用于《过程计算机控制》实验课的DDC系统

DDC system applied to experimental course of process computer control

DDC(直接数字控制 )系统是根据《过程计算机控制》课程的内容 ,主要研究生产过程中利用计算机实现自动控制的方法所设计的 ,由微机、接口箱、被控对象以及CAI软件组成 该系统能够生动、形象、全面地引导学习者进行计算机控制系统的设计、调试、实验 经过不断地改进、完善 ,使用效果良好 着重介绍了DDC系统的功能特点。

Based on the course of computer process control,the DDC system has been devised for the means of automatic control in the production process using computer.According to the research subject,combined with present device,the DDC system have been made,which is made up of microcomputer,interface processing unit,controlled object and CAI software.The DDC system can instruct students to learn how to design and debug computer control system,and students can do experiment with it.After continioues improving and perfecting,it is becoming better.The functions,characteristics,constituent parts of the DDC system and the guidance are introdued.
