The Research On Remote Control Technology Of Process Control System Based On Ethernet

With the popularization of the network technology of the computer, the fundamental change has taken place in the worldwide industrial structure. It promotes the development of global informationization. In the field of industrial control, control network technology has already become the focus of automatic technical research.The traditional control scheme has been already unable to meet the demand for modernized industrial production, and has hindered the speed of development greatly. So, with the inter combination of Internet technology and control technology, distributed control network that based on internet have gained of more and more extensive application in industrial process control system, which can be as a superior mode of integration of scene micro-control and enterprise macroscopical decisions.This paper took kiln monitoring system of ceramic tunnel as the backgroud, discussed the remote monitoring system which built up on the basis of industry's Ethernet controls. It has utilized the data acquistion technology, network technology, communication technology and object-oriented programming technology synthetically, fully used Browser/Server mode and Client/Server mode one's own advantages, and adopted the hiberarchy and module design means. Meanwhile, the monitoring system used the advantage of Ethernet and OPC technology, overcame the inferior position of the existing fieldbus, carried out the real-time data of the control network.The key point of the thesis was put in the communication of the monitoring system. After analysed and compared the B/S and C/S, the paper utilized the two each one's own advantages synthetically, and set up the monitoring system of mixing the mode, utilized WinSocket technology and object-oriented programming technology to achieve server systematic communication between server and customer end, and show the control information and report to the police and user person who manage function module. This monitoring system has offered a kind of new thinking in remote control system. After some time, remote controlling technology will be used extensively in industry and even in civilly.
