FIG. 2 shows a specific configuration of a human body sensor 5 including a human body detection sensor 51 using an artificial retinal chip and an infrared sensor 52. Human body detection sensor 51
Is composed of an imaging device 6 that detects a human body and processes the detected image, and a control device 7 that supplies a control signal to the imaging device 6 and determines processing information. And
In addition to the human body detection sensor 51, an infrared sensor 52 is provided in the same case body, the control device 7 is shared, and the monitoring when the bathroom 1 is dark is mutually supplemented.

The image pickup section 8 of the image pickup apparatus 6 comprises an image detection section 9 consisting of 32 × 32 pixels (= 1024 pixels), an imaging lens 10, a scanner 11, a multiplexer 12, and a scanner drive control section 13. ing. The image detecting section 9 may use a part of 128 pixels vertically and 128 pixels horizontally. The pixels of the image detection unit 9 are monochrome 256 gradation “level 0 (black) to 255 (white) 256
It is expressed by "gradation."

In the image pickup section 8, an image in the bathroom is formed on the image detecting section 9 by the image forming lens 10. The drive of the scanner 11 is controlled by a scanner drive control unit 13, and controls each pixel row of the image detection unit 9 so as to sequentially enter a light receiving state (on state) at regular intervals. Photocurrents simultaneously output from the pixels in one column in the light receiving state are converted from analog data into serial data by the multiplexer 12, amplified by the amplifier 14, and then input to the image processing unit 15. The conversion from analog data to serial data may be performed by a control unit provided externally or by an IC provided separately.

Each pixel of the image detecting section 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.
The reset terminal 22 is connected to the scanner 11, and the photocurrent output terminal 23 is connected to the multiplexer 12.

In FIG. 2, the gain adjustment unit 16 checks the image average value (brightness of the image) in the image processing unit 15 and, if the image average value is out of an appropriate range, the amplifier 14 controls the imaging device 6. The gain is adjusted, and the accumulation time of the image detection unit 9 is adjusted by the scanner drive control unit 13 so that the light is adjusted so that an image with appropriate brightness is obtained.

In the imaging device 6 using the artificial retina, the average value of the image is expressed by the gradation (0 gradation (black) to 255 gradation (white)) of all 32 × 32 pixels constituting the image detecting unit 9. 25
(6 gradations) and is represented by a value from 0 to 255. The average value of the image 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, the gain is fixed to an appropriate gain,
The accumulation time may be adjusted. Alternatively, the gain may be adjusted by fixing an appropriate accumulation time.

In FIG. 2, at least an image detecting section 9 for performing image pickup and an image processing section 15 for performing image processing.
Is composed of one chip. This chip is called an artificial retinal chip. Also, on the back side of this chip,
The control device 7 is provided. The control device 7 is composed of a microcomputer, and incorporates therein, as software, an area dividing means 24 for dividing a detection area for performing a detection process by the human body detection sensor 51 into a plurality of areas. is there.

More specifically, as shown in FIG. 4, a point table 25 for processing image information input to the image processing section 15 is divided into a plurality of areas. That is, the imaging capability range detectable by the human body detection sensor 51 (corresponding to the entire point table 25) is 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. As a result, a part of the detection processing area that can be detected is used as a sensor detection area for actually detecting and processing, thereby limiting the processing range of the image and increasing the speed of the image processing.

Further, the detection area 26 is set to the washing area 3
It is divided into two areas of 0 and bathtub area 31. Further, the detection area 26 may be divided into three areas: a washing area 30, a bathtub area 31, and an entrance area.

The imaging lens 10, the imaging device 6, and the control device 7 constituting the human body detection sensor 51 are housed in one case together with the infrared sensor 52, and the wall, ceiling, etc. of the bathroom 1 are set as a human body sensor set. Attached to. The human body detection sensor 51 and the infrared sensor 52 may be built in the bathroom dryer 91 described above, or may be provided integrally.

Then, the detection output of the imaging device 6 and the detection output of the infrared sensor 52 are input to the judgment means 32, respectively. The determining means 32 comprehensively determines the presence or absence of a bather, the movement of the bather, and the like in the bathroom based on the output from the imaging device 6 and the output from the infrared sensor.

The image detected by the artificial retina is processed as follows. The image processing unit 15 receives image information from all pixels constituting the image detection unit 9 at regular intervals. The image processing unit 15 receives the image information at regular time intervals,
The image information is processed and output to the judging means 32 to monitor the movement of the bather.

More specifically, first, the image processing unit 15 calculates the difference (difference) in the amount of received light between the image (previous image) a predetermined time earlier detected by the image detection unit 9 and the current image (current image). I do. Pixels having a positive difference are represented by +, negative pixels are represented by-, and pixels having a difference of 0 are represented by 0.

Since the movement of the object can be determined by the boundaries of the image, the movement of the boundaries of the image appears as a positive or negative difference there. Thereby, the moving direction of the image boundary is estimated. By looking at the sum of the differences, it is possible to roughly grasp the movement of the person. Further, the above-described analysis method is applied to a two-dimensional image. Specifically, the directions on the pixels are divided into four directions of a vertical direction, a horizontal direction, a diagonally upward diagonal direction, and a diagonally downward diagonal direction. Each time, the difference (scalar) between the current image and the previous image is obtained, the motion in each direction is determined from the image of the difference, and the difference in each direction may be represented as a vector. Then, by averaging the difference vector between the pixel and its surrounding 3 × 3 pixels (optical flow), it is possible to detect the presence or movement of a person in the bathroom.

As shown in FIG. 4, the detection area 26 of the human body detection sensor 51 is divided into two areas, a wash area 30 and a bathtub area 31, and the sum of the differences or the amount of movement is detected for each area. . Here, the amount of motion refers to each region 30, 3
This is the average of the scalar amounts of the optical flows of each pixel (scalar average) or the sum of the scalar amounts (scalar sum).

Next, the electrical control relationship between the human body detection sensor and the bathroom dryer will be described with reference to FIG. In the figure, a drive control means 80 for driving and controlling a bathroom dryer 91 is constituted by a microcomputer such as an EEPROM,
Inside, programs composed of various software are incorporated. The drive control means 80 includes a drier operating switch 8 for controlling the operation of the bathroom drier 91.
1. A fan 82 such as a sirocco fan for blowing hot air from the bathroom dryer 91 to the bathroom, the human body detection sensor 51 and the infrared sensor 52 described above are connected.

The switch 81 may be provided on the main body of the bathroom dryer 91, or may be provided on a remote controller at a remote position. Further, the switch 81 may be a timed energized timer switch using a timer.

Further, the drive control means 80 is provided with an operation control means 83 for controlling the operation of the bathroom dryer 91 in at least two stages, high and low. Since there are at least two stages, there may be three stages of strong, medium, and weak, or four to five stages. The operation is controlled mainly by increasing or decreasing the rotation speed of the fan 82 for blowing hot air. As a result, the amount of warm air is varied. A heating amount of a heater or the like may be varied according to the number of rotations of the fan. In particular, in the present invention, it is sufficient to set the air flow to such an extent that the swing of the laundry 92 does not occur due to the warm air from the fan 82 to the weak operation.

The operation control means 83 includes a weak operation means 84 for weakly operating the fan 82, a normal operation means 85 for operating the fan in a normal operation other than the weak operation, and a human body detection sensor operating during the weak operation. 51 comprises weak driving continuation means 86 which operates when a person is detected. Normal operation is generally performed by a strong operation of a fan in order to improve drying efficiency.

In addition, the drive control means 80 is programmed with a human body detection sensor operating means 87 for operating the human body detection sensor 51. Here, the operation refers to supplying power to the control device of the sensor and placing it in a state where human detection is possible. This is equivalent to the standby state of the sensor. The human body detection sensor operating means 87 operates simultaneously with the operation of the weak driving means 84.

Further, the drive control means 80 is programmed with a human body detection sensor stopping means 88 for stopping the operation of the human body detection sensor 51 in the operating state and placing the sensor in a state where no human body is detected. The human body detection sensor stopping means 88 operates simultaneously with the operation of the normal operation means 85 of the bathroom dryer. Further, the drive control means 80 is provided with an infrared sensor operating means 89 for operating the infrared sensor 52, and the infrared sensor operating means 89 operates by supplying power.

Next, a method of monitoring a human body during use of the bathroom dryer 91 will be described with reference to FIG.

In the flow of FIG. 5, the switch 81 of the bathroom dryer 91 is turned on to dry the bathroom, heat the laundry, and dry the laundry (step S1). This switch 8
In response to the ON signal of 1, the weak operation means 84 provided in the operation control means 83 of the bathroom dryer operates to start the weak operation of the fan 82 (step S2). When the power is supplied to the drive control unit 80 of the bathroom dryer, the infrared sensor 52 is activated (step S3), and the human body detection sensor 51 is activated by the operation of the weak operation unit 84 (step S4). It will be.

As described above, at the time of starting the operation of the bathroom dryer, the operation control means 83 controls the fan 82 with a weak operation that does not cause the laundry to sway. It is preventing. That is, the laundry is not erroneously detected as a human body. At the same time, at the start of operation, by operating the human body detection sensor 51, the sensor is set to a standby state,
A human body can be detected so as not to hinder human body monitoring at a later time.

It is sufficient that the initial weak operation time at the start of operation is set to about several minutes by the program of the weak operation means 84. When the bather starts to enter the bathroom during standby by the operation of this sensor, the infrared sensor 52 detects a person and turns on (step S5), and the human body detection sensor 51 detects the amount of movement to detect the human body. (Step S6). Due to the human detection by the human body detection sensor 51, the weak operation of the dryer is continued as it is via the weak operation continuation means 86 (step S7). Then, a flow of human body monitoring is entered (step S8).

Here, the human body monitoring flow is a function flow that detects the stoppage of the bather's operation and, when the stoppage time elapses a predetermined time, notifies another person in a remote place that the abnormality is abnormal.

Next, the flow of this human body monitoring will be described. During the monitoring of the human body, the operating state and the stationary state of the human body are detected by imaging the human body at regular intervals by the imaging device 6 and comparing the previous image with the current image as described above. .

When it is detected that the movement of the human body has stopped, if the stop state continues for a certain period of time (in the case of Yes in step S9), it is assumed that the human body has fallen in the bathroom, and it is determined that the state is abnormal. A signal is output from the means 32 and is notified by a notification means such as a buzzer located at a remote place (step S10).

The release of the notification after the notification may be performed, for example, by an ON signal of a bathroom intercom switch provided on the kitchen remote controller.

In the flow of monitoring the human body, if the human body detection sensor 51 does not detect the stoppage of the operation of the bather (NO in step S9), the infrared sensor 52
Is turned off (in the case of YES in step S11), and when the human body detection sensor 51 does not detect the amount of movement (in the case of YES in step S12),
It is determined that the person has left the bathroom (step S1
3). Since the bath temperature may be erroneously determined as the human body temperature by using only the infrared sensor 52, the weak point of the infrared sensor 52 is complemented by using the human body detection sensor 51.

Next, returning to step S4, if the infrared sensor 52 or the human body detection sensor 51 does not detect a person even after several minutes while the infrared sensor 52 and the human body detection sensor 51 are operating (step S4). S
5, if no at step S6), the operation control means 8
The operation of the bathroom drier is switched from the weak operation to the normal operation via Step 3 (Step S14). The normal operation is a general operation state that is used daily when a bathroom dryer is used, and usually means a strong operation. Since there is no person in the bathroom, the clothes are dried quickly.

In addition, during normal operation, the operation of the human body detection sensor 51 is stopped by the human body detection sensor stopping means 88 (step S15). When the operation of the human body detection sensor 51 is stopped, even if the laundry is shaken by the hot air, no detection is made. As a result, it is possible to prevent erroneous detection of human body detection by detecting the amount of movement of the laundry.

On the other hand, since the infrared sensor 52 is operated during the normal operation (step S16), if a person jumps into the bathroom rapidly while the bathroom is being heated, the person can be detected. Has become. As a result, it is possible to shift to the detection of the motion amount by the human body detection sensor 51 described later.

When a person is detected by the infrared sensor 52 during normal operation (Yes in step S17)
In step S18, the detection signal is input to the operation control unit 83, and the operation of the bathroom dryer is set to be weak by the operation control unit 83 (step S18). At the same time, the human body detection sensor 51 is operated by the human body detection sensor operating means 87 (step S19).

As a result, human body monitoring can be performed while preventing erroneous detection due to hot air from the dryer. That is, during the operation of the bathroom dryer (No in step S20), the infrared sensor 52 and the human body detection sensor 5
If both of them detect a person (YES in steps S5 and S6), the flow shifts to the above-described human body monitoring flow while continuing the weak driving (step S8).

However, the turning off of the switch 81 of the bathroom dryer or the end of the dryer operation by the timer switch (in the case of YES in step S20), the fan 82
Stops (step S21). Thereafter, the flow shifts to the flow of human body monitoring.

The above-described embodiment shows a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope.
For example, in the present embodiment, the system bathroom has been described. However, the present invention is not limited to this example and can be installed in other existing bathrooms. Although the bathroom dryer and the human body detection sensor are connected by a wired connection cord, they may be linked by a wireless transceiver. Also,
The human body detection sensor used a sensor with a low number of pixels.
The same effect can be expected by using an image sensor according to the present invention.

[0051]

According to the present invention, it is possible not only to enable monitoring of the human body even during the drying operation by the bathroom dryer, but also to avoid erroneous detection of the human body detection sensor due to the swing of the laundry due to the warm air. it can. In addition, when the human body is detected, by continuing the weak driving, a comfortable feeling of use can be obtained continuously without causing a change in the amount of warm air, and the influence of the swing of the laundry can be prevented beforehand. When is not detected, the operation is performed in a normal operation (strong operation) other than the weak operation, so that the drying efficiency of the dryer is not reduced.
Further, when the human body is not detected, by activating the human body detection sensor and stopping the operation of the human body detection sensor, it is possible to eliminate the erroneous detection of the human body due to the swing of the laundry while using the dryer at full capacity. In addition, during normal operation, by stopping the operation of the human body detection sensor and activating the infrared sensor, erroneous detection due to the swing of the laundry by the human body detection sensor is prevented, and the infrared sensor is activated, so that the bathroom sensor is heated. It is possible to detect a person even when a bather suddenly enters, and to shift to a human body monitoring mode.
