2. Description of the Related Art Conventionally, in a supervisory control terminal in an optical transmission system, when monitoring a failure by displaying a summary screen of each optical transmission terminal device (hereinafter, referred to as a monitored device), it is determined in advance. A summary screen based on the device configuration was created and displayed, and fault monitoring was performed.

In such a monitoring and control terminal, if the device configuration of the monitored device differs for each station, it is necessary to change the configuration information in accordance with each monitored device connected to each monitoring and control terminal. Was. Since each station has a different device configuration, the configuration information set in the monitoring control terminal has to be separately managed for each station.

In the optical transmission system, the operation history of each monitored device, the history of error occurrence cancellation, the operation history of the monitoring control terminal, and the like are displayed on the screen as character data and stored therein. The stored character data is mainly used for investigating the cause when some kind of equipment failure occurs on a system or a device.

[0005] In a monitoring control terminal that performs monitoring control of a monitored device using a multi-window system, what kind of board is mounted in each subrack constituting the monitored device and in what order. When the monitored device notifies the monitoring control terminal of a device failure from the monitored device, the monitoring control terminal
A window that displays the subrack-level mounting diagram including the failed board is automatically opened, and the faulty board is blinked or the display color is changed on the subrack-level mounting diagram to indicate the location of the failure. Are displayed so that they can be visually recognized. If multiple device failures occur,
The number of windows required to display the subrack level is displayed on the screen as many as required to display the fault, and the fault location is displayed using the subrack mounting diagram.

As described above, in the conventional monitoring and control system, when the equipment configuration of the monitored device differs for each station, the monitoring control terminal connected to each monitored device has a different configuration. Since the configuration information to be constructed is changed and separately managed for each station, there is a problem that it takes much time and effort. Further, once the configuration information is determined, there is a drawback that it is not possible to connect to monitored devices having different device configurations.

In the conventional monitoring and control system, the operation history of each monitored device, the history of error occurrence cancellation, and the operation history of the monitoring control terminal are displayed on the screen as character data except for the screen representing the latest state. Therefore, the operator has to read necessary data while tracing back and forth character data arranged in time order. Furthermore, whether any state change has occurred in the apparatus during the absence of the operator, and if so, what kind of state change has occurred at what timing and has changed to the current state. It was difficult to obtain information immediately.

Further, in the conventional monitoring and control system, when reading out a plurality of fault occurrence states having different degrees of urgency in different sub-racks which occur almost simultaneously in each monitored device, the monitoring and control terminal performs a reading process. Because the windows are displayed in the same order, the window that displays the less urgent problems may be displayed above the window that displays the more urgent problems. There was a problem that it was difficult to understand. Also, when multiple failures with different urgencies occur in different subrack almost simultaneously,
If the monitored device first notifies a suburb of a failure with a high degree of urgency that has occurred in one subrack, and then notifies a subrack of a failure with a low degree of urgency that has occurred in a different subrack, the supervisory control terminal will first receive the urgency The operator displays a window that displays the most urgent problems, and then displays a window that displays the less urgent problems received later, on top of the earlier displayed window that displays the more urgent problems. There is a problem that it is difficult to understand that a high-level failure has occurred.

At bit 0 of the contact A, there is no extension frame at 0, and there is an extension frame at 1 bit. The contact B can detect the presence or absence of the low-speed I / F shelf.
0 to 4 indicate that there is no shelf and 1 indicates that there is a shelf.

FIG. 3 shows a configuration information memory that is set by the configuration information storage unit 14 based on information on the device configuration contacts. The memory A stores data of 0: none, 1: present as extension frame information. In the memory B, values of 1 to 4 are set as information on the number of low-speed I / F shelves.

FIG. 4 shows a summary screen automatically constructed by the monitoring control terminal based on the configuration information corresponding to the device configuration. Type A is the basic configuration of the monitored device 1, and COM
It has a shelf, a high-speed I / F shelf, and low-speed I / F shelves 1 and 2. It is shown that four types of device configurations from type B to E can be configured by further adding a shelf to the basic configuration or adding a rack. Type B and C are low speed I
One or two / F shelves are added, and there is no additional rack. That is, type B has a total of three low-speed I / F shelves, and type C has a total of four low-speed I / F shelves. The types D and E have an extension frame. In the type D, the low-speed I / F shelves 3 and 4 are added. In the type E, the low-speed I / F shelves 3 and 4 are added.

The operation of the above configuration will be described below. First, a method of setting configuration information in the monitored device 1 is shown in FIG.
This will be described according to the flowchart of FIG. When the monitored device 1 is started, information on the presence or absence of an extension is read from the contact A according to an instruction from the function control unit 13 to the device configuration contact detection unit 11 (step S1). Based on the result, the extension information is set in the configuration information memory A (step S2). Similarly,
Information on the presence or absence of the low-speed I / F shelf is read from the contact B (step S3), and the number of low-speed I / F shelves is set in the memory B (step S4).

Next, a method of automatically constructing a summary screen based on the device configuration in the monitoring control terminal 2 will be described with reference to the flowchart of FIG. When the monitoring control terminal of the operation unit 22 is activated, the communication control unit 2 is activated by an instruction from the function control unit 23.

1) In response to the request, the configuration information is read in accordance with an instruction from the function control unit 13 (step S12). The read configuration information is transmitted to the monitoring control terminal 2 via the communication control unit 15 as a configuration information read response (step S1).
3). The monitoring control terminal 2 receives the configuration information read response (step S14), and determines which one of the types A to E according to the equipment configuration, based on the presence or absence of the extension frame read from the monitored device 1 and the number of low-speed I / F shelves. The summary screen is automatically constructed by the screen construction unit 24 (step S15). The automatically constructed screen type is stored in the configuration screen storage unit 26 (step S16), and a summary screen of the monitored device 1 is displayed on the screen display unit 25 (step S1).
7).

Next, a procedure for displaying a fault on the monitoring control terminal 2 when a fault is detected on the monitored device 1 will be described with reference to the flowchart of FIG. When the failure detection unit 12 of the monitored device 1 detects a failure such as a board failure (especially the low-speed I / F shelf 3 or shelf 4) (step S20), the function control unit 13 sends the information to the communication control unit 15 via the communication control unit 15. Is transmitted to the monitoring control terminal 2 (step S21). In the monitoring control terminal 2, the communication control unit 21 receives the failure information (step S22), and sends the screen display unit 2 from the function control unit 23.
A display instruction is passed to the device 5 and the type of the automatically constructed summary screen is read from the configuration screen storage unit 26 (step S23), and a failure detected according to the device configuration is displayed (step S24).

As described above, according to the present embodiment, even if the device configuration of the monitored device is different, the configuration information is read from the monitored device, and a summary screen is automatically constructed based on the configuration information. A monitoring control terminal can also be connected to the monitored device having the configuration to perform monitoring control.

The outline of the second embodiment of the present invention will be described below. In the second embodiment, the state history data of the monitored device is collected by the communication unit at all times or at an arbitrary interval, and a change point input in advance is selected from various state statuses that the collected state history data can take. Those that match the search condition (here, “Major alarm”) are detected. This makes it possible to detect a state change point that needs to be displayed on the monitoring control terminal. Furthermore, a screen image to be displayed on the terminal at the time of detection is calculated and created by performing a normal program process, and the screen image is stored and managed internally in the same size, or reduced or compressed. Then, the stored multiple screens are displayed simultaneously with the current latest screen. Since these screen images are managed inside the monitoring control terminal together with the detected conditions, time, display order, etc., some or all of them can be displayed in any order, and unnecessary screens can be deleted or searched. it can.

FIG. 8 is a functional block diagram of the second embodiment of the present invention. The monitoring control terminal 50 includes a communication control unit 51, a history data storage unit 52, a history data change point detection unit 53, and a screen data storage unit 54. , Screen display control unit 55, operation unit 5

The operation of the above configuration will be described below.
Based on the condition of the change point data condition storage unit 57 set in advance by the operator by the operation unit 56, the communication control unit 51 filters the data obtained from the monitored device 60 by using the history data change point detection unit. Apply at 53. When a change point is detected in the history data change point detection unit 53, the screen display control unit 55 stores the detected change point in the display screen data storage unit 54, and displays the detected change point in response to an instruction from the operation unit 56. Display on the screen.

FIG. 9 is an internal data configuration diagram specifically showing the structure of the data stored in the history data storage section 52 described above. In FIG. 9, the memory destination indicated by the address of the screen data points to the head address of each screen data stored in the screen data storage unit 54. Date / time is
At the time when the change point occurs, the received data storage unit 59
Shall be included in History screen number Dx (x: x
= 1... N, N is the maximum value) means the x-th history data. Dx-1 is one (previous) data before Dx (x = 1,..., N). * In the figure indicates the history screen No. D1
Means that the alarm of X has changed from the ON state (occurrence) to the OFF state (cancellation). In the stored data table, an alarm that satisfies a change point search condition (here, an alarm that satisfies the “Major alarm”, for example, an alarm of Q is ON)
State (occurrence)). At the same time, the date / time of October 8, 9:00, and the screen data before the change are stored.

FIG. 10 is a flowchart for explaining the operation of the monitoring control terminal. First, the history data (Log data) of the monitored device 60 is fetched and stored inside by the communication means (step S31). Next, it is determined whether or not a change point that matches the set level (item) is detected from the data (step S32).
If it is detected, the latest (changed) data is displayed large in the center of the screen as before (step S33). The data before the change is stored in Dx (x = 1,..., N) in the accumulation table.
(Step S34). At this time, it is determined whether or not the number of accumulated data exceeds the maximum value N (x> N) (step S35). If the number exceeds, the old data (D1) is deleted and x = 1 (step S40). ,
Proceed to step S36. If not, the process proceeds directly to step S36. In step S36,
It is checked whether there is any change in the accumulated data (whether the data detected this time is release information of the previously detected data) or not, and stores the time data of the paired data Dx 'in the accumulation table. (Step S37). Next, a bit map of the address indicated by the accumulated data (Dx) is displayed at the screen edge together with the latest data of the processing in step S33 (step S38).

On the other hand, if no change conforming to the setting item is detected in the judgment at step S32, the character data is displayed on the screen in the scroll area as usual, and the data is accumulated (step S39). .

FIGS. 11A, 11B and 11C show screen display examples. FIGS. 11A and 11C show a state change in a configuration diagram and the like of the apparatus, and FIG.

In FIG. 11A, the right screen 101 is displayed.
Shows a screen in the latest state in which communication paths (paths) are established between the nodes A to E. 100A, 100B, and 100C on the left screen 100 are three screens each showing a previous history state, and show a change in the path state. These screens can be scrolled between D1 and Dn.

In FIG. 11B, a screen 103 on the right side is a screen of the latest state of a graph in a device setting diagram or the like. 104 on the left screen 104
Reference numerals A and 104B denote two screens each showing a previous history state, thereby indicating a state change of the graph. These screens can be scrolled between D1 and Dn.

In FIG. 11 (C), the upper screen 105A of the right screen 105 shows the urgency of the alarm when the input signal is abnormal. The narrower the hatching width, the higher the urgency. ing. The lower screen 105B shows the urgency of an alarm when a hardware failure occurs on a board or the like, and indicates that the narrower the hatching, the higher the urgency. 106A and 106B on the left screen 106 are two screens each showing a previous history state, and indicate a change in the state of an alarm. These screens can be scrolled between D1 and Dn.

As a modified example, by providing the display state storage unit 58 at the time of the previous operation shown in FIG. 8, even if the terminal is not always connected to the monitored device, the previous information can be displayed. Thus, the difference from the current state can be known.

Also, since the operation history can be displayed when the same operation is performed, it is useful for preventing operation errors and noticing operation errors.

Hereinafter, a third embodiment of the present invention will be described in detail. FIG. 12 is a block diagram showing a flow of processing according to the third embodiment of the present invention. The operator reads the fault state of the monitored device 220 from the operation unit 201 of the monitoring control device 6
When requesting 00, the transmission / reception message processing unit 202 generates a failure information read request message 610 for the monitored device 220 and transmits it to the monitored device 220 via the communication control unit 203.

One or more failure information read request response messages 611 of the monitored device 220 are transmitted to the communication control unit 2.
03 to the transmission / reception message processing unit 202.

The transmission / reception message processing unit 202 reads out information on the failure occurrence position and its urgency from the received one or more response messages 611, and indicates the failure occurrence position information, the urgency information, and the failure state readout. The event information is passed to the failure display control unit 204 as a screen display request 632 of a failure information read request.

The fault display control unit 204 determines a fault display position and a fault display color from the fault occurrence position information and the urgency information. Further, the priority of the window display determined in the processing of FIG. 15 described later is determined. Then, a window to be newly opened is determined with reference to the failure display window management table 205. The fault display control unit 204 issues a new window generation request 627 and a front display request 625 to the window control unit 206 in the order of lower priority as needed, so that the window is displayed at the top of the overlapping window. Request.

Next, the fault display control unit 204 passes the new drawing flag, window identifier, screen identifier, fault display position, and fault display color to the fault screen drawing processing unit 207.

When a new drawing is required, the fault screen drawing processing section 207 reads the fault display screen data to be displayed from the fault display screen data section 208 and draws it on the window identified by the window identifier. Further, a failure display screen is drawn in a corresponding window based on the information on the failure display position and the failure display color received from the failure display control unit 204.

FIG. 13 is a flowchart showing details of the processing in the fault display control unit 204 described above. First,
It is determined whether the message is received from the transmission / reception message processing unit 202 or the operation unit 201 of the monitoring control device (step S50). In the case of the transmission / reception message processing unit 202, the transmission / reception message processing unit 202 sends a fault occurrence position,
The urgency and event information are received (step S54).
Next, it is determined whether the event information is a response to a failure information read request or a warning notification (step S55). In the case of an alarm notification, a step of FIG. 17 described later is executed. If the event information is a response to the reading of the failure information, a failure display screen to be displayed on the window is selected from the plurality of failure display screens from the failure occurrence position information (step S56). It is determined which part of the screen is to be displayed as a failure (failure display position) (step S57). In addition, a failure display color is determined from the degree of urgency for each location where each failure is displayed (step S58).

Next, a fault having the highest urgency among the faults displayed on each fault display screen is selected, and that urgency is set as the highest urgency of this screen. The highest urgency of each failure display screen is compared by sorting processing or the like, and a priority is determined from a screen having a high highest urgency to a screen having a low highest urgency (step S59). This order is used as the window display priority. FIG. 15 is a flowchart showing details of the processing procedure for determining the priority.

First, a certain screen is set as a target screen (step S67). Next, the degree of urgency of one failure displayed on the target screen is substituted for the maximum urgency parameter of the screen (step S68). Next, the urgency of the failure displayed on the other target screen is compared with the value of the highest urgency parameter, and if the urgency is higher than the highest urgency parameter value, the highest urgency parameter is rewritten (step S69). . It is determined whether the comparison with the value of the highest urgency parameter has been completed for all the faults displayed on the target screen (step S70), and if NO, the process returns to step S69. In the case of YES, the value of the highest urgency parameter is set as the highest urgency of the target screen (step S71).

Next, it is determined whether or not the highest urgency has been determined for all the failure display screens (step S72).
In the case of O, the process returns to step S67. In the case of YES, the respective failure display screens are rearranged in descending order of the highest urgency. This order is set as the window display priority (step S73).

After the priority order determination processing in step S59 in FIG. 13, the steps in FIG. 14 are executed. That is, the fault display control unit 204 performs reference 634 of the fault display window management table 205 managed by the fault display control unit 204 to obtain information on the fault display window that is open at that time. This failure display window management table 205
Is a table for managing the window identifier of the fault display window that is open at that time. The failure display control unit 204 determines a window that needs to be newly opened among the windows to be displayed based on the result of the reference (step S60).

Next, the failure display control unit 204 displays the failure display windows sequentially from the lowest priority based on the display priority of the windows (step S).
61). Next, it is determined whether or not it is necessary to open a new window (step S62). If it is not necessary to open a new window, the window control unit 206 determines that the window has already been opened for the fault display window that is already open. A front display request 625 is requested so as to be displayed at the top of the overlapping windows (step S63). Next, a new drawing flag indicating whether or not a new drawing is to be performed on the fault screen drawing processing unit 207, a window identifier of a window to be drawn, and a screen for identifying a fault display screen to be displayed on the window The information on the identifier, the failure display position, and the failure display color is passed to display the failure in the window (step S64). It is determined whether the processing has been completed for all windows, and if not, the process returns to step S61 (step S6).
7).

On the other hand, if it is determined in step S62 that a new fault display window needs to be opened,
The fault display control unit 204 issues a request 627 for generating a new window to the window control unit 206, and also requests a front display request 625 so that the window is displayed at the top of the overlapping window (step S).
65). After the window is created, the window identifier obtained from the window control unit 206 at the time of window creation is added to the failure display window management table 205 (step S66).

Next, the fault display control unit 204 controls the window control unit 206 when a new drawing flag and a window are generated.
The window identifier obtained from the above, the screen identifier for identifying the screen for failure display to be displayed on the window, the failure display position, and the information on the failure display color are passed to the failure screen drawing processing unit 207 as a failure screen drawing request 635. The failure is displayed in the window.

Here, returning to the flowchart of FIG. 13, in step S50, the operation unit 2 of the monitoring control device
If it is determined that the received request is received from the target 01, the failure display control unit 204 determines whether the received request is a request 601 for closing the failure display window or a time change request 602 for the window priority display control target, and changes the time. Request 602
In the case of, the step of FIG. 18 described later is executed.

When a request 601 for closing the fault display window is received from the operation unit 201 of the monitoring control device,
The fault display control unit 204 determines the window identifier of the window to be closed, requests the window control unit 206 to issue a request 630 to close the window (step S52), and displays the fault display window management table 205.
The window identifier of the closed window is deleted from (step S53).

The processing in the fault screen drawing processing unit 207 will be described below in detail with reference to FIG. First,
The failure screen drawing processing unit 207 determines whether or not the screen is a new screen by looking at the new drawing flag received from the failure display control unit 204 (steps S74 and S75). In the case of a new drawing, the fault display screen data unit 208 is set using the screen identifier as a key.
The failure display screen data is read in response to a read request 636 to the server, and the failure display screen data is drawn on the window having the specified window identifier (step S76). Further, a failure display screen is drawn on the window having the specified window identifier based on the information on the failure display position and the failure display color (step S77). If it is not a new drawing in step S75, the above-described step S77 is immediately executed without executing step S76.

Next, an embodiment in the case where the alarm notification message 612 is received from the monitored device 220 will be described. The alarm notification message 612 received in FIG.
Is a transmission / reception message processing unit 2 via the communication control unit 203
02.

The transmission / reception message processing unit 202 reads out information on the fault occurrence position and its urgency from the received alarm notification message 612, and outputs the fault occurrence position information and the urgency information and the event information indicating the reception of the alarm notification as an alarm. The notification is passed to the failure display control unit 204 as a screen display request 633 of the notification. The fault display control unit 204 determines the priority of the window display determined by the above-described processing of FIG. 15 for the alarm notification received within a predetermined time. The subsequent processing example is the same as the processing example in the failure state reading.

FIG. 17 is a flowchart showing details of the processing of the fault display control unit 204 in a modification of the third embodiment.

When the event information is the alarm notification reception, the failure display control unit 204 selects a failure display screen to be displayed in the window from the plurality of failure display screens based on the notified failure occurrence position information ( Step S78) Further, which part of the screen is to be displayed as a failure (failure display position)
Is determined (step S79). Further, a failure display color is determined based on the urgency of the alarm notification (step S80).

Next, a notification waiting flag indicating whether or not to wait for the next alarm notification is checked, and it is determined whether the notification waiting flag indicates "standby" (step S8).
1) If it indicates, the process proceeds to step S83. Also,
If not, the notification standby flag is set to "standby", the timer is started (step S82), and the process proceeds to step S83. In step S83, a next alarm notification message 613 to be notified later is waited until the time registered in the window priority display control target period parameter elapses. If the notification standby flag has already been set to “standby”, the process waits until the timer times out.

Next, it waits until a timeout occurs in the timer (step S84), and when the timeout occurs, rewrites (resets) the notification waiting flag to "no waiting" (step S85). Next, each alarm notification message 61 received during the standby period is included, including the alarm notification message 612 in which the notification standby flag is changed to “standby”.
With respect to 2, 613, the display priority of the fault display window for displaying the notified fault is determined in the same procedure as the procedure for determining the window display priority when reading the fault status (step S86).

The subsequent processes of the fault display control unit 204 are the same as the processes of the fault display control unit 204 in reading the fault status.

Next, a description will be given of a modification in which a function of changing the time range in which the priority display control of the window is performed when a plurality of alarm notifications are received by an operation from the operation unit 201 of the monitoring and control apparatus is added. In FIG. 18, the operation unit 201 of the monitoring control device passes a time change request 602 for the window priority display control target to the fault display control unit 204. In response to the time change request 602, the fault display control unit 2
04 rewrites the window priority display control target time parameter (step S87), and then returns the control result 603 of the time change for the window priority display control target to the operation unit 201 of the monitoring control device (step S88).

According to the present invention, what kind of equipment configuration is monitored by reading configuration information from the monitored device and automatically constructing and displaying a summary screen of the monitored device based on the configuration information. Fault monitoring can be performed by connecting a monitoring control terminal to the device. Therefore, the monitoring control terminal can be installed in the station building without changing the configuration information inside the monitoring control terminal even for the monitored devices having different device configurations.

Further, according to the present invention, a plurality of screen images at the time when the change point is detected can be displayed simultaneously with the latest screen. For this reason, even if the operator is absent from the monitoring control terminal, when heading to the terminal, during the absence, whether or not any state change has occurred in the monitored device,
Alternatively, the content of how the current state has been reached through can be seen as a transition of the same screen specification simultaneously with the current screen image, and can be easily recognized.

Further, according to the present invention, when a plurality of device failures with different alarm urgencies occur simultaneously in different subracks, and when a device failure with a different alarm urgency differs in different subracks for a predetermined period of time. When the monitoring and control system displays the fault location of the faulty device, the window displaying the higher urgent fault is displayed above the window displaying the lower urgent fault. An emergency with a high degree of urgency can be preferentially displayed to the operator.
