Background
Video monitoring system is need to provide uninterrupted dynamic information change of areas, such as tunnel, intersection, toll gate, turning, accident prone area. Deploying such large scale video monitoring control system requires the knowledge of network infrastructure and communication. Primestone engaging in R&D of industrial communication products, producing, and technology guidance, by using mature optical communication technology, to realize a HD fluent video monitoring system.
Requirements
High reliability , video monitoring uninterruption for a super long time
Industrial network redundant technology, fault fast switch
All GE fiber backbone network, meet with extra large video traffic transmission
Industrial design, wide range voltage input, anti vibration, damp proof, hardware protection
Reasonable network deployment, powerful software, increase the usage of bandwidth
High reliability, unattended
Standard industrial ports protocol, with good extension, compatibility, and reliability
Solution
IS3000 full gigabit switch, mounted at video monitoring points of every intersection, to make a ring Ethernet, up-link core switch of control center, the core switch is IS6000 series, multiple ports L-3 switch. Every monitoring pole mounted with IS1000 series DIN rail switch, IS1000 is unmanaged DIN rail slim switch, small size, high cost performance, cameras linked with IS1000 by cable, IS1000 linked with convergence IS3000 by fiber. Every IS3000 switches make redundant ring network through fiber ports, redundant links can meet the requirement of large scale video data transmission. Switch with the functions of tag VLAN and IGMP snooping. tag VLAN marks on every frame, and then send video to regulated destination VLAN, so no need to configure video stream at every physical port, save processing capability up to higher transmission efficiency. in addition, IGMP snooping by means of removing multicast blocking, to reduce produce of multicast messages,. Due to the wide range, many road periods, Primestone suggests to adopt 100M video acquisition, gigabit fiber port to make converge and backbone network at access layer, and ERPS protection, recovery time <20ms, ensured that video data fluent transmission, and zero package lost.
Benefits
Abundant, reliable, multiple redundant technology（ERPS）
Mature security mechanism, TAG VLAN and IGMP snooping.
Extra back panel and cache, ensure all GE high bandwidth, fluent without blocking transmission Anti-interference, anti-corrosion, adaptive to high and low temperature, unattended operation. Whole network meet with GB/T 30094-2013 national standard
Extra long frame, jumbo frame transmission, meet with various video compression algorithms
Small Cabinet dimension, multiple ports, single area multi-node DIN -rail mounted
