Design And Application Of Video Surveillance System Based On Broadcast And Television EPON Network

Radio and television network company as a local cable TV network operators,every corner of the rich quality of fiber network throughout the city,digital cable TV two-way transformation being around,the radio and television network upgrade from one-way transmission to two-way interaction,with the high clear video surveillance base.Based on the EPON video broadcasting network safe city project construction has changed the traditional business model of digital TV single,enrich the types of cable operators to develop value-added services,enhance the radio and television network operators in the city informatization construction in the competition.This topic based on cable TV company can tube controllable security video transmission private network,designed and implemented a carrying more than 2000 hd monitor point,24 hours a day,"safe city" of high efficiency and reliable security video surveillance network system.Thesis around the radio and television networks company "safe city" project,the design and implementation of the first to the video monitoring technology background and EPON transmission technology are expounded,and then presents the overall design of the system and special design,concrete including monitoring system,EPON of radio,film and television video hosting private network and system docking between three parts.The thesis focuses on the following two problems and puts forward the solution.First,by analyzing the business requirements and the network of the safe city project,design the different application scenarios PON solution,namely the area of urban fiber resources nervous with PON network load,long distance and using optical transceiver bearing point spread area.Then,in view of the operator network video private network connectivity between safety and the security problem,design a "double network double platform system architecture,solved the cross-platform safely and efficiently transmission between video and data signals.Finally,the project has been officially put into use,and cooperate with the public security and comprehensive management department to solve a number of cases,to a significant effect on the safe construction of the rule of law and the comprehensive management of social management.
