提出了一种基于短距离无线通信技术的传感器网络监测设计方案,设计中采用了MSP430系列微处理器进行信号调节和数值处理,通过集成电源模块、输入模块、无线传输模块和LCD显示模块形成患者生命体征监护传感器的终端节点;在阐述血液净化原理的基础上进行系统的硬件和软件设计,系统分析了各传感器节点与血液净化中心节点之间的实时网络数据传输,解决了血液净化中运行状态的过程控制、患者实时体征监测和实时参数调节等系列问题,最后通过实验仿真测试达到了个性化治疗和安全监控的目的。

A sensor network monitoring scheme based on short distance wireless communication technology is proposed in this paper. The MSP430 series microprocessor is used to conduct the signal conditioning and numerical processing in the design. The terminal node of patients signs of life monitoring sensor is formed by integrating the power module, input module, wireless transmission module and LCD display module. The hardware and software of the system are designed based on the principle of blood purification. The real-time network data transmission between the nodes of sensors and central node of blood purification equipment is systematically analyzed. Series problems such as the process control of blood purification in running status, real-time signs monitoring of patients and real-time parameters adjustment have been solved. And finally the individualized treatment and safe monitoring are achieved through the experimental simulation test.
