摘要
以LabVIEW7.1为软件平台,充分利用虚拟仪器技术对微型燃气轮机燃烧室热态实验系统的温度、压力、流量等模拟量参数进行精确测量。能实现实验数据的实时采集、实时分析、数据图形化显示、虚拟监测和实时信号反馈处理,使得测量的重点转向软件的设计。由配备数据采集卡和信号调节模块的普通PC电脑实现数据采集,与传统的测量方法相比有效提高了开发效率和实验测量精度,缩短了实验时间并削减了经费开支。
Based on the LabVIEW virtual instruments measuring techniques, a measuring platform for performance investigations of the micro gas turbine combustion chamber is constructed with which the analog quantifies such as temperature, pressure and flowrate during experiments can be measured precisely. By this measuring platform, real-time acquisition, analysis, graphical display and feedback of the experimental data can be realized, and the measurements will centre on the software development. Data acquisition is realized by a PC equipped with DAQ cards and signal conditioning extension for instruments. The development efficiency and measurement accuracy are improved, and the experimental duration and expense are reduced compared with the conventional measuring techniques.
