Background
In recent years, with the rapid development of social economy, the contradiction between supply and demand is becoming more and more acute. The traffic control department hopes to use the advanced intelligent transportation system to effectively improve the level of traffic management, alleviate the difficulties caused by the lack of police force, to realize "strengthening the police with science and technology, improve the level of law enforcement, provide a good traffic environment for promoting the development of social economy. The electronic police and traffic security monitoring system is one of the most advanced police training means, play an increasingly important role, especially in the specification of road traffic, public security investigation has made obvious effectiveness. The main purpose of the electronic police system is to stop the traffic violation, regularize vehicles, to provide solutions for vehicle violation 24h, strict and feasible, a set of stable and reliable transmission network system is the key of intersection data and the monitoring center data exchange
Requirements
Operating temperature -40℃~+85℃ ,adaptive to various harsh environments
Long distance fiber transmission, link backup, recovery, quick switch
Support extra long frame transmission for MJPEG, MPEG, H.264 and H.265
Standard design, open interface, compatibility, adaptive to traffic industry application
Solution
Long distance transmission and redundant network are two key points. At every intersection, loop sensor connected with flashlight, and trigger IP camera to snapshot. Every snapshot node connects to IS2000 Series switch for data transmission. Snapshot nodes could establish ERPS protection fiber ring, which switching time<20ms.
IS2000 and IS3000 series are equipped with multiple fiber ports, which support flexible networking, meanwhile these two switches support extra frame transmission, can meet with requirement of snapshot burst frame. Combined with Mac addresses of snapshot nodes on switch, enable IGMP snooping to filter multicast data, to secure nodes and processing capability of switch.
Benefits
Industrial quality, Operating temperature -40℃~+85℃, adaptive to various harsh environments
Extra long frame transmission, reduce mistake capture, leakage of capture
Anti-EMI, DIN rail, hi-density, easy mounting
Long distance fiber transmission, hi-reliability, MTBF≥500000h
All network meet GB/T 30094-2013 national standard
Open industrial design, seamless joint to legacy system and extended system
