Application Of Windows DNA Technology In Video Monitor System

With the development of the multimedia and communication technology, Video Monitoring System has been applied in the electrization railway transformer substation. And the most popular technology ?Windows DNA has been applied in many aspects of industry. It' s no doubt that the cooperation between them would bring us more reward.The thesis is written to meet such demand. It starts with Video Monitor Center Software of electrization transformer substation, analyses Video Monitor System combining the technology of Windows DNA, designs the COM component of user management, alarm record and operation record management used in Video Monitor System, analyses the whole framework of Distributed Video Monitor System, and makes a through analysis of its security.The thesis discusses the application of Windows DNA in Video Monitor System and introduces how to design the three-tier architecture of the data service layer, business logical layer and presentation layer, and emphatically introduces security setting between these layers. SQL Server is implemented in data service layer and database access used by ADO technology. COM component techology is utilized in business logical layer, and Windows Forms and ASP Web pages are employed in presentation layer. User management, alarm records and operation records are very important in Video Monitor System. How to manage them in the Windows DNA architecture must be considered.The thesis expounds the application of the Windows DNA, COM Component and do management, achieve most functions of them. And it discusses helpfully the application of Windows DNA technology in the Distributed Video Monitor System.
