| 摘要: |
| 电力系统于1998年开始推行新的电力系统远动规约标准IEC60870-5-101,为了便于该规约的推广应用,编写较好的应用软件,引入有限状态机FSM(FiniteStateMachine)进行设计,并且基于面向对象技术提出一种高度结构化的有限状态机的实现框架。同时,应用有限状态机理论,抽象出链路层对象的有限状态机模型,并用状态图进行描述。有限状态机实现框架的引入,实现了灵活的复用机制,提高了系统的健壮性和可维护性。通信软件的开发,提供了一种比较便捷通用的开发模式,且现场实际运行良好。 |

| Abstract: |
| The international standard protocol-IEC 60870-5-101 has been applied as the communication protocol in power system since 1998.High-quality application software is required for its popularization.FSM(Finite State Machine) introduced in the design and an object-oriented and modularized FSM implementation framework is presented.Based on FSM theory,the FSM model of link layer object is abstracted and described by a state digram.It realizes the flexible reuse and improves the system robustness and maintainablity.The communication software provides a convenient and universal design pattern and runs well. |
