Computer Remote Control System In The Process Of Chemical Technology

The problem now facing the chemical industry is that the control model does not adapt the new information progress. The paper researched and established a model of Computer Remote Control System that can be used in Process of Chemical Technology and resolve the problem.The computer-assisted automation control systems were being used widely and they experienced about five development stages: DDC, SCC, DCS, FCS and CIMS. But with the progress of chemical industry and the global information the industry required more quick and precise technology to be managed and controlled. The improvement of remote communication technology make that possible.The Computer Remote Control System in Process of Chemical Technology consists of three parts. The first part is control center that assembles the distributed data and sends the operation commands. The second is the field units that are used to collect and store device data and send them up to control center. And the field units may be a PLC, single board computer, FCS and so on. The third is a remote digital network for transporting the digital data between the control center and field units.
