0108] The alarm management system 100 thus reduces the workload of the operator O in monitoring and responding to alarms, and allows the system to focus on monitoring important alarms. In other words, the alarm management system 100 helps implement measures in response to alarms.

[0109] 2. Configuration of each device in the alarm management system 100 and the processes performed by it.

[0110] use Figure 3 , will describe Figure 1 The alarm management device 10 of the alarm management system 100 shown is configured with functional features.

[0200] exist Figure 6 In the example, operator O performs an alarm response as follows. First, operator O checks the alarm summary screen displayed on the monitor of operator terminal device 20 to confirm whether an alarm has been generated. If an alarm has been generated, operator O selects normal response (immediate response) (see...). Figure 6 (1)). Next, operator O should click the "Confirm Response Manual" button on the "Alarm Response Process Screen" displayed on the monitor of operator terminal device 20, and confirm the displayed online manual (refer to...). Figure 6 (2) Third, the operator O should click the "Approval Request" button on the "Alarm Response Process Screen" displayed on the monitor of the operator terminal device 20, and request approval from the senior operator M to respond to the alarm (refer to...). Figure 6 (3) The advanced operator M can select to approve or reject the alarm response on the approval request screen displayed on the monitor of the advanced operator terminal device 30. Fourth, the response operator O clicks the "Response in Progress" button on the "Alarm Response Process Screen" displayed on the monitor of the response operator terminal device 20, and enters the alarm response work content into the operator notes (see reference).

Figure 6 (5)).

[0201] The processes on the alarm response flowchart described above can be designed as alarm procedures for each user. Additionally, actions for a given process (such as "Confirm Response Manual") can be set as necessary based on the type, location, and urgency of the generated alarm. Emergency response methods can also be set without using the alarm response flowchart, based on the type, location, and urgency of the generated alarm.

[0202] 3-3. Specific example of alarm suspension process screen management and processing

[0204] exist Figure 7In the example, the operator O is instructed to perform an alarm shelving operation as follows: First, operator O checks the alarm summary screen displayed on the monitor of the operator terminal device 20 to confirm whether an alarm has been generated. If an alarm has been generated, operator O selects to shelving (see...). Figure 7 (1)). Next, the operator O should click the "Enter Reason or Purpose" button on the "Alarm Shelving Process Screen" displayed on the monitor of the operator terminal device 20, and enter the reason or purpose for suspending the alarm into the operator comments (refer to...). Figure 7 (2) Third, the responding operator O clicks the "Approval Request" button on the "Alarm Shelving Process Screen" displayed on the monitor of the responding operator terminal device 20, and requests the senior operator M to approve the response to the alarm (see...). Figure 7 (3) The senior operator M can select to approve or reject the postponement on the approval request screen displayed on the monitor of the senior operator terminal device 30. Fourth, by clicking the "Enter Reason or Purpose" button on the "Alarm Response Process Screen" displayed on the monitor of the shared operator terminal device 40, the shared operator C can confirm the reason or purpose of the postponement entered by the response operator O (see reference). Figure 7 (4)).

[0205] The process on the alarm suspension screen described above can be designed as an alarm project for each user. Additionally, based on the type of alarm generated, its location, and urgency level, the operation for a given process (e.g., "Enter reason or purpose") can be set as a necessary action. Emergency response methods can also be set without going through the alarm suspension screen, based on the type of alarm generated, its location, and urgency level.
