摘要： A method of establishing wireless communications between an interrogator and individual ones of multiple wireless identification devices, the method comprising utilizing a tree search method to establish communications without collision between the interrogator and individual ones of the multiple wireless identification devices, a search tree being defined for the tree search method, the tree having multiple levels representing subgroups of the multiple wireless identification devices, the number of devices in a subgroup in one level being half of the number of devices in the next higher level, the tree search method employing level skipping wherein at least one level of the tree is skipped. A communications system comprising an interrogator, and a plurality of wireless identification devices configured to communicate with the interrogator in a wireless fashion, the respective wireless identification devices having a unique identification number, the interrogator being configured to employ a tree search technique to determine the unique identification numbers of the different wireless identification devices so as to be able to establish communications between the interrogator and individual ones of the multiple wireless identification devices without collision by multiple wireless identification devices attempting to respond to the interrogator at the same time, wherein levels of the tree are occasionally skipped. RFID tags are managed by an interrogator. In one embodiment, the interrogator sends a first command indicating a first value and a first memory range, and a second command indicating second value and a second memory range. The first memory range differs from the second memory range by at least two bits. RFID tags compare the first and second values to corresponding values stored in the tags to determine if the tags are selected. Selected tags may respond to the interrogator with independently generated random numbers.
摘要翻译：一种在询问器和多个无线识别装置中的各个无线识别装置之间建立无线通信的方法，所述方法包括利用树形搜索方法建立通信而不会在询问器与多个无线识别装置中的各个无线识别装置之间发生冲突，搜索树被定义为树搜索方法，具有表示多个无线识别装置的子组的多个级别的树，一个级别中的子组中的设备的数量是下一较高级别中的设备数量的一半，采用跳过的树搜索方法，其中树中至少有一个级别被跳过。一种通信系统，包括询问器和多个无线识别设备，被配置为以无线方式与询问器进行通信，相应的无线识别设备具有唯一的标识号，询问器被配置为采用树形搜索技术来确定唯一的识别号码，以便能够在多个无线识别装置中的询问器和各个无线识别装置之间建立通信，而不会同时尝试响应询问器的多个无线识别装置的冲突，其中，偶尔跳过树。 RFID标签由询问器管理。在一个实施例中，询问器发送指示第一值和第一存储器范围的第一命令，以及指示第二值和第二存储器范围的第二命令。第一存储器范围与第二存储器范围不同至少两位。 RFID标签将第一和第二值与存储在标签中的相应值进行比较，以确定标签是否被选择。所选标签可以使用独立生成的随机数来响应询问器。

In one aspect, the method comprises transmitting a first command to select a group of RFID devices based at least in part on a first memory range beginning at a first bit location. The method further comprises transmitting a second command, successively following the first command, to select a subgroup of the group of RFID devices based at least in part on a second memory range beginning at a second bit location. The second bit location is shifted by two or more bits from the first bit location and receives a reply from at least one RFID device of the subgroup of RFID devices. The reply includes an identifier to uniquely identify the RFID device.
