In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1:
the embodiment provides a PON link weak light fault delimiting system, which, as shown in fig. 2, includes 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 device 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 responsible for acquiring abnormal information in an abnormal information queue in the data storage module at intervals, analyzing the acquired abnormal information to obtain a delimiting result and storing the delimiting result in the data storage module; the data storage module is responsible for storing abnormal information reported by the equipment interaction module, and delimitation results and 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 result in the data storage module on a user interface for the user to view.
Example 2:
embodiment 1 of the present invention further provides a PON link weak light fault delimiting method, as shown in fig. 1, including:
after the device interaction module and the local side device establish a communication channel, the abnormal information reported by the local side device is stored in 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 the screening rule, and then the abnormal information meeting the screening rule is clustered, wherein the specific clustering mode is as follows: and gathering abnormal information under the same local side PON port into one type.
The embodiment provides a mode that can be realized in an actual scene, specifically:
assuming that the information analysis module acquires the abnormal information in the abnormal information queue from the data storage module every 1min, acquiring 30 pieces of abnormal information from the abnormal information queue of the data storage module at the current moment, and screening the 30 pieces of abnormal information according to a screening rule, for example: the screening rule is as follows: the abnormal information which does not disappear in 1min meets the screening rule, and the purpose of the step is mainly to filter out the sudden abnormal and the abnormal which can be repaired by self, such as: the children can plug and pull the remote equipment all the time in order to greet, and the setting of specific screening rule can be set by oneself according to the demand, and here, do not restrict the screening rule. Assuming that all the 30 pieces of abnormal information satisfy the screening rule, clustering the abnormal information satisfying the screening rule, specifically, clustering the abnormal information under the same office-side PON port into one class, and assuming that all the 30 pieces of abnormal information are from the device under the same office-side PON port a, clustering the 30 pieces of abnormal information into one class (i.e., the abnormal information under the same clustering result). And then judging whether the abnormal information under the same clustering result contains the abnormal information of the optical module fault of the local side PON port, and if the abnormal information under the same clustering result contains the abnormal information of the optical module fault of the local side PON port, delimiting the result as the optical module fault of the local side PON port. If the optical module at the office port PON fails, the remote device connected to the optical module at the office port PON is affected, so the delimiting result is an optical module failure at the office port PON (i.e., an optical module failure at the office port PON).
the embodiment provides a mode that can be realized in an actual scene, specifically:
if the 30 pieces of abnormal information reported by the device under the central office PON port a do not contain abnormal information of the fault of the optical module of the central office PON port, it is determined whether the 30 pieces of abnormal information are from a single remote device.
If the 30 pieces of abnormal information are judged to be from a plurality of remote devices, 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 central office PON port a connected to the plurality of remote devices generating the 30 pieces of abnormal information needs to be judged, and whether the ratio exceeds a first preset value is judged; if the ratio exceeds a first preset value, the delimiting result is a main light path fault; and if the ratio does not exceed the first preset value, the delimiting result is a branch light path fault.
In this embodiment, a PON link is described by taking a secondary optical splitter as an example, as shown in fig. 3-4, assuming that a primary optical splitter is connected below a local PON port a, and two secondary optical splitters are connected below the primary optical splitter, where each secondary optical splitter is connected below 5 remote devices, then the local PON port a is connected below 10 remote devices, assuming that the 30 pieces of abnormal information are generated by 8 remote devices, a ratio between 8 of the number 8 of the remote devices generating the 30 pieces of abnormal information and 10 of all the remote devices below the local PON port a connected above the remote devices generating the 30 pieces of abnormal information is calculated to be 0.8, assuming that a first preset value is 0.7, and since the ratio 0.8 exceeds the first preset value 0.7, a delimiting result is a trunk optical path fault; assuming that the 30 pieces of abnormal information are generated by 3 pieces of remote devices, a ratio of the number 3 of the multiple remote devices generating the 30 pieces of abnormal information to the number 10 of all the remote devices under the central office PON port a of the uplink multiple remote devices generating the 30 pieces of abnormal information may be calculated to be 0.3, assuming that the first preset value is 0.7, since the ratio 0.3 does not exceed the first preset value 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. The PON link is a passive optical network, only the remote device and the local device may report the abnormal information, and the relationship between the remote device and the optical splitter needs to be obtained by using topology information, specifically, the topology information records the link connection condition between the optical splitter and the remote device, and the obtaining method may be that an operation and maintenance worker records node information when opening a service, and then manually records the node information into a data storage module of the system, or performs reverse association by using the correlation between the abnormal information of the remote device and the abnormal information of the local device according to an algorithm, which is not limited herein. The first preset value in this embodiment can be set according to actual requirements, and the setting of the first preset value in this embodiment is only an example.
if the 30 pieces of abnormal information are judged to be from a single remote device, which is the remote device 1, the situation can be divided into the following two situations:
(1) the fact that the whole link under the local side PON port A is only provided with one remote end device is abnormal
(2) The full link at the port a of the local side PON shows that only one remote device is abnormal, and the optical power performance indexes of a plurality of remote devices under the same optical splitter connected to the remote device 1 are very close to the threshold value, but do not reach the threshold value, so that only abnormal information sent by one remote device can be received;
the average value of the optical power performance specifically comprises: and acquiring the optical power performance values of other remote equipment under the same optical splitter connected to the single remote equipment which generates the abnormal information according to the topological information, and calculating the average value to obtain the optical power performance average value.
The method specifically comprises the following steps: and acquiring 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 to the remote device 1 according to the topology information, and calculating an average value of the optical power performance values of other 4 remote devices under the same optical splitter connected to the remote device 1 to obtain an optical power performance average value. Assuming that the calculated optical power performance average value is-20.5 dBm, and the alarm threshold range is (-24, -23.7), it can be known that-20.5 dBm is not within the alarm threshold range, which means that the full link under the central PON port a is really only one remote device 1 abnormal, where-24 in the alarm threshold range is a threshold value, -23.7 is a maximum alarm value, which is close to the threshold value, and where the maximum alarm value and the threshold value may be set by themselves according to requirements, this embodiment is merely an example and is not used 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 calculated optical power performance average value is-23.8 dBm, the warning threshold range is-24, -23.7, and knowing that-23.8 dBm is within the warning threshold range, the delimitation result is that the branch optical path is abnormal, and then according to the topology information, which branch optical path is in fault is obtained.
And step 40, if the abnormal information generated by the single remote equipment is judged to be the abnormal information of the fault of the non-remote PON port optical module, and the optical power performance value of the single remote equipment generating the abnormal information is not in the normal threshold range, the delimiting result is the networking fault, and the delimiting result is graphically displayed on a user interface for the user to check.
Judging whether the all-link of the local side PON port A is really only one remote device 1 abnormal or not, and judging whether the abnormal information generated by the remote device 1 is the abnormal information of the fault of the remote PON port optical module or not;
and if the abnormal information generated by the single remote device 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 specifically comprises the following steps: if the abnormal information generated by the remote device 1 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 (namely the fault of the PON port optical module of the remote device 1); if the abnormal information generated by the remote device 1 is judged to be the abnormal information of the non-remote PON interface 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 calculated according to the current environment, and the present invention is not limited. If the normal threshold range is calculated according to the current environment itself, the calculation method is as follows: acquiring optical power performance values of other 9 remote devices under an office 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 a 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 optical power performance values of the other 9 remote devices under the office PON port A connected to the remote device 1 are counted to obtain Vmax of-19.5 dBm, Vmin of-23.3 dBm, and assuming that Te is 2dBm, calculating to obtain the normal threshold range of (-23.3-2dBm, -19.5+2 dBm); 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 and is not within the normal threshold range (-23.3-2dBm, -19.5+2dBm), the delimiting result is a networking fault, in this embodiment, Vmax is-19.5 dBm, Vmin is-23.3 dBm, and Te is 2dBm, which is only for illustration and is not used to limit the present invention;
and if the optical power performance value of the single remote device generating the abnormal information is within the normal threshold range, the delimiting result is that the fiber to the home is abnormal.
If the optical power performance value of the remote device 1 generating the abnormal information is-20 dBm, it can be known that the optical power performance value of the remote device 1 is-20 dBm within the normal threshold range (-23.3-2dBm, -19.5+2dBm), and the delimiting result is an optical fiber abnormality entering the home.
And the delimitation result obtained by the information analysis module is stored in the data storage module, the result display module receives a request for viewing by a user, and the delimitation result in the data storage module is graphically displayed on a user interface for the user to view.
As shown in fig. 6, step 201 further includes, if it is determined that the abnormal information in the same clustering result does not include the abnormal information of the fault of the optical module of the local PON port, and it is determined that the abnormal information in the same clustering result comes from multiple remote devices;
supposing that the 30 pieces of abnormal information reported by the equipment under the local side PON port A do not contain the abnormal information of the fault of the optical module of the local side PON port obtained by analysis, and judging that the 30 pieces of abnormal information come from a plurality of remote end equipment;
the method specifically comprises the following steps: it is necessary to determine a ratio between the number of the plurality of remote devices generating the 30 pieces of abnormal information and the number of all the remote devices under the same central office PON port a connected to the plurality of remote devices generating the 30 pieces of abnormal information, in this embodiment, a PON link includes two-stage optical splitters as an example, and assuming that a single-stage optical splitter is connected to the central office PON port a, and two second-stage optical splitters are connected to the single-stage optical splitter, where each second-stage optical splitter connects 5 remote devices to the single-stage optical splitter, then the central office PON port a connects 10 remote devices to the single-stage optical splitter.
assuming that the 30 pieces of abnormal information are generated by 8 pieces of remote devices, a ratio of the number 8 of the plurality of remote devices generating the 30 pieces of abnormal information to the number 10 of all the remote devices under the central office PON port a connected to the plurality of remote devices generating the 30 pieces of abnormal information may be 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 0.7, the delimiting result is a trunk optical path fault.
Assuming that the 30 pieces of abnormal information are generated by 3 pieces of remote devices, a ratio of the number 3 of the multiple remote devices generating the 30 pieces of abnormal information to the number 10 of all the remote devices under the central office PON port a of the uplink multiple remote devices generating the 30 pieces of abnormal information may be calculated to be 0.3, assuming that the first preset value is 0.7, since the ratio 0.3 does not exceed the first preset value 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. The PON link is a passive optical network, only the remote device and the local device may report the abnormal information, and the relationship between the remote device and the optical splitter needs to be obtained by using topology information, specifically, the topology information records the link connection condition between the optical splitter and the remote device, and the obtaining method may be that an operation and maintenance worker records node information when opening a service, and then manually records the node information into a data storage module of the system, or performs reverse association by using the correlation between the abnormal information of the remote device and the abnormal information of the local device according to an algorithm, which is not limited herein. The first preset value in this embodiment can be set according to actual requirements, and the setting of the first preset value in this embodiment is only an example.
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 to the single remote device generating the abnormal information is within the warning threshold range, the delimited result is a branch optical path fault.
And acquiring 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 to the remote device 1 according to the topology information, and calculating an average value of the optical power performance values of other 4 remote devices under the same optical splitter connected to the remote device 1 to obtain an optical power performance average value. Assuming that the calculated optical power performance mean value is-23.7 dBm and the warning threshold range is-24, -23.5, it can be known that-23.7 dBm is in the warning threshold range, which indicates that the optical power performance mean values of other 4 remote devices under the same optical splitter connected to the single remote device 1 generating abnormal information reach the warning condition, and the delimiting result is that the branch optical path is abnormal, and then which branch optical path is failed is obtained according to the topology information.
The normal threshold range specifically includes:
acquiring optical power performance values of other remote equipment below a local side PON port of a single remote equipment upper link generating abnormal information; the method specifically comprises the following steps: the optical power performance values of other 9 remote devices under the central office PON port a of the upper connection of the remote device 1 are obtained, and the maximum value Vmax and the minimum value Vmin of the optical power performance values are counted.
And calculating the normal threshold range according to the optical power performance value and the abnormal threshold value of other remote equipment below the local side PON port of the single remote equipment which generates the abnormal information and is connected with the local side PON port. The method specifically comprises the following steps: and calculating the normal threshold range according to Vmax, Vmin and the abnormal threshold value, and assuming that the abnormal threshold value is Te, the normal threshold range is (Vmin-Te, Vmax + Te). This embodiment is merely to exemplify a case of calculating a normal threshold range, which may also be set based on historical experience.
The above is a complete process of the PON link weak light fault delimitation method provided by the embodiment of the present invention, where a specific flow of the PON link weak light fault delimitation may refer to fig. 7, and all situations of the PON link weak light fault delimitation are as shown in fig. 5.

The present embodiment further provides a PON link weak light fault delimiting method based on embodiment 1, and as shown in fig. 8, the PON link in the present embodiment only includes a first-stage optical splitter and does not include a second-stage optical splitter; suppose that a first-stage optical splitter is connected below the port a of the local side PON, and 10 remote devices are connected below the first-stage optical splitter.
Acquiring abnormal information, and clustering the abnormal information meeting the screening rule;
assuming that the information analysis module acquires the abnormal information in the abnormal information queue from the data storage module every 1min, acquiring 30 pieces of abnormal information from the abnormal information queue of the data storage module at the current moment, and screening the 30 pieces of abnormal information according to a screening rule, for example: the screening rule is as follows: the abnormal information which does not disappear in 1min meets the screening rule, and the purpose of the step is mainly to filter out the sudden abnormal and the abnormal which can be repaired by self, such as: the children can plug and pull the remote equipment all the time in order to greet, and the setting of specific screening rule can be set by oneself according to the demand, and here, do not restrict the screening rule. Assuming that all the 30 pieces of abnormal information satisfy the screening rule, clustering the abnormal information satisfying the screening rule, specifically, clustering the abnormal information under the same office-side PON port into one class, and assuming that all the 30 pieces of abnormal information are from the device under the same office-side PON port a, clustering the 30 pieces of abnormal information into one class (i.e., the abnormal information under the same clustering result). And then judging whether the abnormal information under the same clustering result contains the abnormal information of the optical module fault of the local side PON port, and if the abnormal information under the same clustering result contains the abnormal information of the optical module fault of the local side PON port, delimiting the result as the optical module fault of the local side PON port. If the optical module at the local side PON port fails, the remote device connected to the optical module at the local side PON port is affected, and the delimiting result is an optical module failure at the local side PON port (i.e., an optical module failure at the local side PON port a).
If the abnormal information under the same clustering result does not contain the abnormal information of the fault of the optical module of the local side PON port, 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 under the same clustering result comes 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, and judging whether the abnormal information generated by the single remote device is the abnormal information of the fault of the optical module at the remote PON port;
if the 30 pieces of abnormal information are judged to come from a single remote device, and the single remote device is marked as the remote device 1, the situation can be divided into the following two situations:
(1) the whole link at the port A of the local side PON is really only abnormal by one remote device;
(2) the full link at the central office PON port a shows that only one remote device is abnormal, and the optical power performance indexes of a plurality of remote devices under the same optical splitter (here, the first-stage optical splitter connected to the remote device 1) connected to the remote device 1 are very close to the threshold value, but do not reach the threshold value, so that only abnormal information sent by one remote device can be received.
And acquiring optical power performance values of other 9 pieces of remote equipment under the same optical splitter (namely, a first-stage optical splitter) connected to the remote equipment 1 according to the topology information, and calculating an average value of the optical power performance values of other 9 pieces of remote equipment under the same optical splitter connected to the remote equipment 1 to obtain an optical power performance average value.
Assuming that the calculated optical power performance average value is-20.5 dBm, and the alarm threshold range is (-24, -23.7), it can be known that-20.5 dBm is not within the alarm threshold range, which means that the full link under the central PON port a is really only one remote device 1 abnormal, where-24 in the alarm threshold range is a threshold value, -23.7 is a maximum alarm value, which is close to the threshold value, and where the maximum alarm value and the threshold value may be set by themselves according to requirements, this embodiment is merely an example and is not used to limit the present invention. If only one remote device 1 is abnormal in the whole link under the local side PON port A, judging whether the abnormal information generated by the remote device 1 is the abnormal information of the fault of the optical module of the remote PON port; if the abnormal information generated by the remote device 1 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 (namely the fault of the PON port optical module of the remote device 1); and assuming that the calculated optical power performance average value is-23.8 dBm, and the alarm threshold range is (-24, -23.7), which indicates that-23.8 dBm is within the alarm threshold range, the delimiting result is the main optical path fault.
And judging that the abnormal information generated by the single remote equipment is abnormal information of the fault of the non-remote PON port optical module, and if the optical power performance value of the single remote equipment generating the abnormal information is not in the normal threshold range, the delimiting result is a networking fault, and the delimiting result is graphically displayed on a user interface so as to be convenient for a user to check.
If the abnormal information generated by the remote device 1 is judged to be the abnormal information of the non-remote PON port optical module fault, judging whether the optical power performance value of the remote device 1 generating the abnormal information is in a normal threshold range, specifically, acquiring the optical power performance values of other 9 remote devices under the local PON port A connected to the remote device 1, counting the maximum value Vmax and the minimum value Vmin of the optical power performance values, calculating to obtain the normal threshold range according to the Vmax, the Vmin and the abnormal threshold value, assuming that the abnormal threshold value is Te, the normal threshold range is (Vmin-Te, Vmax + Te), if the abnormal threshold value is Te, counting to obtain the optical power values of Vmax is-19.5 dBm, Vmin is-23.3 dBm, and Te is 2dBm, calculating to obtain the normal threshold range is-23.3-2 dBm, 19.5+2 dBm); if the optical power performance value of the remote device 1 generating the abnormal information is-30 dBm, it can be known that the optical power performance value of the remote device 1 is-30 dBm and is not within the normal threshold range (-23.3-2dBm, -19.5+2dBm), the delimiting result is a networking fault; and if the optical power performance value of the single remote device generating the abnormal information is within the normal threshold range, the delimiting result is that the fiber to the home is abnormal. Assuming that the optical power performance value of the remote device 1 generating the abnormal 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 (-23.3-2dBm, -19.5+2dBm), the definition result is an abnormal fiber for the home, and Vmax is-19.5 dBm, Vmin is-23.3 dBm, and Te is 2dBm in this embodiment are only for illustration and are not used to limit the present invention.
And the delimitation result obtained by the information analysis module is stored in the data storage module, the result display module receives a request for viewing by a user, and the delimitation result in the data storage module is graphically displayed on a user interface for the user to view. This embodiment is merely an example and is not intended to limit the present invention.
