During Superbowl XLVII, utility power feeding the Superdome in New Orleans was partially interrupted. This resulted in numerous issues with the stadium lighting resulting in over a 30-minute delay in the game. Following this event, extensive audits of all systems commenced in an effort to gain a comprehensive understanding of any shortcomings so that appropriate improvements could be made.
The original stadium lighting control system featured several layers of complexity and had become outdated. The goal was to reduce the many points of failure between a light fixture and its power source. To accomplish this, Square D Powerlink smart breaker panels were installed to replace the 24 existing breaker panels. Computrols CBAS (Computrols Building Automation Software) was installed to provide the graphical interface and scene control programming. A high-speed fiber optic network was installed from each of the 4 lighting quads to the main control room, ensuring the speed and security for proper operation of the system.
To help provide real-time visual confirmation of both scene and lamp status, four High-Definition IP cameras were installed and connected to the system. Redundancy and reliability were key requirements of the upgrade. The Computrols “Dual-DPU” feature was alos deployed. This allows two servers to run simultaneously – should one experience a failure, operators can seamlessly transfer operations to the other machine with no downtime.
By eliminating several points of failure, the Mercedes Benz Superdome now has a simple and robust sports lighting control system that fully addresses the many shortcomings of the prior system. Building operators can be confident that should another power interruption occur, they will maintain full control of the system once power is restored.
