Construction and expansion of traffic light systems in Chemnitz
Connecting outstations to the control centre reduces personnel costs and operating costs for the traffic light systems in the inner-city road network.
The challenge
In Chemnitz, Saxony’s third-largest city, it was not until the turn of the millennium that urban development planning was begun based on the layout of the city centre until 1945. In conjunction with the structural changes, the inner-city road network and the extended connection to trunk roads were also successively modernised using computer-controlled technology. The existing copper cable will continue to be used for this purpose.
Solution
Data is transferred from the branch offices to the control centre to set up and expand the traffic light systems in Chemnitz. The SHDTU Ethernet modems for top-hat rail mounting are suitable for this purpose. A rack solution is used in the control centre, where all the data converges. All devices are connected as a ring.

Benefit
By connecting outstations to the control centre, they only need to be visited in the event of a fault if the central solution does not work. This reduces personnel costs and operating costs. With the technology used, investments in the passive network infrastructure could be avoided
