一、引言近年来,以大规模集成电路为基础的微型计算机在工业控制各个领域取得了成功的运用。国外对于线材和棒材轧机采用微型机控制系统的研制于1976年开始,至今已有多套轧机顺利投产。这些轧机均采用多台微型机按工艺流程进行分散控制,其优越性在于硬件局部故障不易扩散,提高系统的可靠性,软件具有高度独立和灵活性,改善了整个系统的响应速度及控制功能,系统易于设计和维护,投资少,周期短。随着微型机应用水平的提高,在连续
I. INTRODUCTION In recent years, microcomputers based on large-scale integrated circuits have been successfully used in various fields of industrial control. Foreign countries for wire rod and bar mill using microcomputer control system development started in 1976, so far has been a number of sets of rolling mill successfully put into operation. These mills are using multiple microcomputers according to the process of distributed control, the superiority of the hardware is not easy to spread local problems, improve system reliability, highly independent software and flexibility to improve the overall system response speed and control functions, System easy to design and maintain, less investment, short cycle. As the level of application of microcomputers increases, continuous
