<p>A multi-tag anti-collision method, reader and system for radio frequency identification. Wherein the method comprises: before the arrival of each time slot, the reader determines with a tag side the number of the tags which will be transmitted in the forthcoming time slot; when the reader determines the number of the tags is greater than 1, the reader determines that a multi-tag collision will occur in the forthcoming time slot, so it gives up receiving the data frame of the forthcoming time slot. The probability of the occurrence of the multi-tag collision can be effectively suppressed by this technical solution, and it is good for saving the communication traffic from the tags to the reader.</p> |
