The Design and Implementation of a Multiple Physiological Paramters Detection System Based on Android Platform

针对多生理参数的无创采集和移动传输需求,设计了基于Android平台的血氧饱和度、血压和心电等多生理参数检测系统.根据多生理参数的不同特性,通过定时中断模式,结合Android JNI和Linux驱动接口实现多生理参数无创硬件采集和无线实时传输,同时采用MVC开发框架,实现多生理参数的接收、显示、统计报表和用户管理等功能.为了减少数据冗余、提高数据融合效率,在多医学传感器形成的蓝牙散射网中,采用捕鱼策略优化算法进行收缩搜索和移动搜索.实验表明,该系统能有效实现多生理参数的无创采集、移动传输和智能处理,具有体积小、可扩展性强、融合效果优等特点,为家庭或社区监护和远程医疗创造了条件.

In view of the noninvasive acquisition and mobile designed a multiple physiological parameters detection system characteristics of multiple physiological parameters, the noninvasive transmission of physiological parameters, this paper based on Android platform. According to different hardware acquisition and wireless real-time transmission were implemented combing Android JNI and Linux driver by time interrupt mode. Meanwhile, the functions of receive, display, statistical reports and user management were realized in the MVC development framework. In order to reduce the data redundancy and improve the data fusion efficiency, the fishing strategy optimization algorithm was adopted to search in bluetooth scatter network. Experiments show that the system, which has the characteristics of small volume, strong extensibility and good fusion effect, can achieve the functions of noninvasive acquisition, mobile transmission and intelligent processing effectively. The system can prepare for monitoring family or community and telemedicine.
