AI Technical Summary
[0004]然而，上述中国专利CN 116267692 A在开放或半开放环境中易受风速等气象条件干扰，检测稳定性较差；国际发明专利CA2796450A1适用范围较小，只能针对某一具体动物进行检测；中国专利CN219552387U料槽结构固定、适配性不足，难以同时兼容不同体型（如牛与羊）个体的稳定采样；同时，在开放式养殖环境中，其集气孔存在易堵塞、气体回收效率低等问题，由此可见，采用当前的反刍动物呼出甲烷采集与监测方案，采集兼容性、采集效率和监测准确性仍较低
[0034]The ruminant multimodal sensing biomimetic feeding and gas collection device provided in this application includes: a frame housing, a biomimetic feeding trough, a cavity partition, a three-dimensional gas collection partition, a negative pressure fan, an adjustable side plate, a feeder, a time-of-flight (TOF) sensor, an LED light array, an acrylic plate, and a controller. The controller is communicatively connected to the negative pressure fan, the feeder, the TOF sensor, and the LED light array. The adjustable side plate is fixed to the outside of the opening side of the frame housing by multiple locking components. The frame housing has a first cavity and a second cavity, with the first cavity accessed through an adjustable opening in the adjustable side plate. The system is connected to the outside; the cavity partition is disposed between the first cavity and the second cavity; the negative pressure fan is fixedly disposed at the bottom of the second cavity; the air inlet of the negative pressure fan communicates with the first cavity through a through hole disposed on the cavity partition; the air outlet of the negative pressure fan communicates with the outside through an air outlet pipe passing through the frame housing; the biomimetic feeding trough is disposed at the bottom of the first cavity; the main body of the biomimetic feeding trough is made of food-grade antistatic plastic with a surface resistance of <106Ω; the bottom of the biomimetic feeding trough has an elliptical slope biomimetic structure; the three-dimensional gas collection partition surrounds the biomimetic feeding trough; the three-dimensional gas collection partition... The plate includes: a gas collection plane, a gas collection slope, and a side panel. The gas collection plane is arranged parallel to the cavity partition, and the gas collection slope is arranged opposite to the air inlet of the negative pressure fan. Multiple gas collecting holes are provided on the gas collection plane, the gas collection slope, and the side panel. The diameter of each gas collecting hole is 3 mm, and the density of the gas collecting holes on the gas collection plane is 25 holes/dm², so that the negative pressure fan can extract gas from the first cavity at a gas flow rate of 0.3-0.8 m³/min through the gas collecting holes and the through holes in the cavity partition. The feeder is located on the first... Within the cavity, the feed inlet of the feeder communicates with the outside through an opening at the top of the frame housing, and the discharge outlet of the feeder communicates with the biomimetic feeding trough. Multiple Time-of-Flight (TOF) sensors are disposed within the first cavity, used to monitor the head posture and feeding rhythm of the ruminant during feeding. An LED light array and an acrylic plate are disposed within the first cavity; the LED light array is located at the top of the first cavity, and the acrylic plate is located on the side wall of the first cavity. The acrylic plate is used in conjunction with the LED light array to form alternating bright and dark light spots in the 450-600nm wavelength range.In this embodiment, multiple Time-of-Flight (TOF) sensors monitor the approach of ruminants. When a ruminant approaches, an LED light array is activated, creating an enticing light spot in conjunction with an acrylic plate. This induces the ruminant to insert its head into the first cavity to feed. During the feeding process, the TOF sensors continuously monitor the ruminant's head posture and feeding rhythm. This allows for the activation of a negative pressure fan during the stable and continuous feeding process of the ruminant, collecting the exhaled gas through holes in the three-dimensional gas collection partition. This improves the compatibility, efficiency, and accuracy of methane collection from ruminant exhalations.
