摘要
介绍基于LabVIEW的数据采集处理系统,它利用AVR单片机进行多路数据采集,然后对采集到的模拟信号进行放大后送入AVR单片机,并将AVR单片机模拟成低速的USB设备实现AVR单片机与上位机的通讯,将AD转换后的数据通过所模拟的USB端口传至PC端,同时在LabVIEW中对采集到的数据进行实时滤波处理、显示及存储等功能。实验结果表明该系统能满足预期的目标和要求,并且在实际应用中可以大大降低成本。
The data acquisition and processing system based on LabVIEW was proposed which AVR microprocessor was used to collect data in multi-channels,and then the magnified analog signal was sent into AVR microprocessor.In order to send the converted data through the simulative USB to PC port,the communication between AVR microprocessor and PC was achieved by AVR USB technique.At the same time,the collected data was filtered,displayed and stored real-time in LabVIEW.The experimental results show that the system can satisfy the desired goal and requirement.It will reduce the cost in the practical application obviously.
