Describe embodiment of the invention (see figure 6) in detail below in conjunction with Fig. 7 management method be provided:
S700: be the power supply of the sensing element on the fiber adapter, the power supply control operation can be adopted manual connection external power supply mode, or by operation control module activation powered operation;
S701:RFID read with the identification module active optical fiber on the RFID label of appointment, read the RFID information on the RFID label; Concrete, RFID read with identification module in the RFID card reader read the RFID information of RFID label of the optical fiber of insertion, send to the operation control module; If also be attached with the RFID label on the fiber adapter, RFID read with identification module active optical fiber adapter on the RFID label of appointment, read the RFID information on the RFID label, send to the operation control module;
S702: the operation control module has judged whether to read new RFID, judges promptly whether the RFID information that reads exists, and if there is no (promptly being new RFID) then enters step S703, otherwise selects next RFID label, repeated execution of steps S701;
Preferably, can utilize the RFID information of the RFID label on the optical fiber and the RFID information of the RFID label on the fiber adapter to carry out verification, determine whether coupling, whether allow insertion etc.Concrete, can operate control module again and carry out verification in this locality, also information can be sent to network management center and carry out long-range verification.
S703: the state collection module reads the state indication of state of the expression fiber port of port of passive optical assembly module output;
Concrete, state detection unit in the passive optical assembly module is responded to the variation of optical fiber connection status under electric power thus supplied, wherein the variation of optical fiber connection status has particular kind of relationship in the parameter of the sensing element of state detection unit and the fiber adapter, as sensing element is capacity cell, or inductance element, or Hall element, under electric power thus supplied, the variation of sensing element parameter response optical fiber connection status in the fiber adapter, it is the variation (variation that optical fiber has or not of optical fiber connection status, optical fiber enters, optical fiber leaves etc.) cause the electric field of cavity of receiving optical fiber or the variation in magnetic field, thus cause the variation of sensing element parameter.The state indicating member of state detection unit, detect the variation of the parameter of described sensing element, the state indication of the state of output expression fiber port, the state indication can be " 0 " and " 1 " digital signal of high-low level indication, perhaps other predefined signals.
The state collection module is according to predetermined state encoding rule output state index signal, and this status indication information is directly delivered to the operation control module.
S704: the condition indicative signal of operation control module accepting state collection module output, judge whether the optical fiber connection status changes, do not carry out S705 if change; Carry out S706 if change;
S705: the operation control module judges whether to read in new RFID, if there is not execution in step S703; If have then execution in step S707;
S706:, and the RFID information and the fiber adapter information of association sent to administrative center with refresh with RFID information and fiber adapter associating information; Return step S701;
S707: operation control module outputting alarm, as audible and visual alarm or only be the light alarm, the expression operation is wrong; To forbid that all ID read in and state recognition this moment, in order to avoid criminal manipulation may cause the disorder of ODN database, cause unnecessary doing over again.
S708-710: after system enters alarm status, need to remove alarm and just can restart to carry out ID typing and state recognition.Can adopt following 2 conditions to remove alarm: manual cleared alarm; The alarm clearance timer perhaps is set, when entering alarm status, system starts the alarm clearance timer, when overflowing, removes by the alarm clearance timer alarm, choosing is arranged, the operation of alarm judges whether in the further execution in step 709 to reset when the alarm clearance timer overflows, do not alarm then the operation of releasing alarm in the execution in step 710 if do not reset, if the operation that resets and alarm then restart the alarm clearance timer in the execution in step 708.
As previously mentioned, existing optical node all is Passive Optical Components, can not initiatively inform self essential information and with the link information of other optical nodes or optical fiber cable, therefore can only rely on the manual record in the installation process to obtain the relevant information of above-mentioned maintenance.Therefore traditional ODN installation and maintenance mode wastes time and energy, and back current cost height, thereby causes the CAPEX of whole Fiber Access System and OPEX to remain high.The disclosed technical scheme of the embodiment of the invention fundamentally allows the ODN engineering break away from the technical scheme of traditional manual type, and it is time saving and energy saving to have, the automatic typing of information, information is simple and clear, and the simple basic characteristics of later maintenance can fundamentally reduce the OPEX of operator.
The above; only be the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
