Description

  The present invention relates to a bathroom management system and a bathroom management program for appropriately controlling a bathroom environment.

In recent years, a technique for appropriately controlling the bathroom environment using fluctuations in heart rate has been proposed. As such a technique, for example, an R wave interval between heartbeats is calculated from a bather's cardiac radio wave, and the R wave interval is subjected to frequency analysis, and a respiratory fluctuation component that is a component up to about 0.08 Hz in the power spectrum. The amount of change in respiratory components is defined as the degree of relaxation at the time of bathing by the bather, and the degree of relaxation is periodically derived. There is a technique of maintaining or decreasing the water flow speed when the degree of relaxation is higher than the previous time (see, for example, Patent Document 1).
JP-A-7-163536

  However, since fluctuations in heart rate do not depend only on external factors such as water flow velocity, other factors can lead to a more uncomfortable bathroom environment. The subject of this invention is providing the bathroom management system which can control a bathroom environment more appropriately.

  The bathroom management system according to claim 1 includes a heart rate measurement device, an R wave interval derivation device, a body motion measurement device, and a bathroom environment control device. The heartbeat measuring device, the R wave interval deriving device, the body motion measuring device, and the bathroom environment control device may be a single device. The heart rate measuring device measures a heart rate. The R wave interval deriving device obtains the R wave interval of the heartbeat. The body movement measuring device measures body movement. The bathroom environment control device controls the bathroom environment using information on the interval between the R waves of the heartbeat and information on body movement. It should be noted that the heartbeat R-wave interval information and the body motion information may be used independently of each other or may be used as calculation parameters for deriving other control parameters. The “bathroom environment” here means, for example, hot water temperature such as a bathtub or shower, water flow speed, quietness of the bathroom, or brightness of the bathroom.

Here, the heart rate measuring device measures the heart rate. Then, the R wave interval deriving device obtains the R wave interval of the heartbeat. Furthermore, the bathroom environment control device controls the bathroom environment using information on the interval between the R waves of the heartbeat.
The interval between the R wave and the R wave seen in the electrocardiogram waveform (hereinafter referred to as the R wave interval) is not constant but constantly fluctuates. Since the heartbeat is antagonized by the autonomic sympathetic nerve and the parasympathetic nerve, it is possible to clarify the activity status of the sympathetic nerve and the parasympathetic nerve by analyzing the fluctuation of the R wave interval of the heartbeat. it can. The sympathetic nerve has a function to activate the body to resist physical and mental loads. On the other hand, the parasympathetic nerve has a function of requesting rest / rest. Specifically, if sympathetic nerves are increased due to physical and mental loads, the heart rate increases and the R wave interval is shortened. For this reason, it can be estimated that it is in a tense state if the R wave interval is shortened, and it can be estimated that the state is relaxed if it is longer. Note that the fluctuation of the R wave interval of the heartbeat is often performed by frequency analysis. When the frequency analysis of the R wave interval is performed, two components having peaks in a low frequency region of 0.04 to 0.15 Hz (hereinafter referred to as LF) and a high frequency region of 0.15 Hz or higher (hereinafter referred to as HF) appear. . The sympathetic nervous system has a characteristic of not transmitting heart rate fluctuations of 0.15 Hz or higher. Therefore, the ratio of LF to HF (hereinafter referred to as LF / HF) is obtained, and when the LF / HF value is high, it can be estimated that the sympathetic nerve is mainly active, and the LF / HF value is low. Sometimes it can be assumed that parasympathetic nerves are mainly active. Therefore, if the bathroom environment is controlled such that the R wave interval of the heartbeat measurement object, for example, the bather becomes long, a comfortable bathroom environment can be provided to the measurement object.

  By the way, the heartbeat fluctuates not only by physical and mental loads but also by body movements. When there is a body motion, the heart rate increases and the R wave interval is shortened. For this reason, when the bathroom environment is controlled using only the heartbeat, the bathroom environment control device receives the physical and mental load when the measurement target moves the body without physical and mental load. There is a risk that the bathroom environment set comfortably will be changed to an unpleasant one. However, here, the body movement measuring device measures the body movement. For this reason, the bathroom environment control device can determine whether the heartbeat is fluctuating due to physical or mental load or fluctuating due to body movement. And a bathroom environment control apparatus controls the environment of the measuring object of a body movement measuring apparatus also using the information of body movement. Therefore, it is possible to eliminate the possibility that the bathroom environment is led from a comfortable person to an unpleasant person. As a result, the bathroom environment can be controlled more appropriately.

The bathroom environment control device controls the hot water temperature of the bathtub using the information on the interval between the R waves of the heartbeat and the information on the body movement.

For this reason, it is possible to provide a bathtub with a comfortable temperature for a bather to be measured.

The bathroom management system according to claim 3 is the bathroom management system according to claim 1 or 2, further comprising an alarm. Further, the bathroom environment control device controls the alarm using the information on the R wave interval of the heartbeat and the information on the body movement. The “alarm” here includes not only an alarm sound but also an alarm lamp.
Here, the bathroom environment control device controls the alarm using the information on the interval between the R waves of the heartbeat and the information on the body movement. For example, when the interval between the R waves of the heartbeat becomes very short and there is no body movement for a predetermined time, it can be determined that the measurement target is in an abnormal state. For this reason, if a predetermined threshold is provided for the interval between R-waves of heartbeats and body movement, an alarm device can be activated in such an abnormality. Therefore, it is possible to convey the abnormal state of the measurement target to the person or a third party. For example, when the interval between the R waves of the heartbeat becomes very long and there is no body movement for a predetermined time, it can be determined that the measurement target may be asleep. For this reason, if a predetermined threshold value is provided for the interval between the R wave of the heartbeat and the body movement, the alarm device can be activated when there is a possibility that the measurement target is asleep. Therefore, it is possible to prevent the measurement object from falling asleep.

Moreover, the bathroom environment control device causes the hot water heater to supply hot water of a predetermined temperature to the bathtub using the information on the interval between the R waves of the heartbeat and the information on the body movement.
Here, the bathroom environment control device causes the hot water heater to supply hot water of a predetermined temperature to the bathtub using the information on the interval between the R waves of the heartbeat and the information on the body movement.

For this reason, if a predetermined threshold is set for the interval between R-waves and body movements of the heartbeat, a little hot water is added to the bathtub to stimulate the measurement object when the measurement object may be asleep.

The bathroom management system 100 mainly includes a bathroom controller 40 and a hot water heater / water heater 30.
[Components of bathroom management system]
(1) Bathroom controller As shown in FIG. 3, the bathroom controller 40 mainly includes a microwave transmission / reception unit 41, a microwave sensor 42, an R wave interval calculation unit 43, a hot water temperature control unit 44, and an alarm unit 45. Composed.

The microwave transmission / reception unit 41 transmits and receives microwaves. In addition, this microwave transmission / reception part 41 is arrange | positioned so that a microwave may be irradiated to the chest of the bather 10 in the state where the bather 10 sat down in the bathtub 20.
The microwave sensor 42 measures the heartbeat and body movement of the bather 10 based on the signal from the microwave transmission / reception unit 41. Note that the Doppler effect of microwaves is used for measuring heartbeats and body movements. The R wave interval calculation unit calculates the R wave interval based on heartbeat information from the microwave sensor 42. The interval between the R wave and the R wave seen in the electrocardiogram waveform (hereinafter referred to as the R wave interval) is not constant but constantly fluctuates. Since the heartbeat is antagonized by the autonomic sympathetic nerve and the parasympathetic nerve, it is possible to clarify the activity status of the sympathetic nerve and the parasympathetic nerve by analyzing the fluctuation of the R wave interval of the heartbeat. Yes (see FIG. 2, where CV-RR is the heart rate variability coefficient). The sympathetic nerve has a function to activate the body to resist physical and mental loads. On the other hand, the parasympathetic nerve has a function of requesting rest / rest. Specifically, if sympathetic nerves are increased due to physical and mental loads, the heart rate increases and the R wave interval is shortened. For this reason, if the R wave interval is shortened, it can be estimated that the tension is in a relaxed state if the R wave interval is shortened. Note that the fluctuation of the R wave interval of the heartbeat is often performed by frequency analysis. When the R wave interval is frequency-analyzed, two components each having a peak appear in a low frequency region of 0.04 to 0.15 Hz (hereinafter referred to as LF) and a high frequency region of 0.15 Hz or higher (hereinafter referred to as HF). . The sympathetic nervous system has a characteristic of not transmitting heart rate fluctuations of 0.15 Hz or higher. Therefore, the ratio of LF to HF (hereinafter referred to as LF / HF) is obtained, and when the LF / HF value is high, it can be estimated that the sympathetic nerve is mainly active, and the LF / HF value is low. Sometimes it can be assumed that parasympathetic nerves are mainly active. The hot water temperature control unit 44 has a comfortable hot water temperature control function, which will be described later, and adjusts the hot water temperature of the bathtub 20 by the function. The alarm unit has an alarm function and a dozing prevention function, which will be described later, and sounds an alarm by these functions.

The hot water supply part 32 adjusts the temperature of the hot water supplied to the bathtub. The hot water faucet 31 supplies hot water whose temperature is adjusted by the hot water supply unit 32 to the bathtub 20. The water heater 33 boils the hot water in the bathtub 20. The temperature sensor 34 measures the temperature of hot water in the bathtub. The chiller 35 cools the hot water in the bathtub 20.

Note that the microwave sensor 42 always measures heartbeats at 1-minute intervals until a comfortable hot water temperature control mode described later is entered. As a result of the determination in step S11, when a heartbeat exceeding the threshold is not detected, the process returns to step S11. As a result of the determination in step S11, when a heartbeat exceeding the threshold is detected, the process proceeds to step S12. In step S <b> 12, the microwave sensor 42 activates the hot water temperature control unit 44. In step S13, the hot water temperature control unit 44 enters the automatic mode and controls the hot water heater / water heater 30 so as to maintain the set hot water temperature. In step S14, the hot water temperature control unit 44 determines whether 5 minutes have elapsed since the start. As a result of the determination in step S14, when 5 minutes have not elapsed since the activation, the process returns to step S14. As a result of the determination in step S14, when 5 minutes have elapsed since the start-up, the process proceeds to step S15. In step S15, the hot water temperature control unit 44 switches to the comfortable hot water temperature control mode.

In step S22, the R wave interval calculation unit 43 calculates the R wave interval from heartbeat measurement information. In step S23, the hot water temperature control unit 44 determines whether the R wave interval is equal to or greater than the hot water temperature change threshold. As a result of the determination in step S23, if the R wave interval is equal to or greater than the hot water temperature change threshold, the process proceeds to step S24. As a result of the determination in step S23, when the R wave interval is less than the hot water temperature change threshold, the process proceeds to step S25. In step S24, the hot water temperature control unit 44 performs hot water temperature maintenance control. In step S25, the hot water temperature control unit 44 determines whether the body movement is equal to or greater than the first threshold value. If the result of determination in step S25 is that the body movement is greater than or equal to the first threshold, the process moves to step S24. If the result of determination in step S25 is that the body movement is less than the first threshold value, the routine proceeds to an irregular measurement routine.

  In FIG. 6, in step S31, the hot water temperature control unit 44 determines whether the state value is “rising” or “falling”. This state value is binary information of “up” and “down”. The initial value of this state value is “down”. In step S <b> 32, the hot water temperature control unit 44 performs hot water temperature rise control on the hot water heater 33 (for example, the hot water heater 33 raises the hot water temperature by 1 ° C.). In step S33, the hot water temperature control unit 44 determines whether the measured hot water temperature measured by the temperature sensor 34 has reached the control temperature. As a result of the determination in step S33, when the measured temperature reaches the control temperature, the process proceeds to step S34. If the result of determination in step S33 is that the measured temperature has not reached the control temperature, processing returns to step S32. In step S <b> 34, the hot water temperature control unit 44 stops the hot water temperature rise control for the hot water boiling unit 33. In step S35, the hot water temperature control unit 44 performs a hot water temperature lowering control on the hot water boiling unit 33 (for example, the chiller 35 lowers the hot water temperature by 1 ° C.). In step S36, the hot water temperature control unit 44 determines whether the measured hot water temperature measured by the temperature sensor 34 has reached the control temperature. As a result of the determination in step S36, if the measured temperature has reached the control temperature, the process proceeds to step S37. If the result of determination in step S36 is that the measured temperature has not reached the control temperature, processing returns to step S35. In step S <b> 37, the hot water temperature control unit 44 stops the hot water temperature lowering control for the hot water boiling unit 33. In step S38, the microwave sensor 42 irradiates the microwave transmission / reception unit 41 with microwaves, and measures the heartbeat and body movement of the bather 10. In step S39, the R wave interval calculator 43 calculates the R wave interval from the heartbeat measurement information. In step S40, the hot water temperature control unit 44 determines whether the irregular R wave interval (R wave interval calculated in step S39) is larger than the regular R wave interval (R wave interval calculated in step S22). If the result of determination in step S40 is that the irregular R wave interval is larger than the regular R wave interval, the process is terminated. If the result of determination in step S40 is that the irregular R wave interval is equal to or less than the regular R wave interval, the process moves to step S41. In step S41, the hot water temperature control unit 44 determines whether the body movement is greater than or equal to the first threshold value. If the result of determination in step S41 is that the body movement is greater than or equal to the first threshold, the process moves to step S42. If the result of determination in step S41 is that the body movement is less than the first threshold, the process moves to step S43. In step S42, the hot water temperature control unit 44 maintains the state value. In step S43, the hot water temperature control unit 44 changes the state value to “decrease” if the state value is “rise”, and to “rise” if the state value is “decrease”. In addition, the raising or lowering range of the hot water temperature immediately after the state value is changed is a normal double.

(3) Alarm function A flowchart showing the alarm function is shown in FIG. Note that the processing shown in this flowchart is periodically performed, for example, every one minute.
In FIG. 7, in step S51, the alarm unit 45 determines whether the measured hot water temperature measured by the temperature sensor 34 has deviated from the appropriate hot water temperature range. As a result of the determination in step S51, when the measured hot water temperature deviates from the appropriate hot water temperature range, the process proceeds to step S52. As a result of the determination in step S51, if the measured hot water temperature does not deviate from the appropriate hot water temperature range, the process is terminated. In step S52, the warning unit 45 determines whether the body movement is smaller than the second threshold value. As a result of the determination in step S52, if the body movement is smaller than the second threshold value, the process proceeds to step S53. If the result of determination in step S52 is that the body movement is greater than or equal to the second threshold value, the process ends. In step S53, the alarm unit 45 sounds an alarm.

(4) Dozing prevention function The flowchart showing the dozing prevention function is shown in FIG. This dozing prevention function is executed in synchronization with the comfortable hot water temperature control function.
In FIG. 8, in step S <b> 61, the microwave sensor 42 irradiates the microwave transmission / reception unit 41 with microwaves, and measures the heartbeat and body movement of the bather 10. In step S62, the R wave interval calculation unit 43 calculates the R wave interval from the heartbeat measurement information. In step S63, the warning unit 45 determines whether the R wave interval is equal to or greater than the first doze threshold. If the result of determination in step S63 is that the R wave interval is greater than or equal to the first doze threshold, the process moves to step S64. As a result of the determination in step S63, if the R wave interval is less than the first doze threshold, the process ends. In step S64, the warning unit 45 determines whether the body movement is equal to or less than the second dozing threshold. If the result of determination in step S64 is that the body movement is less than or equal to the second dozing threshold, the process moves to step S65. If the result of determination in step S64 is that the body movement is greater than the second dozing threshold, the process ends. In step S65, the alarm unit 45 determines whether 5 minutes have elapsed since the process of step S61. As a result of the determination in step S65, when 5 minutes have elapsed since the process in step S61, the process proceeds to step S66. As a result of the determination in step S65, if five minutes have not elapsed since the process in step S61, the process ends. In step S66, the alarm unit 45 sounds an alarm.

  In step S61, the microwave sensor 42 measures heartbeat and body movement, and this measurement is also performed in combination with the measurement in step S21 of the flowchart shown in the comfortable hot water temperature control function. In step S62, the R wave interval calculation unit 43 calculates the R wave interval from the heartbeat measurement information.

[Characteristics of bathroom management system]
(1)
In bathroom management system 100 according to the present embodiment, microwave sensor 42 measures a heart rate. Then, the R wave interval calculation unit 43 obtains the R wave interval. Furthermore, the hot water temperature control unit 44 controls the hot water temperature of the bathtub 20 so that the R wave interval is equal to or greater than a predetermined threshold. Therefore, the bather 10 can obtain a comfortable bathing environment.

(2)
In bathroom management system 100 according to the present embodiment, microwave sensor 42 measures body movement. And the hot water temperature control part 44 performs hot water temperature maintenance control, without performing comfortable hot water temperature control, when the body motion exceeding a threshold value is detected. That is, the hot water temperature control unit 44 determines whether the heartbeat is fluctuating due to physical and mental loads or fluctuating due to body movement. Therefore, the possibility that the bathing environment of the bather 10 is led from a comfortable one to an uncomfortable one can be eliminated. As a result, the bathing environment can be controlled more appropriately.

In the bathroom management system 100 according to the present embodiment, the hot water temperature control unit 44 switches from the automatic mode to the comfortable hot water temperature control mode 5 minutes after the hot water temperature control unit 44 is activated. For this reason, when the heartbeat of the bather 10 has settled down to a certain level, the comfortable hot water temperature control mode is entered. Therefore, the heart rate can be measured with a certain degree of accuracy even in the initial stage of the comfortable hot water temperature control mode (5).
In the bathroom management system 100 according to the present embodiment, the R wave interval calculation unit 43 is activated in conjunction with the hot water temperature control unit 44 switching from the automatic mode to the comfortable hot water temperature control mode, and is synchronized with the heartbeat measurement. Start calculating the R wave interval. For this reason, the R wave interval calculation unit 43 can be activated at an appropriate timing. Therefore, it can contribute to energy saving.

(6)
In the bathroom management system 100 according to the present embodiment, the alarm unit 45 sounds when the R wave interval is equal to or greater than the first doze threshold, the body movement is equal to or less than the second doze threshold, and a predetermined time has elapsed. For this reason, the bather 10 can be prevented from falling asleep.
(7)
In the bathroom management system 100 according to the present embodiment, when the measured hot water temperature measured by the temperature sensor 34 exceeds the hot water temperature threshold, the alarm unit 45 sounds an alarm. Therefore, it is possible to prevent the hot water temperature from becoming too high or too low. Note that when the body movement is equal to or greater than the second threshold, the alarm unit 45 does not sound an alarm. That is, if it cannot be determined that the bather 10 feels stress with respect to the hot water temperature, the alarm is not sounded. For this reason, it is possible to prevent an extra alarm from sounding. Therefore, it is possible to prevent the bather 10 from being given extra stress.

(8)
In bathroom management system 100 according to the present embodiment, microwave sensor 42 is employed for heart rate measurement and body movement measurement. For this reason, it is possible to measure heartbeat and body motion almost simultaneously with one sensor. Therefore, the bathroom management system 100 can have a simpler configuration. The microwave sensor 42 measures the heartbeat and body movement without contacting the bather 10. For this reason, the freedom of the bather 10 is ensured. Therefore, the heart rate and the subject can be measured without applying stress to the bather 10.
