- If set, the operation weekdays of the other parameter sets must be discarded.
2. You want to measure at a road construction site by night from 19:00 till 06:00 display the
vehicle driver’s speed. But you want to measure the whole day around the clock.
Following settings must be made in parameter set 1 in the time schedule menu:
- Set LED display to „on“.
- Change the operation weekdays to „ Su,Mo,Tu,We,Th,Fr,Sa “.
- Set the daily start time to „19:00“ and the daily stop time to „06:00“
Additionally following settings need to be done in parameter set 2 in the time schedule menu:
- Set LED display to „off“.
- Change the operation weekdays to „ Su,Mo,Tu,We,Th,Fr,Sa “.
- Set the daily start time to „6:00“and the daily stop time to „19:00“
In the second example with the time schedule of parameter set 1 a measurement with numeric
speed display is made from 19:00 till 6:00 o’clock each night. During the daytime from 06:00
till 19:00 o’clock the time schedule of parameter set 2 measures without displaying the speed
on the numeric LED display.
6.3.3 Bidirectional detection
The viasis radar detects also the data of leaving vehicles, whose data by default are not stored
in memory and whose speed in principle are not shown on the numeric LED display. The fea-
ture
Bidirectional detection
allows an additional memorization of data of leaving vehicles for
later data evaluation purposes.
If you enter
3
in the „Settings” menu you are prompted to change the
Bidirectional detection
state:
Bidirectional detection
1. off
2. on
Your choice 1...2?
Is the
Bidirectional detection
set to “on” you are given in the
Online measurement
menu the
speed data of vehicles of both driving directions by the serial data connection(s), see chapter
6.6.
Hint: The bidirectional detection delivers only at low traffic density, respectively low
vehicle meeting rate, complete and meaningful data for the leaving vehicle traffic,
whose vehicles cannot be detected as long they are in the radar shadow of approach-
ing vehicles.
The setting for the
Bidirectional detection
is valid for all parameter sets. In viagraph the fea-
ture
Both directions
can be activated in the
Tools
menu of the
Settings
window.
