Stage technology for Helene Fischer

Exciting stage effects created by a sophisticated interplay of sound, lighting and moving elements are the prerequisite for successful shows of all kinds. This poses particular challenges for stage technology, especially with regard to the safety of performers and spectators. Stage elements are often moved or even lifted during the show so that they can “float” above the heads of the audience. An impressive example of this is the so-called bird flight in the Helene Fischer show Farbenspiel: singing, Helene Fischer flies over the audience sitting on a giant bird at a height of up to 15 meters and finally lands on a stage in the middle of the event hall. Such an elaborate performance is only possible with powerful stage technology that meets special safety requirements, such as the wireless modules from the DATAEAGLE® series.

The challenge of this application for the stage technology is the absolute safety of the people - as was the case with Helene Fischer's bird flight show effect. Due to the 80 meter long and winding guide rails that lead the bird over the rows of visitors, it is not possible to create a trailing cable connection to the bird. Power is therefore supplied via an additional conductor rail, to which the power electronics are also connected. However, the control commands to this moving system must be transmitted via a wireless connection, i.e. by radio - a particular challenge in view of the required operational safety.

The solution is provided by a PROFIBUS radio data transmission system in which the power electronics are directly connected to the rail as slaves. The DATAEAGLE 3712 radio module with Schildknecht AG's patented data pre-processing takes over the wireless communication between the stationary master and the moving elements. This radio data transmission system reliably filters out short-term radio interference and ensures a stable radio connection. A 2.4 GHz Bluetooth connection is used for radio transmission, which has largely replaced the WLAN technology previously used in stage technology.

The successful partnership between SWL, Fülling & Partner and the radio specialist Schildknecht AG was the basis for the trouble-free performances of “Farbenspiel”, as well as for many other sophisticated stage technology systems. Although the DATAEAGLE radio module is only a small part of the automation technology in terms of value, it is the most important component in terms of functional reliability and availability in stage technology.

Steffen Boschert, owner of SWL, the company responsible for the project, sums up his experience:

"We were very satisfied with the quality and reliability of the radio systems used and especially with the support provided by Schildknecht. With the radio modules used, the required safety standards in accordance with DIN 56950-1* could be achieved."
