卡诺图在继电接触器控制电路触点化简中的应用研究

Application of Karnaugh-map in Simplifying Contacts of Relay-contactor Circuit

传统的继电-接触器控制电路触点化简时,化简原则明确,但缺少具体的化简方法。研究了卡诺图在继电-接触器控制电路触点化简时的具体应用情况,分析了电路的逻辑表达式转换、卡诺图化简及化简后电路的反变换。研究表明,将卡诺图应用于继电-接触器控制电路触点化简,可以降低控制电路设计成本,提高系统的可靠性。

Traditionally,When simplify the contacts in the relay-contactor control circuit design,The principle is clearly,but simplified method is needed.The article studies the Karnaugh-map used in the relay-contactor control circuit design,and examples are given to analyze the circuit logical expression conversion,Karnaugh-Map reduction,the circuit inverse transform.Iiit proposes somethings that need for attention when using Karnaugh-map simplifies the contacts in the relay-contactor control circuit design.
