Title:
METHOD FOR COLLECTING ALARM OF NETWORK
Document Type and Number:
Japanese Patent JP2705683
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for collecting alarm for speedily collecting important alarms.
SOLUTION: Plural local devices 3 (3a-3c) with one center device 1 as a center are connected by a multi-drop line 10 using synchronous LAN by a synchronous clock supply device 2, and the center device 1 monitors the alarms generated from the local devices 3. Priority is given by the respective types of the alarms and alarm requests to which priority codes are added are transmitted from the center device 1 to the local devices 3 in synchronizing with a network for respective priorities. The local devices 3 receive the alarm requests corresponding to the priority codes added to the alarm requests and transmit alarm responses by prescribed time slots allocated to the pertinent local devices 3. The center device 1 receives the alarm response and monitors the network. Thus, the important alarm is preferentially collected.
