Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0027] refer to figure 1 , an RFID system capable of detecting vehicles, comprising: an antenna, a transceiver signal splitter, a transmitter, a receiver, a reflected signal strength detector, a reflected signal strength comparator and a controller;

[0028] Wherein, the antenna is responsible for transmitting and receiving RF signals;

[0029] The transceiver signal separator is responsible for separating the signal transmitted by the antenna from the reflected signal received by the antenna, and the separated received (essentially reflected) signal is sent to the receiver;

[0030] The receiver is responsible for amplifying the received signal, demodulating and decoding the ref...

Abstract

The invention discloses an RFID system capable of detecting a vehicle. The RFID system capable of detecting the vehicle comprises an antenna, a transceiving signal separator, a transmitter, a receiver, a reflected signal intensity detector, a reflected signal intensity comparator and a controller, wherein the antenna is responsible for transmitting and receiving RF signals; the receiving and transmitting signal separator is responsible for separating signals transmitted by the antenna from reflected signals received by the antenna, and sending the separated received (essentially reflected) signals to the receiver; the receiver is responsible for amplifying and demodulating the received signal and decoding the reflection code information of the RFID card; the reflection signal intensity detector is responsible for detecting reflection signals of the non-RFID reflection codes and sending the signals to the reflection signal intensity comparator. The beneficial effects of the system are that the system can recognize and detect vehicles.

Description

technical field [0001] The invention relates to the field of detecting vehicles, in particular to an RFID system capable of detecting vehicles. Background technique [0002] In parking lot applications, whether the parking space is occupied by vehicles is generally realized by geomagnetic, infrared or ultrasonic radar. [0003] The traditional technology has the following technical problems: [0004] However, these methods can only detect whether there is a car in the parking space, but cannot know which car it is, so that it is necessary to use vehicle recognition technology as a supplement in order to collect parking fees. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide an RFID system capable of detecting vehicles, which can both identify vehicles and detect vehicles. [0006] In order to solve the above-mentioned technical problems, the present invention provides a kind of RFID system that can detect vehicle...
