Abstract

The invention relates to a method for detecting presence of a vehicle. The method comprises steps that a reader 10 is mounted above a detected parking stall, a transponder 30 is mounted at the detected parking stall, as the vehicle body metal object has the function of shielding radio frequency signals, when a response signal from the transponder 30 can be received by the reader 10, the detected parking stall is determined to have no vehicle 20, when the reader 10 is unable to receive the response signal from the transponder 30, the detected parking stall is determined to have the vehicle 20.The invention further discloses a system for detecting presence of the vehicle. The system comprises the reader 10 and the transponder 30, wherein the reader 10 is used for reading the information stored by the transponder 30. As the vehicle body metal object has the function of shielding the radio frequency signals, when the reader 10 is unable to receive the response signal from the transponder30, the detected parking stall is determined to have the vehicle, when the response signal from the transponder 30 can be received by the reader 10, the detected parking stall is determined to have novehicle.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a method and a system for detecting the presence of vehicles by radio frequency identification. Background technique [0002] In a large parking lot with many parking spaces, the parking guidance system needs to accurately detect whether each parking space is free, that is, to detect whether there is a vehicle in each parking space. Due to the large number of parking spaces in the parking lot, in order to achieve accurate real-time detection of parking spaces Whether it is free or not, it is necessary to install detection equipment in each parking space. The installation work is relatively large, and the maintenance cost of the equipment during use is also relatively high. As a result, the parking space detection system cannot be widely used. [0003] At present, the main methods for detecting the existence of vehicles include: ultrasonic method, ground sensi...
