描述

3HAC14549-3/12A

 在自动化的许多领域,有效性的要求越来越高,因而对自动化系统的容错水平的要求也变得越来越高,尤其在设备停机代价非常大的场合。为了满足这些严格的要求,在DCS系统中通常采用冗余技术,这样才能够满足这些领域所需要的安全性、可靠性和有效性的标准。
    在DCS控制系统中,分布处理单元是系统关键的部分。当前这些分布处理单元的控制器往往是基于86系列CPU建构的,这种架构目前被广泛采用。但是由于86系列分布处理单元的特点,导致现在的控制器处理单元存在很多的缺点,如放热量大等。而且在封闭的环境中,这些问题始终很难解决。随着很多低功耗技术的发展和低功耗控制器的出现,分布处理单元的CPU可以有更多的选择,尤其是低功耗的控制器产生很少的热量,且可以使系统的集成度更高。
    无论是国内还是国外的DCS控制系统之间有多大区别,冗余技术在这些DCS控制系统中都被广泛采用。DCS控制系统中主要采用了网络冗余技术、分布处理单元冗余技术、IO卡件冗余技术、电源冗余技术等。
    1、DCS系统的模型
    DCS控制系统是控制技术、计算机技术、通信技术及图形显示技术相结合的产物,其一般的体系结构见图1。由图1DCS控制系统模型框图可知,DPU指的是分布处理单元。DCS控制系统的体系结构分为3层:过程控制层、监控层和管理层。其中过程控制层是DCS系统控制的基础,其设备的主要功能是控制接口、现场控制单元、检测仪表和执行机构;监控层主要由监控计算机、高级操作站和接口装置构成,主要负责操作监视、系统报警、趋势显示及系统诊断等功能;管理层主要由管理计算机组成,负责整个系统的管理工作。

先介绍几点经验。
1、先通读一遍“系统手册”(不管能不能看懂,先了解个大概,以便学习编程时查找);
2、由位控逻辑入手,逐渐增加定时、计数等条件,把或、与、非关系理顺;
3、进而练习整数运算、实数运算、类型转换;
4、量程转换、PID调节回路的建立及P、I、D参数的理解(最好是有个物理回路验证,比如变频器+电机+测速传感器);
5、循环、顺序、跳转等程序控制(尽量避免跳转,非跳不可时也是跳的越近越好);
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列,GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌,由于PLC的基本框架大同小异,学会一种至于其它的学习起来也就简单了。
