Dynamic Evacuation Guidance As Safety Critical Application In Building Automation

In building automation systems a bunch of very diverse applications have to be executed at the same time. This includes applications with special safety and security requirements. One of these applications is the dynamic evacuation guidance, i.e. electronic signs which show the direction of the most fortunate evacuation path from public buildings like schools, universities, office buildings or buildings of public authorities during emergency situations like fire or also terrorist attacks. In this context we explored the new and innovative solution Flexit, focussing on safety issues of the communication infrastructure.
