Description

Technical Field

[0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a task execution method, apparatus, storage medium, and intelligent substation area terminal. Background Art

[0002] With the development of smart grids, intelligent substation area terminals play an increasingly important role in the distribution network. This terminal needs to process a large amount of real-time data and execute various functions such as power quality monitoring, fault detection and location, and load management. To support these functions, more and more application programs are integrated into the intelligent substation area terminal to provide a convenient operation interface and enhanced function modules. Therefore, how to efficiently execute the tasks of these application programs is particularly crucial.

[0003] Currently, existing task execution methods usually rely on simple priority or first-come, first-served principles. This method may perform well when the number of application programs is small or resources are sufficient, but when multiple application programs are running simultaneously, existing methods are difficult to evaluate the resource consumption characteristics of each application program, resulting in unbalanced resource allocation and thus affecting the operation efficiency of the intelligent substation area terminal.

[0004] Therefore, there is an urgent need to propose a new method to solve the above problems. Summary of the Invention

[0005] The present invention provides a task execution method, apparatus, storage medium, and intelligent substation area terminal, which can better evaluate the load conditions of each application program, determine target execution tasks based on the load conditions of each application program, thereby avoiding unbalanced resource allocation and improving the operation efficiency of the intelligent substation area terminal.

[0036] In the description of the present application, unless otherwise specified, the meaning of "a plurality of" refers to two or more.

[0037] Figure 1 FIG. is a flowchart of a task execution method provided for an embodiment of the present invention. This embodiment is applicable to the situation where an intelligent substation terminal avoids resource allocation imbalance when multiple application programs are running concurrently. This method can be executed by a task execution device, which can be implemented in a hardware / software manner. The device can be integrated into the intelligent substation terminal. As Figure 1 shown, the specific steps are as follows:

[0038] Step 110: Obtain each task to be executed assigned to the target communication port of the intelligent substation terminal from the task allocation table of the intelligent substation terminal, and determine the application programs assigned to each task to be executed from the application programs installed in the intelligent substation terminal, so as to obtain each candidate application program.

[0039] Specifically, the intelligent substation terminal refers to an intelligent device used for substation management in the power system, which can realize various functions such as data acquisition, transmission, processing and communication with other devices. It can install multiple application programs to execute different tasks and is the core carrier of the entire task execution process. The task allocation table refers to a data structure or database table used to store and manage the information of each task to be executed in the intelligent substation terminal, including the corresponding relationship between the task to be executed and the communication port and the corresponding relationship between the task to be executed and the application program. The target communication port refers to a specific port determined according to the actual situation or requirements in the intelligent substation terminal for executing the target task. The task to be executed refers to the task waiting to be executed in the intelligent substation terminal, which is generated by the application programs installed in the intelligent substation terminal. The application program refers to a software program installed on the intelligent substation terminal that can realize specific functions (such as data acquisition). The candidate application program refers to the program screened from all the application programs installed in the intelligent substation terminal according to the task to be executed.

[0040] In specific implementation, based on the port number of the target communication port, each task to be executed assigned to the target communication port can be filtered out from the task allocation table of the intelligent substation area terminal, and then based on the identity identification numbers of each task to be executed, the identity identification numbers of the matching application programs can be filtered out from the task allocation table. Finally, according to the determined identity identification numbers of the application programs, the application programs assigned to each task to be executed are determined from the application programs installed on the intelligent substation area terminal, and each candidate application program is obtained.

[0041] In this embodiment, by obtaining each candidate application program, a data basis is provided for determining and calculating the load level of each candidate application program later.

[0042] Step 120: Calculate the load level of each candidate application program according to the minimum number of processing tasks, the maximum number of processing tasks, and the number of tasks in execution of each candidate application program.

[0043] Specifically, the minimum number of processing tasks refers to the minimum number of tasks that the application program can process simultaneously set in advance according to the actual situation or requirements. The maximum number of processing tasks is the maximum number of tasks that the application program can process simultaneously set in advance according to the actual situation or requirements. The number of tasks in execution refers to the number of tasks that the application program is currently executing. The load level refers to a quantitative index calculated through the minimum number of processing tasks, the maximum number of processing tasks, and the number of tasks in execution of the application program, which is used to measure the busyness degree and resource utilization of the application program and reflects the resource consumption characteristics of the application program.

[0044] In specific implementation, for the current candidate application program, the load level of the current candidate application program = (the number of tasks in execution of the current candidate application program - the minimum number of processing tasks of the current candidate application program) / (the maximum number of processing tasks of the current candidate application program - the minimum number of processing tasks of the current candidate application program).

[0045] In this embodiment, calculating the load level of each candidate application program according to the minimum number of processing tasks, the maximum number of processing tasks, and the number of tasks in execution of each candidate application program can better evaluate the resource consumption characteristics of each candidate application program and provide a data basis for determining the target application program later.

[0046] Step 130: Determine the candidate application program with the lowest load level as the target application program, and determine the target task from the tasks to be executed of the target application program according to the priorities of the tasks to be executed of the target application program.

[0047] Specifically, the target application refers to the application with the lowest load level selected from each candidate application. The target task refers to the task to be currently executed selected from the tasks to be executed of the target application according to the priority of the task. The priority of the task to be executed refers to an importance identifier set in advance for each task to be executed according to the actual situation or requirements.

[0048] In specific implementation, after obtaining the load levels of each candidate application, the candidate application with the lowest load level can be determined as the target application, and then, among the tasks to be executed corresponding to the target application, the task to be executed with the highest priority is determined as the target task.

[0049] In this embodiment, by selecting the application with the lowest load as the target application, the problem of a single application being overloaded and the resulting imbalance in terminal resource allocation is avoided, thereby improving the overall operating efficiency of the terminal and achieving the optimization of load balancing and resource utilization. At the same time, determining the target task from the tasks to be executed of the target application according to the priority ensures the timely completion of critical tasks and further improves the responsiveness and reliability of the system.

[0050] Step 140: Control the target application to execute the target task through the target communication port.

[0051] In specific implementation, after determining the target task, a connection can be established between the target application and the target communication port according to the configuration information of the target communication port (such as port number, protocol type, etc.). Then, the detailed parameters of the target task (such as execution conditions, input data, etc.) are extracted from the task allocation table, and finally, the task parameters are passed to the target application through the target communication port. After receiving the task parameters, the target application executes the target task.

[0052] In this embodiment, through the above steps, the phenomenon of blind resource invocation and waste is eliminated, the situation of resource idleness or over-occupation is effectively avoided, and the resource utilization rate is significantly improved.

[0053] In the embodiment of the present invention, first, each to-be-executed task assigned to the target communication port of the intelligent substation area terminal is obtained from the task assignment table of the intelligent substation area terminal, and the application programs assigned to each to-be-executed task are determined from the application programs installed in the intelligent substation area terminal, obtaining each candidate application program, which provides a data basis for determining the load level of each candidate application program later. Then, the load level of each candidate application program is calculated according to the minimum number of processing tasks, the maximum number of processing tasks, and the number of tasks in execution of each candidate application program, which can better evaluate the resource consumption characteristics of each candidate application program and provides a data basis for determining the target application program later. After that, the candidate application program with the lowest load level is determined as the target application program, and the target task is determined from the to-be-executed tasks of the target application program according to the priority of the to-be-executed tasks of the target application program, avoiding the problem of a single application program being overloaded and the resulting imbalance in terminal resource allocation, thereby improving the overall operation efficiency of the terminal and realizing the optimization of load balancing and resource utilization rate. At the same time, determining the target task from the to-be-executed tasks of the target application program according to the priority ensures that critical tasks are completed in a timely manner, further improving the responsiveness and reliability of the system. Finally, the target application program is controlled to execute the target task through the target communication port, eliminating the phenomenon of blind resource invocation and waste, effectively avoiding the situation of resource idleness or over-occupation, significantly improving the resource utilization rate, and solving the problem that it is difficult to evaluate the resource consumption characteristics of each application program in the prior art, resulting in an imbalance in resource allocation and thus affecting the operation efficiency of the intelligent substation area terminal.

[0054] Figure 2 FIG. 4 is a flowchart of another task execution method provided by an embodiment of the present invention. This embodiment is a specific implementation based on the above embodiment. In this embodiment, the method may further include:

[0055] Step 210: Obtain each to-be-executed task assigned to the target communication port of the intelligent substation area terminal from the task assignment table of the intelligent substation area terminal.

[0056] Step 211: Determine whether there are immediate execution tasks and important execution tasks among the to-be-executed tasks.

[0057] If there are immediate execution tasks and important execution tasks among the to-be-executed tasks, step 212 is executed; if there are no immediate execution tasks and important execution tasks among the to-be-executed tasks, step 215 is executed.

[0058] Specifically, an immediate execution task refers to a task that needs to be executed immediately and cannot be delayed. For example: The immediate execution task can be an agent transmission task. An important execution task refers to a task that needs to be executed preferentially. For example: The important execution task can be a real-time point reading task.

[0059] In a specific implementation, after obtaining each task to be executed, it is possible to determine whether there are immediate execution tasks and important execution tasks among the tasks to be executed according to the attribute information of each task to be executed (such as the business type). For example: If the business type of the immediate execution task is proxy transmission, the business type of the important execution task is real-time point reading, and there are no tasks to be executed with business types of real-time point reading and proxy transmission among the business types of each task to be executed, it is determined that there are no immediate execution tasks and important execution tasks among the tasks to be executed.

[0060] Step 212: Determine whether there are immediate execution tasks among the tasks to be executed.

[0061] If there are immediate execution tasks among the tasks to be executed, execute step 214; if there are no immediate execution tasks among the tasks to be executed, execute step 213.

[0062] In a specific implementation, after determining that there are no immediate execution tasks and important execution tasks among the tasks to be executed, it is possible to determine whether there are immediate execution tasks among the tasks to be executed according to the attribute information of each task to be executed (such as the business type).

[0063] For example: Assume that the business type of the immediate execution task is proxy transmission, and the business type of the important execution task is real-time point reading. When there is a task to be executed with a business type of proxy transmission among the business types of each task to be executed, it can be determined that there are immediate execution tasks among the tasks to be executed. When there are tasks to be executed with business types of both real-time point reading and proxy transmission among the business types of each task to be executed, it can be determined that there are immediate execution tasks among the tasks to be executed.

[0064] Step 213: Determine the important execution task as the target task.

[0065] In a specific implementation, after determining that there are no immediate execution tasks among the tasks to be executed, the important execution task can be determined as the target task. Then, it is possible to control the target application program to execute the target task through the target communication port, ensuring that high-priority tasks (i.e., important execution tasks) are executed first, avoiding low-priority tasks from over-occupying resources and causing high-priority tasks to be unable to be executed in a timely manner, effectively improving the stability of the system.

[0066] Optionally, after determining the important execution task as the target task, it is possible to first determine whether there is available capacity in the task pool of the target application program. If there is available capacity in the task pool, put the target task into the task pool and control the target application program to execute the target task through the target communication port. If there is no available capacity in the task pool, monitor the capacity of the task pool until there is available capacity in the task pool, then put the target task into the task pool and control the target application program to execute the target task through the target communication port.

[0067] Step 214: Determine the task to be executed immediately as the target task.

[0068] In specific implementation, after determining that there is a task to be executed immediately among the tasks to be executed, the task to be executed immediately can be determined as the target task. Then, it is possible to control the target application program to execute the target task through the target communication port, ensuring that the task to be executed immediately can be processed in a timely manner.

[0069] Furthermore, after determining the task to be executed immediately as the target task, it further includes: determining whether there is available capacity in the task pool of the target application program; if there is available capacity in the task pool, putting the target task into the task pool of the target application program, and controlling the target application program to execute the target task through the target communication port; if there is no available capacity in the task pool, suspending the task with the lowest priority in the task pool, putting the target task into the task pool of the target application program, and controlling the target application program to execute the target task through the target communication port.

[0070] Specifically, the task pool refers to the area in the application program for storing target tasks.

[0071] In specific implementation, after determining the task to be executed immediately as the target task, the total capacity information and the used capacity information of its task pool can be obtained through the interface of the target application program, and then, based on the difference between the total capacity and the used capacity, it is determined whether there is available capacity in the task pool of the target application program. If there is available capacity in the task pool, put the target task into the task pool of the target application program, and control the target application program to execute the target task through the target communication port. If there is no available capacity in the task pool, traverse all the tasks in the task pool to find the task with the lowest priority, remove the task from the task pool, and set its status to "suspended". Then, put the target task into the task pool, and control the target application program to execute the target task through the target communication port.

[0072] In this embodiment, through the above steps, the priority status of the task to be executed immediately is clarified. Whether there is available capacity in the task pool or not, the system will give priority to putting the task to be executed immediately into the task pool and executing it as soon as possible. Especially when the task pool capacity is insufficient, the system will suspend low-priority tasks to ensure that the task to be executed immediately can obtain the execution opportunity first. It avoids the situation that the task to be executed immediately cannot be processed due to the full task pool, effectively prevents low-priority tasks from occupying too many resources, resulting in the task to be executed immediately waiting for a long time or even unable to execute, thereby improving the overall stability, reliability, and real-time performance of the system, and ensuring that high-priority tasks can respond and execute quickly.

[0073] Step 215: Determine the application programs assigned to each task to be executed from the application programs installed on the intelligent substation area terminal to obtain each candidate application program.

[0074] Step 216: Calculate the load level of each candidate application according to the minimum number of processing tasks, the maximum number of processing tasks, and the number of tasks in execution of each candidate application.

[0075] In one implementation, step 216 may specifically include: for the current candidate application, when the number of tasks in execution of the current candidate application is less than the minimum number of processing tasks of the current candidate application, the ratio of the number of tasks in execution to the minimum number of processing tasks is determined as the load level of the current candidate application; when the number of tasks in execution is not less than the minimum number of processing tasks but not greater than the maximum number of processing tasks of the current candidate application, calculate the difference between the number of tasks in execution and the minimum number of processing tasks to obtain the current task deviation, calculate the difference between the maximum number of processing tasks and the minimum number of processing tasks to obtain the current task processing capacity difference, and determine the ratio of the current task deviation to the current task processing capacity difference as the load level of the current candidate application; when the number of tasks in execution is greater than the maximum number of processing tasks, calculate the difference between the number of tasks in execution and the maximum number of processing tasks to obtain the current task excess, and determine the ratio of the current task excess to the maximum number of processing tasks as the load level of the current candidate application.

[0076] Specifically, the current minimum number of processing tasks refers to the minimum number of processing tasks of the current candidate application. The number of tasks in execution refers to the number of tasks in execution of the current candidate application. The current maximum number of processing tasks refers to the maximum number of processing tasks of the current candidate application. The current task deviation refers to the difference between the number of tasks in execution and the minimum number of processing tasks. The current task processing capacity difference refers to the difference between the maximum number of processing tasks and the minimum number of processing tasks. The current task excess refers to the difference between the number of tasks in execution and the maximum number of processing tasks.

[0077] Exemplarily, for the current candidate application, assume that the current minimum number of processing tasks is P, the number of tasks in execution is T, and the current maximum number of processing tasks is Q. When T < P, the load level of the current candidate application is T / P. When P ≤ T ≤ Q, the current task deviation is T - P, the current task processing capacity difference is Q - P, and the load level of the current candidate application is (T - P) / (Q - P). When T > Q, the current task excess is T - Q, and the load level of the current candidate application is (T - Q) / Q.

[0078] In this embodiment, through the above steps, the accuracy of the determined load level is improved.

[0079] Step 217: Determine the candidate application with the lowest load level as the target application, and determine the target task from the tasks to be executed of the target application according to the priority of the tasks to be executed of the target application.

[0080] Further, determining the target task from the tasks to be executed of the target application according to the priority of the tasks to be executed of the target application includes: screening out the highest priority from the priorities of each task to be executed to obtain the target priority; determining whether there are at least two tasks to be executed with the target priority; if so, determining the target task from at least two tasks to be executed with the target priority according to the timestamp of the tasks to be executed; if not, determining the task to be executed with the target priority as the target task.

[0081] Specifically, the target priority refers to the highest priority screened out from the priorities of each task to be executed.

[0082] In specific implementation, after determining the target application, the highest priority can be screened out from the priorities of each task to be executed first as the target priority. Then determine whether there are at least two tasks to be executed with the target priority; if so, determine the task to be executed with the earliest timestamp among the tasks to be executed with the target priority as the target task; if not, determine the only task to be executed with the target priority as the target task.

[0083] In this embodiment, through the above steps, it can be ensured that high-priority tasks are executed first, and when multiple tasks have the same highest priority, the task with the earliest timestamp will be selected to ensure that the task that arrives first is executed first, thus avoiding long waiting times for tasks.

[0084] Further, after determining the target task from the tasks to be executed of the target application according to the priority of the tasks to be executed of the target application, it further includes: determining whether there is available capacity in the task pool of the target application; if there is available capacity in the task pool, put the target task into the task pool; if there is no available capacity in the task pool, monitor the capacity of the task pool until there is available capacity in the task pool, and then put the target task into the task pool.

[0085] In a specific implementation, after determining a target task from the tasks to be executed of a target application according to the priority of the tasks to be executed of the target application, the total capacity information and the used capacity information of its task pool can be obtained through the interface of the target application, and then, based on the difference between the total capacity and the used capacity, it is determined whether there is available capacity in the task pool of the target application. If there is available capacity in the task pool, the target task is placed into the task pool of the target application. If there is no available capacity in the task pool, a monitoring mechanism (such as periodic polling, event-driven, etc.) can be started to monitor the capacity of the task pool until there is available capacity in the task pool, and then the target task is placed into the task pool.

[0086] In this embodiment, through the above steps, it can be ensured that the target task can enter the task pool and be executed in a timely manner. When there is available capacity in the task pool, the target task will be immediately incorporated, thus making full use of the task pool resources and avoiding the idle waste of resources. If the task pool is full, by continuously monitoring the capacity of the task pool and waiting for a task to be completed to release available capacity, it not only prevents resources from being occupied by unnecessary tasks, ensures that the task pool is always in a highly efficient utilization state, but also avoids the occurrence of overload situations.

[0087] Step 218: Control the target application to execute the target task through the target communication port.

[0088] Therefore, in the technical solution of the present invention, each to-be-executed task assigned to the target communication port of the intelligent substation area terminal is first obtained from the task assignment table of the intelligent substation area terminal, and then it is determined whether there are immediate execution tasks and important execution tasks among the to-be-executed tasks. If there are immediate execution tasks and important execution tasks among the to-be-executed tasks, it is determined whether there are immediate execution tasks among the to-be-executed tasks. If there are immediate execution tasks among the to-be-executed tasks, the immediate execution tasks are determined as target tasks, and then the target application is controlled to execute the target tasks through the target communication port, ensuring that the immediate execution tasks can be processed in a timely manner. If there are no immediate execution tasks among the to-be-executed tasks, the important execution tasks are determined as target tasks, and then the target application is controlled to execute the target tasks through the target communication port, ensuring that high-priority tasks (i.e., important execution tasks) are executed first, avoiding low-priority tasks from occupying too many resources and causing important tasks to be unable to be executed in a timely manner, thereby improving the overall stability. If there are no immediate execution tasks and important execution tasks among the to-be-executed tasks, the application programs assigned to the to-be-executed tasks are determined from the application programs installed on the intelligent substation area terminal to obtain each candidate application program, providing a data basis for subsequently determining and calculating the load levels of the candidate application programs. Then, according to the minimum number of processing tasks, the maximum number of processing tasks, and the number of tasks in execution of each candidate application program, the load levels of the candidate application programs are calculated, which can better evaluate the resource consumption characteristics of each candidate application program and provide a data basis for subsequently determining the target application program. Subsequently, the candidate application program with the lowest load level is determined as the target application program, and the target tasks are determined from the to-be-executed tasks of the target application program according to the priorities of the to-be-executed tasks of the target application program, avoiding the problem of a single application program being overloaded and the resulting imbalance in terminal resource allocation, thereby improving the overall operation efficiency of the terminal and achieving the optimization of load balancing and resource utilization rate. At the same time, determining the target tasks from the to-be-executed tasks of the target application program according to the priorities ensures the timely completion of critical tasks and further improves the responsiveness and reliability of the system. Finally, the target application is controlled to execute the target tasks through the target communication port, eliminating the phenomenon of blind resource invocation and waste, effectively avoiding the situation of resource idleness or over-occupation, significantly improving the resource utilization rate, and solving the problem in the prior art that it is difficult to evaluate the resource consumption characteristics of each application program, resulting in resource allocation imbalance and further affecting the operation efficiency of the intelligent substation area terminal.
