By wireless connection with the remote controller 4, a remote operation from the remote controller 4 is detected, and this detection result is transmitted to the microcomputer 17.

When the microcomputer 17 detects a remote operation from the remote controller 4, the microcomputer 17 clears the currently measured timer time,
From the beginning, the setting timer 15A and the warning timer 15
The timer B resumes the timer operation.
Since the remote controller 4 is to be carried by the person to be monitored, a pendant type hanging from the neck of the person to be monitored or a wristband type to be wound around the arm of the person to be monitored is desirable.

The warning notice buzzer 11C has a setting timer 1
If the withdrawal of the monitored person from the bathroom A is not detected by 5 minutes before the time-up time of 5A, a warning sound is output as a sound, and the monitored person in the bathroom A outputs this warning sound. Can be recognized five minutes before the start of the alarm.

If the leaving time of the monitored person from the bathroom A is not detected by the time before the set time (timer time) expires, the alarm is turned on and output. It is possible to recognize the occurrence of an abnormality of the monitored person in the bathroom A.

That is, the microcomputer 17 sets the setting timer 1
When the set time of 5A is set to 30 minutes, when the entry detection sensor 2 detects entry into the bathroom A, the timer 15A for setting is started, and the set time is set to 25 through the timer monitoring unit 16. If the exit detection sensor 3 does not detect exit from the bathroom A before the elapse of the minute, the alarm advance buzzer 11C through the notification drive unit 14 at the same time as the set time set by the advance alarm timer 15B has expired.
Is output, and the set time is 30 minutes.
If the exit detection sensor 3 does not detect exit from the bathroom A before the elapse of the minute, the alarm indicator 11D is displayed and output through the notification drive unit 14.

Further, in the microcomputer 17, when the entrance detection sensor 2 detects entry into the bathroom A, the microcomputer 17 does not accept the detection result from the exit detection sensor 3 within, for example, one minute after the detection. Bathroom A in the monitored person
The operation at the time of entering the room is compensated, and the malfunction such as detecting the exit of the monitored person from the room even when the room is entering is surely prevented.

Next, the operation of the occupancy management device 1 according to the present embodiment will be described.

FIG. 4 is a timing chart showing the monitoring status of the microcomputer 17 in the normal state, FIG. 5 is a timing chart showing the monitoring status of the microcomputer 17 in the event of an abnormality, and FIG. 5 is a timing chart showing the monitoring status of the monitoring.

The normal state shown in FIG. 4 is an operation state when the monitored person leaves the bathroom A before the timer time expires.

In FIG. 4, the microcomputer 17 starts the timer operation of each of the setting timer 15A and the advance warning timer 15B at the timing t1 when the monitored person enters the bathroom A through the entrance detecting sensor 2. .

The microcomputer 17 monitors the time counting operations of the setting timer 15A and the advance warning timer 15B through the timer monitoring unit 16, and until the time t2 when the timer time currently being counted exceeds 25 minutes, for example, at the time t3. When the monitored person exits from the bathroom A through the exit detection sensor 3 at the time, it is determined that the monitored person has safely exited from the bathroom A, and the setting timer 15A and the warning timer 15B are respectively provided. Is stopped to return to the initial state, and the sound output of the warning notice buzzer 11C and the lighting output of the warning lighting unit 11D are not performed.

As described above, according to the occupancy status management device 1,
If the monitored person safely exits the bathroom A on time, the monitoring load can be reduced by not outputting any of the warning notice buzzer 11C and the warning lighting unit 11D.

The time of occurrence of the abnormality shown in FIG. 5 indicates that the monitored person is in the bathroom A even though the timer time has expired.
This is an operation state when the user does not leave the inside.

In FIG. 5, the microcomputer 17 starts the respective timer operations of the setting timer 15A and the warning alarm timer 15B at the timing t1 when the entry of the monitored person into the bathroom A is detected through the entry detection sensor 2. I do.

The microcomputer 17 monitors the time counting operations of the setting timer 15A and the warning timer 15B through the timer monitoring unit 16, and detects the setting timer 15A without detecting the exit from the bathroom A through the exit detection sensor 3. Timing t2 at which the set time currently being counted exceeds 25 minutes
Then, the warning notice sound is output from the warning notice buzzer 11C through the notification drive unit 14 by voice. That is, the monitored person in the bathroom A starts the alarm with the warning sound of the warning buzzer 11C.
Minutes ago can be recognized.

The microcomputer 17 further includes a timer monitor 1
6, the timer operation of the setting timer 15A is monitored, and without detecting the exit from the bathroom A through the exit detection sensor 3, at the timing t4 at which the currently measured timer time elapses 30 minutes, through the notification drive unit 14. Warning indicator 1
An alarm is lit and output from 1D. That is, the monitoring person can recognize the occurrence of the abnormality of the monitored person in the bathroom A by the lighting display of the warning indicator lamp 11D.

Further, even if the microcomputer 17 detects the exit from the bathroom A through the exit detection sensor 3 after the set time has elapsed, the microcomputer 17 continues to output the sound of the warning notice buzzer 11C and the lighting output of the alarm display lamp 11D. I do.

Then, after the time-up, the microcomputer 17 uses the notification drive unit 14 at the timing t5 to detect the pressing operation of the reset button 12A.
Stop D.

Therefore, the occupancy status management device 1 turns on the alarm display lamp 11D only when it is not possible to detect that the monitored person has left the bathroom A even though the time is up. As a result, the monitoring burden on the monitor can be greatly reduced.

When the timer time is extended as shown in FIG.
Operating state when the set time currently being timed is extended in accordance with a remote operation from the remote control 4 carried by the monitored person when the monitored person within the monitor wants to stay in the bathroom A longer than the normal set time It is.

In FIG. 6, the microcomputer 17 starts the time counting operation of each of the setting timer 15A and the advance warning timer 15B at the timing t1 when the entry of the monitored person into the bathroom A is detected through the entry detection sensor 2. I do.

The microcomputer 17 monitors the timer operation of the setting timer 15A and the advance warning timer 15B through the timer monitoring unit 16, and does not detect the exit from the bathroom A through the exit sensor 3 without detecting the timer currently being counted. At a timing t2 at which the time elapses 25 minutes, an alarm announcement sound is output from the alarm announcement buzzer 11C through the notification drive unit 14 as sound. That is, the monitored person in the bathroom A can recognize the warning warning sound of the warning warning buzzer 11C five minutes before the start of the warning.

The microcomputer 17 does not detect the exit from the bathroom A through the exit detection sensor 3, and controls the remote controller of the monitored person via the wireless communication interface unit 13 before the timing when the currently set time exceeds 30 minutes. At a timing t6 when the remote operation from the remote controller 4 is detected, the set time currently being measured is cleared, the timekeeping operation of the set time is started again, and the sound output of the warning notice buzzer 11C through the notification drive unit 14 is stopped.

The microcomputer 17 monitors the time counting operation of the timer time through the timer monitoring unit 16, and when the microcomputer 17 detects the exit from the bathroom A through the exit detection sensor 3 within the currently measured timer time, for example, at the timing t 7, the setting is performed. The timer operation of the timer 15A and the warning timer 15B are stopped and returned to the initial state, and it is determined that the monitored person has safely exited from the bathroom A, and the warning notice buzzer 11C
And the lighting output of the alarm lighting unit 11D is not performed.

As described above, according to the occupancy status management device 1,
The timer time currently being measured can be extended by remote control of the monitored person in the bathroom A from the remote controller 4.

As described above, according to the present embodiment,
When the entrance detection sensor 2 detects entry into the bathroom A,
The timer operation of the setting timer 15A and the warning timer 15B is started, and the exit sensor 3 does not detect the exit from the bathroom A before the set time set by the setting timer 15A elapses. In other words, it is determined that an abnormality of the monitored person in the bathroom A has occurred only when the exit from the bathroom A has not been detected even though the set time has elapsed. And the warning indicator 11
D can be lit and output, and the monitoring load on the monitoring person who receives the notification can be significantly reduced, and the monitoring target can be reliably prevented from being left in the bathroom A for a long time.

According to the present embodiment, when a remote operation from the remote controller 4 carried by the monitored person is detected, the currently set time is cleared, and the operation of measuring the set time is started again. Thus, the set time currently being counted can be extended, and the monitored person can stay in the bathroom A longer than the normal set time without being warned.

In the present embodiment, the exit detection sensor 3 is constituted by a mat sensor. However, the exit detection sensor 3 is disposed at a detection section for detecting the power ON / OFF operation of the interior light of the bathroom A or at the exit. The exit from the bathroom may be detected by a pyroelectric sensor or the like. Similarly, the entry detection sensor 2 may be realized not only by the pyroelectric sensor but also by various sensors, a mat sensor, an infrared sensor, and an ultrasonic sensor. It goes without saying that you can do it.

Further, in this embodiment, if the leaving time from the bathroom is not detected even though the set time is up, the alarm indicator lamp 1 is issued to notify an alarm.
Although the 1D is illuminated and displayed, a method of outputting an alarm sound as a sound or performing a call operation to an emergency center by connecting to a communication line to notify an alarm to the emergency center may be adopted. It goes without saying that a similar effect can be obtained.

In this embodiment, when a remote operation of the remote controller 4 is detected, the set time is cleared, and the operation of measuring the set time is started again, thereby extending the set time currently being measured. However, the set time currently being measured may be extended in a predetermined time unit, for example, in 5 minute units.

In the present embodiment, the predetermined room as the room to be monitored has been described as the bathroom A, but it is needless to say that the same effect can be obtained even if the predetermined room is used as a toilet.

Further, in the present embodiment, the occupancy status management device 1 may have a two-circuit configuration so as to simultaneously monitor the bathroom and the toilet.

[0060]

As described above, according to the occupancy status management apparatus of the present invention, when the entry detection means detects entry into a predetermined room, the timer means starts a time counting operation, and Before the set time elapses, the exit detection means does not detect exit from the predetermined room, that is, it is not possible to detect exit from the predetermined room even though the set time has elapsed. Only in this case, it is determined that an abnormality has occurred in the monitored person in the predetermined room, and the notification operation of the notification unit can be started.

For this reason, it is possible to reliably prevent the monitored person from being left in the predetermined room for a long time while greatly reducing the monitoring burden on the monitored person receiving the notification.
