Safety device for a technical installation or a technical process
First Claim
1. A safety device having a processor for detecting and evaluating the degree of attention of an operator of a technical installation or a technical process, the safety device comprising:
- a first module configured to;
record values of predefined physiological parameters of the operator and determine a first characteristic number from the recorded values; and
compare the determined first characteristic number with a predefined first characteristic value and, if the first characteristic value is exceeded and/or undershot or if a predefined first range of characteristic values is left, activates a second module; and
wherein the second module is configured to;
record further values provided by a checking or triggering mechanism;
determine a second characteristic number for the degree of attention of the operator from the recorded further values;
compare the second characteristic number with at least one second predefined characteristic value and, if the second characteristic value is exceeded and/or undershot or if a predefined second range of characteristic values is left; and
request an action from the operator, and if the operator does not respond to the request, triggers an activation module for taking countermeasures which increases the attention of the operator of the installation, the countermeasures including automatically informing a further person of the operator'"'"'s failure to respond to the request.

Abstract
The disclosure relates to a safety device and a method for detecting and evaluating the degree of attention of an operator of a technical installation or a technical process, which includes a first module which records values of predefined physiological parameters of the operator and determines a first characteristic number from the recorded values, compares the determined first characteristic number with a predefined first characteristic value, which activates a second module which records further values provided by a checking or triggering mechanism. The second module determines a second characteristic number for the degree of attention of the operator from the recorded further values, compares the second characteristic number with at least one second predefined characteristic value, which triggers an activation module in order to take countermeasures which increase the attention of the operator of the installation.

11. A method for a technical installation or a technical process using a device for detecting and evaluating the degree of attention of an operator of the installation or the process, the method comprising:
-
recording values of predefined physiological parameters of the operator using a first module; determining a first characteristic number from the recorded values; comparing the determined first characteristic number with a predefined first characteristic value and, if the first characteristic value is exceeded and/or undershot or if a predefined first range of characteristic values is left, activating a second module to record further values provided by a checking or triggering mechanism; determining a second characteristic number for the degree of attention of the operator from the recorded further values using the second module; and comparing the second characteristic number with at least one second predefined characteristic value and, if the second characteristic value is exceeded and/or undershot or if a predefined second range of characteristic values is left, requesting an action from the operator and if the operator does not respond to the request, triggering an activation module for taking countermeasures which increase the attention of the operator of the installation, the countermeasures including automatically informing a further person of the operator'"'"'s failure to respond to the request. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
