Description of the Related Art As a conventional example of a device for detecting the position of a person in a room and automatically controlling the direction of blown air, for example, a device described in Japanese Patent Publication No. 61-38778 (first conventional example). There is.
This is composed of a plurality of light emitting elements installed on the front surface of the air conditioner, a light emitting element and a light reflecting plate installed on the wall surface of the target area. When there is no obstacle in the light traveling direction, the light from the light emitting element is reflected by the light reflecting plate on the wall surface in the corresponding direction and returns to the light receiving element. The presence or absence of an obstacle and its direction are detected by the presence or absence of a signal from this light receiving element,
The deflection plate for adjusting the direction of the air blown from the blower fan of the air conditioner is automatically controlled.

There is an apparatus (second conventional example) described in No. 143441.

可能であった。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the first conventional example, it is necessary to accurately align the optical axis among the light emitting element, the light reflecting plate, and the light receiving element, which makes installation of the apparatus very complicated. In addition, there were restrictions on the locations where they could be installed. Furthermore, since the number of light emitting elements and light receiving elements that can be installed in front of the air conditioner is about 3 to 5 pairs at most, the detection accuracy in the target area is very poor. Moreover, it was impossible to recognize that the obstacle existing on the optical axis is a person.

る。Since the second conventional device measures one point, it is impossible to detect the position of a person. In order to eliminate this drawback, there is also a system in which the pyroelectric infrared one-point detecting element is used for two-dimensional scanning by using a rotating or vibrating optical system. However, the device is large, power consumption is large, and mechanical failure life is short. Therefore, it is unsuitable for mounting on an air conditioner because it has the drawback.

Is also installed. The structure and basic operation of this infrared two-dimensional array sensor will be described with reference to FIG. Pyroelectric thin film
Electrodes 22 and 23 are formed on both surfaces of 21 to form a lateral row. These electrodes 22 and 23 are arranged in a two-dimensional vertical and horizontal manner in a portion corresponding to one pixel. In each pixel forming one column in the horizontal direction, adjacent pixels are alternately wired by electrodes 22 and 23, and pixels in one column are all connected in series. Similar rows are arranged in the vertical direction. Where the pyroelectric thin film
On the entire surface of 21, the polarization direction is from electrode 22 to electrode 23. Therefore, adjacent pixels in each column (eg A,
In B), the polarization directions are reversed and connected. An output signal corresponding to each column is read from the electrode 26 at one end of each column, and the electrode 27 at the other end is grounded. Infrared rays are made incident on each pixel by mechanically scanning the slit 24 corresponding to the lateral width of one pixel in the lateral direction in front of the two-dimensional sensor array.

26から出力される。Along with the movement of the slit 24, the adjacent pixels A, B, C
The amount of infrared rays radiated on the object changes as shown in FIG. The change in the output voltage of the pixel A is proportional to the temperature change of the element, and the temperature change of the element is proportional to the absorbed infrared ray amount. Therefore, assuming that the loss of the heat amount due to heat diffusion is sufficiently small, the output voltage is the infrared ray amount irradiated. In proportion to the integral value of, the waveform becomes as shown in FIG. When the slit 24 further moves and infrared rays irradiate the adjacent pixel B, since the polarization polarity of the pixel B is connected in the direction opposite to that of the pixel A, its output voltage has the opposite polarity to the pixel A Has a delayed waveform as shown in FIG. 4 (c). Similarly, when the pixel C is illuminated, the waveform has a polarity opposite to that of the pixel B as shown in FIG.
Similarly, when the slit 24 moves and infrared rays enter other pixels, the output signal at the electrode 26 has a waveform as shown in FIG. 4 (e). Of this output waveform, t = t 1 ,
The absolute value of each voltage value of t 2 and t 3 is the signal corresponding to the output of each pixel, that is, the amount of infrared rays irradiated to each pixel.
It is output from 26.

次のようなメリットがある。In this infrared two-dimensional array sensor, the output of each row in the horizontal direction has already been converted into a time-series signal, and the output voltage is a signal of a constant frequency.
It has the following advantages.
（１）素子と処理回路間の配線が１列あたり一本で済む

が容易になる。In this embodiment, an infrared two-dimensional array sensor in which 32 × 32 pixels are formed on the same substrate at a pitch of 400 μm,
The air-conditioned space is divided into front, rear, left and right 1024 unit areas as viewed from the air conditioner, and the human body extraction temperature is determined in advance from the heat source in each unit area, and a human body-like object is extracted. Since the size of the extracted object depends on the distance from the sensor, an object within a size range preset according to the position in the image is discriminated as a human body and only the human-like region is selected. . After that, the human body is distinguished from a stationary object such as a TV having a temperature almost equal to that of the human body. In this way, only objects that satisfy conditions such as temperature, size, and movement are recognized as human bodies. In this case, 32 pixels are connected in series per column, and the capacitance of one line is reduced. However, in this embodiment, the pyroelectric material has a thickness of 2 to 3 μm.
Since the thin film with the thickness of is used, the capacitance of each pixel is as large as about 200 pF, and the capacitance of one line can be kept considerably higher than the input impedance of the signal processing circuit of about 2 pF.
The signal voltage is not lowered. The advantage of using a thin film for the pyroelectric body in the present invention also appears in this point. In addition, there is a material (PbLaTiO 3 system) that has the same polarization axis as the material of the pyroelectric thin film at the same time as it is formed. It will be easier.

存するきめ細やかな快適空調が実現出来たわけである。Next, with reference to FIG. 5, the control of the blowing air based on the detection result of the infrared two-dimensional array sensor 7 will be described. When the detection signal of the human body in the room is input from the infrared two-dimensional array sensor 7 to the signal processing device 8, it is determined whether or not the person is a person based on the detected temperature and shape, and when it is determined that the person is the person. Inputs the processed signal to the control device 9 as human body position information. The control device 9 adjusts the direction and intensity of the blown air to determine the flap deflection angle and the rotation speed of the blower fan that can provide a comfortable air conditioning effect. In the case of wind direction control, the determined flap deflection angle signal is further determined. The flap deflection angle signal thus determined is output to the step motor control device 10. The flap 6a is controlled by a step motor 11 according to the deflection angle signal. By the functions of the controlled flap and the blower fan, for example, a strong wind is directly sent to a position where a person is present, or conversely, a weak wind is sent so as to avoid the person. Also,
It is also possible to send air-conditioned air in sequence when there are multiple people. In this way, delicate and comfortable air conditioning that depends on the location of people can be realized.
尚、ここで空調対象空間を単位領域に分割する数は32

あってもその効果は十分に発揮できる。Note that the number of subdivided air-conditioned spaces is 32 here.
The number of divisions is not limited to x32, and the optimum number of divisions is selected according to the size and shape of the air-conditioned space. For example, in the case of a living room of 6 to 10 tatami mats, the effect can be sufficiently exerted even if the infrared two-dimensional array sensor composed of 8 × 8 unit pyroelectric sensors is used and divided into 64 unit areas.
