Abstract: A vehicle parking network comprises a transmitter-responder device (TRD) for each subscriber and a complementary box which can be coupled to the TRD and only to it, and permits it to communicate with a central computer. The complementary box is provided with identification marks that can be scanned from the outside and includes a microcontroller, memory means and timing means. Once the vehicle is parked, the TRD is used to obtain from the computer a parking authorization and an allowed parking time. Then a legitimate parking sign is displayed and the parking time is down counted until the allowed time has been completed or until the vehicle leaves the parking space. If communication with the computer cannot be established, the complementary box carries out an assumed parking procedure, stores its data in a buffer memory, and later transmits them to the computer for verification and registration.
