摘 要
本监控系统主要采用虚拟仪器的思想,结合计算机的结构特点,提出了一种以计算机为平台,基于LabVIEW的监控系统,它是以采集目标源信息,采集输入到信号分析模块经过判断来确定系统是否稳定的一种监控手段。在本监控系统主要流程是数据采集输入、输出、信号分析、判断、 结果显示。在本程序中将采集到的数据输入到信号分析模块分析判断最后输出显示。实验结果表明:系统能正确的接收采集的数据和显示数据,并判断系统数据是否正常,可以应用于该范围内的一般系统监控,也可以用于其它一些接收数据接近的系统当中,此方法生成的监控软件交互性好,性价比高,且实现简单,还可以根据不同的系统对程序进行修改,以满足系统的需要,为低成本构建数据采集提供了一种思路。在LabVIEW环境中实现了对测试系统的监测和控制。
关键词:LabVIEW、数据采集、FOR循环、while循环、信号分析。
The abstract
The control system is mainly based on virtual instruments, and combining the features of the structure of the computer, a computer as a platform, LabVIEW-based monitoring system, which is based on source information collection target, Acquisition of input signal analysis module judgment to determine whether the stability of supervision. In the main control system data acquisition process is input and output, signal analysis, judgment, the results showed. In this procedure will be collected data input to the signal analysis module, analysis showed that the final output. Experimental results show : The system can correct the reception of data acquisition and display data, and data to judge whether it is normal, can be used within the scope of the general system monitoring, and can also be used for other data close to the receiving system, This method of generating interactive control software, and high performance-price ratio, very easy to realize. also under different systems of modifying the program to meet the needs of Construction of low-cost data acquisition with a new idea. In LabVIEW environment to achieve the right test system monitoring and control.
Keywords : LabVIEW, data acquisition, FOR cycle while loops, the signal analysis
