现有的多生理参数监测系统，其各个传感与采集单元在物理层和数据链路层采用一体机集成模式，不利于多生理参数的穿戴式传感与无线组网，为此提出了基于无线体域网(WBAN)的分离式多生理参数无线传感、采集与前端组网新方法.主要研究了以 MSP430为控制核心的低功耗多生理参数传感节点、基于智能手机终端与蓝牙2.0的前端 WBAN组网模型、多生理参数远程无线传输网关以及手机终端软件的设计与实现.测试结果表明：基于 WBAN的无线传感与组网新方法能够实现多生理参数的无线采集、组网与数据传输，避免了传统多生理参数监测存在的导联线过多、使用不方便、信号信噪比低、用户活动受限等问题.该方法以“穿戴式无线感知+手机远程无线传输”模式，为多生理参数无线监测走向家庭健康监护、为亚健康人群的疾病预警提供了技术支撑.

Many problems exist in traditional multiple physiological parameters monitoring system,such as difficulty to achieve wearable sensing and wireless networking caused by the “multi-parameter integrated”design mode of various sensing and acquisition units in the physical layer and the data link layer.In this paper,a novel solution based on wireless body area networks (WBAN)has been proposed to meet the needs of multiple physiological parameters sensing,acquisition and networking in wearable and independ-ent model.The front-end subsystem is composed of wireless physiological parameter sensing nodes based on MSP430,WBAN networking structure with smartphone as control center of multiple wireless gateway for remote physiological parameters transmission and development of specific embedded software for cell phone.The experiment results show that,by the WBAN-based wireless networking,some problems of classical monitoring system,such as too many lead wires,inconvenient option,low SNR of parameters, and limit range of movement,can be avoided.As an implementation of data collection front-end with“wearable WBAN wireless sensing and mobile wireless transmission”mode,it can provide technical sup-port for convenient home health care and facilitate disease warning services for sub-health population effi-ciently.
