基于LabVIEW平台的在线监测诊断系统多任务调度策略

The Method of Scheduling Multitasks in the Online Condition Monitoring and Fault Diagnosis System on LabVIEW

任务调度策略,是开发复杂多任务应用程序的关键。基于优先级的设置和执行系统的选择,结合固定时间间隔调度和事件驱动机制,提出了LabVIEW平台两级多任务调度策略:平台级调度策略和用户级调度策略。并以一套在线监测诊断系统为例说明了调度策略的实现过程。

The method of scheduling Multitasks is the key of developing a complex and Multitasking Application.Based on setting priorities and selecting execution systems ,and by means of fixed time waited and event driven,this paper puts forwards a method of two level scheduling multitasks on LabVIEW.One level is decided by LabVIEW and the oth-er is decided by user.As an example,this method is applied to an online condition monitoring and fault diagnosis system.
