Calf state monitoring device and method based on behavior characteristics spectrum linkage

Abstract

Disclosed is a calf state monitoring device and method based on behavior characteristics spectrum linkage. The device comprises double video cameras, an exchanger, a computer, an external controller and an external actuator, the cameras are connected with the computer through the exchanger, the cameras collect calf activity videos which serve as signal input of a monitoring system, the computer analyzes the videos to obtain individual calf states and behavior information to perform fuzzy reasoning so as to obtain controlled quantity and alarm parameters, the external controller is connected with the computer through a serial port to receive control parameters, working parameters of the external actuator are adjusted so as to improve calf breeding environments, and an SIM communication device is used for sending an alarm short message. According to the calf state monitoring device and method based on behavior characteristics spectrum linkage, the two cameras are applied and an image analysis technology is combined, all-weather monitoring is performed on calf behavior information and state parameters, environmental adjustment and controlling is performed according to individual state parameters, and problems of individual calf behavior information collection and utilization during animal production can be solved.

Description

technical field [0001] This patent belongs to the technical field of dairy cow individual behavior state monitoring, and in particular relates to a device and method for calves state monitoring based on behavior characteristic spectrum linkage, which has abnormal alarm and environment control functions. Background technique [0002] Large-scale dairy cow breeding is an effective way to improve the efficiency and level of dairy cow production, increase farmers' income, improve the quality and safety of dairy products, improve the ability to prevent and control diseases, and achieve the coordinated development of animal husbandry and the environment. Large-scale farming has brought new challenges and requirements to feeding management methods and methods. Since there are differences in age, parity, and lactation stage among individuals in dairy cows, and the difference in milk production between individuals is greater than that between breeds, the feeding of dairy cows must ta...

AI Technical Summary

Problems solved by technology

The above research has improved the efficiency and accuracy of dairy cow information acquisition, but usually a sensor can only monitor a single information, the system hardware cost is high, and the dairy cow breeding environment is harsh, the sensor is easy to fall off and lost, and it will cause certain damage to the cow's body , the system maintenance is difficult, and it is difficult to apply it to the entire cattle farm; most of the collected information is the external physical parameters of the cows, it is difficult to monitor the advanced behavior of the cows, and it is even more difficult to know the internal pathological and physiological information of the cows; The control system adopts open-loop control, with a fixed threshold as the control parameter, and the external environment parameters are unstable, so it is difficult for the system to work in a stable state, and the energy efficiency is high, and the control effect is difficult to guarantee.

[0004] In addition, the mortality rate of newborn calves is high, so calves under the age of 6 months need to be placed in a calf pen for fine feeding and management, but there is no report on the automatic system for information collection of calves

At present, dairy farms use manual regular inspections to care for calves, which not only wastes manpower and material resources, it is difficult to ensure the breeding environment of calves, and it is even more difficult to find abnormal pathological behaviors of calves in time, which can easily lead to accidental premature death of calves
