IT vs. AV Approach to Large-Scale Visualization
Large-scale visualization has traditionally been considered an audio-visual (AV) component of control room design, due to the large-sized and/or large amounts of connected display components typically utilized. However, advances in IT technology and the power of the network are resulting in a shift from AV to IT based visual information distribution within the control room and beyond: from a circuit switched to a packet switched architecture.
Evolution of Control Room Visualization
There have broadly been two stages in the evolution of large-scale control room visualization, with a third stage currently emerging that should significantly increase the utility value and operational effectiveness of control room visualization. Within this stage, agency solutions will be integrated with and driven by monitoring and analytical software. This added integration allows critical visual information or a full common operating picture to be automatically pushed to other sites, to the field, and up the command based on incident alarms and triggers.
Matrixed Display Technology
This white paper identifies and analyzes matrixed display technologies that are suitable for large-scale data and video display in a control room environment. This paper identifies their strengths and weaknesses and suggests a decision making methodology to select the appropriate display technology for a given environment.
Optimal Character Size
This paper explores the minimal optimal character size to use for text and numerical data for large-scale display based on viewing distance, and the appropriate font size to use when creating or formatting custom content.
Transitioning to a Smart Grid
The control room is the nerve center for grid management in the electric utility market. The information display system functions as a window into how everything is working. The right kind of information display system can either help or hinder compliance with the new CIP regulations and a utility’s Smart Grid initiative. Download our whitepaper examining critical issues emerging from the FERC Smart Grid “Proposed Policy Statement and Action Plan,” which has direct implications to a control room’s information display system.
Visual Space
Visual space and visual resolution are two important concepts to consider when designing effective information displays in control rooms. Understand how to calculate the optimal distance at which the pixel size and operator’s visual acuity are perfectly matched.
