Embodiment.
FIG. 1 is a configuration diagram of an air conditioner control device according to an embodiment of the present invention. 1 includes an air conditioner control device 20 according to an embodiment of the present invention, an air conditioner 10 controlled by the air conditioner control device 20, and an air conditioner for performing air conditioning control of the air conditioner 10. A remote controller 30 that outputs setting information 30a is shown.

  The air conditioner control device 20 includes a sensor unit 22 and a control unit 23. In addition, the air conditioner control device 20 includes a storage unit 24 that stores the air conditioning setting information 30a, the detection information 22a, and the operation table 200.

  The sensor unit 22 detects human movement, room temperature, and human body temperature and outputs detection information 22a. The sensor unit 22 includes a temperature detection unit that detects the position and temperature of the heat source in the indoor space 100, and an imaging unit that images the indoor space 100 and a person.

  As the temperature detection unit, a thermopile or an infrared sensor can be exemplified. An example of the imaging unit is a CCD (Charge Coupled Device) camera. The imaging unit is arranged so that a wider range of the room can be seen with the same angle of view, images the indoor space 100 over time, and outputs the captured image as image information. The temperature information detected by the temperature detection unit and the image information output from the imaging unit are input to the control unit 23 as detection information 22a.

  The control unit 23 generates control amount information 23-1 for performing air conditioning control of the air conditioner 10 based on the detection information 22 a and the air conditioning setting information 30 a. Specifically, the control unit 23 includes an information acquisition unit 23a that acquires the detection information 22a and the air conditioning setting information 30a, and a control amount information generation unit 23b.

  Based on the information acquired by the information acquisition unit 23a, the control amount information generation unit 23b estimates the human gesture from the relative position change of each part of the human body existing in the indoor space 100, and performs control corresponding to the human gesture. Quantity information 23-1 is generated. The control amount information 23-1 is control information for controlling a controlled device mounted on the air conditioner 10 so as to reduce a person's discomfort according to a person's gesture. Details of the human gesture estimation operation and the control amount information 23-1 generation operation will be described later.

  The controlled devices include various devices such as a fan motor, a compressor, and a propeller fan mounted on the air conditioner 10. In FIG. 1, as an example of the controlled device, an air conditioning control unit 11, an air outlet 12, and a louver 13 that is installed at the air outlet 12 and changes the wind direction are illustrated.

  FIG. 2 is a flowchart for explaining the operation of the air conditioner control apparatus according to the embodiment of the present invention. FIG. 3 is a flowchart for explaining the analysis operation in S4 shown in FIG. In S1 shown in FIG. 2, the sensor unit 22 outputs detection information 22a. In S2, the control unit 23 acquires the detection information 22a and the air conditioning setting information 30a. In S3, the storage unit 24 outputs the detection information 22a and the air conditioning setting information 30a. Remember. In S4, the control amount information generation unit 23b of the control unit 23 analyzes a human gesture.

  In FIG. 3, the control amount information generation unit 23b detects the position of each person existing in the indoor space 100 based on the detection information 22a. Specifically, the control amount information generation unit 23b detects the position of each person based on image information output from the imaging unit constituting the sensor unit 22 at regular intervals (S41). This detection result includes the coordinates of the centers of the parts, such as the face, torso, both arms, and both legs, that make up each detected human body, and the sizes of these parts. This detection result is converted from a coordinate system on the screen specified by the number of pixels on the imaging screen to a coordinate system in the real space.

  Next, the control amount information generation unit 23b compares the first trajectory on the coordinates of both arms based on the detected face and body with a plurality of second trajectories stored in advance in the storage unit 24 ( S42). The plurality of second trajectories are reference information associated with each of a plurality of human gestures, and the human gesture includes a motion of wiping the face with a hand when the temperature is high, such as in summer, or in winter Thus, the operation of rubbing the body by hand when the temperature is low can be exemplified. As a result of the comparison between the first trajectory and the plurality of second trajectories, the controlled variable information generation unit 23b estimates the human gesture corresponding to the second trajectory having a high correlation with the first trajectory (S43). ).

  FIG. 4 is a diagram showing an example of an operation table stored in the storage unit shown in FIG. In the operation table 200, a gesture code 201 for identifying a human gesture and control amount information 202 are associated with each other. The control amount information 202 is information indicating respective adjustment amounts of temperature, humidity, and air volume corresponding to the gesture code 201.

Specific examples of the gesture code 201 and the control amount information 202 will be described. The gesture code 201 of the code “001” corresponds to an operation of wiping the face with a hand when the temperature is high as in summer. The gesture code 201 corresponding to the code “001” includes temperature information in which the temperature of the indoor space 100 is −X ° C. with respect to the set temperature, and humidity information in which the humidity of the indoor space 100 is −Y% with respect to the set humidity. And air volume information in which the air volume blown out from the air conditioner 10 is + Zm ³ / h with respect to the set air volume is associated with each other. The gesture code 201 of the code “002” corresponds to an operation of rubbing the body by hand when the temperature is low as in winter. The gesture code 201 corresponding to the code “002” includes temperature information for setting the temperature of the indoor space 100 to + X ° C. with respect to the set temperature, and the air volume blown from the air conditioner 10 to + Zm ³ / h with respect to the set air volume. Is associated with the air volume information.

  The control amount information generation unit 23b refers to the operation table 200, and converts the information indicating the temperature, humidity, and air volume included in the control amount information 202 corresponding to the estimated gesture into the control amount information 23-1 shown in FIG. To the air conditioner 10 (S5).

The air conditioning control unit 11 that has received the control amount information 23-1 controls the controlled devices mounted on the air conditioner 10 in an integrated manner. That is, the air conditioning control unit 11 that has received the control amount information 23-1 corresponding to the code “001” reduces the room temperature by −X ° C. with respect to the set temperature, reduces the room humidity by −Y% with respect to the set humidity, Air conditioning operation is performed so that the air volume is increased by + Zm ³ / h with respect to the set air volume. That is, the air conditioning operation is performed so as to reduce human discomfort according to the human behavior estimated by the control unit 23.

  In the present embodiment, the control unit 23 determines the operation mode set by the remote controller 30 by using the air conditioning setting information 30a in addition to the detection information 22a. That is, when the air conditioner 10 is set to the cooling mode, the control unit 23 determines that the human gesture detected by the sensor unit 22 is an operation in summer, and the air conditioner 10 is set to the heating mode. If it is, the gesture of the person detected by the sensor unit 22 is determined to be a winter operation. By determining in this way, it is possible to determine the gesture code 201 corresponding in more detail as compared with the case where the air conditioning setting information 30a is not used, and it is possible to realize an air conditioning operation more suitable for human gestures.

  Moreover, the control part 23 specifies a person's position based on the detection information 22a detected by the sensor part 22, includes the positional information regarding the specified person's position in the control amount information 23-1, and outputs it to the air conditioner 10. You may comprise as follows. With this configuration, the air-conditioning control unit 11 that has received the control amount information 23-1 including the position information is configured so that the air blown from the air outlet 12 is detected by the sensor unit 22 based on the control amount information 23-1. The direction of the louver 13 can be changed so as to hit the person detected by the above, and a more suitable air-conditioning operation can be realized depending on the gesture of the person.

  As described above, the air conditioner control device according to the present embodiment is a sensor unit that detects the room temperature of the indoor space in which the air conditioner is installed, the body temperature of the person existing in the indoor space, and the movement of the person. And estimating the human gesture in the indoor space based on at least the detection information on the room temperature, body temperature and movement detected by the sensor unit, and the air conditioning environment in the indoor space reduces the human discomfort according to the human gesture. Control amount information for performing air-conditioning control so as to reduce is generated. With this configuration, an air-conditioning environment suitable for various gestures can be provided.
