摘要
采用U12数据采集卡和微弱信号放大器、以LABVIEW为软件开发平台,设计了植物电信号采集虚拟仪器试验系统,利用该试验系统可以对植物电位信号进行数据采集,初步建立了"植物—电信号获取—电信号的调理—计算机信息数据处理—数据波形显示—数据分析"系统。
Basing of LabVIEW for platform of software development,we designed an experiment system of virtual instrument,which is used to obtain electrical signals in plants by data acquisition of U12 and pre-amplifier.With the help of the system,we can obtain large numbers of the plant electrical signal.We set up the plant--the electric wave signal obtaining--signal modulating--the computer information data processing--wave displaying--the plant electric wave signal characteristic analyzing.
