基于步进电机非线性折射率测控系统设计
Design of a Non-Linear Refraction Rate Measurement and Control System Based on Step-Motor
【摘要】 提出了一个基于步进电机非线性折射率测控系统.整个系统以AT89C51单片机为核心,设计了步进电机驱动电路,光电探测电路和A/D转换电路实现对非线性折射率的测量.用VC++6.0编写了上位机软件,实现单片机与上位机通信,对测量数据的分析、处理以及对整个测控系统的控制.
【Abstract】 A non-linear refraction rate measurement and control system is proposed in this paper,which is based on step-motor.Centering on AT89C51 MCU,the whole system designs step-motor drive circuit,photoelectric detection circuit and A/D changeover circuit,so as to realize non-linear refraction rate measurement.Written in VC++ 6.0,the software aims at MCU and PC communication,data analysis and system control.
