    • The present invention relates to a collision prevention method for a RFID system and a RFID system to minimize the collision of response signals by using sector antennas and controlling the power. The present invention comprises the steps of: separating plural tags in a space by setting up plural number of sector antennas; setting up the output stages of the power of each sector antenna to be increased in plural sequential stages; and reading a tag belonging to the output range by selecting a first sector antenna and transmitting minimum power among the set up stages. The present invention considerably reduce the collision probability of response signals of tags by dividing the tags in a space when a reader reads or writes tag information. The present invention also minimizes the time consumed to read/write tags and improves the communication distance and capacity.
    • 本发明涉及一种用于RFID系统和RFID系统的防碰撞方法,以通过使用扇区天线来最小化响应信号的冲突并控制功率。 本发明包括以下步骤:通过设置多个扇区天线来分离空间中的多个标签; 建立多个连续阶段增加每个扇区天线的功率的输出级; 以及通过选择第一扇区天线并在所述建立阶段之间传送最小功率来读取属于所述输出范围的标签。 当读取器读取或写入标签信息时,本发明通过在空间中划分标签来大大降低标签的响应信号的冲突概率。 本发明还将读取/写入标签的时间最小化,并且提高通信距离和容量。
