[0030] FIG. 1 is a drawing illustrating the configuration of a system according to one embodiment of the present disclosure.

[0031] Referring to FIG. 1, the system (1000) may include an evaluation device (100), a customer terminal (200), etc.

[0032] The evaluation device (100) is a device for managing the safety mark of a product.

[0033] In one embodiment, the evaluation device (100) may correspond to a server that provides guidance services for safety marks.

[0034] For example, the evaluation device (100) may be implemented as a server device or system including at least one computer and may be an entity operating a platform that provides guidance services for safety marks. Specifically, the evaluation device (100) may provide guidance services for safety marks by communicating with multiple terminal devices through at least one web page, application, software (computer program), etc., that constitute the platform.

[0035] Additionally, the evaluation device (100) may be implemented as various terminal devices. For example, the evaluation device (100) may correspond to a user's terminal such as a desktop PC, tablet PC, laptop PC, smartphone, or wearable device, or it may be implemented as a kiosk installed in a specific location, public PC, etc.

[0036] In addition, the evaluation device (100) can be implemented as various servers or terminal devices.

[0037] The customer terminal (200) may correspond to the terminal device of a customer requesting validation of the safety mark.

[0038] In one embodiment, a customer terminal (200) can access a platform provided by an evaluation device (100), input information about a safety mark (e.g., an image, identification information of a product with a safety mark attached, etc.), request guidance information about the safety mark, and obtain guidance information about the safety mark.

[0039] Here, the guidance information requested by the customer terminal (200) may include, but is not limited to, verification of the validity of the safety mark, explanation of the information indicated by the safety mark, etc.

[0040] FIG. 2 is a diagram illustrating the operation of an evaluation device generating a safety mark and providing guidance information about the safety mark to a customer terminal according to an embodiment of the present disclosure.

[0041] Referring to FIG. 2, the evaluation device (100) can identify the safety rating and fire rating of the product (S210).

[0042] In one embodiment, the evaluation device (100) can identify the safety rating and fire rating of a product based on test data and product information for the product.

[0043] Here, test data may include thermal energy information generated by the combustion of the product (e.g., heat of combustion, etc.), mass information of the product that changes according to the combustion of the product, oxygen consumption according to the combustion of the product, combustion time, etc., and product information may include items such as at least one material constituting the product (e.g., plastic, metal, ceramic, etc.), type of energy required for the operation of the product (e.g., electricity, battery, oil, etc.), use of the product (e.g., cooking, bathroom, heating, cooling, daily life, etc.), image of the product, product identification information (e.g., model name, product name, etc.), and type of product (e.g., water purifier, electric rice cooker, refrigerator, washing machine, vacuum cleaner, etc.).

[0044] In one embodiment, the evaluation device (100) can calculate the heat release rate generated according to the combustion of the product based on test data. Here, the heat release rate (HRR) refers to the rate at which the chemical energy of the fuel is converted into thermal energy due to combustion.

[0045] For example, the evaluation device (100) can identify the rate at which the thermal energy generated by the combustion of the product and the mass of the product change based on test data.

[0046] Specifically, the evaluation device (100) can identify the heat of combustion per unit mass generated according to the combustion of the product from the thermal energy information included in the test data. Heat of combustion refers to the amount of energy released as heat as the product burns.

[0047] In addition, the evaluation device (100) can calculate the rate at which the mass of the product changes based on the mass information of the product included in the test data.

[0048] Through this, the evaluation device (100) can calculate the heat release rate per unit time of the product by multiplying the combustion heat and mass change rate per unit mass of the product.

[0049] As an additional example, the evaluation device (100) may calculate the heat release rate per unit time based on the oxygen consumption per unit time due to the combustion of the product and the heat value generated as 1 kg of oxygen is burned (e.g., 13.1 MJ / kg).

[0050] At this time, the evaluation device (100) can calculate a grade index indicating the risk of fire occurring to the product by dividing the maximum value of the heat release rate per unit time by the initial mass of the product, and can identify the safety grade of the product based on the grade index.

[0051] For example, the evaluation device (100) can identify the safety grade as Grade 1 if the grade index is included in 0-6.0, identify the safety grade as Grade 2 if the grade index is included in 6.1-12.0, identify the safety grade as Grade 3 if the grade index is included in 12.1-18.0, identify the safety grade as Grade 4 if the grade index is included in 18.1-24.0, identify the safety grade as Grade 5 if the grade index is included in 24.1-30.0, identify the safety grade as Grade 6 if the grade index is 30.1-36.0, and identify the safety grade as Grade 7 if the grade index is 36.1 or higher.

[0052] Through this, the evaluation device (100) can set the safety grade such that the risk of fire is highest as the safety grade approaches grade 7.

[0053] In addition, the evaluation device (100) can identify a fire grade indicating the characteristics of a fire occurring to a product based on product information.

[0054] Specifically, the evaluation device (100) can identify the fire rating of a product based on at least one material constituting the product, the type of energy required to drive the product, and at least one of the use of the product.

[0055] For example, the evaluation device (100) can classify fire grades according to the NFPA (The National Fire Protection Association) regulations.

[0056] For example, the evaluation device (100) can identify the fire characteristics of a product composed of wood, paper, plastic, etc. as an ordinary fire, the fire characteristics of a product using flammable liquid or gas as an oil fire, the fire characteristics of an electrically driven product as an electric fire, the fire characteristics of a product composed of metal as a metal fire, and the fire characteristics of a product used in a kitchen as a kitchen fire, and can identify the fire grade of an ordinary fire as A, the fire grade of an oil fire as B, the fire grade of an electric fire as C, the fire grade of a metal fire as D, and the fire grade of a kitchen fire as K.

[0057] As an additional example of implementation, the evaluation device (100) may obtain the safety rating and fire rating of the product through user input.

[0058] Additionally, the evaluation device (100) can calculate the time at which the heat release rate has a difference value less than the maximum value of the heat release rate and a reference value, and set this time as the target time.

[0059] At this time, the evaluation device (100) can additionally set a warning grade of the product based on the ratio of the target time to the combustion time included in the product's test data.

[0060] For example, the evaluation device (100) can set a higher warning grade as the proportion of the target time to the combustion time increases.

[0061] The evaluation device (100) can generate a safety mark for the product (S220).

[0062] In one embodiment, the evaluation device (100) can generate a safety mark indicating the safety rating and fire rating of a product according to design information including a preset color for each rating constituting the safety rating and fire rating.

[0063] The design information may include a template that includes the location where the safety rating is displayed, the location where the fire rating is displayed, etc. In this case, the evaluation device (100) can generate a safety mark by arranging the safety rating and the fire rating according to the template.

[0064] As an additional example, the evaluation device (100) may obtain a safety mark of the product through user input.

[0065] The evaluation device (100) can add information about the product to the evaluation history (S230).

[0066] In one embodiment, the evaluation device (100) can add test data, product information, and safety marks for a product to an evaluation history containing safety marks that have already been generated for each of a plurality of products.

[0067] Meanwhile, the evaluation device (100) can additionally match and store the product's warning grade in the evaluation history.

[0068] Through this, the evaluation device (100) can establish a foundation for providing guidance services for safety marks.

[0069] Additionally, when the evaluation device (100) receives at least one of new test data and product information for the same product, it can identify the safety rating and fire rating based on the newly received test data and product information, generate a new safety mark, and add it to the evaluation history.

[0070] At this time, the evaluation device (100) can identify whether the fire grade matches by comparing the existing safety mark, which is a safety mark added to the evaluation history at an earlier point in time, and the additional safety mark, which is a safety mark newly added to the evaluation history.

[0071] Specifically, the evaluation device (100) can identify modified items by comparing the fire grade indicated by the existing safety mark of a product and the fire grade indicated by the additional safety mark of a product, and if it is identified that the fire grades do not match, it can identify modified items by comparing the items included in the product information that formed the basis for creating the existing safety mark and the items included in the product information that formed the basis for creating the additional safety mark.

[0072] In this case, the evaluation device (100) may calculate the difference value between the grade index calculated from the test data that formed the basis for generating the existing safety mark and the grade index calculated from the test data that formed the basis for generating the additional safety mark, and may generate analysis information including the modified item, information on the increase or decrease of the grade index, and the difference value, or add it to the analysis information that has already been generated. The analysis information may correspond to information that is generated or updated to identify the effect that each item included in the product information has on the grade index.

[0073] Through this, the evaluation device (100) can calculate the number of times the grade index has decreased and the number of times it has increased for each item included in the product information based on the analysis information. Here, the evaluation device (100) can set the item with the most decreases in the grade index among the items included in the product information as a safe item, and the item with the most increases in the grade index as a risk item.

[0074] At this time, if two or more items with the highest number of times the grade index has decreased are identified, the evaluation device (100) can set the items with the highest number of times the grade index has decreased as candidate safe items. In this case, the evaluation device (100) can calculate the average of the difference values ​​matched with each candidate safe item for each candidate safe item, and set the candidate safe item with the largest calculated average value as a safe item.

[0075] Additionally, if two or more items with the highest number of increases in the grade index are identified, the evaluation device (100) may set the items with the highest number of increases in the grade index as candidate risk items. In this case, the evaluation device (100) may calculate the average of the difference values ​​matched with each candidate risk item for each candidate risk item, and set the candidate risk item with the largest average value as the risk item.

[0076] In addition, the evaluation device (100) can set safety items and risk items whenever new data is added to the analysis information.

[0077] At this time, the evaluation device (100) can classify the safety marks included in the evaluation history according to the manufacturer and calculate the average safety grade of the safety grade indicated by the safety marks for each manufacturer. Here, the evaluation device (100) can transmit information regarding safety items and risk items to a terminal of a manufacturer whose average safety grade is below the standard grade.

[0078] As a result, the evaluation device (100) can help manufacturers with low average safety ratings for their products develop products with improved safety ratings.

[0079] Meanwhile, the customer terminal (200) can request the evaluation device (100) to provide information about the target safety mark (S240).

[0080] Specifically, the customer terminal (200) can request the provision of information regarding the target safety mark by transmitting identification information of the target safety mark and the target product with the target safety mark attached to the evaluation device (100).

[0081] Upon request from the customer terminal (200), the evaluation device (100) can verify the validity of the target safety mark (S250).

[0082] In one embodiment, the evaluation device (100) may verify the validity of the target safety mark by identifying whether the safety grade and fire grade indicated by the target safety mark match the safety grade and fire grade identified according to the test data of the target product.

[0083] Specifically, the evaluation device (100) can obtain product information including identification information of a target product from an evaluation history and test data matched with said product information, calculate a grade index of the target product based on said test data to identify a safety grade, and identify a fire grade by identifying fire characteristics based on said product information.

[0084] Here, the evaluation device (100) can determine the validity of the target safety mark by comparing the safety rating and fire rating identified based on test data and product information with the safety rating and fire rating indicated by the target safety mark.

[0085] Additionally, the evaluation device (100) may verify the validity of the target safety mark by identifying whether the target safety mark corresponds to a safety mark for the target product.

[0086] Specifically, the evaluation device (100) can obtain a safety mark matched with product information including identification information of the target product from the evaluation history and set it as a comparison safety mark.

[0087] Accordingly, the evaluation device (100) can determine the validity of the target safety mark by comparing the safety grade and fire grade indicated by the comparison safety mark with the safety grade and fire grade indicated by the target safety mark.

[0088] For example, the evaluation device (100) can determine that the target safety mark is a valid safety mark if the safety grade and the fire grade match according to the comparison result, and determine that the target safety mark is an invalid safety mark if at least one of the safety grade and the fire grade does not match.

[0089] The evaluation device (100) can provide guidance information about the target safety mark to the customer terminal (200) (S260).

[0090] In one embodiment, when the validity of a target safety mark is verified based on test data and product information for a target product, the evaluation device (100) may provide guidance information including a grade index, information on the characteristics of a fire occurring for a target product, and the result of verifying the validity of the target safety mark to a customer terminal (200).

[0091] Additionally, when the validity of the target safety mark is verified based on the comparison safety mark, the evaluation device (100) can provide guidance information including a message indicating that the target safety mark is a reliable safety mark if the target safety mark is a valid safety mark, and can provide guidance information including the comparison safety mark along with a message indicating that the target safety mark is an invalid safety mark to the customer terminal (200) if the target safety mark is an invalid safety mark.

[0092] In this case, the evaluation device (100) may request the customer terminal (200) to transmit purchase information (e.g., place of sale, manufacturer, etc.) regarding a product with an invalid safety mark attached.

[0093] When purchase information is received from a customer terminal (200), the evaluation device (100) can send a correction request message to a terminal of a manufacturer or seller included in the purchase information.

[0094] Specifically, the evaluation device (100) can collect contact information of a manufacturer or seller (e.g., email address, phone number, etc.) by performing a search on a pre-configured search web page based on at least one keyword constituting purchase information.

[0095] Through this, the evaluation device (100) can send a correction request message with the collected contact information.

[0096] As an additional example of implementation, when an explanation regarding the safety grade and fire grade indicated by the target safety mark is requested from the customer terminal (200), the evaluation device (100) may provide guidance information to the customer terminal (200) including the risk of fire according to the safety grade indicated by the target safety mark, the characteristics of the fire indicated by the fire grade, and countermeasures.

[0097] In addition, the evaluation device (100) can obtain a safety rating for the product of the manufacturer that manufactured the target product from the evaluation history.

[0098] At this time, the evaluation device (100) may calculate the average safety rating of the product of the manufacturer that manufactured the target product, and provide guidance information including the average safety rating of the manufacturer to the customer terminal (200).

[0099] Here, if the average safety rating for the manufacturer is lower than the preset rating, the evaluation device (100) may provide guidance information to the customer terminal (200) that includes a message indicating that caution is required when using the product.

[0100] Additionally, the evaluation device (100) may calculate the average safety rating of a product of the same type as the target product (e.g., water purifier, electric rice cooker, refrigerator, fan, etc.) and provide guidance information including the average safety rating for the product type to the customer terminal (200).

[0101] At this time, if the safety rating of the target product is lower than the average safety rating for the type of product and the difference between the average safety rating for the type of product and the safety rating of the target product exceeds a preset value, the evaluation device (100) may provide guidance information to the customer terminal (200) that includes a message indicating that caution is required for product use.

[0102] Additionally, if the safety rating of the target product is higher than the average safety rating for the product type, and the difference between the average safety rating for the product type and the safety rating of the target product exceeds a preset value, the evaluation device (100) may provide guidance information to the customer terminal (200) that includes a message indicating that the target product is a product with a relatively low fire risk.

[0103] Additionally, the evaluation device (100) can identify the warning level of each product that has the same safety level as the target product and calculate the average value of the identified warning levels. Through this, the evaluation device (100) can obtain the average warning level for the safety level of the target product.

[0104] Here, the evaluation device (100) can compare the average warning level of the target product and the safety level of the target product.

[0105] At this time, if the warning level of the target product is higher than the average warning level for the safety level of the target product, the evaluation device (100) may provide guidance information to the customer terminal (200) that further includes a message indicating that the target product is a relatively safe product.

[0106] Additionally, if the warning level of the target product is lower than the average warning level for the safety level of the target product, the evaluation device (100) may provide guidance information to the customer terminal (200) that further includes a message indicating that the target product is a relatively dangerous product.

[0107] FIG. 3 is a diagram illustrating the operation of an evaluation device communicating with a manager device according to one embodiment of the present disclosure.

[0108] Referring to FIG. 3, the evaluation device (100) can communicate with the manager device (300).

[0109] The manager device (300) may correspond to a manager's device that identifies the safety and fire ratings of various products and generates a safety mark based on the safety and fire ratings.

[0110] In this case, the evaluation device (100) may be a device that generates a safety mark based on the safety rating and fire rating received from the manager device (300), adds the safety mark received from the manager device (300) to the evaluation history, and performs validation according to the information provision request received from the customer terminal (200).

[0111] In one embodiment, the evaluation device (100) can obtain the safety rating and fire rating of a product from the manager device (300).

[0112] In addition, the evaluation device (100) may also obtain a safety mark of a product from the manager device (300).

[0113] FIG. 4 is a drawing for explaining an example of attaching a safety mark according to one embodiment of the present disclosure.

[0114] The evaluation device (100) can obtain an image of a product with a safety mark attached, as shown in FIG. 4.

[0115] In one embodiment, if the evaluation device (100) identifies that the target safety mark is invalid, it may request the transmission of an image of the target product to the customer terminal (200).

[0116] When a customer terminal (200) transmits at least one target image of a target product to an evaluation device (100) in response to an image transmission request, the evaluation device (100) can obtain a product image included in product information matched with the identification information of the target product from the evaluation history.

[0117] Here, the evaluation device (100) can calculate the similarity between the product image and the target image.

[0118] For example, the evaluation device (100) can obtain the similarity between the product image and the target image based on the output data by inputting the product image and the target image into at least one artificial intelligence model trained to calculate the similarity between images.

[0119] An artificial intelligence model may be a model trained to extract feature vectors from each image and measure similarity between images based on the distance or angle between the extracted feature vectors, and may be trained based on various algorithms such as Convolutional Neural Networks (CNNs), autoencoders, and Siamese Networks, but is not limited thereto.

[0120] Additionally, the evaluation device (100) can generate a histogram for each of the product image and the target image, and identify the similarity between the images by comparing the generated histograms.

[0121] Additionally, the evaluation device (100) may extract feature information from each of the product image and the target image, and identify the similarity between the images by comparing the extracted feature information. For example, the evaluation device (100) may extract feature information from the image using at least one of various algorithms such as SIFT (Scale-Invariant-Feature Transform), ORB (Oriented FAST and Rotated BRIEF), and SURF (Speeded Up Robust Features).

[0122] At this time, if the similarity is below a threshold, the evaluation device (100) determines that the identification information received from the customer terminal (200) is not the identification information of the target product and may request the customer terminal (200) to reconfirm the identification information of the target product.

[0123] Additionally, if the similarity exceeds a threshold, the evaluation device (100) can identify the number of safety marks of the target product included in the evaluation history.

[0124] At this time, if there are multiple safety marks of the target product included in the evaluation history, the evaluation device (100) can request the customer terminal (200) to transmit the time of purchase of the target product.

[0125] When the customer terminal (200) transmits the purchase time of the target product to the evaluation device (100), the evaluation device (100) can compare the purchase time received from the customer terminal (200) with the time when each of the multiple safety marks of the target product is added to the evaluation history.

[0126] Through this, the evaluation device (100) can identify whether there is a safety mark added prior to the time of purchase received from the customer terminal (200) among the safety marks for the target product included in the evaluation history.

[0127] At this time, if a safety mark added to the evaluation history prior to the time of purchase is identified among the multiple safety marks for the target product, the evaluation device (100) can verify the validity of the target safety mark based on the safety mark added to the evaluation history prior to the time of purchase and the target safety mark.

[0128] If, among the multiple safety marks for a target product, a safety mark added to the evaluation history prior to the time of purchase is not identified, the evaluation device (100) can transmit guidance information including a message to the customer terminal (200) indicating that the target safety mark is an invalid safety mark.

[0129] In this case, the evaluation device (100) may request the customer terminal (200) to transmit purchase information (e.g., place of sale, manufacturer, etc.) regarding a product with an invalid safety mark attached.

[0130] When purchase information is received from a customer terminal (200), the evaluation device (100) can send a correction request message to a terminal of a manufacturer or seller included in the purchase information.

[0131] Specifically, the evaluation device (100) can collect contact information of a manufacturer or seller (e.g., email address, phone number, etc.) by performing a search on a pre-configured search web page based on at least one keyword constituting purchase information.

[0132] Through this, the evaluation device (100) can send a correction request message with the collected contact information.

[0134] Referring to FIG. 5, the safety mark may include a safety rating of the product, fire characteristics of the product, fire rating of the product, and a risk indicator showing a color set for each safety rating of the product.

[0135] In one embodiment, the evaluation device (100) can generate a safety mark according to design information including a preset color for each grade constituting the safety grade and the fire grade.

[0136] Here, the design information may include a color range including colors pre-set for each grade constituting the safety grade and colors pre-set for each grade constituting the fire grade, a template including the location where the safety grade is placed on the safety mark, the location where the fire grade is placed, etc.

[0137] Here, the design information may include basic design information including a basic color range, and at least one of a first design information including a color range for red color blindness or red deficiency, a second design information including a color range for green color blindness or green deficiency, a third design information including a color range for blue deficiency or blue blindness, and a fourth design information including a color range for total color deficiency or total color blindness.

[0138] Specifically, the color range included in the basic design information may include setting values ​​for R (red), G (green), and B (blue) values ​​among the RGB values, the color range included in the first design information may include setting values ​​for G and B values ​​among the RGB values, the color range included in the second design information may include setting values ​​for R and B values ​​among the RGB values, the color range included in the third design information may include setting values ​​for R and G values ​​among the RGB values, and the color range included in the fourth design information may include setting values ​​for S (saturation) and B (brightness) values ​​among HSB values ​​that are not RGB values.

[0139] Accordingly, the evaluation device (100) can generate a basic safety mark according to basic design information and generate at least one of a first safety mark according to first design information, a second safety mark according to second design information, a third safety mark according to third design information, and a fourth safety mark according to fourth design information.

[0140] In one embodiment, a customer terminal (200) may transmit identification information of a target product and color vision information of a customer to an evaluation device (100) and request the transmission of a safety mark corresponding to the color vision information. Here, the color vision information may include information regarding color deficiency or color blindness of the customer of the customer terminal (200).

[0141] Accordingly, the evaluation device (100) can obtain the basic safety mark and the first to fourth safety marks of the target product from the evaluation history based on the identification information of the target product, and transmit the safety mark corresponding to the customer's color vision information among the obtained safety marks to the customer terminal (200).

[0142] For example, if the evaluation device (100) identifies that the customer is red-blind based on the customer's color vision information, it can provide a first safety mark to the customer terminal (200).

[0149] When a safety mark is generated, the evaluation device (100) can transmit information about the safety rating, fire rating, and safety mark of a product to a company terminal (500).

[0150] Through this, the company of the company terminal (500) can attach a safety mark to a product and sell or produce it, and the customer terminal (200) of the customer who purchased the product can request the provision of information about the safety mark through the evaluation device (100).

[0151] Additionally, when a preset time has elapsed since the time when the safety mark of a product is registered in the evaluation history, the evaluation device (100) may request the transmission of a message indicating that the safety mark of the product needs to be updated to the company terminal (500) of the company that manufactures / sells / imports the product.
