Abstract: PURPOSE: An active wireless frequency recognition tag and a location searching method of the same are provided to transmit the sub blink ID information corresponding to the sequence of the sub blink with the sub blink when an active tag transmits the sub blink in a RTLS(Real Time Locating Systems) system, thereby easily performing location calculation by serial arrangement of sub blinks without comparing arrival time information of the sub blink one by one in location processor engine. CONSTITUTION: A location processor engine stores ID information of tag which sent a blink signal, sub blink ID information, and arrival time information of each sub blink(S402). The engine again groups information grouped per tag ID according to each sub blink ID(S404). If the arranged sub blinks are more than three, the engine calculates the location of active tag through the arrival time information of the sub blinks(S406,S408).

Abstract translation: 目的：当有源标签在RTLS中发送子眨眼时，提供主动的无线频率识别标签和位置搜索方法来发送与子眨眼序列相对应的子眨眼ID信息与子眨眼（实时 时间定位系统）系统，从而通过串行排列子闪烁轻松执行位置计算，而不会在位置处理器引擎中逐个比较子闪烁的到达时间信息。 构成：位置处理引擎存储发送眨眼信号的标签的ID信息，子眨眼ID信息和每个子眨眼的到达时间信息（S402）。 引擎再次根据每个子眨眼ID对每个标签ID分组信息（S404）。 如果配置的子闪烁超过三次，则发动机通过子闪烁的到达时间信息来计算活动标签的位置（S406，S408）。
