基于LabVIEW的多种通讯方式数采系统

Data Acquisition System of Various Communication Methods Based on LabVIEW

在数据采集过程中,采集系统的稳定、高速和远距离可控制等性能是非常重要的。针对该多功能性的要求,对以Lab VIEW为软件开发平台的数据采集系统进行了研究。通过以太网和无线两种通讯方式完成了上位机与多路采集系统的数据传输和对采集系统的远程控制,并且系统能够对数据进行预览、存储、回放、预处理等操作。系统还具有自检、复位、存储体擦除等功能。实际应用证明系统可以准确的完成各项功能。

In data acquisition,the performance of data collection systems like stability,speed quickly and control even from long recieving distance is very important. Aiming at these requirements,a research is made on a data acquisition and control system based on a software development platform called Lab VIEW. Through,two kinds of communication methods,Ethernet and wireless,complete the PC and multi-channel data acquisition system of transmission and the remote control of the acquisition system. Furthermore,data preview,storage,playback and preprocessing can be completed in the system. In addition,the functions of self-inspecting,resetting and memory erasing are realized. Practical application proves that each of the operations above can be accomplished in the system.
