Zone counting system with split between standard and reserved
spaces
It is a common issue with zone count systems in parking facilities that they are not able to detect the
split between standard and reserved spaces, typically used for handicap or VIP spaces� So, even if
the signs outside the parking are showing that spaces are available, the driver may find that there are
no spaces in the required category available�
The Dupline zone count system offers the option to detect the split between standard and reserved
spaces� The reserved spaces are implemented as a single spot system where each space is equipped
with a carpark sensor� The accurate reserved space availability information hereby achieved is linked
to the Zone Counter which can calculate the available standard spaces from the total amount� The
end result is that the signs outside the parking can show how many spaces are available for each
category� As a further benefit, the system makes it easier for disabled people to find the handicap
spaces, which have individual blue LED indicators� In the case of reserved VIP spaces, the indication
could be amber LED indicators�
When implementing this solution, the MZC needs to know on which L2 slave address can be read the
required available data from the handicap single spot system� So, all the sensors used for handicap
spaces must be connected to the same single spot L1, and a slave carpark monitor has to monitor
these sensors and send the number of available spaces as a value on a specific L2 ID which is re-
quired when the MZC for this solution is configured (see configuration section)�
