摘要
设计了一种基于输出型最大功率点跟踪控制和蓝牙低功耗传输技术的可穿戴传感器节点,并实现了自主式无线体域网。可穿戴传感器节点在一块柔性太阳能面板上集成了加速度计、温度传感器和插入式光电容积描记传感器;为了从柔性太阳能面板中提取最大能量,提出输出型最大功率点跟踪,以控制太阳能采集器最大化输出功率;通过一个商用BLE模块将传感器节点的所有数据发送到智能手机应用程序中。实验结果表明,在为传感器节点设定合适的"唤醒-睡眠"模式,传感器节点可通过太阳能采集器供电实现全天24小时运行。与其他方法相比,具有更低的能耗和更多的功能。
A wearable sensor node using output maximum power point tracking control technology and Bluetooth low energy transmission technology was designed, and an autonomous wireless body area network was implemented. Firstly, the wearable sensor node integrated accelerometer, temperature sensor and plug-in photo plethysmo graph sensor on a flexible solar panel;In order to extract maximum energy from flexible solar panel, output MPPT was proposed to control solar collector to maximize output power;Finally, a commercial BLE module was used. All data of sensor nodes were sent to smart cellphone applications. The experimental results show that the sensor nodes can operate 24 hours a day with solar collector power supply under the condition of setting appropriate “wake-up-sleep” mode for the sensor nodes. Compared with other methods, the method has lower energy consumption and more functions.
