Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of equipment of outdoor version optical fiber access node composite power supply and method and system of switching realized.
Background technology
Along with the fast development of the communication technology, operator is for solving the demand of client's full-service, and more options FTTx is as the best scheme that solves various high bandwidth service accesses.The FTTx technology is mainly used in the access network fiberize, and to subscriber terminal equipment, local side apparatus is that optical line terminal, ustomer premises access equipment are optical network unit or Optical Network Terminal to scope from the local side apparatus of regional telecommunications room.In the FTTx process of construction, outdoor version optical fiber access node because possess that cost is low, the construction period is short, can realize the advantage of laying foundations fast, so adopted widely by vast operator.Prior art roughly is divided three classes as the electric power system that outdoor version optical fiber access node uses: power supplied locally adds batteries, power supply far away and solar powered.This three classes power supply all possesses their characteristics and inferior position separately.At first power supplied locally adds the batteries technology, advantage with electric energy abundance, but after this locality has a power failure, batteries only can be kept very little a period of time, can not accomplish truly that optical fiber access node power guarantees, batteries causes batteries to descend useful life after repeatedly discharging and recharging because the access device caloric value is bigger easily simultaneously, causes maintenance cost to increase.And power supply far away adds the composite rope technology, have the advantages that power supply far away is not influenced by local power supply, but owing to be subjected to the influence in composite rope copper cable footpath, and can only be in the short distance of 200-400V transmission under the higher voltage, the long-time use because the cable heating causes the aging of composite rope easily.Solar powered, have the advantage of green energy resource, the low-carbon (LC) energy, but because the Efficacy Problem and the boisterous influence of solar panel, so solar powered first supply power mode that can not become the optical fiber access node.
Summary of the invention
For solving the technical problem of outdoor version optical fiber access node composite power supply, patent of the present invention provides a kind of equipment of optical fiber access node composite power supply and method of switching of realizing, can realize the advantage of above-mentioned three kinds of common power supply techniques is integrated, and key step comprises:
At first be according to power supplied locally, power supply far away, batteries, solar powered characteristics, design, take other mode of different priorities, electrical source of power output port circuit is controlled;
Record is according to each input port real time data, and carries out power supply according to the concrete condition of input port and switch;
It is power supplied locally that power supply switches order of priority, power supply far away, and storage battery power supply, solar powered;
If in the power input mouth, the power mode of AC/DC is normally then taked in local AC/DC input earlier.If local AC/DC input is undesired, then the powershift unit can check whether the Remote Power Supply system imports normally.If Remote Power Supply is imported normally then is temporarily switched to supply power mode far away, and alarms to local side, signal power supplied locally fault;
When switching to supply power mode far away, carrying out timing per hour judges once according to port data, if AC/DC recovers normal and above 15 minutes, then with powershift to the power supplied locally mode, as normal or recovery time as yet not above 15 minutes, then continue to adopt supply power mode far away inquiry once more up to one hour;
If when power supplied locally and power supply far away all went wrong simultaneously, whether batteries can be checked in the powershift unit, and whether voltage was normal, have.Then automatically switch to the storage battery power supply mode if any electricity, alarm to local side simultaneously.When switching to the storage battery power supply mode, the powershift unit can be monitored each port in real time, if power supplied locally recovers more than 15 minutes or service restoration far away more than 5 minutes, then switches from the higher supply power mode of trend priority level;
For solar electric power supply system, the powershift unit can check formerly whether solar panels are exported normally (assurance be by day or non-overcast and rainy), reexamine local batteries and whether need charging, then charge to batteries if desired by inversion unit, as not needing then according to actual conditions, as the auxiliary delivery outlet of local 48V.
Patent of the present invention provides a kind of equipment of optical fiber access node composite power supply and system of switching of realizing, comprising: electrical source of power input system, electrical source of power detect warning system, electrical source of power switched system and electrical source of power output port.Wherein:
The electrical source of power input system is responsible for local alternating current 220V, composite cable are far inserted for the power supply of direct current 380V, solar panel direct current 12V, and convert thereof into by transducer or inverter and to be direct current 48V, the electrical source of power connecting system comprises: local AC/DC transducer, Remote Power Supply, batteries, the solar-electricity source inventer.
Electrical source of power detects warning system and is responsible for every inputoutput data of electrical source of power connecting system being monitored, being gathered and relevant information is passed to the electrical source of power switched system, produces relevant warning information simultaneously, reports to the police to local side by communication line.
Electrical source of power switched system, its core are the electrical source of power handoff algorithms, and it carries out processed according to the information that electrical source of power detects, warning system produced, and by controlling the circuit of electrical source of power output port, realize the electrical source of power switching.Produce relevant processing record simultaneously, send to the local side computer by communication line, carry out remote reporting, the local side computer also can carry out Long-distance Control to the electrical source of power switched system.The electrical source of power output port is responsible for carrying out 48V power supply to the outdoor version optical access node, simultaneously to the illumination of the supporting outdoor version cabinet of node, and temperature control, the gate inhibition, unit such as alarm carry out 48V and power.
Patent of the present invention, owing to adopt the composite power supply mode, by advanced person's power supply access technology; rational power supply handoff algorithms; perfect power supply detects the alarm system, the merging of several supply power modes that can outdoor version optical fiber access node is common, and real meaning is accomplished the full power protection.
