Modeling of Inter-modular Interaction Based on the CANopen Protocol in Vibration Monitoring Systems

摘要

This paper concerns the modeling of communication processes in modular information-measuring and control systems applying the CANopen protocol.Brief information about the format of CAN interface messages is represented and the method for estimating the messages delivery time is proposed and justified.The basic transmission mechanisms for data used by the CANopen protocol are described,and the principles of constructing a program-logic model that allows analysing the processes of inter-modular interaction based on this protocol are formulated.Implementation of the model for a turbine generator vibration monitoring system is exemplified and simulation results are presented.
