In an alternative embodiment, the first smart device is an ultra-low power wireless fidelity (WiFi) device, and the second smart devices are smart home devices (e.g., wiFi devices such as a smart air conditioner, a smart socket, and a smart light fixture). The generalization of the gateway refers to embedding a module with gateway functions into any intelligent device capable of supplying power normally, so that the intelligent device is newly added with gateway functions based on the original functions. For example: the initial service provided by the intelligent air conditioner is refrigerating or heating service, and the intelligent air conditioner is added with gateway functions based on original functions by embedding the home gateway module into the intelligent air conditioner. For another example: the initial service provided by the intelligent lamp is lighting service, and the intelligent lamp is added with gateway functions based on original functions by embedding the home gateway module into the intelligent lamp.

In this embodiment, a task scheduling processing method running on the first smart device (i.e. workstation) is provided, fig. 1 is a flowchart of a task scheduling processing method according to one embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
step S104, monitoring a beacon frame sent by an access point according to a preset period, wherein the preset period is determined by initial wake-up time of a first part of tasks, and each task in the first part of tasks is a postponable wake-up task;
step S105, under the triggering of the beacon frame, switching from a dormant state to an awake state;
step S106, scheduling and executing the first part of tasks in the wake-up state.
Through the steps, the beacon frame sent by the access point can be intercepted according to the preset period, the preset period is determined by the initial wake-up time of the first partial task, each task in the first partial task is a mode capable of delaying the wake-up task, through switching from the dormant state to the wake-up state under the triggering of the beacon frame and scheduling and executing the first partial task under the wake-up state, the purpose that the processor can be in the dormant state as much as possible through modifying the RTOS system is achieved, so that more power consumption is saved is achieved, the wake-up time of the processor is reduced to the maximum extent, meanwhile, the technical effect that the task processing delay can be reduced is achieved, and the technical problem that the scheduler provided in the related art cannot dynamically control the dormant time according to the system requirement is solved, so that resource waste can be generated in many cases.
In an RTOS system, there is one IDLE (IDLE) task that is responsible for entering and executing IDLE tasks by the scheduler without other tasks needing to be executed. In some systems with low power requirements, the maximum sleep time that can be accepted by all other tasks is calculated in the IDLE task so that the processor can enter the sleep state. The processor needs to be re-awakened and the scheduling system restarted only when the wake-up opportunity is met. However, since the execution process of each task is not synchronized, the sleep start time and the sleep time period for each task cannot be completely determined. For this reason, the processor cannot be in a sleep state for a long time, but is selectively awakened periodically to perform tasks.
Optionally, before listening for the beacon frame sent by the access point according to the preset period in step S104, the following steps may be performed:
and step S100, dividing all tasks to be executed into a first part of tasks and a second part of tasks according to the dormancy type, wherein each task in the second part of tasks is a non-delayed awakening task.
By modifying the RTOS, the sleep type of each task is distinguished, and the sleep type of each task is further divided into non-deferred wakeup (i.e., hard delay) and deferrable wakeup (i.e., soft delay). And then, summarizing all the tasks capable of being awakened after delay, and uniformly calculating to obtain a more reasonable sleep time length, so that the processor is awakened again when the sleep time length is finished, and all the tasks capable of being awakened after delay are completed once. Therefore, a plurality of sleep time fragments can be integrated together, and the processor is prevented from frequently switching between the wake-up state and the sleep state.
Optionally, before listening for the beacon frame sent by the access point according to the preset period in step S104, the following steps may be performed:
step S101, acquiring initial wake-up time of each task in a first part of tasks;
step S102, determining target wake-up time of the first part task based on the initial wake-up time of each task in the first part task, wherein the target wake-up time is used for uniformly scheduling the first part task;
step S103, determining a preset period by adopting the initial wake-up time and the target wake-up time of each task in the first part of tasks.
By acquiring the initial wake-up time of each task in all the deferrable wake-up tasks, a more reasonable target wake-up time for uniformly scheduling all the deferrable wake-up tasks can be uniformly calculated, and therefore the preset period can be determined. FIG. 2 is a schematic diagram of a task scheduling process according to an alternative embodiment of the present invention, as shown in FIG. 2, after the WiFi device turns on the WiFi low-power mode, all deferrable wakeup tasks may include, but are not limited to: task 1, task 2, task 3, task 4, and task 5. Further, task 1, task 2, task 3, task 4, and task 5 have different initial wake-up timings. For example: task 1 has an initial wake up occasion 1, task 2 has an initial wake up occasion 2, task 3 has an initial wake up occasion 3, task 4 has an initial wake up occasion 4, and task 5 has an initial wake up occasion 5. If the WiFi device schedules and executes task 1 at initial wake up occasion 1, schedules and executes task 2 at initial wake up occasion 2, schedules and executes task 3 at initial wake up occasion 3, schedules and executes task 4 at initial wake up occasion 4, and schedules and executes task 5 at initial wake up occasion 5, the WiFi device will frequently switch between the wake up and sleep states. Therefore, by adopting the technical scheme provided by the embodiment of the invention, the WiFi device determines the target wake-up time common to the task 1, the task 2, the task 3, the task 4 and the task 5 based on the initial wake-up time of each task to uniformly schedule and execute the tasks. For example: the WiFi device finds that the initial wake-up time of the task 1 is earliest through comparison, the initial wake-up time of the task 5 is latest, and the initial wake-up time of the other tasks is sequentially centered. To this end, the WiFi device may determine the initial wake-up occasion of task 5 as the target wake-up occasion, and then the WiFi device may maintain the sleep state between initial wake-up occasion 1 and initial wake-up occasion 5 (target wake-up occasion). Therefore, the sleep time between the initial wake-up time 1 and the initial wake-up time 5 is the preset period.
Optionally, in step S106, scheduling and executing the first partial task in the awake state may include the following execution steps:
step S1061, detecting a first part of tasks at a target wake-up opportunity;
step S1062, uniformly scheduling and executing the first part of tasks according to a preset rule, where the preset rule includes one of the following: and sequentially executing the first partial tasks according to the task priority and sequentially executing the first partial tasks in turn.
Since the WiFi device needs to be periodically awakened to receive a beacon frame (beacon) sent by the AP after the WiFi low power mode is turned on, and determine whether there is data to be processed, the awakening period can be adjusted to be the overall duration of all tasks capable of being awakened later. Whereby the RTOS will check synchronously whether there is a task to be performed each time the WiFi device receives a beacon from the AP.
As also shown in fig. 2, the WiFi device switches from the sleep state to the awake state at the target wake-up occasion, and determines that task 1, task 2, task 3, task 4, and task 5 need to be scheduled and executed at the target wake-up occasion. In the actual execution process, the WiFi device may sequentially execute task 1, task 2, task 3, task 4, and task 5 according to the task priority. For example: assuming that the priority of task 2 > the priority of task 1 > the priority of task 3 > the priority of task 5 > the priority of task 4 is determined in accordance with the task priority ranking, the WiFi device will execute task 2, task 1, task 3, task 5 and task 4 in that order. The WiFi device may also perform task 1, task 2, task 3, task 4, and task 5 in turn. For example: task 1, task 2, task 3, task 4 and task 5 are alternately executed in the order of the task numbers from small to large.
Optionally, the method may further include the following steps:
step S107, obtaining an initial wake-up time of each task in the second part of tasks;
step S108, switching from the dormant state to the awake state at regular time based on the initial wake-up time of each task in the second part of tasks;
step S109, scheduling and executing the second partial task in the awake state.
For non-delayed wakeup tasks with very sensitive execution time, because the processing mode of unified scheduling and execution of the deferrable wakeup tasks cannot be adopted, an accurate timing wakeup control mode can be adopted for the non-delayed wakeup tasks, and modification of application logic is avoided. In other words, the WiFi device is switched from the sleep state to the wake state at regular time by a regular wake control mode, and non-delayed wake tasks are scheduled and executed in time in the wake state.
From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus the necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment.
