| 摘 要： | 为了适应室内人员追踪定位系统对节点体积、供电、定位精度等的要求,提出了一种以ATmega128L单片机和NA5TR1无线收发芯片为核心的无线定位节点的硬件电路设计方案。ATmega128L单片机具有低功耗的休眠模式,能有效降低节点功耗,NA5TR1无线收发芯片采用线性调频扩频技术进行测距,经实验证明,该测距方法能有效地提高测距精度,从而提高定位的精度。

| Abstract: | In order to meet the requirements of node size,power supply,positioning accuracy of indoor personnel positioning system,a hardware circuit design scheme for wireless location node is presented,which takes microcontroller ATmega128L and wireless transceiver chip NA5TR1 as its core.ATmega128L microcontroller has a low-power dormant mode,which can effectively reduce node power consumption.NA5TR1 wireless transceiving chip measures the distance by using CSS technology.The experiments show that the ranging method can effectively improve the ranging accuracy,thereby the positioning accuracy is enhanced. |
