摘要
提出一种新的基于nRF2401射频芯片和MSP430单片机的腕带式有源电子标签设计,包括硬件匹配电路设计、天线设计以及软件编程设计。该有源电子标签工作于2.45GHz,采用内设丰富且功能强大的无线收发模块nRF2401作为射频前端,外围电路极少,满足腕带式电子标签体积小的设计要求;采用低功耗高性能的MSP430单片机作为微控制器,数据处理速度快并且兼顾低功耗的要求。测试结果证明,该标签整体性能稳定,抗干扰能力强,工作距离可达70m。
A new design of wrist strap type active electronic tag based on nRF2401 RF chip and MSP430 MCU is proposed, including the design of hardware matching circuit, antenna design, and software programming. The active electronic tag works at 2.45 GHz, uses powerful wireless transceiver module nRF2401 as the radio front-end which has rich built-in resources and a few of peripheral circuits, and satisfies the small volume design requirement for the wrist strap type electronic tags; It uses MSP430 MCU with low power consumption and high performance as the micro controller, and features high speed data processing and low power consumption. The result shows that the tag has a stable performance, strong anti-interference capability and working distance is up to 70m.
