Environment control system, environment control method, and recording medium

Abstract

An environment control system is an environment control system that controls an environment of a target space. The environment control system includes: an obtainer that obtains biological information of a person present in the target space and environmental information of the target space; an estimator that estimates, based on the biological information and the environmental information obtained by the obtainer, a position of the person in the target space and a condition level indicating a level of comfort felt by the person in regard to the environment; a generator that generates, based on the position and the condition level of the person estimated by the estimator, a control signal that controls an operation of a device provided in the target space; and an outputter that outputs the control signal generated by the generator to the device.

1 . An environment control system that controls an environment of a target space, the environment control system comprising:
 an obtainer that obtains biological information of a person present in the target space and environmental information of the target space;   an estimator that estimates, based on the biological information and the environmental information obtained by the obtainer, a position of the person in the target space and a condition level indicating a level of comfort felt by the person in regard to the environment;   a generator that generates, based on the position and the condition level of the person estimated by the estimator, a control signal that controls an operation of a device provided in the target space; and   an outputter that outputs the control signal generated by the generator to the device.   
     
     
         2 . The environment control system according to  claim 1 , wherein
 the estimator stores, as history information, the position and the condition level of the person estimated in a storage.   
     
     
         3 . The environment control system according to  claim 2 , wherein
 the estimator estimates the condition level based on the biological information, the environmental information, and the history information.   
     
     
         4 . The environment control system according to  claim 2 , wherein
 when an absolute value of a difference between the condition level estimated by the estimator and a previous condition level estimated one before the condition level is greater than a threshold, the generator generates a control signal that controls an operation of the device to make the absolute value of the difference smaller than the threshold.   
     
     
         5 . The environment control system according to  claim 4 , wherein
 when the absolute value of the difference is greater than the threshold, the outputter outputs the control signal generated by the generator to the device.   
     
     
         6 . The environment control system according to  claim 2 , wherein
 the estimator:
 estimates the condition level of each of people including the person; and 
 derives a standard index of the condition level based on the condition level of each of the people estimated, and stores the standard index derived in the storage. 
   
     
     
         7 . The environment control system according to  claim 1 , wherein
 a sensor that obtains the biological information and the environmental information includes, out of an infrared sensor, a temperature sensor, a humidity sensor, a gas sensor, a floating matter sensor, an illuminance sensor, and a color temperature sensor, at least the infrared sensor.   
     
     
         8 . An environment control method that controls an environment of a target space, the environment control method comprising:
 obtaining biological information of a person present in the target space and environmental information of the target space;   estimating, based on the biological information and the environmental information obtained in the obtaining, a position of the person in the target space and a condition level indicating a level of comfort felt by the person in regard to the environment;   generating, based on the position and the condition level of the person estimated in the estimating, a control signal that controls an operation of a device provided in the target space; and   outputting the control signal generated in the generating to the device.   
     
     
         9 . A non-transitory computer-readable recording medium for use in a computer, the recording medium having thereon a computer program for causing the computer to execute the environment control method according to  claim 8 .
