Method and device for reverse car locating in parking lot by composite RFID (radio frequency identification device) card

Abstract

The invention relates to a method and a device for reverse car locating in a parking lot by a composite RFID (radio frequency identification device) card. The method is characterized by including: 1) a parking card is set as the composite RFID card, and a long-distance RFID module and a short-distance RFID module are arranged inside the parking card; 2) a plurality of RFID locating antennas are arranged in the parking lot so as to form an RFID locating structure; 3) when a car owner gets the card, an entrance card dispenser writes vehicle information about a license number and the like into the short-distance RFID module; 4) the RFID locating antennas read information of the composite RFID card and a vehicle information management and control center obtains a located area of the composite RFID card; 5) a vehicle information input and display terminal displays information such as a vehicle photograph, the related located area and how to head for the area for the car owner. The method has the advantages that the composite RFID card is diversified in shape, highly durable and good in transmission, and the method is accurate in car locating position, low in production cost, lower in manufacture and operation costs and the like.

Description

technical field [0001] The invention relates to a reverse car search method and device using a compound RFID card in a parking lot, which is suitable for reverse car search in a parking lot in a building. The utility model belongs to the technical field of vehicle management. Background technique [0002] At present, the construction area of ​​the parking lot is getting larger and larger, and often has a multi-layer structure. Its regional division is also becoming more and more complicated. It is easy for car owners to park, but it is difficult to find a car from time to time. Therefore, some intelligent parking lots provide a reverse car search system to improve the efficiency of car owners. [0003] In the prior art, there are mainly three kinds of reverse car-finding technologies: one is the card-swiping positioning technology, which utilizes the card-swiping terminals distributed in various areas in the parking lot to locate. Swipe the card on the locator, and the da...
