The present invention relates to a monitoring control device and an information communication device monitoring device used in a communication network conforming to (Synchronous Optical Network), and more particularly to improving a man-machine interface between the device and an operator.

[0002]

2. Description of the Related Art With the increasing demand for communication in recent years, the scale of information communication networks has been expanding. Recently, for example, existing networks of each country are connected to each other by ultra-high-speed international optical fiber cables to form a new large-scale network.

Generally, in a communication network, a network management system (Netw) is used for safe operation of the network, ensuring of security, and reduction of operation cost.
orkManagement System: NMS) is required. In the above-mentioned international network, for example, each country manages its own network (the device for performing the management is called a supervisory control device), and then the supervisory control device of each country is provided with a dedicated line (network management). A dedicated line) is used to jointly manage the entire network. A node such as a transmission device to be managed is called a monitored / controlled device.

Further, there is an information communication device monitoring device that manages not a whole network but individual transmission devices, for example. This type of device is realized, for example, by mounting a dedicated application on a portable terminal device (portable personal computer or the like), and is used by connecting to a slot of a transmission device via a cable. By taking this information communication device monitoring device to the place where the transmission device is installed, the state of the transmission device can be easily diagnosed.

By the way, the monitoring control device and the information communication device monitoring device (hereinafter referred to as a monitoring device for convenience) are
Operators with specialized skills (hereinafter referred to as operators)
Operated by. Based on the management information displayed on the monitor screen of the monitoring device, the operator can read the status of the monitored and controlled device, whether there is a failure, etc., and perform appropriate operations and processing through input devices such as the mouse, touch panel, and keyboard. To do.

Therefore, in order to reduce the burden on the operator and eliminate the risk of erroneous operation, it is necessary to consider the design of the information transmission means (man-machine interface) between the monitoring device and the operator. The conventional man-machine interface in this type of device will be described below.

First, in order to inform the operator of the presence / absence of a failure in the network, the following method has been conventionally used. That is, when the alarm information indicating the failure detection is displayed on the monitor screen, the display screen is divided into, for example, four stages, and the initial screen is changed to a more detailed screen.

As the above-mentioned four steps, (1) a screen which is summarized and displayed for each network system (initial screen) (2) the network system is divided into each monitored control device and a transmission line and displayed in network units Screen (3) screen displayed for each of a plurality of monitored control devices that make up the network (4) the monitored control device is divided and displayed for each shelf, and further displayed for each board that constitutes these shelves As a screen to be displayed, alarm information is hierarchized according to the unit (level) to be displayed.

By the way, in the above method, the method of selecting the display screen is such that the initial screen is sequentially followed by the target screen. In other words, from screen (1) to screen (2)
From the screen (2) to the screen (3) (or back), the screen which is one rank higher than the currently opened screen can be opened. Therefore,
In order for the operator to request the display of the screen (4), it is necessary to execute at least three operations from the initial screen, which is troublesome.

Further, in order to execute each operation, information communication must be performed between the monitored control device and the monitoring device, which increases the time and traffic, which causes some trouble.

Secondly, on the display screen, a plurality of objects such as a transmission device and a transmission path (both of which are monitored and controlled) are often displayed at the same time. At that time, it is convenient to be able to identify a specific device (for example, a device on which an operator is operating a terminal) from other devices on the screen. However, since the conventional monitor screen is displayed in monochrome and the display method is also based on symbolic expressions such as numbers, it is difficult to make the above identification.

Of course, the same can be said not only for devices such as transmission devices but also for transmission lines. In other words, there is a distinction between the active system and the standby system in the transmission path, whether each transmission path is normal, is in a faulty state, and the degree of failure is ... There is an object to be distinguished. Due to the same circumstances as described above, it has been difficult to make the distinction in the past and the operator was forced to bear an unnecessary burden.

[0013]

As described above, it must be said that the conventional monitoring control device and information communication device monitoring device lack the consideration of the man-machine interface. As a result, the operator is burdened and there is a risk of causing an erroneous operation. In addition to this, there was a heavy burden on the network, and there was a request to improve this.

The present invention has been made under the above circumstances.
It is an object of the present invention to provide a monitoring control device and an information communication device monitoring device that improve the man-machine interface, improve the operability and reduce the load on the network.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. (First Embodiment) FIG. 1 is a diagram showing a configuration of an information communication network according to an embodiment of the present invention. That is, in this embodiment, SDH (Synchronous Digital Hie)
It is assumed that the ring network conforms to rarchy), and m transmission devices N1 to Nm are high-speed lines (STM-1).
6 lines, etc.) are connected in a ring via FL.
Of the information transmitted through the high-speed line FL, information of an arbitrary channel is dropped on the low-speed line SL by the transmission devices N1 to Nm and sent to a communication device (not labeled) such as a multiplexer.

Here, the respective transmission devices N1 to Nm are connected to the supervisory control devices WS1 to WSm via LANs (Local Area Networks) L1 to Lm, respectively. These monitoring control devices WS1 to WSm are realized, for example, as general-purpose workstations, and any of the monitoring control devices WS1 to WSm can perform monitoring control on the transmission devices N1 to Nm. In addition, it is not necessary to make the number of the monitoring control devices WS1 to WSm correspond to the number of the transmission devices N1 to Nm in a one-to-one correspondence, and the number of installed devices may be determined according to the system request.

Transmission device monitoring terminals E1 to Em are connected to the transmission devices N1 to Nm as required. These transmission device monitoring terminals E1 to Em are intended to manage the transmission device of the connection partner and acquire information such as the operating state of the transmission device and the presence / absence of a failure, and the information is displayed to the operator (for example, monitor display). Notification).
The transmission device monitoring terminals E1 to Em are connected to the transmission devices N1 to N, respectively.
It is connected to the transmission device of the other party through a slot (not marked) provided in m.

FIG. 2 shows the configuration of the monitoring control devices WS1 to WSm. That is, the monitoring control devices WS1 to WSm are
An operation unit 1 including a mouse and a keyboard, a display unit 2 such as a display, an interface unit (I / F) 3 that realizes an interface function between a LAN and a transmission device to be connected, and a program related to monitoring control. A storage unit 4 that stores the above information, and a main control unit 5 that controls the operation unit 1, the display unit 2, and the interface unit (I / F) 3 based on a control program stored in the storage unit 4 are provided.

The storage unit 4 stores a monitored device selection table 4a in a predetermined storage area in addition to known contents such as the control program. FIG. 3 shows the contents of the monitored device selection table 4a. Before explaining this, each word in the figure will be described. First, the "station" means a station in which each of the monitoring control devices WS1 to WSm is installed. Further, the “monitored device” is, in a narrow sense, the transmission devices N1 to N1.
It means Nm. It should be noted that all monitored objects are included, such as a monitored device in a broad sense and units called so-called NEs (Network Element) such as power supplies and switching modules that configure the transmission devices N1 to Nm.

That is, the monitored device selection table 4a
Is the name of the station to be monitored on the network (in short, any information that can distinguish each station)
To the identification information (name or number) of the currently selected monitored device. For example, there are four stations A to D on the network, and each station has two monitored devices (for example, A1 and A2 at station A:
Other stations are also the same). It is assumed that the monitored device B2 in the B station has been selected by the operator's past operation. Of course, B1
However, the identification information of the monitored device selected at the closest time point to the present is written in the monitored device selection table 4a.

That is, the "currently selected monitored device" means "the monitored device that is selected (designated) in the past and that is selected at the time closest to the present time". To do. For a station that has not been selected in the past, an arbitrary monitored device may be set as a default and written in the monitored device selection table 4a.

On the other hand, the main control section 5 is realized as, for example, a microcomputer or the like, and includes the transmission devices N1 to N1.
In addition to known control means such as functions related to information communication with Nm and functions related to acquisition and processing of management information, display control means 5a is provided.

The display control means 5a obtains the management information (and the information obtained by processing this management information).
To control the display method when displaying on the display unit 2 to realize a user-friendly man-machine interface. That is, in order to make it possible to visually distinguish what is to be distinguished from the others, such as the monitored device in a failure state, the transmission line, and the active / standby system of the transmission line, It controls the way.

The display control means 5a is realized, for example, as software executed based on the procedure stored in the storage unit 4, and its detailed processing procedure is shown in the flowcharts of FIGS. 4 and 5. .

Since the configuration of each of the transmission devices N1 to Nm is not deeply related to the idea of the present invention,
The description is omitted in this embodiment. The configuration of the transmission device monitoring terminals E1 to Em will be described in (Third Embodiment).

Next, with reference to the flowcharts of FIGS. 4 and 5 and FIGS. 6 to 8, the operation of the supervisory control devices WS1 to WSm configured as described above will be described. In the following description, the monitoring control device WS1 is mainly described, but the same applies to the other monitoring control devices WS2 to WSm.

FIG. 4 shows a processing procedure in the main control section 5 of the supervisory control device WS1 having the above configuration. In the following description, “monitored device” is synonymous with “transmission device”.
Further, “alarm information” means “management information”, and “summary” is almost synonymous with “summary”.

In FIG. 4, the main control unit 5 reads alarm information from the monitored devices (transmission devices N1 to Nm) on the network, performs predetermined processing (known) based on the acquired alarm information, and summarizes the information. Is displayed on the initial screen (step S41). An example of the initial screen is shown in FIG.

On the initial screen (Display-a) of FIG. 6, the stations A to D are displayed as circles at corresponding positions on a simple map of Japan, and the transmission lines connecting these stations are shown by thick lines. ing. The screens shown in FIGS. 6 to 8 are all displayed on the display unit 2, and a display object can be designated by a pointing device such as a mouse. Such a GUI (Graphical User Interfac
An OS (Operation System) having e) is well known.

On the initial screen of FIG. 6, for example, station A
Is specified (for example, by clicking the right button of the mouse), the monitored device selection window 100 for the station A is opened. In this window,
Information indicating which station is designated (Station:
A) and the identification information (1,
2) is shown. A network monitoring screen display button 200 is displayed on this initial screen, and clicking this button opens the next screen.

The details of the processing in step S41 are as follows. That is, when a failure or a warning occurs in any monitored device on the network, the monitored device that has generated the failure / warning autonomously notifies the monitoring control devices WS1 to WSm of the alarm information. The monitoring control device WS1 (main control unit 5) that has received the notification of the alarm information reads the occurrence time of the failure / alarm, the occurrence location, the cause, the importance, etc. from the alarm information. Then, the main control unit 5 graphically displays the station or the transmission line which is the source of the fault / alarm on the initial screen of FIG. 6 according to the importance of the alarm.

Here, in order to distinguish the station or the transmission line which is the source of the trouble / alarm from the others, the thickness of the line may be changed, the line may be made to blink, or a halftone display may be made. It may be displayed in a different color. Also, changing the line thickness can be used to distinguish the active system / standby system of the transmission line.

The alarm information can be acquired not only by passively receiving the alarm information sent from the monitored device which is the source of the failure but also more actively, for example, periodically with respect to each monitored device. A request message may be sent to forcefully send the alarm information. In short, the acquisition timing of the alarm information is arbitrary, and the display content changes accordingly. Further, when the monitor control device starts up, the alarm occurrence state may be sent to all monitored devices connected to the network, and the alarm occurrence state may be read and displayed on the initial screen. By referring to the initial screen displayed in this manner, the maintenance person confirms the place where the alarm has occurred and the importance thereof, and then performs a predetermined operation. In this embodiment, it is assumed that there are three options, and these operations will be referred to as operation OP1, operation OP2, and operation OP3.

Operation OP1 to operation O
The specific operation contents of P3 are as follows. That is, in operation OP1, the operator clicks the network monitoring screen display button 200 on the initial screen (FIG. 6) with the mouse (either the left or right button). In operation OP2, the operator clicks an arbitrary station (A to D) on the initial screen with the right button of the mouse.
In operation OP3, the operator clicks an arbitrary station building (A to D) on the initial screen with the left mouse button.

Now, in FIG. 4, operation OP1
When is executed, the main control unit 5 displays the network monitoring screen (Display-b) shown in FIG. 7 on the display unit 2 (step S42). On this network monitoring screen, monitored devices (A1, A2,
B1, B2, C1, C2, D1, D2) and the transmission path connecting these monitored devices are displayed in a more abstract form. The symbols A to D are not displayed on the screen. Also on this network monitoring screen, alarm information is graphically displayed according to its importance, as in the initial screen. Here, it is assumed that a failure has occurred in the monitored device A1.

Next, the main control section 5 waits for the operator's operation, and when an arbitrary monitored device displayed on the network monitoring screen is clicked (designated) by the mouse, an instruction to call the monitored device display screen is issued. Detect (step S4
3). In response to this, the main control unit 5 updates the item of the monitored device in the monitored device selection table 4a shown in FIG. 3 to the specified monitored device (step S44).

Then, the main control section 5 graphically displays the alarm information relating to the designated monitored device on the monitored device display screen (Display-c) shown in FIG. 8 (step S45).

The monitored device display screen shown in FIG. 8 displays the location of the alarm for each board accommodated in the monitored device. Here, Equipmen
The name of the monitored device that is the source of the alarm is also displayed as t: A1.

Next, in FIG. 4, operation OP2
The processing procedure when is executed will be described. When, for example, the station A is clicked with the right mouse button on the initial screen, the main control unit 5 opens the monitored device selection window 100 on the initial screen for the designated station (station A). (Step S46).

This monitored device selection window 100 is
Although the description is duplicated, it is a window for exclusively selecting the monitored device for which the monitored device display screen is to be displayed from the plurality of monitored devices installed in each station.

Next, the main control unit 5 waits for the operator's operation, and clicks (specifies) one of the monitored devices displayed in the monitored device selection window 100 with the mouse.
Then, the calling instruction of the monitored device display screen is detected (step S47). From this, the main control unit 5 performs step S
Then, the procedure proceeds to 44 and the same procedure as described above is executed (steps S44 and S45). With this procedure, the network monitoring screen is skipped in operation OP2.

Next, referring to FIG. 4, the operation OP3 is performed.
The processing procedure when is executed will be described. When, for example, the station A is clicked with the left mouse button on the initial screen, the main control unit 5 detects an instruction to call the monitored device display screen at this stage (step S48), and then step S45. Jump to and monitor the device display screen (Fig. 8)
Is displayed.

In order to display the monitored device display screen, it is necessary to determine which monitored device in the designated station is to be displayed. This determination is made by referring to the monitored device selection table 4a in the storage unit 4. That is, in the monitored device selection table 4a, the monitored device designated at the closest time point in the past is described (for each station). Therefore, by reading the monitored device described in the monitored device selection table 4a, the previously selected monitored device is selected again and displayed on the monitored device display screen. By such a procedure, in operation OP3, it is possible to jump directly from the initial screen to the monitored device display screen.

The manner of display on the display unit 2 in each operation is summarized as follows. OP1… Initial screen → Network monitoring screen → Monitored device display screen OP2… Initial screen → Monitored device selection window 100 →
Monitored device display screen OP3 ... Initial screen → Monitored device display screen Next, the operation procedure of the operator in the present embodiment will be described.
This will be described with reference to FIG. The operator performs one of the operations with reference to the initial screen displayed in step S51. The operation contents in each operation have already been described (steps S52, S56, S5).
9).

When the operator executes the operation OP1 (step S52), the alarm information is displayed on the network monitoring screen (step S53), and the operator receives it and clicks an arbitrary monitored device (step S54). Then, the alarm occurrence state of the designated monitored device is displayed on the monitored device display screen (step S55).

When the operator executes operation OP2 (step S56), the monitored device selection window 100 of the designated station is opened (step S5).
7). In response to this, the operator clicks (exclusively) one monitored device (step S58). Then, in step S55, the alarm occurrence state of the designated monitored device is displayed on the monitored device display screen.

When the operator executes the operation OP3 (step S59), the operation jumps to step S55, and the alarm generation state regarding the monitored device designated last time (for each station) is displayed on the monitored device display screen.

As described above, in this embodiment, the display control means 5a is provided in each of the monitoring control devices WS1 to WSm.
Then, the alarm source on the display unit 2 is displayed in a form distinguishing it from other sources. In addition, by designating an arbitrary station on the initial screen of the display unit 2, a monitored device selection window 100 in which a monitored device installed in the station can be selected is opened. I am able to jump. Further, the monitored unit selection table 4a is stored in the storage unit 4, and the monitored unit selection table 4a is stored.
It is possible to jump directly from the initial screen to the monitored device display screen based on the information of which monitored device was selected last time obtained by referring to.

Therefore, it becomes easier to visually recognize more detailed alarm information such as the place where the alarm is generated, its importance, or the cause of the alarm, which reduces the burden on the operator and reduces the risk of erroneous operation. In addition, it is possible to give a range of selection to the operation from the initial screen to the target monitored device display screen, and it is possible to perform the operation according to the judgment and selection of the maintenance person. further,
Since it is possible to jump from the initial screen to the target monitored device display screen at once, it saves time and reduces communication traffic between the monitoring control device and the monitored device. Become.

From the above, the man-machine interface can be improved, the operability can be improved, and the load on the network can be reduced.

(Modification of the First Embodiment) Here, a modification of the present embodiment will be described with reference to FIG. Figure 9
Is the network monitoring screen (Display) shown in FIG.
It is a modification of y-b). The network monitoring screen in this modification is more abstract than that of FIG. 7, each station A to D is displayed as one square, and the transmission path is also represented by one line. There is. That is, it can be considered that the initial screen is more abstracted.

On this screen, when the station A (the object indicating the station) is clicked, the monitored device selection window 300 is opened. This monitored device selection window 30
0 also characterizes this modified example, and the number of buttons (n in this case, n) corresponds to the number of monitored devices installed in each station.
This is what is displayed. Then, by designating the monitored device of the station with an arbitrary button in this window, it is possible to reach the monitored device display screen for the monitored device.

By doing so, even when the number of monitored devices installed in the station building increases, it is possible to realize an easy-to-see display without making the screen display unnecessarily complicated. Particularly in recent years, STM-64 (10 Gb
Studies on ultra-high-speed transmission such as ps class) have begun. To achieve this, for the time being, it is considered to increase the number of transmission devices installed in the station building while using wavelength multiplexing technology, etc. Can greatly contribute to The monitored device selection window 300
May be displayed on the initial screen.

(Second Embodiment) Next, the second embodiment of the present invention will be described.
An embodiment will be described. In the following drawings, the same parts as those already described are designated by the same reference numerals, and only the parts different from the above will be described.

FIG. 10 is a diagram showing the configuration of the monitoring control devices WS1 to WSm according to this embodiment. That is, the monitoring control devices WS1 to WSm shown in FIG. 10 have almost the same configuration as that of FIG. 2, but the configuration of the main control unit is different. For the sake of distinction, the reference numeral 6 is attached. That is, the main control unit 6 includes a display color designation control unit 6a in addition to the control function of the main control unit 5.

In this embodiment, the station or transmission line that is the source of the fault / alarm is displayed in a color different from the others to distinguish them. This operation is performed by the display control means 5
brought by a.

The display color designation control means 6a controls the operator to designate the color of the object displayed on the display section 2. That is, the display color designation control means 6a
A display color setting window as shown in FIG. 11 is opened on the screen in response to the operator's request.

In this window, (Display C
(control) is given, (Color),
There are three items, (Date Type) and (Sorting). First, in (Color), (Criti
cal), (Major), ..., (Maintenan
There are seven sub-items (ce), which represent the status of the fault. Of these, the top (Critica
l) indicates that it is the most serious (fatal) disorder,
The degree of lethality decreases as you go down. On the right side of each small item, a current display color is shown on the left side and a new setting color is shown on the right side with a (Color) button interposed therebetween. And by clicking the Color button,
A color palette (not shown) is displayed so that any color can be selected. As an example of the setting of the display color, the most fatal (Critical) may be set to, for example, red, and as the degree of fatality decreases, it may be set to brown, amber, ...

Next, in (Date Type), the method of displaying the date is set. Here, the date display is to display the date and time when the failure / alarm has occurred on each screen, which itself is existing, and is performed by the control of the main control unit 5, for example. This is convenient because the date and time when the failure / alarm occurred can be seen at a glance.

For this item, (Order), (Type
e) There is a small item. In (Order), "time"
Set whether to display in "Date" order or "Date""Time" order. In (Type), MM is the month, D
D means day, YYYY means year, and here MM / D
Since D / YYYY is specified, the display will be in the form of month / day / year. This may be set according to the preference of the operator according to the customs of each country.

Finally, in (Sorting), the display order (stacking method) of the arrived data is designated. That is, it specifies whether the latest data is at the top or the bottom.

Here, what characterizes the present embodiment is the (Color) item, and by providing this (the display color designation control means 6a is provided so that the above window is displayed and the operator's setting is accepted. By doing so, it becomes possible for the operator to preset the importance according to the alarm type and the display color for identifying it.

FIG. 12 shows an example of a screen in which colors are designated in this way. FIG. 12 corresponds to the network monitoring screen (FIG. 7) in the first embodiment. First, the active / standby system of the transmission line is distinguished by thick / thin lines. This is due to the operation of the display control means 5a.

Similarly, each of the monitored devices (here, numbers # 0 to # 3 are assigned) by the display control means 5a.
And the transmission lines are displayed in different colors. Here, red indicates a fault state, green indicates a non-fault (steady state), and gray indicates a non-operating state.

As described above, it becomes possible to grasp the state of the monitoring target more finely by vivid color coding. In particular, the state of the transmission line (active system, standby system, steady state, fault state, and the degree of the fault, etc.) can be grasped at a glance, which is a great advantage for the operator. Further, the display color can be freely set, which is convenient.

(Third Embodiment) Next, the third embodiment of the present invention will be described.
An embodiment will be described. In the following drawings, parts common to those in the already described figures are designated by the same reference numerals, and only the parts different from the above will be described here.

FIG. 13 is a diagram showing the configuration of the transmission device monitoring terminals E1 to Em according to this embodiment. Each of the transmission device monitoring terminals E1 to Em has an operation unit 7 including a mouse and a keyboard, a display unit 8 such as a display, and an interface unit (I / F) 9 that realizes an interface function between the transmission device and the connected transmission device. And a storage unit 10 that stores programs related to monitoring and control of the transmission device, these operation unit 7, display unit 8, interface unit (I / F)
And a control unit 11 for controlling 9 based on a control program stored in the storage unit 10.

By the way, the control unit 11 uses the position recognition means 1
1a and display control means 11b. The position recognizing means 11a recognizes which of the transmission devices N1 to Nm in the network the terminal is connected to. In other words, it recognizes at which position in the network the transmission device to which the own terminal is connected is located. The position recognition means 1
1a itself is already known, and the processing procedure at the time of position recognition is already known, so a detailed description is omitted here.

What characterizes this embodiment is the display control means 11b. The display control means 11b controls the manner of displaying the screen of the display unit 8 and realizes a user-friendly man-machine interface. That is, no matter which transmission device the own terminal is connected to,
The transmission device to which the own terminal is connected is displayed on the screen in such a manner that it can be distinguished from others. The position recognition means 1
The display control unit 11b and the display control unit 11b are implemented as software executed based on the procedure stored in the storage unit 10.

In the present embodiment, a greater effect can be obtained when the network configuration is complicated.
FIG. 14 shows an example of a slightly complicated network configuration. In this example, three ring network systems are connected to each other. In the figure, a square indicates a transmission device, and a line indicates a transmission line. By the way, in SDH, the maximum number of transmission devices that can be accommodated in one ring network system is
It is 16 pieces.

FIG. 15 shows an example of the screen of the display unit 8 in the transmission device monitoring terminals E1 to Em of this embodiment. Here, a transmission device monitoring terminal connected to the transmission device indicated by # 6 in FIG. 15 (probably a transmission device monitoring terminal E6)
Shows the screen in. In FIG. 15, first, the transmission paths are the active system (Service solid line) and the standby system (Protection:
(Dotted line). Then, the transmission device indicated by # 6 is distinguished from the others and is displayed so as to be surrounded by a thick frame.

By doing so, the operator of the transmission device monitoring terminal E6 can distinguish the own station node at a glance. The advantage of this becomes even more apparent when the number of transmission devices displayed on the screen is large. For example, when an operator having a transmission device monitoring terminal frequently moves between different stations, the current station can be identified at a glance at the destination station. For this reason, the risk of erroneous operations such as accidentally clicking after clicking on a familiar place is greatly reduced. Also, the time required for the operation can be shortened.

The present invention is not limited to the above embodiments. For example, operations OP2 and O
The correspondence between P3 and the right and left of the mouse button can be set arbitrarily. Further, each operation may be executed by other operation means.
