Carpark Master Zone Counter (MZC)
Introduction
The Master Zone Counter (MZC) is part of the Dupline® Carpark 3 system. The MZC is a counting system
which is able to detect and count cars when they enter and exit zones in the Carpark facility and send the
information to displays and the Dupline® Carpark software for display on a computer.
To make the MZC system fully compatible with the single-space detection system, the MZC transmits its
count values by emulating a number of single-space segments. This means that the values for the displays
are broadcasted on the 3-wire Dupline® bus. Also, the values are displayable in the SBP2CPY24, so that they
can be used in the Carpark software equal to the data from the standard space-by-space system.
The MZC system is often used in a single-space system to keep track of the cars on the rooftop, where no
ultrasonic single-space sensors can be installed. It can also be used to implement a complete parking
guidance system at a lower cost than a single-space system.
Hardware
The MZC is using the same hardware as the standard Carpark guiding system:
SBP2MCG324 - Carpark master generator
SBP2WEB24 - Carpark controller
SBP2CPY24 - Carpark server
SBPSUSCNT - Carpark Count sensor
If a stand-alone counting system is required, the customer will need these modules.
If the customer already has a space-by-space system but want to add a count solution on a rooftop, it
would suffice to add an SBP2MCG324 for the count part. The software for the MZC is already built into the
SBP2WEB24 and the SBP2CPY24.
Sensor
The counting system needs a specially designed sensor for counting. The SBPSUSCNT is a vertical sensor
with a rapid detection principle. This means it can count cars running up to 20 Km/h. The sensor is to be
mounted in the driving lane The sensor is to be mounted in the driving lane at the height of 2.0 to 2.5 m
from the floor level pointing directly towards the floor. When a car passes beneath the sensor, the signal is
transmitted to the Carpark system as an entry or an exit. The sensor uses the 3-wire Dupline® bus and must
be installed in the same way as other Dupline® Carpark 3 sensors. Use the same installation rules as for the
standard Carpark 3 sensors:
