Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

Fig. 1 is a schematic diagram of an operation and maintenance system architecture provided in an embodiment of the present application, and as shown in fig. 1, an operation and maintenance system for an optical attenuation problem is a distributed system and is composed of an operation and maintenance platform and a comprehensive network management platform, where the operation and maintenance platform is responsible for receiving optical attenuation values uploaded by optical network units ONU in a corresponding area, and the comprehensive network management platform receives optical attenuation values uploaded by the optical network units on the operation and maintenance platform, so that an operation and maintenance person determines an optical network unit to be maintained based on the optical attenuation values of the optical network units received by the comprehensive network management platform, thereby performing order distribution.

In some embodiments, in order to improve the order dispatching efficiency, the integrated network management platform may sort the light attenuation values of the optical network units received at the current time, so that the operation and maintenance personnel dispatches orders for the optical network units with smaller light attenuation values, for example, the operation and maintenance plane of the integrated network management platform performs corresponding operations, and for example, each smaller light attenuation value is selected, so as to trigger generation and issuing of a work order of the optical network unit corresponding to the light attenuation value, thereby implementing light attenuation adjustment on each optical network unit with smaller light attenuation value.

Due to the fact that the number of the optical network units is large, operation and maintenance personnel cannot carry out dispatching rapidly and accurately, and dispatching efficiency is low; when the work order is generated, the optical network unit corresponding to the optical attenuation value can be determined only by loading a plurality of resources, so that the work order generation efficiency is low; due to the complexity of the optical attenuation problem, the optical network unit which may have the optical attenuation problem cannot be accurately evaluated based on the optical attenuation value acquired once, so that the accuracy of operation and maintenance of the optical network unit is low.

The work order generation method provided by the application aims to solve the technical problems in the prior art. The main conception is as follows: tracking of the light attenuation value is achieved based on the equipment identification in the light attenuation message, the light attenuation problem of each optical network unit is evaluated based on the light attenuation value in the light attenuation message uploaded by each optical network unit in a plurality of periods, so that the optical network unit needing to be maintained is determined through the calculated light attenuation characteristic value, the light attenuation maintenance work order of the optical network unit is generated and issued, automatic order dispatching aiming at the light attenuation problem is achieved, and the order dispatching efficiency is improved; meanwhile, the light attenuation problem is evaluated through multiple groups of light attenuation values for a long time, and the accuracy and timeliness of the order dispatching are improved.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a flowchart of a work order generation method according to an embodiment of the present application, where the method may be executed by a work order generation device, and the work order generation device may be the above-mentioned integrated network management platform 120 or other devices, and may be in the form of a computer, a server, and the like, as shown in fig. 2, the work order generation method includes the following steps:

step S201, obtaining the optical attenuation messages uploaded by each optical network unit in each period within a set time period.

The set time period may be 1 day, 3 days, 7 days, 14 days or other time periods, the set time period includes a plurality of cycles, and one cycle may be 1 hour, 2 hours, 6 hours, 12 hours, 1 day or other time periods. The optical attenuation message includes an equipment identifier of the optical network unit and an optical attenuation value of the optical network unit corresponding to the current uploading period. The device identifier of the optical network unit may be used to identify the corresponding optical network unit, and the device identifier may be composed of characters such as multi-digit numbers and letters. The optical attenuation value is the receiving optical power of the PON port of the optical network unit.

In some embodiments, the device identification may be a globally unique identification, i.e. the device identifications of different optical network units are different.

In some embodiments, the device identification may be a locally unique identification, such as one that remains unique only within the scope of the work order generating device to which it belongs, without guaranteeing global uniqueness.

Exemplarily, taking two ONUs as an example, the two ONUs are named as ONU1 and ONU2, and the two ONUs belong to or correspond to the same work order generating device, that is, are located in the same platform, the device identifiers of ONU1 and ONU2 may be 043100444781 and 043100444889, when the optical attenuation values of ONU1 and ONU2 are reported each time, the device identifiers in the generated optical attenuation messages are kept unchanged, for example, 0431004447812994, 0431004447812935, and 0431004448892763, the last four bits of the optical attenuation messages are used for describing the optical attenuation values, "0431004447812994" indicates that the optical attenuation value of ONU1 in the corresponding period is-29.94 dBm, and "0431004448892763" indicates that the optical attenuation value of ONU2 in the corresponding period is-27.63 dBm.

Specifically, the work order generating device may directly obtain the optical attenuation messages uploaded by each optical network unit in each period. Or the operation and maintenance platform arranged in each region may acquire and store the optical attenuation messages uploaded by each optical network unit in each period in the region, and then each operation and maintenance platform sends the optical attenuation messages uploaded by each optical network unit in each period to the work order generation device by using the set time period, period or other time periods as step lengths, so as to dispatch the work order according to the optical attenuation problem.

In some embodiments, each province may correspond to a work order generation device, so as to be responsible for generation and issue of work orders of each optical network unit of the province. The device identification may be globally unique only within the corresponding province. Or the device identifier may include an identifier of the work order generation device to which the work order generation device belongs, so as to obtain a globally unique device identifier.

Further, the optical attenuation messages uploaded by each optical network unit within a set time period can be preprocessed. The preprocessing may include one or more of a screening process and a legitimacy determination process. The screening treatment specifically comprises the following steps: screening the optical attenuation messages corresponding to each optical network unit based on the optical attenuation values so as to enable the number of the optical attenuation messages corresponding to each optical network unit to be a preset number; the validity judgment may include the validity judgment of a single optical attenuation message, and the validity judgment of each group of optical attenuation messages according to a set step length, such as one day, for each optical network unit. The validity judgment of the light attenuation message may include validity judgment of factors such as a light attenuation value and a date in the light attenuation message.

In some embodiments, the preprocessing may further include format conversion, for example, formats of optical attenuation messages uploaded by optical network units of different models or brands may be different, and the optical attenuation messages of the respective optical network units are converted into optical attenuation messages of a uniform format through the preprocessing.

Step S202, determining the light attenuation characteristic value of each optical network unit according to the equipment identifier and the light attenuation value in each light attenuation message received in the set time period.

The characteristic value of light attenuation may include one or more of parameters such as an average value, a variance, a maximum value, a minimum value, a mode, and the like of each light attenuation value corresponding to the optical network unit.

Specifically, the set time periods are used as step lengths, and the optical attenuation values of the optical network units are counted and tracked based on the device identifiers in the optical attenuation messages obtained in each set time period, so that the optical attenuation characteristic values of the optical network units are determined based on the optical attenuation values uploaded by the optical network units in each period in the set time periods.

Specifically, the device identifier and the light attenuation value in each light attenuation message in the set time period may be extracted, and the light attenuation characteristic value of each optical network unit may be determined based on the extracted device identifier and the corresponding light attenuation value in the preset time period.

Specifically, since the device identifier is unique within the range corresponding to the work order generating device, the optical attenuation messages uploaded by each optical network unit in each period within the set time period can be counted based on the device identifier, so as to obtain each optical attenuation message corresponding to each optical network unit; and further determining the light attenuation characteristic value of the optical network unit based on the light attenuation value in each light attenuation message corresponding to the optical network unit or the light attenuation value in each light attenuation message uploaded in a set time period.

Step S203, generating each optical attenuation maintenance work order according to the optical attenuation characteristic value of each optical network unit.

The optical attenuation maintenance work order may include an identifier of the optical network unit that needs to be maintained, and may further include information such as a historical optical attenuation value and an optical attenuation characteristic value of the optical network unit, for example, the optical attenuation value and the optical attenuation characteristic value in the set time period.

Specifically, whether the optical network unit needs to be maintained or not can be judged according to the optical attenuation characteristic value of the optical network unit, and if yes, the optical attenuation maintenance work order of the optical network unit is generated.

Further, whether the optical network unit needs to be maintained may be determined based on a comparison result between each light attenuation characteristic value and a corresponding threshold value, for example, whether an average value in the light attenuation characteristic values of the optical network unit is smaller than a second threshold, such as-27 dBm, and whether a variance in the light attenuation characteristic values of the optical network unit exceeds a preset interval may be determined, and if at least one of the values is yes, it may be determined that the optical network unit needs to be maintained.

In some embodiments, it may also be determined whether the optical network unit needs to be maintained according to the optical attenuation values in the optical attenuation messages uploaded by the optical network unit within the set time period, for example, whether an optical attenuation value smaller than the second threshold exists in the optical attenuation values in the optical attenuation messages uploaded by the optical network unit within the set time period is determined, and if the optical attenuation value exists, it is determined that the optical network unit needs to be maintained.

Further, when there are a large number of optical network units to be maintained, for example, the number of optical network units is greater than the first number of smart home engineers corresponding to the work order generating device, the optical network units may be sorted according to the optical attenuation characteristic values of the optical network units to generate the first number of optical attenuation maintenance work orders of the optical network units before ranking, so as to maintain the optical attenuation problem of the first number of optical network units before ranking.

Further, after each optical attenuation maintenance work order is generated, the responsible person of each optical attenuation maintenance work order is determined based on the address of the PON port of the optical network unit corresponding to each optical attenuation maintenance work order, and public information such as the work order number of each optical attenuation maintenance work order or each optical attenuation maintenance work order is sent to the terminal of the corresponding responsible person, such as a mobile terminal, a computer, a notebook, and the like, so that the responsible person can maintain the corresponding optical network unit.

The work order generation method provided by this embodiment is directed to a scenario of dispatching orders based on optical attenuation values of optical network units, and is implemented by controlling each optical network unit to upload an optical attenuation message including an equipment identifier and an optical attenuation value according to a set period, tracking the optical attenuation value of each optical network unit based on the equipment identifier, determining an optical attenuation characteristic value of each optical network unit based on the optical attenuation value of each optical network unit in a set time period, evaluating the optical attenuation condition of each optical network unit based on the optical attenuation characteristic value and generating an optical attenuation maintenance work order to instruct a relevant engineer to maintain the optical network unit, so that automatic dispatching orders are implemented, the dispatching efficiency is improved, the maintenance efficiency and timeliness of optical attenuation problems are improved, and the network experience of users and the satisfaction degree of broadband services are improved.

Optionally, before generating each optical attenuation maintenance work order according to the optical attenuation characteristic value of each optical network unit, the method further includes: aiming at each optical network unit, judging whether the optical network unit meets a preset condition or not according to an optical attenuation value in each optical attenuation message uploaded by the optical network unit within a set time period; correspondingly, generating each optical attenuation maintenance work order according to the optical attenuation characteristic value of each optical network unit, including: and generating each light attenuation maintenance work order according to the light attenuation characteristic value of each optical network unit meeting the preset condition.

Specifically, when the optical network unit meets a preset condition, or an optical attenuation value of the optical network unit within a set time period meets the preset condition, it is determined that the optical network unit needs to be maintained. Then, only for the optical network unit that needs to be maintained or the optical network unit that meets the preset condition, according to the device identifier of each optical network unit that meets the preset condition, each optical attenuation message that is uploaded by each optical network unit that meets the preset condition within the set time period is searched from each optical attenuation message that is received within the set time period, so that each optical attenuation maintenance work order is generated according to the optical attenuation characteristic value of each optical network unit that meets the preset condition.

By judging the preset conditions, the optical network units are screened, so that the evaluation and the subsequent work order generation are performed only on the basis of the optical attenuation messages of the optical network units with high possibility of problems, the quantity of data to be processed is reduced, and the order generation efficiency is further improved.

The second light attenuation threshold may be-26 dBm, -27dBm, -28dBm or other values, and may be determined according to parameters such as the number of optical network units corresponding to the work order generating device, the number of smart home engineers, and the like.

Specifically, the average value of the optical attenuation values in the optical attenuation messages uploaded by the optical network unit within the set time period may be an average value of non-zero optical attenuation values in the optical attenuation messages uploaded by the optical network unit within the set time period.

Through the screening of the preset conditions based on the average value, more optical network units can be filtered, so that targeted optical attenuation problem maintenance is realized, the number of optical attenuation messages to be processed is greatly reduced, the time for generating the work order is shortened, and the necessity of work order maintenance is improved.

Through a loose preset condition, the omission of the optical network units with hidden troubles of optical attenuation can be avoided, and the comprehensiveness of operation and maintenance is improved.

Fig. 3 is a flowchart of a work order generation method according to another embodiment of the present application, where this embodiment is based on the embodiment shown in fig. 2, further refines step S202 and step S203, and adds a step of preprocessing each light attenuation packet after step S201, and as shown in fig. 3, the work order generation method according to this embodiment may include the following steps:

step S301, obtaining the optical attenuation messages uploaded by each optical network unit in each period within a set time period.

The optical attenuation message includes the device identifier of the optical network unit and the optical attenuation value of the optical network unit corresponding to the current uploading period.

Step S302, based on the device identifier, searching each optical attenuation message uploaded by each optical network unit within a set time period from each optical attenuation message received within the set time period.

Step S303, for the optical attenuation packets uploaded by each optical network unit within the set time period, performing validity judgment on each optical attenuation packet uploaded by the optical network unit within the set time period to delete the optical attenuation packets that fail the validity judgment.

Specifically, whether the optical attenuation messages uploaded by the optical network unit in each set time period satisfy each legitimacy judgment condition can be judged through the preset legitimacy judgment condition.

The validity judging condition may include a validity judging condition of the light attenuation value to judge whether the light attenuation value in each light attenuation message is located in the first interval, and may also include a time validity judging condition to judge whether the reporting time of each light attenuation message is within a preset time period, and judge whether the time in the light attenuation message is consistent with the period corresponding to the light attenuation message; the validity judgment condition of the similarity can also be included, and whether the similarity between the light attenuation value in the light attenuation message of each period uploaded by the optical network unit on the current day and the light attenuation value in the light attenuation message of each period uploaded by the optical network unit on the previous day is in a second interval or not is judged aiming at each optical network unit; if the judgment result of any one of the legality judgment conditions is negative, determining that the corresponding light attenuation message does not pass the legality judgment, and deleting the light attenuation message which does not pass the legality judgment.

Through the legality judgment, the accuracy of the light attenuation value for light attenuation judgment is improved, and therefore the accuracy of the work order maintenance order is improved.

The upper limit value of the first interval may be-8 dBm, -7dBm or other values, and the lower limit value of the first interval may be-27 dBm, -28dBm or other values. The similarity may be expressed as a percentage, and the upper limit value of the second interval may be 80%, 90%, or other values, and the lower limit value of the second interval may be 10%, 20%, or other values.

Specifically, the similarity between the light attenuation values in each light attenuation message uploaded on the current day and the light attenuation values in each light attenuation message uploaded on the previous day is calculated, and the calculated similarity may be calculated as a percentage of the light attenuation values with the same numerical value and sequence of the light attenuation values in the array of the light attenuation values corresponding to the current day and the array of the light attenuation values corresponding to the previous day in the array of the light attenuation values corresponding to the current day. Or determining the similarity between the current day and the previous day according to the overlapping rate of the two curves by fitting the curve where the array of the light attenuation values corresponding to the current day and the array of the light attenuation values corresponding to the previous day are located.

Through the validity judgment, abnormal light attenuation messages, such as light attenuation messages with abnormal light attenuation value range, light attenuation messages with abnormal reporting date, and a group of light attenuation messages with extremely high or extremely low similarity between the light attenuation value and the previous group of light attenuation messages, can be deleted, so that the accuracy of the light attenuation messages for evaluation is improved.

Step S304, if the number of the optical attenuation packets that the optical network unit judges through the legality is greater than the preset number, screening each optical attenuation packet that the optical network unit judges through the legality based on the optical attenuation value to obtain the preset number of optical attenuation packets corresponding to the optical network unit.

Specifically, the screening of each optical attenuation packet of the optical network unit according to the legality judgment based on the optical attenuation value may be to delete one or more optical attenuation packets of the optical network unit with an optical attenuation value of 0 according to the legality judgment and with a larger or smaller optical attenuation value, so that the number of the optical attenuation packets corresponding to the screened optical network unit is a preset number.

For example, taking a day as a period for screening, assuming that each optical network unit needs to upload n optical attenuation messages every day, that is, the preset number is n, and the optical network unit O1 actually uploads n + n1 optical attenuation messages on a certain day, the optical attenuation values in the n + n1 optical attenuation messages can be obtained, and then n1 optical attenuation messages with the highest optical attenuation values are deleted, or n1 optical attenuation messages with the lowest optical attenuation values are deleted, or the average avg of the optical attenuation values in the n + n1 optical attenuation messages is calculated, and n1 optical attenuation messages with the largest absolute value of the difference between the optical attenuation values and the avg are deleted.

Through the screening operation, the quantity of the optical attenuation messages uploaded by each optical network unit every day is the preset quantity, so that the situation that the evaluation of the optical network units has deviation due to the deviation of the quantity of the optical attenuation values is avoided.

Specifically, if the number of the optical attenuation packets determined by the onu based on the validity determination is less than or equal to the preset number, step S304 may be omitted, and step S305 is directly performed.

Further, if the number of the optical attenuation packets judged by the optical network unit through legitimacy is smaller than the preset number, the number of the optical attenuation packets of the optical network unit can be supplemented to the preset number through an interpolation method.

Step S305, determining an optical attenuation characteristic value of the optical network unit according to each non-zero optical attenuation value in each optical attenuation message uploaded by the optical network unit within a set time period.

The characteristic value of light attenuation includes one or more of an average value, a variance, a maximum value, a minimum value and a mode of each non-zero light attenuation value in each light attenuation message uploaded by the optical network unit within a set time period.

In some embodiments, when the user does not turn on the optical network unit, in the optical attenuation message uploaded in the time period, the optical attenuation value of the optical network unit is 0. In order to reduce the influence of the light attenuation value with the value of 0 on the generation of the subsequent work order or the determination of the priority, the evaluation of the light attenuation problem is carried out aiming at the non-zero light attenuation value, and the accuracy of the work order generation and the accuracy of the operation and maintenance are further improved.

Specifically, the characteristic value of the optical attenuation of the optical network unit may be determined according to nonzero optical attenuation values in a preset number of optical attenuation messages corresponding to the optical network unit uploaded within a set time period.

Step S306, determining the order dispatching priority of each optical network unit according to the light attenuation characteristic value of each optical network unit.

The order priority is used for evaluating the possibility that each optical network unit may have the light attenuation problem, and the higher the order priority is, the higher the possibility that the optical network unit has the light attenuation problem is.

Specifically, the order priority of the onu may be determined according to one or more of an average value, a variance, a maximum value, a minimum value, and a mode of each non-zero optical attenuation value in each optical attenuation message uploaded by the onu within a set time period.

Further, a first corresponding relationship may be established in advance, and the order dispatching priority of the onu may be determined based on the first corresponding relationship and one or more of an average value, a variance, a maximum value, a minimum value, and a mode of each non-zero optical attenuation value in each optical attenuation message uploaded by the onu within a set time period. The first corresponding relation is used for describing the corresponding relation between each light attenuation characteristic value, such as an average value, a variance, a maximum value, a minimum value, a mode and the like, and the order priority.

Step S3063, if the light attenuation variance of the optical network unit is greater than or equal to the first variance, determining a dispatch priority of the optical network unit according to the light attenuation average of the optical network unit and the second relational expression.

Wherein, the first relational expression and the second relational expression are different relational expressions.

The calculation of the order dispatching priority is carried out by adopting different relational expressions in a segmented mode based on the variance, so that the setting of the order dispatching priority is more in line with the emergency degree of the light attenuation problem of the optical network unit, the accuracy of the priority setting is improved, and the accuracy and pertinence of the work order generation are further improved.

Taking the first variance of 0.5 and THR of-27 dBm as an example, it can be based on a first relation, such as P_i＝|AVG_i-THR|/VAR_iDetermining the dispatching priority of the ONU3 to be 9.47; based on a second relation, e.g. P_i＝|AVG_i-THR|×VAR_iDetermining that ONU4 has a scheduling priority of 1.72, then ONU3 has a scheduling priority much higher than ONU 4.
