페이지 인쇄The counter has been designed so it cannot be tripped by falling leaves, walking
sticks swung by hikers or other small objects, and to not register more than one
count for long objects like horses and cycles. It has also been redesigned to not
"run away" count in heavy rain or fog. The traffic counter will operate about 12
months on 4 "D" cell flashlight batteries. We recommend you install batteries
each fall.

Theory of Operation:
The TTC-4420 is a portable, battery operated, active infrared trail counter
utilizing presence detection. With the exception of the output and input
amplifiers, the unit has been fully digitized for increased accuracy and battery
life. The TTC-4420 collects data in hourly intervals and the grand total. All data
can be read off the counter display using the magnet to key "up" data.
Optionally, an RS-232 serial port can be installed that can be read using the Data
Hog and in the future a PDA.
Two circuits are employed—one circuit controls the pulsed infrared beam,
detects hikers and sends a trigger pulse to the second circuit that displays and
stores count data in memory.
Units with the time interval count recording feature record the count for hourly
intervals into memory. The one hour time interval is a factory setting. Computer
software can be used to yield count totals for 6 hours, 12 hours, one day,
weekly, or monthly, etc. Software to accept and analyze data is available from
Diamond Traffic Products.
Note: The counter can measure the passage of time but does not know the
correct time of day. It starts measuring hourly intervals a few seconds after you
set it up.
