USER MANUAL | LR-15: Radar-activated flashing beacons
10
•
SPEED BINS – record monthly speed bins files (enabled/disabled).
•
POWER LOG – record monthly log files of battery voltage (enabled/disabled).
•
OUTBOUND – record the same set of files (excluding power log) for outbound vehicles
(enabled/disabled).
4.3.4 DATE AND TIME SETTINGS
•
SYS TIME – set time for the internal real-time clock.
•
SYS DATE – set the current date for the internal calendar.
4.3.5 ADVANCED SETTINGS
•
SPEED UNITS – system speed units (
KM/H
– kilometers per hour or
MPH
– miles per hour).
•
DEMO MODE – demo mode (activate/disactivate).
•
DISP TRAFFIC – traffic direction used as “displayed” speed (
Inbound
/
Outbound
). This speed will be
used in outputs (beacons and auxiliary) thresholds.
•
DISP SELECT – algorithm of speed selections for cases when more than one vehicle is detected (
CLOSEST
or
FASTEST
)
•
SLEEP CYCLE – number of sleep system cycles that are used when no traffic is detected. Increasing this
parameter helps save battery power but reduces the time of reaction.
4.3.6 RADAR SETTINGS
•
LOWEST SPEED – lowest speed filter set in RSU – radar speed unit. (1RSU = 0,82 km/h). All speeds below
this limit will be rejected.
•
RSSI FILTER – lowest signal level filter is used to reject ambient “noises”. (RSSI – Reflected Signal Strength
Indicator). A lower value will increase the detection range but may result in false detections caused by
small moving objects such as leaves, branches, heavy rain or snow etc.
•
RSSI DELTA – minimal difference between RSSI levels of two separate vehicles (targets) which will result in
the creation of two records. This value can be reduced in a case when the radar undercounts vehicles
(counts multiple vehicles as one).
•
SPEED DELTA – minimal difference between detected speeds which will be considered as a separate
vehicle (in RSU – radar speed unit). This value can be reduced in a case when the radar undercounts
vehicles (counts multiple vehicles as one).
•
STAT CONFIRM – minimal number of samples for each vehicle to confirm the validity of a statistics record
(samples). This value can be reduced in a case when the radar undercounts vehicles (counts multiple
vehicles as one).
•
SIGNAL LOST – number of system cycles that did not return a vehicle speed to consider a vehicle as
passed (disappeared).
•
TARG.CONFIRM – a minimal number of consecutive samples to confirm the “target” as valid.
•
AMP. FACTOR – factor of the radar signal amplification, times:
x1, x2, x5, x10, x20, x50, x100
.
