Garage Positioning System and Method Based on RFID Recognition

Abstract

The invention discloses a positioning system and a positioning method in a garage based on RFID recognition. There are RFID readers with the number of a (1) and RFID read-write trigger devices with the number of b (2) in a garage. Each RFID read-write trigger device (2) is wired / wireless connected with an RFID reader (1) in the detection area; and an RFID reader is connected to a garage server. AnRFID read-write trigger device (2) sends a trigger signal to an RFID reader (1) after detecting a vehicle / person, so that the RFID reader (1) reads the RFID tag of the vehicle / person. Beneficial effects are that an RFID read-write trigger device will start an RFID reader only when a vehicle / person enters the detection area of the RFID read-write trigger device and the device detects the presenceof the vehicle / person, and the energy consumption of an RFID read-write trigger device is lower than that of an RFID reader, which makes the RFID reader not open frequently and saves energy consumption.

Description

technical field [0001] The invention relates to the technical field of garage positioning, in particular to a positioning system and a positioning method in a garage based on RFID identification. Background technique [0002] With the development of information technology, no matter where people are, they can know the current location through the electronic map, so as to obtain the surrounding situation and formulate the target plan. However, since most electronic maps are positioned based on satellite technologies such as GPS or Beidou, they can only provide positioning information in areas without signal occlusion, and cannot accurately locate in indoor or underground scenarios. Other methods are needed to provide users with accurate positioning services . [0003] The garage is one of the indoor scenes that most require accurate positioning. In a completely unfamiliar garage, the owner's parking, car search, and entry and exit routes all need to be solved through positio...

Problems solved by technology

And the existing RFID positioning method is still not perfect, as the application number 201710303108.6, the patent name is the positioning method disclosed in the RFID-based underground garage intelligent positioning and dynamic display system and method, still needs the mobile terminal (4) to transmit information to the car owner, Using a mobile terminal while driving is dangerous, so the method is less practical

Furthermore, RFID radio frequency signals have different signal ranges according to different frequency bands. Higher frequency bands have a larger signal range, but also consume more energy. RFID equipment, the cost is greatly increased
