Abstract

Context based information visualization is preferred to deal with information overload in a control room environment. A well developed intuitive visualization solution has tremendous potential for the operator as a tool for effective management of emergency/ alarm situations and efficient management of regular activities. The invention description describes some use cases for context based information visualization for Automation systems.

Context based Dynamic HMI for Automation Systems

1.0 Background(problem description)

Context based information visualization is preferred to deal with information overload in a control room environment. A well developed intuitive visualization solution has tremendous potential for the operator as a tool for effective management of emergency/ alarm situations and efficient management of regular activities.

Though, there is no doubt that context based information rendering is beneficial, there are issues in whole heartily adapting this approach. The primary technical issue may be related to the risk of performance degradation from computationally intensive operations for context based data manipulations. There is also an issue with definition of context itself and the mechanism to link it with the data/information. The common way to establish this link is through use of filters. For example the data/information may be filtered based on role, situation etc. The choice of technology for rendering display along with the means of display system (control room/hand held devices, thick/thin clients etc) are yet another aspect that could be considered in definition of context as these has bearing on performance (quality) and size (quantity) of information. This choice becomes critical to mitigate the risk of lock-in to a particular user interface technology (eg Silverlight, Adobe Air etc) and device specific development. The non-technical issue may be the lock-in resulting from inability/ lack of desire to introduce new visualization methods due to habit / preference of already existing and functional practices/methods.

The present day automation system, offers role based information system and has support to render information to remote/thin client systems. However, these information are static in nature i.e. the information style are preconfigured and for this reason suffer from being not able to provide relevant information to the user or suffer in times when there is a lot of information, unable to provide required or useful information due to information overload. The invention describes scenarios and means to have auto-configurable information system to meet situational needs arising in an automation industry.

2.0 Invention Description

A pre-selected number of situations or operator needs are analyzed for a specific industry in terms of who needs what information to carry out what operation using what device. It may be evident that this approach would provide countable instances of context for the specific industry.

A typical means to store context based information and render is through use of a vector comprising a set (matrix) of attribute definitions based on role, situation, access device etc. Definitions in the form of matrix are easily config...
