基于北斗的手机订餐系统优化研究

针对目前市场上主流手机订餐应用系统，文中开发了一款基于北斗导航的订餐系统，对现有订餐应用系统进行优化。系统通过在餐车上安装带有GPRS和BDS的定位模块，实现定位和数据传输，在手机上安装Android客户端进行显示，服务器端进行处理数据。通过GPRS将北斗的定位信息发送到服务器，服务器对数据进行处理实现实时定位、领餐短信提醒和剩余时间显示等功能。然后服务器将数据处理的结果发送到客户端进行显示，实现路径规划、送餐导航。同时该系统使用A*算法进行路径规划，使系统更加快速高效。

Based on Beidou Navigation System Optimization Meal Ordering Applications

Regarding to the popular meal ordering Apps in the market, we have developed a meal ordering system aiming at optimizing the current ordering platform through the Beidou Navigation Satellite System(BDS). The system realizes localization and achieves data transmission through installing GPRS and BDS orientation modules with messages shown on the Android client side in phones and data processing of the server side. In this system, route planning and navigation can be more easily to achieve through a series of procedures, transmitting positioning information of the Beidou Navigation Satellite System to server through GPRS, implementing functions of real-time positioning, SMS reminders and rest-time recording through data processing, as well as showing results on the client side. Apart from this, what makes the system faster and more efficient is the use of A* arithmetic to plan paths.
