6. Designing the placement of displays
1. Define the number of displays based on the natural flow of cars in the parking facility, by
making a walk-through or drive-through with the customer.
2. Take any architectural considerations with the customer regarding signals, finding the
drivers’ way and any other equipment to be installed in the parking facility.
3. Split the parking into segments using the lanes.
4. Define the type of display content (arrow, red-cross, available bay counting) according to
the natural flow and to
the customer’s requests or needs.
5. Determine the necessary environmental ratings of the displays according to the intended
use and installation.
Note: you should also take into consideration the accidental water ingress from plumbing
leaks and wind-blown rain or snow.
6. Decide if there should be one or more multi-level
‘Tower’ or ‘Totem’ displays installed at the
entrance of the parking, providing a snapshot of all the available bays on each level.
What should the displays show?
Several available bays in many lanes or just local available bays of a single lane.
Each display is connected to a display interface, which also has a SIN number. The display
interface is connected to the same Dupline® bus as the Carpark sensors. The display can be
placed anywhere on the Dupline® bus and on any CMCG in the system. The data to be shown on
the display are available on any Dupline® bus of the entire Carpark system.
7. Designing the placement of cable trays and cabinets
1.
Determine the number and placement of the cabinets.
Notes:
•
The cabinets should be placed so that the sensor loads are equal in all directions.
•
They should be accessible only by ladder or cherry picker so as to be protected
from tampering.
•
The maximum rating of the enclosures should be NEMA 3R or IP54.
2.
Use aesthetic cable rails, where sensors can be installed and cables can be pulled and
mounted.
3.
Place cabinets in a logical way with short distances to the lanes to avoid long cables.
For example, place many small cabinets in the area or on the floor or place a big cabinet in
the middle of the area or floor
.
Example 1: a one-floor system
The diagram below is a example of how to implement 477 sensors on a single floor. Additional
floors would be configured, installed and brought online in the same way. Refer to section
