The Design And Development Of IEC61499 Function Block Compiler Analysis Software Based On XML Language

IEC61499 is new standard system and distributed industrial process measurement and control,synchronization of its function blocks of communication and control abstraction,data transmission and program execution,independent on specific hardware implementation characteristics has great advantages,these advantages conforms to the trend of modern industry control system,comply with the arrival of industrial 4.0.Function block is a kind of abstraction mechanisms,it ins ide the package control algorithm,the system designer if you want to simulation system,don't need to start from scratch to design,only need to select a specific function block,change the application or re configuration,change the control sequence of events can be,so it will be divided into distributed control system design is greatly simplified,in accordance with the standard IEC61499 function block between the events and data input and output interconnections,the structural integrity of the control system.In order to make the function block easy to save and transplant,IEC61499 standard uses extensible markup language XML to define the system,equipment,resources,and functional blocks.Extensible markup language XML is a simple and flexible text format extensible markup language XML,originated from SGML,is a subset of SGML,is SGML a simplified version is suitable for o n the web or a variety of other data sources for data exchange.This topic in the existing based on the IEC61499 standard control system simulation platform design developed the platform of XML files to compile functional analysis,the XML language is used to describe the function block file or logic diagram can through the function in the simulation platform to generate the corresponding function block or logic diagram,and add the dynamically generated XML file function configuration personnel in logic diagram configuration dynamically generated the corresponding XML format to a logic diagram.Through this topic in has been developed on the platform of control system simulation examples to verify the above functions,and applied to the actual,realized base d on XML language of IEC 61499 function block compiler parsing function,convenient operation and human-computer interface friendly.At the end of the paper,the work of the whole project is summarized,and a new prospect for the future is put forward.
