The basic idea of the project is that when a parker enters into parking system through an entry terminal, the parker gets a ticket from a Card Printer. The ticket consists of Time-in of the parker and one Parker ID. The parker is allowed to leave the parking system through an exit terminal only after he /she pays through the cash automat.

The Visual Basic interface part communicates with the main program (written in C++) which is running in a central computer. This interface checks the Device Status, Sector Position (in other words, number of parking spaces) and Barrier Opening.

In the Visual C++ interface part, there is one main program running in a central computer. This main program polls the devices, such as entry terminals. There is another module in the system which mainly consists of some databases & implementation of some DLL functions. Through these DLL functions when a parker enters or leaves the parking space, the database is updated. The exit is allowed only when the parker pays the amount during which he / she stayed. All these information are updated in the database.

Environment: Visual C++, Visual Basic, MS Access
