The Design Of Graphite Electrode Production Process Parameters Monitoring Network Based On MCGS And CAN-bus

Because of the high energy consuming and pollution of graphite electrode profession, the scale of carbon productions, which could produce the high power, the super elevation power of graphite electrode products, in the developed country all over the world is shrinking day by day. Meanwhile, along with the rapid development of the new technical progress and the increasing demands of the graphite electrode quantity for many developing countries, the management of each link craft in the graphite electrode productions is very important to the graphite electrode quality. Therefore, the establishment of monitoring networks to the graphite electrode production process is imperative, which will carry on strict managements to each production link.The purpose of the study in this paper is to establish the monitoring network to carry on the online monitor to the graphitized each production link, and provide the essential process parameters for the craft management. The monitoring network establishment may realize each link of the graphite electrode production real-time data browsing, real-time curve analysis, history data analysis as well as history data storage and so on. The labor entertainer may analyze the graphite electrode quality influence factor from these data, then the adjustment strategy, issuing ordersThis paper gives a brief introduction of the graphite electrode production flow, the characters of the field bus, analyzed the advantage making use of the CAN-bus to build the graphite electrode production process parameters monitoring network. Expound the economic value of the graphite electrode production monitoring network. Given the method how to build the monitoring network in particular, and has designed the communication program of the monitoring network on the platform of the configuration software.In the view of the existing graphite electrode production process parameters monitoring network, the reliabilities are bad, which could not realize the equipment with different communication connection to enter the net, the data storage, the analysis and management are not convenient at all, the software configuration cannot directly control the CAN card and the network locates the environment of much disturbance and so on. This paper proposed the methods to realize the CAN network communication on the configuration software platform and uses the switch module on the different communication interface equipments. Also OPC server between configuration software and the CAN card to realize the configuration software operating the CAN card and the software filter, the repeater, the reasonable wiring, isolation module are used. Software and hardware measure is used to enhance the communication reliability of the network. The establishment of the monitoring network has provided a very good platform for management, analysis of data to the craft personnel, and satisfied the request of the system functions.The result of the network actual performance proved the graphite electrode process parameters monitoring network based on the configuration software and CAN-bus proposed by this article is feasible. It has has many virtues: the low construction cost, convenient to implement , simple for software design, easy to grasp, the good reliability. It has provided the reliable safeguard for the product quality enhancement of this company and has had the remarkable economic efficiency and has met the graphite electrode quality craft monitor management needs.
