Design and Implementation of a Method and Framework for Dynamic Loading of the Function Methods in Cyber-physical Systems Nodes

Abstract

In order to satisfy the need of the function methods of slaver nodes for dynamic load after the nodes in the Cyber-physical Systems (CPS) network been dynamically reconstructed, and provide a unified specification to develop and call the different function method, this paper puts forward a method and framework of dynamic loading of the function methods belong to the CPS nodes. In this method and framework, provide uniform interface specifications, compile the code of the function methods into binary executable files and store it in the storage space of the slave node. During initialize the node, read the binary data to master node, and then load the function methods by parsing it directly and execute by name. Establishing an experiment system to verify the method and framework, the function methods could be loaded successful and it could realize accurate control of slave nodes.
