摘要
提出了一种基于Lab Windows/CVI虚拟仪器平台的奶牛采食量自动检测系统设计方案。根据奶牛采食行为特征,采用压电式传感器获取奶牛采食信号,对这些信号进行采集,在上位机虚拟仪器平台上完成信号的再次处理、进一步的分析以及人机界面的构建。基于虚拟仪器的奶牛采食量检测系统充分利用了PC资源,使用方便,结果准确。
This paper proposes a design which is based on Lab Windows / CVI virtual instrument platform dairy cows＇ automatic detection system.According to the feature of the dairy cow when it is taking food.It uses piezoelectric sensors for dairy cows signal and a data acquisition card to capture these signals.In the PC virtual instrument platform,it completes the information re-treatment,further analysis and construction of human-machine interface.The design makes full use of PC resources.It is easy to use and accurate.
