City of Industry, CA, United States, 12/23/2008 – Beijing is China’s second largest city, after Shanghai. It is a major transportation center, with dozens of railways, roads and motorways passing through the city. To improve the heavy traffic during rush hour; public transportation and intelligent traffic system are often introduced in nearly all metropolitans. For intelligent traffic system, it requires Ethernet redundant mechanism, RS-232/422 to Ethernet converter to remote control traffic light and other traffic sign/ display. Fiber converters become a must since the remote control center maybe located tens of kilometers apart.
In the diagram above, each circle represents 4 sets of traffic light from 4 intersections, and the traffic information is collected and transmitted back to the traffic control center instantly through the JetCon3401G’s Fiber connection. JetPort/JetCon Series is the best combination for the traffic control application operating under harsh environment. Connecting the JetPort 5601 to the traffic light controller and link to the JetNet 4508f through Ethernet then report those signals to the control center. By using this network architecture demonstrated in the picture, it provides Ethernet Ring redundant solution assuring a non-stop data transmitting to the traffic control system. Fiber module in single mode of the JetNet 4508f extends the network connectivity.
Main Products:
• JetNet 4508f Industrial 8-port Managed Fiber Ethernet Rail Switch;
• JetCon 3401G Industrial Gigabit Ethernet Media Converter;
• JetPort 5601 Industrial 1-port RS-232/422/485 Redundant Serial Device Server.
