【摘要】：健康,是亘古以来人类除了生存以外所考虑的问题之一。由于古代的医疗条件落后,所以由疾病引发的死亡是造成人口减少的主要原因,因而如何预防疾病也就逐渐被人类所重视。随着人们的物质水平逐渐提高,人们不仅仅关注精神方面的需求,更对自己的健康状态要求逐渐提升。由于我国的人口基本国情表现为低出生率与高老龄化的两极分化以及亚健康人群数量增长的趋势,所以对健康医疗监测系统的研究设计也是社会需求的结果。 本文重点介绍了一种基于无线多参数人体健康监护系统中的血压监测系统的设计。该监测系统主要包括信息采集模块、数据处理模块和ZigBee传输模块,信息采集模块完成人体生理参数血压的采集并在数据处理模块部分进行计算,采用ZigBee传输模式将信号数据送至数据中心模块,最后在中心模块完成与其他生理参数信号的融合处理并通过局域网网络上传至医疗监控中心方便专家查阅诊断。本论文重点介绍血压信号采集模块的原理、电路硬件设计及其软件设计。采集模块的硬件电路包含外接电路、气动电路以及驱动电路,这部分电路完成血压的前期采集,通过压力传感器转换为电信号,并通过信号提取电路进行滤波和运放送至控制芯片的A/D转换得到相应的静压信号和脉搏信号,最后通过软件计算最终得出我们需要的平均压、收缩压和舒张压以及脉搏值。 系统采用IT公司的MSP430FG149低功耗芯片,设计了无线血压监护系统,使其具有功耗低、体积小、存储容量大和处理速度高等特点,采集模块与ZigBee发射接收模块相连,可以实现血压生理信号的监测和无线传输,使得人体健康状况无线血压监测到实时监控成为一种可能。
[Abstract]:Health has been one of the problems that human beings have considered in addition to survival since ancient times. Because of the backward medical conditions in ancient times, the death caused by disease is the main cause of population decline, so how to prevent disease is gradually paid attention to by human beings. With the improvement of people's material level, people pay more attention not only to their spiritual needs, but also to their state of health. Because of the polarization of low birth rate and high aging population and the increasing trend of the number of sub-healthy population in China, the research and design of health medical monitoring system is also the result of social demand. This paper focuses on the design of a blood pressure monitoring system based on wireless multi-parameter human health monitoring system. The monitoring system mainly includes information acquisition module, data processing module and ZigBee transmission module. The information acquisition module completes the blood pressure collection of human physiological parameters and calculates in the data processing module. The signal data is sent to the data center module by ZigBee transmission mode. Finally, the signal fusion with other physiological parameters is completed in the center module and uploaded to the medical monitoring center through the LAN network to facilitate experts to consult the diagnosis. This paper focuses on the principle of blood pressure signal acquisition module, circuit hardware design and software design. The hardware circuit of the acquisition module includes external circuit, pneumatic circuit and drive circuit. The signal extraction circuit is used to filter and transport to the control chip A / D conversion to obtain the corresponding static pressure signal and pulse signal. Finally, the average pressure, systolic pressure, diastolic pressure and pulse value we need are obtained by software calculation. The system adopts MSP430FG149 low power chip of IT company, designs wireless blood pressure monitoring system, which has the characteristics of low power consumption, small volume, large storage capacity and high processing speed. The acquisition module is connected with the ZigBee transmitting and receiving module. It can realize the monitoring and wireless transmission of blood pressure physiological signals, which makes it possible to monitor human health status by wireless blood pressure monitoring in real time.
