System for measuring odor and method for measuring odor using the same

A method of measuring odor data, the method comprising:

• injecting a gas into an odor measurement chamber;
• monitoring first odor data of the gas for a sensing time period of an odor sensor disposed in the odor measurement chamber when the odor sensor senses an odor of the gas;
• controlling an inlet valve and an outlet valve mounted in an inlet and an outlet of the odor measurement chamber, respectively, to close in response to a variation in the monitored first odor data being equal to or greater than a reference value;
• and
• acquiring second odor data of the gas, sensed by the odor sensor in a state of confining the gas in the odor measurement chamber by closing the inlet valve and the outlet valve, as actual odor data.

A system for measuring odor data, the system comprising:

• an odor measurement chamber comprising a gas inlet and a gas outlet located at respective end portions of the odor measurement chamber;
• an inlet valve mounted in the gas inlet;
• an outlet valve mounted in the gas outlet;
• a first odor sensor and a second odor sensor disposed in the odor measurement chamber;
• and
• a controller configured to monitor first odor data of a gas injected into the odor measurement chamber for a sensing time period of the first odor sensor, to control the inlet valve and the outlet valve to close in response to a variation in the monitored first odor data being equal to or greater than a reference value, and then to acquire second odor data of the gas sensed by the second odor sensor as actual odor data.

A method of measuring odor data, the method comprising:

• injecting a gas into an odor measurement chamber;
• monitoring first odor data of the gas for a sensing time period of a first odor sensor disposed in the odor measurement chamber in response to the first odor sensor sensing the odor of the gas;
• controlling an inlet valve and an outlet valve mounted in an inlet and an outlet of the odor measurement chamber, respectively, to close in response to a variation in the monitored first odor data being equal to or greater than a reference value;
• and
• acquiring second odor data of the gas as actual odor data, the second odor data acquired by sensing by a second odor sensor disposed in the odor measurement chamber in a state of confining the gas in the odor measurement chamber by closing the inlet valve and the outlet valve.

• an odor measurement chamber comprising a gas inlet and a gas outlet located at respective end portions of the odor measurement chamber;
• an inlet valve mounted in the gas inlet;
• an outlet valve mounted in the gas outlet;
• a general-purpose odor sensor and at least three particular odor sensors disposed in the odor measurement chamber;
• and
• a controller configured to monitor first odor data of a gas injected into the odor measurement chamber for a sensing time period of the general-purpose odor sensor, to control the inlet valve and the outlet valve to close in response to a variation in the monitored first odor data being equal to or greater than a reference value, and to acquire, as actual odor data, second odor data of the gas sensed by one particular odor sensor of the at least three particular odor sensors.
