The Research And Implement Of Coal Industry Enterprise Mobile Application System Based On 3G

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.
