Parking lot charging method based on FRID

Abstract

The invention discloses a parking lot charging method based on RFID. The parking lot charging method comprises the steps that when a vehicle runs into a parking lot, the time when the vehicle runs into the parking lot is written to an RFID tag card, and the RFID tag is delivered to the driver of the vehicle; before a user leaves the parking lot, the user pays the parking fare through a paying device in the parking lot, and the time when the user pays the parking fare and the amount of the parking fare are written into the RFID tag card; the user hands over the RFID tag card at the exit of the parking lot, the time during which the user stays in the parking lot after paying is calculated, whether the user needs to pay again or not is judged according to the staying time, and if the user does not need to pay again, the user is allowed to pass through the exit. According to the parking lot charging method based on RFID, the structure is simple, use is convenient, the charging link is conducted in advance, charging sites are distributed to all charging devices of the parking lots, and the phenomenon that a traffic jam is caused at the exit of the parking lot is effectively avoided.

Description

technical field [0001] The invention relates to a parking automation system, in particular to an RFID-based charging method for a parking lot. Background technique [0002] RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification, which is a non-contact automatic identification technology. It automatically identifies the target object through radio frequency signals, and can quickly track items and exchange data. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient. RFID technology was born during World War II. It is the successor of traditional barcode technology, also known as "electronic tag". [0003] In the specific application process of the RFID system, the composition of the RFID system will be different according to different ap...

[0010] This method is to avoid traffic jams by installing smart on-board equipment on the vehicle and performing high-speed calculation and settlement at the exit of the parking lot through the smart on-board equipment. However, this method requires a relatively large investment and requires each car owner to actively set up Smart on-board equipment is not very practical, and it is easy to be incompatible between different parking lots
