METHOD FOR CONTROLLING REAL-TIME TIME DIVISION COMMUNICATION BETWEEN RFID READERS AT CONGESTED ENVIRONMENT

摘要

A real-time time-sharing communications control method of an RFID reader under congestion environment is provided to prevent the collision between readers by compulsorily controlling the communication timing of each RFID reader at real time. A plurality of RFID readers in connection with a control program is performed by the control program. A time slot at a time communicating with an RFID tag about each RFID reader is set and stored in order not to be overlapped. A time order communicating with an RFID tag about each RFID reader is set and stored in order not to be overlapped. A communication command is delivered to be fit about each RFID reader(S28). The control program is performed according to each RFID reader and TCP/IP protocol.
