Design and Implementation of Domestic Mobile Monitoring System  Based on ZigBee and Android

摘要:

为解决传统家用监护系统成本高、移动性差、布线困难等问题,设计并实现了一种基于ZigBee和Android技术的家用移动监护系统;系统采用分层的体系结构,第一层为检测终端,以STM32微处理器为核心,包含多个生理信息采集节点；第二层为家庭网关,包括ZigBee主节点和计算机服务器,通过ZigBee无线组网技术完成服务器与检测终端的网络通信；第三层为Android移动平台,通过外部网络访问服务器,提供远程交互平台;该系统应用于老年人的家庭健康监护,对体温和血压两项重要生理指标进行测量;实验表明,该系统通信质量良好,能够实现生理信号的采集、传输和波形显示,以及血压值、体温值的分析和高危报警,满足了家用移动监护的要求。

Abstract:

To solve the problems in traditional domestic surveillance system including high cost, poor mobility, difficulty wiring and so on, a domestic mobile surveillance system based on ZigBee and Android was designed and realized. The system was with a layered architecture. The first layer was detection terminal with STM32 microprocessor core, including multiple physiological data collection nodes. The second layer was home gateway, including main node on ZigBee and the server computer. The gateway realized network communication between the server and detection terminal by wireless network technology of ZigBee. The third layer was Android mobile platform, which accessed the server with external network to provide an platform for remote interaction. This system is used in domestic health monitoring to the elderly. Two important physiological indexes, blood pressure and body temperature, are measured. The experiments show that this system has good communication quality, can achieve the collection, transmission and waveform display of physiological data, also the analysis and danger warning of blood pressure and body temperature, which meets the requirements of the domestic mobile monitoring.
