摘　　要：为简单化串联型顺序控制电路的结构,提出了一种以CMOS-CC4015移位寄存器为核心的串联型步进控制器的设计思路。该控制器用移位寄存器中各位的状态描述装备的工作步,用现场提供的控制信号(转移条件)作为移位寄存器的移位触发信号,在输入/输出电路的共同作用下实现顺序移位控制。实际应用表明,该控制器具有性能稳定、工作可靠、能耗小、连接简单、免编程等特点。在单机自动化设备的控制中,是一种值得推广应用的低成本控制器。In order to simplify the structure of cascade-type sequential control circuit,this paper puts forward a design thinking of cascade-type step controller with CMOS-CC4015 shift memory as the core. The controller describes the work step of equipment by the state of each digit in the shifting register,uses the control signal（ shift conditions） provided in site as the shift trigger signal of the shifting register,so as to realize the sequential shifting control under the joint action of input / output circuit. The practical application shows that the controller has the following merits： stable and reliable performance,low energy consumption,simple connection,free from programming,etc. In the control of stand-alone automation equipment,it is a low-cost controller,which is worth spreading.
