一种无源室内定位节点装置及相应的室内定位系统
摘要：
本发明公开了一种无源室内定位节点装置以及相应的室内定位系统。本发明中的无源室内定位节点装置通过天线阵列收集室内环境中的电磁波信号并输入给能量收集电路，能量收集电路将该电磁波信号转换成低压电能存储在本地能量存储器中供超低功耗微处理和天线控制器使用，超低功耗微处理通过控制天线控制器的开通和断开，将本地预存的数据通过天线控制器控制天线阵列发射出去，并且采用环境电磁波反向散射通信技术，能够极大降低发射编码信号时的功耗。本发明实施例实现了无源室内定位节点装置，既能通过收集环境中的电磁波信号并转换成自身所需电能，又能极大降低定室内位节点在发射信号时的能量消耗。从而极大地提升室内定位节点布置的方便性。
摘要（英）：

The invention discloses a passive indoor positioning node device and a corresponding indoor positioning system. The passive indoor positioning node device collects an electromagnetic wave signal in anindoor environment through an antenna array and inputs the electromagnetic wave signal to an energy collection circuit; the energy collection circuit converts the electromagnetic wave signal into low-voltage electric energy and stores the low-voltage electric energy in a local energy accumulator for ultralow power consumption micro-processing and an antenna controller; the ultralow power consumption micro-processing controls the antenna controller to be turned on and off, the antenna controller controls the antenna array to emit local pre-stored data; and in addition, an environmental electromagnetic wave backscatter communication technology can be adopted to greatly lower power consumption when a coding signal is emitted. By use of the embodiment of the invention, the passive indoor positioning node device is realized, the electromagnetic wave signal in the environment can be collected and converted into own required electric energy, energy consumption when the indoor positioning node emits a signal can be greatly lowered, and therefore, indoor positioning node arrangement convenience is greatly improved.
