Description

Technical Field

[0001] The present invention belongs to the technical field of line key point identification, and in particular relates to a transmission line key point identification method and a hidden danger rectification method. Background Art

[0002] With the development of communication services and the development of the four major "CHBN" markets in the 5G era, line resources are becoming increasingly large and complex. The number of township lines (pipelines, poles, wall-mounted, etc.) alone is as high as 7.4 million+, and is growing rapidly at a rate of about 300,000+ per year, resulting in a continuous increase in the maintenance cost of transmission lines. Line failure accidents caused by frequent natural disasters occur from time to time. Lines across roads, across rivers, along rivers / hanging bridges, etc. are more prone to safety hazards, affecting the stable operation of the optical cable line network, and having a serious impact on business development and customer perception.

[0003] In the existing technical solutions, the determination of key points of routes across roads, across rivers / bridges, along rivers, and at exits currently relies mainly on manual on-site surveys, or logging into the transmission pipeline system, manually dragging the GIS map to the vicinity of rivers and roads, and determining whether there are key transmission line resources in the surrounding areas. However, the amount of transmission line resource data is huge, and manual verification of each section is time-consuming and labor-intensive. In addition, some towns are remote and the cost of on-site stations is high. The efficiency of manual analysis can no longer meet the requirements for the inspection of key points of transmission lines, and there are situations where key hidden dangers cannot be effectively verified. In addition, maintenance personnel cannot know in advance the number of home broadband users carried by the line, such as whether it exceeds 2,000 or 500 households, resulting in the failure to regularly strengthen inspections of key points of transmission lines with heavy business loads, and the inability to promptly discover safety hazards and effectively avoid multi-user group failures.

[0004] Based on this, how to quickly identify the key point resources of the transmission line, automatically analyze the key points of crossing the road, crossing the river / hanging the bridge, along the river, exit routing, and business overload types, and output a specific line list, as well as improve the efficiency of optical cable line maintenance, has become an urgent problem to be solved. Summary of the invention

[0009] In order to better implement the present invention, further, identifying the outbound routing key point includes the following steps: Step A1: Obtain the office direction of the site: Based on the office direction relationship, analyze the office directions of all reachable Z-end sites starting from the end site; Step A2: Obtain the transmission lines associated with the office direction: Starting from the end site, all office directions are traversed in a loop, and the first 10 transmission lines of each office direction starting from the end site are connected in series by using the two-dimensional logical relationship of office direction → optical cable segment core → transmission line; if an optical device / site is found in advance and there are still less than 10 transmission lines, the search is terminated, and the current lines are connected in series to obtain the transmission lines associated with the office direction; Step A3: Use the serially connected transmission line as the outgoing routing key point.

[0010] In order to better implement the present invention, further, the key points of the transmission line are visualized in combination with the form and the GIS map: the key points of the transmission line are queried and displayed, and the geographical locations of the key points in the surrounding areas are displayed in combination with the GIS map.

[0011] The present invention is mainly achieved through the following technical solutions: A method for rectifying hidden dangers at key points of a transmission line, which obtains key point information based on the above-mentioned method for identifying key points of a transmission line; and comprises the following steps: Step S1: Acquire key point information, identify key points and mark service-heavy transmission lines; Step S2: Create files for key points, and give priority to key points of business overload; Step S3: Formulate a plan. If on-site rectification is required, proceed to step S4; otherwise, proceed to step S5; Step S4: On-site remediation. If the plan is wrong, go to step S3, otherwise go to step S5; Step S5: Remediation review. If the review is passed, it will be archived. If the plan formulation review fails, go to step S3. If the filing information is incorrect, go to step S2.

[0016] The beneficial effects of the present invention are as follows: (1) The present invention analyzes the key points of transmission lines based on GIS map + resource data + Oracle Spatial spatial component analysis technology, marks overloaded lines, and outputs a list of key points of transmission lines. The present invention further realizes the identification, filing and rectification of key points based on AI intelligent assistance, establishes a closed-loop control process, and effectively implements the on-site filing of key points and the rectification of hidden dangers. Specifically, the present invention makes the entire key point filing process and hidden danger rectification process IT online, automated, and intelligent, covering 100% of the transmission lines in the province, so that the efficiency of key point investigation is improved by at least 35%. Secondly, daily relocation and cutover will trigger changes in key points of transmission lines, and there is a situation where system resources are not changed in time, resulting in inconsistency between system and on-site resources. In view of this scenario, the present invention makes full use of the opportunity for maintenance personnel to go to the site to build files, and with the help of maintenance personnel, triggers resource errata, effectively improving the resource accuracy of key points of transmission lines.

[0017] (2) Improved the efficiency of checking key points of transmission lines: Faced with the complex situation where the number of transmission lines is as high as 7.4 million and is growing rapidly at a rate of more than 300,000 per year, the present invention makes the entire key point filing process and hidden danger remediation process online and automated, and provides Baidu navigation tools to output navigation routes to key points of transmission lines, assisting maintenance personnel to build files on site, thereby improving the efficiency of key point inspection by at least 35%.

[0018] (3) Improved the verification accuracy of key points of transmission lines: The present invention only requires GIS map + resource data information, combined with Oracle Spatial spatial component functions, to automatically complete the verification of transmission key points. Compared with manual verification, the verification dimension is more comprehensive, covering four types of key points: crossing roads, crossing rivers / hanging bridges, along rivers, and outbound routes. It can also identify key points of heavy-loaded services, with more detailed verification accuracy, ensuring 100% mining of key points of transmission lines.

[0019] (4) Output results can be checked anytime and anywhere: The handheld APP terminal can be used to query and collect information on key transmission points in various cities, districts, counties, and towns anytime and anywhere; and it has GIS map visualization capabilities, which makes it easy for transmission operation and maintenance personnel to intuitively grasp the geographical location of key points.

[0020] (5) Improved resource accuracy at key points of the transmission line: During the on-site file creation process, if the maintenance personnel find that the on-site information of key points is inconsistent with the system, they can trigger resource errata, which effectively improves the resource accuracy of key points of the transmission line.

[0021] (6) Reduced the number of group failures and improved the security of the transmission network: The present invention automatically outputs a list of key transmission points, and through on-site filing and hidden danger rectification by maintenance personnel, group failure hazards can be discovered and handled in a timely manner, thereby reducing the number of group failures.

DETAILED DESCRIPTION

[0023] Embodiment 1: A method for identifying key points of transmission lines, an automatic identification and archiving tool for key points of transmission lines based on "resources + GIS maps" In order to solve the pain points of the above transmission line maintenance, a "4+1" transmission line key point hierarchical archiving work mode is adopted - regular archiving of four types of key points, namely, cross-road, cross-river / bridge, along the river, and outbound routes, and priority is given to archiving the key points of business overload. For example: it can be applied to a comprehensive risk assessment of the transmission lines in the province, and the hourly level can automatically identify which areas in the province have key points of transmission lines, greatly saving the time for checking key points of transmission lines, effectively improving the timeliness of hidden danger discovery, improving the safety and stability of transmission lines in our province, reducing business interruptions, and thus improving customer perception. Secondly, with the help of maintenance personnel, resource errata can be triggered, effectively improving the resource accuracy of key points of transmission lines. Provincial and municipal operation and maintenance personnel can conduct on-site archiving of key points automatically identified by the system at any time. Once hidden dangers are found, corresponding preventive or repair measures can be taken immediately to ensure the safety of transmission lines and effectively support network operation and maintenance work.

[0024] The specific steps of the present invention are as follows: The present invention is mainly based on GIS map + resource data + Oracle Spatial spatial component analysis technology.

[0025] When the resource entry personnel enter two AZ endpoint resources (manholes, electric poles, etc.) in the GIS map of the transmission pipeline system, the system automatically generates a line resource (pipeline, pole line, wall hanging, etc.), takes the longitude and latitude of the two point resources as input parameters, and uses Oracle Spatial spatial component functions to establish the spatial coordinates of the key points of the transmission line (pipeline, pole line, wall hanging, etc.) to obtain the resource data.

[0026] A new data model is created to store spatial data of rivers, roads, bridges, and administrative areas in electronic maps. The spatial coordinates of line resources and surface resources are used as input parameters, and Oracle Spatial spatial component functions are used to automatically analyze line resources across roads, across rivers, and along rivers / bridges from points to lines and from lines to surfaces, thereby automatically identifying hidden dangers at key points on transmission lines.

[0027] Preferably, the identification rules of relevant key points are as follows: (1) Across the road: Figure 1 As shown in the figure, there is an intersection area (intersection) between the line resources and the road surface, which is the key point of cross-road hidden danger.

[0028] (2) Cross-river / hanging bridge: Figure 2 As shown, the line resource and the river surface intersect, which is the key point across the river; the line resource falls within the boundary of the bridge or is 5 meters away from the boundary of the bridge deck, which is a hanging bridge.

[0029] (3) Along the river: Figure 3 As shown, the center point of the line resource is less than or equal to 20 meters away from the river boundary and cannot intersect with the river surface boundary, that is, it is along the river.

[0030] (4) Outgoing routing: Figure 4 As shown, analyze the outbound transmission route from [sites above access aggregation] to [sites above access aggregation]: a. Site direction: Starting from site A, analyze all Z-end sites (above access aggregation) reachable from site A based on the direction relationship, such as site A->site B, site A->site C.

[0031] b. Transmission lines associated with office directions: Starting from site A, all office directions are traversed in a loop, and the first 10 transmission lines of each office direction from site A are connected in series by using the two-dimensional logical relationship of "office direction->optical cable segment core->transmission line"; if optical equipment / site is found in advance and there are still less than 10 transmission lines, the search is terminated and the current lines can be connected in series.

[0032] c. The transmission line after serial connection serves as the key point of the transmission outgoing line.

[0033] (5) Identification of service-heavy lines: After identifying the four key points of cross-road, cross-river, riverside / bridge, and outbound routing, the number of home broadband users carried by each key point of the transmission line is calculated based on the relationship between the internal and external line resources of the transmission line and the PON port: a. Relationship between the transmission line (pipeline, pole, etc.) and the fiber core of the optical cable segment: obtain the fiber core of the optical cable segment carried by the transmission line.

[0034] b. Relationship between the fiber core of the optical cable segment and the local direction: According to the fiber core of the optical cable segment, analyze the end-to-end local direction information, such as: A-end terminal -> Z-end terminal information.

[0035] c. Relationship between the office direction and the optical path: According to the analysis of the AZ terminal of the office direction, the optical path information associated with the terminal is obtained, and the associated PON port information is analyzed through the A-end port field of the optical path.

[0036] d. Number of home broadband users associated with a PON port: According to the PON port view provided by the business resource system, obtain the number of home broadband users associated with each PON port.

[0037] e. After the above vertical relationship is extracted, a two-dimensional logical relationship of "transmission line->optical cable segment core->office direction->optical path->number of home broadband users associated with PON port" is formed. The system automatically sums and accumulates the [number of home broadband users] fields of multiple PON ports associated with the transmission line to realize automatic identification of key points of business overload.

[0038] Embodiment 2: A method for rectifying hidden dangers at key points of a transmission line, such as Figure 5 As shown, the following steps are included: (1) Automatic identification of key points of transmission lines The present invention is based on transmission line resource data, rivers, roads, bridges, and administrative district data in electronic maps, and utilizes Oracle Spatial spatial component functions of Oracle database to automatically analyze key points of transmission lines across roads, across rivers, along rivers / hanging bridges, and outbound routes, thereby realizing automatic identification of four types of transmission line key points. On this basis, business-heavy transmission lines are marked, providing basic data for hierarchical archiving of transmission line key points.

[0039] Preferably, the transmission line key point identification algorithm is: ① Cross-road: There is an intersection area (intersection) between line resources and road surface, which is the key point of cross-road hidden danger.

[0040] ② River crossing / hanging bridge: When the line resource and the river surface intersect, it is a river crossing key point; when the line resource falls within the boundary of the bridge or is 5 meters away from the boundary of the bridge surface, it is a hanging bridge.

[0041] ③ Along the river: The center point of the line resource is less than or equal to 20 meters away from the river boundary and cannot intersect with the river surface boundary, that is, along the river.

[0042] ④ Outgoing route: Analyze the outgoing transmission route from [sites above access aggregation] to [sites above access aggregation], and connect the first 10 lines from the A-end site in series; if the optical device / site is found in advance, stop the connection.

[0043] ⑤ Business overload line identification: After identifying the four key points of cross-road, cross-river, along-river / bridge, and outbound routing, the number of home broadband users carried by each key point of the transmission line is calculated based on the correlation between the internal and external line resources of the transmission line and the PON port.

[0044] (2) Visual presentation of key points of transmission lines combined with forms and GIS maps like Figure 6 As shown, the present invention supports querying and displaying key points of transmission lines for set query conditions (such as the number of users carried by the laying section, etc.), and maintenance personnel can give priority to querying the list of key points with heavy business loads; and combine with GIS maps to grasp the geographical locations of key points in the surrounding areas; use Baidu navigation to go to the vicinity of key points of the transmission line, and provide transmission operation and maintenance personnel with convenient key point navigation tools to improve site access efficiency.

[0045] (3) File the key points of the transmission line like Figure 7 As shown, in the present invention, the maintenance personnel go to the key points of the transmission line with a handheld APP terminal, take photos of the site, record the on-site resource information (whether the pole is tilted, whether a power protection cover has been added, etc.), and form an archive of the key points of the transmission line.

[0046] (4) Rectification and review of hidden dangers at key points of transmission lines like Figure 8 As shown, in the present invention, when there are hidden dangers at the key points of the transmission line (such as cable sagging), a remediation plan needs to be formulated for on-site remediation. After the remediation is completed, the maintenance personnel need to take photos after the remediation. Resource management personnel can review the key point file information and on-site remediation information through the APP. If it fails, it can be rolled back; if it passes, the key point is automatically completed.

[0047] (5) Transmission line key point resource errata like Fig. 9 As shown, in the present invention, when the on-site information of the key points of the transmission line is inconsistent with the system, the maintenance personnel can initiate an errata work order to notify the resource errata personnel to log in to the transmission pipeline system web->correction pool to correct the system resources. With the help of the maintenance personnel, the resource errata is triggered, which effectively improves the resource accuracy of the key points of the transmission line.

[0048] (6) Visualized transmission line key point identification rule configuration like Fig.10 As shown, the present invention can set the transmission line key point identification rule parameters online, such as the distance along the river, the distance of the hanging bridge, and the site type at the AZ end of the outlet route. The system automatically identifies the key points of the transmission line according to the configured parameters, decouples the key point identification rules, and achieves the self-intelligent network L3 level.

[0049] (7) Documentation of key points of transmission lines and visualization of progress of hidden danger remediation like Fig.11 As shown, the present invention uses APP to count and query the progress of archiving key points of transmission lines, the progress of hidden danger rectification, etc. in various cities, counties, and towns at any time and anywhere, which is convenient for provincial and municipal resource management personnel to track the progress in real time.

[0050] Embodiment 3: A method for rectifying hidden dangers at key points of transmission lines based on AI intelligent assistance, which realizes the identification, archiving and rectification of key points of transmission lines based on AI intelligent assistance. AI intelligent assistance intelligently identifies hidden dangers at key points of transmission lines, and analyzes and searches in the corresponding key point archive based on the identified key point information of transmission lines, matches at least one key point rectification plan, and then assists and guides on-site personnel to rectify the hidden dangers at the key points based on the plan.

[0051] Preferably, a health assessment function is also included, which estimates the key point resource life cycle, utilization rate, key point equipment service life, and overall health score of the key point equipment based on the historical data information of the key points.

[0052] Preferably, a key point statistical analysis table is also included, including: key point type, key point remediation reason, key point remediation plan, remediation time and completion time.

[0053] Preferably, if Figure 5 As shown, the present invention specifically comprises the following steps: 1. Obtaining the key point information by identifying the key points; 2. Based on the key point information, corresponding hidden danger remediation information associated with the key point or key points of the same type is determined; 3. According to the key point information and hidden danger remediation information, analyze and search in the key point archives to match the corresponding on-site filing and remediation plan; 4. According to the on-site remediation plan, guide service personnel to eliminate hidden dangers at the key points.

[0054] Specifically, the AI ​​intelligent assistance demonstrates the corresponding standard operating procedures using text and / or audio according to the remediation plan, and guides on-site personnel to eliminate hidden dangers according to the text and / or audio.

[0055] AI intelligent assistance can also use the health assessment function to estimate the life cycle, utilization rate, service life of key point equipment, and overall health score of key point resources, and conduct inspections on key point resources to prevent hidden dangers in advance.

[0056] The method provided by the present invention effectively combines key point hidden danger information and hidden danger solutions in an intelligent way, and provides service personnel with an efficient and accurate key point hidden danger solution guidance plan. This can not only improve the efficiency and quality of key point hidden danger treatment, but also reduce additional losses caused by misdiagnosis or improper operation.
