Design And Implementation Of Web-based Intelligent Video Surveillance System

There are equipments from different manufacturers in the system integration of intelligent buildings. It is not convenient for integration and management to use all kinds of application software and communication protocols. So it is an insistent problem to establish a uniform communication protocol stood by all manufacturers to get a standard integration of sub-systems in buildings. BACnet is a data communication protocol for building automation control networks. The prime purpose of BACnet is to provide an interoperation method for building automation control system. Under the rapid development of network and communication technology,more information and automatic control are demanded at home. All these are based on intelligent home network. BACnet is an open protocol, which is a standard data communication protocol about the building automatically controlled network. It has already been the ISO standard,and used widely in many countries At the same time,the video surveillance system is an important part of intelligent building security system. Therefore, BACnet based intelligent home system which adopts the video surveillance system has many potential applications.First,the structure of intelligent home system based on BACnet is analyzed. After the brief introduction of video surveillance system history,the importance of video surveillance system in BACnet intelligent home system is explained.Then, introduced the conception of home information center HIC, HIC is the core of the whole intelligent building system,video surveillance system is a part of it. On the basis of these,the structure of the video surveillance system is analyzed. The whole system design and each sub-system software design are presented in this thesis.Secondly,the video capture,motion detection and JPEG compress is studied and analyzed,which is the fundamental component of video surveillance system. After this,some key technologies in system software implementation are analyzed,and given the video surveillance system an all-round test.Finally,conclusions of the system are presented,and some propositions about the direction and contents of further research are suggested at the end of this thesis.
