Description

Animal individual information sensing system and method Technical Field The disclosure relates to the technical field, in particular to an animal individual information sensing system and method. Background With the rapid development of modern animal husbandry to the intensive and large-scale direction, the number and density of animal breeding are continuously increased, and the higher requirements are put on the refinement level of breeding management. Through continuous monitoring of individual physiological states and behavior characteristics of animals, farmers can timely master the health condition, estrus and stress response of the animals, so that scientific data decision basis is provided for accurate feeding, epidemic disease prevention and control and propagation management. However, most of the existing animal ear tags on the market have single functions. The most widely applied radio frequency identification ear tag can only provide an identity recognition function and cannot acquire real-time physiological indexes of animals, and the intelligent ear tag of the part of integrated sensors also mainly stays on a monitoring layer with a single dimension, and particularly has the following obvious technical bottlenecks that first, the body temperature measurement accuracy is easily affected by the environment. Conventional ear tag thermometers are typically provided in only one, and when an animal's activity causes the ear tag to loosen or make poor contact with the skin, the measured temperature is often ambient rather than real body temperature, resulting in data distortion. Second, physiological status recognition functions are lacking. The existing ear tag products can rarely monitor key vital signs such as heart rate and respiration at the same time, and can not evaluate the heart and lung functions of animals in a resting state, so that early respiratory diseases or heart abnormalities are difficult to find. Thirdly, the multi-source data fusion capability is insufficient, and the existing equipment cannot combine the motion gesture with the environmental parameters to comprehensively judge the real state of the animal, so that false alarm and missing alarm are frequently generated.
