Centralized alarm monitoring system and method of power system terminal communication access network

Abstract

The invention discloses a centralized alarm monitoring system and method of a power system terminal communication access network. The method comprises the following steps: alarm collection: receiving real-time alarm messages reported by device network management systems, synchronizing the real-time alarm messages of the device network management systems to an alarm processor module to provide alarm and processing data sources for alarm; alarm preprocessing: performing normalized processing and classified compression on the collected alarm messages; alarm monitoring: displaying all kinds of preprocessed alarm messages on an alarm operating floor and a network topology diagram in real time, and forwarding important alarm to operation and maintenance personnel through short messages, emails and in station message means for important focus; fault diagnosis: performing analysis, diagnosis and qualitative diagnosis on the alarm according to the experience in an alarm processing experience library, and identifying all kinds of possible fault reasons inducing the alarm; and fault processing scheduling: locating the geographic position of a fault point according to the fault diagnosis result and the operation and maintenance group in charge, processing a work order, and scheduling the corresponding operation and maintenance group to remove the fault.

Description

technical field [0001] The invention relates to a centralized alarm monitoring system and method for a terminal communication access network of a power system. Background technique [0002] The terminal communication access network is a communication access network established for power distribution, power consumption data collection, power fiber-to-the-home, power marketing, power consumption interaction, etc. Since the terminal communication access network has various technical systems and manufacturers' model types The characteristics of various and different business application requirements have fundamentally increased the difficulty of operation, maintenance and management of the terminal communication access network. At present, in the actual operation and maintenance work, access network communication monitoring and fault handling mainly rely on business department declarations and multiple sets of equipment network management alarm monitoring. Alarm monitoring is di...

Problems solved by technology

[0004] Due to the fault tolerance mechanism and fault warning mechanism of communication equipment, the number of alarms generated by the equipment is far greater than the number of actual faults. Effective alarms that truly reflect the occurrence of faults are usually submerged in a large amount of suggestive alarm information and are difficult to identify

Moreover, during the construction of power communication network maintenance and methods, a large number of alarms of communication equipment will also be triggered. Such alarms are not caused by network equipment failures. Not only do they have no reference significance for analyzing failures, but they will disperse and interfere with operation and maintenance personnel. attention

In addition, different equipment manufacturers and different versions of equipment network management northbound interfaces also have huge differences in the definition, classification, classification, and description of alarms, and even the languages ​​used are not uniform, which increases the difficulty of alarm reading and analysis. And it is not conducive to the accumulation, refinement and exchange of alarm handling experience
