Abstract

PROBLEM TO BE SOLVED: To prevent the omission of necessary countermeasure with respect to faults caused in the system or duplicating countermeasures with respect to one and the same fault in the case that maintenance people in existence at plural points monitor the same system. SOLUTION: Plural maintenance persons conduct the monitoring of the fault state of a monitor object system 1 the fault of which is autonomously attained, by using a monitor controller 2 and a monitor terminal 3 connected via an information transfer network 6. A maintenance person that countermeasures the fault declares to the other maintenance persons that he will countermeasure the fault (called fault recognition). Then when the fault recognition is conducted by plural maintenance persons nearly at the same time, the monitor controller 2 centrally manages the recognition information and validates the fault recognition by only one person. Thus, the maintenance persons other than the maintenance person who is taking countermeasures on the fault can recognize the countermeasure state of the fault.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fault monitoring and management system, and more particularly to monitoring faults of a monitored system having a function of autonomously detecting a fault from a plurality of points using the same fault information. The present invention relates to a system for monitoring and managing faults in a system having such a maintenance form.

[0002]

2. Description of the Related Art The prior art fault monitoring and management system for a monitored system has a large or small scale, but a fault occurring in the monitored system is intensively performed by a single fault monitoring device installed at an arbitrary location. It is common to be done.

FIG. 10 is a diagram for explaining a fault monitoring management method for a monitored system according to the prior art.
A fault monitoring management method according to the related art will be described with reference to FIG. In FIG. 10, 1 is a monitoring target system, 2 is a monitoring control device, 5 is a maintenance person, 1-a is a network component device, and 1-b is a connection line.

[0004] In the fault monitoring and management system according to the prior art shown in FIG. 10, a plurality of network components 1-a and connection lines 1-b connecting these devices are used as a system 1 to be monitored.
This is an example of a network system composed of the following. A monitoring target system 1 is provided with one monitoring control device 2.

[0005] In the fault monitoring and management system shown in FIG. 10, when a fault occurs in a part of the monitored system 1, information on the fault is sent to a maintenance person 5 of the system monitoring by the monitoring control device 2. Notified. The system maintainer 5 that recognizes the failure based on the notification gives a response to the failure by giving an instruction to a person deemed appropriate for dealing with the failure, such as a maintenance person located near the failure occurrence device. At this time, the maintainer 5 may, if necessary, use the Trouble Tick as one of the methods for managing from the occurrence of the failure to the recovery.
et had been issued.

[0006] The Trouble Ticket is issued when Trouble occurs.
It is issued by the ble Ticket administrator and passed to the appropriate person for troubleshooting. The maintainer with the Trouble Ticket must take responsibility for troubleshooting. At this time, it is possible to give the trouble ticket to the maintenance person who seems to be more appropriate if necessary.
The maintainer holding the icket must take some action. The Trouble Ticket ends when it is confirmed that the trouble has been recovered. The contents described in the Trouble Ticket are the date and time of occurrence of the failure, the location, the name of the device, the type of the failure, the coping action (the coping person) and the like. Trou like this
By using the ble Ticket, the person responsible for troubleshooting can be clarified, and appropriate failure management can be performed.

On the other hand, a recent system maintenance mode is shown in FIG.
0 to a maintenance mode in which the same fault information is provided to a plurality of points and a fault can be monitored at a plurality of points at the same time. It is changing.

FIG. 11 is a diagram for explaining a conventional fault monitoring and management system for providing the same fault information to a plurality of points. This will be described below. In FIG. 11, 3
Is a maintenance terminal, and other symbols are the same as those in FIG.

In the fault monitoring management system according to the prior art shown in FIG. 11, a plurality of network components 1-a and connection lines 1-b connecting these devices are also used as the system 1 to be monitored.
This is an example of a network system composed of the following. In the fault monitoring method shown in FIG. 11, one monitoring control device 2 is provided in the monitoring target system 1, and the network system to be monitored is divided into a plurality of districts, and the portions included in the districts are individually divided. A maintenance terminal 3 for monitoring is provided for each district and connected to the monitoring control device 2,
Further, a maintenance terminal 3 is also connected to the monitoring control device 2.

In the fault monitoring and management system having such a configuration, a fault is limited to an area, and in the case where a fault is sufficient by a countermeasure operation for each area, a monitoring device is installed in each area, and a local area is set there. The maintenance mode of monitoring each time is more effective in cases where it is possible to take an accurate and prompt measure. Also,
The fault monitoring and management system having the configuration as shown in FIG. 11 is used in a system such as a communication network when a system fault that occurs in a part of the area affects other areas. This is also effective when it is required that the information as to whether a failure has occurred can be referred to from other areas. For these reasons, the fault monitoring and management method has shifted to a maintenance form as shown in FIG. 11 which can cope with a fault by monitoring the fault state of the entire system and individual monitoring for each district.

[0011]

The fault monitoring management system for monitoring a system at a plurality of points as shown in FIG. 11 requires a system capable of monitoring a fault of the entire system at a plurality of points. . But in that case,
If only the information on the failure is simply provided, it is unclear whether or not another maintenance person is taking action on the failure. Usually, a maintenance technician is determined for each region or system component device, or a maintenance technician is determined for each type of fault that has occurred.

However, in the fault monitoring and managing system according to the prior art described with reference to FIG. 11, when a maintenance person who is not a direct maintenance person at a remote place sees the same failure occurrence, the maintenance person who is in charge of the failure However, there is a possibility that a failure may be overlooked for some reason, and it is not possible to know whether or not the failure is actually dealt with.
The fault monitoring and management system according to the prior art described with reference to FIG.
If the (region) is ambiguous and information is not sufficiently exchanged, there is a problem that the failure may be dealt with redundantly or may not be dealt with.

[0013] Trouble Ti, which is a means of fault management,
In the case of a maintenance mode in which failures are managed in a concentrated manner as shown in FIG. 10, the issuer of the trouble ticket is uniquely determined, and the issuer is uniquely determined by the ticket issuer by referring to the maintenance range. There was no problem to decide. However, the method of monitoring the monitoring target system using the same fault information at a plurality of points as shown in FIG.
When the method using e-Ticket is applied, there is a problem that the ticket issuer is not uniquely determined.

A system for monitoring a monitored system using the same fault information at a plurality of points as shown in FIG.
As described with reference to FIG. 10, when a method is adopted in which a maintenance person at a certain point centrally manages and issues a ticket,
The meaning of adopting distributed management has diminished. On the other hand, if a maintenance person who recognized a failure issued a ticket individually, the maintenance person in charge would need to provide two or more There is a problem that a ticket is issued.

An object of the present invention is to solve the above-mentioned problems of the prior art, provide fault information of the entire monitored system to a maintenance person in an easy-to-understand manner, and notify each maintenance person of the current handling status of the failure. It is an object of the present invention to provide a fault monitoring management system for monitoring a monitoring target system using the same fault information at a plurality of points where it is possible to prevent missing or double handling.

[0016]

SUMMARY OF THE INVENTION According to the present invention, there is provided a maintenance system for monitoring a failure of a monitoring target system having a function of autonomously detecting a failure from a plurality of locations using the same failure information.

In the fault monitoring management system according to one embodiment of the present invention, a maintenance person monitors faults of the monitoring target system 1 using monitoring terminals installed at a plurality of points, as shown in FIG. A monitoring target system 1, a monitoring control device 2 for monitoring a failure of the monitoring target system, a plurality of monitoring terminals 3 (terminals equivalent to those described as the maintenance terminal 3 in FIG. 11), and a monitoring control It is configured by an information transfer network 6 connecting the device 2 and a plurality of monitoring terminals 3, and a maintenance person 5 monitors using the monitoring terminal 3. The monitoring target system 1 has a function of detecting a fault that has occurred inside itself and notifying the monitoring control device 2 of the detected fault. The monitoring control device 2 includes a plurality of monitoring terminals 3.
Are respectively arranged at arbitrary points via the information transfer network 6. At each point, the system maintenance person monitors the failure of the monitoring target system 1 through the monitoring terminal 3. For emergency response, the monitoring control device 2
As described with reference to FIG. 2, a communication unit for an emergency response maintenance person is provided.

As shown in FIG. 2, the monitoring control device 2 includes a fault management unit 2-b for managing faults that have occurred in the monitoring target system 1, and the monitoring target system 1 as an external interface. Failure monitoring unit 2-a for receiving failure information from the terminal, a monitoring terminal management unit 2-d for communicating with the monitoring terminal 3, and a communication function unit for communicating with a maintenance person who responds in an emergency. 2-c, a maintenance person selection determining function unit 2-e for determining a person in charge of processing a failure, a timer function unit 2-g for obtaining time, and a file 2-f for storing various setting data. It is configured with.

Next, the flow of processing when a failure has actually occurred in the monitored system will be described with reference to FIG.

(1) The monitoring target system 1 notifies the monitoring controller 2 of the occurrence of the failure and the content of the failure when the failure occurs ().

(2) Upon receiving the notification from the monitoring target system 1 that a fault has occurred, the monitoring control device 2 adds the fault information to a list of faults occurring within the monitoring control device 2 and adds the fault information to the monitoring control device 2. To the maintenance person 5 through the monitoring terminal 3 connected to the server. Usually, a plurality of monitoring terminals 3 are connected, and a plurality of maintenance personnel can know the occurrence of a failure ().

(3) One of the maintenance personnel 5 who has been monitoring with the monitoring terminal 3 decides to take a countermeasure operation for the occurred failure. Hereinafter, this will is referred to as recognition of disability ().

(4) Recognition of disability (display of intention to deal with disability)
The maintenance person 5 who has performed the notification notifies the other maintenance person that the failure has been recognized through the monitoring terminal 3. As a result, another maintenance person can know that the failure is being dealt with ().

(5) After that, the maintenance person who has recognized the failure performs responsibilities for the failure with responsibility.

FIG. 3 is a diagram showing an example of a screen on which a notification of a failure is actually sent from the monitoring control device 2 to the monitoring terminal 3 and a maintenance person selects whether or not to recognize the failure. With reference to FIG. 3, an operation of the maintenance person selecting whether or not to recognize a failure will be described.

As shown in FIG. 3, in the display section of the monitoring terminal 3, the list display section shows the failure occurrence date and time, failure type (alarm), failure cause, failure importance, failure According to the present invention, in addition to the occurrence position, the coping status and the coordinator are displayed, so that the maintenance person 5 can obtain information as to whether or not the fault is being coped and who is the coordinator.

The maintenance person 5 can recognize the failure by selecting a left unhandled failure and pressing the recognition button. When the maintenance person 5 selects an unhandled failure and presses the recognition button, the monitoring terminal 3
Is identified as a cognitive person of the fault, and the supervisory control device 2 is notified of the cognitive fault. By performing this recognition, the change of the coping status and the coordinator's name are notified to all the monitoring terminals 3.

When a fault is recognized by mistake, the fault can be canceled by selecting the fault and pressing a cognitive state change button. In this case, only the person who has made the recognition can perform the cancellation. Further, the cancellation is notified to each monitoring terminal 3 as in the case of the above-described recognition, and the recognition from the maintenance person is requested again. When the screen is closed without performing the recognition, by pressing the close button, the failure list screen can be closed.

FIG. 4 is a diagram for explaining the flow of processing when two or more maintenance personnel have performed recognition at the time of occurrence of a fault, and FIG. FIG. 6 is a diagram showing an example, and FIG. 6 is a diagram showing an example of judgment criterion data for determining a maintenance person in charge by determining a maintenance area. Hereinafter, referring to FIGS. The determination of the maintenance person in the case where the maintenance is performed will be described.

Examples of situations where recognition is performed by a plurality of maintenance personnel include: a. When the scope of maintenance is not clearly defined, b. If the same disability affects multiple areas, c. If a failure occurs near the boundary of the maintenance area, d. Due to the redundant configuration of the maintenance system,
There are cases where the maintenance ranges are overlapped, and in such a case, a plurality of maintenance personnel recognizes. First, the processing procedure will be described with reference to FIG.

(1) A plurality of maintenance personnel make a cognitive declaration almost at the same time.

(2) The monitoring terminal manager 2-d in the monitoring controller 2 receives the recognition information sent from each monitoring terminal 3 ().

(3) The monitoring terminal manager 2-d arranges the received recognition information in a queue 2-h in the order of arrival. This is necessary for organizing the information sent from the monitoring terminal that is sent irregularly.

(4) The fault management unit 2-b reads fault recognition information from the queue 2-h. Here, when there are a plurality of cognitive notifications for the same failure, the occurring failure management unit 2-b determines a maintenance person to accept according to a predetermined rule ().

The rules for determining the cognitive maintainer described above are, for example, as follows. Example 1 When a maintenance person who has performed recognition with a predetermined maintenance area does not match the maintenance area of the maintenance person, the recognition is not accepted. Example 2 Assume that the order of acceptance of the failure recognition notification is first-come-first-serve. Example 3 A maintenance person in charge is defined in advance according to a failure type and a device type. If the maintenance person who has performed the recognition does not match the person in charge, the recognition is not accepted.

(5) The occurring fault management unit 2-b performs management by associating the determined cognitive maintenance person with the fault information, and notifies each maintenance person who is monitoring the fault through each monitoring terminal 3 of the fault. Notify who the recognition was made by ().

FIG. 5 shows an example of the fault information managed by the monitoring fault list of the monitor and control unit 2 in the above description. The example shown in FIG. 5 shows information on one occurring fault, and the list of occurring faults displays information as shown in FIG. 5 for all currently occurring faults. In the illustrated example, “item number”, “information name”, and “content” are shown, and “information name” includes “fault identifier”, “fault occurrence date and time”, “alarm”, “factor”, and “severity level”. , "Failure location", "Response status", "Responsor", "Response history"
Is exemplified.

FIG. 6 shows an example of the criterion data for determining the maintenance person in charge of the failure by defining the maintenance area shown in the first example of the rule for determining the cognitive maintenance person. In the example shown in FIG. 6, administrative "city" is defined as a maintenance area, and a maintenance person name is registered corresponding to these areas. In this way, by defining the maintenance person in charge for each region (or equipment installation location, etc.),
This can be used as a criterion when a plurality of maintenance personnel make a failure recognition declaration.

In the above description, a method has been described in which a single maintenance person is designated as a trouble-shooting maintenance person when a plurality of maintenance people recognize a failure. However, the present invention is based on the above-described criterion data. Thus, a plurality of maintenance personnel can be determined by assigning priorities to a plurality of maintenance personnel.

Normally, in the fault monitoring, a maintenance person in charge is determined for each device constituting the system, and a failure that has occurred in the device is immediately recognized and dealt with by the maintenance person. It is unlikely to be left alone. But,
A failure may be overlooked for a long time due to some circumstances, such as oversight of the failure, absence of a maintenance person at night, and failure of the monitoring terminal itself. In such a case, the maintenance person monitoring at another point may notice, but the maintenance person at another point may not notice. It is not desirable to leave the fault for a long time.

In the embodiment of the present invention, this is detected by the monitoring and control device, and a maintenance person for emergency response is notified,
The maintenance person can deal with the failure.

FIG. 7 is a diagram for explaining the flow of processing when a fault occurs and nobody recognizes the fault and the fault is abandoned. Referring to FIG. A description will be given of a processing procedure for notifying a maintenance person for emergency response in the case of being recognized.

(1) When a failure occurs in the monitored system 1, the monitored system 1 that has detected the failure notifies the monitoring control device 2 of the occurrence of the failure ().

(2) Upon receiving the notification of the occurrence of the failure from the monitoring target system 1, the occurring failure management unit 2-b of the monitoring control device 2 adds the failure information to the occurring failure list ().

(3) The monitoring terminal management unit 2-d notifies each monitoring terminal 3 that a new fault has occurred in the monitoring target system 1 ().

(4) The fault management unit 2-b monitors the elapsed time after the fault is generated by the timer function unit 2-g.
If the maintenance person does not recognize the failure for a certain period of time (can be set arbitrarily), this is detected as leaving the failure ().

(5) Upon detecting the above-mentioned failure, the failure management unit 2-b notifies the maintenance person 4 for emergency response that the failure has occurred and has been left. As the notification means in this case, means such as a mail, a pager, a telephone, and a dedicated line can be used ().

(6) Upon receiving the notification, the emergency response maintenance person 4 performs processing such as requesting a maintenance person who is deemed to be appropriate to prevent the failure.

As described above, the maintenance person near the monitoring terminal 3 or the emergency response maintenance person knows the failure of the monitored system, recognizes the failure, and declares that the failure should be dealt with. Was explained. According to the embodiment of the present invention, a maintenance person who has recognized a failure can automatically monitor a coping action by monitoring an action performed after the recognition, and an example of a process in this case will be described. I do.

(1) As described above, when a failure occurs in the system to be monitored, the monitoring and control device 2 requests the maintenance person to deal with the failure, and the maintenance person recognizes the failure to deal with the failure. Declaration to do.

(2) The supervisory control device 2 uses the reception time of the recognition as the time when the maintenance person starts the coping action, and manages the coping start date and time by including the coping start date and time in the failure information. This allows the other maintainers to know how much time has passed since the cognitive maintainer started to take action.

(3) Further, the monitoring control device 2 positions actions performed by the maintenance person who has performed recognition on the monitoring terminal from recognition to recovery from the failure as failure handling actions, and combines these actions with the failure information. Manage. This allows other maintenance personnel to know what measures have been taken to date for the failure.

(4) Further, the monitoring control device 2 continuously monitors the change in the failure state of the monitored system 1 and positions the change in the failure state as the failure handling action by the maintenance maintainer. For example, when the base of the device of the monitoring target system 1 fails, the failed base is removed and a new base is mounted. At this time, the failure state changes from the base failure to the non-installed base, and then returns to the normal state. The monitored system 1 is notified of such a change in the failure state, and the monitored system 1 notifies the monitoring control device 2. As a result, a trouble-shooting action performed on the device by the troubleshooter can be obtained.

(5) As described above, the monitoring control device 2
By monitoring the change in the failure state of the monitored system 1, the time at which the failure has recovered can be automatically detected and reflected in the failure information. However, when the type of the fault occurring for the same device of the monitored system 1 changes (for example, when the status changes from a base failure to a non-mounted base),
Since the failure has not been completely recovered, the monitoring and control device 2 manages the failure before and after the change in association with each other.

FIG. 8 is a flowchart for explaining a procedure for notifying a maintenance person of a failure state monitored by the monitoring control apparatus. FIG. 9 is a flow chart for allowing the maintenance person to recognize the failure when a failure occurs.
FIG. 10 is a flowchart for explaining a procedure for managing the process from the reception of the recognition to the recovery from the failure. Hereinafter, with reference to FIGS. 8 and 9, the basic processing procedure for performing the failure monitoring described above will be described. explain. This processing procedure is shown in FIG.
It can be divided into two procedures shown in FIG.

First, a procedure for monitoring a fault condition will be described with reference to a flow chart shown in FIG.

(1) The monitoring control device 2 initializes information necessary for monitoring a failure of the monitored system 1 (step 81).

(2) Processing fault monitoring unit 2 of monitoring control device 2
-A monitors the failure state of the monitored system 1 and collects failure information. This monitoring is performed until the occurrence of a failure is detected (steps 82 and 83).

(3) When the occurrence of a failure is detected in step 83, the failure is added to the list of occurring failures in the occurring failure management unit 2-b (step 84).

(4) The monitoring terminal management unit 2-d notifies the monitoring terminal 3 of information on a newly generated failure. The notification of the failure information is continuously performed in response to a request from the monitoring terminal 3 (step 85).

(5) The management of the fault that has occurred is transferred to the fault management part 2-b during occurrence, and the processing fault monitoring part 2-a returns to the processing from step 81 and continues monitoring the fault (step 86).

(6) The management of the occurring fault is performed by the currently generated fault management unit 2-b to which the management of the generated fault has been transferred (step 87).

Next, the processing procedure in the above-described step 87 in the occurring fault management unit 2-b to which the management of the generated fault has been transferred will be described with reference to the flow shown in FIG.

(1) The occurring fault management unit 2-b initializes information necessary for managing the generated fault (step 91).

(2) Wait for a declaration of recognition from the maintenance person through the monitoring terminal 3, accept the recognition, and detect whether or not recognition has occurred (steps 92 and 93).

(3) If no recognition is detected in step 93, the time from the occurrence of the failure is measured.
Then, the process returns to the step (1) to continue the process of waiting for the recognition declaration (step 94).

(4) If the time measurement in step 94 indicates that the fault limit time has been exceeded, the fault has been left to the maintenance person for emergency response by telephone, pager, mail, or the like. Is notified (step 95).

(5) The system waits until the maintenance person for emergency response recognizes the failure and detects it (steps 96 and 97).

(6) When it is detected in step 97 that the failure has been recognized from the maintenance person for emergency response, or in step 93, the failure from the maintenance person has not occurred within the failure limit time. When it is detected that the user has been recognized, the coping status managed as the fault information is changed to coping, and the coordinator is written (step 98).

(7) Notify each monitoring terminal 3 that the failure has been recognized, and inform the maintenance person managing each monitoring terminal 3 that the maintenance person who has performed the recognition will deal with the failure. (Step 99).

(8) Thereafter, a change in the state of the failure due to the work of the maintenance person dealing with the failure is monitored as a failure handling status, and the process is terminated after recovery from the failure.

According to the above-described embodiment of the present invention, the flow of information relating to a fault can be not one-way from the monitoring control device to the maintenance person, but two-way in which information is exchanged with each other. It is possible to provide more information on the failure to the maintenance person, and it is possible to significantly reduce inappropriate responses to the failure such as leaving the failure or performing double measures.

[0079]

As described above, according to the present invention, in a fault monitoring and management system of a maintenance system for monitoring a monitored system at a plurality of points, fault information of the entire monitored system is provided to a maintenance person. Since each maintenance person can also be notified of the current handling status of the failure, it is possible to prevent a failure to deal with the failure and prevent double handling.
