The Karabo distributed control system.

Abstract: The Karabo distributed control system has been developed to address the challenging requirements of the European X-ray Free Electron Laser facility, including complex and custom-made hardware, high data rates and volumes, and close integration of data analysis for distributed processing and rapid feedback. Karabo is a pluggable, distributed application management system forming a supervisory control and data acquisition environment as part of a distributed control system. Karabo provides integrated control of hardware, monitoring, data acquisition and data analysis on distributed hardware, allowing rapid control feedback based on complex algorithms. Services exist for access control, data logging, configuration management and situational awareness through alarm indicators. The flexible framework enables quick response to the changing requirements in control and analysis, and provides an efficient environment for development, and a single interface to make all changes immediately available to operators and experimentalists.

Effects of Robot Control Mode on Situation Awareness and Performance in a Navigation Task

Abstract: Our ability to complete tasks in remote environments has improved with increased sophistication of robotic systems. The quality of remote task performance is driven by the quality of human interaction with robots which can be dependent upon the operator's ability to acquire situation awareness (SA) for task completion. There are, however, often critical limitations in development of SA, which are projected to have a magnified effect when operators must task and control multiple unmanned systems. In this study, we investigated the effects the mode of robot control on operator performance and ability to develop SA while navigating two robots through two mazes. Participants were randomly assigned to groups to control the robots in serial (one after another) or in parallel (at the same time) either manually or using two types of automation. The participants also viewed a systems interface to monitor the status of the robots. Results indicate that participants under serial control produced higher SA scores, th...

Supporting Situation Awareness of Individuals and Teams Using Group View Displays

Abstract: This paper describes a project to design and test a large wall-mounted group view display intended to support situation awareness of individuals and multi-person teams in an advanced power plant control room. The design process began with an analysis of the requirements for situation awareness of individuals and teams to establish the design basis. A function-based cognitive task analysis was then used to define the plant state information to be included in the group view display. A phased test program was then initiated to establish the adequacy of the design concept. The first study employed sequences of static displays representing “snapshots” of evolving normal and emergency events. The second study tested dynamic group view displays (three 100 inch wall mounted displays) driven by a high-fidelity plant simulation. The study compared operator performance with the function-based group view display to operator performance using a more traditional physical mimic overview display. Dependent measures inclu...

Collaborative automation systems for enhancing airport surface traffic efficiency and safety

Abstract: Airport congestion constitutes a key traffic capacity problem in the national airspace system. This paper considers a concept for improving the surface operations at major airports through the use of automation to manage the complex traffic. The concept includes advanced surface-traffic-control automation and flight-deck automation, and it builds on advanced communication, navigation, and surveillance technologies to achieve a seamless integration of these two major components. The surface-traffic-control automation is based on the ground-operation situation awareness and flow efficiency (GO-SAFE) concept previously proposed and studied to enable more efficient usage of runways, especially in situations where active-runway crossing constitutes a significant taxi delay problem. To help achieve the potential GO-SAFE benefits, the flight-deck automation for reliable ground operation (FARGO) concept is proposed to provide the necessary flight-deck automation for enabling precision taxi control to comply with GO-SAFE advisories. The integrated system with highly coordinated automation systems will push the envelope of surface traffic performance to enhance capacity without compromising safety and taxi performance.
