基于labview的三轴位移系统的设计
摘要:本设计以SCT89C52单片机作为下位机，同时也是控制核心器件。利用labview作为上位机开发软件，对单片机内的脉冲信号进行控制。该虚拟信号发生器能实现1MHz频率、占空比可调的方波输出。该设计的核心部分为单片机的时间计数器和labview的程序设计，以及labview与单片机的通讯。Labview与单片机通过usb线转RS232的方式进行通讯，该转换有一块芯片实现，此处不多赘述。通过上位机旋钮控制占空比的比值可在30到80之间变化。该三轴位移系统主要包括labview上位机，SCT89C52单片机、方波脉冲信号、程序下载模块、步进电机以及三轴的铝制框架。该三轴位移系统有性能稳定，价格低廉以及结构稳定的优点。

Design of triaxial displacement system based on labview
ABSTRACT: This design takes the SCT89C52 single-chip computer as the lower computer, also is the control core device. The pulse signal in single chip microcomputer is controlled by using labview as the development software of upper computer. Thevirtual signal generator can realize the squarewave outputwith 1MHz frequency and duty cycle adjustable. The core part of this design is the time counter of single chip computer and the program design of labview, and the communication between labview and single chip computer. LabVIEW communicateswith single chip through usb line to RS232. The conversion is realized by a chip. The ratio of duty cycle controlled by the upper knobvaries from 0 to 100. The three-axis displacement system mainly includes labview upper computer SCT89C52 single chip microcomputer, squarewave pulse signal, clock circuit, and program download module. The three-axis displacement system has the advantages of stable performance, low price and stable structure.
KEYWORDS: Labview-STC89C52 single chip microcomputer; timer; three-axis displacement system.
