| The communist party of China 17 times national congress stressed the need to insist on safety development, strengthen the safety production management and supervision. According to the Chinese communist party 17 times national congress of the spirit, the enterprise needs from two aspects of hardware and software to strengthen the administration of production safety, guarantee the safety of production. Video monitoring system for its image visual lifelike, contains large amount of information, can pass through video long-term preservation, network for transmission management, accordingly it in production safety guard management plays a very important role.As the electronic computer science technology and network technology of rapid development, monitoring technology also follow fast development, video monitoring system gradually from analogue to digital video monitoring systems to improve the network, plus the human society advances, people for security needs are constantly improve, thus to safe guard system equipment put forward higher request, so that to a certain extent it would promote the rapid development of the monitoring system. Network video monitoring system appear, greatly enhances the original video monitoring system function simulation, also increased a alarm, remote control and so on some new functions. This video monitoring system, network Numbers in the development process is gradually replacing traditional analog video monitoring system is irreversible. This paper makes a study of the digital network video monitoring system in the application of the construction of the liner.This paper first analyzes the digital network video monitoring system at qinhuangdao port of the background and significance of research, this paper introduces the development of the monitoring technology and trends, and then introduced the analog video monitoring technology, digital video monitoring system, network video monitoring system of the related theory knowledge, the theory of research behind laid a foundation.Based on these, this paper qinhuangdao port main production unit and security defense department monitoring system upgrading (that is, from the original analog video monitoring digital network video monitoring upgrade to) the feasibility of the project are analyzed.This paper over the course of the study, combined with qinhuangdao psa each branch and department of the monitor system, qinhuangdao port of existing network video monitoring system of digital network upgrading the important problem scheme analysis, determine the goal of the project implementation, and put forward the digital network video monitoring system at qinhuangdao port the network structure and the function demand.Hope this research to our country network video monitoring of rich existing theories, at the same time for network video monitoring system qinhuangdao port upgrading the practice of project to provide guidance and help. |
