基于CC2640的低功耗有源电子标签设计

Design of Low Power Active Electronic Tag Based on CC2640

有源电子标签是射频识别系统的重要组成部分,有效降低有源电子标签的功耗有利于进一步推进物联网技术的应用和发展。文章以TI公司的CC2640低功耗蓝牙芯片为核心器件,围绕着低功耗从硬件和软件改良两方面对有源电子标签进行设计,然后通过Android手机与电子标签进行通信,并测量通信过程中标签的运行功耗。结果表明该标签功耗低、通信稳定可靠,具有一定的应用价值。

Active electronic tags are critical for the radio frequency identification system.The effective reduction of power consumption of active electronic tags can further promote the application and development of the technology of Internet of Things.This paper designed an active electronic tags via hardware and software improvement aiming to the low power consumption based on TI’s CC2640 low-power Bluetooth chip as the core device.Then it was detected by communicating with the Android phone and electronic tags.Meanwhile,the running power of the tags during communication was measured.The results showed that the tag had low power consumption and reliable communication.Therefore,it has an certain application value.
