Description
Technical field
The present invention relates to a kind of method of real-time of ONU equipment operation conditions, belong to communication network comprehensive management technology field.
Background technology
EPON (ethernet passive optical network) communication network adopts point-to-multipoint topological structure, comprehensive ethernet technology and PON(EPON) advantage of technology, signal is at optical line terminal (OpticalLineTerminal, OLT) and between optical network unit (OpticalNetworkUnits, ONU) transmit.EPON(ethernet passive optical network) be a kind of novel intelligent acess network technology, it adopts point-to-multipoint structure, passive fiber to transmit, on Ethernet, provide multiple business.It has employed PON technology in physical layer, uses Ethernet protocol, utilize the topological structure of PON to achieve the access of Ethernet at link layer.Therefore, it combines the advantage of PON technology and ethernet technology: low cost; High bandwidth; Autgmentability is strong, flexibly service reconfiguration fast; With the compatibility of existing Ethernet; Management etc. easily.A PON(EPON) comprise the optical line terminal (OLT) that is installed on console for centralized control, a collection of supporting multiple optical network units (ONUs) being installed on customer site of one-level.
The terminal ONU of the chain structure that EPON is natural and cheapness makes it to become the most applicable mesolow distribution communication.
According to statistics, the power outage more than 95% that power consumer suffers is caused (deduction generation deficiency factor) by power distribution network.In distribution automation system, power taking and use are convenient in generally for of ONU equipment, and be usually deployed in the places such as switching station, load center, electric supply meter place, ring main unit, on-pole switch, transformer, due to residing bad environments, the frequency broken down is higher.According to the PON fault statistics Morbidity investigation of Japanese NTT communication company (starting FTTH in 2003 to build), ONU fault account for 69%.
Therefore, ONU equipment is monitored in real time, find fault early, and measure abort situation exactly, be convenient to isolate and repair fault in time, ensure ONU equipment reliability service to greatest extent.Ensure that distribution automation service communication is unimpeded, raising power supply reliability tool is of great significance.
Alarm is a kind of event report of the circular formation that managed object sends when particular event occurs, for transmitting warning information.It is that device fabrication manufacturer defines oneself, and produced by the equipment in network, be the message that a system sends, represent that it there occurs certain thing or exception, finally observed by network management personnel.
But, the corresponding multiple ONU of PON mouth due to 1 OLT, ONU equipment is equivalent to the remote end module of OLT, cause the also corresponding growth of network operation fault warning information scale and complexity, failure cause judges more complicated, only by plant equipment alarm, is difficult to find ONU equipment fault, often after the failure of power distribution automation devices communicating, just find ONU equipment fault.
The fault of ONU equipment is divided into three major types, and one is communication disruption, and two is that communication is impaired, and three is performance impairment; Because ONU equipment has two PON mouths usually, lead to two OLTPON mouths respectively, one is in line states at ordinary times, and another is in dormant state.If the passage that ONU two PON mouths lead to OLTPON mouth is all in malfunction, then ONU equipment fault is communication disruption; If a passage is in malfunction, system can automatically switch residue normal passage, this type of fault for communication impaired; If two passages are all in upstate, but due to spread of voltage, the reasons such as PON mouth is dirty cause hydraulic performance decline or the potential hazards such as data packetloss rate, and this type of fault is performance impairment.Observe and research through long-time, find that user is the most it is of concern that the fault of the first and second classes, therefore have studied Real-Time Monitoring emphatically and find the method for communication disruption and this two classes fault impaired that communicates.
Summary of the invention
