The Research Of Communication Technology Of Distributed Monitoring System Base On Ethernet

Obviously, it's a kind of successful practice to monitor working fields, to get first-hand data from there and make management in higher efficiency for modern industrial enterprises. Industrial monitor system face imperative requirements as cruel competition from market, advanced function and diversified clients. What's more , how toexpress clearly requirements of the client system, modeling of function and information, how to transform from the model to software code smoothly and how to testify model and make system's design much better are real foundation for better distributed monitoring systems.Aiming to above questions, this paper took the project funded by Gansu province as the background, discussed the distributed monitoring system which built up on the basis of industry's Ethernet controls. It has utilized the data acquisition 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 The way of OPC technology and soft gateway technology, overcame the inferior position of the exiting fieldbus, carried out the real-time data of the control network.The key point of the thesis was put in the communication of monitoring system. After analysed and advantages synthetically, and set up the monitoring system of mixing the mode, utilized WinSocket technology and object-oriented programming technology to achieve 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.
