Application Of Computer Technology In The Digital Monitoring System

The use of Digital Video Monitoring System from simulated age, digital age to now Network age becomes more and more important in every walk of our life. And the use of Digital Video Monitoring System in network is deemed to the direction of the it's development.The first chapter mainly introduces the history and present situation of VideoMonitoring System's development, analyzes the typical system models of Digital Video Monitoring System on its diferent developing stages. The future of the Digital Video Monitoring System is also forecasted in this chapter.And then the second mainly talk about all kinds of key technologies of Video Monitoring System, including the compressing technologies and the network transporting technologies about video signals. In details, chapter 2 focuses mainly on the compressing technologies, including the necessary, feasibility and the comparisons of various international image-compressing standards about their functions and features. Then, MPEG-I is chosen as the compressing standard used in this system according to the requirement of the system.The third chapter discussed and researched Digital Video Monitoring System in Network's capability and configuration, but also designed some of fuctions. The thesis devided Network Digital Video Monitoring System into three parts. There are Digital Video Recorder, Digital Video Cortrol and Digital Video Sever. The thesis introduced every part of it's capability and configuration, and explain some emphasized pivotal technique.In the fourth chapter, The principle, structure, function and engineering consideration of the computer monitoring system for transformer substation automation are introduced.. And give an a kind of proceed owing to every kind of calculator Spread to feel Signal the processed computer monitoring system.. The computer alarm system connect to the head supervises and control the equipments by the correspondence connects by the host. The video server transmits the video, audio and control signal between them.This text has introduced some main functions to the Monitoring System of traditional simulation emphatically, can be replaced and realized to adopt the computer technology among the Digital Monitoring System. Thus the structure of the reduced system, has improved systematic stability and dependability. Accord with the digitization in the present information-intensive society, networking, intelligent development trend.
