作者认为:目前通常的控制方法是单端控制。本文提出“双(多)端控制”的概念和一些性质。两种控制方式的区别在于:用一个布尔方程表达的线路,是单端控制;用2个以上的布尔方程并按给定的逻辑结构联立表达的线路,称为“双(多)端控制“。采用这种新的控制方式,可简化结构,扩大控制功能。继电器采用“双端控制”作为特例,证明可构成功能可变的逻辑控制系统。按这种方式亦可建立新型的顺序控制器。这种顺控器已形成系列(DKJB系列)并批量生产。目前已在相当数量的自动化设备中得到应用。双端控制也适用于数字控制技术,亦可使结构简化、运算级数减少。
The author thinks: At present, the common control method is single-ended control. This paper proposes the concept and some properties of “double (multi) control”. The difference between the two control methods is that the line represented by a Boolean equation is a single-ended control; a line expressed by two or more Boolean equations and jointly expressed by a given logical structure is called a “double (multi-terminal) control ”. Adopt this new control method, can simplify the structure, expand the control function. The use of “double-ended control” as a special case of relays proves to be a functionally variable logic control system. In this way, a new type of sequence controller can also be created. This sequencer has been formed series (DKJB series) and mass production. It has been used in a considerable amount of automation equipment. Double-ended control also applies to digital control technology, but also to simplify the structure, reducing the number of operations.
