Description

The present disclosure relates to a monitoring technology for bathrooms and the like that detects and reports abnormalities of bathers and the like.

There is no end to accidents while taking a bath. In the event of an abnormality, it is practically difficult for the bather to notify himself outside the bathroom. Aside from being accompanied by a caregiver, the bathroom usually respects the privacy of the bather, which is a problem. Even if you care about the bather outside the bathroom, there is a limit to constantly monitoring the bather from outside the bathroom while taking a bath.
Regarding the detection of abnormalities in bathers, it is known that a motion sensor is attached to the bath remote control in the bathroom to issue an alarm when an abnormality such as the position, posture, or fall of the bather is detected, and to notify the outside by communication means.

The opening and closing of the bathroom door 6 (B in FIG. 8) is opened and closed by, for example, the bather 8, B1 indicates an open / closed state for entering the room, B2 indicates an open / closed state for entering the room, and B3 indicates an open / closed state for leaving the room. ..
The sound collection information (C in FIG. 8) includes an opening / closing sound C1, a background sound C2, an operation sound and a shower sound C3, a shower sound C4, a background sound C5, and an opening / closing sound C6. The opening / closing sounds C1 and C6 are sounds indicating the opening / closing of the bathroom door 6. The background sounds C2 and C5 are sounds that do not involve the movement of the bather 8. The operation sound / shower sound C3 is a mixed sound of the operation sound representing the operation of the bather 8 and the running water sound due to the shower running water. Shower sound C4 is only the sound of running water from the shower.

The event information (D in FIG. 8) includes event information D1, D2, D3, D4, D5, and D6. Event information D1 and D6 indicate an opening / closing event of the bathroom door 6, and D3 is an operation event including the bather 8. For example, an operation event of the bather 8 who operates the shower plug 16 to bathe in running water is indicated. On the other hand, D2, D4, and D5 do not have event information, and a state change occurs between D4 and D5 at the moment when the shower sound ends, and event information is generated.
Therefore, in the state determination (E in FIG. 8) using this event information, the determination result is that the non-stationary states E1, E3, E6 are in the period in which the event exists, and the steady states E2, E4, E5 are in the period in which the event does not exist. Is obtained.

For example, "pattern A", "pattern B", "pattern C", ... Are stored in the pattern unit 62 as identification information of the detection pattern.

The analysis information unit 64 stores the analysis information which is the analysis result from the sound collection information. This analysis information includes sound information representing an analysis result such as "non-steady sound", "steady sound", and "loud sound above a threshold level". The “unsteady sound” is a sound that changes with time and represents the movement of the bather 8. The "steady sound" is a sound representing a time-dependent state in which the sound does not change for X seconds or more for the duration described above. That is, it is not the operating sound of the bather 8, but the background sound that does not change, such as a continuous shower sound. Further, the "loud sound above the threshold level" is a sound representing an unexpected state such as a fall of the bather 8.
The state determination unit 66 stores determination information representing the determination result by the processing unit 34. There are unsteady state (= normal) and steady state (= abnormal) in this determination result.

Therefore, the following abnormality detection results are presented in the abnormality detection logic table 60.
In pattern A, “non-steady sound” is obtained from the sound collection information, and the non-steady state, that is, the bather abnormality is not detected.
In pattern B, a "steady sound" is obtained from the sound collection information, and a steady state, that is, an abnormality in the bather is detected.
In pattern C, "a loud sound equal to or higher than the threshold level" is obtained from the sound collection information, and a steady state, that is, an abnormality of the bather is detected.

(4) The microphone 38 is used to collect the sound in the bathroom 2 with high sensitivity, and the sound collection information can be acquired to monitor the behavior of the bather 8.
(5) Abnormality detection of bather 8 is premised on the movement of bather 8 and the presence of background sound. When bather 8 has movement, it is in an unsteady state (= normal or absent), and when there is no movement, it is in a steady state. Since it is determined to be (abnormal), the abnormality of the bather 8 can be detected easily and with high accuracy.
(6) Since a call is made to the bather 8, the bather 8 can respond to the call, and if there is no response, after a lapse of a predetermined time, an abnormality is detected from the outside by a call outside the bathroom, and an unexpected situation occurs. It can be avoided.
(7) In the conventional human detection using a human detection sensor, if a noise component is included in the element that triggers the judgment of normality / abnormality, a malfunction or a false judgment occurs, but the human movement is sounded. Since it is detected by, it is possible to construct an excellent detection system that suppresses malfunctions.
(8) When monitoring with a camera, image processing becomes large in order to avoid compromising privacy, and there is a problem that it is difficult for the observer to make a judgment. However, such inconvenience can be avoided by the abnormality detection of the present disclosure. ..
