摘要
为了实现多生理参数远程监测系统数据感知前端可分离式自由穿戴、可近程无线组网及低功耗等要求,依据无线体域网(WBAN),利用MSP430与蓝牙4.0构成了包含心电、血压、血氧饱和度等多生理参数的分离式无线传感单元,设计了基于ARM9的多参数近程汇聚与远程无线传输终端。各传感单元通过蓝牙4.0和采集终端实现自由组网,解决了终端机与各分离式无线传感单元间的多生理参数时间同步、可靠数据通信及低功耗设计等问题,为人体多生理参数的穿戴式无线传感、无导联线数据采集和远程无线传输提供了一种前端数据感知与采集模式。
To meet the needs of separate wearable sensing modules,wireless networking in short-range and low power consump-tion for the remote multiple physiological parameters monitoring system,a novel front-end data sensing and collecting based on wireless body area network （WBAN）was proposed.Wireless sensor units were designed using MSP430 processor and Bluetooth wireless communication module to detect multiple physiological parameters physiological parameters such as ECG,blood pressure and oxygen saturation.Mobile monitoring terminal and short-range communication protocol of Bluetooth 4. 0 were used to realize the free networking between individual sensors unit and mobile acquisition terminal.Furthermore,some problems were solved such as time synchronization of multiple physiological parameters processor,reliable data communication,and low power con-sumption mechanism between terminal and each separable wireless sensor unit.The system provided a new front-end data sen-sing,detecting and transmitting pattern for wearable WBAN user.
