摘　　要：蓝牙信标作为一种电池驱动的电子设备,电能耗尽导致信标无法工作或更换电池是亟待解决的关键问题。文章提出一种基于室内弱光采集的低功耗蓝牙信标设计方案。方案硬件上采用TI公司的能量采集芯片BQ25504和无线芯片CC2640,并开启MCU中断IO与能量采集芯片的电池状态端口连接,使得信标工作状态能在“广播—睡眠—掉电”之间自适应切换。文章最后给出了测试情况,在室内弱光条件下,能基本满足信标的工作,同时也验证了低能耗策略设计方案的正确性。As a battery-driven electronic device,Bluetooth beacon cannot work or battery is replaced due to the exhaustion of power is a key problem that needs to be solved urgently.This paper proposed a low-power Bluetooth beacon design scheme based on indoor weak light harvesting.The hardware of the solution uses TI's energy harvesting chip BQ25504 and wireless chip CC2640,and enables MCU to interrupt the connection between IO and battery status port of the energy harvesting chip,so that the beacon working state can be adaptively switched among“broadcast-sleep-shutdown”.At the end of the article,the test situation was given,which can basically meet the work of the beacon under the condition of indoor weak light,and can also verify the correctness of the low energy consumption strategy design scheme.
