摘要
提出了一种继电器控制逻辑设计的新方法。通常继电器控制的对象比较简单,人们可以凭经验或试凑法方便地得到控制电路,因而长期以来都没有一个系统规范的关于继电器控制的设计理论。本文把数字逻辑设计原理应用于继电器控制电路的设计,依据对控制对象的控制要求,求出相应控制函数。根据控制函数,画出控制电路。并通过设计实例详细阐述了设计步骤和方法。正如实例所展示的那样,应用本文提出的设计方法可有效地简化设计过程。
This paper proposes a new approach to the design of relay logic control circuits. Because the object controlled by relays is usually simple and unitary, people can easily get the layout of the relay circuit with experience or trying out. Hence, there is not a systematic designing theory of relay logic circuit for a long time. This paper gives the method of designing a relay logic circuit based on the theory of digital circuit. Firstly, according to the demands to the object, the function is derived; then the circuit could be got; finally, there are practical instances added to explain the designing procedure and method. Just as the examples show, the method here can effectively simplify the designing course.
