PROBLEM TO BE SOLVED: To provide a bathroom emergency situation detection system which easily detects such a situation that a person falls down in a bathroom.SOLUTION: A bathroom emergency situation detection system includes: a door sensor 12 for sensing the opening/closing of a door 13 of a bathroom; and two or more Doppler sensors 11 for detecting a movement on an inside 10 of the bathroom. An analysis of data of the Doppler sensors 11 is started from the initial state by using the opening/closing of the door 13 as a start trigger, which is sensed by the door sensor 12. During the analysis, a body movement of a person 15 on the inside 10 of the bathroom is detected by the Doppler sensors 11. If such a state that a value of the body movement to be detected becomes equal to or less than a reference value is kept for a predetermined time during the analysis, an alarm issuing process is performed. Then, the analysis is completed by using the second opening/closing of the door 13 as an end trigger.SELECTED DRAWING: Figure 1 |
