PURPOSE: An IP-USN based unmanned parking system is provided to enable a user to check a parking charge in real time by sensing a vehicle and transmitting data to a P&D server. CONSTITUTION: An IP-USN based unmanned parking system includes a sensor(10) and a P&D(25). The sensor senses a vehicle and transmits the first sensing data for sensing a vehicle at a corresponding section to the P&D through a wireless relay. The P&D starts parking charge counting about the sensed vehicle by receiving the first sensing data. The sensor transmits the second sensing data for sensing the parking finish to the P&D through the wireless relay. The P&D finishes the parking charge counting and settles the parking charge. |
