| REMOTE & DIGITAL TOWERS | ADVERTORIAL | workstations and the outsourcing of computer technology, control rooms can be converted into a remote tower. Remote computer technology is made available at the workstations via a KVM matrix switch. Operators can access the remote computers in real time via console modules (CON). The fully redundant design of the systems with a completely mirrored matrix switch guarantees maximum reliability. Outsourcing the technology increases security because the systems can be better protected against external access in a separate room with high safety precautions. When systems need maintenance, users can continue to work undisturbed at their workstations, while technicians check and maintain the computers. At the workstations, ATCOs benefit from more space, less noise, and less heat. Ergonomics at the workstation are further improved by eliminating the need for additional monitors and input devices such as mouse and keyboard, since it is no longer required to use one monitor per source to operate different computers. Multiple computer sources can be accessed and controlled in real time via one monitor. As a result, the workspace is clearly arranged and counteracts the “congested controller working position”. Video performance KVM lets you pool and relocate computer sources while operating them in real time. The technology ensures high performance for optimal hand-eye coordination. At the same time, it is easier to visualize image/computer sources on large-screen projectors. In addition to high-performance transmission, KVM solutions can also be used to optimize workflows. With KVM switches, it is possible to switch to other computer sources in real time, whereas software programs cannot perform this without delay. Redundancy for the video gallery A sophisticated redundancy concept is essential in critical environments. In almost all variants of the Digital Tower, the functionality of the video screen is crucial, as air traffic controllers no longer have visual contact in the event of a failure and can only rely on radar technology. While aircraft on the ground cannot take off and aircraft in the air can circle in a holding pattern until technical faults are corrected, the situation is more difficult with aircraft that are already in landing approach. Since the controller in the Remote Digital Tower cannot issue the “clear to land” by looking out of the window, the transmission of the video signals must be permanently guaranteed. In case a computer cannot be accessed, a KVM solution can be used to switch to a mirrored, redundant video wall server system at a keystroke. This guarantees continuous monitoring of the airport apron even in case of an incident. Consolidating processes through digitalization While originally one monitor per application was used in the tower, now systems, which have a positive effect on the controller working position, are increasingly preferred. For example, various software 37 |
