[0027] Hereinafter, the embodiments will be described in detail with reference to the drawings.

[0028] FIG. 1 is a block diagram that schematically illustrates the configuration of a device 100 for providing grade-related information for tramp ferrous scrap, according to one embodiment of the present disclosure.

[0029] Referring to FIG. 1, a device 100 for providing grade-related information for tramp ferrous scrap may include a receiver 110 and a processor 120 .

[0030] According to an embodiment, the receiving unit 110 can acquire policy information regarding a grading standard for mixed iron scrap in which a first type of iron scrap and a second type of iron scrap are mixed.

[0031] According to an embodiment, the processor 120 may determine the normal purchase price for each of the first type of iron scrap and the second type of iron scrap based on the policy information. The processor 120 may also determine a weighted average unit price for the tramp iron scrap based on the ratio of the first type of iron scrap, the ratio of the second type of iron scrap, and the normal purchase price. The processor 120 may also determine the grade of the tramp iron scrap as either a first grade corresponding to the first type of iron scrap or a second grade corresponding to the second type of iron scrap based on a comparison result between the critical weighted average unit price determined based on the policy information and the weighted average unit price.

[0032] In addition, the device 100 for providing information related to the grade of tramp iron scrap may acquire policy information on grade criteria for tramp iron scrap using the receiving unit 110, determine a normal purchase price for the iron scrap using the processor 120, determine a weighted average price for the tramp iron scrap based on the ratio of the first type of iron scrap, the ratio of the second type of iron scrap, and the normal purchase price, determine the grade of the tramp iron scrap as either a first grade corresponding to the first type of iron scrap or a second grade corresponding to the second type of iron scrap, and provide the grade and related information of the iron scrap. Note that the process may be combined using a combination of various conventional networks such as the Internet network or a mobile communication network, and there is no particular limitation thereon.

[0033] In addition, it will be understood by those skilled in the art that other general components may be included in device 100 for providing information related to the grade of tramp ferrous scrap in addition to the components shown in Figure 1. For example, device 100 for providing information related to the grade of tramp ferrous scrap may further include a memory (not shown) for storing policy information regarding grading criteria for tramp ferrous scrap and grade information corresponding to the tramp ferrous scrap, and may further include a transmitter (not shown) for providing grade information of the tramp ferrous scrap or a display (not shown) for displaying grade information of the tramp ferrous scrap. It will also be understood by those skilled in the art that some of the components shown in Figure 1 may be omitted in other embodiments.

[0034] The device 100 for providing grade-related information for tramp iron scrap according to one embodiment can be used by a user and can be connected to all kinds of handheld-based wireless communication devices equipped with a touch screen panel, such as a mobile phone, a smartphone, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia Player), a tablet PC, etc., and can also be included in or connected to devices equipped with a platform on which an application can be installed and executed, such as a desktop PC, a tablet PC, a laptop PC, and an IPTV including a set-top box.

[0035] The device 100 for providing grade-related information for tramp ferrous scrap may be embodied in a terminal such as a computer operating through a computer program to implement the functions described herein.

[0036] The device 100 for providing grade-related information for tramp ferrous scrap according to one embodiment may include, but is not limited to, a system for providing classification information for ferrous scrap (not shown) and a related server (not shown). The server according to one embodiment may support an application that provides a service for providing grade-related information for tramp ferrous scrap.

[0037] The following description will focus on an embodiment in which the device 100 for providing information related to the grade of tramp iron scrap according to an embodiment independently acquires and provides information related to the grade of tramp iron scrap that has been preset, but as described above, this may be performed through interlocking with a server. That is, the device 100 for providing information related to the grade of tramp iron scrap according to an embodiment and the server may be integrated in terms of their functions, or the server may be omitted, and it is understood that the present invention is not limited to any one embodiment.

[0038] In one embodiment, the device 100 for providing information related to the grade of tramp ferrous scrap and a server may be linked, and the configuration for providing information on tramp ferrous scrap by performing a tramp ferrous scrap grade determination process and a tramp ferrous scrap judgment grade information provision process may be performed by the server or may be performed by the device 100 for providing information related to the grade of tramp ferrous scrap. For example, the device 100 for providing information related to the grade of tramp ferrous scrap may operate as a server, and hereinafter, will be referred to as the device 100 for providing information related to the grade of tramp ferrous scrap.

[0039] FIG. 2 is a flow chart illustrating steps by which device 100 provides grade-related information for tramp ferrous scrap according to one embodiment of the present disclosure.

[0040] Referring to step S210, the device 100 according to one embodiment may acquire policy information regarding grade criteria for tramp scrap, which is a mixture of a first type of tramp scrap and a second type of tramp scrap. In one embodiment, the device 100 may acquire policy information corresponding to each of a plurality of company accounts. In this case, the policy information may include the type of tramp scrap, the normal purchase price of each of the plurality of tramp scrap, and a plurality of tramp scrap grades. In addition, in one embodiment, the device 100 may acquire policy information including information regarding a mixing allowance ratio indicating a mixing allowance standard between a plurality of tramp scrap grades.

[0041] Referring to step S220, the device 100 according to an embodiment may determine a normal purchasing price for each of the first type of iron scrap and the second type of iron scrap based on the policy information. In an embodiment, the device 100 may obtain a normal purchasing price for each of the acquired iron scrap based on the policy information. Thus, the device 100 may determine a normal purchasing price for each of the first type of iron scrap and the second type of iron scrap.

[0042] Referring to step S230, the device 100 according to an embodiment can determine a weighted average unit price for the tramp iron scrap based on the ratio of the first type of iron scrap, the ratio of the second type of iron scrap, and the normal purchasing price. In one embodiment, the device 100 can acquire iron scrap classification information including information such as the types of tramp iron scrap mixed into the loading equipment and stored, iron scrap grade information corresponding to the multiple iron scrap types, and the iron scrap ratio of each of the mixed iron scrap from the receiving unit 110. Therefore, the device 100 can determine a weighted average unit price for the tramp iron scrap based on the acquired types of tramp iron scrap, the mixing ratios corresponding to each of the multiple iron scrap types, and the normal purchasing price.

[0043] Referring to step S240, the device 100 according to one embodiment may determine the grade of the tramp iron scrap as either a first grade corresponding to a first type of iron scrap or a second grade corresponding to a second type of iron scrap based on a comparison result between the critical weighted average unit price determined based on the policy information and the weighted average unit price.

[0044] In one embodiment, the device 100 may determine a minimum normal purchase price indicating a minimum normal purchase price for the first type of iron scrap based on the policy information. In one embodiment, the minimum normal purchase price may indicate a critical weighted average price.

[0045] FIG. 3 is an example of a screen display in which the device 100 obtains policy information according to an embodiment of the present disclosure.

[0046] Referring to FIG. 3, in one embodiment, device 100 may acquire the types of first and second types of iron scrap and the normal purchase price corresponding to each type of iron scrap. Device 100 may also acquire a mixed-loading allowance ratio indicating the iron scrap mixed-loading allowance standard for mixed iron scrap. For example, if the mixed-loading allowance ratio of the first and second types of iron scrap is 7:3, device 100 may determine the allowable ratio as 70% and the unallowable ratio as 30%. Therefore, if the ratio of the first type of iron scrap in the mixed iron scrap stored in the loading equipment is 70% or more, the mixed iron scrap may be classified as grade 1, which corresponds to the first type of iron scrap. Furthermore, if the ratio of the first type of iron scrap in the mixed iron scrap is 70% or less, the mixed iron scrap may be classified as grade 2, which corresponds to the second type of iron scrap.

[0047] In one embodiment, the grade of the first type of ferrous scrap may be higher than the grade of the second type of ferrous scrap. Specifically, the device 100 may determine a higher grade for heavier ferrous scrap based on the weight of the ferrous scrap. Specifically, the first type of ferrous scrap may be a type of ferrous scrap that is heavier than the second type of ferrous scrap. (For example, the first type of ferrous scrap may correspond to heavy ferrous scrap, and the second type of ferrous scrap may correspond to light ferrous scrap. Therefore, the first type of ferrous scrap may typically have a higher purchase price than the second type of ferrous scrap, and the first type of ferrous scrap may be a higher grade than the second type of ferrous scrap.)

[0048] In one embodiment, the device 100 may acquire information on the weight, thickness, and length of the scrap iron. The device 100 may also determine the grade of the scrap iron by assigning different weights to the weight, thickness, and length of the scrap iron. For example, the device 100 may assign the highest weight to the thickness of the scrap iron to determine the grade of tramp scrap iron. Scrap iron is waste iron or iron products and is a raw material for smelting and recycling steel, and is also a raw material for recycling waste cast iron purchased elsewhere. Generally, the fewer impurities iron contains, the better its quality. Since it can be determined that scrap iron with fewer impurities, such as carbon, is heavier, the device 100 may assign the highest weight to heavier scrap iron to determine the grade of the scrap iron.

[0049] In another embodiment, the device 100 may assign the greatest weight to the length of the scrap iron to determine the grade of the scrap iron. The scrap iron must be loaded into an electric furnace and melted. That is, the scrap iron must be stacked in a blast furnace or the like and melted. During this process, excessively large scrap iron cannot be loaded into an electric furnace without undergoing a separate processing process. Therefore, scrap iron that has been cut to a size that can be loaded into an electric furnace is most preferred. Therefore, the device 100 may assign the greatest weight to the length of the scrap iron to determine the grade of the scrap iron.

[0050] In one embodiment, as described above, since users corresponding to multiple company accounts may have different preferences for the types of scrap iron, the device 100 determines the grade of scrap iron by assigning different weights to the scrap iron grade determination factors to suit each situation, which is effective in improving user satisfaction.

[0051] In one embodiment, in the step of determining whether the grade of the tramp iron scrap is one of grade 1 and grade 2, if the weighted average unit price is greater than the minimum normal purchase price, the device 100 may determine the grade of the tramp iron scrap as grade 1. In one embodiment, the minimum normal purchase price may indicate the minimum normal purchase price of the first type of iron scrap. As described in step S240, the device 100 may determine the grade of the tramp iron scrap based on a comparison result between the minimum normal purchase price, which indicates the critical weighted average unit price determined based on the policy information, and the weighted average unit price of the tramp iron scrap.

[0052] FIG. 4 is an example of a table in which the device 100 according to an embodiment of the present disclosure determines and provides the normal unit purchase price and the minimum normal unit purchase price of iron scrap based on policy information.

[0053] Referring to FIG. 4, the device 100 according to an embodiment can acquire the normal purchase price and the minimum normal purchase price for weight A, weight B, light A, and light B iron scrap, respectively. For example, referring to FIG. 4, the device 100 may determine that the first type of iron scrap in the tramp iron scrap corresponds to weight A, the second type of iron scrap corresponds to weight B, and the mixed ratio of the first type of iron scrap to the second type of iron scrap in the tramp iron scrap is 8:2. Furthermore, as described in step S230, the device 100 may determine the weighted average unit price of the tramp iron scrap based on the ratio of the first type of iron scrap, the ratio of the second type of iron scrap, and the normal purchase price. Therefore, the device 100 may determine the weighted average unit price of the tramp iron scrap to be 483 won per kg (485 × 0.8 + 475 × 0.2). In addition, the device 100 may determine that the weighted average unit price of the tramp iron scrap is greater than 482 won per kg, which is the minimum normal purchase price of weight A, which is the first type of iron scrap. Therefore, the device 100 may determine the grade of the tramp iron scrap to be grade 1.

[0054] In addition, in one embodiment, if the weighted average unit price of the device 100 is less than the minimum normal purchase price, the grade of the tramp iron scrap may be determined to be grade 2. In one embodiment, the minimum normal purchase price may indicate the minimum normal purchase price of the first type of iron scrap.

[0055] 4, for example, device 100 may determine that the first type of tramp iron scrap corresponds to weight A, the second type of tramp iron scrap corresponds to weight B, and the mixed ratio of the first type of tramp iron scrap to the second type of tramp iron scrap is 6:4. Therefore, device 100 may determine the weighted average unit price of the tramp iron scrap to be 481 won per kg (485 x 0.6 + 475 x 0.4). Furthermore, device 100 may determine that the weighted average unit price of the tramp iron scrap is less than 482 won per kg, which is the minimum normal purchase price of weight A of the first type of tramp iron scrap, and therefore may determine the grade of the tramp iron scrap to be grade 2.

[0056] FIG. 5 is an example screen display showing a device 100 providing tramp ferrous scrap grading results according to one embodiment of the present disclosure.

[0057] Referring to FIG. 5, in one embodiment, device 100 may provide, via a display screen, a grade determination result for tramp ferrous scrap received and mixed into loading equipment. In one embodiment, device 100 may determine that the ratio of the first type of ferrous scrap to the second type of ferrous scrap is 6:4. As previously described in the example, device 100 may determine that the weighted average unit price of the tramp ferrous scrap is 481 won per kilogram. Device 100 may also determine that the weighted average unit price of the tramp ferrous scrap is less than 482 won per kilogram, which is the minimum normal purchase price and represents the critical weighted average unit price. Therefore, in one embodiment, device 100 may determine that the grade of the tramp ferrous scrap is Grade 2, which corresponds to the second type of ferrous scrap. In addition, the device 100 provides the determined grade determination result of the tramp iron scrap on a display screen, thereby preventing errors that occur in the final grading process performed manually by inspectors, as in the conventional technology, and can consistently and accurately determine and provide the grade of the tramp iron scrap. Therefore, the accuracy of the grade determination result of the tramp iron scrap can be improved, thereby improving the convenience and satisfaction of users.

[0058] In the step of determining the minimum normal purchasing price, the device 100 according to an embodiment may determine a purchasing price difference value indicating a difference between a first normal purchasing price for the first type of iron scrap and a second normal purchasing price for the second type of iron scrap. In addition, the device 100 may determine the minimum normal purchasing price by applying a consolidation allowance ratio to the purchasing price difference value.

[0059] Referring to FIG. 4, the device 100 according to an embodiment may acquire policy information regarding grade determination criteria for mixed tramp iron scrap from the receiving unit 110. The device 100 may also determine the normal purchase price corresponding to each type of iron scrap based on the policy information. Accordingly, the device 100 may determine a purchase price difference value indicating the difference between the normal purchase prices of each type of iron scrap. For example, the device 100 may determine that a first type of iron scrap corresponds to weight A and a second type of iron scrap corresponds to weight B. In this case, the normal purchase price of weight A corresponds to 485 won per kg, and the price of weight B corresponds to 475 won per kg, so the device 100 may determine the purchase price difference value to be 10 won per kg.

[0060] In the step of determining the minimum normal purchase price by applying the consolidation allowance ratio to the purchase price difference, the device 100 according to an embodiment may determine an allowable threshold value corresponding to the product of the unallowable ratio determined by the consolidation allowance ratio and the purchase price difference. Also, the device 100 may determine the minimum normal purchase price to correspond to the first normal purchase price minus the allowable threshold value.

[0061] Referring to FIG. 4, the device 100 according to one embodiment may determine a purchase price difference value indicating the difference between the normal purchase prices to be 10 won per kg. The device 100 may also determine the weight of the first type of tramp iron scrap as A and the weight of the second type of tramp iron scrap as B. The allowable mixing ratio of the first type of tramp iron scrap to the second type of tramp iron scrap may be determined to be 7:3. Therefore, the unacceptable ratio may be set to 30% based on the allowable mixing ratio of the tramp iron scrap. The device 100 may determine the allowable threshold value to be 3 (3 won per kg), which corresponds to the product of the unacceptable ratio and the purchase price difference value, and may determine the minimum normal purchase price to be 482 won per kg, which is calculated by subtracting the allowable threshold value of 3 from the first normal purchase price of 485 won per kg.

[0062] Therefore, even if the normal purchase price for each grade of iron scrap fluctuates depending on the market conditions, the device 100 determines the minimum normal purchase price based on the purchase price difference value indicating the difference between the normal purchase prices for each grade and the mixed loading allowance ratio, and determines the grade of the mixed iron scrap by comparing the weighted average price of the mixed iron scrap with the minimum normal purchase price, thereby providing stable information.

[0063] FIG. 6 is an example of a table in which the device 100 according to an embodiment of the present disclosure determines and provides a score card based on policy information.

[0064] Referring to FIG. 6, the Score Card is a value obtained by converting the normal purchasing price of the highest grade of iron scrap type based on the normal purchasing price and the minimum normal purchasing price of iron scrap based on the policy information of FIG. 4 to 100, and then converting all values ​​shown in FIG. 4 using that standard as a basis. For example, as shown in FIGS. 4 and 5, the device 100 may determine the score of weight A to be 100. Also, the device 100 may determine the score of weight B to be 97.94 by applying a calculation formula that converts 485 won per kg to 100 as a basis. In this case, the device 100 may determine that digits to the third decimal place should be rounded when converting the normal purchasing price corresponding to each type of iron scrap into a score value. Therefore, in one embodiment, the device 100 may obtain policy information for each company through multiple company accounts and determine a Score Card value based on the policy information. Even if the normal purchasing price and mixed loading allowance ratio of each company's iron scrap changes depending on the market conditions, the device 100 provides a technology to automatically determine a constant price by applying the ScoreCard value, which has the effect of improving user satisfaction.

[0065] FIG. 7 is an example of loading equipment loaded with tramp iron scrap according to one embodiment of the present disclosure.

[0066] FIG. 8 is an example of a bird's-eye view of loading equipment loaded with tramp iron scrap according to one embodiment of the present disclosure.

[0067] 7 and 8, as described in step 230, the device 100 can further support a scrap iron analysis processor. The device 100 can determine scrap iron classification information for tramp scrap received in loading equipment through the scrap iron analysis process. That is, the device 100 can support both a processor that provides information related to the grade of tramp scrap and a scrap iron classification processor. In addition, the device 100 determines and provides the grade of tramp scrap based on the scrap iron classification information and policy information acquired from multiple company accounts. This reduces errors that occur when a person directly inspects and grades complex mixed tramp scrap without accurate standards, and provides information without error through AI-based assessment results without the hassle of manual inspection, thereby improving the accuracy of the information.

[0068] Various embodiments of the present disclosure may be embodied as software including one or more instructions stored in a storage medium (e.g., memory) readable by a machine (e.g., a display device or a computer). For example, a processor (e.g., processor 220) of the machine can retrieve and execute at least one of the one or more instructions stored in the storage medium. This allows the machine to operate to perform at least one function according to the retrieved at least one instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, "non-transitory" simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves). This term does not distinguish between data being stored semi-permanently and data being stored temporarily on the storage medium.

[0069] According to one embodiment, methods according to various embodiments disclosed in this disclosure may be provided in a computer program product. Computer program products may be traded as merchandise between sellers and buyers. Computer program products may be distributed in the form of a machine-readable storage medium (e.g., a compact disc read-only memory (CD-ROM)) or distributed online (e.g., downloaded or uploaded) through an application store (e.g., Play Store™) or directly between two user devices (e.g., smartphones). In the case of online distribution, at least a portion of the computer program product may be at least temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store server, or an intermediary server.

[0070] Although the present invention has been described with reference to illustrative drawings, it is not limited by the disclosed embodiments and drawings. Those skilled in the art will understand that the present invention may be embodied in various modified forms without departing from the essential characteristics of the above description. Therefore, the disclosed methods should be considered from an illustrative rather than a restrictive perspective. Even if the effects of the configurations of the present invention are not explicitly described in the description of the embodiments, predictable effects of the configurations may be recognized. The scope of the present invention is defined by the claims, not the above description, and all differences within the scope of equivalents thereto should be construed as being included in the present invention.
