The Application Of Web Service Technology In Embedded Monitor System

With the continuous development and progress of the society and the economy, people pay more and more attention to security issue. In the process, Video monitor technology play an important role, and the development technology of the Digital Video Recorder (DVR, Digital Video Recorder) as a core part of the video monitor system has also been widely used.Based on existed embedded monitor system, the paper main focuses on the application of web services technology, including embedded Web server and the remote monitor client based on GoDB development platform. The main work of the paper as the following aspects. The design and transplant of embedded Web server:According to the actual needs of the system, analysis basic goals, basic functions and concrete realization of the Web server in the system, transplant and configure of the boa server; The design and implementation of the remote monitor client:proposes the design framework of the remote monitor client, clears module division of its basic function, realizes each module on the GoDB platform, mainly including video play module, setting module and other module; Cost-effective security authentication mechanisms:According to the actual needs of the system, the system uses basic authentication security policy, reduce the occupancy of embedded system resources, and improve the responsiveness of the system, the user is divided into administrators, users and observers, different privileges users has different level of operation; Complete the analysis and realization of the system required PTZ module and the client program is designed as an ActiveX control integrated into the embedded system, so that users can be very convenient to manage and configure remote monitor system; Comprehensive and complete system test of the system, gives the test content, test plans, test environment, and analysis of the test results.With the continuous advancement of technology and the limit level of author, the paper proposes some inadequacies and improved methods of the existing scheme at the end.
