MONITORING SYSTEM

摘要

A monitoring device of a monitoring system includes a control, an alarm, a first sensor for detecting motion higher than a first predetermined height, a second sensor for detecting, on a floor of a building, motion lower than a second predetermined height, and a third sensor means for detecting an arrival in a sleeping place and a departure from the sleeping place. When the most recent motion detection fed by the third sensor to the control is the arrival in the sleeping place, the control controls the alarm to give an alarm if a predetermined first delay, beginning at the arrival in the sleeping place, is filled before information about the departure from the sleeping place has been received from the third sensor. After the third sensor has detected the departure from the sleeping place, the control controls the alarm to give an alarm if the control receives no motion detections from the first sensor and the second sensor during a predetermined second delay.

1. A monitoring system for monitoring a person in a building, wherein a monitoring device of the monitoring system comprises control means comprising information on a location permitted at a given time to the person in the building, alarm means, first sensor means for detecting motion higher than a first predetermined height, second sensor means for detecting, on a floor of the building, motion lower than a second predetermined height, and third sensor means for detecting an arrival in a sleeping place and a departure from the sleeping place;
when the most recent motion detection fed by the third sensor means to the control means is the arrival in the sleeping place, the control means are configured to control the alarm means to give an alarm if a predetermined first delay, beginning at the arrival in the sleeping place, is filled before information about the departure from the sleeping place has been received from the third sensor means; and after the third sensor means have detected the departure from the sleeping place, the control means are configured to control the alarm means to give an alarm if the control means have received no motion detections from the first sensor means and the second sensor means during a predetermined second delay.
