Husovicky Tunnel in Brno, Czech Republic Husovicky tunnel was built in 1999 with the objective to ease traffic congestion between the east and north districts of the city Brno in Czech Republic. It is approximately 600 meters (0.4 miles) long. Thousands of cars pass through every day. In order to enhance the safety in the tunnel and make the tunnel maintenance more efficient the previous obsolete automation system. Monitoring traffic signs, lights and ventilation was replaced by a new automation technology in 2012.
The new control system is based on progressive modular system of ControLogix PLCs and myBOX following the latest trends in automation in performance and security. All visualizations are made in mySCADA Editor and deployed to PCs in the control rooms as well as to iPads that are used as local operators‘ touch panels. The operators can retrieve online system data in the control room as well as in the field. The authorized operators can change the alarm activation values, alarm description, severity, action mode and notice delivery (SMS, e-mail). All history data are logged with 1-second precision in myBOX and available on request anytime, so that the operators have a full control over all events and alarms. With the remote access the system can be accessed 24/7 from anywhere while ensuring system safety.
