[0013]
The imaging unit 8 of the imaging device 6 includes an image detection unit 9 having a resolution of 128 × 128 pixels, an imaging lens 10, a scanner 11, a multiplexer 12, and a scanner drive control unit 13. The image detection unit 9 may use 32 × 32 pixels, and may perform image detection processing using some of the many pixels. Each pixel of the image detection unit 9 is expressed by 256 monochrome gradations “256 gradations of level 0 (black) to 255 (white)”.
[0014]
In the imaging unit 8, the image in the bathroom is imaged on the image detection unit 9 by the imaging lens 10. The scanner 11 is driven and controlled by a scanner drive control unit 13, and the scanner drive control unit 13 controls each pixel column of the image detection unit 9 so as to sequentially enter a light receiving state (on state) at regular intervals. .
The photocurrents simultaneously output from the pixels in one column in the light receiving state are combined into a plurality of electrical signals by the multiplexer 12, amplified by the amplifier 14, and then output as analog voltages. Conversion from analog data to digital data is performed by a converter of the control device 7.
[0015]
Each pixel of the image detection unit 9 is constituted by a pixel core circuit 17 as shown in FIG. The pixel core circuit 17 includes a light receiving element 18, a charge storage circuit 19, and a sensitivity variable circuit 20. A sensitivity variable terminal 21 and a reset terminal 22 are connected to the scanner 11, and a photocurrent output terminal 23 is connected to the multiplexer 12. ing.
[0016]
In FIG. 2, the gain adjustment unit 16 checks the image average value (image brightness) in the image output unit 15, and adjusts the gain of the imaging device 6 by the amplifier 14 if the image average value is out of an appropriate range. At the same time, the scanner drive control unit 13 adjusts the accumulation time of the image detection unit 9 to adjust the light so that an image with appropriate brightness can be obtained. This dimming may be performed for each of the divided detection areas described later.
[0017]
In the imaging device 6 using the artificial retina, the average image value is an average value of gradations (256 gradations from 0 gradation (black) to 255 gradations (white)) in all pixels constituting the image detection unit 9. Yes, represented by a value between 0 and 255.
This average image value is determined by the gain of the amplifier 14 and the accumulation time of the image detector 9.
Here, the gain corresponds to the aperture of the camera, and the accumulation time corresponds to the shutter speed of the camera. Therefore, in order to obtain an appropriate image average value of the imaging device 6, it is only necessary to fix the gain to an appropriate value and adjust the accumulation time. Alternatively, an appropriate accumulation time may be fixed and the gain adjusted.
[0018]
In FIG. 2, at least the image detection unit 9 that performs imaging, the scanner 11, the scanner drive unit 13, and the gain adjustment unit 16 are configured by one chip. This chip is called an artificial retina chip.
Further, a control device 7 is provided at the position of the back surface of the chip, and the control device 7 is composed of a microcomputer incorporating various kinds of software, and a detection area in which detection processing by the human body detection sensor 51 is performed. The area dividing means 24 for dividing the area into a plurality of areas is incorporated as software.
[0019]
Specifically, as shown in FIG. 4, the point table 25 for processing the image information input to the control device 7 is divided into a plurality of areas.
That is, the imaging capability range that can be detected by the human body detection sensor 51 (corresponding to the entire point table 25) is first divided into a detection area 26 that requires image processing and a non-detection area 27 that does not perform image processing.
That is, the entire imaging capability range is not set as the detection area.
Thus, a part of the detection processing area where detection processing can be performed is used as a sensor detection area for actually detecting and processing, thereby limiting the image processing range and speeding up the image processing.
Further, the detection area 26 is divided into three areas, that is, an entrance area 29, a wash area 30 and a bathtub area 31, as shown in FIG. 4. The division of the detection area 26 is not limited to this example, and the detection area 26 may be divided into an entrance area 29 and an area other than the entrance area 29. For example, the wash area 30 and the bathtub area 31 may be combined and set as one area. Here, the entrance area 29 refers to an area located in the vicinity of the entrance door to the bathroom in the bathroom. The wash area 30 mainly refers to the area of the floor where the head and body are washed, and the bathtub area 31 refers to the area where the bathtub is located. Image information is sequentially input to the control device 7 for each area divided in this way, and processing such as detection and calculation is performed for each pixel in each area.
[0020]
The imaging lens 10, the imaging device 6, and the control device 7 constituting the human body sensor 51 are housed in one case together with the infrared sensor 52 and attached to a wall surface or the like as a human body sensor set. The mounting position may be such that the entire bathroom 1 including the entrance 4 to the bathroom is within the viewing angle.
[0021]
Then, the detection output of the imaging device 6 and the detection output of the infrared sensor 52 are respectively input to the determination unit 32. Based on the output from the imaging device 6 and the output from the infrared sensor 52, the determination means 32 comprehensively determines the presence / absence of a bather in the bathroom and the movement of the bather.
[0022]
The image detected by the artificial retina chip is subjected to image processing as follows.
The control device 7 that controls and processes the image receives image information from all the pixels constituting the image detection unit 9 at regular intervals, and receives the image information at regular intervals, processes the image information, and determines means. 32, the movement of the bather is determined.
[0023]
Next, an image processing method for extracting a person's movement from an image captured by the imaging apparatus will be described.
When receiving image information every predetermined time, the control device 7 constituted by a microcomputer analyzes the bather's movement from the image information according to a predetermined analysis algorithm, and monitors the bather's movement.
[0024]
Specifically, it is assumed that an image (bright image) P of a square object has moved from position P1 to position P2 as shown in FIG. At this time, if a bright pixel is represented by symbol B and a dark pixel is represented by symbol D, the previous image is represented by FIG. 10B and the current image is represented by FIG. The images before and after this are temporarily stored by the image storage means 115 in FIG. The captured images are sequentially updated so that both the latest images are always stored. Then, the two images are compared for each divided region by the motion amount calculation means 111, and the received light amount Pp (x, y) of the previous image p is calculated for each pixel (x, y) of each region. Difference (motion amount) from the received light amount Pn (x, y) of the current image n
D (x, y) = Pn (x, y) -Pp (x, y)
And the calculation result can be obtained as a difference image as shown in FIG. In the difference image of FIG. 11, a pixel having a positive difference D (x, y) is represented by a + symbol, a negative pixel is represented by a − symbol, and a pixel having a zero D (x, y) is represented by a 0 symbol. Yes. By capturing the sum of such differences, it is possible to determine for each region whether or not there is motion, and this determination is performed by the motion presence / absence determination unit 114. If there is no amount of movement, it is determined that there is no movement, and if it has occurred, it is determined that there is movement.
[0025]
On the other hand, the motion presence / absence region detection means 112 detects whether or not each of the divided regions has a motion. That is, the picked-up image picked up by the image pickup device 6 is read into the control device 7 at regular intervals in the order of the entrance area 29, the wash area 30 and the bathtub area 31, and the moving area is analyzed by analyzing this image data. Is to be detected. For this detection, for example, the above-described region where the amount of motion has occurred may be detected as a region having motion. Alternatively, a change in voltage caused by a person's movement may be captured, and the area having the change may be detected as the area having the movement. Then, the specific region appropriateness determining means 113 determines whether or not the region where the motion occurs corresponds to a region specified in advance. The specific area means the bathtub area 31 or the wash area 30, and is an area excluding the entrance area 29. Whether or not the region with movement is a specific region is determined by, for example, whether or not the signal matches, or by sequentially searching other detection regions and determining that there is no movement in a region other than the specific region. Yes. Such a search is performed in the microcomputer by sequentially changing the state based on the presence / absence of motion and the signal of the region having motion.
[0026]
The human body detection sensor 51 includes a sensitivity adjustment circuit (not shown) for automatically adjusting the sensitivity. The sensitivity is increased when the bathroom is dark, and the sensitivity is decreased when the bathroom is bright. By doing so, the detection accuracy is increased.
[0027]
Next, determination of whether or not a person has entered the bathroom 1 will be described. Switch on the remote controller of the hot water device in advance.
In FIG. 5, when a person begins to enter the bathroom 1, first, the infrared sensor 52 in a standby state detects a human body and is turned on (step S1), and a timer is set (step S2). If a person is detected in the washroom (step S3), it is determined that the person has entered the room (step S4).
In this entrance determination, since the human body detection by the human body detection sensor 51 takes time for imaging and calculating the amount of motion, or the monitoring sensitivity is low when the bathroom 1 is dark, the infrared sensor 52 is used together. After the detection by the sensor 52, the human body detection sensor 51 detects the person together, thereby compensating for the weak point of the human body detection sensor 51 and ensuring the entrance into the room.
[0028]
Further, when the infrared sensor 52 is turned off even when leaving the bathroom 1 (in the case of no in step S5), and the human body detection sensor 51 does not detect the amount of movement (in the case of no in step S6). ), It is determined that the user has left the bathroom 1 by turning off the exit switch 80 (step S7).
If only the infrared sensor 52 remains at the entrance, it may be turned off, and it may be erroneously determined that the sensor has left. It is complemented by using other sensors.
[0029]
Even when the human body detection sensor 51 does not detect a person in the washroom 3 (in the case of no in step S3), if the person is detected in the bathtub 2 (step S8), the infrared sensor 52 and the human body detection are detected within a predetermined time. When both the sensors 51 detect people (steps S9 and S10), it is determined that they are entering the room (step S4).
After determining that the room has entered, a timer may be set so that the detection duration of the sensor matches the average bathing time.
[0030]
The human body detection sensor 51 is attached to the ceiling of the bathroom 1 or the upper part of the bathroom wall. This position is an optimal position where a person can see the movement of the person in the bathroom provided with the wash basin 3 and the bathtub 2 in a standard bathroom. It is.

The cable 41 between these communication units uses a power superposition type two-core cable, and it is sufficient to superimpose and transmit the sensor signal and the normal hot water supply control signal.
[0041]
FIG. 9 is an explanatory diagram showing the contents of the data storage unit 54 constituted by an EEPROM or the like provided in the human body detection sensor in order to operate the human body detection sensor and notify the notification means.
[0042]
In FIG. 9, the voice storage unit 101 stores voice data for informing the above-described remote control informing means 61 and 71 of the voice. This voice storage unit 101 is an operation guide voice storage unit 141 that stores voice data for notifying operation procedures of a water heater and the like, and an action of moving the body with a message “Please move” to the bather The operation request notification voice storage unit 107 that stores voice data for notifying the request of the person and when the bather's movement stops and a predetermined time has elapsed, say "please go to the bathroom" An alarm notification voice storage unit 108 that stores voice data for issuing an alarm and an examination guide voice storage unit 142 that stores voice data for reporting the contents of an examination at the time of a driving inspection of the human body detection sensor. It is.
[0043]
An image storage unit 102 stores image display data for displaying an image for human body detection on the display means 64 and 74 provided in the remote controller.
This image storage unit 102 is for displaying functions necessary for human body detection by an image, and for example, an operation image for storing image data for displaying a screen necessary for initial operation of human body detection on a display means. The storage unit 103, the stop image storage unit 104 that stores image data for displaying the state where the movement of the human body is stopped on the display unit, and the image data for displaying the state for which the notification unit is notified on the display unit The notification image storage unit 105 and the other storage unit 106 that stores data necessary for displaying other images are included. In addition, the storage unit 106 stores a plurality of still image data in order to display a moving image. This moving image means not a captured image of the human body but a pseudo image indicating that the human body is moving, for example, an image such as an animation of a moving doll. Privacy is protected by anthropomorphizing not only moving images but also stopped images. The bathroom information storage means 109 is for storing bath and bathroom information necessary for human body detection during the trial operation that is the first operation. For example, by inputting bathroom information such as bathtub size, color, shape, bathroom floor color, wall color, etc., the threshold value of the human body detection sensor is corrected to detect movement in an optimal state. Is for.
[0044]
In this embodiment, the image storage unit 102 is provided on the human body detection sensor 51 side. However, the image storage unit 102 is not limited to this example. As shown in FIG. The computer may be provided integrally or separately. The bath remote controller control unit 65 is programmed with a motion image display unit 133 for calling image data from the other storage unit 106 of the image storage unit 102 and displaying the image data on the display units 64 and 74. The motion image display means 133 is activated by a motion amount detection signal from the motion amount calculation means 111. Then, a plurality of (for example, five) still images are sequentially displayed on the screen of the display means at regular time intervals, whereby a moving image can be formed.
[0045]
The bath remote controller 65 calls the still image data corresponding to the stopped state from the plurality of still images described above from the other storage unit 106 of the image storage unit 102, and displays the display means 64, 74. The stop image display means 134 for displaying on is programmed. The display by the stop image display unit 134 is canceled by the display cancellation unit. For example, the release means is released upon receiving a detection signal obtained by detecting the movement of the human body. Simultaneously with the cancellation, a motion image may be displayed.
[0046]
Further, the stop image display means 134 is activated by a signal for determining whether or not the human body has been stopped by the determination means 32. The bath remote controller 65 is programmed with a switching unit 135 for canceling the display by the stop image display unit 134 and operating the motion image display unit 133 to switch to a moving image. Specifically, the switching means 135 is operated by a signal from the operation switch 129 of the remote controller.
[0047]
When the human body detection operation is performed, the operation switch of the remote controller is operated in advance, and the initial screen image necessary for the operation is called up and displayed on the display means 64 and 74 from the operation image storage unit 103 on the human body detection sensor 51 side. Then, select a specific screen from the screen and start the operation. From the second time, these may be stored and used. Simultaneously with the operation, a part of the voice data is called from the operation guide voice storage unit 141 on the human body detection sensor 51 side, and is notified by voice by the notification means 61 and 71 such as a speaker. For example, the operation guide voice storage unit 141 stores the operation procedure as voice data such as “hot water temperature has been changed” when the hot water temperature setting is changed, and “automatic hot water filling” when automatic hot water is supplied. It is memorized by.
[0048]
Next, when the entrance determination is made as described above, a human body stop detection flow is entered as shown in FIG. 6, and the human body is imaged at predetermined time intervals by the imaging device 6 as described above (step S11). The captured previous image and the current image after a predetermined time are temporarily stored in the control device 7 (step S12).
[0049]
Next, the difference (movement amount) between the light reception amount of the previous image and the light reception amount of the current image is calculated for each pixel in each region by the motion amount calculation means 111 programmed in the control device 7 (step S13). ). By detecting the motion of the human body by the motion amount calculation, the image data is called from the image storage unit 102, and the motion image display means 133 displays a moving image on the display means 64 and 74 (step S21). The moving image may be composed of, for example, an animation of moving the hand and an image of moving the body up and down and left and right. Specifically, it may be constituted by a plurality of still picture drawings or the like having slightly different patterns. On the other hand, the motion presence / absence region detection means 112 detects a region where motion has occurred (step S14).
[0050]
These pieces of information are sent to the determination means 32 of the control device 7. In the determination means 32, the specific area appropriateness determination means 113 determines whether or not the area where the movement occurs corresponds to the area specified in advance, that is, the bathtub area 31 or the wash area 30. Further, the determination means 32 determines whether or not there is a movement by the movement presence / absence determination means 114 in parallel.
[0051]
When the area where the movement occurs corresponds to the bathtub area 31 or the wash area 30 (Yes in Step S15), and when it is determined that there is no movement (Yes in Step S16), It is estimated that the bather has fallen in the bathroom, and it is determined that the movement of the person has stopped (step S17).
Based on the stop determination, the process proceeds to the next notification alarm step.
[0052]
Further, when it is determined that there is movement in the bathtub or wash area (in the case of No in step S16), the imaging, calculation, and determination are updated and repeated at predetermined time intervals as described above. Furthermore, in step S15, when the region where the movement occurs is other than the bathtub or the washing area (in the case of no in step S15) and it is determined that there is no movement thereafter (in the case of yes in step S18). On the assumption that the infrared sensor 52 is turned off (in the case of YES in step S19), the exit switch 80 is turned off to determine that the user has left the bathroom (step S20). In addition, when the region where the movement occurs is other than the bathtub or the washing area (in the case of No in Step 15) and the movement continues thereafter (in the case of No in Step S18), the bathroom entrance Because it is considered to be active in the vicinity, it is continuously monitored. In this way, even when the vehicle stops at the entrance region, it is not determined that the vehicle has stopped, so that an alarm due to an erroneous determination is not generated.
[0053]
Next, the human body monitoring flow shown in FIG. 13 will be described.
When the stop determination is made as described above (step S30), a stop determination signal is output to stop the moving image, and the stop image display means 134 is operated to display an image indicating the stop state. It is displayed on the display means 64 and 74 (step S30). That is, the motion image stops, and the stop image is displayed instead. Thereby, the bather is conscious of starting to move and the family member can grasp the state of the bathroom before the alarm. This stop image is configured by using one still image that constitutes a part of the above-described moving image, and image creation is simplified by sharing the image. Further, by using a dot matrix display for the display unit of the remote controller, even if the image is shared, it becomes difficult for the pattern to shift, and it is easy to check the image from the outside.
[0054]
Then, the timer means 117 provided in the control device 7 of the human body detection sensor 51 starts the stop count operation (step S31). This timer means 117 is started by a stop determination signal from the determination means 32 and counts a predetermined time. The predetermined time is divided into two stages. The predetermined time of the first stage is set to 90 seconds, for example, and the predetermined time of the second stage subsequent thereto is set to 30 seconds. The predetermined time is not limited to this example, and can be arbitrarily set other than this.
[0055]
As for the relationship between the timer means 117 and the display means 64 and 74, the timer means 117 uses the clock function of the microcomputer, which is the control means of the human body detection sensor 51, to count the time in normal times. This time display is displayed on the display means 64 of the bath remote control 60 by the time display means 130 of the microcomputer of the bath remote control section 65 provided in the bath remote control 60. Further, the microcomputer of the bath remote controller 65 is provided with a count display means 131 for displaying the count on the display means 64 after a set time has elapsed from the start of counting by the timer means 117 after the stop determination. Further, the microcomputer of the bath remote controller 65 is provided with a switching display means 132 for switching the screen of the display means 64 from time display to count display.
[0056]
In FIG. 13, when the set time has elapsed after the stop determination (Yes in Step S40), numerical values are displayed on the display means 64 and 74 by the count display means 131 (Step S41). Instead of a numerical value, it may be displayed in a different picture according to the passage of time. Here, although counting has started, only the display of the count is delayed for a set time from the start of counting, which is a stop determination time, so that the bather feels uneasy about being counted immediately after stopping. Can be wiped off. Further, in response to an operation request to be described later, when the movement is started, the timer is canceled, the count display itself can be omitted, and the number of times of switching to the clock display can be reduced.
[0057]
Furthermore, when the state of no movement continues for the first predetermined time (90 seconds) (step S33), an operation request signal is output from the human body detection sensor 51 side (step S34), and the bath remote controller 60 operates the bather. The request is notified (step S35). As for this notification procedure, information stored in advance corresponding to the stopped scene is read from the operation request notification voice storage unit 107 of the voice storage unit 101 on the human body detection sensor 51 side and the stop image storage unit 104 of the image storage unit 102. Then, the data is transmitted via the analog communication unit 55 and the digital communication unit 56, and notified to the remote control unit by voice and displayed as an image.
[0058]
Specifically, this notification may be performed by voice information and a character image such as “There is no movement in the bathroom. Please move”. This is to prevent a false alarm of the human body detection sensor by requesting the bather to move, since the movement may stop if he / she stays in the bathtub. This notification is performed after a while after being immersed in the bathtub and no longer moving, that is, after the stop determination and after a predetermined time has elapsed. Therefore, the operation request is not made immediately after being immersed in the bathtub.
[0059]
If the human body detection sensor 51 detects a person's movement within the predetermined time after the stop determination (No in step S32), it can be assumed that the bather is alive and the timer is released (step S42). ). At the same time, the display of the stop image by the stop image display means 134 is canceled in response to the detection signal obtained by detecting the movement of the human body (step S43). After the cancellation, the motion image display means 133 may display the motion image again. As a result, a family member at a remote location can know that it has started moving after stopping.
[0060]
Then, after the operation request is notified (step S35), if the stationary state where there is still no movement continues for the second predetermined time (30 seconds) (in the case of yes in steps S36 and 37), the abnormal state is determined. The abnormality detection signal is output from the determination means 32, and stored in advance for informing the other person of the abnormal state from the alarm notification voice storage unit 108 of the voice storage unit 101 and the notification image storage unit 105 of the image storage unit 102. The information is transmitted via the communication unit 53, and the alarm means 61, 71 of each remote controller of the hot water device is alerted by voice and displayed on the display means 64, 74 as an image (step S38).
[0061]
Specifically, this alarm (step S38) is alarmed by, for example, voice information and a character image “Please go to see the bathroom”. Thereby, the abnormality information of the human body by the human body detection sensor 51 can be alarmed simultaneously to the kitchen as well as the bathroom.
[0062]
This alarm signal is transmitted as shown in FIG. 8 via a communication unit comprising a communication IC. That is, the sound and image data are called from the sound storage unit 101 and the image storage unit 102 provided in the human body detection sensor 51 according to the above-described signals, and transmitted to the kitchen remote controller 70 via the analog and digital communication units 66 and 76. The notification means 71 such as a speaker provided on the kitchen remote controller 70 and the display means 74 are notified and displayed. Since the image detection and processing are performed for each of the above-described areas 29, 30, and 31, the response speed for notification and display is increased.
[0063]
The intercom is already in a call-ready state, so a bather who does not move but can speak is immediately out of the bathroom as long as he speaks in an abnormal emergency without pressing the call button. It will be convenient to be able to contact your family.
[0064]
If the human body detection sensor 51 detects a person's movement within a predetermined time after the notification of the operation request (No in step S36), it can be assumed that the bather is alive and the timer is released as described above. (Step S44). At the same time, the display of the stop image by the stop image display means 134 is canceled in response to the detection signal obtained by detecting the movement of the human body (step S45). After the cancellation, the motion image may be displayed again on the display means 64 and 74 of the remote controller. Thereby, the state in the bathroom up to the alarm notification can be grasped from a remote place.
[0065]
Then, after the alarm is notified, a family member rushes to the bathroom and rescues. The notification and the stop image display may be canceled by, for example, turning off the operation switch 129 (step S39). After the operation switch is turned off, the movement amount can be displayed by detecting the movement amount again.
[0066]
Next, an operation inspection when the human body sensor is used for the first time after being attached to the bathroom will be described.
The operation inspection is a concept including a test operation test and a regular operation inspection after a certain period of time has elapsed after the test operation. Further, the initial setting of the human body sensor is performed simultaneously with the trial operation, and the sensor does not function unless the initial setting is made. The operation inspection means 140 is incorporated as software in the microcomputer of the control device 7 described above.
[0067]
FIG. 17 is a flow up to the transition to the trial operation. After initial setting, the trial operation mode is entered. In the trial operation, first, the operation switch 129 provided in the bath remote controller 60 of the hot water device 40 is turned on (step S50).
[0068]
Next, the sensor setting is selected by appropriately pressing the setting switch 126 provided on the bath remote controller 60 shown in FIG. 14 (step S51). Each time this setting switch is pressed, the screen setting can be confirmed and the screen can be switched. When the setting is changed, the operation guide voice notification unit 143 guides by voice that “setting has been changed”. When the sensor setting is selected, the display screen of the display means 64 is in a display state as shown in FIG. When the setting switch 126 is turned on (step 52), the screen is switched to the screen shown in FIG. From this screen, the bathtub or bathroom information necessary for sensor detection is selected and necessary items and data are input (step S53). Here, the bathroom information means, for example, a bathroom size, a bathroom door position (door direction), and the like. After selecting the optimum numerical value and the like by pressing the selection switches 127 and 128, the setting switch 126 is turned on to confirm its contents, and transmitted to and stored in the bathroom information storage means 109 described above (step S54).
[0069]
When necessary items are set and stored (Yes in step S55), the two selection switches 127 and 128 are simultaneously turned on (step S56). As a result, the screen becomes the screen shown in FIG. 20 and the test operation mode can be selected. The selection switch 128 is pressed from this screen to select “trial operation”, and the setting switch 126 is turned on to shift to the trial operation mode shown in FIG. 17 (step S57). The test run mode is an area detection confirmation mode that can detect the amount of movement for each area and check the detection state, and confirms whether images are displayed and voice notifications are made normally in response to actual operation. The actual operation confirmation mode is composed of two modes.
[0070]
The flow shown in FIG. 22 is a flowchart showing the above-described area detection confirmation mode. In the detection confirmation, first, sitting near the entrance door of the entrance / exit 4 of the bathroom is repeated several times (step S58). The voice guide for the inspection may be performed by the notification means 61 of the remote controller through the inspection guide voice notification means 144 shown in FIG. 25 by the human body detection by the human body detection sensor 51. At this time, as shown in FIG. 23, if the bar display is displayed at 3 dots or more on the A part of the display means 64 of the bath remote controller 60 (step S59), the movement detection by the human body detection sensor 51 in the entrance area 29 is normal. It can be confirmed that there is. As described above, since the test operation means for confirming whether or not the human body detection sensor operates normally is provided using the movement amount calculation means 111, the amount of received light can be taken as pixel data and converted into digital data so that a bar display or the like can be performed. Therefore, it is easy to check visually and to check whether the detection of the sensor is normal or not. The contents of the test are guided by voice saying “Sit and stand several times,” so that the person can operate reliably and the sensor can detect accurate movement.
[0071]
Next, through the examination guide voice notification means 144, an announcement is made from the examination guide voice storage unit 142 that “shake the body back and forth while sitting in the center of the washroom 3” (step S60). By moving the body according to this announcement, the operation for the inspection can be surely performed, and when the bar display is displayed at 3 dots or more on the part B of the display means 64 (step S61), the amount of movement in the wash area 30 is determined. It can be confirmed that the detection is normal.
[0072]
Next, an announcement is made from the examination guide voice storage unit 142 with a voice saying "Please enter the bathtub", and the body is shaken back and forth while sitting at the center of the bathtub 2 in accordance with this announcement (step S62). At this time, if the bar display is displayed at 3 dots or more in the C part of the display means 64 (step S63), it can be confirmed that the movement amount detection in the bathtub region 31 is normal. These confirmations can be confirmed by visually observing the display means 64 of the bath remote controller 60 in the bathroom.
[0073]
The display of the A part, the B part, and the C part is not limited to the bar display, and other means such as a line graph display, a pie chart display, and a numerical display may be used. In short, what is necessary is just to be able to visually confirm whether or not the sensor normally detects each divided area. Since the area detected by the sensor is divided and the movement is detected for each area, it is possible to verify and verify the operation for each divided area. Display can be performed, and it is possible to correct light adjustment for each region.
When not detected, it is not displayed on the display means 64. Further, even when the exit switch 80 is not connected, no display is made. This is to prevent forgetting to connect the exit switch 80.
[0074]
Next, “Please move around in the washroom” is announced (step S64). By moving according to the announcement, if the bar display of the D part of the display means 64 is moving up and down (step S65), it can be confirmed that the detection of the infrared sensor 52 is normal. Note that the bar display of the D section is displayed even when no motion is detected, and the bar display moves up and down when the motion is detected. Thus, the detection state of the sensor can be confirmed in the bathroom by utilizing the display means of the bath remote controller of the hot water device. If the confirmation of the area detection is completed (step S66), the operation moves to the actual operation confirmation mode.
[0075]
FIG. 24 shows a flow of confirmation of actual operation. First, the operation switch 129 of the bath remote controller 60 is turned on (step S67). At this time, although not shown in the figure, if the sensor is in an operating state, a character screen “start sensor operation” is first displayed on the display means 64 and 74 of the bath and kitchen remote controller. Next, when the user enters the bathroom 1 (step S68), if the detection is normal, the characters “being bathed” are displayed on each remote controller. Further, when operating in a washroom (step S69), a moving image is displayed if it is normal. Next, when the operation is stopped in the bathroom (step S70), if it is normal, the moving image is stopped and a sound is notified. When the stop is continued for a predetermined time (in the case of YES in step S71), if normal, a countdown display is added. When the timer count is finished (step S72), if it is normal, a voice alarm (“Please go to the bathroom”) is given. Next, when it operates in the bathtub (step S73), it returns to the time of operation, the display is resumed, and when the exit switch 80 is pressed, the display disappears and the confirmation is completed (step S75). In this way, by providing not only the area detection confirmation mode but also the actual operation confirmation mode, it is possible not only to confirm whether the detection of the human body detection sensor is normally performed for each area, but also to normal the actual operation. It is possible to confirm whether or not to operate.
After the test run of the sensor is completed, the first bathing may be started.
[0076]
Next, a periodic operation inspection mode for periodically inspecting whether or not the human body detection sensor operates normally will be described. In FIG. 25, the periodic operation means 145 counts the timer and outputs a signal for starting the inspection to the operation inspection means 140 every predetermined period, for example, every six months. Further, the notification means 146 is a means for prompting the examination when the bather cannot be detected after a certain period of time has elapsed. Here, the prompting of the inspection is to display or notify “Please go to the bathroom” on the display means of the kitchen remote controller 70 by text or voice. If the bather cannot be detected even after prompting the examination, the replacement promoting means 147 prompts the replacement of the human body detection sensor 51. Specifically, the display means of the kitchen remote controller 70 is notified or displayed by voice or text as “A human body sensor is abnormal. Please replace”.
[0077]
FIG. 26 is a flowchart showing the periodic operation inspection mode. In FIG. 26, for example, when the periodic operation means 145 including timer means operates after a certain period after the test operation inspection (step S76), the output is input to the operation inspection means 140. In this mode, the human body is detected. The start of detection may be automatic or may be performed through a predetermined operation procedure. When a human body is detected in the bathroom 1 by the human body detection sensor 51 (step S77), the "sitting and standing" are repeated several times by the notifying means 61 of the bath remote controller 60 via the inspection guide voice notifying means 144 for guiding by voice. Please give a voice message "Please do" (step S78). When the bather operates in accordance with this, if the human body detection sensor 51 is normal, the movement due to the operation is detected.
[0078]
The guidance by voice from the inspection guide voice notification means 144 may be made in a predetermined order. After detecting the movement in the vicinity of the entrance, the movement in the third section of the washing place may be guided and guided. As in the trial run, this guide announces "Please shake your body back and forth while sitting at the center of the wash basin 3" (step S78). If the person moves according to this announcement and the human body detection sensor 51 is normal, the movement is detected.
[0079]
Then, an announcement is made with the voice "Please enter the bathtub", and a person moves according to the announcement, and the movement is detected if the human body detection sensor 51 is normal.
Furthermore, “Please move around in the washroom” is announced with a voice, and according to the announcement, a person moves and the movement is detected if the human body detection sensor 51 is normal (step S79). As described above, after the guidance for the bather is guided by the voice guidance from the notifying means of the remote controller via the examination guide voice notifying means 144, the sensor detects the movement and the predetermined series of examinations is completed. Then, “inspection has been completed normally” is displayed and notified on the display means 64 and the notification means 61 of the remote controller (step S80).
[0080]
In step S77, if the bather cannot be detected after a certain period of time has passed, the notification means 146 is activated to prompt the examination (step S81). Specifically, the display means of the kitchen remote controller 70 displays “Bathroom”. "Please go to" is displayed in characters (step S82). Then, if the human body detection sensor 51 detects a person (YES in step S83), the inspection mode described above is entered, and if the human body detection sensor 51 cannot detect a person (NO in step S83), The replacement facilitating means 147 notifies or displays on the kitchen remote controller 70 by voice or text that “There is an abnormality in the human body detection sensor. Replace it” (step S84).
[0081]
In addition, embodiment mentioned above shows suitable embodiment of this invention, This invention is not limited to this, Various design changes are possible within the range.
Moreover, although the system bathroom was demonstrated in this embodiment, it can install in the existing bathroom other than this without being restricted to this example. Furthermore, the human body detection sensor may use a CCD camera. Moreover, although what connected the human body detection sensor and the alerting | reporting means with the wire was shown, what was connected by radio | wireless may be used. Furthermore, although the operation inspection means is provided for both the test operation inspection and the regular operation inspection, it may be provided for any one of the inspections.
[0082]
