基于ZigBee和Android手机的无线监控系统设计

针对智能家居、环境监测等对实时性的要求,提出了一种将近距离无线接入技术与Android、嵌入式技术相结合的无线监控系统设计方案。在高性能嵌入式平台上实现Wifi、ZigBee的接入,根据实际应用环境的需要,选用相应传感器实现对环境变量的数据采集,通过ZigBee无线组网方式进行数据收发。另外,将Android手机终端通过Wifi与嵌入式平台建立连接并实现数据传输,ZigBee终端接收无线传感器节点发出的数据,通过协调器将数据信息发送给嵌入式平台,数据经过处理以后反馈给智能手机终端,手机端根据接收到的数据进而输出相应的指令。文中介绍了系统的软件设计流程,对系统整体实验证明节点性能良好、通讯距离较为理想,该系统具有较好的通用性,能够满足实时性的要求。

Design of Wireless Monitoring System Best on Zigbee and Android phones

For the requirements of the smart home and environmental monitoring for real-time,a wireless monitoring system combines with Short-range wireless access technologies and Android,embedded technology is proposed.Achieve Wifi, ZigBee access on high-performance embedded platform,According to the actual application environment.Choose the appropriate sensor to achieve the environmental variables data collection.Send and receive data by ZigBee wireless networking.Other,The Android mobile terminals and embedded platforms establish a connection and data transmission with a Wifi network.ZigBee terminal can receive data sent from wireless sensor nodes, coordinator will send these data to the embedded platform.After processing feedback to the smartphone terminal.Mobile terminal corresponding output command according to the received data.This paper introduces the software design process,Nodes and Communication distance of the entire system proved good performance,The system has good versatility,Able to meet the requirements of real-time.
