Control System'S Integration Of The Ceramic Tile Production Line Based On Network Technology

With the development of such technology as the computer, network, communication, etc., the sharing information has not merely brought enormous convenience to people's life, and caused the deep change of the structure of the automated system in the field of industrial control. In this paper, aimed at the shortage of ceramic tiles product line's control system and the technics flow character of the product line, the way applying network's control to ceramic tiles product line control's system was brought forward. It could complete function of amending, displaying, watching, alarming parameters and control& manage in workshop control room in accordance with the modern development of manufacture workshop. Thus, two facets'work has been done in my paper: In the aspect of system building: according to the principle of "dispersive control and centralized management", the means of three layer network's structure was adopted, namely field equipment layer, network monitoring layer and management layer. The field equipment layer adopts control technology of the field bus ( profibus -DP) to finish such operation as data gathering , communication and real-time control, etc.; The network monitoring layer adopts industry Ethernet technology (SIMATIC NET) to finish great data communication and collection of quantity; The management layer adopts the technology of general Ethernet with TCP/IP protocol to transmit data in a high speed. Finally, such data as reporting to the alarm, trouble, etc. was transmitted to the enterprise headquarters through Internet technology. In the aspect of the software and hardware design: The hardware adopts such hardware products as S7-200/S7-300/S7-400 PLC, communication processor, transducer of Siemens Company ,etc.. According to the system building method, these independent intellectual equipments were made become an organic network. The software uses programming configuration software as tool such as STEP7 V5.1, WinCC V6.0 and IFIX 3.5, etc.. Ceramic tile production line operation and control interface were designed and developed. The results showed that various kinds of operation parameters of this system were showed on CRT, and ceramic tile of production equipment control, monitor, data pigeonhole, history of data printing with trend showing , reporting to the alarm and functioning of printing, etc., were realized and these data was managed through Internet. Using the network control system, the after service quality and the repute of enterprises were improved obviously, and the resources of the whole factory were optimized.
