摘　　要： 针对目前特种监护设备接线复杂以及难以检查潜在健康危险的情况,提出了基于无线传感器网络的动态可佩戴生理监测平台,节点包括呼吸、心电、体位、体动、体温等多生理参数类型智能传感器。网关节点采用GPRS通信方式完成数据远程准确传送。所研制仿真系统,由GPS+GPRS模块XT5开发网关,节点采用Crossbow公司的MICA2和MICA2 DOT的等类型点状系列传感器。由志愿者佩戴后,将采取的生理和位置信息准确传到500公里外的监测点,终端计算机直观地查看到了受试者传送的信息。系统稳定地工作在2.4GHz频段,发射功率-5dB,数据速率最大40kbps。初步实验结果表明,系统原型可由特种监护者工作时佩戴于身体相应部位实时动态生理定位监测。系统通讯距离远、覆盖范围大,适合于核辐射环境下应用。 In view of special monitoring equipment wiring complexity and not checking potential health risks currently. Methods To propose monitoring platform of automatic wearing physiology based on wireless sensor network （WSN）, and nodes include multi-physiological parameter intelligent sensors such as respiration,ECG and position, movement, temperature of body. Network gateway completed the data remote transmission accurately by using GPRS communication mode. Researched simulation system developed network gateway by XT5 and nodes used punctate series sensors such as MICA2 and MICA2DOT of Crossbow Company. when experimenter wore the special monitoring the collected information of physiology and location was accurately transmitted to the monitoring point that was 500 kilometers away, thereafter terminal computer visually supervised the transmitted information of volunteers. The system stably operates at operating frequcency 2. 4GHz bands, transmit power-5dB, data rate 40Kbps or so. The principial result shows. The located monitoring of real-time dynamic physiology was carried out for the system prototype worn on the supervisor＇ s physical corresponding parts. The system is suitable for application in Nuclear Radiation Environment.
