利用卡诺图解决单对象多地控制问题

针对目前尚没有针对单对象多地控制问题的理论研究,论述了利用卡诺图解决此类问题的方法。在卡诺图中,变量以格雷码的方式排列时,几何位置相邻的最小项在逻辑上具有相邻性,利用这种特点可使单对象多地控制问题中复杂的控制设计过程变得简单易行。以走廊灯多开关控制问题为例,探讨了利用卡诺图解决此类问题的方法,最后用梯形图实现程序的编写。

Karnaugh Map for Single Object Controlled in Many Places

Considering the lack of theoretical study on the single object controlled in many places,employing Karnaugh map for it was discussed.In Karnaugh map,while variables are ranged in Gray code,the minimum term adjacent to others in geometric position also has logical neighboring feature,this makes complicated control design easy for single project.Taking the switch control of corridor lights for example,employing Karnaugh map for similar cases were discussed and using ladder diagram in programming was achieved.
