Design of Automatic System to Detect Cow Oestrus

A step counter for collecting cow activity information is designed to detect cow oestrus because cow increases movements obviously in oestrus period.The information collected is transmitted to upper computer management system by wireless transmission.With the assistant of step counter,cow administrators can judge whether cow is in oestrus period in time.Low power consumed is the key for design the step counter and many measures are taken to reduce power consumed.The microprocessor and wireless communication module are initialized in low power consumed mode.The information collecting and wireless communication are realized by interrupt mode.Many experiments are done to test the reliability and veracity in the library and cattle farm,the veracity rate of the counter steps is up to 99%.
