What accompanying drawing 1 was described is that ODN network of the present invention connects.In the FTTx system, hundreds of millions of optical fiber are connected to the terminal use from distributing cabinet.Also there is a section optical fiber to link to each other simultaneously between the distributing cabinet, forms link.Finally formed a huge ODN network.Adopt background manage software and portable terminal and on visual software, through thousands of indoor and outdoor distributing cabinet in wireless network (3G or WiFi etc.) or the cable network network management ODN network and the interior hundreds of millions of optical fiber of distributing cabinet.
Accompanying drawing 2 is that connector place to every tail optical fiber or jumping fiber increases a RFID electronic tag in the implementation process of the present invention, is called RFID electronics tail optical fiber or RFID electronics jumping fiber this moment.Each label all has a globally unique ID, can not change.Simultaneously, the capacity of 512b it/1K bit/2K bit is arranged in the label, can store information such as physical address or numbering.When no matter being New-deployed Network or old network upgrade, can on the optical fiber connector, add such RFID label.If jumping fiber is stored unique ID of the other side each other in the connector of two ends, perhaps store a same numbering.If tail optical fiber is then stored the physical address at other end place.Certainly except numbering and physical address; Can also the storing fiber optic route, the information of sequence location, the optical splitter that be connected to this root optical fiber or the Wiring module of optical fiber in optical cable, construction information (as; Personal information, temporal information), maintenance information (as, personal information, temporal information, problem information).These information can write through permanent plant in advance, write in the time of also can installing at the scene through handheld device.
What accompanying drawing 3 and accompanying drawing 4 were described is the annexation between plug-in RFID identifier Optical Distribution Frame or optical splitter and RFID electronics tail optical fiber and the RFID electronics jumping fiber.
Be automatically recognized after being inserted into fibre distribution frame or optical splitter for the ease of the wire jumper that has the RFID electronic tag or tail optical fiber; Designed and to have hung over the RFID identifier on optical fiber electric distributing frame or the optical splitter outward; Also can be when fibre distribution frame or optical splitter be produced, identifier is wherein embedded.Through plug-in or embedded RFID identifier on Optical Distribution Frame or optical splitter, discern the optical fiber that each root inserts contactlessly, and the insertion position of positioning optical waveguides, promptly be inserted on concrete some ports of Optical Distribution Frame/optical splitter.When identifier is in running order, all can be when any RFID electronics wire jumper or RFID electronics tail optical fiber are inserted into distributing frame or optical splitter by Real time identification, the information of its storage inside can be delivered to the RFID identifier in real time.
LED light and buzzer are all arranged on each identifier in addition.When certain RFID electronics jumping fiber or tail optical fiber are inserted in the position that should not insert, when perhaps insert the position that should insert, the LED lantern festival flicker of correspondence position, buzzer alarm simultaneously.Equally, when the keeper need insert (or deletion) RFID electronics jumping fiber or tail optical fiber at certain port of distributing frame or optical splitter, corresponding LED lamp also can glimmer, and the pilot operationp personnel operation increases ease for operation, reduces mistake.Even produce mistake because of carelessness, system also can in time alarm.
If under the identifier off position, RFID electronics jumping fiber or tail optical fiber are changed by mistake, when identifier re-powers work, can monitor out all mistakes automatically.
Accompanying drawing 5 is electronic lock and the electric power systems on the distributing cabinet.
Electronic door lock system is that the safety of RFID electronics jumping fiber or tail optical fiber provides safeguard.All electronics tail optical fibers or jumping fiber are all received distributing frame or optical splitter in distributing cabinet (or rack) the inner.So we increase electronic lock, i.e. an electronic door lock system for each distributing cabinet or rack.The software that only has the keeper of authority to utilize us to provide just can be opened electronic lock.When closing distributing cabinet or cabinet door, electronic lock can automatically lock.
The ODN network is a passive network, and intelligent management system will be considered this prerequisite.Under the overall background of energy-saving and emission-reduction, environmental protection, keep the passive characteristic of this system as far as possible.Therefore, electronic lock, controller, RFID identifier all are passive, are not work on power at ordinary times, are in off position.When they work when needs, utilize the USB power supply of PDA or notebook computer can the active electron lock, open electronic lock through the software in PDA or the notebook after, notebook or USB can give the power supply of RFID identifier, make it in running order.The RFID identifier in electronic lock and the distributing cabinet and the operating voltage of controller all are 5V.The USB mouth of portable terminal just can provide the enough energy.
The power supply of distributing cabinet and communication interface power on for electronic lock and controller, and communicate with.This interface is the USB mouth of attended operation personnel's portable terminal directly, and obtains power supply.Portable terminal sends instruction unpack electronic lock or monitoring in real time, every optical fiber of inquiry, guides wire jumper etc. to electronic lock and controller through this interface.
Accompanying drawing 6 is annexations of distributing cabinet internal controller and RFID identifier.During installation, controller generally is installed in the middle part of distributing cabinet, and Optical Distribution Frame or the optical splitter that has the RFID identifier all installed in its top or bottom.After the installation, controller and each identifier are coupled together with coaxial cable.Under the default situations, a controller has 48 interfaces, just can connect 48 RFID identifiers, can satisfy all standard distributing cabinet or rack.
In addition, controller will be connected on the power interface of distributing cabinet.When portable terminal is supplied power to distributing cabinet through the USB mouth, the controller activation work that also can be powered on.
Accompanying drawing 7 has been described software and the communication modes between the daemon software on the portable terminal and has been reached feature list separately.The two is through wireless network (3G, WiFi etc.) or cable network communication.
All ODN assets (distributing cabinet, distributing frame, optical splitter etc.) and link (jumping fiber, tail optical fiber and with the annexation of port) are all managed in background manage software, and the keeper can have integrated planning and management to whole link and assets.When the needs link changed, the keeper can send a job note to the software of operating personnel's portable terminal, and confirmed this time to operate information such as needed material and operation place.In addition, usually can't inquire about the link relation of the overall situation on operating personnel's portable terminal.At this moment, can ask background manage software to help its completion.Return results was given portable terminal after background manage software was accomplished.Certainly, background manage software has the function of a lot of statistical informations and form, data importing and derivation, data passes.
After receiving job note or Query Result on operating personnel's the portable terminal.The visual software that moves on the portable terminal is at first confirmed the material that this required by task is wanted, bootable if needed operating personnel's application to get or unified allocation of resources.Then, automatically the engineer is directed to the scene through cartographic information system (GIS).
After reaching the spot, find the distributing cabinet that needs operation.Supply power to distributing cabinet through the USB mouth.Send instruction through mobile terminal software and open electronic lock.After opening electronic lock, management software can have or not illegal connection by all interior RFID electronics jumping fiber tail optical fibers of this distributing cabinet of automatic inspection.Then alarm is arranged, do not have and then point out link intact.
Next operating personnel just can carry out its operation that needs arbitrarily.
Can in management software, import the link that will inquire about, as: the user side numbering or the title of certain root link, software systems can be sent instruction according to the numbering of input to controller at once, all optical fiber of controller control identifier scanning.After finding the port of corresponding optical fiber or tail optical fiber insertion, its pairing LED lamp will glimmer, and intuitively inform the user.Can show the pairing complete link of this tail optical fiber in the software simultaneously.
When job note need change (increase/deletion) to the wire jumper of certain bar optical fiber or tail optical fiber, the job note instruction can be specified any one node on the optical fiber place link that will change.As: shift out the tail optical fiber in No. 13 building 201 in the sub-district, software systems meeting automatic scan identifier finds the corresponding optical fiber connector of this tail optical fiber, LED lamp flicker simultaneously, the guiding client removes this tail optical fiber.If the mistake of removing, the LED lamp and the buzzer of identifier can be alarmed, and be correct up to operation.Remove the back engineer and need not to fill out the engineering confirmation form again, software confirms that automatically the worker is single, and reports upper background management system.
Certainly, hardware foundation and framework have been arranged after, software function can also constantly be expanded.Such as: when just adorning construction, the workmen fills in the construction information (as: operating personnel, set-up time) of each root link in the management software of automatic terminal, and these information can be saved in the RFID electronic tag, can inquire about at any time later on.Information in maintenance process also can write in the electronic tag, inquiry after being convenient to.
System configuration of the present invention is simple, less investment, and effect is obvious, not only is fit to the fiber management at ODN networking, also is suitable for the management of the enterprise network circuit of middle-size and small-size scale.
