Distribution of audible notifications in a control room
First Claim
1. A method for delivering an audible notification from a process control system to an operator in a control room environment by one or more first speakers having a first coverage for audible notifications and one or more second speakers having a second coverage for audible notifications, wherein the one or more first speakers constitute a directional speaker, the second coverage is different from the first coverage and configured to overlap and cover the complete first coverage, and wherein the audible notification is an alarm, the method comprises:
- sensing the presence or absence of the operator in one or more zones of the control room environment,determining if the location of the operator is covered by the first coverage based on the sensing,delivering the audible notification by the one or more first speakers if it is determined that the location of the operator is covered by the first coverage, anddelivering the audible notification by the one or more second speakers if it is determined that the location of the operator is not covered by the first coverage.

Abstract
A technology for delivering an audible notification from a process control system in a control room environment, where the delivery is made by one or more first speakers having a first coverage for audible notifications and one or more second speakers having a second coverage for audible notifications. A determination if the location of an operator is covered by the first coverage is made. The audible notification is delivered by the one or more first speakers if it is determined that the location of the operator is covered by the first coverage. The audible notification is delivered by the one or more second speakers if it is determined that the location of the operator is not covered by the first coverage.

9. A system for delivering an audible notification from a process control system to an operator in a control room environment, wherein the audible notification is an alarm, the system comprises:
-
one or more first speakers having a first coverage for audible notifications, wherein the one or more first speakers constitute a directional speaker, one or more second speakers having a second coverage for audible notifications, wherein the second coverage is different from the first coverage and configured to overlap and cover the complete first coverage, a detector for sensing the presence or absence of the operator in one or more zones of the control room environment, and a processor configured to; determine if the location of the operator is covered by the first coverage (56) based on a sensing by the detector, deliver the audible notification by the one or more first speakers if it is determined that the location of the operator is covered by the first coverage, and to deliver the audible notification by the one or more second speakers if it is determined that that the location if the operator is not covered by the first coverage. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A computer program product for use in a system comprising one or more first speakers having a first coverage for audible notifications, one or more second speakers having a second coverage for audible notifications, wherein the second coverage is different from the first coverage and configured to overlap and cover the complete first coverage, and a detector for sensing the presence or absence of the operator in one or more zones of the control room environment, wherein the one or more first speakers constitute a directional speaker and the audible notification is an alarm, the computer program product comprising program code instructions configured to, when executed by a processor of the system, cause the processor to:
-
determine if the location of the operator is covered by the first coverage based on a sensing by the detector, deliver an audible notification by the one or more first speakers if it is determined that the location of the operator is covered by the first coverage, and deliver the audible notification by the one or more second speakers if it is determined that the location of the operator is not covered by the first coverage. - View Dependent Claims (18)
