Description

Technical Field

[0001] This invention belongs to the field of cable monitoring technology, and specifically relates to a method for monitoring the entire life cycle of power plant cables based on full-process identification and mobile terminal scanning. Background Technology

[0002] As a key carrier for power transmission and distribution, the safe and stable operation of power plant cables directly affects the safe production and economic benefits of the power plant. With the continuous expansion of power plant scale and the continuous increase in unit capacity, the number of cables is growing exponentially, and traditional cable management models can no longer meet the needs of the refined management of modern power plants.

[0003] Currently, power plant cable management primarily relies on a combination of manual records and paper archives. During cable laying, construction personnel register cable routes, specifications, and other information using paper drawings and manual records. During operation and maintenance, inspection personnel record cable status using paper inspection forms, and fault handling depends on experience and verbal instructions. During decommissioning, cable disposal information often lacks systematic recording. This traditional management model suffers from numerous technical shortcomings: First, the main problem is that cable information management is fragmented and isolated, with data from each stage of design, production, construction, operation and maintenance, and decommissioning stored in isolation. The lack of unified data standards and correlation mechanisms makes it difficult to trace cable information throughout its entire life cycle, and it is difficult to quickly locate historical data and related information once a fault occurs.

[0004] Secondly, the secondary problem is that on-site operation efficiency is low. Inspection, fault handling and other processes rely on paper records. Data entry is cumbersome and prone to errors. Information transmission is delayed, making it impossible to achieve real-time data sharing and collaborative operations, which seriously affects the operation and maintenance response speed and decision-making efficiency.

[0005] Cable condition monitoring methods are limited and lack intelligent early warning mechanisms. They mainly rely on regular inspections and manual experience to make it difficult to detect potential hazards such as insulation aging and abnormal temperatures in a timely manner. This results in insufficient fault prevention capabilities and significant safety risks.

[0006] Cable asset management is rudimentary, lacking a scientific evaluation system based on full life-cycle data. Decommissioning and disposal decisions lack data support, resulting in low asset utilization and difficulty in effectively implementing environmental protection requirements.

[0007] Therefore, there is an urgent need to develop a monitoring method that can realize digital and intelligent management of the entire life cycle of cables. Summary of the Invention

[0008] The technical problem to be solved by this invention is to provide a method for monitoring the entire life cycle of power plant cables based on full-process identification and mobile terminal scanning. By deeply integrating full-process identification and mobile terminal scanning technologies, a unified data standard and business process are constructed to achieve full traceability and controllability of cables from design to decommissioning, thereby improving the level of precision and intelligence in power plant cable management.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A method for monitoring the entire lifecycle of power plant cables based on end-to-end identification and mobile terminal scanning, characterized by the following steps: A layered architecture is constructed, consisting of a data acquisition and identification module, a data transmission module, a data processing and management platform module, and a business application module, to achieve digital management and control of the entire lifecycle of cables from design to decommissioning; The data acquisition and identification module is used to achieve unique identification of cables and on-site data acquisition, including unified coding and identification carrier deployment; The data acquisition and identification module and the data processing and management platform module are realized through the data transmission module. The transmission method combines wireless and wired transmission to adapt to the complex field environment of power plants. The management platform is built using the Spring Boot lightweight framework in the data processing and management platform module. It adopts a front-end and back-end separation design. The back-end integrates SpringMVC and MyBatis-Plus to realize interface development and data persistence, while the front-end uses Vue.js + ECharts to realize visualization. By leveraging the business application modules to develop targeted functional modules for different positions in the power plant, we can achieve business digitization at all stages of the entire lifecycle. The design focuses on the core business processes for the full lifecycle management of power plant cables, emphasizing the deep integration of full-process identification binding and mobile terminal QR code interaction. These core business processes include cable coding and file creation, QR code construction and quality acceptance, QR code inspection and fault handling, and decommissioning assessment and environmental disposal.

[0010] Preferably, the step of assigning a unified code using the data acquisition and identification module includes: The Ecode128 general code in GB / T31866—2023 "Internet of Things Identification System Item Coding Ecode" is adopted as the unique code for each cable product. The total length is 33 decimal digits, which includes the manufacturer code, model specification code, production date code, and laying area code. Encryption algorithms ensure code security and prevent counterfeiting; For different types of cables in power plants, a classification code is added on the basis of a unified code to achieve refined management.

[0011] Preferably, the step of deploying the identification carrier in the data acquisition and identification module includes: Select the appropriate carrier based on the cable laying environment and size characteristics of the power plant; For cables with an outer diameter of ≥10mm, a combination of QR code and numerical characters is used for identification. The cable information is printed directly on the cable surface using a portable cable marking machine. The marking is printed once at regular intervals, and the printing is done in multiple lines. For small-sized cables, use single-line printing; All markings are permanently attached to the cable body to ensure identifiability throughout its entire lifecycle.

[0012] Preferably, the step of collecting on-site data using the data acquisition and identification module includes: The cable inspection data, status monitoring data, and fault data are collected through the scanning function of mobile terminals. To achieve paperless and standardized recording of on-site data.

[0013] Preferably, the step of data interaction using the data transmission module includes: The QR code scanning data collected by the mobile terminal is uploaded to the management platform via 4G / 5G / Wi-Fi / data cable; In accordance with the requirements of GB / T22239 network security level protection, the security and reliability of data transmission are ensured through encrypted transmission and authorization verification.

[0014] Preferably, the core functions of the data processing and management platform module include: Data storage and management: Establish a full lifecycle database for cables, covering design data, production data, construction data, operation and maintenance data, and decommissioning data, to achieve centralized storage, multi-dimensional retrieval, and dynamic updates of data; Multi-source data fusion: It integrates manual data collected by scanning codes with online monitoring data collected by sensors, and eliminates data redundancy and errors through data cleaning and standardization. Intelligent analysis and early warning: Based on cable operation data, a condition assessment model and a fault early warning model are constructed. Machine learning algorithms are used to analyze the characteristics of potential hazards such as insulation aging and abnormal temperature. When the monitored indicators exceed the threshold, a graded early warning is automatically issued, and the location, type and handling suggestions of the hazard are pushed. At the same time, combined with the cable health score, the priority of condition-based maintenance is sorted.

[0015] Preferably, the core functional modules of the business application module include: Design and Production Management Module: Enables the application, issuance, and assignment of cable codes, binds design parameters and production testing data, and forms digital cable archives; Construction management module: Construction personnel can scan codes to complete cable delivery acceptance, laying records, and joint fabrication information uploads. Management personnel can monitor construction progress and quality in real time, and acceptance data is automatically synchronized to the cable digital archive. Mobile Maintenance Module: Maintenance personnel can quickly query basic cable information and historical records by scanning a code, and complete the on-site uploading of inspection data and fault data, realizing closed-loop management of "defect reporting → maintenance push → repair execution → quality acceptance → data archiving". In other words, it enables maintenance personnel to quickly query basic cable information and historical records by scanning a code, and complete the on-site uploading of inspection data and fault data, achieving full-process digital management of defect information collection, maintenance task assignment, repair operation execution, acceptance result confirmation, and maintenance data archiving.

[0016] Status monitoring and early warning module: Displays cable operating status data and health score in real time, pushes graded early warning information, and supports early warning cause analysis and handling solution query; Decommissioning Management Module: Based on the cable's entire life cycle data, assess the remaining lifespan and environmental disposal requirements to enable the classification management and disposal plan formulation for decommissioned cables.

[0017] Preferably, the cable coding and file creation process includes the following steps: Power plant engineers compile cable lists, and after confirming the information on the cable lists, they apply to the platform for Ecode unified encoding. The platform automatically generates a unique code and assigns it to the corresponding cable, and binds it with the cable's detailed information, including cable name, cable model, start and end points, and cable length. The platform automatically creates digital files for cables based on the codes, integrates production and application data, and forms the basic data for full life cycle management.

[0018] Preferably, the QR code scanning construction and quality acceptance process includes the following steps: After the cables arrive, the construction personnel use a mobile terminal to input the cable details into a portable cable marking machine, verify the cable code and parameters, and mark the corresponding cables throughout the process after confirming that they are correct. During the laying process, construction workers scan codes to record laying time, path, and bending radius data. After the joint is made, they upload process parameters and test data. After construction is completed, management personnel scan the code to verify the construction data, complete the quality acceptance through on-site testing, and synchronize the acceptance data to the digital archive after the acceptance is qualified, and the cable is officially put into operation.

[0019] Preferably, the barcode scanning inspection and fault handling process includes the following steps: The platform automatically generates inspection plans based on cable health and laying area and pushes them to the mobile terminals of maintenance personnel. After the maintenance personnel arrive at the site, they scan the code to complete the inspection check-in, collect cable appearance, temperature, and partial discharge data and upload them on site. If any hidden dangers are found, they will directly report the fault and mark the type and location of the hidden danger. After receiving the fault information, the platform automatically matches the cable file with historical data, generates handling suggestions, and notifies the maintenance personnel. Maintenance personnel scan the code to view fault information and handling suggestions. After completing the repair, they upload the repair record and acceptance data. The platform automatically updates the cable digital file to achieve closed-loop fault handling. The decommissioning assessment and environmental disposal process includes the following steps: When a cable reaches its designed service life or experiences an irreparable fault, maintenance personnel submit a decommissioning application; the platform retrieves the cable's full life cycle data and assesses the remaining lifespan and insulation aging degree in conjunction with the condition monitoring results; based on the assessment results and in accordance with environmental standards, the platform formulates a disposal plan and records the decommissioning time and disposal method data; after the decommissioning disposal is completed, the relevant data is synchronized to the digital archive to achieve complete retention of the cable's full life cycle data.

[0020] The present invention can achieve the following beneficial effects: 1. This invention uses Ecode128 encoding, which conforms to national standards, as the unique identifier for cables. It combines QR codes with digital character combinations to ensure that information is completely linked in all stages of cable design, production, construction, operation and maintenance to decommissioning, thus completely solving the technical problem of information being scattered and fragmented in the traditional management model.

[0021] 2. This invention enables paperless data collection on-site by scanning codes with mobile terminals, simplifying the operation process, reducing manual input errors, and uploading data to the management platform in real time, thereby achieving instant information sharing and collaborative work, and significantly improving the efficiency of on-site work such as inspection and fault handling.

Detailed Implementation

[0026] Example 1: A method for monitoring the entire lifecycle of power plant cables based on end-to-end identification and mobile terminal scanning is implemented as follows: S1. Perform system architecture design: This invention constructs a four-layer technical architecture of "perception layer - network layer - platform layer - application layer" to realize digital management and control of the entire life cycle of cables from design to decommissioning.

[0027] The perception layer, as the foundational layer of the system, is responsible for the unique identification of cables and the collection of on-site data. It consists of two parts: unified coding and identification carrier deployment.

[0028] The network layer enables data interaction between the perception layer and the platform layer, and adopts a transmission method that combines wireless and wired connections to adapt to the complex field environment of power plants.

[0029] The platform layer serves as the core hub of the system. It is built on the lightweight Spring Boot framework and adopts a front-end and back-end separation design. The back-end integrates Spring MVC and MyBatis-Plus to realize interface development and data persistence, while the front-end uses Vue.js + ECharts to realize visualization.

[0030] At the application level, targeted functional modules are developed for personnel in different positions within the power plant to achieve business digitization at every stage of the entire lifecycle.

[0031] S2. Constructing the perception layer: S2.1 Unified Coding Rules: The Ecode128 general code from GB / T 31866—2023 "IoT Identification System Item Coding Ecode" is adopted as the unique code for each cable item. The total length is 33 decimal digits, and the code structure includes the manufacturer code, model and specification code, production date code, and laying area code.

[0032] S2.2 Identification Carrier Deployment: Select suitable carriers based on the cable laying environment and size characteristics of the power plant. For cables with an outer diameter ≥10mm, a combination of QR codes and numerical characters is used for identification. Cable information is printed directly onto the cable surface using a portable cable marking machine, with markings printed at regular intervals using multi-line printing. For smaller cables, single-line printing is used. All markings are permanently bound to the cable body to ensure identifiability throughout its entire lifecycle.

[0033] S2.3 On-site data acquisition: Through the scanning function of mobile terminals, cable inspection data, status monitoring data, and fault data are collected to achieve paperless and standardized recording of on-site data.

[0034] S3. Network Layer Construction: The network layer enables data interaction between the perception layer and the platform layer, employing a hybrid wireless and wired transmission method. Scanned data collected by the mobile terminal is uploaded to the management platform via 4G / 5G / Wi-Fi / data cable. Among these, 5G, with its high speed, low latency, and wide connectivity, becomes the key bearer network.

[0035] The network layer complies with the network security level protection requirements of GB / T 22239, ensuring the security and reliability of data transmission through encrypted transmission and authorization verification.

[0036] S4. Platform Layer Construction: The platform layer is built on the lightweight Spring Boot framework and adopts a front-end and back-end separation architecture. The back-end integrates Spring MVC and MyBatis-Plus to implement interface development and data persistence, while the front-end uses Vue.js + ECharts for visualization.

[0037] The core functionalities of the platform layer include: S4.1 Data Storage and Management: Establish a full lifecycle database for cables, covering design data (model, cross-section, laying path), production data (factory inspection report, manufacturer information), construction data (laying time, joint manufacturing process, acceptance report), operation and maintenance data (inspection records, condition monitoring data, maintenance records), and decommissioning data (aging degree, disposal plan), to achieve centralized storage, multi-dimensional retrieval, and dynamic updating of data.

[0038] S4.2 Multi-source data fusion: It integrates manual data collected by scanning codes with online monitoring data collected by sensors, and eliminates data redundancy and errors through data cleaning and standardization.

[0039] S4.3 Intelligent Analysis and Early Warning: Based on cable operation data, a condition assessment model and a fault early warning model are constructed. Machine learning algorithms are used to analyze potential hazards such as insulation aging and abnormal temperatures. When monitored indicators exceed thresholds, a tiered early warning is automatically issued, along with the location, type, and handling suggestions of the hazard. Simultaneously, a cable health score (0-100 points) is used to prioritize condition-based maintenance.

[0040] S5. Building the Application Layer: The application layer is designed for different positions in the power plant (planning personnel, construction personnel, operation and maintenance personnel, and management personnel), and develops targeted functional modules to realize the digitalization of business at all stages of the entire life cycle.

[0041] S5.1 Design and Production Management Module: Enables the application, issuance, and assignment of cable codes, binds design parameters and production testing data, forms digital cable archives, and provides a data traceability basis for subsequent stages.

[0042] S5.2 Construction Management Module: Construction personnel can scan codes to complete cable delivery acceptance, laying records, and joint fabrication information uploads. Management personnel can monitor construction progress and quality in real time, and acceptance data is automatically synchronized to the cable digital archive, eliminating hidden construction defects.

[0043] S5.3 Mobile Maintenance Module: Maintenance personnel can quickly query basic cable information and historical records by scanning a code, complete the on-site uploading of inspection data and fault data, and realize closed-loop management of "defect reporting → push maintenance → repair execution → quality acceptance → data archiving".

[0044] S5.4 Status Monitoring and Early Warning Module: Displays cable operating status data and health score in real time, pushes graded early warning information, and supports early warning cause analysis and handling solution query.

[0045] S5.5 Decommissioning Management Module: Based on the cable's entire life cycle data, assess the remaining lifespan and environmental disposal requirements to achieve classified management and disposal plan formulation for decommissioned cables, improve asset utilization, and reduce environmental risks.

[0046] S6. Core Business Process Design: The core business process focuses on achieving deep integration of full-process identification binding and mobile terminal QR code interaction, including four major stages: cable coding and file establishment, QR code construction and acceptance, QR code inspection and fault handling, and decommissioning assessment and disposal.

[0047] 6.1 Cable Coding and Digital File Creation Process: Power plant engineers compile cable lists, confirm the information on the lists, and then apply to the platform for a unified Ecode. The platform automatically generates a unique code and assigns it to the corresponding cable, binding it with detailed cable information, including cable name, cable model, start and end locations, and cable length. Based on the code, the platform automatically creates a digital file for the cable, integrating production and application data to form the foundational data for full lifecycle management.

[0048] 6.2 Construction and Quality Acceptance Process via QR Code: After the cables arrive, construction personnel use a mobile terminal to input the cable's detailed information into a portable cable marking machine, verifying the cable code and parameters. Once confirmed, the corresponding cable is marked throughout the entire process. During laying, construction personnel scan the codes to record data such as laying time, path, and bending radius. After joint fabrication, process parameters and test data are uploaded. After construction is completed, management personnel scan the codes to verify the construction data, complete quality acceptance through on-site testing, and synchronize the acceptance data to the digital archive after passing the acceptance. The cable is then officially put into operation.

[0049] 6.3 QR Code Inspection and Fault Closed-Loop Handling Process: The platform automatically generates an inspection plan based on cable health and laying area and pushes it to the mobile terminals of maintenance personnel. Upon arrival at the site, maintenance personnel scan the QR code to complete the inspection check-in, collect data on cable appearance, temperature, partial discharge, etc., and upload them on-site. If potential hazards are found, a fault is directly reported, noting the type and location of the hazard. Upon receiving the fault information, the platform automatically matches the cable file with historical data, generates handling suggestions, and notifies maintenance personnel. Maintenance personnel scan the QR code to view the fault information and handling suggestions, complete the repair, and upload the repair record and acceptance data. The platform automatically updates the cable digital file, achieving closed-loop fault handling.

[0050] 6.4 Decommissioning Assessment and Environmental Disposal Process: When a cable reaches its designed service life or experiences an irreparable fault, maintenance personnel submit a decommissioning application. The platform retrieves the cable's entire lifecycle data and assesses its remaining lifespan and insulation aging level based on condition monitoring results. Based on the assessment results and environmental standards, the platform develops a disposal plan (resource recovery, hazardous waste treatment, etc.) and records data such as decommissioning time and disposal method. After decommissioning is completed, relevant data is synchronized to the digital archive, achieving complete retention of the cable's entire lifecycle data.
