Abstract
Description
Technical Field
[0001] This invention relates to the field of new energy photovoltaic operation and maintenance technology, specifically to a closed-loop operation and maintenance planning task system for photovoltaic power plants and its execution method. Background Technology
[0002] As the scale of photovoltaic power plants continues to expand, operation and maintenance tasks are becoming increasingly complex, cyclical, and diversified. Currently, the operation and maintenance of photovoltaic power plants generally faces the following problems: (1) The operation and maintenance plan relies more on manual experience and lacks systematic year-round planning; (2) The execution of maintenance tasks is mostly paper-based or scattered records, making it difficult to close the task loop; (3) The annual and monthly inspection plans are disconnected from the actual implementation, and tasks are frequently missed; (4) Operation and maintenance results are difficult to accumulate and cannot form a standardized operation and maintenance management system.
[0003] Therefore, there is an urgent need for a planning and task system that can uniformly plan, intelligently schedule, and manage the annual operation and maintenance tasks of photovoltaic power plants. Summary of the Invention
[0004] To address the aforementioned problems and shortcomings, this invention provides a closed-loop operation and maintenance planning task system and its execution method for photovoltaic power plants, aiming to reduce manual planning costs, minimize manual intervention and misoperation, and achieve traceability and standardized management of operation and maintenance tasks.
[0005] The present invention adopts the following technical solution: On one hand, this invention provides a closed-loop operation and maintenance planning task system for photovoltaic power plants. The system is deployed in an enterprise private cloud environment and adopts a collaborative architecture between a web-based backend and a mobile terminal, including: The task template module, located in the web-based backend, uses standardized task templates to uniformly configure operation and maintenance tasks; The annual plan module, located in the web backend, is used to create an annual operation and maintenance task plan for photovoltaic power plants based on standardized task templates. It automatically obtains the execution date of the task in that year based on the first execution time and task cycle input for the operation and maintenance task. The monthly planning module, located in the web backend, allows users to formulate, supplement, and adjust photovoltaic power plant operation and maintenance tasks for a specified month, with the first day to the last day of the specified month serving as the start and end time of the tasks. The task list module, located in the web-based backend, is used to display the execution status of all tasks. The task triggering module is located in the backend of the web client and is associated with the annual plan module and the monthly plan module. It automatically generates task work orders and pushes them to the mobile client based on the execution dates recorded in the annual plan module and the monthly plan module. The task execution module is located on the mobile device. Operation and maintenance personnel receive the task work orders that need to be executed on the mobile device and submit the task execution results on the mobile device. The task closed-loop management module, located in the web-based backend, is used to analyze the reasons for incomplete tasks and conduct closed-loop review and processing. The task statistics and analysis module, located in the web-based backend, is used to statistically analyze the task completion status of photovoltaic power plants and their operation and maintenance personnel and generate assessment data.
[0006] Furthermore, the task template module uses a standardized task template to uniformly configure each operation and maintenance task, including: task name, task description, task type, device type, task cycle, and task content. The task cycle is the cycle in which the task is triggered, and the task content is the specific work check items that need to be executed for the task. Within the task cycle, the configured task content is sent to the mobile terminal through the task triggering module to generate a task work order.
[0007] More preferably, the task cycle input parameter adopts the N (cycle) + M (number of times) input method.
[0008] Furthermore, the standardized task template in the task template module also includes whether scanning a QR code is required. If scanning a QR code is required, the maintenance personnel need to use a mobile device to scan the QR code on the device to open the task execution status reporting interface.
[0009] Furthermore, the task triggering module has a built-in timed scheduling engine. When the task cycle set in the annual plan set by the annual plan module and the monthly plan set by the monthly plan module reaches the preset time, the corresponding task work order will be automatically generated and the task will be assigned to the operation and maintenance personnel responsible for the corresponding photovoltaic power station and pushed to the operation and maintenance personnel's mobile terminal.
[0010] On the other hand, the present invention also provides a method for executing closed-loop operation and maintenance plan tasks for photovoltaic power plants, comprising the following steps: Standardized task templates are used in the web-based backend to uniformly configure photovoltaic power plant operation and maintenance tasks; Develop annual and monthly operation and maintenance plans in the web-based backend; Based on the annual and monthly operation and maintenance plans, photovoltaic power plant operation and maintenance tasks are triggered on a regular basis, corresponding task work orders are generated, and pushed to the mobile devices of operation and maintenance personnel; Operations and maintenance personnel can view and execute task work orders via mobile devices, and then submit the task execution result form via mobile devices after completion. The web-based backend uses a task execution result form to determine whether the maintenance personnel have exceeded their term. If the task is deemed to have exceeded its time limit, submit a closed-loop application and have it reviewed by the superior. The results of the superior's review will then be written into the task statistics.
[0011] The specific method for maintenance personnel to submit a closed-loop application for overdue task execution and write it into the task statistics based on the superior's review result is as follows: The maintenance personnel responsible for executing the task initiate the closed-loop process through a mobile terminal, fill in the reason for non-completion, and submit it to the superior for review; after the superior's review, if the reason for non-completion is accepted, the task will not be included in the count during statistics, and the task will be closed; if the reason for non-completion is not accepted, the annual or monthly count of uncompleted tasks for the corresponding photovoltaic power station and maintenance personnel will increase by 1, and the task will be closed.
[0012] The present invention has the following advantages over the prior art: A. This invention's system is deployed in an enterprise private cloud environment, utilizing a collaborative model between a web-based backend and a mobile terminal. It establishes embedded modules in the web-based backend, including task templates, annual plans, monthly plans, task triggering, task closed-loop management, and task statistical analysis. It also includes an embedded task execution module on the mobile terminal for maintenance personnel. The task template module standardizes and reuses photovoltaic power plant maintenance tasks, reducing manual planning costs. The annual and monthly plans automatically generate annual and monthly maintenance tasks, reducing manual intervention and improving planning accuracy. It automatically detects incomplete tasks and implements closed-loop management, enhancing the traceability and standardization of maintenance tasks. Furthermore, it provides multi-dimensional task statistical analysis, offering objective data support for power plant maintenance assessment.
[0013] B. The system of the present invention also supports mobile terminal scanning to execute tasks in the task template module, thereby reducing misoperation and improving the accuracy of on-site execution.
[0014] C. The system of this invention abstracts operation and maintenance tasks into task templates, and only "references" the planned tasks without repeating the configuration content. It generates mobile task trigger work orders in a unified manner through the established standard task templates, thereby decoupling the task content from the task scheduling. It has the effect of "configuration in one place, reference in multiple places", improving the system's scalability and adaptability to the scale of photovoltaic power plants.
[0015] D. The present invention is a dynamic triggering algorithm for annual operation and maintenance tasks based on time anchors. It adopts an algorithm that combines the first execution time and the task cycle to automatically calculate the annual execution schedule. This enables the rapid generation of execution plans for different task combinations of power plants. The task cycle input parameter uses N (cycle) + M (number of times) to cover any time cycle scenario. Attached Figure Description

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0021] like Figure 1As shown, this invention provides a closed-loop operation and maintenance planning task system for photovoltaic power plants. The system is deployed in an enterprise private cloud environment and adopts a collaborative architecture of web-based backend and mobile terminal. It includes: a task template module, an annual plan module, a monthly plan module, a task list module, a task trigger module, a task execution module, a task closed-loop management module, and a task statistics and analysis module. The task template module is located in the web-based backend and uses standardized task templates to uniformly configure operation and maintenance tasks. The annual plan module is also located in the web-based backend and formulates the annual operation and maintenance task plan for the photovoltaic power plant based on the standardized task templates. It automatically obtains the task's execution date within the year based on the initial execution time and task cycle input. The monthly plan module is also located in the web-based backend and calculates the execution date for the specified month's photovoltaic power plant operation and maintenance tasks. The photovoltaic power station operation and maintenance tasks are formulated, supplemented, and adjusted, with the first to last day of the specified month as the start and end time of the tasks. The task triggering module is located in the web backend and is associated with the annual plan module and the monthly plan module. Based on the execution dates recorded in the annual plan module and the monthly plan module, it automatically generates task work orders and pushes them to the mobile terminal. The task execution module is located in the mobile terminal, where operation and maintenance personnel receive the task work orders to be executed and submit the task execution results. The preferred mobile terminal is a mobile APP. The task closed-loop management module is located in the web backend and is used to analyze the reasons for incomplete tasks and conduct closed-loop review. The task statistics and analysis module is located in the web backend and is used to statistically analyze the task completion status of photovoltaic power stations and operation and maintenance personnel and generate assessment data.
[0022] The task template module uses standardized task templates to uniformly configure each maintenance task, including: task name, task description, task type, equipment type, task cycle, and task content. Task types are divided into scheduled inspection tasks, routine inspections, and general tasks; equipment types include all equipment types involved in a photovoltaic power station, such as inverters, modules, and transformer substations; the task cycle is the cycle in which the task is triggered; the task content is the specific work inspection items configured for the task, and within the task cycle, the configured task content is sent to the mobile terminal through the task triggering module to generate a task work order. The input format for the task cycle is N (days, months, years) M times; the task content is the specific work inspection items configured for the task, each inspection item including inspection content and data type, where data types include single-line text, multi-line text, single selection, and image capture. The configured task content will generate a task work order when maintenance personnel execute the task using the mobile APP, which is then filled out and submitted by the maintenance personnel. Further options include whether scanning a QR code is required. If scanning is selected, it means that when the task is executed, the maintenance personnel need to use a mobile app to scan the QR code on the device to open the task execution status report interface.
[0023] The annual planning module is located in the web-based backend and is used by operations and maintenance personnel to formulate annual tasks for the power plant. Input fields include year, task type, task name, task cycle, equipment type, power plant to be executed, and the first execution date of the task. Task types are divided into scheduled maintenance tasks, patrol inspection tasks, general tasks, and other tasks. When selecting scheduled maintenance tasks, patrol inspection tasks, or general tasks, the task name can only be selected from the tasks configured in the task template. After selection, the task cycle and equipment type will also be automatically populated from the task template configuration. For other tasks, the equipment type and task cycle must be filled in, and the format should be consistent with the task template. After all content is entered and submitted, the annual planning module will automatically calculate the date that the task needs to be triggered within that year based on the first execution date and task cycle. When that date arrives, the operations and maintenance personnel at the executing power plant will receive a task execution notification on their mobile app.
[0024] The monthly planning module is located in the web-based backend and is used by operations and maintenance (O&M) personnel to create monthly tasks for power plants. Input fields include task type, task name, equipment type, execution time, and the power plant to be executed. Task types are categorized as scheduled maintenance tasks, patrol inspection tasks, general tasks, and other tasks. When selecting scheduled maintenance, patrol inspection, or general tasks, the task name can only be selected from the tasks configured in the task template. After selection, the equipment type will also be automatically populated from the task template configuration. For other tasks, the equipment type must be selected. The execution time is the start and end time of the task; since it's a monthly plan, the maximum span is limited to the first day to the last day of the month. Once all content is entered and submitted, the module will add an O&M task for that month. When the task execution start date arrives, the O&M personnel executing the task will receive a task execution notification on their mobile app.
[0025] The task list module is located in the web-based backend and is primarily used to display the execution status of all tasks. Tasks can be filtered by completion status, photovoltaic power station name, and task time. Clicking on a specific task displays its details, including progress, execution schedule, personnel involved, and results.
[0026] The task triggering module is located in the web backend and has no specific page. This module has a built-in timed scheduling engine. When the task cycle set in the annual plan module or the monthly plan module reaches the preset time, the corresponding task work order will be automatically generated, the task will be assigned to the operation and maintenance personnel responsible for the power station, and the task will be pushed to the operation and maintenance personnel's mobile APP.
[0027] The task execution module is located on the mobile app. When maintenance personnel receive a task notification on the app, they can access the list of tasks to be executed in this module, click on a specific task, and view the task description, the devices involved in the task, and the contents of the task checklist (if it is a QR code scanning task, the app needs to scan the QR code on the device to open the form). After the maintenance personnel complete the on-site execution, they can fill in the task result form in the app and upload data, text content, or on-site photos, etc.
[0028] The task closure management module is located in the web-based backend and is primarily used for the closure management of incomplete tasks. For incomplete tasks, the system defines them as follows: For identical tasks in the annual plan, assuming a total of N trigger times (N > 1), the final completion status of the Mth task (M < N) at 23:59:59 the day before the (M+1)th task is triggered is considered the final completion status of that task. The final completion status of the Nth task at 23:59:59 on December 31st is also considered the final completion status. If a task is triggered only once throughout the year, its final completion status is considered the final completion status of that task at 23:59:59 on December 31st.
[0029] For tasks in the monthly plan, the execution status of the task at 23:59:59 on the actual task deadline day will be taken as its final completion status.
[0030] For incomplete tasks, the maintenance personnel responsible for executing the task need to initiate a closed-loop process, fill in the reason for incompleteness, and submit it to their superiors for review. If the reason is accepted, the task will not be included in the statistics, and the task will be closed; if the reason is not accepted, the annual or monthly count of incomplete tasks for the corresponding power plant and its maintenance personnel will increase by 1, and the task will be closed.
[0031] The task statistics and analysis module is located in the web-based backend. It mainly tracks the actual completion status of closed-loop tasks for each power plant and its maintenance personnel annually and monthly. This statistical data provides a reference for evaluating power plants and maintenance personnel.
[0032] like Figure 2 As shown, the present invention also provides a method for executing closed-loop operation and maintenance plans for photovoltaic power plants, comprising the following steps:

[0033]
S02
[0034]
S03
[0035]
S04
[0036]
S05
[0037] The method of this invention is a decoupling mechanism for operation and maintenance plans and execution based on standard task templates. In traditional operation and maintenance systems, "task content" and "plan scheduling" are often coupled together. Changing one task requires changing multiple plan configurations, making maintenance complex. The system of this invention abstracts operation and maintenance tasks into standard task templates, allowing planned tasks to be "referenced" without repeating configuration content. Mobile forms are generated uniformly through standard task templates, thereby decoupling task content and task scheduling. This achieves the effect of "one configuration, multiple references," improving system scalability and adaptability to power plant scale.
[0038] Furthermore, this invention also incorporates a dynamic triggering algorithm for annual maintenance tasks based on time anchors. Combined with annual plan formulation, it employs an algorithm that integrates the first execution time and task cycle to automatically calculate the annual execution schedule. The task cycle input parameter uses N (cycle) + M (number of times), covering scenarios with any time cycle. Using this algorithm, execution plans for different task combinations in a power plant can be generated rapidly.
[0039] This invention utilizes annual and monthly planning modules to automatically generate annual and monthly maintenance tasks, reducing manual intervention, improving planning accuracy, and automatically detecting incomplete tasks, thereby achieving closed-loop task management and enhancing the traceability and management standardization of maintenance tasks.
[0040] Any aspects not described in this invention are applicable to existing technologies.
[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
