Abstract

This disclosure relates to an automatic alert system using a set of small sensors. This system can detect if the target person is working in the Data Processing (DP) room. The system detects this by motion detecting sensors and infrared human sensors outputs Set both Infrared Human Sensor (IHS) and Infrared Motion Sensor (IMS). Motion sensor detects the derivative of infrared distribution. Once IHS detects a human, it starts the IMS counter of same location. When IMS detects motion, it resets the counter. If the counter value becomes, for example, 15 seconds, the system issues an alert. If a human is detected but no motion is detected for the person, the system judges that the person is sick or sleeping. When an operator becomes sick, the operator will not move.

Human Behavior Detection Using a Set of Sensors

      This disclosure relates to an automatic alert system using a
set of small sensors.  This system can detect if the target person is
working in the Data Processing (DP) room.  The system detects this by
motion detecting sensors and infrared human sensors outputs Set both
Infrared Human Sensor (IHS) and Infrared Motion Sensor (IMS).  Motion
sensor detects the derivative of infrared distribution.  Once IHS
detects a human, it starts the IMS counter of same location.  When
IMS detects  motion, it resets the counter.  If the counter value
becomes, for example, 15 seconds, the system issues an alert.  If a
human is detected  but no motion is detected for the person, the
system judges that the person is sick or sleeping.  When an operator
becomes sick, the operator  will not move.  Therefore, the TV camera
base system does not work to find out what is happening.  This system
improves it.
