PLC Control And Configuration At Coal Washing Workshop Of Coal Washing And Selecting Plant

Our study subject is the plant of coal washing and selecting in chengzhuang coal mine, who washes and selects coal that belonging power coal of coal mine for about 4 million tons in a year. There are four workshops: origin coal workshop, washing coal workshop, washing smash coal workshop and checking repairing workshop. The whole control system of the plant is composed of three parts (origin coal workshop, coal washing workshop, smash coal washing workshop).Now every control system is in their control room, so the factory transfer workers and the factory leaders could not know the current case in time. Advent ing troubles, they get the information of the failure sets only by virtue of ring. At times, it' s inconvenient to focusing govern and dispatch. Now, for the fact that the census of a lot of data is worked out by hand, there are many lapses on dada, and there are also many problems on the reference and on file of data. For the relative independence of the whole plant control systems and the absence of a produce committing system, there is very much difficult in directing produce and monitoring the sets' running condition. Enhanceing produce committing system, there are many new coal washing and selecting devices by added. Because quite a few control systems are reformed in recent years and the designing thread is changed old, and they are far away from the need of safe produce, the whole control system must be reformed. Nothing but so, the produce will go on safety and efficiently. At the same time, what we will do will pave the way for the formation of establishment auto system.At present, the PLC control , the up computer configuration and communication are very enthusiastic technology. With the develop of PLC technology, on account of the high reliability, high property and price rate, broad industrial scene orientately and convenient technical expansions, PLC is more and more widely used in the control of industria automation.At the background of all above, the article is beginning from the basic frame of PLC, compareing the property of PLC, which is usually used at home. Studying some usual design manners and a few basic means improving reliable in the PLC control system. Analyse the ways of hardware and software designing in PLC control system. In main raising control system of original coal workshop, PLC function models communicate with machine tail branch station in coal well using dual wringing strings by GENIUS net. And they also communicate with every electricity division chamber by DEVICE net. At coal washing workshop, the control system take use of the PLC of GE 9030 , and connect all five branch stations with DEVICE net. We put forward concrete answers of some scene practical question. Using PLC control technology, we design the whole auto control system. The up computer configuration software which belonging Beijing KingView cor is used in PLC monitoring control system.
