基于Netty的城市交通信息快速告知终端设计与实现

Design and Implementation of Terminal for Urban Traffic Information Quickly Informed Based on Netty

结合道路出行者对交通事件信息的需求,基于Android操作系统,采用Netty通信框架与JSON数据封装格式,设计了城市交通信息快速告知终端,实现了与城市交通信息推送集成管理平台间的数据交互;应用百度语音合成、百度地图开发和SQLite数据库操作等相关技术,整体上实现了交通事件信息的采集与上传、信息接收与处理、信息播报以及车主互通等功能。测试结果表明:终端性能可靠,能有效完成数据处理和实时交通事件信息展示。

According to the needs of road traveler for information on traffic incidents, based on Android, the terminal of urban traffic information quickly informed was designed by using Netty communication framework and JSON which is a format of data encapsulation. The data interaction in urban traffic information push integrated management platform was realized. Baidu TTS（Text To Speech）, Baidumap development, SQLite database operations and other related technologies were applied to achievethe receiving, processing, collection, uploading and broadcast information of traffic incidents and communication between drivers. The result of the tests shows that the terminal has reliable performance. It can complete data processing effectively and display real-time traffic incidents information.
