Study on Data Communication Management Methods for Distributed Intelligent Equipments in Manufacturing Systems

摘要

For a comparative study of some data management methods when independent equipments have to communicate with a central server and discontinuities appear in the communication process, a simulation method was designed, software was developed and tests were run for different data recovery methods. Data recovery procedures were placed in different points of the equipment's activities sequence and the complexity of the simulation software was gradually increased till the stage in which multiple equipments were simulated and failures were taken into account for all system components (equipments, server and communication channel). Results were compared both for testing the simulator correctness and for appreciating the methods' effectiveness and future developments are mentioned.
