中文摘要：
本文设计了一种基于低功耗蓝牙技术结合多传感器协同判断的穿戴式跌倒检测系统，系统由控制芯片、传感器以及对应的硬件与软件构成。通过实验室环境下的跌倒实验测试，表明该系统能有效区分跌倒与日常行为活动。通过系统功耗测试，结果显示跌倒检测系统在待机状态和工作状态的总功耗分别为35μW和41μW，采用纽扣电池CR2032供电的情况下即能满足长期使用的要求。
英文摘要：
A wearable fall detection system with multi-sensor cooperation which based on the bluetoothlow energy is designed. This system consists of control chip, sensor and corresponding hardware andsoftware. Through fall experimental tests in laboratory environment, it’s shown that the fall detectionsystem can distinguish between falls and activities of daily living effectively. The power consumptionmeasurement of the system indicates that the total power consumption of the ready mode and operativemode are 35 μW and 41 μW respectively. And it can realize long-term use with the button batteryCR2032 power supply.
