Abstract: Aiming at improving low informatization level and realise realtime monitoring during the production of allsteel radial tire, the paper intensively studies process features, requirment of system controlling, PLC controlling technology and OPC technology of allsteel radial tire. Based on OLE for process control(OPC) technology, a monitoring system of allsteel radial tire producting procedure was designed to realize the fuctional combination of data collection, data processing, user's interface display, historical data query, incidents alarming, realtime monitoring through technolgy of fieldbus, industrial Ethernet, data base, computer communication and so on. Taking the three compound extrusion production line of allsteel radial tire surface as an example, system's design and realization was detailedly introduced and the experimental platform was built to measure the timeliness and reliability of OPC technology, Ethernet communication and data transmission. The results indicate that the system effectively realtime monitors tire producting procedure, which provides reliable productingly related data for enterprise's desitionmaking managers.
