[0003]

However, in the above-mentioned conventional technique, since only the fault alarm sent from the monitored system is displayed, even if a plurality of fault alarms occur at the same time, the cause of the fault is an arbitrary communication. It is difficult to determine whether it is caused by a device failure or a cause other than a communication device failure such as a regional earthquake or weather.

An object of the present invention is to provide a monitoring device and a display system that facilitate the cause analysis of an alarm occurrence in a monitoring system for monitoring a system having a regional spread such as a communication network.

Another object of the present invention is to provide a monitoring device and a display system that facilitate the investigation of the cause, especially when a plurality of failures occur simultaneously.

[0006]

In order to achieve the above object, according to the present invention, a system other than the system to be monitored or a measuring device for measuring disaster information in the system to be monitored is used to measure weather information such as earthquake or weather or news. The present invention is characterized in that a means for acquiring disaster information such as information and a display means for displaying the related disaster information by overlapping the acquired disaster information on a screen displaying the state of a system having a geographical spread are provided.

More specifically, according to the present invention, a means for storing disaster tolerance information to be monitored, and a processing unit for calculating the degree of association between a disaster and a failure based on the disaster tolerance information and the acquired disaster information. A display means for reflecting the processing result in the background color of the system status screen and the shade of the color is provided.

[0008]

According to the present invention, the disaster display means for displaying disaster information such as seismic intensity, rainfall, wind force, etc. other than the monitoring information necessary for monitoring the system to be monitored on the display screen in association with the system status screen is the same. The operator can view the disaster information and the failure information in association with each other on the screen, which facilitates the operator's work of checking the relationship between the cause of failure and the disaster.

[0009]

[Embodiment 1] FIG. 1 is a block diagram showing an embodiment of a wide area fault display system according to the present invention. The network management system 1 retrieves appropriate disaster information from the communication control unit 10 that communicates with the managed network 2, the database 11 that stores information necessary for disaster display and fault display, and the confidence that a fault has occurred due to a disaster. Work memory 12 for storing calculation results, program memory 13 for storing a program group for displaying failure information and disaster information on a display screen, and a signal processing unit for executing a program existing in the program memory ( CP
U) 14, Display device for displaying system status (CR
T) 15, a keyboard 16 for acquiring commands and information from an operator, a mouse 17, and an input / output control unit 18 for controlling screen display information and keyboard input.

The database 11 stores a failure alarm table 110 for storing failure alarms sent from the constituent elements of the managed network, and disaster countermeasure information such as seismic resistance and water resistance of the constituent elements of the network. Disaster information table 111, component / display element correspondence table 11 required to display the network configuration
2, the screen hierarchy relation table 113, the screen / display element correspondence table 114, the background image color of the system status screen and the color depth thereof are stored with respect to the certainty factor indicating the possibility of failure occurrence due to a disaster described later. A disaster display color table 115, a background screen configuration table 116 that stores the configuration of the background image of the display screen, and the like are stored.

Further, in the program memory, a fault display program 130 for changing the color of the display element of the system status screen based on the fault alarm sent from the managed network 2, a disaster for inputting and displaying wide area disaster information. An information input / output program 131 and a confidence factor calculation program 132 for calculating the relationship between a failure occurrence and a wide area disaster based on the acquired disaster information are stored.

Next, the operation of disaster display by the wide area fault display system will be described with reference to FIGS. 1 to 18.

FIG. 2 shows a flow chart of the disaster display operation.

In the network management system 1, when a failure occurs in a component in the managed network 2, the communication controller 10 receives a failure alarm from the component. Then, the display element corresponding to the component for notifying the failure alarm is obtained from the correspondence between the network component 302 and the display element 301 in the component / display element correspondence table 112 as shown in FIG. A failure alarm table 110 is created with the display element group obtained in step S20 and stored in the database 111 (step 20).
1).

The signal processing unit 14 uses the fault display program 130 to set the display color of the display elements stored in the fault alarm table 110 from green to red. Here, the display color of the display element represents the state of the constituent element corresponding to the display element, and the normal state is set to green and the abnormal state is set to red. Further, in the network display by the hierarchical network map as shown in FIG. 5, as shown in FIG. 6, the display symbol 601 corresponding to the component level screen is displayed in the upper screen 602 of the component level screen 603. Exists. For this reason, the display color of the display symbol of the component level screen including the display element indicating the occurrence of the failure is set from green to red so that the location of the failure can be seen on the upper screen (step 20).
2).

For example, when the network status display screen 701 as shown in FIG. 7 is displayed on the display device 15, the managed symbols included in the display symbols Ochanomizu 702, Shinjuku 703, Shibuya 704, Yokohama 705, and Hachioji 706. Assume that a network element has failed. At this time, from the correspondence relationship between the display elements in the constituent / display element relationship table and the screens at the constituent level, the constituent level screens including the display elements indicating the failure status can be obtained. Then, the display icon on the upper screen such as Ochanomizu and Shinjuku is obtained from the screen hierarchy relation table composed of the display icon 801 and the background screen 802 displayed by the icon as shown in FIG. As a result, the network status display screen is Ochanomizu 702, Shinjuku 703, as shown in FIG.
The color of the display symbols of Shibuya 704, Yokohama 705, and Hachioji 706 becomes red to indicate that a failure has occurred.

Further, as shown in FIG. 10, the background screen 10
01 and the screen hierarchy relation table 113 configured by the display symbol 1002 included in the background screen, the color of the display icon existing in the upper screen of the hierarchical network map group is similarly changed.

Next, the operation menu 70 on the display screen 701
The disaster information menu 708 in 7 is selected by the operator, and a menu 1101 representing the type of disaster information as shown in FIG. 11 is displayed on the screen. The operator specifies the type of disaster information acquired from the telephone line or the television from the menu 1101 indicating the type of disaster information.

When the operator selects the type of disaster information, the signal processing unit 14 sends a command for opening a window for inputting disaster information to the input / output control unit 18 according to the disaster information input / output program 114. The input / output control unit 18 opens a window for acquiring disaster information. An example of the newly displayed window is shown in FIG. In a window 1201 for inputting disaster information, a name 1202 of a display element or a display symbol included in the display screen and a disaster information input field 1203 for inputting disaster information for the display element or the display symbol
There is. The operator inputs disaster information into the disaster information input field 1202 of this window to obtain disaster information (step 203).

When the disaster information acquired by the operator is acquired from the disaster information input field 1202 on the display screen, the input / output control unit 18 notifies the signal processing unit 14 that the disaster information has been acquired. The signal processing unit 14 causes the disaster information input / output program 131 to store a disaster information storage table, which includes a display element 1301, disaster information 1302 for the display element, and a certainty factor 1303 described later, in the work memory 12 as shown in FIG. First, the disaster information obtained for each display element is stored (step 20).
4). If the acquired disaster information is a display symbol unit, the display element included in the display symbol that has acquired the disaster information from the component / display element correspondence table 112, the screen hierarchy relation table 113 and the screen / display element correspondence table 114 is searched for. , Create the disaster information storage table for the display element.

Next, the signal processing unit 14 uses the certainty factor calculation program 132 stored in the program memory 13 to determine the certainty factor P _ij indicating the possibility of failure occurrence due to the designated disaster for each display element that has acquired the disaster information. Calculate to.
The calculation of the certainty factor P _ij follows the formula described below. The calculation result is stored in the certainty factor 1303 of the disaster information storage table in the work memory 12 (step 205).

[0022]

## EQU1 ## P _ij = (p _ij -dL _ij ) / (dU _ij -dL _ij ) ... (Equation 1) Here, the subscript i represents the display element, and the subscript j represents the designated disaster.

P _ij is a value from 0 to 1 representing a state in which the disaster j can cause a failure in the display element i to a state in which the failure can be said to be the cause of the failure.
A value close to 1 indicates that the cause of failure is likely to be caused by disaster j, and a value close to 0 indicates that the cause of failure is unlikely to be caused by disaster j. Further, the case where it is considered that the display element i is not affected by the disaster j is 0 or less, and the case where it is considered that the disaster j is extremely affected is 1 or more. Here, p _ij is the disaster information of the disaster j input by the operator to the display element i. Further, dU _ij and dL _ij are stored in the disaster tolerance information table 111 shown in FIG. The disaster information table 111 represents, for each disaster, an area in which it is uncertain to determine whether a failure has occurred in the display element i due to the disaster, and stores the upper and lower limits of the area. is there. Upper limit of disaster tolerance information table 111 dU _ij 140
3 is the value of the parameter representing the disaster j, and the disaster j
Is the smallest value in the area where the display element i is considered to cause a failure, and the lower limit dL _ij 1402 is a value when the failure j may occur in the display element i due to the disaster j. These parameters are determined based on the operator's past experience for each component corresponding to the display element before the network management system is activated, and are stored in the disaster tolerance information table 111 described above.

When this calculation is completed, the signal processing unit 1
In accordance with the disaster information input / output program 132, reference numeral 4 indicates display elements 702 to 70 indicating a failure state, as shown in FIG.
The background constituent images 1503 to 1509 corresponding to 6, 1501, 1502 on a one-to-one basis are obtained. As shown in FIG. 16, this is a background screen 1601, a background constituent image 1602 constituting the background screen 1601, and display elements and display symbols 16 corresponding to the background constituent image.
03 is stored in the background screen configuration table. Then, the disaster display color table 1 as shown in FIG.
The color and shade of each background constituent image are set based on the correspondence between the 15 disaster types 1701 and the certainty factors 1702. The disaster display color table 115 of FIG. 17 sets a dark color when the certainty factor is close to 1, and a light color when the certainty factor is close to 0. The last set value is transmitted to the input / output control unit 18 (step 206).

Further, in the screen higher than the screen of the component level, the average value of the certainty factors of the display elements indicating the fault condition existing in the screen lower than the display symbol is calculated by the formula described below, and the calculated value is calculated. It is the certainty factor of the displayed symbol.

[0026]

[Equation 2] E = ΣP _ij / n (Equation 2) Here, ΣP _ij is the sum of the certainty factors calculated for each display element included in the display symbol. Value of certainty factor P _ij is 0
The following only show that there is no link between disaster and disability, regardless of the magnitude of the value. Therefore, the certainty factors of 0 or less are unified to 0. Those having a certainty factor P _ij of 1 or more are unified to 1 for the same reason. n is the number of display elements included in the display symbol.

The input / output control unit 18 changes the color of the background constituent image on the display screen and the shade of the color to the designated color and its density (step 207). FIG. 18 shows the result calculated on the basis of the disaster information of FIG. 12 displayed on the display screen. The background color of the display element on the screen becomes yellow representing an earthquake, the above-mentioned high confidence value is dark, and the low confidence value is light.

With the above configuration and operation, the operator of the network management system determines how much the disaster affects the managed network in response to the burst failure alarm notified from a plurality of constituent elements at the same time. It can be visually understood by associating it with a geographical relationship, and it becomes easy to quickly estimate the relationship between a disaster and a failure occurrence.

<Embodiment 2> Next, as a second embodiment of the present invention, a measuring device for measuring disaster information is arranged at each geographical base in the managed network, and based on the information obtained from the measuring device. Automatically displays disaster information on the monitoring screen,
After that, a practical example in which a disaster-prone area known from past experience is also displayed on the monitoring screen will be described.

As shown in FIG. 19, the configuration of this embodiment is similar to that of the first embodiment. In the first embodiment, the database 11 includes a disaster information table 117, a base correspondence table 118, and a disaster alert. A disaster-prone area table 119 that stores areas designated as areas is stored, and a disaster information collection program 133 and a disaster-prone area display program 134 are added to the program memory 13. Further, in the managed network 2, a measuring device for measuring disaster information such as seismic intensity, precipitation amount, wind force, etc. is installed for each geographically separated base such as a building unit or a regional unit.

Next, the operation of disaster display by the wide area fault display system will be described with reference to FIGS. 19 to 27.

FIG. 20 shows an operation flowchart of disaster display. First, the signal processing unit 14 periodically acquires disaster information such as seismic intensity, precipitation, and wind power from each site in the managed system 2 via the communication control device 10 by using the disaster information collection program 133, Information is stored in the disaster information table as shown in FIG.
01 is stored for each disaster information 2102 obtained from the base (step 2001).

Next, it is confirmed whether or not there is a failure alarm notified from the managed network (step 2002). If no fault alarm is sent, the disaster information is collected again. If a fault alarm is sent, the signal processing unit 14 uses the fault display program 130 in the program memory 13 to display the display elements and display symbols on the network status display screen in the same procedure as in the first embodiment. Change from green to red (step 201,
202).

Next, the signal processing unit 14 uses the certainty factor calculation program 132 stored in the program memory 13,
Disaster information is calculated for each display element using the disaster-resistant information table 111 and the base correspondence table 118, and the certainty factor P _ij described in the first embodiment is calculated for all disaster information (step 2003).

The base correspondence table 118 represents the constituent elements of the managed network existing in the area in which the measuring equipment for each base is in charge. As shown in FIG.
01 and a display element 2202 corresponding to a component of the managed network are paired. For example, as shown in FIG. 23, a base 2301 has an area 2 with a geographical spread.
If it is representative of 302, then the components of the managed network 2303, 2304, 2 included therein.
The disaster data of 305 and 2306 is the data sent from the site 2301. Each of the above-mentioned components is displayed as an element S
If the display is N1, SN2, SN3, SN4, the base correspondence table is as shown in FIG.

Then, the largest value of the disaster certainty values obtained for each disaster information is taken as the disaster having the influence of occurrence of a failure on the display element. Based on this result, as shown in FIG. 24, on the work memory 112, a certainty factor table including a display element 2401 representing a disaster, the most relevant disaster type 2402, and the certainty factor 2403 in the disaster is created ( Step 2004).

After calculating the certainty factor for each display element, the certainty factor for each display symbol is calculated (step 2005). This is the same procedure as the first practical example,
The confidence factor for each display element included in the lower screen of the display symbol is averaged, and the average value is used as the confidence factor for the display symbol. If there are different types of disaster information for the display elements included in the display symbol, the disaster type is undetermined because the disaster information is complex.

The certainty factor for each display element obtained by the above procedure and the screen / display element correspondence table 114 of FIG.
And the display element included in the screen displayed on the display device 15 is searched. Then, the retrieved display element and the background screen configuration table 116 are used to pick up the background composition image for the failure display element, and the disaster display color table 1
According to No. 15, the color of the background constituent image is set to the disaster color, and the shade of the background color corresponding to the certainty factor is set (step 2).
006). If there are multiple disaster types, and the disaster type is undecided, the background color is changed to light purple indicating that there are multiple disaster types.

The input / output control unit 18 displays the color of the split screen and the shade of the color set by this procedure on the screen of the display device 15 as in the first embodiment (step 207).

Next, the past disaster information display system will be described.

FIG. 25 shows a flowchart of the past disaster information display system.

The signal processing unit 14 uses the disaster frequent occurrence area display program 134 in the program memory, and based on the fault alarm table 110 and the background screen configuration table 116, the background configuration image corresponding to the component generating the fault alarm. 26, it is checked from the disaster-prone area table 119 in which the disaster-prone area is associated with the background composition picture as shown in FIG. 26 (step 2501). Here, the disaster-prone area table 119 of FIG. 26 expresses a disaster-prone area by a background image 2601 and a background composition image 2602, and the disaster 2 that frequently occurs in the area.
603 is stored.

If there is a background composition image corresponding to the disaster information frequent area, it is checked from the disaster information table existing in the work memory 12 whether the types of disaster information are the same (step 2502).

If the types are the same, a command is sent to the input / output control unit 18 to blink the background color in the disaster-prone area as shown in FIG. The input / output control unit 18 blinks the designated background constituent image (step 2503).

FIG. 27 shows that the area of Yokohama is an earthquake-prone area by blinking the background constituent image corresponding to the display symbol of Yokohama.

With the above configuration and operation, the disaster information is automatically taken into the network management system, and the operator of the network management system can know the disaster information from the background color of the network status display screen, and can quickly You can infer the relationship between disasters and the occurrence of failures.

Further, the operator can visually recognize not only the current disaster information but also the disaster-prone areas required from the past disaster situation, and the degree of association between the disaster and the failure occurrence can be strengthened.

<Third Embodiment> Next, as a third embodiment of the present invention, a disaster information display screen and a network status display screen for displaying disaster information such as a river accident or a terrorist incident are displayed on a multimedia compatible display screen. Will be described on the same screen.

Further, the database 11 is further provided with a disaster information acquisition table 120 in which a procedure for acquiring disaster information is stored for each display element and each disaster type.

Next, the operation of disaster display by the wide area fault display system will be described with reference to FIGS. 7 and 28 to 32.

FIG. 29 shows an operation flowchart of disaster display. When a failure occurs in the managed network,
Similar to the first embodiment, the display elements and display symbols on the system status display screen are changed from green to red (steps 201 and 202). Similar to the display screen of FIG. 7, the display screen has a disaster information menu 708 in the operation menu 707.
If you select 08, seismic intensity, precipitation, incident,
A type 3001 of disaster information such as an accident is displayed. The operator selects one piece of disaster information from the keyboard 16 or the mouse 17 to obtain the type of disaster information to be displayed (step 2901).

The signal processing unit 14 uses the disaster information input / output program 131 to acquire the disaster information acquisition table 120.
A communication medium and a disaster acquisition procedure for acquiring information on a designated disaster in a region corresponding to the display screen displayed on the display device 15 are searched based on the information, and the communication control unit 19 searches them.
