How
about multiple sensors spead over the height of the door. As long as one is
broken the others would be masked.
eg
with single sensors
AB
A ____**____
B______**___
multiple sensors would give something
like
AB
AB
AB
AB
AB
AB
AB
A
_____***********_______
B_______***********_______
As
soon as any bit of the body breaks an A beam it remains broken until all
body
parts are past, likewise the B.
Direction can still be detected from which beam
broke
first. It would avoid problems with height or flailing arms and legs as it
basically addresses the tilt suggested by someone else.
eg
Person walking leg breaks A1,A2,A3,A4 then body breaks A5,A6,A7 etc. As
they are
all in parallel any A beam broken will count as a single valid signal
ending
only when the last beam is restored.
Keith
How
about having the beam breaks pointing vertical?? This way the arms or legs
or
anything don't "break" the beam unless its the body of the
person???
Any
thoughts?
Pedro
Bad
assumption
me =6ft 2
she = 5ft nothing
I think the key to
counting with a beam break is to make some assumptions
about the usage
rather than the height...it is pretty unlikely that people
will go
through a doorway in tandem there will be a discernable break between
people which will be longer than that caused by a single
person.
Test, monitor and fine tune is the way to do it
:)
