Design Of Messaging System Based On Android Mobile Terminal And PC

It makes the engineering construction field expanding with the electronicsindustry in each passing day, the wide application of computer technology，and thewidespread using of modern large-scale machinery and equipment, but theconstruction environment difficult also goes hand in hand. It may result in theengineering technical personnel and project management personnel separated fromthe construction site for the situation such as construction of acid and alkalienvironment, heavy machine operation, work high above the ground. With the sceneimage acquisition transmission is very necessary. And in view of the specificconditions of construction it requires image transmission of real-time andconfidentiality, therefore, setting up enterprise instant messaging platform is timely.This issue is based on the realization the safety and privacy of enterprise-level IM.theresearch chooses an Android smartphones as mobile terminal, aiming to building anAndroid terminal and PC instant communication platform.System design scheme chooses Client-Server communication mode.The Clientselects the Spark development component with its API extension development, usingthe Openfire Server Web service architecture. The research has designed andimplemented the instant messaging system based on application layer of instantcommunication protocol XMPP and Android development platform. The systemimplements the basic functions messaging, file transfer, and user managementincluded.This essay focuses on the XMPP protocol and other technologies likeAndroid interprocess communications. Finally, we developed a set of IM systemmode. It helped to build their own IM systems for individuals or businesses. Thissystem proposed feasibility solutions to reduce the costs of production, make datatransmits safely. On the premise of accomplished communication basis the issue hasdesigned the STDM digital watermark encryption module on the image transmissionbackground. After developed the system, the author has run an operation test. Fromthe test result, it shows that the instant messaging system could smoothly realize thepreset objectives,and the basic transmission performance is stability.
