Description

The present invention relates to a bathroom monitoring system capable of detecting infants and animals that have entered the bathroom.

Conventionally, a motion sensor that detects people by radio waves is installed on the wall or ceiling of the bathroom to detect infants who have entered the bathroom or suspicious persons who are trying to enter the bathroom from the outside, and notify them with an alarm. It has been known.

For example, the abnormality detection device of Patent Document 1 is composed of a first sensor and a second sensor. The first sensor is installed on the wall surface of the bathroom and detects the movement of people in the entire bathroom. In addition, the second sensor is installed in the dressing room and detects the movement of a person with a height of 1 m or more.

Then, when the second sensor does not detect the movement of a person in the dressing room and the first sensor detects the movement of a person in the bathroom, it reports an abnormality as a possibility that an infant has entered the bathroom. (Patent Document 1 / paragraphs 0013 to 0015, FIG. 1).

Japanese Unexamined Patent Publication No. 2006-065367

However, in the above-mentioned abnormality detection device, when the infant enters the dressing room with his / her hand raised, the second sensor is turned on first, and then when the infant enters the bathroom, the first sensor is activated. Since it is turned on, it was not judged to be abnormal. For this reason, it was not possible to reliably detect and report the entry of the infant into the bathroom.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a bathroom monitoring system capable of more reliably detecting and notifying a specific living body such as an infant who has entered the bathroom. To do.

In the bathroom monitoring system of the present invention, when the physiological amount detecting unit that detects the physiological amount of the living body entering the bathroom and the physiological amount detected by the physiological amount detecting unit are within a preset determination range. The determination range setting unit includes an entry notification unit that notifies the user and a determination range setting unit that sets the determination range. It is characterized in that the type of the living body or the age of the living body is specified based on the physiological amount detected by the physiological amount detecting unit, and the determination range is set .

In this bathroom monitoring system, the physiological amount detection unit detects the physiological amount (heart rate, respiratory rate, etc.) of the living body to be notified while the living body is in the bathroom. Then, the determination range setting unit specifies the type of the living body or the age of the living body based on the detected physiological amount, and sets the determination range. For example, the heart rate of the child is, because in the higher value range as compared to adults, when physiological in living in the bathroom is in the preset determination range, entry notification unit performs notification. As a result, it is possible to realize a bathroom monitoring system capable of more reliably detecting and notifying a specific living body such as an infant who has entered the bathroom.

Further, in the bathroom monitoring system of the present invention, before Symbol physiological quantity detecting unit is provided in the installed bath heater in the bathroom, the determination range setting unit, the bathroom heater by different user and the biometric It is preferable to execute the process of setting the determination range according to the operation of the operation unit of.

According to this configuration, when the user operates, for example, the operation unit (remote control) of the bathroom heater outside the bathroom, the determination range setting unit is set to the living body (bathroom) to be notified. It is possible to execute a process of setting a judgment range of the physiological amount of an infant living in a house, etc.).

Further, in the bathroom monitoring system of the present invention, it is preferable that the physiological amount detection unit detects any one of the heartbeat, pulse, respiration, and blood pressure of the living body as the physiological amount.

Heart rate, pulse, respiration, and blood pressure have different numerical ranges depending on the age of human beings or whether they are humans or animals. Therefore, by detecting the state as the physiological amount detected by the bathroom monitoring system, the living body that has entered the bathroom can be easily identified.

An embodiment of the present invention will be described with reference to FIGS. 1 to 5. The bathroom monitoring system 1 is configured as a part of the function of the bathroom heater 10 described later. First, the bathroom BR, which is the monitoring area of the bathroom monitoring system 1 of the present invention, will be described with reference to FIG.

A bathtub 2, a bathroom remote controller 3, and a bathroom heater 10 are installed in the bathroom BR. The bathroom remote controller 3 is installed on the wall surface of the bathroom BR, and can remotely control the water heater 30 installed outdoors.

Further, the bathroom heater 10 is installed on the wall surface of the bathroom BR. The bathroom heater 10 has a function of air-conditioning the bathroom BR (heating, ventilation, drying, ventilation, etc.), and is remotely controlled by a bath warming remote controller 20 installed on the wall surface of the dressing room DR adjacent to the bathroom BR. .. The installation location of the bathroom heater 10 may be the ceiling of the bathroom.

The bathroom heater 10 is communicatively connected to the water heater 30, and is also remotely controlled by the bathroom remote controller 3 and the kitchen remote controller 40 which is installed in the kitchen and remotely controls the water heater 30. The bathroom remote controller 3 and the kitchen remote controller 40 are provided with a display and a speaker for notifying the operating state of the water heater 30 and the like.

Further, the bathroom heater 10 includes a physiological amount sensor 12 (corresponding to the “physiological amount detecting unit” of the present invention). The physiological amount sensor 12 is, for example, a Doppler sensor that irradiates a human body with microwaves and senses the difference between the irradiated wave and the reflected wave, and does not contact the heart rate of the intruder P who has entered the bathroom BR. Can be detected with. The physiological amount sensor 12 may be provided outside the bathroom heater 10 and may be wiredly connected to the bathroom heater 10.

Since the average value of the heart rate differs depending on the age of the human being, it is possible to determine who the intruder P or the bather is in the family based on the heart rate detected by the physiological amount sensor 12. it can. Since there are differences in heart rate between humans and animals (pets such as dogs and cats), it is possible to distinguish between them.

Normally, the entrant P enters the bathroom BR from the dressing room DR through the bathroom door 4. The bathroom monitoring system 1 detects the heart rate of the intruder P and determines that the heart rate is set in advance in order to prevent an accident such as an infant entering the bathroom BR alone and falling into the bathtub 2. When it is within the range, a warning sound or the like is output from the speakers of the kitchen remote control 40 and the bathroom remote control 3, and a warning screen is displayed on the display to notify the user.

The notification by the bathroom remote controller 3 has the effect of not only notifying the adult near the bathroom BR but also directly warning the infant who has entered the bathroom BR. The warning is not limited to the bathroom remote controller 3 and the kitchen remote controller 40, but can also be issued by the bath warming remote controller 20.

Next, the overall configuration of the bathroom monitoring system 1 will be described with reference to FIG.

First, the bathroom heater 10 includes a remote control communication circuit 11 that communicates with the bath warming remote controller 20 via a remote controller, a physiological amount sensor 12 that detects the heart rate of a person in the bathroom BR, and a bathroom heater 10. Communication connected to the communication network 60 via the bathroom heating control unit 13 that controls the overall operation, the water heater communication circuit 14 that communicates with the water heater 30, and the wireless router 50 installed outdoors. It is provided with an external communication circuit 15 that communicates with a terminal 70 (smartphone, mobile phone, tablet terminal, etc.). The device connected to the communication network 60 may be a television connected to the Internet.

The bathroom heating control unit 13 is an electronic unit composed of a CPU, a memory, various interface circuits, and the like. By executing a control program of the bathroom heater 10 held in the memory by the CPU, the bathroom heater 10 It functions to control the operation. Further, the bathroom heating control unit 13 includes an entry notification unit 131 for issuing a warning when a specific living body is detected in the bathroom BR, and a determination range setting unit 132 for setting a threshold value and a range of physiological amounts. ing.

Next, the bath warming remote controller 20 has a remote controller communication circuit 21 that communicates with the bathroom heater 10 via a remote controller cable, a bath warming remote controller control unit 22 that controls the overall operation of the bath warming remote controller 20, and The initial setting switch 23 is provided to instruct the start of the process of acquiring the physiological amount serving as the threshold value for warning from a specific living body in the bathroom BR by the process described later (see FIG. 5). Further, although not shown, an operation switch for directly setting a physiological amount as a threshold value, for example, a heart rate of "100 (times / minute)" is also provided.

Next, the water heater 30 includes a bathroom heater communication circuit 31 that communicates with the bathroom heater 10, a water heater control unit 32 that controls the overall operation of the water heater 30, and a bathroom remote controller 3 or a kitchen remote controller. A remote control communication circuit 33 for communicating between the 40s via a remote control cable is provided.

For example, when an infant enters the bathroom BR, the heart rate of the infant is detected by the physiological amount sensor 12 of the bathroom heater 10. Then, it is determined from the numerical value of the heart rate whether or not it is within the determination range in which the bathroom heating control unit 13 gives a warning. When it is determined to give a warning, a signal to that effect is transmitted from the water heater communication circuit 14 to the kitchen remote controller 40 via the bathroom heater communication circuit 31 and the remote controller communication circuit 33 of the water heater 30. As a result, even when the adult is away from the bathroom BR, the warning emitted from the speaker of the kitchen remote controller 40 makes the adult aware of the abnormality in the bathroom BR.

When the bathroom heating control unit 13 determines to issue a warning, a warning message is transmitted from the external communication circuit 15 of the bathroom heater 10 to the communication terminal 70 via the wireless router 50 and the communication network 60 by e-mail or the like. You may.

Next, a flowchart of the physiological amount detection process of the bathroom monitoring system 1 will be described with reference to FIG. In addition, the explanation will be supplemented with reference to the heart rate tables of FIGS. 4A and 4B as appropriate.

First, in STEP 1, the physiological amount sensor 12 determines whether or not a living body is detected in the bathroom BR. The physiological amount sensor 12 may be turned on at all times, or may be turned on from the bath warming remote controller 20 or the kitchen remote controller 40 only when the bathroom BR is not used. If a living body is detected in the bathroom BR, the process proceeds to STEP2, and if not detected, a loop is performed until the detection is performed.

In STEP2, the heart rate of the living body in the bathroom BR is measured by the physiological amount sensor 12. The living body is mainly assumed to be a human being, but a pet such as a dog or a cat may be used, and the heart rate can be measured if the living body has water. Then proceed to STEP3.

In STEP3, it is determined whether or not the measured heart rate is 100 (times / minute) or more, which is a threshold value. According to the heart rate table of FIG. 4A, when the heart rate (average value) is 100 to 120 (times / minute) in the warning range, it corresponds to a human being under 4 years old, and when one person approaches the bathroom BR. It's a dangerous age. Therefore, in the bathroom monitoring system 1, the heart rate of 100 (times / minute) is set as a threshold value.

Further, according to the heart rate table of FIG. 4B, the heart rates of the dog (small dog) and the cat are 180 (times / minute) and 145 (times / minute), respectively, so that the heart rate is 100 (times / minute). By setting to the threshold value, even when a pet enters the bathroom BR, it can be targeted for notification described later. If the heart rate is 100 (times / minute) or more, the process proceeds to STEP4, and if the heart rate is less than 100 (times / minute), the process returns to STEP1.

In STEP4, notification that a specific living body has been detected is started. For example, the buzzer sounds from the speaker of the kitchen remote controller 40, or a warning such as "an infant has entered the bathroom" is issued. Then proceed to STEP5.

Finally, in STEP 5, it is determined whether or not the notification is canceled. For example, an adult takes an infant or pet that has entered the bathroom BR out of the bathroom BR, and cancels the notification with the bath warming remote controller 20 or the like. This process completes a series of physiological quantity detection processes.

This time, the threshold value was set to heart rate 100 (times / minute), but the threshold value can be appropriately changed depending on the family structure. It is also possible to set the heart rate of the infant in the household as a threshold value, which is dangerous if one person enters the bathroom BR.

Next, with reference to FIG. 5, a flowchart of an initial setting process for setting the above-mentioned threshold value to the heart rate of an infant in the home will be described.

First, in STEP 11, an adult turns on the initial setting switch 23 (corresponding to the "operation unit" of the present invention) of the bath warming remote controller 20 with the infant to be notified entered in the bathroom BR. The determination range setting unit 132 (see FIG. 2) starts the setting process of the range or the threshold value of the heart rate to be notified by this operation.

After the initial setting switch 23 is turned on, it takes a predetermined time until the sensing by the physiological amount sensor 12 becomes stable. After that, the process proceeds to STEP12.

In STEP 12, the physiological amount sensor 12 starts the detection of the living body in the bathroom BR. After that, the process proceeds to STEP 13.

In STEP 13, the physiological amount sensor 12 determines whether or not the detection time t of the living body exceeds 10 seconds. If the detection time t exceeds 10 seconds, it is determined that the heart rate can be measured for the living body, the process proceeds to STEP 14, and if it is 10 seconds or less, a loop is performed until it exceeds 10 seconds.

In STEP 14, the heart rate of the living body in the bathroom BR is measured by the physiological amount sensor 12. This makes it possible to measure the heart rate of an infant in the bathroom BR. Then proceed to STEP15.

Finally, in STEP 15, the heart rate measured in STEP 14 (for example, 105 (times / minute)) -α is set as a threshold value. Here, "α" is an adjusted value determined in consideration of the change in heart rate depending on the state of the living body. From the next time, in the physiological amount detection process (see FIG. 3), when the heart rate is 105 (−α) or more, the notification will be performed. This process ends a series of initial setting processes.

The physiological amount may be pulse rate, respiratory rate or blood pressure. Since the pulse rate and the respiratory rate also tend to correspond to the human age, it can be used to determine whether or not to warn by setting a threshold value. In addition, the waveform of respiration may be confirmed to determine whether it is an adult or a child, and a warning may be given.

The physiological amount to be measured is not limited to its absolute value. For example, the physiological amount is measured for a predetermined time to obtain the slope (degree of change) of the change in the physiological amount. Then, if the tendency of the inclination is that of a child, a warning may be given.

Further, the installation location of the physiological amount sensor 12 is not limited to the bathroom BR. A detection area by a physiological amount sensor provided in the dressing room DR (for example, a position where the inside of the bathroom BR can be seen when the bathroom door 4 is opened) is set in the bathroom BR, and the physiological amount of the living body entering the bathroom BR is set. May be detected.
