基于蓝牙技术的推送系统的设计和实现
|
摘要
互联网和移动终端的普及推动着LBS向ILBS发展,而蓝牙与移动终端良好的契合使其成为室内定位技术的首选。分析了基于蓝牙技术的推送系统的原理,实现了以蓝牙节点、移动终端、服务器为三大模块的推送系统。实验结果表明,以蓝牙4.0设备发射信号、Bluetooth Adapter扫描搜索、Http URLConnection传输数据、JPush推送信息、Sae云平台移植组成的室内定位推送系统具有开发周期短、消息推送实时性强、稳定性好等优点。基于此构建的蓝牙技术的推送系统在室内定位方面具有很大的市场价值。
The popularity of the Internet and mobile terminal promotes the development of LBS to ILBS. A good combination with mobile terminal makes it the first choice of indoor positioning technology for Bluetooth. This paper analyses principle of push system based on Bluetooth technology,and realises the push system consisting of Bluetooth node,mobile terminal and server. The experimental results shows that indoor positioning push system consisting of lanching signal with Bluetooth 4. 0 equipment,scanning signal with Bluetooth Adapter,transmiting data with Http URLConnection,pushing message with JPush and deploying on Sae Cloud platforms has the advantages of short development cycle,high real-time of pushing message,good stability and so on. Push system based on this design pattern has great market value in indoor positioning.
