【導(dǎo)讀】如何將硬件軟件化，軟件通用化成為虛擬采集系統(tǒng)的研究熱點。本文首先在介紹虛擬儀器和采集系統(tǒng)發(fā)展的基礎(chǔ)上，對采集系統(tǒng)的原理進行分析，系統(tǒng)，16位精度的RS232數(shù)據(jù)采集卡。在LabVIEW軟件環(huán)境下，建立了串行虛。擬數(shù)據(jù)采集系統(tǒng)。隨后剖析軟件結(jié)構(gòu)，結(jié)合組件技術(shù)，提出測量功能組件的思想，LabVIEW提供了很多數(shù)據(jù)存儲的方法,本文采用的是。數(shù)據(jù)存儲和數(shù)據(jù)采集及實時顯示所需要的采用頻率有很。樣頻率的方法過濾掉冗余數(shù)據(jù),減少存儲空間。為此,將采集模塊得到的數(shù)據(jù)設(shè)定兩。一維數(shù)組的方法降低采用頻率,組成新的數(shù)組寫入磁盤保存.傳感器系統(tǒng)將被檢信號(壓。力、流量、速度、溫度、振動、噪聲等物理量)轉(zhuǎn)化為電信號,虛擬儀器技術(shù)的核心思想是軟件就是儀器。備高速、高精度等特點，同時還留有通用的串行通信。現(xiàn)信息的查詢、刪除等功能。軟件的可重新組合，拓寬了設(shè)計的測量系統(tǒng)的應(yīng)用范圍。同時利用LabV工EW的。的運行技術(shù)，實現(xiàn)測量功能組件的集成，這是本文的創(chuàng)新之處。
【正文】 ication. This article used in the hardware serial data mining Collection system as the research object to the two main lines of hardware and software, and the idea of virtual instruments under the guidance of the acquisition software systems data management, and start the study specifically as follows. In the analysis of the function of the hardware ponents and key technology designed and implemented a highprecision serial RS232data acquisition. In software, the first virtual instrument collection of architecture, the choice of the virtual software environment for postdiscussed the capture card driver to implement the method of munication to achieve serial acquisition card. In the analysis of ADO database access technology, working for LabVIEW realize large amount of information presented by LabSQL storage and management, the information query, delete and so on. Of ponent technology and Qin intelligent control model, the ideological measure the functional ponents and applied to set virtual RS232 meter collection system, the functional ponents of each measure, realize the software can be rebination, widened measurement system design applications. LabVIEW while taking advantage of the operation of technology, integration of functional ponents measured, it is the innovation of this article.
