Problems solved by technology

However, the system needs to deploy a large number of readers, and the cost of the readers is relatively high, so the cost of the entire system is relatively high
In addition, in the fixed reader solution, the reader and the tag may be temporarily blocked by obstacles, so the accuracy will be greatly affected by the environment

Abstract

The invention discloses a RFID reference location system, which comprises the following parts: several RFID reference tags, several RFID object tags, several mobile RFID readers, information server and customer end, wherein the RFID reference tag is fixed on the fixing object within the system cover scale; the RFID object tag is set on the pre-located object; the mobile RFID reader is set on the mobile carrier to move within the system cover scale along with the mobile carrier, which affirms the object position; the customer end connects the information server through LAN, which provides operational interface for user; the pre-located object is loaded by mobile carrier; the mobile reader reads the tag and reference tag on the pre-located object, which sends the read information to the information server at wireless pattern; the information server affirms the position of object and mobile carrier.

Description

technical field [0001] The present invention relates to a reference positioning system, in particular to a reference positioning system utilizing radio frequency identification technology (hereinafter referred to as "RFID": radio frequency identification, also referred to as an electronic tag). It uses a combination of mobile RFID readers and RFID tags to locate the precise location of objects. Background technique [0002] With the development of communication technology, various positioning systems emerge as the times require. Positioning systems can assist people to determine the position of themselves or an object relative to a reference point in order to realize corresponding control and action. Among the various positioning systems, the most well-known is the Global Positioning System (GPS) developed by the United States, which consists of 24 "satellite clusters" that are spaced apart from each other and revolve around the earth. ground receivers to determine their o...
