Recombinant Fms Production System Experiments Environmental Design And Implementation

"The design and implementation of experiment platform for reconfigurable flexible manufacturing system(FMS) " integrates pneumatic technology with programmable logic control (PLC), sensor, computer bus, networked communication etc., which can reconfigure the production system according to customers' requirements in order to solve the contradiction between diverse customers' requirements and batch production. It is characterized by short product development cycle, low development cost, improved product quality, convenient maintenance and product update. The experiment platform can train professional skills for the students and engineers before working through simulating the work conditions of factual production system so as to shorten the gaps between theory and practice and improve the comprehensive skills allaround. Also it provides practical training equipments for training applicable skilled talent and is of application value.This paper is based on the requirement of Nanjing Kangni Science & Technology Co. Ltd and makes some research on the relevant technology of the design and implementation of experiment platform for reconfigurable flexible manufacturing system (FMS). On the basis of former researcher domestically and abroad about reconfigurable production system technologies, the experiment platform for reconfigurable flexible manufacturing system (KNT-FMS) is designed and implemented according to customers' requirements, mainly including unit function design, production state recognition and monitoring system design and manufacturing execution system design. The system can recognize the production states and reflect the factual operation of the production system, whose functional unit can operate separately and execute specific production tasks combined with other units. In our research, functional units are designed by bilaminar hierarchical structure. S 7-300 and PC including CP5611 are selected as unit layer, which communicate with each other by DP to recognize and monitor the production status and realize the coordinated operation of the whole system. S7-200 is selectd as facility unit to control the operation unit for specific tasks. PROFIBUS-DP is used to construct the networked communication between unit layer and facility unit. Then Wincc software is utilized to develop variable modular bases and recognize the production status for the design of status recognition and monitoring system of KNT-FMS. Thirdly, the manufacturing execution system of KNT-FMS is developed using Visual Basic6.0 including user management, inventory management, production plan, process monitor, quality management, facility management and statistic analysis, to realize the issue, scheduling and monitoring of production plan.Finally, future research is presented in this dissertation. The results of our research provide valuable design reference for reconfigurable flexible manufacturing system.
