[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] First, let’s explain the important terms:

[0051] Optical Line Terminal (OLT) is a key device located at the service provider end in passive optical network technology. Its function is to transmit the signals of multiple users through a single optical fiber to achieve signal aggregation, distribution and management. OLT is responsible for sending data to the Optical Network Unit (ONU) and managing the operation of the ONU, including bandwidth allocation, connection status monitoring, etc. OLT is usually deployed in the central computer room or in areas close to users, and communicates with the ONU at the user end through the optical distribution network.

[0052] ONU is a user-side device in passive optical network technology. It is responsible for receiving the optical signal sent by OLT and converting it into electrical signals for users to use. ONU is also responsible for converting the data signal generated by the user into an optical signal and sending it back to OLT through ODN. ONU is usually installed in the user's residence or commercial building and is the key device for users to access the optical communication network.

[0053] At present, regional power outages are mostly judged by user reports and manual inspections, which are time-delayed and cannot achieve automated and accurate fault location. Some implementations rely on monitoring equipment on the grid side to identify power outages. These devices are expensive and complex to deploy, and may not cover every household. Home gateways, OLTs, and ONUs are devices with high penetration rates in the existing communications field. Their alarm information has great potential for power outage identification, but it has not yet been fully utilized. Therefore, this application proposes a regional power outage fault identification method based on an optical communication network that is collaboratively implemented by OLT and ONU, and combined with address gridding technology to achieve fast and accurate regional power outage identification.

[0054] Compared with the existing regional power outage identification method, the present application achieves rapid identification based on real-time collected data through OLT / ONU collaboration, significantly improving the identification speed and positioning accuracy of power outage faults, and introduces a technology that combines address gridding and power outage identification algorithm to improve the accuracy of regional power outage identification. In addition, the present application utilizes existing home gateways and OLT equipment, eliminating the need for additional deployment of monitoring equipment, and effectively controlling costs.

[0055] The technical concept of the present application is that the method provided by the present application realizes regional power failure fault identification based on the optical communication network, and is applied to the optical communication network including the optical line terminal and the optical network unit, and the overall optical communication network service area is divided into multiple grids, the optical line terminal corresponds to one or more optical network units, and the same grid can include one or more optical line terminals, so as to realize the regional power failure fault identification with the grid as the unit. In the identification process, the target parameters of each corresponding optical network unit are first obtained through the optical line terminal, so as to determine the operating status of each optical network unit, and then according to the distribution of the operating status of each optical network unit in the target grid, and the distribution of the parameters specifically used to indicate the operating status of each optical network unit, it can be determined whether the power failure event occurs in each target grid, so as to complete the regional power failure fault identification, thereby, through the existing optical communication equipment in the coverage area of ​​the optical communication network, the detection of regional power failure fault is realized, and the method does not need to deploy new equipment, saving the cost of the device, and at the same time can realize the more accurate positioning of the power failure event, and improve the accuracy and efficiency of the regional power failure event identification.

[0056] See also Figure 1 , Figure 1 A flow chart of a method for identifying a regional power failure based on an optical communication network provided in one embodiment of the present application is shown in FIG. Figure 1 As shown, the method is applied to an optical communication network including an optical line terminal and an optical network unit, and the target area corresponding to the optical communication network is divided into a plurality of target grids. The method includes:

[0058] S102, determining the operating state of each optical network unit according to the target parameters of each optical network unit;

[0059] Wherein, the operating state includes a working state and a power-off state;

[0060] S103: Determine the power failure status of each target grid according to the operating status of each optical network unit in each target grid.

[0061] In a specific implementation, the method provided in this application mainly includes the following process:

[0062] Optical line terminal data collection process: The optical line terminal equipment monitors the status of the connected target optical network unit in real time, including the optical signal strength and the online / offline status of the target optical network unit. The data collection frequency is set to once a minute to ensure real-time performance. By using the power-off message reporting function of the target optical network unit and the optical line terminal, when the terminal equipment loses power unexpectedly, an alarm signal can be quickly sent to the optical line terminal. After receiving the power-off warning signal from the terminal equipment, the optical line terminal will immediately perform real-time data collection to ensure the immediacy of information transmission.

[0063] Power outage fault identification algorithm process: Analyze the data collected by the optical line terminal, determine whether a power outage has occurred, and identify the type of power outage.

[0064] Address grid management process: Convert broadband installation address information into longitude and latitude coordinates to achieve home broadband grid management. Each grid corresponds to one or more optical line terminal service areas.

[0065] Power outage area locating process: Combine the optical line terminal service area and address grid management information to quickly locate the power outage area.

[0066] The present application realizes the rapid identification of regional power outages through the collaborative work of optical line terminals and optical network units in the optical communication network, combined with the gridding capability of home broadband addresses, and improves the efficiency and accuracy of power outage fault identification and processing.

[0067] In summary, the present application uses the correspondence between the optical line terminal and the optical network unit, and the grid division of the target area, so as to achieve the recognition of power outages at the grid scale through the collaboration between the optical line terminal and the optical network unit, and convert the parameter detection of the optical network unit into the operating status.

[0068] Specifically, this embodiment realizes regional power failure fault identification based on an optical communication network, and is applied to an optical communication network including an optical line terminal and an optical network unit, and the overall optical communication network service area is divided into multiple grids, and the optical line terminal corresponds to one or more optical network units, and the same grid may include one or more optical line terminals, thereby realizing regional power failure fault identification based on grids. In the identification process, the target parameters of each corresponding optical network unit are first obtained through the optical line terminal, so as to determine the operating status of each optical network unit, and then according to the distribution of the operating status of each optical network unit in the target grid, and the distribution of parameters specifically used to indicate the operating status of each optical network unit, it can be determined whether a power failure event occurs in each target grid, thereby completing the regional power failure fault identification, thereby, through the existing optical communication equipment in the coverage area of ​​the optical communication network, the detection of regional power failure faults is realized, and the method does not need to deploy new equipment, saving the cost of the device, and at the same time can realize more accurate positioning of power failure events, thereby improving the accuracy and efficiency of regional power failure event identification.

[0069] As an optional implementation manner, the specific manner of dividing the target area into a plurality of target grids includes:

[0070] Determining a grid size and coordinates of reference points of the target area;

[0071] The reference point coordinates of the target area include reference longitude and reference latitude, which are used to indicate the boundaries of data detection and data processing of the target area;

[0072] The target area is divided into a plurality of target grids according to the grid size and the reference point coordinates.

[0073] See also Figure 2 , Figure 2 A schematic diagram of an application scenario of a method for identifying a regional power failure based on an optical communication network provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, 10 indicates an optical line terminal, 11 indicates an optical network unit, and the boxes in the figure are grids obtained by division. Obviously, one grid may include service areas of multiple optical line terminals, or may only include one, and one optical line terminal may also correspond to one or more optical network units.

[0074] It should be noted that when the optical line terminal and the optical network unit belong to different grids, the data can be summarized into the grid where the optical line terminal is located, or can be retained on the original grid of the optical network unit, depending on the specific application scenario.

[0075] This embodiment determines the grid size and the coordinates of the reference points of the target area, and then determines the boundaries of data detection and data processing in the target area, that is, the service boundaries of the optical communication network, and determines the grid division method, so as to divide the target area into grids, realize grid management, and ensure that each grid includes at least one optical line terminal, thereby ensuring the effectiveness of the fault identification method based on the optical communication network provided by the present application at the grid scale, realizing more accurate positioning of power outage events, and improving the accuracy and efficiency of identifying regional power outage events.

[0076] As an optional implementation manner, dividing the target area into a plurality of target grids according to the grid size and the reference point coordinates includes:

[0077] Determining the horizontal number and the vertical number of each target grid according to the size of the target area;

[0078] According to the first formula, the lower left corner coordinates corresponding to each target grid are calculated, and the target area is divided into a plurality of target grids;

[0079] Wherein, the first formula includes:

[0080]

[0081]

[0082] Wherein, each of the target grids comprises a square grid, d is the grid side length of the target grid, is the mean radius of the Earth, and are the minimum latitude and longitude of each target grid, as the lower left corner coordinates of each target grid, i and j are the horizontal and vertical numbers of each target grid, respectively. and are respectively the reference latitude and reference longitude of the target area.

[0083] This implementation method determines the coordinate number of each target grid by the size of the target area and the size of each target grid, and then calculates the longitude and latitude coordinates of the lower left corner of each target grid, thereby realizing the division of the target grids and realizing grid management, thereby ensuring the effectiveness of the fault identification method based on the optical communication network provided by the present application at the grid scale, realizing more accurate positioning of power outage events, and improving the accuracy and efficiency of identifying regional power outage events.

[0084] As an optional implementation, the method further includes:

[0085] Determine the target grid belonging status of each optical line terminal and each optical network unit according to the installation position of each optical line terminal and each optical network unit;

[0086] And, determining the power failure status of each of the target grids according to the operating status of each of the optical network units in each of the target grids includes:

[0087] The power failure status of each target grid is determined according to the operation status of each optical network unit and the target grid belonging status of each optical network unit.

[0088] After completing the grid management system establishment process of the target area, this embodiment determines the installation position of each optical line terminal and each optical network unit, and determines the corresponding grid affiliation according to the specific coordinates of longitude and latitude. Then, the power outage status of the target grid can be calculated through the target grid affiliation of each optical network unit, as well as the operating status and corresponding parameters of the corresponding optical network unit, thereby realizing the detection of regional power outage faults, and realizing more accurate positioning at the grid scale during the power outage event detection process, thereby improving the accuracy and efficiency of identifying regional power outage events.

[0089] As an optional implementation manner, acquiring, through the optical line terminal, a target parameter of each optical network unit corresponding to the optical line terminal includes:

[0090] Detecting the optical signal and the online state of the target optical network unit by the optical line terminal according to a preset period;

[0091] The optical signal mutation parameter is obtained through the optical signal calculation, and the offline frequency is obtained through the online state calculation.

[0092] This embodiment, based on the correspondence between optical line terminals and optical network units, detects the optical signals and online status of the corresponding optical network units through the optical line terminals, and then calculates the optical signal mutation parameters and offline frequencies, thereby providing a data basis for subsequent offline status detection of optical network units, and indicates power outages within the grid through the offline status of optical network units that occur synchronously in batches, thereby realizing the detection of regional power outages, achieving more accurate positioning at the grid scale during the power outage event detection process, and improving the accuracy and efficiency of identifying regional power outage events.

[0093] As an optional implementation, the method further includes:

[0094] Monitoring the power supply voltage by a voltage comparator in the target optical network unit, generating the power failure warning signal if the power supply voltage is lower than a voltage threshold, and transmitting the power failure warning signal to an optical line terminal corresponding to the target optical network unit;

[0095] Specifically, the optical line terminal device monitors the status of the connected target optical network unit in real time, including the optical signal strength and the online / offline status of the target optical network unit. The data collection frequency can be set to once a minute to ensure real-time performance. By implementing a power-off message reporting mechanism between the target optical network unit and the optical line terminal, when a terminal device, such as the target optical network unit, loses power unexpectedly, an alarm signal can be quickly sent to the optical line terminal. This mechanism monitors the power supply voltage of the target optical network unit through a voltage comparator. Once the voltage drops to a set threshold, the power stored in the supercapacitor is used to perform critical final operations, including sending a power-off warning and safely saving data. The optical line terminal can continuously monitor data, or it can immediately perform real-time data collection after receiving a power-off warning signal from the target optical network unit, ensuring the immediacy of information transmission and reducing the amount of data processing.

[0096] In a specific application scenario, the parameters of the optical line terminal itself can also be detected, and the power failure event can be determined by combining the operating status of the optical line terminal itself with the parameters of each target optical network unit.

[0097] Within the sliding monitoring window, if the optical line terminal detects the power off warning signal of the target optical network unit, or the optical signal mutation parameter of the target optical network unit exceeds a first threshold, or the offline frequency of the target optical network unit exceeds a second threshold, it is determined that the target optical network unit is in a power off state.

[0098] For example, the sliding monitoring window can be based on a half-hour time scale. Using a sliding window algorithm, with half an hour as a window, data cleaning modeling is performed on the data continuously collected in real time by the optical line terminal, and the following calculation formula is used to determine the power outage event:

[0099] Optical signal mutation parameters:

[0100]

[0101] in, represents the change in the intensity of the optical signal, that is, the optical signal mutation parameter, and Respectively represent the light signal intensity at two consecutive time points.

[0102] ONU offline frequency calculation:

[0103]

[0104] in, Indicates the ONU offline frequency. Indicates the number of offline times. Indicates the total number of monitoring times.

[0105] The threshold is set according to the actual application scenario. When the terminal device has a power-off warning signal within the sliding window, or the change in optical signal strength drops by more than 3dBm, or the ONU offline frequency exceeds 30%, it is judged that a power-off event has occurred in the corresponding optical line terminal.

[0106] This embodiment determines whether a power outage occurs in the target optical network unit through the power outage warning signal of the target optical network unit, as well as the optical signal mutation parameters and offline frequency of the target optical network unit. Its judgment index has good physical interpretability, which improves the effectiveness and efficiency of detecting power outage events in the target optical network unit.

[0107] As an optional implementation manner, determining the power outage status of the target grid area according to the operating status of each of the optical network units includes:

[0108] Counting the proportion of the target optical network units in the target grid area that are in a power-off state within a preset time period, and calculating a confidence score for the regional power-off range;

[0109] Counting the power-off time distribution of the target optical network units in the target grid area that are in a power-off state within the preset time period, and calculating the regional power-off time similarity confidence score;

[0110] The power outage situation of the target grid area is determined according to the regional power outage range confidence score and the regional power outage time similarity confidence score.

[0111] For example, the preset time period may be set to half an hour in an actual application scenario, and specific implementation methods may include:

[0112] For half an hour, the number of households without power in the same target grid is accumulated to obtain the number of households without power in the target grid during this period (the number of optical network units with power outage events). , combined with the total number of home gateway households in the target grid (the total number of optical network units in the target grid) , and the confidence score of regional power outage range is obtained:

[0113]

[0114] For half an hour, the power outage time patterns of different OLT / ONUs in the same grid are analyzed, and the time standard deviation of the power outage time of all devices in the target grid during this period is calculated to obtain the regional power outage time similarity confidence score. :

[0115]

[0116] Among them, the power-off timestamp is: , used to indicate the time node when a power outage occurs within a half-hour monitoring period.

[0117] The final regional power outage confidence in the target grid is divided into The higher the score, the higher the confidence level. The limit value can be set in advance. ,like , it is considered that there is a regional power outage in the target grid.

[0118] In addition, under such quantitative indicators, the degree of power outage events in each target grid can be further detected, which can further provide a basis for the response of power outage time. For example, when the confidence score of regional power outage time similarity is greater than a certain value, the higher the confidence score of the regional power outage range, the more serious the power outage event is, and the higher the scheduling processing priority is.

[0119] This embodiment determines the distribution of power outages in each target optical network unit in the target grid area within a preset time period, and then determines a quantized regional power outage range confidence score and a regional power outage time similarity confidence score, and then determines the power outage situation in the target grid area based on these two indicators, thereby achieving the effect of detecting regional power outages through an optical communication network, and can achieve more accurate positioning of power outage events, thereby improving the accuracy and efficiency of identifying regional power outage events.

Figure 3 As shown, when the various embodiments are combined and applied, a specific process can be as shown in the figure, and the specific implementation method of each step can refer to the corresponding embodiment. However, it should be noted that for the grid division step, the processing can be completed before the optical line terminal device monitors the target parameters of the connected target optical network unit in real time, and a corresponding grid management system is established. If the amount of data is large, it can also be implemented simultaneously with the optical line terminal device monitoring the target parameters of the connected target optical network unit in real time. When determining the operating status of each optical network unit according to the target parameters, it is integrated with the corresponding grid information for processing.
