A design method of two-dimensional mobile node of digital shelves based on RFID

文章提出了一种读取数字货架上货品电子标签信息的二维移动节点的设计方法。采用双导轨垂直安装、单片机控制、双电机驱动的方法控制节点的二维运动,利用RFID(radio frequency identification)读卡器实现货品信息的读取和更新,以及ZigBee无线通信实现信息的无线传输。重点介绍了复杂情况下的基于A*算法的节点路径规划算法,进一步提高了信息读取效率。

A design method of two-dimensional mobile node used on digital shelves for reading electronic labels on goods is put forward.The two-dimensional mobile node is mounted on double rails vertically,and it is driven by double motors which are controlled by a microcontroller unit.And radio frequency identification（RFID）reader is used to realize the reading and updating of the information of goods,and ZigBee is used to achieve wireless communication.And a path planning algorithm based on A＊algorithm under complex conditions is expounded to further improve the efficiency of information reading.
