KVM in the control tower ► Improving the controllers’concentration

The mission-critical applications of the control tower require air traffic controllers’ absolute and constant concentration. That’s why it is so important to provide the very best possible working conditions with no diversions or disturbances. In the limited space of the tower, the noise and heat generated by the powerful processors of the computer system creates an unwanted disturbance.

However, thanks to KVM products such as KVM extenders and KVM matrix switches, the computers can be moved out of the tower to another location a good distance away.This solution not only saves space in the tower but reduces the costs of air conditioning and climate control. In a dedicated server room, computer maintenance is made easier too, with no unwanted distractions from maintenance personnel. KVM extenders transmit computer signals in real-time over long distances with no loss in quality. Controllers can set about their tasks without even realizing they are operating their computers remotely. With KVM matrix switches, the operation of multiple computers can be decentralized via multiple consoles.

How KVM works in the tower

KVM products are an essential part in towers. Once the computers had been removed to a central equipment room, they were connected to a KVM matrix switch, e.g. ControlCenterDigital 288. The extender feature of said matrix switches established connections to offices, the test room and finally up to the flight station with all working positions. All workstations can access any computers that are connected through KVM technology.

Even in the crisis room, users can access and view all computers. The computer signals are even further extended to the safety-sensitive flight station. In a separate testing room, employees inspect any IT equipment thoroughly. And even from here, technicians with specially assigned user rights can access and maintain the computers.

KVM in Air Traffic Control Centres ► Preventive monitoring, Redundancy and Fallback

Coordinating departures and arrivals and controlling overflying traffic requires the maximum reliability of all IT components. Air Traffic Control Centres are sensitive security areas that can enjoy major benefits through deploying a KVM extender such as DL-Vision. This allows computers to be removed from the control centre, improving working conditions and enabling preventative monitoring and event reporting. Regulatory safety demands can be met by integrating the DevCon-Center.

This provides centralized proactive monitoring and configuration of network-capable G&D devices. Depending on results or predefined thresholds, the DevCon-Center triggers and sends a message to the system administrator, allowing them to react before any failures occur. Redundant and fallback systems are essential for the controller´s work. To prevent a total breakdown, three independent systems (primary, redundant, and fallback) are applied to the controller’s desk. Each system consists of a computer and a KVM extender line. By pressing a button at a KVM switch installed next to the desk, switching between systems is made easy

Customer benefits using KVM – Full safety thanks to redundancy and fallback

The unlikely event of a system breakdown despite preventive monitoring requires a concept that allows controllers to continue their work safely and intuitively in their familiar environment. This requires a redundant system that is safeguarded by another fallback system.

Now two functional lines are still available even if the primary connection fails.Three independent but identical systems per controller desk serve for a primary, a redundant and a fallback system. Each of these three systems consists of a computer and a KVM extender line.

The controller only needs to switch between the three systems by simply pressing a button on the KVM switch, e.g. DL-MUX4. Screen freeze function “freezes” the image last displayed on the monitor. Users are provided with the information last received before switching to a redundant system.

KVM Products
