Description

Technical Field

[0001] The invention belongs to the field of optical fiber communication networks, and in particular relates to a method for material cost analysis based on a hierarchical model. Background Art

[0002] Optical access network, referred to as OAN, is a communication network based on optical fiber communication technology that connects the backbone network to the end user. Compared with the traditional copper cable access method, the optical access network provides higher bandwidth, lower latency and more stable services. With the increasing demand for high-speed broadband access, optical access network has gradually become the mainstream implementation method of modern broadband access.

[0003] Although the optical fiber access network has significant technical advantages, it still faces many challenges in the implementation process of planning, design and management. For example, in the planning and design stage of the optical fiber access network, communication operators still rely mainly on manual drawing and the experience of professionals, and in the management stage of the optical fiber access network, they still rely mainly on traditional manual monitoring tools and manual analysis; such manpower-dominated methods lack the support of digital tools, which, on the one hand, makes the implementation process of the planning, design and management stages lack automation, and on the other hand, makes the information about each stage of the optical fiber access network life cycle scattered in different systems, forming independent "data islands". This makes the implementation process of the planning, design and management stages of the optical fiber access network time-consuming and complicated, and is prone to human errors, reducing efficiency. In particular, for the analysis of material costs, relying on traditional manual analysis is prone to low accuracy and low efficiency; how to accurately and efficiently implement material cost analysis without relying on the experience of professionals is an urgent problem to be solved. Therefore, in response to the above problems, this technical solution proposes a method for material cost analysis based on a hierarchical model. Summary of the invention

[0004] The present invention provides a method for material cost analysis based on a hierarchical model. This solution fully combines the full life cycle management of the optical fiber access network and systematically coordinates various factors. It can efficiently and accurately realize rapid analysis of material costs without relying on the experience of professionals, greatly improving the efficiency of material cost analysis and helping to reduce operation and maintenance costs. In summary, the problems in the background technology are solved.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The method for material cost analysis based on the hierarchical model of the present invention is managed based on the optical fiber access network full life cycle management system;

[0007] The optical fiber access network full life cycle management system receives domain knowledge from engineering practitioners and obtains digital definitions in a hierarchical model, and then classifies and integrates it into the corresponding levels of the system; the hierarchical model includes a system function layer, an entity component layer, a composite structure layer, a space attribute layer and a database; the system function layer is used to divide complex business logic into various functional modules that serve the optical fiber access network life cycle management; the entity component layer is used to define the content of each entity component involved in the full life cycle of the optical fiber access network; the composite structure layer aggregates independent entity components into a composite structure based on specific relationships, and the composite structure is aggregated by entity components; the spatial attribute layer defines various spatial attributes that characterize entities and structures; the database is used to integrate external data to provide necessary information support for the management of the full life cycle of the optical fiber access network;

[0008] Based on the data defined by the hierarchical model, the method for material cost analysis includes the following steps:

[0009] S1, taking the optical fiber access network life cycle data in the design phase as input;

[0010] S2. extracting various devices involved from the optical fiber access network life cycle data and organizing them into a device list;

[0011] S3, determine whether the device list has been traversed; if not, proceed to step S4; if yes, proceed to step S7;

[0012] S4, take out the next device in the list;

[0013] S5. According to the model information stored in the equipment, index and obtain the material cost of the equipment in the equipment database;

[0014] S6, accumulating the material cost of the equipment, and then returning to step S3;

[0015] S7, extracting an optical fiber access network cable set including each cable from the optical fiber access network life cycle data, extracting each cable included therein, and organizing each cable into a cable list;

[0016] S8, determine whether the cable list is complete; if not, proceed to step S9; if yes, proceed to step S13;

[0017] S9, taking out the next cable in the cable list;

[0018] S10, according to the model information stored in the corresponding cable, indexing in the cable database and obtaining the unit length material cost of the corresponding cable;

[0019] S11, querying the path data corresponding to the cable in the optical fiber access network life cycle data, and calculating and accumulating the length of the cable in sections;

[0020] S12, multiplying the material cost per unit length of the corresponding cable by the length of the corresponding cable to obtain the material cost of the corresponding cable and accumulating the cost, and then returning to step S8;

[0021] S13. Summarize and output the material cost of the equipment and the material cost of the corresponding cables.

[0022] Furthermore, the optical fiber access network full life cycle management system creates optical fiber access network life cycle data in the planning stage; then, the optical fiber access network life cycle data is initialized and filled in the planning stage.

[0023] Furthermore, the initialization filling is specifically: the fiber optic access network full life cycle management system determines the location of the fiber optic access network and divides the coverage area of ​​the fiber optic access network during the planning stage; and, the fiber optic access network nodes required, the locations of the nodes, and the topological relationships between the nodes are planned at this stage.

[0024] Furthermore, the fiber optic access network full life cycle management system refines the fiber optic access network life cycle data during the design phase; specifically, the system determines the equipment required to be included in each fiber optic access network node during the design phase, and determines the cables connecting the nodes and the specific wiring paths of the cables.

[0025] Furthermore, the fiber optic access network full life cycle management system updates the fiber optic access network life cycle data during the deployment phase. Specifically, it updates the data of the equipment included in the fiber optic access network nodes, the cables connecting the nodes, and the wiring paths of the cables based on the actual deployment of the fiber optic access network.
