Abstract: This paper presents a model-based design approach to the constrained scheduling problem of the SCADA based on the producer-consumer model.According to the demand of application in the validity period of data and the estimated computing time of a task,designer calculates the parameters to real-time scheduling and the constraints,and schedulbility can be analyzed.The method can be applied to design the real-time embedded software with time requirements.

摘要: 提出了一种基于模型的实时调度设计方法,利用生产者-消费者模型解决约束条件下的SCADA系统实时调度问题。设计者可根据应用需求中的数据有效期及估算的任务计算时间,通过提出的模型计算出其他实时调度的参数,给出约束条件,并进行可调度分析。提出的方法也可用于设计有确定时间要求的实时嵌入式软件。
