摘　　要：本文介绍了一种基于LabVIEW软件平台的单片机多路数据采集系统的设计原理和过程。本设计选用ATmega 128单片机组成的系统作为前端数据采集系统进行多路数据采集，通过RS-485串口通信将数据传输至上位机；利用LabVIEw强大的数据处理和显示功能对采集的数据进行实时处理、分析、显示和存储。This paper introduces the design principle and procedure of a multi-channel data acquisition system with a singlechip microcomputer （SCM）based on LabVIEW. The system consists of a ATmega 128 SCM, it has been chosen as the front-end data acquisition system to achieve the multi-channel data acquisition, and transmits the data to the host computer through RS-485 serial communication. The acquired data is real-timely processed, analyzed, displayed and stored by using powerful functions of data processing and displaying of LabVIEW.
