The Design And Implementation Of Video Systems For Power Engineering

With the development of network technology and computer applications, the majorcompanies organs of enterprise information technology vigorously promotetechnological innovation and management of modern enterprises fine.Such as newpower engineering video management system using video and audio capture technology,data compression technology, network transmission technology, data storage and fileanalysis management techniques that can have an effective solution to powerconstruction site construction difficult to record the problem difficult to find theproblem, andthe video files and field work have formed video file conversioncompression to form a unified electronic format, stored in the back-end, low-costpowerful HDFS-Step cluster file system, the use of Hadoop framework for thedevelopment of video management applications canquery support fast audio and videofiles, read, downshift and recovery operations. The global video data sharing, staff andleadership in the power system by the system in the State Grid Energy Company OA tovideo data Tiaodang in, improve efficiency, save time and office travel overhead.This paper introduces the video management software system of technologicaldevelopments at home and abroad, and the power internal development planning andneeds to start, to business needs and the use of personnel to determine the hierarchicaldesign, distributed memory, integrated architecture designed by the bus. Front-endvideo capture for video and audio acquisition, conversion, and sending; backendmanagement center is responsible for receiving data, the overall control, data storage,file management is responsible for data and video files Find the video files, video filesplayback, video copyright management control.The main content of this paper is the Design and Implementation of the rear-endcenter subsystem and file management subsystem, first introduce the overall frameworkand module division of power engineering video management software system,describes the main functions involved in focus and key technologyimplementation,innovations include: HDFS distributed file system, distributed datastorage, high reliability, low cost and efficient management of image files to ensure that audio-visual file system. Control technological innovation of video data using SIPcontrol session set-up of the front-end data acquisition and transmission, the back-enddistributed storage and playback capabilities to achieve specific business and technicalcontrol separation, flexible architecture, compatibility audiovisual collection of IPnetworks and traditional communication network andtransmission; and the mainfunction of the system using a standard Web services technology package, the basicfunction of the components and conducive to business development.Finally, this article describes the video management system in the actual projectimplementation functions and specific applications, and the direction of technologicaldevelopment of the audio-visual management system and business development issuesfor discussion and outlook.
