自驾天气服务系统的设计与实现

自驾、客运和货运活动中,行驶路段天气状况已成为关系安全行驶的关键要素,使得个性化、精细化的自驾天气信息服务作为专业化气象服务的新需求越发强烈。为满足该需求,提出一套自驾天气服务系统模型。该系统模型以计算机Google Maps地图方式定制路线,手机客户端接收服务短信为目标完成设计。该设计以"数据→信息→知识→产品"的思路处理气象数据,获得的客观分析格点场气象服务信息作为气象服务基础;路线处理以Google Map API解析用户定制路线的JSON为基础,采用PrimeFaces的Decoder方法和分布函数过滤得到途经点路线的地理坐标集;最后对定制用户以短信方式提供途经点的气象信息服务。基于本模型开发的自驾天气服务系统已经投入试运行,开拓了新的短信气象服务业务方式。

Design and Implementation of Car Driving Weather Service System

Weather conditions have become a key element of driving safety, so the precision and individuation of meteorological information service for driving become the new urgent demand of operation meteorological service. To meet the demand, a system model of driving weather service is put forward. It is based on the customized route on the computer Google Maps and the short message service (SMS) received at mobile phone clients. The design is based on the data processing mode: data information knowledge products. The objective analysis of the gridded meteorological field information is used as the meteorological service foundation, and the route analysis is based on JSON, in which the user customized route is analyzed by means of Google Maps API. The PrimeFaces Decoder and the distribution function filtering methods are used to obtain the geographic coordinates of the route. The customized meteorological information service is provided via SMS to users. The car driving weather service system based on this model has been put into trial operation, which is a new attempt on SMS meteorological service.
