The main body of the PON value-added application is a PON network, the PON network belongs to a passive optical network, a point-to-multipoint optical fiber access technology is adopted, the PON value-added application is a bearing network for optical fiber home entry, the quality of the PON optical network is greatly dependent on whether a link optical fiber channel is smooth or not, the optical signal strength is normal or not, and if an optical link is abnormal, performance data deviate from a normal range to generate corresponding abnormal information. Among all PON device anomaly information, weak light information is common anomaly information with a large influence on users, however, current PON value-added applications only stay on the display layer for PON link-related anomaly information such as weak light, and an effective active analysis mechanism is not formed yet, so that after problems such as weak light of an optical link occur, the processing cannot be performed in time, and timeliness of operation and maintenance is affected.
In addition, when PON link is in weak light in the existing network, since the optical link passes through a plurality of nodes, different node management belongs to different operation and maintenance departments, if only weak light abnormality is found, but the problem of determining which section occurs is not solved, it is difficult to dispatch operation and maintenance personnel in time to maintain, and great value cannot be created for clients.

[ detailed description ] of the invention
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Example 1:
the embodiment provides a PON link weak light fault delimiting system, as shown in fig. 2, including an equipment interaction module, an information analysis module, a data storage module and a result display module, where the equipment interaction module is responsible for establishing a communication channel between the system and a local side device, performing equipment management work, receiving abnormal information when a weak light problem occurs in the device, and storing the abnormal information in the data storage module to form an abnormal information queue; the information analysis module is in charge of acquiring abnormal information in an abnormal information queue in the data storage module at intervals, analyzing the acquired abnormal information to obtain a delimitation result, and storing the delimitation result in the data storage module; the data storage module is used for storing the abnormal information reported by the equipment interaction module, the delimited result and the topology information obtained by the information analysis module; the result display module is responsible for receiving a request for viewing by a user and graphically displaying the delimited results in the data storage module on a user interface for viewing by the user.
Example 2:
the embodiment 1 of the present invention also provides a PON link weak light fault defining method, as shown in fig. 1, including:
step 10, obtaining abnormal information and clustering the abnormal information meeting the screening rule;
after the communication channel is established between the equipment interaction module and the local side equipment, the abnormal information reported by the local side equipment is stored into the data storage module to form an abnormal information queue, and the information analysis module acquires the abnormal information from the abnormal information queue of the data storage module at intervals, wherein the abnormal information in the abnormal information queue of the data storage module is cleared from the abnormal information queue of the data storage module after being analyzed and delimited by the information analysis module. After the information analysis module acquires the abnormal information in the abnormal information queue of the data storage module, the acquired abnormal information is screened according to screening rules, and then the abnormal information meeting the screening rules is clustered, wherein the specific clustering mode is as follows: abnormal information under the PON port of the same local side is gathered into one type.
The embodiment provides a mode which can be realized in an actual scene, which is specifically as follows:
assuming that the information analysis module obtains the abnormal information in the abnormal information queue from the data storage module every 1min, 30 pieces of abnormal information are obtained from the abnormal information queue of the data storage module at the current moment, and the 30 pieces of abnormal information are screened according to a screening rule, for example: the screening rules are as follows: if the anomaly information is not disappeared within 1min, the screening rule is satisfied, and the purpose of this step is mainly to filter out the random burst anomalies and anomalies that can be repaired by oneself, such as: the child can connect and disconnect the remote device all the time in order to greet, and the specific screening rule can be set according to the needs by oneself, and the screening rule is not limited here. If all 30 pieces of abnormal information meet the screening rule, clustering the abnormal information meeting the screening rule, specifically, clustering the abnormal information under the same local side PON port, and if all 30 pieces of abnormal information come from equipment under the same local side PON port A, clustering the 30 pieces of abnormal information into one type (namely, the abnormal information under the same clustering result). And judging whether the abnormal information under the same clustering result contains abnormal information of the fault of the local side PON port optical module, and if the abnormal information under the same clustering result contains abnormal information of the fault of the local side PON port optical module, determining that the boundary result is the fault of the local side PON port optical module. Since the far-end equipment connected down to the local PON port optical module is affected when the local PON port optical module fails, the demarcation result is a local PON port optical module failure (i.e., an optical module failure at the local PON port a).
Step 20, if the abnormal information under the same clustering result is judged to not contain the abnormal information of the fault of the local side PON port optical module, judging whether the abnormal information under the same clustering result is from a single remote device;
the embodiment provides a mode which can be realized in an actual scene, which is specifically as follows:
assuming that 30 pieces of abnormality information reported by equipment at the local side PON port A do not contain abnormality information of the fault of the local side PON port optical module, judging whether the 30 pieces of abnormality information come from a single remote equipment or not.
If the 30 pieces of abnormal information are judged to be from a plurality of remote devices, judging the ratio of the number of the plurality of remote devices generating the 30 pieces of abnormal information to the number of all remote devices under the same local side PON port A connected with the plurality of remote devices generating the 30 pieces of abnormal information, and judging whether the ratio exceeds a first preset value or not; if the ratio exceeds a first preset value, the delimiting result is a main light path fault; if the ratio does not exceed the first preset value, the boundary result is a branch light path fault.
In this embodiment, a PON link includes two optical splitters as an example, as shown in fig. 3-4, it is assumed that a first-stage optical splitter is connected to a downstream side PON port a, and two second-stage optical splitters are connected to the downstream side PON port a, where each of the two second-stage optical splitters is connected to 5 downstream devices, then 10 downstream devices are connected to the downstream side PON port a, assuming that the 30 pieces of abnormal information are generated by 8 downstream devices, a ratio of the number 8 of the plurality of downstream devices that generate the 30 pieces of abnormal information to the number 10 of all downstream devices under the downstream side PON port a connected to the plurality of downstream devices that generate the 30 pieces of abnormal information is 0.8, assuming that the first preset value is 0.7, and since the ratio 0.8 exceeds the first preset value by 0.7, the delimiting result is a trunk optical path failure; assuming that the 30 pieces of abnormal information are generated by 3 pieces of remote equipment, the ratio of the number 3 of the plurality of remote equipment generating the 30 pieces of abnormal information to the number 10 of all the remote equipment under the local side PON port a connected to the plurality of remote equipment generating the 30 pieces of abnormal information is 0.3, assuming that the first preset value is 0.7, since the ratio 0.3 does not exceed the first preset value by 0.7, the delimiting result is a branch optical path fault, and then according to the topology information, which branch optical path fault is obtained. Because the PON link is a passive optical network, only the remote device and the local device can report abnormal information, the relationship between the remote device and the optical splitter needs to be obtained by means of topology information, specifically, the topology information is recorded in a link connection condition between the optical splitter and the remote device, the obtaining mode of the PON link may be that an operation and maintenance person records node information when opening a service, and then the node information is manually recorded in a data storage module of the PON link system, or the PON link can be obtained by reversely associating the abnormal information of the remote device with the abnormal information of the local device according to an algorithm, which is not limited herein. The first preset value in the present embodiment can be set according to the actual requirement, and the setting of the first preset value in the present embodiment is merely illustrative.
Step 30, if it is determined that the abnormal information under the same clustering result is from a single remote device, and the average value of the optical power performance of other remote devices under the same optical splitter connected to the single remote device generating the abnormal information is not within the warning threshold range, determining whether the abnormal information generated by the single remote device is abnormal information of a fault of a remote PON port optical module;
if it is determined that the 30 pieces of abnormality information come from a single remote device, which is the remote device 1, the case may be divided into the following two cases:
(1) The real all-link of the local side PON port A has only one abnormal far-end equipment
(2) The all-link under the local side PON port A shows that only one far-end device is abnormal, and the optical power performance indexes of a plurality of far-end devices under the same optical splitter connected with the actual far-end device 1 are very close to a threshold value, but do not reach the threshold value yet, so that only abnormal information sent by one far-end device can be received;
the average value of the optical power performance is specifically: and acquiring optical power performance values of other remote devices under the same optical splitter connected with the single remote device generating abnormal information according to the topology information, and calculating an average value to obtain an optical power performance average value.
The method comprises the following steps: and acquiring the optical power performance values of other 4 remote devices under the same optical splitter (namely the same primary optical splitter and the same secondary optical splitter) connected with the remote device 1 according to the topology information, and calculating the average value of the optical power performance values of the other 4 remote devices under the same optical splitter connected with the remote device 1 to obtain the optical power performance average value. Assuming that the average value of the optical power performance is-20.5 dBm, the alert threshold range is (-24, -23.7), it is known that-20.5 dBm is not in the alert threshold range, which means that the full link under the PON port a of the office end is truly only abnormal for one far-end device 1, where-24 in the alert threshold range is a threshold value, -23.7 is a maximum alert value, and the maximum alert value is close to the threshold value, where the maximum alert value and the threshold value can be set by themselves according to the requirement, and this embodiment is merely illustrative and not intended to limit the present invention. The optical power performance value according to the present embodiment includes one or more of an optical power value, an optical attenuation value, a bias current value, and a voltage value.
Assuming that the average value of the optical power performance is-23.8 dBm, the warning threshold range is (-24, -23.7), and it is known that-23.8 dBm is within the warning threshold range, the boundary result is that the branch optical path is abnormal, and then according to the topology information, which branch optical path is faulty is obtained.
Step 40, if the abnormal information generated by the single remote device is judged to be abnormal information of the non-remote PON port optical module fault and the optical power performance value of the single remote device generating the abnormal information is not within a normal threshold range, the delimiting result is a networking fault, and the delimiting result is graphically displayed on a user interface for a user to view.
Judging whether the abnormal information generated by the remote equipment 1 is abnormal information of a remote PON port optical module fault or not after judging that only one remote equipment 1 is actually abnormal in the full link under the local PON port A;
if the abnormal information generated by the single remote equipment is judged to be the abnormal information of the fault of the remote PON port optical module, the delimiting result is the fault of the remote PON port optical module. The method comprises the following steps: if the abnormal information generated by the remote device 1 is judged to be the abnormal information of the remote PON port optical module fault, the delimiting result is the remote PON port optical module fault (i.e., the PON port optical module fault of the remote device 1); if the abnormal information generated by the remote device 1 is judged to be abnormal information of a non-remote PON port optical module fault, it is judged whether the optical power performance value of the remote device 1 generating the abnormal information is within a normal threshold range, where the normal threshold range may be set according to historical experience, or may be calculated according to the current environment itself, and the present invention is not limited. If the normal threshold range is calculated according to the current environment, the following calculation method is exemplified: acquiring optical power performance values of other 9 remote devices under the local side PON port A connected with the remote device 1, counting the maximum value Vmax and the minimum value Vmin of the optical power performance values, calculating according to the Vmax, the Vmin and an abnormal threshold value to obtain a normal threshold range, assuming that the abnormal threshold value is Te, the normal threshold range is (Vmin-Te, vmax+Te), and calculating to obtain that the normal threshold range is (-23.3-2 dBm, -19.5+2 dBm) if the Vmax is-19.5 dBm, the Vmin is-23.3 dBm and the Te is 2dBm in the optical power performance values of other 9 remote devices under the local side PON port A connected with the remote device 1; assuming that the optical power performance value of the remote device 1 generating the anomaly information is-30 dBm, it is known that the optical power performance value of the remote device 1 is-30 dBm which is not within the normal threshold range (-23.3-2 dBm, -19.5+2dbm), and the delimiting result is a networking fault, in this embodiment Vmax is-19.5 dBm, vmin is-23.3 dBm and Te is 2dBm are merely illustrative, and are not intended to limit the present invention;
if the optical power performance value of the single remote equipment generating the abnormal information is within the normal threshold range, the demarcation result is that the fiber to the home is abnormal.
Assuming that the optical power performance value of the remote device 1 generating the anomaly information is-20 dBm, it is known that the optical power performance value of the remote device 1 is-20 dBm within the normal threshold range (-23.3-2 dBm, -19.5+2dbm), and the demarcation result is that the fiber to the home is anomalous.
And storing the delimited results obtained by the information analysis module in the data storage module, receiving a request for viewing by a user by the result display module, and graphically displaying the delimited results in the data storage module on a user interface for viewing by the user.
As shown in fig. 6, step 201 further includes, if it is determined that the abnormality information in the same clustering result does not include abnormality information of the fault of the PON port optical module at the office end, and it is determined that the abnormality information in the same clustering result is from a plurality of remote devices;
assuming that 30 pieces of abnormal information reported by equipment under a local side PON port A do not contain abnormal information of a fault of a local side PON port optical module, and judging that the 30 pieces of abnormal information come from a plurality of remote equipment;
step 202, calculating the ratio of the number of the plurality of remote devices generating the abnormal information to the number of all the remote devices under the same local side PON port to which the plurality of remote devices generating the abnormal information are connected;
the method comprises the following steps: the ratio of the number of the plurality of remote devices generating the 30 pieces of abnormal information to the number of all the remote devices under the same local side PON port a connected to the plurality of remote devices generating the 30 pieces of abnormal information is to be determined, in this embodiment, a PON link is described by taking a second optical splitter as an example, and it is assumed that a first-stage optical splitter is connected to the local side PON port a, and two second-stage optical splitters are connected to the first-stage optical splitter, where each second-stage optical splitter is connected to 5 remote devices, then 10 remote devices are connected to the local side PON port a.
Step 203, judging whether the ratio exceeds a first preset value;
step 204, if the ratio exceeds a first preset value, the delimiting result is a main light path fault;
assuming that the 30 pieces of abnormal information are generated by 8 pieces of remote equipment, the ratio of the number 8 of the plurality of remote equipment generating the 30 pieces of abnormal information to the number 10 of all the remote equipment under the local side PON port a connected up to the plurality of remote equipment generating the 30 pieces of abnormal information is calculated to be 0.8, assuming that the first preset value is 0.7, and since the ratio 0.8 exceeds the first preset value by 0.7, the delimiting result is a trunk optical path failure.
In step 205, if the ratio does not exceed the first preset value, the delimiting result is a branch optical path fault.
Assuming that the 30 pieces of abnormal information are generated by 3 pieces of remote equipment, the ratio of the number 3 of the plurality of remote equipment generating the 30 pieces of abnormal information to the number 10 of all the remote equipment under the local side PON port a connected to the plurality of remote equipment generating the 30 pieces of abnormal information is 0.3, assuming that the first preset value is 0.7, since the ratio 0.3 does not exceed the first preset value by 0.7, the delimiting result is a branch optical path fault, and then according to the topology information, which branch optical path fault is obtained. Because the PON link is a passive optical network, only the remote device and the local device can report abnormal information, the relationship between the remote device and the optical splitter needs to be obtained by means of topology information, specifically, the topology information is recorded in a link connection condition between the optical splitter and the remote device, the obtaining mode of the PON link may be that an operation and maintenance person records node information when opening a service, and then the node information is manually recorded in a data storage module of the PON link system, or the PON link can be obtained by reversely associating the abnormal information of the remote device with the abnormal information of the local device according to an algorithm, which is not limited herein. The first preset value in the present embodiment can be set according to the actual requirement, and the setting of the first preset value in the present embodiment is merely illustrative.
And if the abnormal information under the same clustering result is judged to come from a single remote device, and the average value of the optical power performance of other remote devices under the same optical splitter connected with the single remote device generating the abnormal information is within the warning threshold range, the boundary result is a branch optical path fault.
And acquiring the optical power performance values of other 4 remote devices under the same optical splitter (namely the same primary optical splitter and the same secondary optical splitter) connected with the remote device 1 according to the topology information, and calculating the average value of the optical power performance values of the other 4 remote devices under the same optical splitter connected with the remote device 1 to obtain the optical power performance average value. Assuming that the average value of the optical power performance is-23.7 dBm, the warning threshold range is (-24, -23.5), the fact that-23.7 dBm is within the warning threshold range indicates that the average value of the optical power performance of other 4 remote devices under the same optical splitter connected with the single remote device 1 generating abnormal information reaches the warning condition, the delimiting result is that the branch optical path is abnormal at the moment, and then according to the topology information, which branch optical path is faulty is obtained.
The normal threshold range is specifically:
acquiring optical power performance values of other remote devices under a local side PON port connected with a single remote device generating abnormal information; the method comprises the following steps: and acquiring the optical power performance values of other 9 pieces of far-end equipment under the local side PON port A connected with the far-end equipment 1, and counting the maximum value Vmax and the minimum value Vmin of the optical power performance values.
And calculating the normal threshold range according to the optical power performance values and the abnormal threshold values of other remote devices under the local side PON port connected with the single remote device generating the abnormal information. The method comprises the following steps: and calculating the normal threshold range according to Vmax, vmin and an abnormal threshold value, and assuming that the abnormal threshold value is Te, the normal threshold range is (Vmin-Te, vmax+Te). The present embodiment is merely illustrative of a case where a normal threshold range is calculated, and the normal threshold range may be set based on history experience.
The above is the complete process of the PON link weak light fault demarcation method provided by the embodiment of the present invention, where a specific flow of PON link weak light fault demarcation may refer to fig. 7, and all cases of PON link weak light fault demarcation are shown in fig. 5.

The embodiment further provides a method for delimiting a PON link from a weak light fault on the basis of embodiment 1, as shown in fig. 8, where the PON link in this embodiment only includes a first-stage optical splitter and does not include a second-stage optical splitter; it is assumed that a first-level optical splitter is connected to the lower part of the local-end PON port a, and 10 remote devices are connected to the lower part of the first-level optical splitter.
Acquiring abnormal information and clustering the abnormal information meeting the screening rule;
assuming that the information analysis module obtains the abnormal information in the abnormal information queue from the data storage module every 1min, 30 pieces of abnormal information are obtained from the abnormal information queue of the data storage module at the current moment, and the 30 pieces of abnormal information are screened according to a screening rule, for example: the screening rules are as follows: if the anomaly information is not disappeared within 1min, the screening rule is satisfied, and the purpose of this step is mainly to filter out the random burst anomalies and anomalies that can be repaired by oneself, such as: the child can connect and disconnect the remote device all the time in order to greet, and the specific screening rule can be set according to the needs by oneself, and the screening rule is not limited here. If all 30 pieces of abnormal information meet the screening rule, clustering the abnormal information meeting the screening rule, specifically, clustering the abnormal information under the same local side PON port, and if all 30 pieces of abnormal information come from equipment under the same local side PON port A, clustering the 30 pieces of abnormal information into one type (namely, the abnormal information under the same clustering result). And judging whether the abnormal information under the same clustering result contains abnormal information of the fault of the local side PON port optical module, and if the abnormal information under the same clustering result contains abnormal information of the fault of the local side PON port optical module, determining that the boundary result is the fault of the local side PON port optical module. Since if the local PON port optical module fails, all the far-end devices connected down to the local PON port optical module are affected, and the delimiting result is that the local PON port optical module fails (i.e., the optical module of the local PON port a fails).
If the abnormal information under the same clustering result is judged to not contain the abnormal information of the fault of the local side PON port optical module, judging whether the abnormal information under the same clustering result comes from a single remote device or not;
if the 30 pieces of abnormal information are judged to come from a plurality of remote devices, the delimiting result is a main light path fault;
judging whether the abnormal information generated by the single remote equipment is abnormal information of a remote PON port optical module fault or not if the abnormal information generated by the same clustering result is from the single remote equipment and the average value of the optical power performance of other remote equipment of the same optical splitter connected with the single remote equipment generating the abnormal information is not in the warning threshold range;
if it is determined that the 30 pieces of abnormality information come from a single remote device, which is marked as the remote device 1, the case may be divided into the following two cases:
(1) The real only one far-end equipment of the full link under the PON port A of the local side is abnormal;
(2) The full link under the PON port a at the local side shows that only one far-end device is abnormal, and the optical power performance indexes of a plurality of far-end devices under the same optical splitter (here, the first-stage optical splitter connected to the far-end device 1) connected to the far-end device 1 are very close to the threshold value, but do not reach the threshold value yet, so that only abnormal information sent by one far-end device can be received.
And acquiring the optical power performance values of other 9 remote devices under the same optical splitter (namely a primary optical splitter) connected with the remote device 1 according to the topology information, and calculating the average value of the optical power performance values of the other 9 remote devices under the same optical splitter connected with the remote device 1 to obtain an optical power performance average value.
Assuming that the average value of the optical power performance is-20.5 dBm, the alert threshold range is (-24, -23.7), it is known that-20.5 dBm is not in the alert threshold range, which means that the full link under the PON port a of the office end is truly only abnormal for one far-end device 1, where-24 in the alert threshold range is a threshold value, -23.7 is a maximum alert value, and the maximum alert value is close to the threshold value, where the maximum alert value and the threshold value can be set by themselves according to the requirement, and this embodiment is merely illustrative and not intended to limit the present invention. If only one remote device 1 is actually abnormal under the local side PON port A, judging whether the abnormal information generated by the remote device 1 is abnormal information of a remote PON port optical module fault or not; if the abnormal information generated by the remote device 1 is judged to be the abnormal information of the remote PON port optical module fault, the delimiting result is the remote PON port optical module fault (i.e., the PON port optical module fault of the remote device 1); assuming that the average value of the optical power performance is-23.8 dBm, the warning threshold range is (-24, -23.7), and the fact that-23.8 dBm is within the warning threshold range is known, the boundary result is a main light path fault.
Judging that the abnormal information generated by the single remote equipment is abnormal information of a non-remote PON port optical module fault, and if the optical power performance value of the single remote equipment generating the abnormal information is not in a normal threshold range, the delimiting result is a networking fault, and displaying the delimiting result in a graphical manner on a user interface for a user to check.
If the abnormal information generated by the remote device 1 is abnormal information of a non-remote PON port optical module fault, determining whether an optical power performance value of the remote device 1 generating the abnormal information is within a normal threshold range, specifically, acquiring optical power performance values of other 9 remote devices under the local PON port a connected to the remote device 1, counting a maximum value Vmax and a minimum value Vmin of the optical power performance values, calculating to obtain the normal threshold range according to the Vmax, the Vmin and an abnormal threshold value, assuming that the abnormal threshold value is Te, the normal threshold range is (Vmin-Te, vmax+te), and if the statistics obtains that Vmax is-19.5 dBm, vmin is-23.3 dBm, and assuming that Te is 2dBm in the optical power performance values of other 9 remote devices under the local PON port a connected to the remote device 1, calculating to obtain the normal threshold range is (-23.3-2 dBm, -19.5+2dbm); assuming that the optical power performance value of the remote device 1 generating the abnormal information is-30 dBm, it is known that the optical power performance value of the remote device 1 is-30 dBm which is not within the normal threshold range (-23.3-2 dBm, -19.5+2dbm), and the delimiting result is a networking fault; if the optical power performance value of the single remote equipment generating the abnormal information is within the normal threshold range, the demarcation result is that the fiber to the home is abnormal. Assuming that the optical power performance value of the remote device 1 generating the anomaly information is-20 dBm, it is known that the optical power performance value of the remote device 1 is-20 dBm within the normal threshold range (-23.3-2 dBm, -19.5+2dbm), and the delimiting result is that the fiber to be added is abnormal, the Vmax is-19.5 dBm, the vmin is-23.3 dBm, and the Te is 2dBm are merely illustrative, and are not intended to limit the present invention.
And storing the delimited results obtained by the information analysis module in the data storage module, receiving a request for viewing by a user by the result display module, and graphically displaying the delimited results in the data storage module on a user interface for viewing by the user. The present examples are intended to be illustrative only and are not intended to be limiting.
