<Control unit>
The control unit 100 includes a human body detecting unit 102, a human body position information accumulating unit 103, a living area estimating unit 104 (living area estimating unit), a human body rising detection unit 105, a next moving place estimating unit 106 (moving destination estimating unit). ), Air conditioning control means 107, storage means 120, and the like. The control unit 100 is provided in an electrical component (in the electrical component box), and drives the indoor unit 1 and the outdoor unit 2 based on information from the remote controller 3 and the sensor unit 18.

  The human body detection unit 102 detects the position of the human body based on image information input every predetermined time from the imaging unit 4 that images the room.

The air conditioning control means 107 performs air conditioning control on the estimated destination.

<Details of imaging means and temperature detection means>
The imaging unit 4 and the temperature detection unit 108 are installed such that the optical axis of the lens faces downward by a predetermined angle with respect to the horizontal line, so that the room in which the indoor unit 1 is installed can be appropriately imaged. Yes. The angle at which the imaging unit 4 faces downward is substantially the same as the angle at which the temperature detection unit 108 faces downward. When the detection ranges in the vertical direction of the imaging unit 4 and the temperature detection unit 108 are different, the upper ends of the detection ranges are aligned. Alternatively, the lower ends may be aligned. Alternatively, for example, in the case of a thermopile having 8 pixels vertically, the detection range of the sensor from the second pixel from the bottom and the detection range of the sensor from the second angle of view from the top, You may arrange in the defined range, such as aligning with the detection range of the imaging means 4.

  The angle of view in the horizontal direction of the image pickup means 4 and the temperature detection means 108 is substantially the same angle. Alternatively, one may be larger than the other, and a substantially equivalent angle of view may be obtained by changing the angle of view by turning. The imaging means 4 and the temperature detection means 108 are provided so as to be positioned in the horizontal direction or the vertical direction. In addition, it is desirable that the image pickup unit 4 and the temperature detection unit 108 be provided close to a position where space can be detected, such as the center of the front surface of the indoor unit 1 and the upper part of the front surface. Thereby, the deviation | shift amount of the acquired image of the imaging means 4 and the acquired image of the temperature detection means 108 can be made small. Further, the image pickup means 4 or the temperature detection means 108 may be at the upper end of the front panel 12 so that a wider range of the room can be seen with the same angle of view.

  Next, imaging by the imaging unit 4 and the temperature detection unit 108 will be described. The imaging unit 4 is configured by a CCD image sensor having 640 × 480 pixels, for example, and the temperature detecting unit 108 is configured by a thermopile having 1 × 8 pixels, for example. A lens is provided in front of the CCD image sensor and the thermopile, and a field image is formed on the sensor.

  The detection element of the thermopile is a heat receiving element arranged one-dimensionally. By rotating the thermopile with the arrangement direction of the detection elements as a rotation axis, scanning is performed in a direction perpendicular to the arrangement direction of the detection elements. Thereby, a two-dimensional radiant heat image of 8 pixels can be acquired in the vertical direction. The number of pixels in the scanning direction (horizontal direction) of the acquired image will be described later.

  The CCD image sensor is a two-dimensional image pickup device, but in order to widen the acquired image range of the image pickup means 4, the CCD image sensor is rotated around the vertical direction of the CCD image sensor as a rotation axis, and horizontal scanning is performed. Do. Thereby, a captured image larger than the number of pixels in the horizontal direction of the CCD image sensor can be obtained.

  The CCD image sensor has an angle of view of 60 °, the thermopile has an angle of view of 5 °, and the image pickup means 4 and the temperature detection means 108 have an angle of view of 150 ° in the horizontal direction and acquire images of the same field of view. Assumed to be performed. In order to obtain an acquired image having an angle of view of 150 °, the thermopile acquires a radiant heat image in the range of 75 ° left and right at every rotation angle of 5 °, and the CCD image sensor Image acquisition may be performed by imaging at three rotation angles.

  The image pickup means 4 (CCD image sensor) can acquire an image having the number of pixels of 1600 × 480 at an angle of view of 150 ° in the horizontal direction. The temperature detection means 108 (thermopile) can acquire a thermal image of 30 × 8 pixels at a field angle of 150 ° in the horizontal direction.

  At this time, since there are overlapping areas in the captured image by the imaging unit 4, the image acquisition of the number of pixels is performed by appropriately deleting or averaging. The number of pixels of the acquired image is an example, and it goes without saying that various selections can be made depending on the angle of view to be acquired, the type of CCD image sensor to be used, and the thermopile.

  At first glance, it seems that the resolution of the thermopile is low, but if it is an application for measuring the temperature distribution in the room for air blow control of the air conditioner AC as in the embodiment, the above resolution is sufficient. It can be performed. Of course, it is needless to say that high resolution is desirable.

  Next, a mechanism for rotating the thermopile or the CCD image sensor will be described. A stepping motor is used as a drive source for rotating the thermopile or the CCD image sensor. A rotating shaft that rotates a thermopile or a CCD image sensor and a drive shaft of a stepping motor are connected via a gear. Even a stepping motor with a small number of steps can obtain a desired rotation angle by selecting a gear ratio. A rotating shaft that rotates the thermopile or the CCD image sensor and a driving shaft of the stepping motor can be connected by a four-bar link, and the rotating motion can be converted into a swinging motion.

  When the drive shaft is connected by the aforementioned gear and link, an error may occur in the rotational position accuracy due to gear backlash and link “play”. For this reason, it is desirable that the rotation direction at the time of imaging of the thermopile or the CCD image sensor at the time of imaging is one direction so that an error of the rotation angle due to “play” does not occur. Further, an adjustment amount for absorbing “play” may be obtained in advance, and the adjustment may be performed when the rotation direction is reversed.

  As described above, the thermopile of the temperature detecting means 108 is composed of eight elements in the vertical direction. Radiant heat is detected by the heat receiving element, and the upper and lower sides of the imaging result correspond to the indoor wall and floor, respectively.

  In the present embodiment, in order to detect the movement of a person, it is desirable that the CCD image sensor is mounted not with a rotational drive system but with a fixed system employing a wide-angle lens. In order to adopt a fixed system, the field of view is expanded to a wide angle lens. Distortion correction control at the end using a wide-angle lens. Furthermore, it becomes possible by enlarging the resolution for distortion correction.

  In order to carry out the present embodiment by the rotational drive method, when there is a person in an area other than the living area by time zone, the CCD image sensor (imaging means 4) is fixed so that the person enters the viewing angle, Confirmation of the status of other areas can be realized by limiting it to once every predetermined time (for example, about once every 10 minutes).

<Control unit>
FIG. 4 is an explanatory diagram illustrating a control block of the control unit according to the first embodiment. The human body detection unit 102 detects the human body in the image from the image data that is the output of the imaging unit 4 and outputs human body position information. An area (area) of human body position information will be described with reference to FIG.

  FIG. 5 is an explanatory diagram of the region of the human body position imaged by the imaging unit and determined by the human body detection unit 102, (a) is an explanatory diagram (side view) of the imaging region in the front-rear direction, and (b) is It is explanatory drawing (plan view) of the imaging area of the left-right direction. According to FIG. 5 (a), the room is divided into a plurality of areas (areas) by boundary lines a1, a2, a3, a4, and areas A1, A2, A3, A4, A5 are arranged from the far side from the indoor unit 1. It is said. In addition, the lower end indoor side of the indoor unit 1 is a reference point 4. Further, according to FIG. 5 (b), the room is divided into a plurality of areas (areas) by dividing the boundaries b1, b2,... B1, B2,..., B9, B10.

  Returning to FIG. 4, the human body position information accumulating unit 103 associates the human body position information output from the human body detection unit 102 with the time information acquired from the time information acquisition unit 101, and divides the human body position into the area of FIG. And carry out accumulation. The area | region which discriminate | determines the human body position information at the time of accumulation for every time slot | zone is demonstrated with reference to FIG.

  FIG. 6 is an explanatory diagram of a region for determining the human body position information of the imaging region shown in FIG. 5 for each time zone. The room is divided into 5 parts in the Z direction and 10 parts in the X direction, and the storage means 120 (see FIG. 3) of the control unit 100 corresponds to this matrix, for example, corresponding to each time every 10 minutes. Storage area is secured.

  Information such as date, day of the week, and time is output from the time information obtaining unit 101 to the storage unit 120, and a storage area corresponding to the day of the week and time may be secured and human body position information may be accumulated. The human body position information may be accumulated while securing a storage area corresponding to the day of the week and the time. Any body position information may be used as long as a memory area corresponding to a certain time zone that can be specified by the time information acquired by the time information acquisition unit 101 is secured and the human body position information is accumulated.

  In the present embodiment, the human body position information uses the position of the face of the occupant. Depending on the driving conditions, the position of the foot may be used. The same applies when there are multiple people in the room.

  Returning to FIG. 4, the time zone-based living area estimation unit 104 uses the data accumulated in the human body position information accumulation unit 103 to estimate the living area in each time zone and obtain the current time acquired from the time information acquisition unit 101. From the information, the living area at the current time and the living area in the future time zone are output. The cumulative degree for each time zone is used for estimating the living area.

  In addition, the control part 100 is air-conditioning with respect to the present position of the human body which is the occupant detected by the human body detection means 102. FIG. Air conditioning control is performed in order to prioritize the comfort level of the current position of the occupant and to perform air conditioning. The control part 100 of this embodiment controls at least one among a wind direction, a wind speed, a wind direction time, and blowing air temperature according to a condition. The human body detection unit 102 detects the human body in the image from the image data that is the output of the imaging unit 4 and outputs human body position information.

  The human body rising detection means 105 compares the human body position information with the past several pieces (predetermined number) of human body position information, and detects that the human body has risen due to the change. Usually, if you stay in one place in your house, you are often sitting on a chair or sofa. When moving from that state to another place, the human body needs to stand up.

  FIG. 7 is an explanatory diagram showing the rising motion of the human body. The movement of the human body when standing up is basically a movement in the upward direction. Usually, however, a related action as shown in FIG. (1) From the sitting state, (2) the upper body is tilted slightly forward, (3) the waist is raised with the center of gravity raised forward, and (4) the operation is to stand up. In this operation, the position of the head is once lowered and then moved upward. At that time, it also moves forward. The position of the head in the sitting state and the standing state is as shown in FIG. Move y1 upward and z1 forward. The amount of movement from the sitting state on the chair varies slightly depending on the height, but y1 is about 30 cm and z1 is about 40 cm.

  When moving from a state of sitting on a sofa, the human body usually rises from a lowering state, and the amount of change tends to increase. The same is true when standing up from the floor. In some cases, such as when sitting on a chair with a table, the amount of forward movement may be reduced by pulling the chair. In order to detect the rising of the human body, the human body rising detection means 105 detects that the human body has risen when the distance from the indoor unit 1 is the same and the height of the head has moved upward by about 30 cm. In the case of a bed, it is the same as that of a chair at the end of the bed, and it is the same as sitting on the floor when in the center of the bed.

  At this time, in order to further improve the accuracy, an imaging result in which the head that appears to be related motion illustrated in FIG. 7A once moves down and then moves upward may be used for detection. When the imaging direction is horizontal, the moving distance in the forward direction may also be used for detection. Further, the speed at the time of rising is considered to be faster than the amount of movement on a normal walk, and the moving speed may be included in the detection means. When the human body rises from the current position, the human body rising detection means 105 estimates that the movement to the next position has been performed.

  Returning to FIG. 4, the next movement location estimation means 106 refers to the current time, and if the estimated living area for each time zone is different from the current position, Presumed to be a moving place. And the air-conditioning control means 107 carries out air-conditioning control of the estimated moving place. Also in this case, at least one of the wind direction, the wind speed, the wind direction time, and the blown air temperature is controlled according to the situation. By performing this control, air conditioning can be performed in advance (pre-emptive) using the rise as a trigger for control that detects the position of a general occupant and performs air conditioning. The person has the effect of not impairing the comfort level.

  Further, since the place where the person moves next is air-conditioned starting from the movement of the person, it is economical without air-conditioning a place where there is no person. If it is prioritized that the living area has been estimated in advance and both the current location and the estimated living area are air-conditioned, if it does not move to the estimated living area, it will air-condition the area where no people are wasted It is not economical.

  Of course, on the other hand, where the current location is intensively air-conditioned, even in areas where there are no people in the room, the temperature is close to the set temperature (for example, a difference of about 2 degrees from the current location). Even if it is air-conditioned in the next moving place estimated after sensing that, it does not impair comfort. For example, when an area where a person is present is air-conditioned at 25 degrees in a 14 tatami room by heating operation, if there is no obstacle, the area where no person is present will warm to about 22 to 23 degrees. By the way, the current location is far from the next location. Or, when there is something that obstructs the flow of wind, such as large furniture, the temperature detection means 108 detects the temperature difference from the current location from the surface temperature of the next location to move to the predetermined location. It is also possible to suppress the temperature difference by air-conditioning in advance so that a temperature difference of a value (for example, 2 degrees) or more does not occur.

  The air conditioner AC of the present embodiment includes an imaging unit 4 that images a room, a human body detection unit 102 that detects the position of a human body based on image information input from the imaging unit 4 every predetermined time, and image information. The human body position information accumulating means 103 for accumulating the human body position information in each time zone from the time information and the human body position information for each area, and the cumulative degree for each area by time zone, Living area estimation means for estimating the living area (for example, living area estimation means 104 for each time zone) and human body rising detection for detecting that the height of the human body is higher than a predetermined value (for example, y1 or more in FIG. 7) Based on the time detected by the means 105 and the human body rising detection means, a movement destination estimation means for estimating the living area estimated for each time zone as the next movement destination (for example, the next movement location) It has a constant section 106), and air conditioning control means 107 for performing air-conditioning control to the estimated destination, a.

  In the air conditioner AC, the human body position information accumulating unit accumulates the human body position information in each time zone for each area, but the present invention is not limited to this. For example, the position of the human body may be accumulated without dividing by time zone, and air conditioning control may be performed based on the result. A modification of each embodiment is as follows.

  The air conditioner AC includes a human body detecting unit 102 that detects the position of a human body, a human body position information accumulating unit 103 that accumulates human body position information detected by the human body detecting unit 102, and a human body detected by the human body detecting unit 102. When the height of the human body is smaller than a predetermined value, air conditioning control is performed based on the position of the human body detected by the human body detecting means 102, and when the height of the human body detected by the human body detecting means 102 is equal to or higher than the predetermined value, An air conditioning control unit 107 that performs air conditioning control based on an area where the cumulative degree of the human body accumulated by the position information accumulating unit 103 is a predetermined value or more may be used.

  As shown in FIG. 7, the height of the human body is equal to or higher than the predetermined value, because there is a difference in height from the floor to the top of the person sitting and standing, the height at which the difference can be discriminated That is all you need. Further, when detecting that the height of the human body is equal to or greater than a predetermined value, it may be detected that the position of the face or head of the human body is equal to or greater than the predetermined value from the floor surface.

  The air conditioner AC is detected by the human body detecting means 102 for detecting the position of the human body, the human body position information accumulating means 103 for accumulating the human body position information detected by the human body detecting means 102, and the human body detecting means 102. When the moving width of the human body is smaller than the predetermined value, the air conditioning control is performed based on the position of the human body detected by the human body detecting means 102, and the moving width of the human body detected by the human body detecting means 102 is equal to or larger than the predetermined value. The air conditioning control means 107 may perform air conditioning control based on an area in which the cumulative degree of the human body accumulated by the human body position information accumulating means 103 is a predetermined value or more.
