  FIG. 1 is a diagram showing a configuration of an embodiment of an olfactory information encoding apparatus according to the present invention.

  Referring to FIG. 1, the olfactory information encoding apparatus includes a database unit 100, a scent analysis unit 110, and an encoding unit 120. The database unit 100 includes a scent-chemical component database 102, a chemical component code database 104, and a scent code database 106, the scent analysis unit 110 includes a component analysis unit 112 and a correction unit 114, and the encoding unit 120 has a center. A scent analysis unit 122, a visualization unit 124, and a packet generation unit 126 are provided.

  In the scented substance, the scent component content is extremely small, 0.05% for green tea, 0.025% for black tea, and about 0.02% for fresh leaves. Therefore, when analyzing a scent in real time as in the present invention, it is very difficult to accurately analyze the entire constituent components in the entire scented material.

Therefore, in the present invention, in order to overcome such difficulties, a large amount of scent substances are collected off-line, and the collected scent substances are analyzed by a conventional scent-chemical constituent analyzer to quantitatively analyze the chemical constituents. A fragrance-chemical component database is generated based on the values. Table 1 shows elements of scent data stored in the scent-chemical component database 102.

  The fragrance-chemical component database 102 classifies fragrance data composed of quantitative values of chemical components obtained by analyzing a predetermined fragrance into a central fragrance component and a peripheral fragrance component based on the amount of the chemical component. save. The fragrance-chemical component database 102 selects a chemical component including the maximum amount as a central fragrance component from among the chemical components constituting the fragrance, selects other chemical components as peripheral fragrances, and sequentially stores them according to the amount. To do.

  The scent-chemical component database 102 is objective and applies a general code system. For this purpose, the database unit 100 includes, in addition to the scent-chemical component database 102, a scent code database 106 that includes codes for scents, and a chemical component code database 104 that includes codes for chemical components.

  The chemical component code database 104 stores systematic codes assigned to various chemical components. The scent code database 106 systematically assigns and stores codes for scents included in a predetermined domain. The scent-chemical component database 102 stores the constituent chemical components for the scent of a predetermined domain using the scent code defined in the scent code database 106 and the chemical component code defined in the chemical component code database 104. To do. Thereby, it is possible to express the constituent chemical components of the predetermined scent in a systematic and consistent code. The generation of the scent code database 106 will be described in detail with reference to FIGS.

  The scent analysis unit 110 quantifies the result obtained by analyzing the scent of the predetermined substance using the database unit 100. Since a general substance contains a very small amount of a scent component, the analysis result of the actually measured scent is corrected using the database unit 100 that stores a value quantified in advance for each scent.

  Specifically, the component analysis unit 112 analyzes the chemical components constituting the scent of the predetermined substance and grasps the content of each chemical component. And the correction | amendment part 114 measures the similarity of the chemical component analyzed by the component analysis part 112, and the fragrance data of the database part 100, and searches the fragrance data with the highest similarity with the analyzed chemical component. Then, the correction unit 114 corrects the value of the analyzed chemical component with the quantified value of the searched scent data.

  A variety of similarity measurement algorithms can be used to compare the similarity between the analyzed chemical component and the scent data in the database. Here, a filtering algorithm will be described as an example.

  First, primary filtering is performed to extract fragrance data that matches a certain percentage or more of the analyzed chemical component type from the fragrance-chemical component database 102. And the secondary filtering which extracts the fragrance data which compares the component amount of center fragrance | flavor among the extracted fragrance data, and exists in a fixed error range is performed. Finally, among the scent data subjected to the secondary filtering, the scent data having the highest similarity is selected by comparing the similarities of the components of the peripheral scent.

  That is, the correction unit 114 extracts scent data whose content and similarity of the analyzed chemical component are equal to or higher than a certain critical value from the scent-chemical component database, and the amount of the chemical component analyzed by the extracted scent data value. To change.

  However, if the scent data whose similarity to the analyzed chemical component is not less than a certain critical value does not exist in the scent-chemical component database 102, the correction unit 114 recognizes the analyzed chemical component as a new scent. The scent-chemical component database 102 is separately displayed and stored, or is stored in a separate database (not shown). That is, since the chemical component analyzed in real time by the scent analysis unit 110 is a little inaccurate information, it is not used like the scent data quantified and stored in the scent-chemical component database 102, but simply a scent. -Used to assist the chemical component database 102.

  The encoding unit 120 separates the constituent chemical components of the scent measured and quantified by the scent analysis unit 110 into a central scent component and a peripheral scent component, and a central scent component and a peripheral scent component chemical component. Convert the amount of to grayscale. The gray scale is obtained by visually matching the level of color intensity expressed in white and black and gray in between, to the luminance level.

  Specifically, the central scent analysis unit 122 selects the maximum amount of chemical components as the central scent component among the analyzed chemical components, and selects other chemical components as the peripheral scent components. Here, the central scent component is a chemical component indicating the current state of a scented substance, green leaf alcohol, which is the central component of the green scent of young leaves, geraniol of esters and roses, a bitter astringent smell Indole and other compounds such as enols and lily of the valley with light and refreshing scents such as linator, and peripheral incense components refer to chemical components other than the central incense components.

  The visualization unit 124 converts the individual amounts of the chemical components of the central scent component and the peripheral scent component selected by the central scent analysis unit 122 into color information such as gray scale and displays it. Based on such visualized olfactory information, information such as food rot and fruit maturity can be grasped. In particular, even if there is no scent generator in a space such as the Internet, it is possible to grasp the scent state of food products currently inquired on the Internet through color information.

  The packet generation unit 126 generates the value of the central scent component and the peripheral scent component of the scent into a packet that can be transmitted via the network.

  FIG. 2 is a diagram illustrating a packet structure for transmitting olfactory information according to the present invention.

Referring to FIG. 2, the packet 200 includes an SmCode 210, a CentSmCode 210, a CentGray 230, an OtherSmNum 240, a MinOtherSmNum 250, an OtherSmCode 260, and an OtherGray 270 field. The meaning of each field will be described with reference to Table 2.

  Here, the SmCode field 210 is a field for recording a scent code value, and the scent code must be given in an objective and general code system for coding and transmission of the code. A method for constructing the scent code list by domain will be described in detail with reference to FIGS.

  The CentSmCode 220 and OtherSmCode 260 fields are fields for recording code values for chemical components, and the CentSmCode 220 and OtherSmCode 260 are encoded using the chemical component database 104. The OtherSmNum field 240 is a field for recording the number of peripheral incense having an amount equal to or greater than a certain critical value among the chemical components obtained by analyzing the fragrance, and is necessary for transmitting information on the peripheral incense in a packet. Used when allocating 260 slots. The MinOtherSmNum field 250 is a field for recording the minimum amount of chemical component used when analyzing the chemical component. The CentGray 230 and the OtherGray field 270 are fields for storing values obtained by changing the quantitative amounts of the chemical components of the central fragrance and the peripheral fragrance to gray scale.

  FIG. 3 is a flowchart showing the flow of an embodiment of the olfactory information encoding method according to the present invention.

  Referring to FIGS. 1 and 3, the scent analysis unit 110 analyzes a predetermined scent substance and measures the content of chemical components constituting the scent (S300). In the scent-chemical component database 102, scent data quantified by analyzing scent in advance through an analyzer is stored. Here, the scent data is separated into a central incense component and a peripheral incense component and stored.

  After analyzing the chemical component of the scent in real time, the scent analysis unit 110 searches the scent-chemical component database 102 for scent data whose similarity with the analyzed chemical component is a certain critical value or more (S305, S310), The amount of the chemical component analyzed with the searched scent data value is corrected (S315). Thereby, the content of the scent component in the substance is small, and a slightly inaccurate analysis result can be corrected.

  If the scent data whose similarity is equal to or higher than a certain critical value does not exist in the scent-chemical component database 102 compared to the analyzed chemical component (S310), the analyzed chemical component is set as a new scent, The scent-chemical component database 102 or a separate database (not shown) is stored (S320). At this time, since the analysis result of the chemical component analyzed in real time is not the result of accurate quantification, it is desirable to use it as a role to assist the fragrance-chemical component database 102.

  The encoding unit 120 classifies the chemical component value corrected with the value quantified based on the fragrance-chemical component database 102 into a central incense component and a peripheral incense component (S325). The central fragrance component and the peripheral fragrance component are classified based on the amount of the chemical component.

The encoding unit 120 converts the amount of the chemical component of the central incense component and the peripheral incense component into gray scale and expresses it as color information (S330). Then, the encoding unit 120 generates a value converted to grayscale into a packet, and transmits the packet via the network (S335).
