[0024] Embodiment 1

[0025] Figure 1 A flowchart of a method for adjusting interrupt priority is provided for the first embodiment of the present invention. This embodiment is applicable to power dispatching scenarios, especially power dispatching scenarios with high concurrency tasks. The method can be executed by an interrupt priority adjustment method device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0026] S110, obtaining the task priority of the task being executed and the interrupt priority of the interrupt to be executed.

[0027] This solution can be executed by an electric power operating system, which can be an operating system for fault detection and power dispatching in the power system based on the Internet of Things technology. The electric power operating system may include devices such as sensing devices, control devices, and communication devices. The sensing device can be used to obtain the operating status information of the power equipment, the communication device can be used for communication between the sensing device and the control device, and the control device can be used to generate an operation task based on the operating status information of the power equipment obtained by the sensing device, and execute the operation task according to the task priority of the operation task according to the preset scheduling strategy. The control device can also process the interruption according to the interruption priority triggered by the power equipment.

[0028] The power operating system can screen the tasks to be executed and the interrupts to be executed in the current power system, and then obtain the task priority of the task being executed and the interrupt priority of the interrupt to be executed. It can be understood that both the operation task and the interrupt require the power operating system to provide hardware resources such as computing and storage for processing. The difference is that the operation task can usually realize specific functions, such as sensing data acquisition, power distribution and other functions, and the execution of the interrupt is usually in response to emergencies in the power system. In the prior art, the task priority of the operation task is set in the operation task system, and the interrupt priority of the interrupt is set in the interrupt system. Whether it is an operation task or a terminal, its priority setting is usually static, which makes it difficult to balance the operation task and the interrupt, and easily causes resource waste and allocation conflicts.

[0029] S120: Determine a priority adjustment result of the interrupt to be executed according to the task priority and the interrupt priority, so as to process the interrupt to be executed according to the priority adjustment result.

[0030] In this solution, the power operating system can adjust the interrupt priority of the pending interrupt according to the task priority of the task being executed, so that the interrupt processing can be coordinated with the execution of the operation task to avoid resource waste and allocation conflicts. Specifically, the power operating system can determine the adjusted priority of the pending interrupt according to the task priority of the task being executed and the preset interrupt priority of the pending interrupt, that is, the priority adjustment result of the pending interrupt.

[0031] In this solution, determining the priority adjustment result of the interrupt to be executed according to the task priority and the interrupt priority includes:

[0032] The priority adjustment result of the interrupt to be executed is calculated according to the task priority, the interrupt priority and the pre-acquired real-time evaluation factor of the interrupt to be executed.

[0033] It is easy to understand that for the pending interrupt, in addition to associating its priority with the priority of the task being executed, the real-time processing of the pending interrupt should also be guaranteed. Therefore, the power operating system can calculate the priority adjustment result of the pending interrupt according to the task priority of the task being executed, the interrupt priority of the pending interrupt, and the real-time evaluation factor of the pending interrupt. Among them, the real-time evaluation factor can characterize the real-time requirement of the pending interrupt.

[0034] Based on the above solution, the calculation formula of the priority adjustment result of the interrupt to be executed is:

[0035] P i =P base +w1·P task +w2·R i ;

[0036] Among them, P i Indicates the priority adjustment result of the interrupt to be executed, P base Indicates the interrupt priority level of the interrupt to be executed, P task Indicates the task priority of the task being executed, R i It represents the real-time evaluation factor of the interrupt to be executed, w1 and w2 represent the task priority and the weight coefficient of the real-time evaluation factor respectively.

[0037] In this solution, w1+w2=1. By comprehensively considering the real-time nature of the interrupt to be executed and the task priority of the task being executed, the power operating system can adaptively adjust the interrupt priority of the interrupt to be executed, so that interrupt processing can be better coordinated with task execution.

[0038] It should be noted that the task priority of the task being executed can be pre-set, or can be obtained by adjusting at least once based on the pre-set task priority. In a specific example, the power operation system can periodically adjust the task priority of the task being executed in the power operation system to ensure the real-time execution of each operation task. The task priority of the task being executed after adjustment can be expressed as: t ′ ask =P task +w3·I task -w4·R task ; Among them, I task Represents the importance factor of the task being performed, R task Indicates the real-time factor of the task being executed, P taskIndicates the preset task priority of the task being executed. The preset task priority of the task being executed can be set according to the task type of the task being executed. The importance factor of the task being executed can be determined based on the contribution of all the tasks being executed in the power operation system to the power system. The real-time factor of the task being executed can be determined based on the maximum delay time of the task being executed or the periodic demand of the task being executed. The priority adjustment result of the interrupt to be executed can be based on P task It can also be obtained by adjusting based on P t ′ ask Adjusted.

[0039] The technical solution of the embodiment of the present invention obtains the task priority of the task being executed and the interrupt priority of the interrupt to be executed; determines the priority adjustment result of the interrupt to be executed according to the task priority and the interrupt priority, so as to process the interrupt to be executed according to the priority adjustment result. This technical solution solves the problem of unbalanced resource allocation between interrupt processing and execution of operation tasks in the power operation system. By adjusting the interrupt priority based on the operation task priority, interrupt processing can be coordinated with the execution of the operation task, avoiding resource waste and resource allocation conflicts.

[0040] Embodiment 2

[0041] Figure 2 This is a flow chart of a method for adjusting interrupt priority provided by Embodiment 2 of the present invention. This embodiment is refined based on the above embodiment. Figure 2 As shown, the method includes:

[0042] S210. Obtain trigger frequency information of historical interruptions in the power operation system.

[0043] The power operating system can collect historically stored interruption trigger information, count the trigger frequency of each historical interruption, and obtain the trigger frequency information of the historical interruption. The number of historical interruptions can be multiple, and the trigger frequency information can include the trigger frequency of each historical interruption.

[0044] S220: Determine a target interrupt set according to the trigger frequency information of the historical interrupts.

[0045] The trigger frequency of each historical interrupt is compared with a preset frequency threshold, and target interrupts whose trigger frequency is lower than the frequency threshold are screened out from various historical interrupts to form a target interrupt set.

[0046] S230: Obtain interrupt attribute information of each target interrupt in the target interrupt set.

[0047] After obtaining the target interruption set, the power operating system can obtain the interruption attribute information of each target interruption in the target interruption set. The interruption attribute information may include information such as interruption name, interruption type, processing logic, processing time, trigger frequency, and interruption priority; the interruption type may include timer interruption, sensor interruption, and communication interruption; the processing logic may be the execution steps of responding to the target interruption; the processing time may include the average processing time, maximum processing time, or minimum processing time of the target interruption under the historical processing record; the triggering frequency may be the number of triggers within a preset time period, such as the number of triggers within the past month.

[0048] S240 : Determine the similarity between the interrupt to be executed and each target interrupt according to the interrupt attribute information of each target interrupt and the interrupt attribute information of the interrupt to be executed.

[0049] The power operating system can generate a feature vector of the target interruption according to the interruption attribute information of the target interruption, generate a feature vector of the interruption to be executed according to the interruption attribute information of the interruption to be executed, and calculate the distance between the feature vector of the target interruption and the feature vector of the interruption to be executed as the similarity between the interruption to be executed and the target interruption. Specifically, the distance calculation method between the feature vector of the target interruption and the feature vector of the interruption to be executed can be one of the distance calculation methods such as Euclidean distance, Mahalanobis distance and cosine distance.

[0050] In this solution, the interrupt attribute information includes interrupt type, processing time, trigger frequency and interrupt priority;

[0051] The determining, according to the interrupt attribute information of each target interrupt and the interrupt attribute information of the interrupt to be executed, the similarity between the interrupt to be executed and each target interrupt comprises:

[0052] Determine the functional similarity between the interrupt to be executed and each target interrupt according to the interrupt type of each target interrupt and the interrupt type of the interrupt to be executed;

[0053] Determine the time similarity between the interrupt to be executed and each target interrupt according to the processing time of each target interrupt and the processing time of the interrupt to be executed;

[0054] Determine the similarity between the trigger frequency of the interrupt to be executed and the trigger frequency of each target interrupt according to the trigger frequency of each target interrupt and the trigger frequency of the interrupt to be executed;

[0055] Determine the similarity between the priority of the interrupt to be executed and that of each target interrupt according to the interrupt priority of each target interrupt and the interrupt priority of the interrupt to be executed;

[0056] The similarity between the interrupt to be executed and each target interrupt is determined according to the functional similarity, time similarity, trigger frequency similarity and priority similarity between the interrupt to be executed and each target interrupt.

[0057] Based on the above scheme, the similarity calculation formula between the interrupt to be executed and the target interrupt can be expressed as:

[0058] S(i,j)=α·C(i,j)+β·T(i,j)+γ·F(i,j)+δ·P(i,j);

[0059] Where, C(i,j) represents functional similarity, T(i,j) represents temporal similarity, F(i,j) represents trigger frequency similarity, P(i,j) represents priority similarity, i represents the interrupt index to be executed, j represents the target interrupt index, α, β, γ and δ are weight coefficients of functional similarity, temporal similarity, trigger frequency similarity and priority similarity respectively; C(i,j) is 0 or 1, 1 represents the same, 0 represents different;

[0060] The calculation formula of time similarity can be expressed as:

[0061]

[0062] Among them, 0≤T(i,j)≤1, T i represents the average processing time of the pending interrupt i, T j represents the average processing time of target interrupt j;

[0063] The calculation formula of trigger frequency similarity can be expressed as:

[0064]

[0065] Among them, 0≤F(i,j)≤1, F i Indicates the trigger frequency of the interrupt i to be executed; F j Indicates the trigger frequency of target interrupt j;

[0066] The calculation formula of priority similarity can be expressed as:

[0067]

[0068] Among them, 0≤P(i,j)≤1, ΔP=|P i -P j |, where P i Indicates the interrupt priority of the interrupt i to be executed; P j represents the interrupt priority of target interrupt j; ΔP represents the priority difference.

[0069] This scheme evaluates the similarity between interruptions from multiple dimensions, which is conducive to ensuring the reliability and stability of the similarity.

[0070] S250: Determine whether the similarity between the interrupt to be executed and each target interrupt is less than a preset similarity threshold.

[0071] It can be understood that the power operating system can use a preset similarity threshold to determine whether the interrupt to be executed is the same or similar to each target interrupt in the target interrupt set. If the similarity between the interrupt to be executed and each target interrupt is less than the preset similarity threshold, it means that the interrupt to be executed is neither the same nor similar to each target terminal, that is, the interrupt to be executed is not an interrupt with a low trigger frequency, and the power operating system can execute S270. If the similarity between the interrupt to be executed and at least one target interrupt is greater than or equal to the preset similarity threshold, it means that the interrupt to be executed is the same or similar to at least one target interrupt in the target interrupt set, then the interrupt to be executed is an interrupt with a low trigger frequency, and the power operating system can execute S260.

[0072] S260: Aggregate the interrupts to be executed according to the preset time window.

[0073] If the interrupt to be executed is a low trigger frequency interrupt, the power operating system can collect the low trigger frequency interrupts in the same time window according to the preset time window, and centrally process the collected multiple low trigger frequency interrupts to avoid the low trigger frequency interrupts interfering with the execution of the operation task.

[0074] S270 , determining a priority adjustment result of the interrupt to be executed according to the interrupt priority of the interrupt to be executed and the task priority of the task being executed.

[0075] If the pending interrupt is not an interrupt with a low trigger frequency, the power operating system can adjust the interrupt priority of the pending interrupt according to the task priority of the task being executed, so as to coordinate the execution order of the two when the pending interrupt conflicts with the task being executed. When the pending interrupt is more urgent than the task being executed, the processing of the task being executed is suspended and the pending interrupt is processed in time. When the task being executed is more urgent than the pending interrupt, the task being executed is continued and the pending interrupt is not responded to for the time being.

[0076] For example, the sensing device in the power operation system detects that a power line fault has occurred in the target area and sends a fault signal. If the priority of the fault detection interrupt is higher than the task priority of the task being executed, the task being executed (such as daily monitoring data recording) can be immediately suspended to handle the fault detection interrupt. The power operation system can take emergency measures in a timely manner to quickly locate and isolate faults, thereby improving the real-time response capability of the power system and avoiding the expansion of faults. During peak power consumption periods, the power grid needs to adjust the allocation of power resources based on the operating status data of the power equipment obtained in real time by the sensing device. If an equipment status report interruption occurs when executing a power dispatching task, the interruption priority of the power dispatching task is higher than the equipment status report interruption. The power dispatching system can give priority to the power dispatching task and suspend the response to the equipment status report interruption to ensure that the power system can quickly adjust power resources, optimize dispatching and allocation, and maintain power supply balance.

[0077] The technical solution of the embodiment of the present invention obtains the task priority of the task being executed and the interrupt priority of the interrupt to be executed; determines the priority adjustment result of the interrupt to be executed according to the task priority and the interrupt priority, so as to process the interrupt to be executed according to the priority adjustment result. This technical solution solves the problem of unbalanced resource allocation between interrupt processing and execution of operation tasks in the power operation system. By adjusting the interrupt priority based on the operation task priority, interrupt processing can be coordinated with the execution of the operation task, avoiding resource waste and resource allocation conflicts.

[0083] The priority adjustment result of the interrupt to be executed is calculated according to the task priority, the interrupt priority and the pre-acquired real-time evaluation factor of the interrupt to be executed.

[0084] Based on the above solution, the calculation formula of the priority adjustment result of the interrupt to be executed is:

[0085] P i =P base +w1·P task +w2·R i ;

[0086] Among them, P i Indicates the priority adjustment result of the interrupt to be executed, P base Indicates the interrupt priority level of the interrupt to be executed, P task Indicates the task priority of the task being executed, R i It represents the real-time evaluation factor of the interrupt to be executed, w1 and w2 represent the task priority and the weight coefficient of the real-time evaluation factor respectively.

[0093] If the similarity between the interrupt to be executed and at least one target interrupt is greater than or equal to a preset similarity threshold, determining a priority adjustment result of the interrupt to be executed according to the task priority and the interrupt priority;

[0094] If the similarity between the interrupt to be executed and each target interrupt is less than a preset similarity threshold, the interrupt to be executed is aggregated according to a preset time window.
