JPH05219145A - One station concentrated setting system for inner timepiece in network monitoring device - Google Patents

Abstract

PURPOSE:To accurately record time information without correcting the time information at the time of generating a fault by transferring time setting information between work station interface devices installed in respective stations. CONSTITUTION:The work station 2 of a master station 1 has an absolute timepiece to be the reference time for all stations and generates time information 3. A network monitoring device 4 displays the time of generating an alarm based on the information 3. The work station interface 5 receives the information 3 and transmits time setting information 6 to a slave station 7. On the other hand, the work station interface 8 of the slave station 7 receives the information 6 and gives the work station 9 time setting information 10. The work station 9 sets an inner timepiece based on the information 10 to generate time information 11 and a network monitoring device 12 displays the time of generating the alarm. Consequently, the same time can be set to the inner timepieces of the network monitoring devices of the respective stations.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized setting system for internal clocks of network monitoring devices in the fields of digital communication, data transmission, etc., and particularly functions as an alarm monitor of data transmission in a transmission line and a transmission device. The present invention relates to a centralized setting system for a network monitoring internal clock.

2. Description of the Related Art Conventionally, in the alarm monitoring by a network monitoring device,
The alarm generation time, which is one of the monitoring history information, is given by a unique internal clock of a workstation installed in each station.

[0003]

In the alarm monitoring by the conventional network monitoring device, the alarm generation time is given by the internal clock unique to the workstation installed in the station. Then, the time of the workstation of each station is set independently for each station. Therefore, the display time of the alarm output to the network monitoring device differs depending on each station.

On the other hand, when a failure occurs in the transmission line or in the transmission device, the alarm is transmitted to the related station. Therefore, the occurrence time information output to the network monitoring device of each station is very important for investigating the content of the failure and the cause of the failure. There is a difference in
First, there has been a problem that the time must be corrected between the network monitoring devices of each station.

[0005]

It is an object of the present invention to provide a centralized setting system for a monitoring device internal clock, which can improve the inconvenience of the conventional example, and particularly can accurately record the time information at the time of occurrence of a failure without any correction. The purpose is to do.

[0006]

According to the present invention, a workstation 2 of a master station 1 having an absolute clock serving as a reference time for all stations and generating time information, and a time information receiving means,
Workstation interface 5 on the master station side that sends time setting information to slave station 7, and workstation interface 8 on slave station 7 that receives the time setting information from the master station and outputs the time setting information.
And a workstation 9 of a slave station 7 for receiving time setting information output from the workstation interface 8 to set an internal clock and generating time information. This aims to achieve the above-mentioned object.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 shows a centralized setting system for one station of a network monitoring device internal clock which is an embodiment of the present invention. In this network monitoring device internal clock setting system, the workstation 2 of the master station 1 has an absolute clock serving as a reference time for all stations, and generates time information 3 for setting clocks of its own station and slave stations. The network monitoring device 4 of the master station 1 receives the time information 3 and displays the time when the alarm is issued based on the information. The workstation interface device 5 of the master station 1 also receives the time information 3 and transmits the time setting information 6 to the slave station 7.

On the other hand, the workstation interface 8 of the slave station 7 receives the time setting information 6 and sends the time setting information 10 to the workstation 9 of the slave station 7.
give. The workstation 9 sets the time setting information 10
Based on the above, the internal clock of the workstation 9 is set and at the same time, the time information 11 for setting the clock in the own station is generated. Similar to the master station 1, the network monitoring device 12 of the slave station 7 receives the time information 11 and displays the time when the alarm is issued based on the information.

That is, by installing the workstation interface as described above in each station, the time setting information is transmitted and received between the workstation interfaces and the workstations of all stations are set to the same time. As a result, the alarm generation time in the network monitoring device of each station is displayed based on the absolute clock of the workstation 2 of the master station 1.

As described above, according to the present invention, the work
Install station interface devices at each station
Time between the workstation and interface device
Internal clocks of all station workstations that send and receive information

Network monitoring equipment of each station based on the absolute clock of the station.
It is possible to set the same time on the internal clock,
Cause a failure in the transmission path or transmission device
When investigating the failure content and cause of occurrence
For each station's alarm occurrence time information, which is very important,
The same time without adjusting the time between the network monitoring devices
An unprecedented ability to reliably record and display
Network centralized system for internal clock monitoring
can do.
