The composition of the radio frequency identification system generally includes at least the following two parts: transponder and RFID electronic tag reader. Transponder: RFID electronic tags are a kind of transponder, the English name is Tag or Smart Labels. RFID electronic tags are mainly composed of coils and chips, each RFID electronic tag has a agreed format of electronic coding, RFID electronic tags attached to the object to identify the target object. RFID electronic tag Reader: the English name is Reader, RFID electronic tag reader can read and identify the electronic data stored in the RFID electronic tag without contact, so as to achieve the purpose of automatic identification of objects, and can further transmit the data to the meter and network to achieve the collection, processing and remote transmission of object information and other management functions. The working principle of the radio frequency identification system: After the Tag enters the magnetic field, it receives the radio frequency signal sent by the RFID electronic Tag reader. The RFID electronic Tag transmits the information stored in the chip by virtue of the energy obtained by inductive current (Passive Tag), or actively sends a certain frequency signal (Active Tag). RFID electronic tag reader reads the information and decodes it, and sends it to the central information system for data processing.
From the whole project, it is composed of software system and hardware system
The hardware system is composed of the following parts: RFID reader, antenna, electronic tag, host computer, gateway, server
