針對(duì)眾多低成本數(shù)據(jù)采集需求，采用帶有片上USB控制器和D/A轉(zhuǎn)換器的混合信號(hào)微處理器C8051F340，設(shè)計(jì)了一款可通過USB接口和LabVIEW圖形用戶界面實(shí)現(xiàn)與PC機(jī)聯(lián)機(jī)的數(shù)據(jù)采集器，同時(shí)借助系統(tǒng)的SD卡存儲(chǔ)獨(dú)立實(shí)現(xiàn)現(xiàn)場長時(shí)間采集數(shù)據(jù)。該數(shù)據(jù)采集器成本低，結(jié)構(gòu)簡單，體積小，已成功用于工業(yè)現(xiàn)場。
Abstract:
Aiming at the need of low cost data acquisition, a data acquisition device is designed based on C8051F340 which is a mixed-signal microcontroller and integrates USB controller and A/D controller on a chip.The data acquisition device which can combine with PC by USB interface and LabVIEW graphical user interface,can realize data acquisition. At the same time,it can be solely run a long time in virtue of SD card in field.The date aequisition device features low cost,simple structure and little sharp, and it has been used in industry field.
