Abstract

The invention relates to the technical field of methane emission, and discloses an intelligent detection system for measuring bovine methane emission, which comprises a methane emission detection system, the methane emission detection system comprises a gas inlet system, a collection system, an exhaust system and a processing system; the air inlet system comprises a feed control module, an air flowing module, a feed mobile phone module and an air inlet concentration module; the acquisition system comprises an RFID reader, a head position sensor, an infrared absorption spectrometer and a head respiration detection module. According to the invention, the detection technology of the infrared absorption spectrometer has high accuracy on methane emission of cattle, does not interfere with the action of animals, can carry out real-time monitoring, and has huge advantages under the grazing condition, air can be updated in time conveniently through the air inlet and exhaust system, the situation of detecting the same group of data is avoided, the accuracy of the data is improved, and the detection cost is reduced. The effect of improving the accuracy of detecting the methane emission of the cattle is achieved, and the influence of constraint on the cattle is avoided.

Description

technical field [0001] The invention relates to the technical field of methane emission, in particular to an intelligent detection system for measuring cattle methane emission. Background technique [0002] Methane is an organic compound with a molecular formula of CH4 and a molecular weight of 16.043. Methane is the simplest organic substance and the hydrocarbon with the least carbon content (the most hydrogen content). Methane is widely distributed in nature and is the main component of natural gas, biogas, pit gas, etc., commonly known as gas. It can be used as fuel and raw material for the manufacture of hydrogen, carbon black, carbon monoxide, acetylene, hydrocyanic acid and formaldehyde. consists of one carbon and four hydrogen atoms through sp 3 The structure of the methane molecule is a regular tetrahedral structure, and the bond lengths of the four bonds are the same and the bond angles are equal. Methane is a colorless, odorless gas under standard conditions. ...
