But the disadvantages are heavy communication cost and corresponding influence on enegy cost , network communication load and positioning time 但其不足在于定位過程通信開銷過大,進(jìn)而對節(jié)點能耗、網(wǎng)絡(luò)通信負(fù)載和定位時耗都造成不良影響。
Virtual instrumentation is composed of the computer resource , instrumentation and user interface which is used to analyse data and communicate . remote virtual instrumentation is extended from virtual instrumentation in network ; it can complete information collection , transmission and processing incorporation 虛擬儀器是計算機(jī)資源和儀器硬件與用于數(shù)據(jù)分析、過程通信及用戶圖形界面的軟件的有效結(jié)合,而遠(yuǎn)程虛擬儀器則是虛擬儀器在網(wǎng)絡(luò)領(lǐng)域的擴(kuò)展,使信息采集、傳輸和處理一體化,實現(xiàn)了資源的共享。
The test system we discussed is made up of a personal computer , hard wares with various functions , graphical interfaces application software labwindows / cvi which is used to analyses data and process communication . it made the computer to be a numeral platform with various test functions 本課題建立的測試系統(tǒng)由個人計算機(jī)、各種功能硬件模塊與用于數(shù)據(jù)分析、過程通信及圖形用戶界面的應(yīng)用軟件labwindows cvi有機(jī)結(jié)合構(gòu)成,使計算機(jī)成為一個具有各種測量功能的數(shù)字化測量平臺。
