Title    Design of optical information collection  and exchange system based on OPC communication                                     

Abstract By deeply analyzing and studying in the process of industrial production, due to excessive production equipment data deposition, so that enterprises in the face of how to collect, store and calculation has a lot of difficult to achieve。 The first in-depth study of the significance of the topic and a combination of domestic and international currently has done the research to carry on the analysis and exploration, and on this basis, and puts forward the solution of OPC Technology of optical signal acquisition and measuring system。

Secondly, in the actual production process with OPC technology and OPC data access is for the reference of the practical research is expounded in this paper, combined with research and analysis of the types,the PLC relay data to the actual production in the PLC data acquisition flow and to demand the goal value。Then, research the key technology of OPC Technology of optical signal acquisition and processing system based on: Research of OPC technology and PLC optical signal data acquisition, the measured data with the OPC communication system for computing technology research based on。

Finally, based on the construction based on OPC Technology of optical signal acquisition interaction system model based on the concept, using LabVIEW software to construct the basic framework of the structure, and development based on OPC technology optical signal acquisition interaction system。
