Air-conditioning system using temperature sensor tag

Abstract

An air-conditioning system includes: an air conditioner; a communication unit performing wireless communication; one or more wireless tags (WTs) performing wireless communication and temperature measurement, the WTs being supplied with electric power through the wireless communication; and a control unit controlling the air-conditioning system. The WTs are located in an object on which a person is to be seated or lie in a predetermined space, and the control unit causes the air conditioner to adjust a temperature of the space on a basis of a first temperature in a case where at least one of a strength of a signal received from one of the WTs by the communication unit through the wireless communication or response time of the wireless communication between one of the WTs and the communication unit has changed, the first temperature being measured by the one of the WTs and acquired via the communication unit.

What is claimed is: 
     
         1 . An air-conditioning system comprising:
 an air conditioner configured to perform adjustment of a temperature of a predetermined space;   a communication unit configured to perform wireless communication;   one or more wireless tags configured to perform wireless communication and temperature measurement, the one or more wireless tags being configured to be supplied with electric power through the wireless communication; and   a control unit configured to control the air-conditioning system, wherein   the one or more wireless tags are located in an object on which a person is to be seated or lie in the space, and   the control unit is configured to cause the air conditioner to perform the adjustment of the temperature of the space on a basis of a first temperature in a case where at least one of a strength of a signal received from one of the one or more wireless tags by the communication unit through the wireless communication or response time of the wireless communication between one of the one or more wireless tags and the communication unit has changed, the first temperature being measured by the one of the one or more wireless tags and acquired via the communication unit.   
     
     
         2 . The air-conditioning system according to  claim 1 , wherein
 the control unit is configured to:   control the adjustment of the temperature of the space on the basis of the first temperature in a case where the strength of the signal falls within a predetermined first range; and   acquire a second temperature at a predetermined position distant from the object and control the adjustment of the temperature of the space on a basis of the second temperature in a case where the strength of the signal falls within a second range higher in strength than the first range.   
     
     
         3 . The air-conditioning system according to  claim 2 , wherein
 the object is a chair, and   one of the one or more wireless tags is located on a seating surface of the chair.   
     
     
         4 . The air-conditioning system according to  claim 3 , wherein
 the one or more wireless tags include a first wireless tag and a second wireless tag,   the first wireless tag is located on the seating surface of the chair, and   the second wireless tag is located in the chair at a position other than the seating surface.   
     
     
         5 . The air-conditioning system according to  claim 3 , wherein
 the one or more wireless tags include only a first wireless tag, and   the first wireless tag is located on the seating surface of the chair.   
     
     
         6 . The air-conditioning system according to  claim 4 , wherein
 the first wireless tag is located in a first region out of the first region on the seating surface and a second region surrounding the first region, and   the second region is in a shape along an outline of the seating surface.   
     
     
         7 . The air-conditioning system according to  claim 1 , further comprising a temperature sensor connected to the control unit, the temperature sensor being configured to measure a temperature of the space, wherein
 the control unit is configured to acquire the temperature measured by the temperature sensor and control the adjustment of the temperature of the space on a basis of the temperature measured by the temperature sensor in a case where no change in the at least one of the strength of the signal or the response time has been detected.
