Air-Conditioning System

Abstract

This air-conditioning system comprises: a local settings reception unit that accepts local settings changed from specified system settings by a local setting terminal that allows users in an area to set the air-conditioning of the area; a number-of-people-in-area detecting unit that detects the number of people in the area; and an air-conditioning control instruction unit that outputs, to an air-conditioning control system, an instruction to maintain the local settings accepted by the local settings reception unit until the elapsed time from the time when the local settings are changed in the area reaches a predetermined setting time, and, when the elapsed time exceeds the setting time, outputs, to the air-conditioning control system, an instruction to return to the system settings that are set on the basis of the number of people detected by the number-of-people-in-area detecting unit, and/or the type of area.

1 . An air-conditioning system that controls operation of an air conditioner to air-condition an inside of an area, the air-conditioning system comprising:
 a local settings reception unit that accepts local settings changed from specified system settings by a local setting terminal that allows a user in the area to set air-conditioning in the area;   a number-of-people-in-area detecting unit that detects a number of people in the area; and   an air-conditioning control instruction unit that outputs, to an air-conditioning control system, an instruction to maintain the local settings accepted by the local settings reception unit until an elapsed time from a time when the local settings are changed in the area reaches a predetermined setting time, and, when the elapsed time exceeds the setting time, outputs, to the air-conditioning control system, an instruction to return to the system settings that are set based on at least one of the number of people detected by the number-of-people-in-area detecting unit and a type of the area.   
     
     
         2 . The air-conditioning system according to  claim 1 , further comprising
 an area setting table in which the system settings preset for each area, the local settings changed in the area, a time when the local settings are set in the area, and the setting time are specified for each area, wherein   the air-conditioning control instruction unit compares the elapsed time with the setting time based on the area setting table, and outputs an instruction to maintain the local settings or an instruction to return to the system settings to the air-conditioning control system.   
     
     
         3 . The air-conditioning system according to  claim 2 , wherein
 the number-of-people-in-area detecting unit includes a sensor data acquisition unit that acquires sensor data output from a sensor provided in the area, and a sensor data analysis unit that obtains the number of people in the area by using the sensor data,   the number of people in the area obtained by the sensor data analysis unit is used by a prediction unit to output a prediction result in which a change in at least one of temperature and the number of people after a lapse of a predetermined time in the area is predicted, and   the air-conditioning control instruction unit changes the system settings based on the prediction result, and outputs an instruction to maintain the system settings or an instruction to return to the system settings to the air-conditioning control system.   
     
     
         4 . The air-conditioning system according to  claim 3 , comprising:
 an area information table in which area information including at least a type of the area and a position of the area in a building is specified for each area; and   a sensor data registration table in which information acquired from the sensor data, the number of people in the area, and the prediction result are registered, wherein   the prediction unit predicts a change in at least one of temperature and the number of people after a lapse of a predetermined time in the area based on the area information table and the sensor data registration table.   
     
     
         5 . The air-conditioning system according to  claim 4 , wherein
 the sensor is a camera that captures an image of an inside of the area,   the sensor data is image data generated by the camera, and   the sensor data analysis unit obtains the number of people in the area based on the image data.   
     
     
         6 . The air-conditioning system according to  claim 4 , wherein
 the sensor is an environment sensor that measures environment information of at least one of temperature and humidity in the area,   the sensor data is environment data generated by the environment sensor, and   the sensor data analysis unit obtains the number of people in the area based on the environment data.   
     
     
         7 . The air-conditioning system according to  claim 5 , comprising
 a system settings reception unit that accepts the system settings preset for each area input from a system setting terminal and writes the accepted system settings in the area setting table for each area, wherein   the air-conditioning control instruction unit outputs an instruction of the system settings for each of a plurality of the areas based on the area setting table.   
     
     
         8 . The air-conditioning system according to  claim 7 , wherein
 the setting time is preset by the system setting terminal while the system settings reception unit is activated, or set by the local setting terminal while the local settings reception unit is activated.
