How the activitymeter works
A cow's movements, hour by hour for 5 days
Step1, Watching the cow
The first five days the activity meter is in
use, the processor records the cow's
movements to learn how she usually moves.
During these days high activity attentions
are reported, but only after 5 days such a
report should be considered reliable.
Each bar in the diagram represents the
number of movements the cow has made
during one hour.
A calculated motion pattern for 24 hours
Step 2, Identifying a motion pattern
The processor now uses the data from all
the days of recording to make an advanced
statistical calculation. For each hour of the
day, the movements of every single cow are
considered. The calculation results in a
motion pattern, which shows the cow's
motion and resting periods during a normal
day.
The motion pattern is continously updated.
Every hour new data are included in the
calculation. The latest sending will always
have the greatest effect on the calculation
and earlier data will gradually loose
importance. In this way the motion pattern
will follow any changes in the cow's normal
way of behaviour.
