基于MSP430及安卓系统的老年人生理信息监护系统

The Monitoring System for The Physiological Information of The Elderly Based on The msp430 SCM and Android System

目的：随着老龄化的不断加剧，老年人的监护需求量也在不断的增加，为了解决相应的老年人监护问题，介绍了一种基于MSP430单片机和安卓系统结合的老年人生理信息采集监护系统的工作原理。方法：以MSP430为核心，配以血氧、体温等传感器模块对老年人生理信息进行采集，利用传感器技术与嵌入式技术相结合。设计了生理信息采集终端。设计中采用了跌倒检测，在老年人出现跌倒时，能够及时通知监护人员，防止出现救治不及时的情况，同时还利用蓝牙通信，将采集的信息上传到基于Android系统的智能手机终端。利用Android系统上传数据到服务器，为老年人建立生理监护系统。结果：对设计进行了实验测试．经试验表明系统能够正常的进行数据采集，体温测量数据误差在±0．3℃，血氧饱和度的测量在正常范围95％-98％之间，跌倒检测很准确的检测到了跌倒状况，满足测试的标准，达到了设计的预期效果。结论：该系统能够很好的实现老年人的生理信息监护．对老年人的血氧、体温进行了很好的监测．在老年人出现跌倒时能够及时的进行报警，得到救治，具有良好的扩展性和广泛的应用前景。

Objective： With the growing aging, elderly care demand is constantly increasing. In order to solve the problem of ap- propriate elderly care, the working principle of the monitoring system for the physiological information based on msp430 SCM and Android system is detailedly introduced in this paper. Methods： With the msp430 as the core, the collection terminal is e- quipped with the sensor modules, such as temperature sensor, blood oxygen sensor, and so on. Using sensor technology and em- bedded technology, physiological information collection terminal is designed in this paper. A fall detection is used in the design, when old people fall, the system can inform the custodial staff in time to prevent a situation that the treatment is not timely, The collection terminal uploads the collected information to the smart phone with android system by Bluetooth. Establish the physio- logical monitoring system for elderly by uploading data to the server through the android system. Results： The system is tested. Tests show that the system can accurately collect data. The range of temperature error is from -0.3~C to ＋0.3~C, the measure- ment of oxygen saturation is in the normal range which is between 95% and 98%, fall detection accurately detects the fall situa- tion. The system meets the testing standards, and achieves the desired effect. Conclusions： The system can monitor the physio- logical information of the elderly, for example the oxygen saturation and body temperature. The system can alarm when old people fall down, and make that the elder can be treated in time. The system has good scalability and broad application prospects.
