The Research On The Remote Control Technology In The Industry Production

With the developing of controlling technology and computer technology, especially the widely use of Internet /Intranet technology ,It is possible to remote control the status of industry field. Realizing the information integration from which industry field controlling layer to information layer, and establish the excellent data collection system. Remote control is the key to the enterprise colligate automation construction . Therefore, Remote control system realized production automatization and management network,improving the production efficiency and profit, strengthen the enterprise rivalrousness. It is more and more attention-getting and receiving much recognition by the scholars and technicians.The letterpress expatiates the concept ,developed course ,study status,direction and sorts in exordium; discussed the data communication ,linking mode in remote control network; providing some influential fieldbus, analyzed the system configuration of the fieldbus and function; designed the remote control system based on web technology,giving the work constitution and model, demanding analyse,supplying the SSL secure transmission; introduced the designing of the OPCDA server,including the configuration of the OPC, soft mainboard function, applied example,server enrollment and testing and so on.In the remote control system,OPC is no longer limited in the bottom of the industry field,it has extending to the controlling layer and management layer.In different control system,OPC server and OPC client program could work in the same machine or in different machines.We can not only supply field aboriginal data to the HMI/SCADA applying program, group disposal program, history database but also linking the applying procedure and physical equipment .OPC which is could be used in many systems is the soft interface standard .At last introduced the data collection realization based on internet.At the end of this paper it gives the summary and prospect.
