Research On PROFIBUS About Automatic Blend Control System

The blend technology is one of the most important technology in Chongqing iron&steel coking mill , and that such runs the state directly affects that mill coking's quality together with the yield , and then effect wholly corporation manufacture immediate, as a result gurranteing that such is steadyd regularly ruing haves the action that holds the balance to Chongqing iron&steelChongqing iron&steel corporation coking mill in the interest of gurrantee the initial failure-free operation of that workman has been underway reforming to the get materials ready in blend control system attempt time and again , as speedily developing of the bus and communication and information technology , PROFIBUS's bus realization of resolution by means of adopts is to the get materials ready in blend disc automatic control , and unites the electric network at the moment moreover and the communication technique development , implementation video frequency supervision and the telemangement is establish the automatic get materials ready in the blend control system . By means of systematically adopts PROFIBUS's bus to dominate , implement adoping of video frequency and telemangement , and lift the get materials ready in the blend system operation dependability , raise amount coordinating with the coal quality , and guarrantees that the coke oven gives birth to the necessaries in the way of the coal to the get materials ready in the blend. The person who researcies sense resting with raise is distributed coal contrasts , and guarrantees to coordinate the quality of coal , and in the interest of regular manufacture the suppling guarantee of coke oven , lift coking's quality together with yield , and guarrantees that the corporation gives birth to regularly , and lift that workman's sequence is dominateeed together with the administration level , and attaches most importance to that the orientation reformed probing in the steel coking mill automation , and have the greatter economic results .The dissertation is summarized the technique to the field bus , and analysing the some kinds of field bus technique at the moment , and analysed PROFIBUS's bus technique theory , uniting the actual situation of Chongqing iron&steel coking mill , get materials ready in the blend control system every the section technique scheme was detailedly elaborateed by the dissertation , and adjusting the installation mould chooseing , the field installation is debugged and so on configuration work to the system . Steading and signal transfer that the substance that relates to possess in the get...
