Embodiment 2

[0050] The odor detection system provided in this embodiment includes an odor detection device and a corresponding execution device.

[0051] Such as image 3 As shown, the odor detection device includes an odor collection device 301, a sensor array 302, and a control unit 303, and the control unit 303 includes a calculation module 303a, a storage module 303b, and an odor comparison module 303c; the execution device includes a wine cabinet display device 304 and a wine cabinet alarm device 305 , the gas sensor used in the sensor array 302 for detecting the alcohol gas in the wine cabinet and the corresponding odor collection device 301 are set in the wine cabinet.

[0052] The smell collection device 301 collects the alcohol smell in the environment in the wine cabinet, and sends it to the corresponding gas sensor in the sensor array 302, and the corresponding gas sensor obtains the smell map of the specific smell, and sends the smell map of the specific smell to the computing m...

Embodiment 3

[0055] The odor detection system provided in this embodiment includes an odor detection device and a corresponding execution device.

[0056] Such as Figure 4 As shown, the odor detection device includes an odor collection device 401, a sensor array 402 and a control unit 403, and the control unit 403 includes a calculation module 403a, a storage module 403b, and an odor comparison module 403c; A gas sensor for detecting a specific smell in the kimchi cabinet and a corresponding smell collection device 401 are arranged in the kimchi cabinet.

[0057] The specific smell in this example is the sour smell of kimchi.

[0058] The odor collecting device 401 collects the specific odor in the environment in the kimchi cabinet, and sends it to the corresponding gas sensor in the sensor array 402, and the corresponding gas sensor obtains the odor spectrum of the specific odor, and sends the odor spectrum of the specific odor to the computing module 403a, the calculation module 403a ...

Embodiment 1

[0086] Such as Figure 9 As shown, the odor detection method provided in this embodiment includes:

[0087] Step S101: the sensor array acquires an odor map of a specific odor;

[0088] Step S102: The control unit compares the odor map with the odor model of the specific odor, and calculates the concentration value of the specific odor according to the comparison result; and processes and analyzes the concentration value of the specific odor, and generates a corresponding control signal to send to an external actuator.

[0089] Optionally, before step S101, it also includes:

[0090] Step S100: the odor collection device collects a specific odor, and sends the specific odor to the sensor array.

[0091] Specifically, the sensor array includes at least one gas sensor for measuring the concentration value of a specific odor, which are respectively arranged in a corresponding environment to be detected. The environment to be detected can be in a refrigerator, in a wine cabinet, ...

Abstract

The invention provides a smell detection device, a detection system and a detection method. The smell detection device comprises a sensor array and a control unit. The sensor array obtains a smell spectrum of a specific smell. The control unit compares the smell spectrum and a smell model of the specific smell, calculates the concentration of the specific smell according to the comparison result, processes and analyzes the concentration, and generates a corresponding signal controlling a corresponding executive device. For example, a user can know changes of food in a refrigerator, a wine cabinet and a pickled vegetable cabinet in real time. Automatic adjusting of household appliances such as air conditioners and refrigerators during environment changes can be achieved, thus effectively increasing the intelligentizing level of the household appliances.

Description

technical field [0001] The invention relates to gas sensing technology, in particular to an odor detection device, detection system and detection method. Background technique [0002] Existing household appliances such as refrigerators, wine cabinets, kimchi cabinets, ovens, etc. can only store food, and users cannot know the changes in food in real time, so users cannot deal with changes in food in time; When the environment changes, it cannot be adjusted automatically, and it can only be operated manually. [0003] The degree of intelligence of the above-mentioned household appliances is relatively low, which cannot meet people's demand for intelligent household appliances. Contents of the invention [0004] Aiming at the problem of low intelligence level of current household appliances, the present invention provides an odor detection device, detection system and detection method with high intelligence level. [0005] An odor detection device, comprising: [0006] Se...
