【摘要】 实时监控系统中各种状态数据和控制信息的传输要求高可靠性和强实时性,制造报文规范(MMS)由于其独立性和互操作性,被电力系统通信机制用作底层协议基础并得到了广泛的研究。Petri网由于能够描述系统动态并发行为并能通过建立数学模型来管理系统行为而被用于MMS的建模和分析。目前,基于Petri的MMS的研究仅限于MMS的建模、分析和验证,缺少从Petri网到代码的自动转换。本文将利用面向对象方法建立Petri网工具,通过图形用户接口实现MMS的Petri网建模和分析,并在此基础上通过映射规则和组件技术实现代码的自动转换。更多还原

【Abstract】 In real-time supervisory and control system,transfers of state data and control information requires high reliability and strong real-time.Because of the independence and interoperability,Manufacturing Message Specification(MMS) has been used as the base protocol for power system communication schema and been widely researched.Petri net as a tool being able to describe dynamic and concurrent activities and manage system by setting up mathematical models has been used for modeling and analysis of MMS.At present,research of MMS based on Petri net only limits to its modeling,analysis and verification,there is a lack of converting from Petri net model to code.The paper will design a Petri net tool using object-oriented methods,it will realize the modeling and analysis of MMS by graphical user interface,and then implement the conversion using mapping rules and component technique.更多还原
