The Design And Implementation Of Intelligent Elevator Video Monitoring System

With the rapid advancement of urbanization in China,elevator plays an increasingly important role in people's lives,but the elevator safety problem comes behind.At Jiangsu Special Equipment Safety Supervision and Inspection Institute Wuxi Branch's request,this subject designs an elevator video monitoring system to monitor elevator safety.This subject focuses on the overall construction of this system.First of all,this paper introduces the research background of this subject,the research status and the main research contents,analyzes the system requirements and designs the system architecture.This system includes streaming video module,web application module and client module.It relates to camera,streaming media video server,cloud storage platform,load balancing server,web application server,database and client.Then,this paper introduces the design and implementation of the intelligent elevator video monitoring system in detail.The camera in the elevator realizes the collection of video data;the streaming video server,which is deployed distributedly,stores the massive video data and responds to the video request from client;the video cloud storage platform backs up the video data of special elevator based on Alibaba cloud object storage service;the load balancing server implements load balancing of high concurrent requests from the client based on the source address hash algorithm;the application server adopts the cluster deployment plan,provides functions such as user information management,device information management,and elevator alarm push based on the SSM framework;the system center database uses MySQL and Redis to storage non-video data and cache hot spot information;the client is browser,provides users with a user-friendly system operation interface based on front-end technology and ActiveX technology.Finally,this paper builds testing environment for this system,and tests the system from both functional and performance aspects comprehensively.The results show that the system can meet the design requirements.
