Control System Simulation Platform Development And Application Research Based On IEC61499 Standard

IEC61499 is a new standard for distributed industrial process measurement and control system. The data transmission,synchronous program implementation,the characteristics of communication and abstract control between the function blocks is independent of specific hardware implementation methods.They have obvious advantages, which are consistent with the development trend of industrial control system and conform to the arrival of industrial 4.0. Developing a system of coordinated, flexible configuration and convenient control function block operation platform makes the engineers who are not good at program development can easily understand and apply it.Function block is an abstract mechanism.Its control algorithm is encapsulated in the interior.The system designerswant to do system simulation, with no need to redesign the each link from the beginning.They only need to select a specific function block, change application or reconfiguration and change the control sequence of events.Therefore, distributed control system design is greatly simplified. The input and output of the events and data interconnection between function blocks in accordance with the IEC61499 standard complete control system.This paper studies the system structure based on the IEC61499 standard.In the study the type of model and the definition of function blocks and control function block development platform are completed.It also includethe creation of function block corresponding double click on the tree directory; function block’s selected and deleted; function block’s drag; dynamic connection between function blocks; parameter setting of function block instances; operation state’s dynamic effect display of function block; and based on the standards developed common block in the control system, including the input and output function block, signal function block, control arithmetic function block and so on, the design of their event trigger mechanism, data type and function realization algorithm.Through the example research in the developed simulation platform of control system, this paper achieves that data transfer mechanism between different functional blocks, and turn the dynamic simulation of the control system out.The Platform is applied in realityand finally realizes the simulation results, which is easy to operate and friendly man-machine interface. At the end, the whole research work is summarized and puts forward a new prospect for the future.
