基于3G煤炭企业移动应用系统的研究与实现
摘要
随着信息化促进工业化水平的提高以及宽带无线网络技术的蓬勃发展,3G通信网络已经在网络承载能力、带宽、用户体验、QoS、安全性等方面不同程度上满足企业移动应用的需求。煤炭行业对于安全生产指挥调度的要求有了新的变化,他们不光希望可以通过有线的方式获得企业的第一手生产信息,而且希望通过利用新的技术满足更高的用户需求。因此,研究煤炭企业移动应用系统具有重要的实用价值。
本文在研究了企业移动应用相关理论背景的基础上,实现了3G网络背景下的煤炭企业移动应用系统,并将其应用到具体的企业安全生产监测系统上。首先描述了支撑企业移动业务的硬件平台,并且建立了系统的物理模型,研究了在宽带无线网络中移动终端与企业服务端之间的信息交互技术。其次,在分析系统逻辑模型的基础上,对系统软件平台进行设计并提出J2ME与J2EE集成企业移动应用解决方案与整个系统MVC的系统架构。然后具体设计并实现了客户端的实时数据模块、流媒体模块、服务器端模块。最后将该移动应用在陕西亭南煤矿进行现场测试,该方案扩展了亭南煤矿已有的企业安全生产监控系统的功能,实现了实时数据及流媒体服务的移动客户端监测功能,并且设计了系统的安全策略。从该系统性能测试的结果看已经达到了企业应用的水平,随着3G时代的来临,具有广阔的应用前景。
With the industrialization propelled by information technology and the thriving of technology of broadband wireless network.3G communications network has been able to meet the various needs of enterprise mobile applications, such as network carrying capacity, bandwidth, user experience, QoS, security and other aspects.It is going to change for the requirements of command and dispatch of coalmine safety production of coal industry.They not only urge to get the first hand information by the cable network, but also want to meet the higher needs of users through new technologies.Therefore, It is of practical value for the Research of mobile application systems for coal enterprise.
This thesis studies the theory of mobile application for enterprise.It describes the process of realizing a mobile application system for coal enterprise. It takes a mobile command and dispatch of Coalmine Safety Production system as an example. It introduces the hardwares used for supporting mobile application and build phisical model of the system.Then it introduces the information exchanging technology between mobile terminal and enterprise server in broadband wireless network.Secondly,based on analysis of logical model of the system, it determines that solution of the system is J2ME mobile applicition of enterprise integrated with J2EE.Thirdly, it decribes the process of realizing data module, stream media module and server module on the client side.Finally,The solution is applied for test in Mobile Safety Production Monitor System of Ting Nan coalmine, making the system hava the capacity to expand the system and monitor the realtime data and multimedia at mobile terminal. Then design the security strategy for the system. It can be used in the enterprise based on the result of testing performance of system and can be widely used with the coming of 3G.
