| 摘 要： | 一种基于Atmel公司的ATMEGA48低功耗单片机和nRF2401低功耗射频芯片的有源电子标签,从硬件上作了优化设计,选择本身功耗较小的器件,以减低对电池的消耗。在软件层面上,对休眠算法进行了优化设计,最大限度让标签工作在休眠状态,同时在需要时又能及时唤醒。通过对程序算法改进设计,达到标签最低功耗待机休眠,以保证标签在特定的工作环境下长期工作,而不需要经常更换电池。

| Abstract: | Based on the low power consumed single chip of ATMEGA48 and the radio frequency chip of nRF2401,This paper chooses the lower power consumed chip and optimizes the hardware design to reduce battery consumption.In software,the sleep algorithm is optimized to make the active tags sleeping farthest,while it can be waked up immediately.it increases the lowest power consumption standby sleep time of the tags to ensure the tags working longly in a special environment without replacing the battery frequently. |
