Analysis Of The Architecture Of Expressway Video Surveillance System And Its Key Indicators For Engineering Application

The video surveillance system on the highway is a large-scale complex system.Nowadays,the construction mode that establishes a video surveillance system just by putting the equipment together makes the system underperforming.This paper focuses on the highway video surveillance system application entry point,to video event detection function of the camera application and integration platform system on the in-depth analysis,high integration application system after structure optimization study to improve and build the highway video surveillance system brought about by the simplified efficiency.The main work and research results of this paper include the following aspects:Firstly,this paper studies the common architecture of the expressway video surveillance system at present,summarizes the various functional modules in the system,analyzes the hardware components of these functions,seeks for their similarities,and makes integrated optimization,and concludes the optimized system architecture.Secondly,the system structure after optimization is discussed and analyzed.By using Markov process analysis,the stability and reliability of the system after the optimization are improved,and the more visual results are given in combination with the parameters of the actual project.Thirdly,taking the signal source of video event detection as an entry point,this paper analyzes the loss of details and quality degradation caused by the transmission to the back end of the detection signal source in the conventional mode,and obtains the improvement of the detection accuracy in the detection signal source after the optimized architecture.Fourthly,according to the analysis of the construction difficulty direction of the optimized system structure,the construction difficulty coefficient of the conventional mode and the optimization model is analyzed by AHP method,and the contrast analysis is carried out.The difficulty coefficient ratio of the two models under different construction scales is displayed through the visual difficulty coefficient curve.Fifthly,by analyzing the support range of the peripheral system required under the two different modes,the paper analyses the network bandwidth,the space of the machine roomand the energy consumption,and combines the basic data of the actual project,and obtains the occupancy of the resources under the different construction scale and the two modes.
