Abstract

An air conditioning system includes a collector that obtains user'"'"'s voice data; a voice recognizer that generates character-string data on the basis of the voice data; a memory that stores therein a search table having a standard keyword that indicates the type of sensitivity to the environment inside a room and derivative keywords that indicate a same type of sensitivity as the standard keyword, while indicating different sensitivity levels; an analyzer that determines the type and level of user'"'"'s sensitivity on the basis of the character-string data and the search table; and a controller that outputs a control signal to an adjustment device in an indoor device, the adjustment device adjusting the environment inside a room on the basis of the type and level of sensitivity, which are determined by the analyzer.

Claims

1. An air conditioning system comprising:

a collector to obtain user'"'"'s voice data;

a voice recognizer to generate character-string data on the basis of the voice data;

a memory to store therein a search table having a

standard keyword that indicates a type of sensitivity to an environment inside a room and

derivative keywords that respectively indicate the same type of the sensitivity as the standard keyword while indicating different levels of the sensitivity;

an analyzer to determine a type and a level of the sensitivity of the user on the basis of the character-string data and the search table; and

a controller to output a control signal to an adjustment device in an indoor device, the adjustment device adjusting an environment inside the room on the basis of the type and level of the sensitivity determined by the analyzer;

a room-temperature sensor to detect a temperature inside the room; and

a temperature determiner to determine whether the room is at a predetermined comfortable temperature on the basis of a detection result from the room-temperature sensor, wherein

when the temperature determiner determines that the room is not at the comfortable temperature, the controller controls the adjustment device according to a first control table that represents a relation between the type and level of sensitivity and a control signal for controlling the adjustment device, and

when the temperature determiner determines that the room is at the comfort temperature, the controller controls the adjustment device according to a second control table that is different from the first control table.

6. The air conditioning system according to claim 1, comprising a human sensor to detect a position of the user inside the room, wherein

the controller determines a space for which an environment is to be adjusted on the basis of a detection result from the human sensor.

7. The air conditioning system according to claim 6, wherein

the human sensor detects a body temperature of the user in a noncontact manner.

8. The air conditioning system according to claim 1, comprising:

a camera to obtain image data of the user; and

a second corrector to correct the level of sensitivity on the basis of the image data obtained by the camera, wherein

the controller controls the adjustment device on the basis of the type of sensitivity and the level of sensitivity corrected by the second corrector.

9. The air conditioning system according to claim 8, wherein

the controller

identifies a position of the user inside the room on the basis of the image data obtained by the camera, and

determines a space for which an environment is to be adjusted.

10. The air conditioning system according to claim 1, comprising a remote controller to remotely operate the indoor device, wherein

the collector is provided in the remote controller.

2. (canceled)

3. An air conditioning system comprising:

a collector to obtain user'"'"'s voice data;

a voice recognizer to generate character-string data on the basis of the voice data;

a memory to store therein a search table having a

standard keyword that indicates a type of sensitivity to an environment inside a room and

derivative keywords that respectively indicate the same type of the sensitivity as the standard keyword while indicating different levels of the sensitivity;

an analyzer to determine a type and a level of the sensitivity of the user on the basis of the character-string data and the search table;

a controller to output a control signal to an adjustment device in an indoor device, the adjustment device adjusting an environment inside the room on the basis of the type and level of the sensitivity determined by the analyzer;

a room-temperature sensor to detect temperature inside the room;

a body-temperature sensor to detect body temperature of the user; and

a first corrector to correct the level of sensitivity on the basis of detection results from the room-temperature sensor and the body-temperature sensor, wherein

the controller controls the adjustment device on the basis of the type of sensitivity and the level of sensitivity corrected by the first corrector.

4. The air conditioning system according to claim 3, wherein

the body-temperature sensor detects body temperature of the user in a noncontact manner, and

the controller

identifies a position of the user inside the room on the basis of a detection result from the body-temperature sensor, and

determines a space for which an environment is to be adjusted.

5. The air conditioning system according to claim 3, wherein

the body-temperature sensor is attached to the user, the air conditioning system comprises a communicator that wirelessly communicates with the body-temperature sensor, and

the controller

identifies a position of the user inside the room on the basis of a detection result from the body-temperature sensor received via the communication unit, and

determines a space for which an environment is to be adjusted.

11. The air conditioning system according to claim 3, comprising a human sensor to detect a position of the user inside the room, wherein

the controller determines a space for which an environment is to be adjusted on the basis of a detection result from the human sensor.

12. The air conditioning system according to claim 11, wherein

the human sensor detects a body temperature of the user in a noncontact manner.

13. The air conditioning system according to claim 3, comprising:

a camera to obtain image data of the user; and

a second corrector to correct the level of sensitivity on the basis of the image data obtained by the camera, wherein

the controller controls the adjustment device on the basis of the type of sensitivity and the level of sensitivity corrected by the second corrector.

14. The air conditioning system according to claim 13, wherein

the controller

identifies a position of the user inside the room on the basis of the image data obtained by the camera, and

determines a space for which an environment is to be adjusted.

15. The air conditioning system according to claim 3, comprising a remote controller that remotely operates the indoor device, wherein

the collector is provided in the remote controller.
