Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to, for example, SDH (Syn
chronous Digital Hierarchy) standard or SONET
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 improvement of a man-machine interface between the device and an operator.

[0002]

2. Description of the Related Art With the recent increase in communication demand, the scale of information communication networks has been steadily expanding. In recent years, for example, existing networks in each country have been interconnected by an ultra-high-speed international optical fiber cable to form a new large-scale network.

[0003] In general, in a communication network, a network management system (Netw) is used in order to secure the operation of the network, secure security, and reduce operation costs.
It is necessary to provide an orkManagement System (NMS). In the international network as described above, for example, a unique network for each country is managed in each country (a device for performing management is called a supervisory control device), and then the supervisory control device for each country is connected to a dedicated line (network management). (Dedicated line) and jointly manage the entire network. Note that a node such as a transmission device to be managed is called a monitored control device.

Further, there is an information communication device monitoring device that manages, for example, individual transmission devices, not the entire network. This type of device is realized by mounting a dedicated application on, for example, a portable terminal device (portable personal computer or the like), and is used by being connected to a slot of a transmission device via a cable. By bringing the information communication device monitoring device to the installation location of the transmission device, the state of the transmission device can be easily diagnosed.

By the way, the above monitoring control device and information communication device monitoring device (hereinafter referred to as monitoring device for convenience) are:
Operators with specialized skills (hereinafter referred to as operators)
Is operated by The operator reads the status of the monitored control device, whether there is a failure, etc. based on the management information displayed on the monitor screen of the monitoring device, and performs appropriate operations and processing via input devices such as a mouse, touch panel, and keyboard. 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 information transmission means (man-machine interface) between the monitoring device and the operator. Hereinafter, a conventional man-machine interface in this type of device will be described.

First, the following method has conventionally been used to notify the operator of the presence or absence of a failure in the network. That is, when displaying the alarm information indicating the failure detection on the monitor screen, the display screen is divided into four stages, for example, and a transition is made from the initial screen to a more detailed screen.

[0008] The above four stages are as follows: (1) a screen for summarizing and displaying in network system units (initial screen) (2) a network system is divided into each monitored control device and a transmission path and displayed in network units (3) Screen to be displayed for each of a plurality of monitored control devices constituting the network (4) Display of each of the monitored control devices divided for each shelf (shelf), and further, for each board constituting these shelves A screen that provides alarm information hierarchically according to the display unit (level) is provided.

By the way, in the above-mentioned method, the method of selecting a display screen is a method of sequentially tracing from an initial screen to a target screen. That is, from the screen (1), the screen (2)
From the screen (2) to the screen (3) (or back), only the screen 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.

In order to execute each operation, information must be communicated between the monitored control device and the monitoring device, so that the time and traffic increase, which is inconvenient.

Second, on the display screen, a plurality of objects such as a transmission device and a transmission line (both of which are monitored and controlled) are often displayed simultaneously. At this time, it is more convenient to be able to identify a specific device (for example, a device on which an operator is operating a terminal) and other devices on a screen. However, since the conventional monitor screen is a monochrome display, and the display method is a symbolic expression such as a number, it is difficult to perform the above identification.

Of course, the same can be said not only for a device such as a transmission device, but also for a transmission path. In other words, the transmission path has a distinction between the working system and the protection system, and whether each transmission path is normal, is in a failure state, and the degree of the failure is... There are objects to be distinguished. Conventionally, it is difficult to discriminate between the above, and the operator is imposed an unnecessary burden.

[0013]

As described above, the conventional monitoring control device and information communication device monitoring device have to be said to lack consideration for the man-machine interface. This places a burden on the operator and may cause an erroneous operation. In addition to this, the burden on the network was heavy, and there were requests to improve this.

The present invention has been made in view of 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 a man-machine interface, improve operability, and reduce a burden on a network.

[0015]

In order to achieve the above object, a monitoring and control apparatus according to the present invention collects information for network management from a monitoring target existing in an information communication network, and also collects the collected information. In a monitoring and control device having a function of visually displaying the state of the information communication network on a display device, when performing display on the display device,
It is characterized by comprising display control means for displaying monitoring targets having different attributes from each other in a distinguished manner.

By adopting such means, different names should be assigned to, for example, a plurality of offices, for example, monitoring targets such as offices, transmission devices, and transmission lines. Therefore, these are displayed on the display in a form in which they are distinguished according to the difference in the attributes.
The method of distinction is not only the name, but also the format, operation status,
What is necessary is just to determine according to the attribute which should be distinguished from others, such as positioning in a network.

The transmission line (communication line) is roughly classified into an active system and a standby system, but these may be displayed separately.

As a method of distinction, the type of drawing line (dotted line, solid line, etc.) and its thickness may be changed, may be blinked, may be displayed in a shaded manner, or the color may be changed. It may be displayed differently from others.

Further, in the monitoring control apparatus according to the present invention, the display control means may be provided on the display unit at a first screen showing at least a connection state between stations in the information communication network, and at each of the stations. A second screen for selecting and specifying the monitored device and a third screen showing the specified monitored device divided into its minimum monitoring units are hierarchically displayed according to a user operation. It is characterized by doing.

Further, when any of the stations shown on the first screen is selectively designated, the display control means selects and designates a monitored device installed in the station. Window is opened on the first screen, and when any one of the monitored devices is selectively designated in the monitored device selection window, the third monitored device corresponding to the monitored device is selected. Is displayed.

In this way, even if the number of monitored devices increases, the display for designating the monitored device can be displayed simply and completely in the form of a window, which is convenient without complicating the screen display. .

The monitoring control apparatus according to the present invention further comprises storage means for storing an updatable monitored device selection table in which the monitored device selected last time is associated with each station, and the display control means comprises: When any one of the stations shown on the first screen is selectively designated, the third device for the previously selected monitored device in the station is referred to by referring to the monitored device selection table. Is displayed.

By doing so, it is possible to jump from the first screen to the third screen, so that the trouble of the user (operator) can be saved, and the communication between the monitoring control device and the monitored device can be avoided. Can reduce the number of messages transmitted and received, and as a result, the burden on the network can be reduced.

The information communication device monitoring device of the present invention is used by being connected to an information communication device existing in an information communication network, and is connected to at least one of the information communication network and an information communication device that is a connection partner. In the information communication device monitoring device that collects information for managing the information communication device, and performs monitoring control of the connected information communication device based on the collected information, A display for displaying at least a first screen showing at least a state of connection between stations, and a form on the first screen in which a station to which the connected information communication device belongs is distinguished from other stations. It is characterized by comprising a display control means for displaying by.

Thus, the operator handling the information communication device monitoring device recognizes at a glance the position of the currently connected monitored device in the network (that is, the position of the current location (station)) on the display screen. it can. Also in this manner, a user-friendly man-machine interface that eliminates the risk of erroneous operation can be realized as described above.

Further, the monitoring control device and the information communication device monitoring device of the present invention allow the display color of the display object on the screen of the display unit to be set according to a user's request,
The display control means further comprises a display color designation control means for displaying each of the display objects in the set display color.

By doing so, the display color of the screen can be freely set, which is convenient for operation.

In the claims and the description of the invention, "screen" does not mean a display device (such as a cathode ray tube or a liquid crystal display) in a display device. In each of the above sections, the term “screen” is used to mean a visually displayed symbol, picture, pattern, or the like.

[0029]

Embodiments of the present invention will be described below 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 the present embodiment, the SDH (Synchronous Digital Hie
(Rarchy), and m transmission devices N1 to Nm are connected to a high-speed line (STM-1).
(E.g., 6 lines) are connected in a ring via FL.
Of the information transmitted on 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 transmission devices N1 to Nm are connected to the monitoring 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 can perform monitoring control on each of the transmission devices N1 to Nm from any of the monitoring control devices WS1 to WSm. 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 on a one-to-one basis, and the number of the installation devices may be determined according to the requirements of the system.

Further, transmission device monitoring terminals E1 to Em are connected to the transmission devices N1 to Nm as required. The transmission device monitoring terminals E1 to Em target the transmission device of the connection partner as a management target, acquire information such as the operating state of the transmission device and the presence or absence of a failure, and provide the information to the operator (for example, monitor display). Notice).
Each of the transmission device monitoring terminals E1 to Em is connected to each of the transmission devices N1 to N
m is connected to the transmission device of the other party through a slot (not labeled) provided in m.

FIG. 2 shows the configuration of the monitoring and 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 for realizing an interface function between a connected LAN and a transmission device, and a program related to monitoring control 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.

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 describing this, each word in the figure will be described. First, “station” means a station in which each of the monitoring control devices WS1 to WSm is installed. In addition, the "monitored device" is narrowly defined here as the transmission device N1.
Nm. In short, all objects to be monitored are included, such as a device to be monitored in a broad sense, and a unit called a so-called NE (Network Element) such as a power supply or a switching module constituting each of the transmission devices N1 to Nm.

That is, the monitored device selection table 4a
Is the name of the station to be monitored that exists on the network (in short, any information can be used as long as each station can be distinguished)
Is associated with identification information (such as a name or a 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 in the A station:
Other stations are the same). It is assumed that, for example, in the station B, the monitored device B2 has been selected by the operator in the past. Of course, B1
May be selected, the identification information of the monitored device selected most recently at this time is written in the monitored device selection table 4a.

That is, the “currently selected monitored device” means “the monitored device that has been selected (designated) in the past and has been selected closest to the present time”. I do. For stations that have not been selected in the past, an arbitrary monitored device may be set by default and written in the monitored device selection table 4a.

On the other hand, the main control unit 5 is realized as, for example, a microcomputer or the like.
A display control unit 5a is provided in addition to known control units such as a function relating to information communication with Nm and a function relating to acquisition and processing of management information.

The display control means 5a controls the acquired management information (and information obtained by processing the management information).
Is displayed on the display unit 2 to realize a user-friendly man-machine interface. That is, the display on the display unit 2 is made so that it is possible to visually distinguish what is to be distinguished from others, such as a monitored device or a transmission line in a failure state, or an 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 section 4, and the detailed processing procedure is shown in the flowcharts of FIGS. .

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

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

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

In FIG. 4, the main control unit 5 reads alarm information from 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). FIG. 6 shows an example of the initial screen.

In the initial screen (Display-a) of FIG. 6, each of the office buildings A to D is displayed at a corresponding position on a simple map of Japan by circles, and the transmission lines connecting these offices are indicated by thick lines. ing. Note that the screens shown in FIGS. 6 to 8 are all displayed on the display unit 2 and can specify a display object using a pointing device such as a mouse. Such a GUI (Graphical User Interface)
An OS (Operation System) having e) is well known.

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

The processing in step S41 is as follows in more detail. That is, when a failure or an alarm occurs in any of the monitored devices on the network, the monitored device that has generated the failure / alarm autonomously notifies the monitoring control devices WS1 to WSm of the alarm information. Upon receiving the notification of the alarm information, the monitoring control apparatus WS1 (main control unit 5) reads the time, location, factor, importance, and the like of the occurrence of the fault / alarm from the alarm information. Then, the main control unit 5 graphically displays the station or the transmission path that 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 a station or a transmission line from which a trouble or an alarm is generated from other stations, the thickness of the line may be changed, the line may be blinked, or a shaded display may be used. It may be good, or the color may be changed and displayed. Changing the line thickness can also be used to distinguish between the active system and the standby system of the transmission path.

The method of acquiring the alarm information is not only passively receiving the alarm information sent from the monitored device at the failure source, but also more actively, for example, periodically, for each monitored device. A request message may be sent to force the alarm information to be sent. In short, the acquisition timing of the alarm information is arbitrary, and the display content changes accordingly. Further, when the monitoring control device starts up, an alarm occurrence state may be transmitted to all monitored devices connected to the network, and this may be read out and displayed on the initial screen. With reference to the initial screen displayed in this manner, the maintenance person confirms the location and importance of the alarm, and then performs a predetermined operation. In the present 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 button or the right button). In operation OP2, the operator clicks an arbitrary station (A to D) on the initial screen with the right mouse button.
In operation OP3, the operator clicks an arbitrary station (A to D) on the initial screen with the left mouse button.

The operation OP1 in FIG.
Is executed, the main control unit 5 causes the display unit 2 to display a network monitoring screen (Display-b) shown in FIG. 7 (Step S42). On this network monitoring screen, the monitored devices (A1, A2,
B1, B2, C1, C2, D1, D2) and the transmission lines 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, similar to the initial screen, alarm information is displayed graphically according to its importance. Here, it is assumed that a failure has occurred in the monitored device A1.

Next, the main controller 5 waits for the operation of the operator, and when any monitored device displayed on the network monitoring screen is clicked (designated) with a mouse, the main controller 5 issues a call instruction of the monitored device display screen. Detect (Step S4)
3). In response, 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 alarm information relating to the specified 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 an alarm occurrence location for each board accommodated in the monitored device. Here, Equipment
The name of the monitored device that caused the alarm is also displayed as t: A1.

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

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

Next, the main control unit 5 waits for the operation of the operator, and clicks (designates) any one of the monitored devices displayed in the monitored device selection window 100 with the mouse.
Then, a call instruction on the monitored device display screen is detected (step S47). Thus, the main control unit 5 proceeds to step S
The process proceeds to 44, and the same procedure as above is executed (steps S44 and S45). According to such a procedure, the network monitoring screen is skipped in operation OP2.

Next, in FIG.
The processing procedure in the case where is executed will be described. When, for example, the station building A is clicked on the initial screen with the left button of the mouse, the main control unit 5 detects a call instruction of the monitored device display screen at this stage (step S48), and then proceeds to step S45. Jump to and display the monitored device display screen (Fig. 8)
Is displayed.

Now, 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 of the storage unit 4. That is, the monitored device selection table 4a describes the monitored device specified at the closest point in the past (for each station). Thus, 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. According to such a procedure, in operation OP3, it is possible to jump from the initial screen directly to the monitored device display screen.

The way of displaying 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 according to the present embodiment will be described.
This will be described with reference to FIG. The operator performs any operation 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), alarm information is displayed on the network monitoring screen (step S53), and in response to this, the operator clicks on any monitored device (step S54). Then, the alarm occurrence state of the specified monitored device is displayed on the monitored device display screen (step S55).

When the operator executes operation OP2 (step S56), a 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, the process proceeds to step S55, and the alarm occurrence state of the specified monitored device is displayed on the monitored device display screen.

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

As described above, in the present 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 manner distinguished from the others. Also, by specifying 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, and a monitored device control screen is displayed from here. I can jump. Further, a monitored device selection table 4a is stored in the storage unit 4, and the monitored device selection table 4a is stored.
, The user can jump directly from the initial screen to the monitored device display screen based on information on which monitored device was selected last time.

Therefore, it is easy to visually recognize more detailed alarm information such as the place where the alarm is generated, its importance, and the cause of the alarm, so that the burden on the operator is reduced and the possibility of erroneous operation is reduced. In addition, the operation from the initial screen to the target monitored device display screen can be provided with a range of selection, and the operation according to the judgment and selection of the maintenance person can be performed. further,
Since it is possible to jump from the initial screen to the target monitored device display screen at a stretch, it is not necessary to save time and reduce the communication traffic between the monitoring control device and the monitored device. Become.

As described above, the man-machine interface is improved, the operability can be improved, and the burden on the network can be reduced.

(Modification of First Embodiment) Here, a modification of the present embodiment will be described with reference to FIG. FIG.
Is a network monitoring screen (Display) shown in FIG.
yb). The network monitoring screen in this modified example is more abstracted than that of FIG. 7, and each of the office buildings A to D is displayed by one square, and the transmission path is also represented by one line. I have. That is, it can be considered that the initial screen is more abstracted.

On this screen, when the user clicks on the station A (object indicating), a monitored device selection window 300 is opened. This monitored device selection window 30
0 also characterizes this modification, and the number of buttons (here, n) corresponds to the number of monitored devices installed in each station.
) Are displayed. Then, by specifying the monitored device of the station with an arbitrary button in this window, the monitored device display screen for the monitored device can be reached.

In this way, even when the number of monitored devices installed in the station building increases, it is possible to realize an easy-to-view display without making the screen display unnecessarily complicated. Particularly in recent years, STM-64 (10 Gb
(ps class) has been studied. In order to realize this, it is considered to increase the number of transmission devices installed in the station building while using wavelength multiplexing technology etc. for the time being, so even in such a case, improve the man-machine interface Can be greatly contributed to. The monitored device selection window 300
May be displayed on the initial screen.

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

FIG. 10 is a diagram showing a configuration of the monitoring and controlling devices WS1 to WSm according to the present embodiment. That is, the monitoring control devices WS1 to WSm shown in FIG. 10 have substantially the same configuration as that of FIG. 2, but differ in the configuration of the main control unit. The reference numeral 6 is attached for distinction. That is, the main control unit 6 includes a display color designation control unit 6a in addition to the control functions of the main control unit 5.

In this embodiment, the station or the transmission line that is the source of the fault / alarm is distinguished by displaying it in a different color from the others. This operation is performed by the display control unit 5.
a.

The display color designation control means 6a controls the operator to designate the color of the object displayed on the display unit 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 an operator request.

In this window, (Display C
(Color), (Color),
There are three items: (Date Type) and (Sorting). First, (Color) contains (Criti
cal), (Major), ..., (Maintenan
ce), there are seven sub-items, which represent fault conditions. Among them, the top row (Critica
l) is the most serious (fatal) disorder,
The degree of criticality decreases as going down. On the right side of each sub-item, the current display color is shown on the left side of the (Color) button, and the new set color is shown on the right side. And by clicking the Color button,
A color palette (not shown) is displayed, and an arbitrary color can be selected. As a setting example of the display color, the most critical (Critical) may be set to, for example, red, and brown, amber,..., Gray, and green may be set as the degree of the criticality decreases.

Next, in (Date Type), a method of displaying a date is set. Here, the date display is to display the date and time when the trouble / alarm occurred on each screen, and this is already existing, and is performed under 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 known at a glance.

The items include (Order), (Type
e) There is a small item. (Order)
Set whether to display in the order of "date" or "date" and "time". (Type), MM is month, D
D means day, YYYY means year, here MM / D
Since D / YYYY is specified, display is made in the form of month / day / year. This may be set in accordance with the custom of each country and according to the preference of the operator.

Finally, in (Sorting), the display order of the arriving data (how to stack) is specified. In other words, it specifies whether the latest data is at the top or bottom.

Here, what characterizes the present embodiment is a (Color) item. By providing this item, a (display color designation control means 6a is provided so that the window is displayed to accept operator settings. By doing so, it becomes possible for the operator to set in advance the importance according to the alarm type, the display color for identifying the importance, and the like.

FIG. 12 shows an example of a screen on 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 path 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, the numbers # 0 to # 3 are assigned) by the display control means 5a.
And the transmission path are displayed in different colors. Here, red indicates a failure state, green indicates a non-failure (steady state) state, and gray indicates a non-operation state.

With the above, the state of the monitoring target can be grasped more finely by vivid color coding. In particular, since the state of the transmission path (working system, standby system, steady state, failure state, and the degree of the failure, etc.) can be grasped at a glance, the advantage for the operator is great. Further, the display color can be freely set, which is convenient.

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

FIG. 13 is a diagram showing a configuration of the transmission apparatus monitoring terminals E1 to Em according to the present embodiment. The transmission device monitoring terminals E1 to Em include 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 implements an interface function between the transmission device and a connected transmission device. And a storage unit 10 storing programs related to monitoring and control of the transmission device, and an operation unit 7, a display unit 8, and an interface unit (I / F).
And a control unit 11 for controlling the control unit 9 based on a control program stored in the storage unit 10.

By the way, the control unit 11 controls the position recognizing means 1
1a and display control means 11b. Among these, 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 where in the network the transmission device to which the terminal of interest is connected is located. This position recognition means 1
Since 1a itself is known and the processing procedure at the time of position recognition is already known, detailed description thereof is omitted here.

What characterizes the present 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. In other words, no matter which transmission device your terminal is connected to,
The transmission device to which the terminal is connected is displayed on the screen in a form that can be distinguished from the others. Note that the position recognition means 1
1a, the display control unit 11b is realized as software or the like 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 somewhat 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 path. Incidentally, in SDH, the maximum number of transmission devices that can be accommodated in one ring network system is:
There are 16.

FIG. 15 shows an example of the screen of the display unit 8 in the transmission apparatus monitoring terminals E1 to Em of the present embodiment. Here, the transmission apparatus monitoring terminal connected to the transmission apparatus indicated by # 6 in FIG. 15 (tentatively, transmission apparatus monitoring terminal E6)
3 shows a screen. In FIG. 15, first, the transmission path is a working system (Service solid line) and a protection system (Protection:
(Dotted line). Then, the transmission device indicated by # 6 is distinguished from the others and displayed so as to be surrounded by a thick frame.

In this way, the operator of the transmission apparatus monitoring terminal E6 can identify 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 the operator having the transmission apparatus monitoring terminal frequently moves between different offices, the current office can be identified at a glance at the destination office. For this reason, the risk of erroneous operation, such as accidentally clicking a clicked and unfamiliar location, is significantly reduced. Further, the time required for the operation can be reduced.

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