Research On Distributed Control System Of Coal Preparation Plant For Zhongmacun Coalmine

With the development of modern industry, the coal consumption is increasing, while the coal quality requirements have been raised. Bring coal preparation plant production technology is more and more complex, the traditional preparation control system cannot satisfy the control requirements of coal preparation plant, needs to carry on the transformation. Coal preparation plant has complex process, characteristics of the equipment, coupled with modern coal preparation plant control efforts are being made to the network, intelligent direction. In this context, the upper control in coal preparation plant is particularly important.This paper based on programmable controller design as the core under a control system, at the end of the first in the coal separation system process are analyzed and summarized, the second study on the understanding of the sorting equipment, determine its operation principle, hardware design through the various last sensors to measure parameter.Collecting the sorting equipment the working conditions of the power and various parameters and other parameters, direct control machine next a LCD display system parameters and realization of alarm functions, so as to highlight the centralized control way more local control mode, the superiority of coal cleaning technology also achieve the accuracy of the system control and fast speed.
