BLE Mesh组网的可穿戴设备低功耗研究

Research on Wearable Device Low-power Consumption Based on BLE Mesh Networking

针对目前可穿戴式设备功耗高的问题,本文进行了基于BLE Mesh组网的可穿戴设备低功耗的研究。以可穿戴单兵冲击波损伤测评系统为例,设计了一款基于Mesh组网的单兵冲击波损伤测评系统,该系统在原有系统的基础上增加了一个蓝牙组网。由于可穿戴设备采用纽扣电池供电,为了保证该系统的功耗不能有大幅度的增加,本文采用泛洪算法和低功耗模式方法来降低功耗。通过与其他降低功耗的方法进行对比分析,验证了该算法的有效性。

In view of the current problem of high power consumption of wearable devices,the low-power consumption of wearable devices based on BLE Mesh networking is proposed.Taking the wearable shockwave damage assessment system for individual soldier as an example,a shockwave damage assessment system for individual soldier based on Mesh network is designed,which added a Bluetooth network on the basis of the original system.Since the wearable devices are powered by button batteries,in order to ensure that the power consumption of the system cannot be greatly increased,flooding algorithm and low-power mode are adopted to reduce the power consumption.Compared with other methods to reduce power consumption,it is verified that the algorithm can effectively reduce power consumption.
