Remote Communication for Traffic Lights
Challenge
Modernize network infrastructure and allow remote communication with traffic lights in various parts of Rio de Janeiro.
Solution
Cellular Routers and Bridgemanager System for managing connections with the customer's supervisory office.
Our client had a worn and obsolete RS485 serial network infrastructure, with high maintenance costs. I needed a remote communication solution that was robust and reliable enough to control hundreds of traffic lights in certain regions of the city of Rio de Janeiro. The application was critical because, as in any large metropolis, the city could fall into chaos in the event of a failure in communication with the controllers.
Above-Net provided the solution through industrial and resistant cellular routers, combined with the Bridgemanager system, responsible for monitoring and managing connections. This solution allowed transparent communication via Internet/VPN between the CCO and the traffic light controllers and generated important data for the customer on the status of connections, data traffic and signal level.
The products and systems involved in the solution are industrial and prepared for critical operations and large volumes of connections:
- Robustel R3000-L3P – Dual-SIM cellular router with 1 Serial port and 1 Ethernet port;
- M1000XP – Cellular Modem with Serial port;
- Bridgemanager – Cellular connection management and monitoring system. Hosted in a redundant datacenter, it guarantees reliability and robustness for large volumes of connections. In addition to allowing a transparent link between the supervisory and equipment spread out in the field, it generates data and information about signal level, location, connection status, among others.
This solution has been in operation for some time and was replicated by the customer in other cities due to its reliability, high availability and excellent cost-benefit.
