摘　　要：奶牛个体消化食物过程中的甲烷排放量可作为牧场饲喂管理中优化日粮配方的参考依据。为此,设计了一种基于非分散红外(NDIR)技术的奶牛个体甲烷排放检测装置,采用穿戴式结构和低功耗、无线传输技术,通过双波长差分检测技术,利用比尔朗博定律分析计算甲烷气体的浓度。试验结果表明:装置不影响奶牛的日常活动及采食行为,设计的信号处理电路能够有效减少外部干扰,且响应速度块,通过上位机软件实现对数据实时检测。Methane emissions of individual dairy cows during food digestion can be used as a reference for optimization of dietary formula in pasture feeding management.In this paper,an individual methane emission detection device for dairy cows based on non-dispersible infrared(NDIR)technology is designed.It adopts wearable structure,low power consumption and wireless transmission technology,and adopts dual-wavelength differential detection technology.The concentration of methane gas is calculated by using the analysis of Billebeau's law.The device does not affect the daily activities and feeding behavior of cows.The designed signal processing circuit can effectively reduce the external interference.The response speed block can realize the real-time detection of data through the upper computer software.
