基于MSComm和队列技术的LabVIEW数据采集系统设计

针对传统LabVIEW数据采集系统中串行通信实时性不高和程序运行效率有待提高的现状，提出了一种基于MSComm和队列技术的LabVIEW数据采集系统设计方案。该方案以DSP作为下位机控制核心，实现了模拟前端的数据采集，采用PC机作为上位机，基于LabVIEW 2012开发环境，设计了上位机应用软件，实现了模拟前端采样数据的处理、存储、显示及统计分析等工作。实践结果表明，该设计方案具有运行稳定可靠，硬件接口简单、易用，软件编程简单，易于维护和扩展等优点。

Design of data gathering system of LabVIEW based on MSComm and queue

In the traditional data acquisition system of LabVIEW, the real time performance of serial communication is not high and the efficiency of program run is to be improved. Aimed at the above mentioned present situation, one scheme of data acquisition system design of LabVIEW, which is based on the technology of MSComm and queue, is proposed. Wherein, DSP is the control core of slave computer to realize the data acquisition of analog front end and PC is a master computer. On the base of LabVIEW 2012, the application software of master computer is developed. Processing, storage, display and statistical analysis of sampled data of analog front end could be achieved. The testing results show that this design scheme is with the advantages of stable and reliable operation, simple and easy use hardware interface, simple software program, easy maintenance and extension.
