| 摘 要： | 建立了具有反馈型和非反馈型任务的物联网硬实时控制系统——混合控制任务系统(hybrid controlling task system,HCTS)的任务模型,以全面准确地描述系统中不同任务的结构、交互模式和运行特征,并提出了一种新的响应时间分析方法,用于验证系统是否满足实时性要求.实验结果表明,HCTS中的任务具有较小的平均最差情况下的响应时间,但是在反馈次数较多的情况下对任务的实时性具有不利影响,从而为HCTS的优化提供了支持.

| Abstract: | This paper builds a new task model for hard real-time Internet of Things systems with feedback tasks and non-feedback tasks and presents a new response time analysis method.This task model describes the characteristics of tasks in detail,such as their structures,interaction modes and running manner.The new schedulability analysis method can verify whether real-time requirements are met.Experimental results show the tasks in HCTS have lower average worst-case response time.However,it has some negative influence on the schedulability of tasks in the case of more feedback loops,which provides support for the optimization of HCTS. |
