基于云计算的外勤通系统设计与实现技术研究

摘要

The problem often exists between field staff,business travelers and business decision makers in difficult real-time communica-tion. To reduce enterprises management cost and promote management efficiency of personnel and tasks,the pass field system based on cloud computing is designed and implemented. The goal is to overcome the shortages of existing related systems and to promote its adapt-ability,availability and customization. By cloud computing platform,the system frontier,service of back end and mobile client are de-signed and built. The adopted key technologies mainly contain locations based service,data communication,data storage,data security,da-ta analysis,concurrency control and information pushing. Mainly implemented functions include cloud locating, cloud communication, cloud work,cloud study. Meanwhile,some possible questions and related strategies are illustrated. The applied technologies are Nginx re-verse proxies,Tomcat server clusters,Redis cache,MySQL and MongoDB,and so on. It has been deployed and published in public cloud platform,and provides cloud services based on SaaS,including locating,checking in,scheduling and sale. The applications have good per-formance and obtain management effects and social economic benefits. The implemented system posses good adaptability,availability, customization and responsibility,and its related technologies application may be referred by cloud computing based application systems.%外勤、出差人员与企业决策者之间经常存在实时沟通困难的问题.为降低企业管理成本,提高人员管理、任务调度管理的效率,设计和实现了基于云计算的外勤通系统.目的是克服现有相关系统的不足,提高通用性、易用性、可定制性.借助云计算平台,设计和构建了外勤通后台、前台和手机端模块.主要通过位置服务、数据通信、数据存储、数据安全、数据分析、并发控制、信息推送多技术相结合,实现基于云计算的云定位、云沟通、云工作、云学习;探讨了系统应用中可能存在的问题与对策.系统实现采用了Nginx反向代理、Tomcat服务器集群、Redis高速缓存、MySQL和MongoDB数据库等技术.基于云计算的外勤通系统服务平台已部署和发布到公共云平台,为多家企业用户提供基于SaaS云的定位、考勤、调度、营销等服务,取得了良好的管理效益和社会经济效益.实现的系统具有良好的通用性、易用性、可定制性和响应性,其技术应用可为基于云计算的应用系统构建提供借鉴和参考.
