Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
One aspect of embodiments of the present invention provides a method for allocating time slices for a task. FIG. 1 is a flow diagram of a method for allocating time slices for a task according to an embodiment of the present invention. As shown in fig. 1, the method includes the following.
In step S10, the state of each of at least one task is determined at predetermined time intervals. The state of the task may include an idle state and a non-idle state, among others. Alternatively, in the embodiment of the present invention, the predetermined time interval may be 1 ms.
In step S11, the time slices are allocated according to the determination. Specifically, the following may be included. In at least one task, a preset idle time slice is respectively allocated to the tasks in the idle state. The preset idle time slices allocated to each task whose state is idle state may be the same or different. In addition, the smaller the preset idle time slice is, the less system resources of the processor are occupied when the task is idle, the less the waste of the system resources of the processor is, and the more the execution efficiency of the task can be improved. Alternatively, each task may be assigned a 1ms time slice when the state is idle. In at least one task, allocating preset non-idle time slices for the tasks in the non-idle state respectively, wherein the preset time interval is smaller than the preset non-idle time slices allocated for the tasks in the non-idle state respectively, and the preset idle time slices allocated for each task in the at least one task in the idle state are smaller than the preset non-idle time slices allocated for the tasks in the non-idle state. The preset non-idle time slices allocated to the tasks in the non-idle state may be the same or different. Specifically, the preset non-idle time slice to which each task is allocated when the state is the non-idle state may be determined based on hardware for executing the task, a condition of the task, and a communication timing. In addition, the time interval (the predetermined time interval) for re-determining the state of each task in the at least one task is smaller than the preset non-idle time slice allocated to each task in the at least one task when the state is the non-idle state. And the time slice allocated to each task when the state is the idle state is smaller than the time slice allocated to each task when the state is the non-idle state. In addition, the relationship between the time slice allocated to each task when the state is the idle state and the time slices allocated to other tasks when the state is the non-idle state is not determined, and may be determined according to specific situations.
The time slices are allocated to the tasks according to the states of the tasks, and the time slices allocated when the tasks are in the idle state are smaller than the time slices allocated when the tasks are in the non-idle state, so that compared with the time slices allocated when the tasks are in the non-idle state no matter what states the tasks are in, occupation of system resources is reduced, waste of the system resources of the processor is reduced, execution efficiency of the tasks is improved, especially the execution efficiency is improved under the multi-task condition, and better experience is brought to users.
For example, the distribution time slice will be described with reference to fig. 2 by taking an intelligent door lock as an example. Suppose that the intelligent door lock needs to execute a screen control task, a voice broadcast task, a safety management task, a motor control task and a message report task at most, and the total tasks are five tasks. The method for allocating a time slice to a task according to the embodiment of the present invention corresponds to a timer interrupt procedure, for example, a timing interval is 1ms, and the method according to the embodiment of the present invention corresponds to a 1ms timer interrupt procedure, and a timer is set to detect time. As shown in fig. 2, the timer enters an interrupt routine every 1ms, and the interrupt routine is used to query the status of each task, and further allocate a time slice to each task according to the status of each task. When tasks do not need to be executed (i.e., idle state), each task is assigned a 1ms time slice to reduce the loss of system resources. When the task needs to be executed (namely, the task is in a non-idle state), 2ms, 3ms, 5ms, 2ms and 3ms time slices are respectively allocated to the screen control task, the voice broadcasting task, the safety management task, the motor control task and the message reporting task. The time slice allocated to each task may be the same as or different from the hardware for executing the task, the task condition and the communication timing sequence, which is only an example, and how many time slices are specifically allocated to the non-idle state may be determined according to the actual situation.
FIG. 3 is a logic diagram illustrating the assignment of time slices to tasks according to another embodiment of the present invention. In this embodiment, it is assumed that the intelligent door lock needs to execute at most five tasks, namely, a screen control task, a voice broadcast task, a security management task, a motor control task, and a message report task, and how to allocate a time slice to a task in the process of password modification is described with reference to the time slice allocation shown in fig. 2 by taking the password modification of the intelligent door lock as an example. Wherein the predetermined time interval is 1ms, that is, the status of the task is determined once every 1 ms. Further, in this embodiment, "execution required" corresponds to the idle state described in the embodiment of the present invention, and "execution not required" corresponds to the non-idle state. Assume that the intelligent door lock is in an idle state (each task is allocated with only 1ms time slice, and the time for the control system of the intelligent door lock to execute a large cycle is only 5 ms). At this time, if the user wants to modify the password, firstly, the 1ms timer interrupt program judges that the screen control task and the voice broadcast task need to be executed, and other tasks do not need to be executed. The time slices allocated for the screen control task and the voice broadcasting task are respectively modified into 2ms and 3ms, and the time slices of other tasks are not changed (the time for the control system of the intelligent door lock to execute the major cycle is 8 ms). And the user modifies the unlocking password through the screen terminal according to the voice prompt. Subsequently, the 1ms timer judges that the screen control task and the voice broadcast task do not need to be executed, the safety management task does not need to be executed, other tasks do not need to be executed, the time slices of the screen control task, the voice broadcast task and the safety management task are respectively modified into 1ms, 1ms and 5ms, and the time slices of the other tasks are not changed (the time for the control system of the intelligent door lock to execute the major cycle is 9 ms). And saving the unlocking password modified by the user. The 1ms timer judges that the safety management task does not need to be executed and other tasks do not need to be executed, the time slice of the safety management task is modified into 1ms, the time slices of the other tasks are unchanged (the time for the control system of the intelligent door lock to execute the major cycle is 5ms), the system resources are released, and each task returns to the original idle state.
FIG. 4 is a logic diagram illustrating the assignment of time slices to tasks according to another embodiment of the present invention. In this embodiment, it is assumed that the intelligent door lock needs to execute at most five tasks, namely, a screen control task, a voice broadcast task, a security management task, a motor control task, and a message report task, and how to allocate a time slice to a task in the unlocking process is described with reference to the allocation time slice shown in fig. 2 by taking the modification of a password for the intelligent door lock as an example. Wherein the predetermined time interval is 1ms, that is, the status of the task is determined once every 1 ms. Further, in this embodiment, "execution required" corresponds to the idle state described in the embodiment of the present invention, and "execution not required" corresponds to the non-idle state. Assume that the intelligent door lock is in an idle state (each task is allocated with only 1ms time slice, and the time for the control system of the intelligent door lock to execute a large cycle is only 5 ms). The user unlocks the lock in a password mode. The 1ms timer judges that the screen control task and the voice broadcast task need to be executed, other tasks do not need to be executed, the time slices of the screen control task and the voice broadcast task are modified into 2ms and 3ms respectively, and the time slices of the other tasks are unchanged (the time for the control system of the intelligent door lock to execute the major cycle is only 8 ms). And the user inputs an unlocking password through the screen terminal according to the voice prompt. The 1ms timed interrupt program judges that the screen control task and the voice broadcast task do not need to be executed, the safety management task needs to be executed, other tasks do not need to be executed, the time slices of the screen control task, the voice broadcast task and the safety management task are respectively modified into 1ms, 1ms and 5ms, and the time slices of the other tasks are unchanged (the time for the control system of the intelligent door lock to execute the major cycle is only 9 ms). The security management task verifies that the password entered by the user is correct (assuming correct). The 1ms timed interrupt program judges that the safety management task does not need to be executed, the motor control task needs to be executed, other tasks do not need to be executed, the time slices of the safety management task and the motor control task are respectively modified into 1ms and 2ms, and the time slices of the other tasks are not changed (the time for the control system of the intelligent door lock to execute the major cycle is only 6 ms). The motor operates and the door lock is opened. The 1ms timed interrupt program judges that the motor control task is not required to be executed, the voice broadcast task and the message reporting task are required to be executed, other tasks are not required to be executed, the time slices of the motor control task, the voice broadcast task and the message reporting task are respectively modified into 1ms, 3ms and 3ms, and the time slices of the other tasks are not changed (the time for the control system of the intelligent door lock to execute the major cycle is only 9 ms). The voice broadcast is that the unlocking is successful, and relevant information is reported to the cloud server. And the 1ms timed interrupt program judges that the voice broadcasting task and the message reporting task do not need to be executed, other tasks do not need to be executed, the time slices of the voice broadcasting task and the message reporting task are respectively modified into 1ms and 1ms, the time slices of the other tasks are not changed (the time for the control system of the intelligent door lock to execute the major cycle is only 5ms), the system resources are released, and each task returns to the original idle state.
Optionally, in the embodiment of the present invention, before determining the state of each task in the at least one task at predetermined time intervals, an initial preset non-idle time slice when the corresponding state is the non-idle state may be allocated to each task in the at least one task. In the foregoing embodiment, in at least one task, when the state is the non-idle state, the preset non-idle time slice allocated to the task may be an initial preset non-idle time slice allocated to the task first.
As shown in fig. 5, taking the intelligent door lock as an example, it is assumed that the intelligent door lock needs to execute at most five tasks, namely, a screen control task, a voice broadcast task, a security management task, a motor control task, and a message report task. When the control system of the intelligent door lock is powered on, the relevant parameters of five tasks of a screen control task, a voice broadcast task, a safety management task, a motor control task and a message reporting task are initialized, corresponding time slices are given (the time slices corresponding to the task screen control task, the voice broadcast task, the safety management task, the motor control task and the message reporting task are respectively 2ms, 3ms, 5ms, 2ms and 3 ms. time slices, after the time slices of each task in a non-idle state are initialized, the state of the task is determined at preset time intervals, the time slices are distributed to the tasks according to the state of the task, for example, when the control system of the intelligent door lock is powered on, each task which is possibly required to be executed is initialized, a preset time slice is distributed to each task, then a 1 millisecond timer is set, the state of each task is regularly inquired every 1 millisecond, when a task is found to need to be executed, the task is executed according to the previous predetermined time slice, and the system resources are released after the task is finished. When the task is found not to be executed, the time slice preset at the beginning of the modification is 1ms, so that the influence on the next task needing to be executed later is reduced to the minimum, and the efficiency of the system for executing multiple tasks is improved.
In addition, in the embodiment of the present invention, it may also be determined whether there is a task that is executed abnormally in at least one task; when the task with abnormal execution exists, the abnormal processing operation corresponding to the task with abnormal execution is controlled to be executed, so that the task with abnormal execution is recovered to be normal. Specifically, after a certain task is executed, a success or failure result is returned, and the returned results of the tasks may be checked, and it may be determined that exception handling is not required according to the results. If the result returned by a task is failure, the corresponding exception handling function of the task can be called to carry out relevant operation. Wherein the state of the task corresponds to a non-idle state when the task requires exception handling. Therefore, the exception processing is judged not to be required according to the execution result returned by the task, and the recovery processing can be carried out after the task is in error.
FIG. 6 is a logic diagram illustrating an execution of an exception handling operation according to another embodiment of the present invention. In this embodiment, taking the intelligent door lock as an example, it is assumed that the intelligent door lock needs to execute at most five tasks, namely a screen control task, a voice broadcast task, a security management task, a motor control task and a message reporting task. How to perform the exception handling operation will be described by taking the motor control failure as an example in conjunction with the distribution time slice shown in fig. 2. The predetermined time interval is 1ms, that is, the state of the task is determined every 1 ms. In addition, in this embodiment, the time slices allocated to the screen control task, the voice broadcast task, the security management task, the motor control task, and the message report task when the state is the non-idle state may be set to be 2ms, 3ms, 5ms, 2ms, and 3 ms. Further, when the task execution is abnormal, a non-idle state is assumed.
And the user unlocks, and the control system of the intelligent door lock executes a motor control task. The 1ms timer interrupt routine looks up the motor control results (assuming an abnormal state is returned). At this time, the 1ms timed interrupt program considers that the motor control task is abnormally executed, and the time slice to which the motor control task is allocated is still 2 ms. And the control system of the intelligent door lock calls an exception handling function corresponding to the motor control task to carry out processing, such as overcurrent and overvoltage detection of the motor, retry operation of the motor and the like. Meanwhile, the 1ms timed interrupt program judges that the voice broadcast task and the message report task need to be executed, and the states of other tasks are unchanged. The time slices of the voice broadcast task and the message work task are modified to be 3ms and 3 ms. The control system performs related abnormity detection on the motor control, such as overcurrent and overvoltage detection, tries to control the motor again, broadcasts voice prompt of unlocking failure and reports information of unlocking abnormity to the cloud server. And then, the 1ms timed interrupt program judges that the motor control task, the voice broadcast task and the message report task do not need to be executed. The time slices of the motor control task, the voice broadcast task and the message report task are modified to be 1ms, and system resources are released.

And allocating time slices for the tasks according to the states of the tasks, wherein the time slices allocated when the tasks are in the idle state are smaller than the time slices allocated when the tasks are in the non-idle state, so that the occupation of system resources is reduced, the waste of the system resources of the processor is reduced, the execution efficiency of the tasks is improved, and better experience is brought to users compared with the case that the tasks are allocated to the time slices when the tasks are in the non-idle state no matter what states the tasks are in.
