Process plant control desks utilising Human-Computer Interfaces
|Publication Date:||1 March 2010|
This Publication relates to Human-Computer Interface (HCI) systems provided for people operating industrial processes and activities on facilities such as chemical plant, power stations, oil refineries, etc. It gives guidance on:
• the factors to take into account when designing an HCI for such processes and activities;
• display hierarchies;
• screen display format design; and
• control room design attributes which affect HCI.
The objective is to help engineers and design teams develop HCI systems which are more usable and therefore result in safer and more cost-effective operation of industrial systems. The Guide is also intended to help reduce the need for reengineering of systems after installation.
Both batch and continuous processes are covered by this Guide.
HCI systems form the essential operator interface to large modern industrial systems. They are utilised in power stations, refineries, chemical plants (both batch and continuous), utility distribution centres and many other places. They provide the vital means by which the operator obtains information on the state of the plant, enters operational parameters, and by which any automatic control action can be overridden and manual control of the plant be taken.
The purpose of this Guide is to help those involved in the design, procurement, operation, maintenance, management, assessment and review of these systems. It is intended to help both improve existing systems and develop new facilities during plant construction. It is for use by engineers and managers in both user and contracting organisations. The objective is not only to make plants more operable, efficient and able to avoid abnormal situations, but to be able to better manage such situations should they occur.
This Guide has been written and widely reviewed by users in industry and is based on what some leading companies are doing. The guidance is designed to be practical and usable. The general guidance is directed towards large sophisticated computer-based process systems, but also contains much general information on HCI.
