摘要
电气二次图的设计要体现二次设备日趋复杂的逻辑功能。针对实现电气二次图的逻辑功能以及简化、优化逻辑回路结构的问题,提出了将逻辑代数引入电气二次图设计的方法,阐述了利用卡诺图对逻辑表达式进行化简的具体步骤,并通过工程实例呈现了该设计方法对工程设计人员的指导价值及其广阔的应用前景。
It intends to more complicated that design of electrical secondary circuit diagram to incarnate the logi- cal function of secondary circuit devices. To realize logical function of electrical secondary circuit diagram, sim- plifying and optimizing the structure of logic circuit, that logic algebra is brought into electrical secondary dia- gram design is put forward. The simplification steps of Karnaugh in logical expression are expatiated. Through the engineering practice, the design method shows it is guidable to engineering designer and has wide applica- tion prospect.
