Petri-Net-based Research On Communication Schema Of Supervisory And Control System

As a standard international message specification for the exchange of real-time data and monitoring information, manufacturing message specification has been widely researched and used. Being the graphical and mathematical modeling tool, Petri net has been applied in the modeling, analysis and imitation of systems, but the conversion from Petri net model to its programming code has rarely been dealt with. The paper uses Petri net to research and model the communication schema for real-time supervisory and control system– manufacturing message specification, studies the conversion rule from Petri net model to programming code, introduces the mapping rule of Petri net basic structure, and then develops the system to implement the conversion using the technology of XML and component, also takes the Petri net models built for manufacturing message specification as examples to validate it.
