Field Task Oriented Auxiliary Support Of Mobile Terminal Software System Research

Since the beginning of the21st century, with the technological advances of circuit materials, structural design and computer manufacturing processes, as the representative of mobile devices to smart phonces has been rapid development of mobile computing technology in the industrial enterprises gradually moving towards the practical stage. The major domestic and foreign research institutes and famous universities have set up the relevant research centers and laboratories, focused on mobile computing technology in the industrial, military and other main areas of research.At present, the research on mobile computing software in field of industrial enterprises application still exists many difficulties and challenges, mainly reflecting on the software based on traditional software developing can not effectively meets the needs of mobile computing applications and there is a big difference between the interactive mode with the traditional desktop and mobile devices. On the other hand, the software supporting technology for industrial site on the mobile devices which is still at the exploratory stage, can not provide effective support for mobile computing software research.In view of above analysis, as the background of mobile computing in the industrial enterprises task assisted application, for the typical functional needs of industrial enterprises operator such as remote assistance, teamwork, device status monitoring, tehnical manuals help, combined with the integration of requirements of the software infrastructure and the application status of technologies such as sensors and wireless transmission sense network, mobile interaction and Web service, this paper presents that based on OSGi(Open Service Gateway initiative) Building a field-oriented tasks assisted mobile computing terminal supporting software system which trying to create a modular, scalable, dynamic system framework, supporting man-machine natural interaction and adaptive function man-machine interface, to provide supporting system for mobile computing in the promotion and application for industrial enterprises. Main content and innovation can be summarized as follows: (1) on the basis of the study and compare of related technologies, the specific needs of field-oriented tasks assisted mobile computing terminal supporting software system, this paper designed a modular, scalable and dynamic distributed software infrastructure framework by combining OSGi, R-OSGi and SLP(Service Location Protocol). On this software infrastructure framework this paper build a four-layer and suitable for OSGi framework which is composed of the network layer, logic layer, service layer and presentation layer.(2) Based on the OSGi software architecture, combined with the industrial demands of field operations, this paper designed and implemented the specific functions:text assistant, whiteboard assistant, audio and video assistant, technical manuals help, equipment condition monitoring and functional modules dynamic management.(3) Combined with the using feature of industrial field operating assistant system, according to the dynamic nature of OSGi software framework, this system implements dynamic management and management strategy of all the functional modules as well as the service they provide.
