Data Integration And Software Development Of The OPC-Based Monitoring And Control System Of Robot Welding Product Line

Surrounding with the design of the Monitoring and Control System of Robot Welding Product Line, which is the subtask of the Tenth Five Tackle Key Project of Jiangsu Province 'R&D of Open Network Industrial Robot and the Application Project of Automobile Welding Product Line of Yuejin Motor Combine', this thesis discusses the problems of requirement analysis, data integration and software design of the Network Monitoring and Control System in detail which is based on the Client/Server structure.This thesis introduces the function and characteristic of network computer monitor and control system. And requirement analysis is presented to the monitoring and control system of welding product line which is made up of six COMAU robots in the Body Plant of Nanjing IVECO Motor Company LTD. The system is based on the Client/Server structure, in which the monitoring computer communicates with the partner devices such as PLC of SIMATIC using PROFIBUS protocol, and robots connected with the monitoring server through Ethernet after there are reconstructed with network. This thesis explores the data integration method of the isomer system, and designs the database for data traffic between the monitoring application software and the partner devices. Then the management data integration platform of the product line is constructed, which provides the basis of subsystem communications and data sharing. After that, this thesis analyzes and designs the software of the system in detail. Finally, data traffic technology, OPC, is introduced and application of OPC Server is also discussed in the monitoring and control system.
