In order to improve the rate of recognition multi-tags from existing RFID system,reduce data redundancy and collision frequency.An uninterrupted querying algorithm based on the existing dynamic binary search algorithm is proposed.Firstly this algorithm determined collision position by Manchester encoding,then forward search while the stack is formed further search command.Through optimize the search and response command.Finally backtracking stack to identify the labels one by one;Experimental results show that the algorithm reduces the amount of data transfer and search iterations to be significantly better than existing classical binary anti-collision algorithms.
