The invention discloses a space smell adjusting system. The system comprises an environment information acquisition assembly, an information processing device and a smell generation device; the environment information acquisition assembly is used for acquiring environment information; the information processing device is in data interaction connection with the environment information acquisition device; the smell generating device comprises a plurality of basic smell storage boxes, a smell blending assembly and a gas conveying opening. And the smell blending assembly adjusts the output quantities of the multiple basic smell storage boxes according to the output smell component information to generate a final smell, and the gas conveying opening is formed in a to-be-adjusted space and outputs the final smell to the to-be-adjusted space. According to the scheme, the smell atmosphere of the external environment can be simulated and manufactured in the closed space and the semi-closed space by recognizing the external information, and the system can manufacture the smell atmosphere meeting the information requirement in the closed space and the semi-closed space according to the indoorvideo information, the voice information, the smell information and the like.

The invention provides the system and the method capable of testing acuity of sense of smell of animals objectively and efficiently.

The invention discloses a virtual smell generation device and an apparatus. The device comprises a first upper end cover, a second upper end cover, a first smell generation module, a second smell generation module, a first lower end cover, a second lower end cover, a first shouldering support frame front end, a second shouldering support frame front end, a first shouldering support frame rear end,a second shouldering support frame rear end and a connecting plate. The connecting plate controls the smell selection, smell emission time, smell continuous emission time, smell emission concentration and the like of the smell emitted by the first smell generation module, and controls the smell selection, smell emission time, smell continuous emission time, smell emission concentration and the like of the smell emitted by the second smell generation module. By means of the mode, at least two smells can be generated, and then the corresponding smells can be generated in different virtual scenes.

Images of farm animal products taken by CCD camera through image acquisition card are transferred to computer. Under certain condition (temperature, humidity and flow rate), smells emitted from farm animal products through mini pump with no oil are sucked into reaction chamber, where signals are generated by array of gas sensor. The said signals through conditioning circuit, A / D acquisition card are transferred to computer. Computer for simulating human brain to treat vision data and smell data carries out syncretizing and pattern recognition processing. Combining with experts' knowledge in knowledge base as well as experiences, computer makes judgment for qualities of garden spgarden stuff, meat and corns etc. synthetically.

The invention relates to the field of household appliances, in particular to a lighting device and a control method thereof. The lighting device comprises a shell and a lamp main body.

The invention provides a visual perception type water quality early warning system and method using olfaction signal enhancement. The method comprises the steps of: carrying out continuous monitoring on the characteristics of a target fish behavior through a visual model, and judging whether the target fish behavior is abnormal or not in real time; activating further detection when a detection result contains an abnormal stress behavior, and performing olfaction detection on the fish water environment with the stress behavior; and correcting a data set by using an abnormal water quality component result of the olfaction detection and the calculated characteristic value of the target fish behavior, and storing the data set in an experience pool, so as to continuously correct the behavior abnormality problem of the target fish caused by harmful compounds contained in the water. The characteristics of the target fish behavior monitored by the visual model continuously fit the behavior characteristic curve of fishes in a real water environment. According to the method, the perception ability of the visual model in vision is continuously enhanced by using the olfaction signal, the complementarity of heterogeneous data signals is fully played, the accuracy, the real-time performance and the high efficiency of the water quality early warning model are improved, and the consumption of time, space and human resources is reduced.
