一种基于无线传感器网络的多生理参数监护系统

　　本文提出了一种基于无线传感网络的便携式生理参数测量系统。系统主要测量体温，脉搏和肌电信号三种生理参数，其传感器分别为DS18B20，PVDF压电薄膜和铜电极。无线传输模块选用ADI公司的ADF7020，本案中测量有效距离为150m。无线传感模块中的微处理器选用ADI生产的ADuC7026。上位机用VC++6.0编程。本系统可实现对病人的实时监护，并为每个病人提供了数据库，以记录其生理参数，为以后的治疗提供指导。本系统有一定的实用意义，可以用在敬老院或医护服务站等，便于医护人员对病人进行看护。

　　Design of Physiological Parameters Acquisition Based on Wireless Sensor Network System

　　A design of Physiological Parameters Acquisition Based on Wireless Sensor Network System，which can be used in senior citizen homes and nursing houses, is proposed in this paper. Temperature, pulse and myoelectricity are measured by DS18B20, PVDF films and copper electrodes respectively in the system. ADF7020 is chosen as the transmission and receiver, whose reliable communication distant is 150m. The micro controller in the node is ADuC7026. Program running on listener PC is written by C++. Every ward has his own database for diagnosis and therapy in the future.
