<P>PROBLEM TO BE SOLVED: To provide an abnormality sensing system capable of surely detecting an abnormality of a resident without requiring switching between "staying at home" and "left home," while suppressing erroneous report. <P>SOLUTION: A safety confirmation system includes: a first sensor for sensing opening/closing of an entrance door; a second sensor for sensing a movement of an object near the entrance door; multiple third sensors for sensing a movement of an object in the house; a determination device connected to these sensors; and an alarm lamp connected to the determination device. The determination device determines that it is a first state when the second sensor senses a movement of an object after the first sensor senses closing of the entrance door, that it is a second state when the first sensor senses closing of the entrance door after the second sensor senses a movement of an object, and that it is the first state when the second sensor and at least one of the multiple third sensors sense a movement of an object even in the second state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
