Embodiment
As stated in the Background Art, in existing optical fiber state-detection scheme, concentrate on mainly whether optical fiber is communicated with and whether synchronous detection, information such as power loss for optical fiber then do not detect, thereby, can't detect the situation of the realization of the normal transmission that causes to guarantee signal because the power loss that optical fiber is caused institute's transmission signals is excessive and load sharing, can't satisfy by the optical fiber state-detection and in time find optical fiber hidden danger, guarantee the requirement of the normal operation of signal transmission.
In order to overcome such defective, the embodiment of the invention has proposed a kind of optical fiber condition detection method, by the luminous power and the optical fiber interface state of detection fiber interface, in time the power loss and the synchronous transmission situation of detection fiber have improved the accuracy of optical fiber state-detection operation.
As shown in Figure 1, be the schematic flow sheet of a kind of optical fiber condition detection method that the embodiment of the invention proposed, this method specifically may further comprise the steps:
Step S101, base station are detected each optical fiber interface respectively, determine the luminous power and the optical fiber interface state of corresponding optical fiber interface.
In the application scenarios of reality, carry out in order to realize optical fiber state-detection automation of operation, improve the efficient of optical fiber state-detection, the base station can be set carry out detecting operation according to the default optical fiber state-detection cycle.
Concrete, corresponding timer can be set in the base station, reach default optical fiber state-detection during the cycle current, triggering the base station detects each optical fiber interface respectively, timer perhaps is set in third party device, and reach the default optical fiber state-detection cycle current, and send corresponding Indication message to the base station, trigger the base station and respectively each optical fiber interface is detected.
Concrete triggering mode can be adjusted according to actual needs, and such variation does not influence protection scope of the present invention.
On the other hand, shake the flase drop that causes for fear of optical link, improve the accuracy of optical fiber state-detection, can carry out multiple cycles in an optical fiber state-detection cycle detects, and comprehensively obtain final optical fiber state-detection result according to detection case repeatedly, therefore, step S101 also can finish one time the optical fiber state-detection in the base station, and the execution that is triggered when reaching default cycle detection condition, the content of concrete cycle detection condition will be introduced hereinafter.
Certainly, adopt cycle detection, and the scheme of carrying out repeated detection in each cycle is a kind of preferred processing scheme that the embodiment of the invention proposes, in the application scenarios of reality, also can after each the triggering, only carry out one-shot measurement, and obtain The ultimate results, compare with cycle detection scheme based on the cycle, can there be certain shortcoming in such processing scheme on accuracy in detection, but the resource that can a large amount of savings is used to detect, shorten the time of detecting, improve the efficient that detects.
In the application scenarios of reality, can be according to the definite scheme that is adopted of concrete needs, such variation does not influence protection scope of the present invention.
The optical fiber state of the pairing optical fiber of corresponding optical fiber interface is determined according to the relevant detection result in step S102, base station.
At first, no matter adopt which kind of detection scheme, the core of the technical scheme that the embodiment of the invention proposed all is to determine according to the luminous power of optical fiber interface and optical fiber interface status detection result the optical fiber state of corresponding optical fiber, and concrete detection rule is as follows:
Be lower than default optical power threshold if detect the luminous power of optical fiber interface, and/or the optical fiber interface state is step-out, then the base station determines that the optical fiber state of the pairing optical fiber of this optical fiber interface is a fault.
Be not lower than default optical power threshold if detect the luminous power of optical fiber interface, and the optical fiber interface state is synchronously, then the base station determines that the optical fiber state of the pairing optical fiber of this optical fiber interface is for normal.
Wherein, whether the power loss that optical power threshold is mainly used to weigh in the optical fiber transmission signal process meets the requirements, in the luminous power of the signal of initialization under the constant or sufficiently high situation of initial light power, if the actual light power of the signal that the base station receives is higher than default optical power threshold, the luminous power of then representing the institute's loss in the process of this signal of transmission of this optical fiber is lower than the tolerable maximum loss amount of current system, and promptly the power loss of this optical fiber meets the demands.
By above-mentioned detection rule as can be seen, in the technical scheme that the embodiment of the invention proposed, only the power loss at optical fiber is enough little, and under the situation of optical fiber interface state synchronized, the state that could determine this optical fiber is normal, otherwise, no matter be that power loss is too high, still signal transmits step-out, and the optical fiber state of corresponding optical fiber is fault.
Further, if adopt aforesaid cycle detection scheme based on the cycle, so, in an optical fiber state-detection cycle, the base station is according to the relevant detection result, determine also to comprise the process of further single testing result cumulative statistics after the optical fiber state of the pairing optical fiber of corresponding optical fiber interface, specify as follows:
At first, the base station judges whether this optical fiber state-detection result of the pairing optical fiber of each optical fiber interface is consistent with a preceding optical fiber state-detection result.
If judged result is not for, the base station is to the count value zero clearing of the optical fiber state counter of the pairing optical fiber of this optical fiber interface, and according to the optical fiber state information of the pairing optical fiber of this optical fiber state-detection outcome record optical fiber interface.
On the contrary, if judged result is for being that the base station adds 1 to the count value of the optical fiber state counter of the pairing optical fiber of this optical fiber interface.
Further, carry out count value add 1 handle after, the base station judges whether the current count value of this optical fiber state counter reaches default detection frequency threshold value.
If judged result is not for reaching, the cycle detection condition that reaches default is determined in the base station, returns step S101, continues respectively corresponding optical fiber interface to be detected, and promptly proceeds the cycle detection operation in the same optical fiber state-detection cycle.
And if judged result is for reaching, the result of detection who then represents continuous several times is consistent, can determine that current testing result is the actual fiber state of the pairing optical fiber of this optical fiber interface, therefore, the base station is to the count value zero clearing of the pairing optical fiber state counter of optical fiber interface, and with the testing result of the current record current optical fiber state as corresponding optical fiber.
When main fiber under the corresponding load sharing pattern of each optical fiber interface difference that the base station is detected and auxilliary optical fiber, in time carry out corresponding resource distribution adjustment when changing for the optical fiber state at optical fiber, the base station can also come in the following manner further to determine whether the optical fiber state of optical fiber variation has taken place.
In the technical scheme that the embodiment of the invention proposed, concrete judgment mode is by optical fiber state-detection result and this optical fiber the optical fiber state-detection result during preceding optical fiber state-detection cycle of optical fiber in this optical fiber state-detection cycle compared and obtain, and concrete deterministic process and subsequent treatment are described as follows:
After the base station judged that a current count value of the pairing optical fiber state counter of optical fiber interface reaches default detection frequency threshold value, the base station judged whether the optical fiber state information (i.e. the optical fiber state-detection result of the pairing optical fiber of this optical fiber interface in this optical fiber state-detection cycle) of the pairing optical fiber of this optical fiber interface of current record is consistent with the optical fiber state information of the pairing optical fiber of determined this optical fiber interface of previous optical fiber state-detection cycle.
If judged result represents then that for being the optical fiber state of the pairing optical fiber of this optical fiber interface does not change, the detecting operation of this optical fiber interface in the current optical fiber state-detection cycle directly finished in the base station.
If judged result is for denying, change has taken place in the optical fiber state of then representing the pairing optical fiber of this optical fiber interface, the optical fiber state of the pairing optical fiber of optical fiber interface in the current optical fiber state-detection cycle is determined according to the optical fiber state information of the pairing optical fiber of optical fiber interface of current record in the base station, and finishes the detecting operation of optical fiber interface in the current optical fiber state-detection cycle.

(2) if the base station determines that the optical fiber state of auxilliary optical fiber is a fault, and the optical fiber state of main fiber be normal, and the base station keeps fiber resource current in main fiber and the auxilliary optical fiber to dispose.
This kind situation is the processing mode of auxilliary fiber failure when not recovering.
(3) if it is fault that the optical fiber state of main fiber is determined in the base station, and the optical fiber state of auxilliary optical fiber is normal, and the sub-district that disposed on the main fiber is recovered in the base station on auxilliary optical fiber, and assists optical fiber and be set to main fiber.
This kind situation is auxilliary fiber failure and recovers, and the processing mode of main fiber when breaking down, and after finishing above-mentioned processing, former main fiber is stopped using, and former auxilliary optical fiber becomes main fiber.
(4) be fault if the optical fiber state of main fiber and auxilliary optical fiber is determined in the base station, handle again after the opposite equip. that the base station waits main fiber is connected with auxilliary optical fiber withdraws from service.
This kind situation is auxilliary fiber failure and does not recover, and the processing mode of main fiber when breaking down.
Situation three, base station determine that in previous optical fiber state-detection process the optical fiber state of main fiber and auxilliary optical fiber is fault.
In such cases, according to the testing result in this optical fiber state-detection cycle, corresponding processing mode is as follows:
If the optical fiber state of main fiber and auxilliary optical fiber is determined and is normally that the base station is recovered the sub-district to be recovered of current existence respectively on main fiber and auxilliary optical fiber in the base station.
Processing mode when the fault that this kind situation is main fiber and auxilliary optical fiber is all recovered.
By above-mentioned declarative procedure as can be seen, concrete optical fiber state-detection and troubleshooting and recovery are handled and are all finished by the base station, and the base station need be carried out the adjustment of corresponding resource distribution according to the variation of the optical fiber state of optical fiber, opposite equip. only needs to carry out corresponding signal transmission according to corresponding resource distribution and gets final product, and does not need to participate in aforesaid optical fiber state-detection and operations such as troubleshooting and recovery processing.
By above-mentioned processing procedure, can under the situation that the personnel that need not participate in, carry out automatic troubleshooting and recovery, save human cost.
It is pointed out that above-mentioned optical power threshold, optical fiber state-detection cycle and detect frequency threshold value all can in management station, be provided with that concrete set-up mode can not influence protection scope of the present invention.
