DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized transmission apparatus for monitoring status information of a large number of transmission apparatuses at one location, and more particularly to a method for suppressing the monitoring of a specific apparatus.

In recent years, in order to improve the efficiency of maintenance work, there has been a demand for a centralized monitoring system with a centralized transmission device monitoring device that centrally monitors status information of a large number of transmission devices scattered in remote locations at one location. However, it is important for a maintenance person to estimate the location of a fault by separating and displaying device faults that are serious for the operation of the transmission network among a large number of transmission devices to be monitored. When monitoring a fault, it is often the case that a fault occurs for obvious reasons, such as during construction.If the fault is treated and displayed in the same way as other faults, it can be distinguished from a true fault that has occurred in the operating network. Unfavorable for maintenance work. For this reason, there is a demand for a function of suppressing transmission device failure monitoring that excludes a transmission device that is clearly in a failure state in advance.

[0003]

2. Description of the Related Art In a conventional centralized monitoring system, as shown in the block diagram of FIG. 3, information on a fault that has occurred in each transmission device to be monitored is collected, and the highest level monitoring and control device SV collects information. Send to centralized monitoring device. In the conventional method, the operation mode of the transmission device under construction among the devices to be monitored is set to under construction, and a failure state of the transmission device under construction is not notified to the higher-level supervisory control device SV. Had been.

[0004]

In the above conventional method,
Since the status mode of each transmission device monitored by the centralized monitoring device is set on each device side, it takes time to set the status. Since only the relatively new transmission device has the function of setting the state of the transmission device, there is a problem when centrally monitoring the old device that does not have the function. In the monitoring of the centralized monitoring device, there is a case where the transmission target device to be monitored is simply for the reason of suppressing the display of a fault from the fault management, not for a clear reason such as under construction, so if the state of this device is set as under construction, There is a problem that the status information is not notified to the intermediate supervisory control device SV. Therefore, it has been necessary to provide the centralized supervisory device with a function of suppressing monitoring of a specific transmission device. Further, in the conventional method, in order to reduce the amount of data transmitted to the centralized monitoring device by each SV device, a method of notifying the centralized monitoring device of monitoring information of only devices whose status has changed since the last monitoring is adopted. Therefore, if the centralized monitoring device unilaterally suppresses the failure monitoring, that is, if the current table is cleared and the subsequent information is ignored, the state of the device that occurred after the suppression becomes unknown, and Status monitoring becomes impossible. Furthermore, since the fault that is occurring remains in the device to be suppressed recorded in History as it is, a problem arises that it conflicts with the contents of the Current table of the centralized monitoring device. An object of the present invention is to realize a method for suppressing failure monitoring of a specific transmission device that does not contradict the contents of the Current table of the centralized monitoring device.

[0005]

The basic structure of the present invention for achieving this object is as follows. As shown in the principle diagram of FIG. A command transmitter 1 for sending a command C requesting the notification of the notification is provided in the centralized monitoring device 10, and a command C from the centralized monitoring device 10 is sent to a specific transmission device 21 whose monitoring is to be suppressed.
Is provided.

[0006]

According to the present invention, first, the command C sent by the command sending device 1 of the centralized monitoring device 10 is sent to the intermediate monitoring control device S.
The command C transmitted to the transmission device 21 to be monitored through V
The transmission apparatus 21 which has received and detected the state transmits the current state to the centralized central monitoring apparatus 10. Next, in the centralized monitoring device 10,
When the suppression of the monitoring of a specific device 21 is released, the command C is transmitted to the device 21 to be released, and the failure state is collected again. Then, when the monitoring suppression is executed, the centralized monitoring apparatus 10 stores the current state of the suppression target apparatus 21 in Curr.
ent Clear the contents of the memory and record the old state His
It is assumed that the fault occurring in the target device 21 has been recovered by searching for tory.

101, a current table creation processing unit 102 that collects information on the current state of the transmission apparatuses 21 to 2n to be monitored and creates a current table, and a history that records the past states of the transmission apparatuses 21 to 2n to be monitored. History creation processing section to be created
103, a current status display processing unit 104 for displaying the status of the current table, and history for displaying the history contents
It consists of a display processing unit 105.

When Suppress is ON, the display input processing unit 106 notifies the current table creation processing unit 102 and the like of a monitoring address for identifying the corresponding device. The current table creation processing unit 102 displays the current status of the notified transmission device.

The input processing unit 106 notifies the lower SV communication processing unit 101 of a monitoring address for identifying the device. Lower SV communication processing unit
101 sends a command C for requesting information on the current state to the corresponding transmission device through the lower-level SV device. In the order described above, each transmission device notifies the current state to the centralized monitoring device 10. Therefore, the centralized monitoring device 10 performs the same processing as normal processing to update the Current table. , History creation processing. In normal processing
In the case of the current table creation processing, upon receiving information on the transmission target devices 21 to 2n to be monitored from the lower SV communication processing unit 101, the current table creation processing unit 102 refers to the current table value from the monitoring address of the device, If the state of the device is Suppress, the process is abandoned.
