Application Of Intelligent Video Monitoring System In Railway

In recent years, China’s vigorous development of high-speed railway, the construction of the passenger, passenger dedicated railway in these, adopt the intelligent video monitoring system of this kind of information technology means to ensure the safety of railway transportation.However, we also see that the video monitoring system in railway application mainly concentrated in the passenger dedicated railway line, and the systemfunction, performance and application mode, application range links more obvious limitations in to meet the demand of railway traffic securityincreasingly efficient hand more and. At the same time, not only the high levelof passenger dedicated railway line has a large demand of video monitoring system, video monitoring system has made a strong demand in the overall monitoring of existing railway line.In recent years, with the rapid growth of network bandwidth, the development of computer technology, image processing technology improves, video surveillance technology has made great development, video monitoring is applied more and more widely infiltrated into security, education, entertainment, health care and other fields. In the course of development ofmore than20years short, video surveillance system has experienced from the first generation analog system (VCR), to the second generation part of digital system (DVR), and then to the third generation of the development of the three stages of the system completely digital network evolution.Correspondingly, the development of video surveillance technology has experienced analog control technology, three different stages of digital and network monitoring techniques.Railway intelligent video monitoring system directly serve production, the railway passenger and Freight Transport Ministry of railways, railway,passenger dedicated company at all levels according to the requirements of users can choose real-time call or playback the video image acquisition point,is an important means of monitoring the safety of transportation. With the rapid construction of passenger dedicated line, it becomes increasingly important for intelligent video surveillance system maintenance work,according to the Ministry of railway maintenance management requirements.the Bureau in accordance with the actual situation in the tube are respectivelydeveloped intelligent video surveillance system for pipe maintenance management mode, delineated by the maintenance division of interface. various plans for emergency disposal.Although the video monitoring technology has been born for a long time, butno matter from the angle of video content processing, transmission platformperspective or from the application of the comprehensive point of view, are far from reaching a mature, also has the very big development space. The development of video surveillance technology depends on the video processing technology (including video codec technology, pattern recognition technology and video retrieval technology), foundation for the development ofnetwork technology and the related information integration technology, closely tracking the development of these basic technology and its application, is the fundamental way to grasp the development trend of video monitoring technology.This paper describes the application of intelligent video surveillance in the railway industry and the development status of railway intelligent video surveillance system, describe the function performance, structure of the system, in combination with the related key technologies of the current video surveillance, clarify the development direction of the future railway video monitoring system technology and application.
