Technical description of the installation
Above each parking slot is placed a photo detector which registers if a car is using the parking slot. Each detector is equipped with a DPBIT21 passiv counter enabling a central computer to monitor all the parking slots in the car-park. DPBIT70 active counters are also being used to monitor traffic flow in the car-park.
Using the same 2-wire bus cable the central computer is connected to information screens, electronical signs, lighting and gates. A BIT2114 server, DPBIT68 analog input components and a BIT2000 industrial mini PC are used for these purposes. All this enables the computer to control the car-park according to the many rules and functions in the customized Bitlink software.
