| 摘 要： | 采用LabVIEW虚拟仪器编程,结合数据采集卡和微弱前置放大器,构成了微弱电信号采集系统。通过该系统对不同温度下的橡胶苗电信号进行了测量,得出了橡胶苗电信号时域图、幅频图和功率谱图,然后对测量到的橡胶苗电信号进行小波降噪和分析。最终得出结论:26℃时橡胶苗电信号幅值极显著,比28℃时高;显著高于25℃时,但与27℃时差异不显著。该结论完全符合橡胶树的生长对环境温度的要求(26～27℃)。

| Abstract: | Using Virtual Instrument of LabVIEW,data acquisition card and voltage Pre-amplifier we have built a system.We measured electrical signals at different temperatures through the system and we got the result of time-domain signals,amplitude frequency diagram and power spectrum picture of electrical signals in rubber.We analyzed experimental data based on wavelet function in MATLAB toolbox.We conclude that electrical signals’ amplitude in rubbe at 26℃ is better than at 28℃ and at 25℃,but the amplitude is no notable at 26℃ and at 27℃,which is to reach conclusions that the temperature between 26℃ and 27℃ is suitable for rubber growth. |
