[0012] An alarm management apparatus, an alarm management method, and an alarm management program according to an embodiment of the present invention will be described in detail below with reference to the drawings.　Note that the present invention is not limited by the embodiment described below.

[0013] Embodiment A configuration of and a process performed by an alarm management system 100, a configuration of and a process performed by each device of the alarm management system 100, a specific example of each process performed by the alarm management system 100, and a flow of the process performed by the alarm management system 100 will be described in order and an effect of the embodiment will be described lastly.

[0014] 1. Configuration of and Process performed by Alarm Management System 100 Using Fig. 1, the configuration of and the process performed by the alarm management system 100 according to the embodiment will be described in detail.　Fig. 1 is a diagram illustrating an example of the configuration of and am example of the process performed by the alarm management system 100 according to the embodiment.　Problems of the example of the general configuration of the alarm management system 100, the example of the process performed by the alarm management system 100, and an alarm management system 100P of a reference technique will be described in order and an effect of the alarm management system 100 will be described lastly.　Note that the embodiment will be described, taking, as an example, factory production remote monitoring using a plant device that is a device set in a plant; however the embodiment does not limit the device and the field of use and is also applicable to environmental measurement remote monitoring, such as power monitoring, wind power generation, water and sewerage monitoring, and river monitoring.

[0015] 1-1. Example of General Configuration of Alarm Management System 100 The alarm management system 100 includes an alarm management apparatus 10, a handling-operator terminal device 20, a higher-operator terminal device 30, and a sharing-operator terminal device 40.　The alarm management apparatus 10, the handling-operator terminal device 20, the higher-operator terminal device 30, and the sharing-operator terminal device 40 are connected in a wired or a wireless manner via a given network not illustrated in the drawings such that they can communicate with one another.　Note that various types of networks, such as the Internet and a dedicated line, can be employed as the given network.

[0016] The handling-operator terminal device 20 is a terminal device of a handling-operator O who handles alarms.　The higher-operator terminal device 30 is a terminal device of a higher-operator M who controls and supervises the handling-operator O and the sharing-operator C.　The sharing-operator terminal device 40 is a terminal device of the sharing-operator C who shares the status with the handling-operator O who handles alarms.　The alarm management system 100 illustrated in Fig. 1 may include a plurality of the alarm management apparatuses 10, a plurality of the handling-operator terminal devices 20, a plurality of the higher-operator terminal devices 30 or a plurality of the sharing-operator terminal devices 40.

[0017] 1-2. Example of General Process performed by Alarm Management System 100 A general process performed by the alarm management system 100 described above will be described.　An alarm handling flow screen management process that is executed when "alarm handling" of handling an alarm instantly is performed and an alarm shelving flow screen management process that is executed when "alarm shelving" of suspending handling for a given time and handling an alarm after the given time passes is performed will be described below as operations that are measures implemented by the handling-operator O and that are against alarms ("alarm operations" as appropriate).　It is possible to execute the following processes also in a different order.　There may be a process to be omitted among the following processes.

[0018] 1-2-1. Alarm Handling Flow Screen Management Process First of all, the alarm management apparatus 10 transmits an alarm (refer to Fig. 1(a-1)).　For example, the alarm management apparatus 10 transmits an alarm representing an abnormality in a process and generated in a plant to the handling-operator terminal device 20.　The alarm management apparatus 10 may detect the alarm or receive the alarm from an alarm device having an alarm detecting function.

[0019] Secondly, the handling-operator O selects an alarm handling operation as an alarm operation (refer to Fig. 1(a-2)).　For example, the handling-operator O selects the alarm handling operation on an alarm summary display screen that is displayed on the handling-operator terminal device 20.　The handling-operator terminal device 20 transmits the selection of the alarm handling operation to the alarm management apparatus 10.

[0020] Thirdly, the alarm management apparatus 10 generates an alarm handling flow screen as a flow screen (refer to Fig. 1(a-3)).　For example, the alarm management apparatus 10 generates the alarm handling flow screen presenting a flow of a procedure of performing the alarm handling operation based on the type of the generated alarm, the location of generation, the degree of emergency, etc.　In the example in Fig. 1(a-3), a flow screen presenting the flow of the procedure of "check handling manual"→"make request for approval"→"in handling work" is generated.

[0021] Fourthly, the alarm management apparatus 10 displays the alarm handling screen as a flow screen (refer to Fig. 1(a-4)).　For example, the alarm management apparatus 10 displays the flow screen presenting the flow of the procedure of "check handling manual"→"make request for approval"→"in handling work" as the alarm handling flow screen on a monitor of the handling-operator terminal device 20 that the handling-operator O uses.　The alarm management apparatus 10 may present the progress of the alarm handling operation by displaying a button, such as "Check handling manual", in a colored manner (refer to Fig. 1(a-3)).

[0022] Fifthly, the handling-operator O checks a handling manual (refer to Fig. 1(a-5)).　For example, the handling-operator O performs an operation of clicking a "check handling manual" button on the alarm handling flow screen that is displayed on the monitor of the handling-operator terminal device 20 and checks the displayed online manual.　The alarm management apparatus 10 displays the online manual that is associated with the type of the generated alarm, the location of generation, the degree of emergency, etc., on the monitor of the handling-operator terminal device 20.

[0023] Sixthly, the alarm management apparatus 10 makes a request for approval of the alarm handling operation (refer to Fig. 1(a-6)).　For example, the handling-operator O performs an operation of clicking an "approval request" button on the alarm handling flow screen that is displayed on the monitor of the handling-operator terminal device 20.　The alarm management apparatus 10 also displays the type of content of work in the alarm handling operation that the handling-operator O is to perform, a message requesting approval, and an approval request screen, such as an "approval" or "rejection" button on a monitor of the higher-operator terminal device 30.　The higher-operator M checks the approval request screen that is displayed on the monitor of the higher-operator terminal device 30 and selects "approval" or "rejection" on the approval request screen.

[0024] Seventhly, the handling-operator O inputs the content of handling (refer to Fig. 1(a-7)).　For example, the handling-operator O performs an operation of clicking "in handling work" on the alarm handling flow screen that is displayed on the monitor of the handling-operator terminal device 20 and inputs the status of implementing the handling work to a displayed text input screen.

[0025] Eighthly, the handling-operator terminal device 20 transmits input information (refer to Fig. 1(a-8)).　For example, the handling-operator terminal device 20 transmits the status of implementing the content of work to the alarm management apparatus 10 as the input information that is input by the handling-operator O.

[0026] Ninthly, the alarm management apparatus 10 shares the status of the alarm operation (refer to Fig. 1(a-9)).　For example, the sharing-operator C performs an operation of clicking an "in handling work" button on the alarm handling flow screen that is displayed on the monitor of the sharing-operator terminal device 40 and checks the displayed status of performing the alarm handling operation performed by the handling-operator O that is displayed.

[0027] 1-2-2. Alarm Shelving Flow Screen Management Process First of all, the alarm management apparatus 10 makes a notification of an alarm (refer to Fig. 1(b-1)).　For example the alarm management apparatus 10 transmits an alarm representing an abnormality in a process and generated in a plant to the handling-operator terminal device 20.

[0028] Secondly, the handling-operator O selects an alarm shelving operation as an alarm operation (refer to Fig. 1(b-2)).　For example, the handling-operator O selects the alarm shelving operation on an alarm summary display screen that is displayed on the handling-operator terminal device 20.　The handling-operator terminal device 20 transmits the selection of the alarm shelving operation to the alarm management apparatus 10.

[0029] Thirdly, the alarm management apparatus 10 generates an alarm shelving flow screen as a flow screen (refer to Fig. 1(b-3)).　For example, the alarm management apparatus 10 generates the alarm shelving flow screen presenting a flow of a procedure of performing the alarm shelving operation based on the type of the generated alarm, the location of generation, the degree of emergency, etc.　In the example in Fig. 1(b-3), a flow screen presenting the flow of the procedure of "input reason or purpose"→"make request for approval"→"in shelving" is generated.

[0030] Fourthly, the alarm management apparatus 10 displays the alarm shelving screen as a flow screen (refer to Fig. 1(b-4)).　For example, the alarm management apparatus 10 displays the flow screen presenting the flow of the procedure of "input reason or purpose"→"make request for approval"→"in shelving" as the alarm shelving flow screen on a monitor of the handling-operator terminal device 20 that the handling-operator O uses.　The alarm management apparatus 10 may present the progress of the alarm shelving operation by displaying a button, such as "input reason or purpose", in a colored manner (refer to the slashed portion in Fig. 1(b-3)).

[0031] Fifthly, the handling-operator O inputs a reason or a purpose (refer to Fig. 1(b-5)).　For example, the handling-operator O performs an operation of clicking an "input reason or purpose" button on the alarm handling flow screen that is displayed on the monitor of the handling-operator terminal device 20 and inputs the reason or purpose of selecting the alarm shelving operation to a displayed text input screen.

[0032] Sixthly, the handling-operator terminal device 20 transmits input information (refer to Fig. 1(b-6)).　For example, the handling-operator terminal device 20 transmits the reason or purpose of selecting the alarm shelving operation to the alarm management apparatus 10 as input information that is input by the handling-operator O.

[0033] Seventhly, the alarm management apparatus 10 makes a request for approval of the alarm shelving operation (refer to Fig. 1(b-7)).　For example, the handling-operator O performs an operation of clicking a "make request for approval" button on the alarm shelving flow screen that is displayed on the monitor of the handling-operator terminal device 20.　The alarm management apparatus 10 displays the reason or purpose of selecting the alarm shelving operation that is input by the handling-operator O, a message requesting approval, and an approval request screen, such as an "approval" or "rejection" button on the monitor of the higher-operator terminal device 30.　The higher-operator M checks the approval request screen that is displayed on the monitor of the higher-operator terminal device 30 and selects "approval" or "rejection" on the approval request screen.

[0034] Eighthly, the alarm management apparatus 10 shares the status of the alarm operation (refer to Fig. 1(b-8)).　For example, the sharing-operator C performs an operation of clicking an "input reason or purpose" button on the alarm shelving flow screen that is displayed on the monitor of the sharing-operator terminal device 40 and checks the displayed reason or purpose of selecting the alarm shelving operation that is input by the handling-operator O.　The sharing-operator C is able to check that "in shelving" is displayed on the alarm shelving flow screen that is displayed on the monitor of the sharing-operator terminal device 40 and recognize that the handling-operator O has not started the alarm handling operation at the present time.

[0035] 1-3. Effect of Alarm Management System 100 The background of the alarm management system 100P according to the reference technique, a function required for the alarm management system 100P, and an overview and problems in the alarm management system 100P will be described and then an effect of the alarm management system 100 will be described below.

[0036] 1-3-1. Background of Alarm Management System 100P The alarm management system 100P is strictly standardized according to international standards, such as ISA18.2 and IEC62682, because of features that are functions for quickly sensing the risks at the plant site, protecting the assets of the company, and protecting the lives of workers who work at the plant site.　According to the above-described standards, basic functions of alarms that the alarm management system 100P should meet are defined as required functions and recommended functions and it is essential for each control system vender to implement the alarm management system 100P according to the above-described standards in the industry.

[0037] In the alarm management system 100P, because various alarms, such as an urgent alarm, a non-urgent alarm, a frequent alarm, and the first alarm, are generated, the handling-operator O who monitors alarms, or the like, is required to promptly determine appropriate measures corresponding to the alarms and implement the measures.

[0038] While how alarms act as functions is standardized, however, there is no strict rule on how the handling-operator O, or the like, who monitors alarms handles the alarms and supports are not provided as a system of the alarm management system 100P currently.　At each plant site, unique rules are often set in the plant site.　For example, there are unique rules, such as necessity of approval of the higher-operator M serving as a superior, or the like, prior to handling of the alarm, necessity of a check by the sharing-operator C who is another operator, or the like, after handling of the alarm, and necessity of keeping a record by the handling-operator O when performing an alarm operation.　A specific way for the unique rules is often implemented by a low-tech method not depending on a control system or by another system.

[0039] Thus, in the alarm management system 100P, an alarm function that a control system includes and that enables assistance in an alarm operation performed by a user, such as the handling-operator O, without straining an alarm model based on ISA18.2 or IEC62682 is required.

[0040] 1-3-2. Function Requiring Alarm Management System 100P The function required for the alarm management system 100P will be described.　First of all, in alarm monitoring, the handling-operator O should try to move apart from the alarm summary screen as little as possible while the alarm is generated.　This is because, at the plant site, a relevant alarm possibly is generated further in a following manner after an alarm is generated or there is possibly a transition with the alarm condition being not stable.　For this reason, it is necessary for the alarm management system 100P to reduce the work of the handling-operator O by assisting with alarm operations and external communication.

[0041] Secondly, it is important to record the status in which the handling-operator O handles an alarm and the reason or purpose of the alarm operation and sharing the information with other members by a simple method makes it possible to prevent confusion at the plant site in advance.　For this reason, it is necessary for the alarm management system 100P to share the status in association with the condition of the alarm in real time by providing support in sharing the above-described status.

[0042] Thirdly, the number of experienced operators decreases and inexperienced operators perform operations and monitoring frequently as the background of the times.　While experienced operator is able to grasp a work order without looking at the handling manual, an inexperienced operator has to check the procedure in many cases.　For this reason, for the alarm management system 100P, a system that enables an experienced operator to check the status of handling in a remote environment is necessary.

[0043] 1-3-3. Overview of Alarm Management System 100P Using Fig. 2, an overview of the alarm management system 100P according to the reference technique will be described.　Fig. 2 is a diagram illustrating an alarm handling operation according to the reference technique.　A basic configuration of the alarm management system 100P will be described and then an overview of a process performed by the alarm management system 100P and problems in the alarm management system 100P will be described below.

[0044] 1-3-3-1. Basic Configuration of Alarm Management System 100P The basic configuration of the alarm management system 100P will be described.　A HMI (Human Machine Interface) function, an alarm manual, and a management representative will be described in order below.

[0045] HMI Function First of all, the HMI function will be described.　A HMI has a function of collecting generated alarms and displaying an alarm message and a current alarm condition.　The handling-operator O is able to know a notification of an alarm and the current alarm condition via the HMI.

[0046] An alarm summary screen displaying function is a HMI function.　The alarm summary screen displays a list of alarms to the handling-operator O and makes a notifications of an alarm using a sign, a character string, sound, or the like.　The handling-operator O is able to perform an alarm check operation, the shelving operation (an alarm shelving function), etc., on the alarm summary screen.　The handling-operator O is able to handle an alarm (such as valve control) via the HMI.

[0047] Alarm Manual Secondly, an alarm manual will be described.　An alarm manual is a handling manual that is defined per alarm.　Alarm manuals are in various media, such as a paper medium or an online manual that is open on an intranet, depending on the plant site.　The alarm manual differs at each plant site and therefore is not prepared by a control system vender but is prepared on a user side using the plant in many cases.

[0048] Management Representative Thirdly, a management representative, such as a superior or a higher-operator M, will be described.　When a measure of some kind is implemented against an alarm or after an alarm is handled, an approval or check of the management representative, such as the superior or the higher-operator M, is necessary in many plant sites.　Particularly, for measures having effects on the behavior of alarms, such as the alarm shelving operation, not only approval but also keeping a record of the purpose and reason of the alarm shelving operation are required not infrequently.

[0049] 1-3-3-2. Overview of Process Performed by Alarm Management System 100P Using Fig. 2, the overview of the process performed by the alarm management system 100P will be described.　In the alarm management system 100P, particularly as for generation of alarms, the handling-operator O keeps opening the alarm summary screen and is conducting operations and a monitoring operation while paying attention to whether an alarm necessary to handle is generated.　The handling-operator O displays alarms in a sorted manner in line with preferences of the handling-operator O in an order of priorities or in an order of generation on the alarm summary screen so as to focus on one that has to be handled quickly.

[0050] In the example in Fig. 2, the handling-operator O performs the alarm handling operation as follows.　First of all, the handling-operator O makes a check on whether an alarm is generated from the alarm summary screen displayed on the monitor of the handling-operator terminal device 20 (refer to Fig. 2(1)).　Secondly, when an alarm is generated, the handling-operator O makes a check on the alarm manual (handling manual) necessary handle alarms (refer to Fig. 2(2)).　Thirdly, the handling-operator O makes a request for approval of handling the alarm to the higher-operator M who is the management representative as required (refer to Fig. 2(3)).　Fourthly, the higher-operator M gives approval of handling the alarm (refer to Fig. 2(4)).　Fifthly, the handling-operator O handles the alarm using the handling-operator terminal device 20 (refer to Fig. 2(5)).　Sixthly, when the alarm is handled, the handling-operator O makes a report and a check on the result of handling the alarm.

[0051] In the process performed by the alarm management system 100P, the handling-operator O sometimes moves apart from the HMI, that is, the handling-operator terminal device 20 as required.　In the alarm management system 100P, a plurality of alarms are sometimes generated concurrently and therefore, if an order of priorities, a time necessary for handling, etc., are set, more complicated procedure is necessary.

[0052] In the alarm management system 100P, a function of, when an alarm having a higher priority appears at the same time, shelving an alarm having a lower priority (alarm shelving function) is defined as an essential function according to ISA18.2 and IEC62682.　Using the above-described alarm shelving function, the handling-operator O performs the alarm shelving operation in order to concentrate on other works.　The handling-operator O performs the alarm shelving operation also with intent to hide the alarm having a lower priority temporarily in order to concentrate on handling the alarm having a higher priority.　Because of features that the alarm shelving operation however hides an alarm, approval of the higher-operator M, or the like, is necessary or a rule of leaving the reason and the purpose is set in many plant sites.

[0053] In a specific example, the handling-operator O performs the alarm shelving operation as follows.　First of all, the handling-operator O makes a check on whether an alarm is generated from the alarm summary screen that is displayed on the monitor of the handling-operator terminal device 20.　Secondly, when an alarm is generated, the handling-operator O determines to perform the alarm shelving operation and determine a time during which handling the alarm is suspended.　Thirdly, the handling-operator O records the reason or purpose of performing the alarm shelving operation.　Fourthly, the handling-operator O makes a request for approval of shelving the alarm to the higher-operator M who is the management representative.　Fifthly, the higher-operator M gives approval of shelving the alarm.　Sixthly, the handling-operator O performs the alarm shelving operation using the handling-operator terminal device 20.

[0054] In the above-described process performed by the alarm management system 100P, the handling-operator O may move apart from the HMI, that is, the handling-operator terminal device 20 as required.

[0055] In addition to the above-described process performed by the alarm management system 100P, there are more alarm operations and cases of handling and the rules and the status differ in each plant site.

[0056] 1-3-3-3. Problems of Alarm Management System 100P The problems of the alarm management system 100P will be described.　Problem 1 relating to the handling-operator O, Problem 2 relating to the higher-operator M, and Problem 3 relating to the sharing-operator C will be described in order.

[0057] Problem 1 First of all, Problem 1 relating to the handling-operator O will be described.　It is necessary for the handling-operator O to look away from the HMI in order to check the handling manual and have communication with the higher-operator M.　For this reason, there is a possibility that the status changes, for example, the status of the alarm changes and furthermore an alarm having a higher priority is generated while the handling-operator O looks away, which leads to a risky condition in some cases.

[0058] Problem 2 Secondly, Problem 2 relating to the higher-operator M will be described.　When the handling-operator O makes a request for approval to the higher-operator M, or the like, it is necessary to obtain a capture image, make a memo of an ID, or the like, for specifying the type of an alarm, and make a report to the higher-operator M, or the like, in order to deliver information on the alarm, etc.　The above-described task for the handling-operator O to commutate with the higher-operator M, or the like, prevents the handling-operator O to work, which leads to a cause of a delay in handling in some cases.

[0059] Problem 3 Thirdly, Third Problem 3 relating to Sharing-operator C will be described.　In some cases, sharing information delays, for example, the sharing-operator C is unable to know the situation of the handling-operator O and is notified orally later.　For this reason, in some cases, the sharing-operator C deals with the alarm redundantly or the reason or purpose of handling are not shared and the alarm disappears suddenly, which leads to a confusion.

[0060] 1-3-4. Overview of Alarm Management System 100 An overview of the alarm management system 100 will be described.　The alarm handling flow screen management process and the alarm shelving flow screen management process will be described below in order.

[0061] Alarm Handling Flow Screen Management Process The alarm management system 100 executes the alarm handling flow screen management process as follows.　First of all, the alarm management apparatus 10 transmits an alarm.　Secondly, the handling-operator O selects the alarm handling operation as an alarm operation.　Thirdly, the alarm management apparatus 10 generates the alarm handling flow screen as a flow screen.　Fourthly, the alarm management apparatus 10 displays the alarm handling flow screen as a flow screen.　Fifthly, the handling-operator O checks the handling manual.　Sixthly, the alarm management apparatus 10 makes a request for approval of the alarm handling operation.　Seventhly, the handling-operator O inputs content of handling.　Eighthly, the handling-operator terminal device 20 transmits input information.　Ninthly, the alarm management apparatus 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 of all, the alarm management apparatus 10 transmits an alarm.　Secondly, the handling-operator O selects the alarm shelving operation as an alarm operation.　Thirdly, the alarm management apparatus 10 generates the alarm shelving flow screen as a flow screen.　Fourthly, the alarm management apparatus 10 displays the alarm shelving flow screen as a flow screen.　Fifthly, the handling-operator O inputs a reason or a purpose.　Sixthly, the handling-operator terminal device 20 transmits input information.　Seventhly, the alarm management apparatus 10 makes a request for approval of the alarm shelving operation.　Eighthly, the alarm management apparatus 10 shares the status of the alarm operation.

[0063] 1-3-5. Effects of Alarm Handling System The effects of the alarm management system 100 will be described.　Effect 1 relating to the handling-operator O, Effect 2 relating to the higher-operator M, and Effect 3 relating to the sharing-operator C will be described in order.

[0064] Effect 1 First of all, Effect 1 relating to the handling-operator O will be described.　In the alarm management system 100, the operations previously performed by an external system or another medium such as displaying of a manual, approving and checking, and inputting of the reason of the shelving operation can be completed by the handling-operator O within the system.　Thus, the time the handling-operator O moves away from the HMI can be reduced, and the handling-operator O can focus on monitoring of alarms.　In the alarm management system 100, the system aligns systems for approving and checking and thus notifies an approver or a checker, such as the higher-operator M, of information on and the condition of the alarm, which omits the task for the handling-operator O to explain the status.

[0065] The alarm management system 100 provides navigation in a work procedure about the alarm handling procedure using the flow screen, which enables the inexperienced operator O to handle smoothly and enables the experienced sharing-operator C to give support by checking in a remote environment.

[0066] Effect 2 Secondly, Effect 2 relating to the higher-operator M will be described.　In the alarm management system 100, the approver or the checker, such as the higher-operator M, is notified by the system (by chat in the system or by an external medium, such as an electric mail) and thus is able to know there is a request.　In the alarm management system 100, the higher-operator M is able to check the content of the notification and perform an approving or checking operation via the system or an operation via an electric mail or a web page.　In the alarm management system 100, a request notification is added with a memo, such as information on and the current condition of a subject alarm and the reason or purpose of an operation performed by the handing operator O, which makes it possible to recognize the content of the subject request without a person in charge of handling.

[0067] Effect 3 Thirdly, Effect 3 relating to the sharing-operator C will be described.　In the alarm management system 100, the sharing-operator C is able to check the status of handling an alarm from the flow screen.　In the alarm management system 100, when someone proceeds with handling, the sharing-operator C introduces a system that implements an exclusion logic to prevent the sharing-operator C from handling and accordingly redundant handling does not occur.　In the alarm management system 100, also when the condition of the alarm changes because of the alarm shelving operation, or the like, the status is checked via the flow screen and the reason or purpose are shared, which makes it possible to avoid confusion.
