摘要
针对金相切割机的特点,设计一种基于ARM7的切割机控制系统。主控芯片采用S3C44B0X,步进电机驱动芯片采用A3977SED,给出了主控芯片与外围元器件之间的电路设计方法,A3977SED驱动板的典型应用电路,以及系统的软件设计。采用ARM7控制切割机三轴运动、主轴电机起停、LCD显示,相对于单片机控制系统具有处理速度快、可扩展能力强等优点,相对于PLC控制系统具有成本低、针对性强等优点。实践证明该切割机控制系统性能稳定,工作可靠。
An ARMT-based cutting machine control system was designed for the characters of grinding wheel cutting machines. The paper introduces the basic parameters and characters of S3C44BOX master-chip and A3977SED stepper motor driver chip, and describes the circuit design methods among the external components such as master chip, speed control knobs,control buttons, limit switches, encoders, LCD, driver board, transducer, and expounds typical application circuit of A3977. Compared with MCU control system, it has high scalability and fast processing speed using ARM7 to control cutting machine＇s three-axis movement, spindle motor start and stop, LCD display. Compared with PLC control system,it has low cost and strong pertinence. Practice has proved that the performance of the cutting machine control system is stable, and its working is reliable.
