Ethernet controllers for traffic management systems

Korenix Technology : 22 December, 2008  (Technical Article)
Korenix explains how its JetPort and JetCon Series are ideally suited for use in intelligent traffic control systems
Beijing is China's second largest city after Shanghai. It is a major transportation centre with dozens of railways, roads and motorways passing through the city. To improve the heavy traffic during rush hour, public transportation and intelligent traffic systems are often introduced in nearly all metropolitans. Intelligent traffic systems require Ethernet redundant mechanisms, RS-232/422 to Ethernet converters to remote control traffic light and other traffic signs/ displays. Fibre converters become a must since the remote control centre maybe located dozens of kilometers apart.

The JetPort/JetCon Series is an ideal combination for traffic control applications operating in harsh environments. Connecting the JetPort 5601 to the traffic light controller and linking to the JetNet 4508f through Ethernet then reports those signals to the control centre. By using such a network architecture, you are provided with an Ethernet Ring redundant solution ensuring non-stop data transmission to the traffic control system. Using a Fibre module extends the network connectivity further.
