摘　　要：在采用模型驱动的开发(MDD)方法对复杂实时系统进行建模设计时,单层的建模方法难以完成对控制系统的清晰和完整描述。针对上述问题提出了一种分层递阶机制的实时多层建模方法,该方法使用可扩展输入端口和输出端口对现有元模型技术进行扩展,采用可扩展标记语言(XML)实现端口的描述,利用基于信道的端口消息传递机制完成不同层模型之间通信。实际实时控制系统建模结果表明,与单层模型相比,分层递阶的建模方法能够有效实现模型驱动设计方法在实时领域内对并行多任务和复杂交互行为的描述,从而提高实时领域模型的可读性和可复用性。When the Model Driven Development （MDD） method is used in real-time field, it is difficult to describe the whole control system in a single layer completely and clearly. A real-time multi-layer modeling method based on hierarchy theory was presented in this study. The extensible input port and output port were adopted to equip present recta-model technique in real-time field, then the eXtensible Markup Language （XML） was used to describe the ports and the message transfer mechanism based on channel was applied to realize communication between models in nmtiple layers. The modeling results for real-time control system show that compared with single layer modeling method, the hierarchical modeling method can effectively support the description of parallel interactions between multiple tasks when using model driven development method in real-time field, as a result it enhances the visibility and reusability of real-time complex system models.
