The Research On Fire Warning System For Tibetan Ancient Building Based On Embedded Technology

The designed system can monitor and collect the information of the indoor and outdoor scenes of ancient buildings through the front-end equipments. All front-end equipments build a Zig Bee network. In the network. the coordinators transfer the image information colleteced by the front-end equipments to the back-end embedded devices through wireless Ethernet, The corresponding back-end embedded devices achieve image analysis and get the results of fire warning signal. The information about the entire ancient buildings can be sent to the users and managers immediately for achieving the purpose of fire control.The thesis mainly discusses the system software and hardware environment structures, gray image processing, gray image Zig Bee transmission process and related Linux application development and has carried on the related research and analysis. First select the corresponding hardware equipment, by using the corresponding development platform to development and configuration related equipment, constitute a Zig Bee network. In the process of network topology structures, the system improved self-organizing network’s survivability by the application of cluster random algorithm based on energy control. Then the thesis does some related research and analysis for the image processing algorithm on the the front-end and back-end, combining the characteristics of the fire image, the thesis give the whole system of image analysis and determination process. In practice, on gray image transmission problems in the related network the system need do some corresponding research and analysis.such as image compression and decompression algorithms, wireless Ethernet card embedded driver design. Finally, based on embedded linux application development the thesis do some related research and analysis.To make the system can play a better ability to protect Tibetan ancient architecture, to adapt to the realistic environment of Tibetan ancient architecture, the thesis mainly study on the innovation in the following aspects: the network is set up to adapt to the Tibetan ancient architecture community site environment, eliminating the influence of the ancient buildings such as internal Su You Deng inherent flame, eliminating the influence of the moving targets such as the tourists, etc.
