摘  要

本文详细介绍了基于百度云和NFC技术的会展导游系统的实现。

由于展会中存在大量未经筛选或提炼的信息，它们过分模糊了用户的焦点，导致用户的视线被噪音所遮掩，无法快捷地获取感兴趣的信息；并且传统的宣传媒介已无法满足用户获取更大的信息量、更多种类信息的需求。针对这种情况，本系统采用了手机移动客户端的方式，解决了用户浏览过程中关于信息获取的问题。

会展导游系统采用传统的C/S架构，使用了百度提供的各种云能力。在客户端上，通过富媒体展示，解决用户获取商品详尽信息、获取商品优惠券的需求；基于百度LBS云能力，解决用户获取周边商铺信息的需求；基于百度PCS云存储，解决用户对信息的持久化存储的需求；接入了流行的社交渠道，增加了用户浏览过程中的趣味性。

本文首先将对系统的产生背景做了介绍，并对现有媒介能力不足的现状做了分析；对百度提供的各种云能力，也做了详尽的说明。而后将会讲解系统的需求，与详尽的系统设计。最后，会预估系统对用户和对展商的收益，说明该系统的使用，不仅能为用户带来更友好的浏览体验、也能为展商带去更多的收益。

Abstract

In this page, an android mobile application system called ExGuide, which is based on Baidu Application Engine and near field communication technology is introduced here. The page will not only show the idea of the system, but also the design and implementation of which.

The idea comes from scene of exhibition. When you attend an exhibition, such as GuangZhou  Auto show , a motley variety of new cars or sexual Models will be displayed there You may be distracted by them, and can’t focus  your attention .You may not get what you wants immediately and fully. A direct mail can’t satisfy your requirement. So this android mobile application is design to deal with the situation mentioned above.

Client / Server architecture is applied on this system ,the Server is deployed on Baidu Application Engine .With the cloud ability of Baidu Application Engine, the Client will provides rich media of exhibition and  production for users, Baidu Location Based Service Cloud Service search restaurant near by venue for users, Baidu Personal Cloud Storage Service can save the rich media attachment on internet .On the other side, visitors should enjoy their trip by publishing what they see  in exhibition through Sina Weibo with ExGuide Client .

This page will introduce the background of the idea of ExGuide first ,then analyze the current situation of advertising system , point out whose weakness. In addition , Baidu  Application Engine will be introduced too. Finally , it will estimate its value that bring for exhibitor .
