摘要
本文介绍了单片机控制的电动机Y-△启动电路设计,该设计实现的功能为:1.控制器为单片机,电动机为三相异步电动机;2.启动时间为3秒;3.由按键设置电动机Y-△运行、停止等功能,为智能控制和精确控制电动机启动提供了有效的解决方案,是一个典型的弱电控制强电的设计。本文对系统各模块进行了详细设计,重点论述了系统各模块的硬件电路设计,对软件设计和软硬件综合调试进行了全面地分析与说明。本设计以单片机STC89C52RC作为主控制器,利用STC89C52RC内部的定时器实现定时启动时间功能,通过控制继电器去控制电动机运行,实现弱电控制强电,以发光二极管作为指示,以两位级联共阴数码管作为显示器显示延时剩余时间,用独立式键盘对电动机启动时间、电运机启动、停止进行控制,具有友好的人机界面。经过设计和调试,本设计的实现了设计任务的各项指标。
The paper introduces the motor based on single-chip microcomputer control design of the train start Y - the princess, the design and implementation of function for： I. the controller for microcomputer, motor for three-phase asynchronous motor, 2.to 3 seconds, start-up time, 3. by button motor train operation, stop Y - functions, for intelligent control and precise eontrnl motor startup provides an effective solution, is a typical low ＆high voltage eontn^l design. This paper makes a detailed system module design, this paper focuses on the system module, the hardware eiix＇uit design of hardware and software design of integrated debugging conducted a comprehensive analysis and explanation. This design is made by STC89C52RC mieroe^nnpuler, using the STf289C52RC internal controller timer funetion, realization time start-up time through control relay to control motor rnnning, low ＆high wtage control, with light emitting diode as the instruction, with two level which Yin digital display as the remaining time delay, indepen- dent ~f mttlor start-up time, keyboard electrical transport machine start and stop, with friendly human-machine interface. Through the design and de- bug, the design of the indexes of the design task.
