Design And Implementation Of The Video Monitoring System In Factory

Security engineering is necessary for enterprises, and video monitoring system as an important part of security engineering, more and more be taken seriously. With the continuous development of network technology, data communication technology, video monitoring system used in the factory to upgrade quickly.In this thesis, corresponding to the Shan Dong Yan Kuang light alloy co., LTD., the factory has carried on the design and development, video monitoring system based on user demand for the use of the system, constructing the overall architecture of the system, the system operation of each main link building applying the latest technology, effectively improve the efficiency of monitoring. Specific work includes: to build the overall architecture of the network video monitoring system, through the analysis of traditional video monitoring system, find the existing problems, respectively, in video data acquisition, transmission, storage, monitoring solution in four links, finally formed a relatively mature network video monitoring management system framework; In the transmission of video data, synchronization of audio and video data for more in-depth research, based on RTP/RTCP protocol timestamp synchronously realize video data synchronization solution, and build the audio and video packets control module, considering the media data transmission under different network congestion control scheme; In monitoring mode, the automatic monitoring alarm function based on moving target detection algorithm, the background difference method is adopted to detect moving targets, based on the realization of the background image reconstruction the gaussian mixture model, effectively improve the effectiveness of the moving target detection, changed the past monitoring equipment record image data only, do not have active alarm function, can make the system offer attendant alarm information, effectively improving the capacity of the security monitoring system; In regard to the development of client application software, detailed analysis of the needs of monitoring personnel for system use, will be the function of the monitoring center software is divided into different modules, to meet different business process monitoring.Thesis first analyzes the factory video monitoring system design and development background, the system design and development as the key technologies involved are discussed. On the system demand analysis, and on the basis of the demand analysis on the system’s overall architecture scheme design and discussed. The use of programming languages, the main functions of the system to realize the module, and use the test cases to test the functionality of the system and performance indicators. Factory video monitoring system design and development of application of the current advanced video processing of the monitor and control technology, can effectively improve the efficiency of monitoring, saving construction cost, and has good practical value. At the same time, to monitor audio and video synchronization problem, and research of moving object detection, has certain theoretical value.
