基于单片机的遥控步进电机控制的设计

摘要

采用STC89C52设计的步进电机单片机最小系统,在手动和自动控制模式的基础上,兼顾了遥控操作模式.系统主要由手动输入电路、单片机控制器、电机驱动电路、显示电路、红外接收与发送电路、时钟电路、A/D转换电路以及步进电机等部分组成.不仅实现了步进电机的手动、自动及遥控方式下的正反转,还可以实现定时时钟控制以及LCD状态显示等功能.系统设计安全可靠且便于实现,程序设计简单易懂.%The article introduces the design of single-chip microcomputer smallest system of step motor by using the SCT89C52. It cosiders remote control operation mode in manual and automatic control mode foundation. The system is composed of the manual input and single-chip microcomputer controller, stepping motor drive, display circuit, infrared receive, clock circuit, A/D circuit and stepping motor components.Not only the motor is realized positive rotation and negative rotation by the manual, automatic and remote control, but also is realized the clock control, as well as LCD status demonstration function. The system is designed with safe reliable and can be realized easily, the programming simply easy to understand.
