基于移动互联网的交通气象服务系统设计与应用

Design and Application of Traffic Meteorological Service System Based on Mobile Internet

设计并实现了基于移动互联网的交通气象服务系统。通过对用户定位信息与天气现象、能见度、温度、降水、风力等精细化格点数据进行融合,提供了一系列基于位置的创新性交通气象服务:道路前方高影响天气路段语音提醒及气象信息自动化语言表达、基于WebGIS服务的交通气象服务信息展示和基于精细化格点预报数据的智能导航。与传统网页单向式的信息交互方式不同,交通气象服务系统绝大部分数据存储及处理工作在服务端完成,通过Web服务实现了与客户端的双向信息传递,向用户提供精准的基于位置的信息推送。本系统已经在浙江省气象局智慧气象手机客户端中作为一个独立模块实际应用。

A traffic meteorological service system based on mobile internet is designed.Through combining a series of refined gridded data,the system provides a series of personalized traffic meteorological services based on locations,such as voice navigation services for high-impact weather,meteorological knowledge extraction,integrated Web publishing based on WebGIS,and intelligent navigation based on the refined gridded data.To ensure high bearing capacity and rapid response characteristics,the refined gridded data are transferred in the binary model,and the tiled map resources are generated in the distributed computing environment.The whole process of data processing is managed by the memory management mechanism of Memcached.This system has already been applied as an independent module in the SmartWeather mobile client designed by the Zhejiang Provincial Meteorological Service.
