The invention relates to an intelligent
ear tag suitable for free-
ranging goats. The tag comprises an
ear tag body, a controller, a hear rate monitoring device, a tri-axis
accelerometer, a
GPS positioning device, a
wireless communication module, a storage battery, a temperature sensor, a photovoltaic battery piece, a warning device and a relaxation device for beasts, wherein the controller, the heat rate monitoring device, the tri-axis
accelerometer, the
GPS positioning device, the
wireless communication module and the storage battery are arranged in the
ear tag body, and the temperature sensor, the photovoltaic battery piece, the warning device and the relaxation device are arranged on the outer portion of the ear tag body; the temperature sensor is fixedly connected with the ear tag body through a piece of soft belt, the photovoltaic battery piece is a
flexible battery piece and wraps the outer surface of the ear tag body, and the warning device and the relaxation device for beasts are fixedly connected with the outer surface of the ear tag body. According to the intelligent ear tag, the
heart rate, moving condition and position of the free-
ranging goats can be monitored in real time, the goats can be pacified and relaxed in excessive movement, and the situation that the excessive movement influences weight increment is avoided; meanwhile, the outer in-
ear temperature sensor can precisely monitor the temperature.
