随着计算机的迅速发展,控制系统也发生了很大的变化,逐渐从离线转为在线化,由单机控制发展到计算机分级控制。分级控制中最基本的要求就是计算机之间的数据通讯问题。以氧气顶吹转炉炼钢为例。此种炼钢技术在生产中已充分显示其重要作用。由于氧气顶吹转炉吹炼周期很短,必须准确地判断吹炼终点,提高终点的命中率,炉龄和质量。由自由炼钢转向科学炼钢,必须采用计算机进行控制和管理。计算机可根据静态/动态模型,按附加料模型,枪位模型来控制附加料的加人数量和时间,控制变枪和枪位并对检测到的过程信息进行修正,以达到终点目标有较高的命中率。在这个系统中,牵涉到在线检测和收集数据及对
With the rapid development of the computer, the control system has also undergone great changes, gradually from offline to online, from stand-alone control to computer grading control. The most basic requirement in grading control is the data communication problem between computers. Take oxygen top converter steelmaking as an example. Such steelmaking technology has fully demonstrated its important role in production. As the oxygen blowing furnace blowing cycle is very short, you must accurately determine the end of blowing, improve the hits, furnace age and quality. Turn from free steelmaking to scientific steelmaking, you must use a computer for control and management. Computer according to the static / dynamic model, according to the additional material model, the gun position model to control the additional material to join the number and time control of the gun and gun position and the detected process information to be amended to achieve a higher end goal Hit rate. In this system, it involves the on-line detection and collection of data and pairs
