US08742931B2 Electronic seal with multiple means of identification and method based on electronic seal for inspecting goods 有权
电子密封具有多种识别方法和基于电子密封的方法进行货物检验

Electronic seal with multiple means of identification and method based on electronic seal for inspecting goods
Abstract:
An electronic seal includes a radio frequency identification apparatus, an antenna assembly and an impedance matching circuit. The radio frequency identification apparatus includes at least two radio frequency identification units each for providing a specific code for identification. The antenna assembly is electrically connected to the radio frequency identification units. The antenna assembly is used to receive an electromagnetic signal for identification to excite the radio frequency identification units to transmit the specific codes through the antenna assembly. The impedance matching circuit is provided between the radio frequency identification units and the antenna assembly for adjusting the impedance matching of the radio frequency identification units to the antenna assembly, thus adjusting excitation powers and feedback powers of the specific codes from the radio frequency identification units through the antenna assembly.
Abstract(Chinese):

电子密封件包括射频识别装置，天线组件和阻抗匹配电路。 射频识别装置包括至少两个用于提供用于识别的特定码的射频识别单元。 天线组件电连接到射频识别单元。 天线组件用于接收用于识别的电磁信号，以激励射频识别单元通过天线组件发送特定代码。 阻抗匹配电路设置在射频识别单元和天线组件之间，用于调整射频识别单元与天线组件的阻抗匹配，从而从射频识别单元调整特定码的激励功率和反馈功率， 天线组件。
