Title: SMART PARKING FACILITY MANAGEMENT BY USING WIRELESS COMMUNICATION TECHNIQUES TO PERFORM STATIONARY AND MOVING VEHICLE DETECTION
Abstract:
Systems and methods for detecting occupancy of at least one parking space by a vehicle are described. Detecting occupancy of at least one parking space includes at least one tag device fixed to a respective one of the at least one parking space. A first reader device is configured to interrogated the at least one tag device and detect a reply signal from the at least one tag device. A processor is configured to analyze the reply signal from the tag device including analyzing a received signal strength indication and a differential phase change of the reply signal to determine the presence of a vehicle in the parking space due to interference of the received signal by a signal blocking body.
