 ## Introduction<a name="section11660541593"></a>
 
-In the resource scheduling subsystem, the work scheduler component provides a mechanism for applications to perform tasks that require low real-time performance. When the set conditions are met, it will be put into the executable queue, and the system will delay triggering tasks in the executable queue according to the equipment situation.
+When an application needs to perform tasks that do not require high real-time performance, such as data learning when the device is idle, the work scheduler can be used. When the application setting conditions are met, the mechanism will uniformly decide the scheduling time according to the current state of the system, such as memory, power consumption, heat, etc.

 ## 简介<a name="section11660541593"></a>
 
-在资源调度子系统中，延迟任务调度部件，给应用提供了一个机制，用以执行对实时性要求低的任务。当满足设定条件时，会被放入可执行队列，系统根据设备情况，延迟触发可执行队列内的任务。

 ### 使用说明<a name="section129654513264"></a>
-应用要执行实时性不高的任务的时，可以使用延迟调度任务，该机制在满足应用设定条件的时候，会根据系统当前的状态，如内存、功耗、热等统一决策调度时间。
