| 摘要: |
| 为了提高软件的可维护性和可扩展性，降低规约开发的复杂度，基于统一建模语言(UML)的状态图理论对IEC 60870-5-104规约主站端进行了分析。抽象定义了动作、事件和状态，利用UML状态图分层和并发特性设计了规约逻辑状态图，并使用Qt的自动机框架进行了软件实现。结果表明，设计出的状态图层次结构分明，逻辑关系清晰，各功能模块间相互独立，而且降低了耦合度，编程实现简单明了，体现了这种方法的优越性，对其他复杂通信规约的开发也具有一定的参考价值。 |

| Abstract: |
| In order to improve maintainability and expansibility of software, reduce the complexity of protocol development, based on the statechart theory of Unified Modeling Language (UML), this paper analyzes the master side of IEC 60870-5-104, abstracts and defines actions, events and states; designs the statecharts of protocol logic based on the hierarchy and parallel characteristics and implements the software using Qt state machine framework. The results show that the hierarchy structure of statecharts is distinct, the logic is clear, every function model is independent of each other, and the coupling is reduced; programming implementation using Qt state machine framework is easy, showing it is a good solution. This kind of analysis and implementation method has also good reference value to the development of other complex communication protocol. |
