Actual movements compared to the predictions of
the motion pattern
Steady increase in
activty during the last 6
hours. The increase is
certain first at 09.00.
Activity start time will in
this case be 09.00
Obvious increase in
activity between 05.00
and 06.00. Activity start
time will be 06.00
Step 3, The activity meter in work
From now on, the cow's daily movements
are put side by side to the motion pattern's
estimation. Evaluations are made every
hour and include comparisons for the last 6
hours. Any increases in activity are noticed.
The increase must, however, be certain
(statistically significant) before the
processor reports high activity.
A significant increase can be either an
obvious increase in activity during a short
period or a steady increase built up during a
longer period (normally 1-3 hours, maximum
6 hours).
Activity start time
Start time for high activity is set when the
system detects a significant increase.
For cows with a sudden increase in activity
the start time will be set almost directly. For
cows with an increase that is slow but
steady the alarm cannot be set until the
processor has fully determined that the
increase is statistically significant. This
might take 2 -6 hours and the activity start
time will in those case be set 2-6 hours later
than the increase really began.
