标准摘要
[中文适用范围]： ISO/IEC 18000 的本部分定义了用于物品管理应用的射频识别 (RFID) 设备的空中接口，该设备工作在 860 MHz 至 960 MHz 的工业、科学和医疗 (ISM) 频段。它为 RFID 设备提供了通用技术规范，可供制定 RFID 应用标准的 ISO 委员会使用。ISO/IEC 18000 的本部分旨在实现兼容性，并鼓励产品在国际市场上不断增长的 RFID 市场中实现互操作性。它定义了前向和反向链路参数，这些参数用于技术属性，包括但不限于工作频率、工作信道精度、占用信道带宽、最大有效全向辐射功率 (EIRP)、杂散发射、调制、占空比、数据编码、比特率、比特率精度、比特传输顺序，以及（如适用）工作信道、跳频速率、跳频序列、扩频序列和码片速率。它进一步定义了空中接口中使用的通信协议。 [外文原描述]： ISO/IEC 18000-62:2012 defines the air interface for radio frequency identification (RFID) devices operating in the 860 MHz to 960 MHz Industrial, Scientific, and Medical (ISM) band used in item management applications. It provides a common technical specification for RFID devices that can be used by ISO committees developing RFID application standards. It is intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market in the international marketplace. It defines the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum effective isotropic radiated power (EIRP), spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate, hop sequence, spreading sequence, and chip rate. It further defines the communications protocol used in the air interface. ISO/IEC 18000-62:2012 specifies the physical and logical requirements for a passive-backscatter, Interrogator-Talks-First (ITF) systems. The system comprises Interrogators, also known as readers, and tags, also known as labels. An Interrogator receives information from a tag by transmitting a continuous-wave (CW) RF signal to the tag; the tag responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. The system is ITF, meaning that a tag modulates its antenna reflection coefficient with an information signal only after being directed to do so by an Interrogator. ISO/IEC 18000-62:2012 contains Type B. Type B uses Manchester in the forward link and an adaptive binary-tree collision-arbitration algorithm. ISO/IEC 18000-62:2012 specifies physical interactions (the signalling layer of the communication link) between Interrogators and tags, Interrogator and tag operating procedures and commands, the collision arbitration scheme used to identify a specific tag in a multiple-tag environment.
