Problems solved by technology

For example, the static scheduling algorithm is inefficient for non-periodic task processing, and the execution order cannot be changed during operation, so the flexibility is poor
The dynamic scheduling algorithm does not predict the jobs that will arrive, so the predictability of the dynamic scheduling algorithm is poor, and the running overhead is large, and the dynamic algorithm may cause a task to wander between processors multiple times, thus consuming more time
[0004] Aiming at technical problems such as large scheduling overhead when scheduling tasks in the smart home system in related technologies, no technical solutions have been proposed

Abstract

The invention provides a task scheduling method and device of a smart home operating system and a storage medium. The method comprises the steps: determining the priority of a to-be-executed task through a first scheduler according to input parameters, wherein the input parameters comprise at least one of the importance degree of the to-be-executed task, the urgency degree of the to-be-executed task and the task period of the to-be-executed task; according to the priorities of the tasks to be executed, scheduling the to-be-executed tasks in the task queue; and under the condition that the priorities of the first task and the second task are the same, instructing the second scheduler to schedule the first task and the second task according to the deadlines of the first task and the second task, wherein the first task is the task with the highest priority in the task queue, and the second task is the currently executed task. By means of the task scheduling method and device, the technical problem that when tasks are scheduled in a smart home system, the scheduling expenditure is large can be solved, the real-time requirement of the system can be better met, and meanwhile the scheduling expenditure of the system is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a task scheduling method, device, and storage medium for a smart home operating system. Background technique [0002] In the prior art, the smart home operating system mostly adopts an embedded real-time operating system. The task scheduling methods of real-time operating systems are divided into static scheduling algorithms and dynamic scheduling algorithms. The advantage of the static scheduling algorithm is that the running cost is small and the predictability is strong. The dynamic scheduling algorithm only considers the parameters of each job in the currently ready job set to determine the current scheduling sequence, and the dynamic scheduling algorithm is more flexible. [0003] Both static scheduling algorithms and dynamic scheduling algorithms have many disadvantages. For example, the static scheduling algorithm is inefficient for aperiodic task processing, and the ...
