Than the number of existing RFID (Radio Frequency IDentification) systems, multiple RFID readers are installed to the lack of a specified channel leader to frequent this does not work effectively the situation as installed, the specified number of particularly that operates leader channel in space it is a lot of dense reader environment (dense reader environment) the reader protocol used to efficiently use the specified channel is essential to break the reader down the tag identification efficiency and recognition speed of the RFID system when the tag recognition operation reader collision (reader collision) You may experience problems. In the present invention, by occupying the channel in the trigger reader is empty through the channel scan and transmit synchronization pulses, and so as to form a hierarchical structure among the reader, the upper layer reader is of a lower layer through a communication section between the reader being the amount of time the request from the reader by giving it the time to double the operation, each of the reader to be able to use the occupied channels in sequence. Because of this, in the present invention can minimize the reader collision while efficiently use the available channel in the dense reader environment.
