Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] An embodiment of the present invention provides a system for detecting the presence or absence of a vehicle. The presence or absence of a vehicle in a parking space is detected by means of radio frequency, which will be described in detail below.

[0034] Fig. 2 is a judgment flow chart of a system for detecting the presence or absence of vehicles disclosed in the present invention. The system needs to place a transponder in the detected parking space, and install a reader that can read the transpo...

Abstract

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

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a system for detecting the presence of vehicles by radio frequency identification. Background technique [0002] For large parking lots 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. In idle time, 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 sensing method, geomagnetic method and video recognition method. Among them, the ultrasonic method is the most common application in the parking guidance system...
