【正文】 、 數(shù)據(jù)采集卡、 計(jì)算機(jī)。 虛擬儀器技術(shù)的核心思想是軟件就是儀器。因此本文在硬件上選用串行數(shù)據(jù)采集系統(tǒng)為研究對(duì)象，以硬件和軟件兩條主線，并在虛擬儀器的思想指導(dǎo)下，對(duì)采集系統(tǒng)的軟件可重組性、數(shù)據(jù)管理等方面展開研究。研究組件技術(shù)和秦氏智能控件模型，提出測(cè)量功能組件的思想，并應(yīng)用到設(shè)計(jì)的虛擬 RS232 采集系統(tǒng)中，將各測(cè)量功能組件化，實(shí)現(xiàn)軟件的可重新組合，拓寬了設(shè)計(jì)的測(cè)量系統(tǒng)的應(yīng)用范圍。 data converters to achieve different types of signal conversion. Detection systems typically include sensor systems, data acquisition, processing, analysis system. Sensor system will be seized signals (pressure, flow, speed, temperature,Vibration, noise and other physical quantities) into electrical signals (voltage or current value), data acquisition, processing, analysis, processing and analysis system will signal the end to plete the data display, storage, printing, transmission and so on. The core idea of virtual instrumentation is software is the instrument. It uses the puter as a control and data Treatment center, part of the traditional instruments by the software instead of hardware, the user can modify the software can be changed by only Instrument function. Therefore, the virtual measurement system, the software functions strengthened, mainly based on signal type of its hardware, real is the signal acquisition. Now, any generation of instruments, the collection features are available, some instruments also have high speed, precision and other characteristics, but also left universal serial mun
