摘要
针对当前宠物频繁丢失的问题,本文设计并实现了基于MQTT协议的智能宠物追踪系统.系统的功能实现主要依托于MQTT服务器、Web服务器和基于Android平台开发的应用程序.嵌入式设备采用集成MTK2503芯片组的WZ-203CS开发板,依靠开发板内嵌的物联网卡,通过MQTT消息传输协议,将位置信息传送至Android应用程序.应用程序通过集成高德地图导航功能,利用已接收的位置信息,提供语音导航、路径规划等功能.基于该架构设计的追踪系统,并不局限于宠物追踪,通过系统预留的接口可扩展其他相关功能,实现可用性的同时具有较强的可扩展性.
With the frequent loss of pets,a pet-tracking system based on Message Queuing Telemetry Transport(MQTT)protocol is designed.The function realization of the system mainly relies on MQTT server,Web server and application program based on Android platform.The embedded device is made from a WZ-203CS demo board which integrates the MTK2503 chipset.With the help of the embedded IoT card,the device can transfer information about its location to Android mobile device under the MQTT protocol.Due to integrating the Amap navigation system,the application provides voice navigation,path planning,and other functions by processing the received information about location.Thanks to the basic structure,the system’s function is not merely pet-tracking,but also has reserved interfaces for future uses,making the system more practical and has strong extensible at the same time.
