PURPOSE: A parking management system using an RFID transmission and reception device to grasp whether a car is parked in each cell of a park sector is provided to receive signals emitted from a plurality of RFID transmission devices without a blind spot. CONSTITUTION: RFID transmitters(10,30) are respectively installed in each cell of parking sectors. At least one RFID receiving device(20,40) forwardly/reversely rotates to expand a signal receiving area for receiving signals emitted from a plurality of RFID transmission devices. By receiving a signal from the RFID receiving device connected to an input terminal, a controller(50) determines whether a car is parked in each cell of the park sectors. A display(70) displays a determination result of the controller. |
