Design And Implementation Of Video Surveillance Alarm Management System

In recent years,along with the development of economic,the scale of the video surveillance system is also becoming larger and larger.At the same time,advances in software technology also makes the video surveillance system has made great progress.Especially the development of web technology,it enlarged the range of remote monitoring.So people just need to log on the system from the browser,it is very convenient and easy to use.Alarm management subsystem is an important part of video surveillance system.With the expansion of the scale of video surveillance system,the alarm information to be managed by the alarm management subsystem will also be an exponential growth.In the face of such a large scale of alarm information,how to manage them effectively is a very important issue.Therefore,it is very practical and has great significance to research and realize the video surveillance alarm management system.In this paper,we first introduce the key technologies of the system,and study the core issues that the video surveillance and alarm management system is faced with.And then make requirements analysis for the alarm management system,finish the system overall design and detailed design.In the design of the system,efficiency and stability were considered.Because the number of information in the alarm management system is very great,so this system use mutiple storage(Mysql and Kafka)to store the message,and use ehcache cache to improve storage efficiency of reading and writing.This system take information grade into consideration,the server will receive alarm information and distinguish them by level,to ensure that the important information will be handled first and the congestion is avoided.When the server forwards the alarm information to the user,it also considers the important level of the alarm information.In the end,this paper has carried on the demonstration and the test to the system.The system background based on the SSM framework(Spring+SpringMVC+Mybatis)for development,and use Maven to management project.Combined with the characteristics of each frame,the system's coupling is reduced.After test,we can ensure this system can well meet the needs.
